Central Air Conditioners for Consumers(Are you a partner? For Partners)Heating and cooling costs the average homeowner about $1,000 a year — nearly half the home's total energy bill. If your central air conditioning unit is more than 12 years old, replacing it with an ENERGY STAR qualified model could cut your cooling costs by 30 percent. Earning the ENERGY STAR means products meet strict energy efficiency guidelines set by the US Environmental Protection Agency and the Department of STAR qualified central air conditioners have a higher seasonal efficiency rating (SEER) than standard models, which makes them about 14% more efficient than standard models. Remember, saving energy prevents pollution. By choosing ENERGY STAR and taking steps to optimize the performance of your cooling equipment, you are helping to prevent global warming and promoting cleaner air while enhancing the comfort of your may also be interested to know:Though these products can be more expensive to purchase up front, the cost difference will be paid back over time through lower energy bills. When buying new equipment, it is important to get a quality installation. Make sure you get a contractor who can do the job right.

Introduction The financial manager plays a dynamic role in a modern company’s development．This has not always been the case．Until around the first half of the 1900s financial managers primarily raised funds and managed their firms’cash positions-and that was pretty much it．In the 1950s,the increasing acceptance of present value concepts encouraged financial managers to expand their responsibilities and to become concerned with the selection of capital investment projects． Today external factors have an increasing impact on the financial corporate competition，technological change，volatility in inflation and interest rates，world-wide economic uncertainty，fluctuating exchange rates，tax law changes，and ethical concerns over certain financial dealings must be dealt with almost daily．As a result，finance is required to play an ever more vital strategic role within the corporation．The financial manager has emerged as a team player in the overall effort Of a company to create value．The“old ways of doing things”simply are not good enough in a world where old ways quickly become obsolete．Thus today's financial manager must have the flexibility to adapt to the changing external environment if his or her firm is to survive. The successful financial manager of tomorrow will need to supplement the traditional metrics of performance with new methods that encourage a greater role for uncertainty and multiple assumptions．These new methods will seek to value the flexibility inherent in initiatives—that is，the way in which taking one step offers you the option to stop or continue down one or more paths．In short，a correct decision may involve doing something today that in itself has small value，but gives you the option to do something of greater value in the future． If you become a financial manager，your ability to adapt to change，raise funds，invest in assets，and manage wisely will affect the success of your firm and，ultimately，the overall economy as well．To the extent that funds are misallocated，the growth of the economy will be slowed．When economic wants are unfulfilled，this misallocation of funds may work to the detriment of society．In an economy，efficient allocation of resources is vital to optimal growth in that economy；it is also vital to ensuring that individuals obtain satisfaction of their highest levels of personal wants．Thus，through efficiently acquiring，financing，and managing assets， the financial manager contributes to the firm and to the vitality and growth of the economy as a whole．简介 财务经理扮演一个积极的角色,在一个现代公司的并不总是周围 上半年,1900年财政管理,主要是筹集资金和管理,他们firms'cash阵地--这是相当 50年代起,越来越多的人接受目前的价值观念,鼓励财务经理,扩充自己的责任,很关心 e选择资本投资项目. 今天受外部因素的影响越来越大,财政企业竞争,技术变革,波动,通货膨胀率和利率上升,全球性的经济 不确定性,汇率波动时,税法的变化,和道德方面的某些金融交易必须处理几乎结果,是财政部 要发挥越来越重要的战略作用在转炉财务经理已经成为队球员 在整体的努力,公司创造"老办法办事"根本不是太好了 世界旧的方式迅速成为今天的财务经理必须要有一定的灵活性,以适应不断变化的外部 环境,只要他或她确实是为了生存. 成功的财务经理,明天将需要补充传统的度量的表现,与新方法,鼓励 更大的作用,对不确定性和多发性新方法将寻求价值的灵活性举措,即2001年的 在这一步,您可以选择停止或继续下跌的一个或多个总之, 正确的决定可能牵涉做一些事情,今天,在本身有小价值,而是让您选择做点事 更大的价值在未来. 如果你成为一个财务经理,你适应变

testing of an air-cycle refrigeration system for road transportAbstractThe environmental attractions of air-cycle refrigeration are considerable. Following a thermodynamic design analysis, an air-cycle demonstrator plant was constructed within the restricted physical envelope of an existing Thermo King SL200 trailer refrigeration unit. This unique plant operated satisfactorily, delivering sustainable cooling for refrigerated trailers using a completely natural and safe working fluid. The full load capacity of the air-cycle unit at −20 °C was 7,8 kW, 8% greater than the equivalent vapour-cycle unit, but the fuel consumption of the air-cycle plant was excessively high. However, at part load operation the disparity in fuel consumption dropped from approximately 200% to around 80%. The components used in the air-cycle demonstrator were not optimised and considerable potential exists for efficiency improvements, possibly to the point where the air-cycle system could rival the efficiency of the standard vapour-cycle system at part-load operation, which represents the biggest proportion of operating time for most : Air conditioner; Refrigerated transport; Thermodynamic cycle; Air; Centrifuge compressor; Turbine expander COP, NomenclaturePRCompressor or turbine pressure ratioTAHeat exchanger side A temperature (K)TBHeat exchanger side B temperature (K)TinletInlet temperature (K)ToutletOutlet temperature (K)ηcompCompressor isentropic efficiencyηturbTurbine isentropic efficiencyηheat exchangerHeat exchanger effectiveness1. IntroductionThe current legislative pressure on conventional refrigerants is well known. The reason why vapour-cycle refrigeration is preferred over air-cycle refrigeration is simply that in the great majority of cases vapour-cycle is the most energy efficient option. Consequently, as soon as alternative systems, such as non-HFC refrigerants or air-cycle systems are considered, the issue of increased energy consumption arises over legislation affecting HFC refrigerants and the desire to improve long-term system reliability led to the examination of the feasibility of an air-cycle system for refrigerated transport. With the support of Enterprise Ireland and Thermo King (Ireland), the authors undertook the design and construction of an air-cycle refrigeration demonstrator plant at LYIT and QUB. This was not the first time in recent years that air-cycle systems had been employed in transport. NormalAir Garrett developed and commercialised an air-cycle air conditioning pack that was fitted to high speed trains in Germany in the 90s. As part of an European funded programme, a range of applications for air-cycle refrigeration were investigated and several demonstrator plants were constructed. However, the authors are unaware of any other case where a self-contained air-cycle unit has been developed for the challenging application of trailer King decided that the demonstrator should be a trailer refrigeration unit, since those were the units with the largest refrigeration capacity but presented the greatest challenges with regard to physical packaging. Consequently, the main objective was to demonstrate that an air-cycle system could fit within the existing physical envelop and develop an equivalent level of cooling power to the existing vapour-cycle unit, but using only air as the working fluid. The salient performance specifications for the existing Thermo King SL200 vapour-cycle trailer refrigeration unit are listed .It was not the objective of the exercise to complete the design and development of a new refrigeration product that would be ready for manufacture. To limit the level of resources necessary, existing hardware was to be used where possible with the recognition that the efficiencies achieved would not be optimal. In practical terms, this meant using the chassis and panels for an existing SL200 unit along with the standard diesel engine and circulation fans. The turbomachinery used for compression and expansion was adapted from commercial . Thermodynamic modelling and design of the demonstrator plantThe thermodynamics of the air-cycle (or the reverse ‘Joule cycle’) are adequately presented in most thermodynamic textbooks and will not be repeated here. For anything other than the smallest flow rates, the most efficient machines available for the necessary compression and expansion processes are turbomachines. Considerations for the selection of turbomachinery for air-cycle refrigeration systems have been presented and discussed by Spence et al. [3]. a typical configuration of an air-cycle system, which is sometimes called the ‘boot-strap’ configuration. For mechanical convenience the compression process is divided into two stages, meaning that the turbine is not constrained to operate at the same speed as the primary compressor. Instead, the work recovered by the turbine during expansion is utilised in the secondary compressor. The two-stage compression also permits intercooling, which enhances the overall efficiency of the compression process. An ‘open system’ where the cold air is ejected directly into the cold space, removing the need for a heat exchanger in the cold space. In the interests of efficiency, the return air from the cold space is used to pre-cool the compressed air entering the turbine by means of a heat exchanger known as the ‘regenerator’ or the ‘recuperato ’. To support the design of the air-cycle demonstrator plant, and the selection of suitable components, a simple thermodynamic model of the air-cycle configuration shown in was developed. The compression and expansion processes were modelled using appropriate values of isentropic efficiency, as defined in heat exchange processes were modelled using values of heat exchanger effectiveness as defined in The model also made allowance for heat exchanger pressure drop. The system COP was determined from the ratio of the cooling power delivered to the power input to the primary compressor, as defined in illustrate air-cycle performance characteristics as determined from the thermodynamic model:illustrates the variation in air-cycle COP and expander outlet temperature over a range of cycle pressure ratios for a plant operating between −20 °C and +30 °C. The cycle pressure ratio is defined as the ratio of the maximum cycle pressure at secondary compressor outlet to the pressure at turbine outlet. For the ideal air-cycle, with no losses, the cycle COP increases with decreasing cycle pressure ratio and tends to infinity as the pressure ratio approaches unity. However, the introduction of real component efficiencies means that there is a definite peak value of COP that occurs at a certain pressure ratio for a particular cycle. However,illustrates, there is a broad range of pressure ratio and duty over which the system can be operated with only moderate variation of class of turbomachinery suitable for the demonstrator plant required speeds of around 50 000 rev/min. To simplify the mechanical arrangement and avoid the need for a high-speed electric motor, the two-stage compression system shown was adopted. The existing Thermo King SL200 chassis incorporated a substantial system of belts and pulleys to power circulation fans, which severely restricted the useful space available for mounting heat exchangers. A simple thermodynamic model was used to assess the influence of heat exchanger performance on the efficiency of the plant so that the best compromise could be developed show the impact of intercooler and aftercooler effectiveness and pressure loss on the COP of the proposed two-stage system in incorporated an intercooler between the two compression stages. By dispensing with the intercooler and its associated duct work a larger aftercooler could be accommodated with improved effectiveness and reduced pressure loss. Analysis suggested that the improved performance from a larger aftercooler could compensate for the loss of the the impact of the recuperator effectiveness on the COP of the plant, which is clearly more significant than that of the other heat exchangers. As well as boosting cycle efficiency, increased recuperator effectiveness also moves the peak COP to a lower overall system pressure ratio. The impact of pressure loss in the recuperator is the same as for the intercooler and aftercooler shown in. The model did not distinguish between pressure losses in different locations; it was only the sum of the pressure losses that was significant. Any pressure loss in connecting duct work and headers was also lumped together with the heat exchanger pressure loss and analysed as a block pressure specific cooling capacity of the air-cycle increases with system pressure ratio. Consequently, if a higher system pressure ratio was used the required cooling duty could be achieved with a smaller flow rate of air. shows the mass flow rate of air required to deliver 7,5 kW of cooling power for varying system pressure the demonstrator system was to be based on commercially available turbomachinery, it became important to choose a pressure ratio and flow rate that could be accommodated efficiently by some existing compressor and turbine rotors. and were based on efficiencies of 81 and 85% for compression and expansion, respectively. While such efficiencies are attainable with optimised designs, they would not be realised using compromised turbocharger components. For the design of the demonstrator plant efficiencies of 78 and 80% were assumed to be realistically attainable for compression and turbomachinery efficiencies corresponded to higher cycle pressure ratios and flow rates in order to achieve the target cooling duty. The cycle design point was also compromised to help heat exchanger performance. The pressure losses in duct work and heat exchangers increased in proportion with the square of flow velocity. Selecting a higher cycle pressure ratio corresponded to a lower mass flow rate and also increased density at inlet to the aftercooler heat exchanger. The combined effect was a decrease in the mean velocity in the heat exchanger, a decrease in the expected pressure losses in the heat exchanger and duct work, and an increase in the effectiveness of the heat exchanger. Consequently, a system pressure ratio higher than the value corresponding to peak COP was chosen in order to achieve acceptable heat exchanger performance within the available physical space. The below optimum performance of turbomachinery and heat exchanger components, coupled with excessive bearing losses, meant that the predicted COP of the overall system dropped to around 0,41. The system pressure ratio at the design point was 2,14 and the corresponding mass flow rate of air was 0,278 kg/ moving the design point beyond the pressure ratio for peak COP, it was anticipated that the demonstrator plant would yield good part-load performance since the COP would not fall as the pressure ratio was reduced. Also, operating at part-load corresponded to lower flow velocities and anticipated improvements in heat exchanger performance. Part-load operation was achieved by reducing the speed of the primary compressor, resulting in a decrease in both pressure and mass flow rate throughout the . Prime mover and primary compressorThe existing diesel engine was judged adequate to power the demonstrator plant. The standard engine was a four cylinder, water cooled diesel engine fitted with a centrifugal clutch and all necessary ancillaries and was controlled by a microprocessor the thermodynamic model, the pressure ratio for the primary compressor was 1,70. The centrifugal compressor required a shaft speed of around 55 000 rev/min. Other alternatives were evaluated for primary compression with the aim of obtaining a suitable device that operated at a lower speed. Other commercially available devices such as Roots blowers and rotary piston blowers were all excluded on the basis of poor one-off gearbox was designed and manufactured as part of the project to step-up the engine shaft speed to around 55 000 rev/min. The gearbox was a two stage, three shaft unit which mounted directly on the end of the diesel engine and was driven through the existing centrifugal . Cold air unitThe secondary compressor and the expansion turbine were mounted on the same shaft in a free rotating unit. The combination of the secondary compressor and the turbine was designated as the ‘Cold Air Unit’ (CAU). While the CAU was mechanically equivalent to a turbocharger, a standard turbocharger would not satisfy the aerodynamic requirements efficiently since the pressure ratios and inlet densities for both the compressor and the turbine were significantly different from any turbocharger installation. Consequently, both the secondary compressor and the turbine stage were specially chosen and developed to deliver suitable turbochargers use plain oil fed journal bearings, which are low-cost, reliable and provide effective damping of shaft vibrations. However, plain bearings dissipate a substantial amount of shaft power through viscous losses in the oil films. A plain bearing arrangement for the CAU was expected to absorb 2–3 kW of mechanical power, which represented around 25% of the anticipated turbine power. Also, the clearances in plain bearings require larger blade tip clearances for both the compressor and the turbine with a consequential efficiency penalty. Given the pressurised inlet to the secondary compressor, the limited thrust capacity of the plain bearing arrangement was also a concern. A CAU utilising high-speed ball bearings, or air bearings, was identified as a preferable arrangement to plain bearings. Benefits would include greatly reduced bearing power losses, reduced turbomachinery tip clearance losses and increased thrust load capacity. However, adequate resources were not available to design a special one-off high speed ball bearing system. Consequently, a standard turbocharger plain bearing system was secondary compressor stage was a standard turbocharger compressor selected for a pressure ratio of 1,264. Secondary compressor and turbine selection were linked because of the requirement to balance power and match the speed. Since most commercial turbines are sized for high temperature (and consequently low density) air at inlet, a special turbine stage was developed for the application. Cost considerations precluded the manufacture of a custom turbine rotor, so a commercially available rotor was used. The standard turbine rotor blade profile was substantially modified and vaned nozzles for turbine inlet were designed to match the modified rotor, in line with previous turbine investigations at QUB (Spence and Artt,). An exhaust diffuser was also incorporated into the turbine stage in order to improve turbine efficiency and to moderate the exhaust noise levels through reduced air velocity. The exhaust diffuser exited into a specially designed exhaust performance of the turbine stage was measured before the unit was incorporated into the complete demonstrator plant. The peak efficiency of the turbine was established at 81%.5. Heat exchangersDue to packaging constraints, the heat exchangers had to be specially designed with careful consideration being given to heat exchanger position and header geometry in an attempt to achieve the best performance from the heat exchangers. Tube and fin aluminium heat exchangers, similar to those used in automotive intercooler applications, were chosen primarily because they could be produced on a ‘one-off’ basis at a reasonable cost. There were other heat exchanger technologies available that would have yielded better performance from the available volume, but high one-off production costs precluded their use in the demonstrator different tube and fin heat exchangers were tested and used to validate a computational model. Once validated, the model was used to assess a wide range of possible heat exchanger configurations that could fit within the Thermo King SL200 chassis. Fitting the proposed heat exchangers within the existing chassis and around the mechanical drive system for the circulation fans, but while still achieving the necessary heat exchanger performance was very challenging. It was clear that potential heat exchanger performance was being sacrificed through the choice of tube and fin construction and by the constraints of the layout of the existing SL200 chassis. The final selection comprised two separate aftercooler units, while the single recuperator was a large, triple pass unit. Based on laboratory tests and the heat exchanger model, the anticipated effectiveness of both the recuperator and aftercooler units was 80%.6. InstrumentationA range of conventional pressure and temperature instrumentation was installed on the air-cycle demonstrator plant. Air temperature and pressure was logged at inlet and outlet from each heat exchanger, compressor and the turbine. The speed of the primary compressor was determined from the speed measurement on the diesel engine control unit, while the cold air unit was equipped with a magnetic speed counter. No air flow measurement was included on the demonstrator plant. Instead, the air flow rate was deduced from the previously obtained turbine performance map using the measurements of turbine pressure ratio and rotational . System testingDuring some preliminary tests a heat load was applied and the functionality of the demonstrator plant was established. Having assessed that it was capable of delivering approximately the required performance, the plant was transported to a Thermo King calorimeter test facility specifically for measuring the performance of transport refrigeration units. The calorimeter was ideally suited for accurately measuring the refrigeration capacity of the air-cycle demonstrator plant. The calorimeter was operated according to standard ARI 1100-2001; the absolute accuracy was better than 200W and all auxiliary instrumentation was calibrated against appropriate performance capacity of transport refrigeration units is generally rated at two operating conditions; 0 and −20 °C, and both at an ambient temperature of +30 °C. Along with the specified operating conditions of 0 and −20 °C, a further part-load condition at −20 °C was assessed. Considering that the air-cycle plant was only intended to demonstrate a concept and that there were concerns about the reliability of the gearbox and the cold air unit thrust bearing, it was decided to operate the plant only as long as was necessary to obtain stabilised measurements at each operating point. The demonstrator plant operated satisfactorily, allowing sufficient measurements to be obtained at each of the three operating conditions. The recorded performance is summarised .In total, the unit operated for approximately 3 h during the course of the various tests. While the demonstrator plant operated adequately to allow measurements, some smoke from the oil system breather suggested that the thrust bearing of the CAU was heavily overloaded and would fail, as had been anticipated at the design stage. Testing was concluded in case the bearing failed completely causing the destruction of the entire CAU. There was no evidence of any gearbox deterioration during . Discussion of measured performanceFrom the calorimeter performance measurements, the primary objective of the project had been achieved. A unique air-cycle refrigeration system had been developed within the same physical envelope as the existing Thermo King SL200 refrigeration unit, w

在我国现阶段中央空调系统的应用中，通常认为空调系统的温湿度控制以及空气品质的控制是最为重要的，进而忽略了空调系统的能源消耗情况。在我国，影响中央空调系统能源不能得到有效利用的主要因素有三方面，首先，在设计过程中重视投资成本，而忽略了能耗指标计算，在整个系统方案中，缺乏节能引导中央空调系统的经济性分析。导致在工程建筑方案的运行过程中，使用投资低、耗能大、运行费用高的空调系统。其次，对于中央空调而言，整个的系统工程相对复杂，所以对于中央空调能源有效利用的评价，要从整个系统全面来看，而不能单纯地停留在对机器设备本身的评价上，真正意义上的节能是与各个系统设计理念、施工优劣情况以及运行管理水平和建筑物热特性等因素息息相关，而不是只看重设备本身。最后，还有一个主要的因素，就是缺乏高素质运行管理人员和节能监控，致使空调系统在运行和管理的过程中没有得到很好地控制和监管，合格的管理人才可以大大改善运行不合理的地方，有利于节能。
建筑节能技术
空调系统的节能技术首先可以从建筑物本身入手，结合建筑、结构等相关知识，使建筑物在形状、色彩、方位及材料等方面为空调节能创造最基础的条件。对于空调位置的安排要进行合理布局，合理设计相关比例与系数，选择保温隔热性能良好的材料作为墙体和屋面，并提高改善建筑围护结构的性能等，都是建筑节能的可行性措施。
选择合理的室内设计参数
在整个建筑物中，主要的热损失来自于围护结构和门窗缝隙空气渗透。因此, 在建筑物进行建筑节能中，注重室内设计中加强围护结构，使用环保、节能型建筑材料, 可有效地减少通过围护结构的传热这一主要的空调负荷, 从而各主要设备的容量达到显著的节能效果。通过这种方法进行保温隔热，同时加强门窗的气密性。另外，在夏季空调供冷时，室内外侧玻璃受阳光照射，是空调冷负荷的主要部分，应采取必要的遮阳措施。而在冬季空调供热时，则要求改善窗户的保温效果，可以采用光热性能好的玻璃;为了减少窗的冷(热)桥传热，可以采用钢塑窗代替铝合金窗;同时还可以采用双层玻璃窗提高窗的保温性。在窗户的设计位置上要减小窗洞口与墙的面积比值减少空调房间两侧温差大的外墙面积及其薄弱环节窗的面积，利于空调建筑节能。
合理设计建筑结构
合理的设计建筑结构也是进行空调节能的一个有效途径之一。可以通过改善建筑的保温隔热性能，使房间内冷热量的损失通过房间的墙壁和门窗传递出去，这样可以有效地减少建筑物的冷热负荷。建筑物的朝向对空调冷负荷有很大的影响，根据我国的地理位置来分析确定良好的建筑朝向，一般建筑物为南朝向是我国建筑节能的必要条件，可以通过保持合理的建筑间距以及建筑群的错落布局，使建筑物接受适当的太阳辐射，同时有利于获得自然通风气流。
空调设计方面节能
在面积较大的空调房内，在空调房内区的负荷与周边区的相比较差距较大，如果两个区域选择使用一个空调系统进行制冷，两个空调房区域的房间的将会产生较大的温差，尤其是在冬季及过渡季节，所以同时处于两个不同区域的工作人员对环境空间的温度反映冷热温差较大，，根据我国在2001年版的《采暖通风与空气调节设计规范》新增条之规定,建筑物内负荷特性相差较大的内区与周边区,以及同一时间内必须分别进行加热与冷却的房间,宜分别设置空气调节系统.。内区系统主要处理室内负荷，与外区负荷相比，内区负荷则相对稳定，内区往往需要全年供冷，去除室内余热。外区系统主要处理外部得热，外区负荷波动大，外区新风来源一般是内区空调系统，与外区回风混合经风机盘管处理后达到送风点，外区冬季供暖，夏季供冷，从而满足舒适性要求。
空调系统中的节能技术
空调系统如何适应在低负荷下高效节能运行及在系统设计中对设备进行节能选配就成为空调节能的关键。
4. 1 加强中央空调的运行管理和控制设备的调节控制
提高空调能源的有效利用，需提高操控人员的职业素质，避免由于管理不善而引起的空调耗能。操控人员要做好设备运行记录，分析机组各种压力表、温度计、流量计的读数是否正常准确，并根据空调负荷的变化调节机组，确保机组运行在节能状态，而且定期保养检查，及时更换磨损的零件。
4. 2 设备及管道的保温及水质处理
要实现降低能量的过多耗费这一目标，就要做好设备及管道的保温。保温的目的是为了阻绝内外温度传递，如果室外的温度小于空调排水的温度加保温是为了防止空调水管结冰冻裂水管，如果环境温度大于空调排水温度加保温是为了防止有冷凝水造成漏水。空调设备和管道的保温，对于节省能量消耗、降低运行费用也是相当重要的。空调能耗高还有一个重要的原因，就是空调系统中水管中水质的污染。
5、建筑空调系统设备的节能运行技术
设备的节能运行技术在建筑空调系统综合节能技术中, 其也至关重要。主要技术包括: 蓄能空调技术、热回收技术、变频技术等。
蓄能空调技术
蓄能系统就是储蓄在不需要的冷/热量或需要的冷/热量减少的时间的过程中,制冷/热设备将蓄冷/热介质中所移出的热量，并在空调处于用冷/热或工艺性的用能高峰时，启动此能量。这样既减少了能源的流失，又可以有效地利用能源，既有经济效益又有社会效益, 是一项双赢的节能举措。
热回收技术
热回收技术包括排风余热回收和制冷机组的冷凝热回收。排风余热回收充分利用排风的能量, 对其进行回收，从而对新风进行预冷或预热,减小新风负荷是暖通空调节能的重要途径。制冷机组的冷凝热回收系统既可以避免冷凝热排放到大气中造成热污染, 又可以节省为提供热水而设的锅炉及其附属设备, 避免了由于燃料的燃烧向大气排放的有害物, 应该说是一种效果明显, 又有环保作用的节能技术。
变频技术
随着电力电子技术和计算机控制技术的不断发展，在空调控制系统中变频器也得到了广泛的应用，它的应用主要是针对空调控制系统的特点而进行控制。不同类型的冷水机组都有较完善的自动控制调节装置, 能随负荷变化自动调节运行状况, 保持高效率运行，从而实现了一种既能达到控制要求又能节约能源的方法。
太阳能空调技术
太阳能是绿色能源中最重要的能源, 太阳能的热利用是目前建筑中利用太阳能的主要利用形式。它包括被动式和主动式两种形式。被动式太阳能房的结构相对简单、造价低、不需要任何辅助能源, 通过建筑方位合理布置和建筑构件的恰当处理, 以自然热交换方式来利用太阳能。主动式太阳房结构较为复杂,造价较高,需要用电作为辅助能源。采暖降温系统由太阳集热器、风机、泵、散热器及储热器等组成。在建筑外围护结构中还可采用太阳能集热墙, 利用太阳能采暖。
6、结束语
能源问题是我国实现经济发展的重点问题之一，建筑空调节能技术是节约能源、改善环境、促进经济可持续发展的有效措施。空调系统在高负荷下高效节能运行以及在系统设计中选配节能设备是建筑空调节能的关键因素， 这对于节约能源、降低运行费用、促进国民经济发展具有十分重要的意义。在未来的建筑物中，在空调系统设计方面，要在节约能源以及有效利用能源这两方面引起高度重视。只要各方共同努力，空调系统的节能降耗问题的解决指日可待。
