Compressor cooling system the highest technical content, most difficult and most complex the production process critical components, is the heart of the refrigerationsystem, compressor quality will have a direct impact on the refrigeration system is good or bad. In turn, the refrigeration system design and matching quality determines the compressor working.

Seven directions to enhance energy efficiency

Energy consumption of air conditioner parts are: compressor, the indoor fan, outdoor fans, wind direction motors, control systems, standby power consumption. With the exception of standby power consumption is not in the standard range of international standards at home and abroad, is the major energy-consuming air conditionercompressor components, accounted for more than 88% of total energy consumption. Therefore, the compressor efficiency will directly result in the improvement of air conditioner efficiency.

In theory, any measures that can reduce the loss of compressor to increase the efficiency of the compressor. The key question is whether the measures taken by the main loss is for the compressor. More difficult is that different types of compressors, compressor main losses are different from different manufacturers. Therefore, in order to improve the efficiency of the compressor the compressor must be specific to have a deep understanding and awareness, which means a lot of basic technical work, but also the compressor business weaknesses.

Here only in a general sense to analyze the measures to improve the efficiency of the compressor. First, improved motor efficiency, motor efficiency of improve means with compressor electric efficiency of improve and compressor general efficiency of improve; second, reduced friction power, reduced friction power means with mechanical efficiency of improve; third, improved valve, valve movement law of right or not, and spring force and air thrust of reasonable match, and structure parameter of optimization, and flow resistance of reduced, and for valve caused of more than gap volume of control, any aspects of improved are can improve compressor of efficiency; IV, reduced sucking, and Discharge pressure pressure pulsation losses and last, raise the temperature coefficient, last, improved volume coefficient; seven, reduce leakage, increase the leakage coefficient.

Variable condition performance of the most important

No doubt, improve the energy efficiency of compressors will directly bring energy-saving air conditioners. Due to the compressor as the main energy-consuming components, so this will be the most effective means of saving energy. Rely mainly on technological improvements and better efficiency and compressor is not a significant increase in consumption of materials, this is the best technical and economic meansof saving energy.

However, is in need of attention, the energy efficiency of the compressor in order tomeasure, compare, is unified under the operating conditions of a specific determination. Compressor manufacturer in order to obtain higher energy efficiency evaluation, design efficient compressor is for this specific condition. In performance testing, the air conditioner, compressor operating mode is often not their design operating conditions, and that working conditions for various air conditioner design changes. Further, air conditioners in actual working conditions nor air conditioner test conditions, nor the design conditions of the compressor, it will use the environment ambient temperature the indoor temperature changes and user.

Compressor run time rather than design conditions for energy efficiency energy efficiency than there have been two levels of variables: specific design of air conditioner (depending on air conditioner manufacturer) and use of the environment. Then simply the pursuit of efficiency of the compressor under the design conditions loses the significance of energy conservation.

This compressor variable condition performance concept: compressor energy efficiency should be maintained in a broad range of higher when running in the air conditioner will be able to get a good energy-saving effect.

Air conditioning machine decides the compressor conditions

From the perspective of design of air conditioners, high efficiency compressor may improve the efficiency of the air conditioner. But improvement is not totally dependent on the compressor of air conditioner efficiency. In other words, you can use lower-efficiency compressors developed high efficiency air conditioner, with an efficientcompressor will produce inefficient air conditioners. All depends on the air conditioner according to national standard test conditions test the actual operation conditions of the compressor.

Some air conditioner manufacturers use high efficiency compressors, small heat exchanger manufacturing inefficient air conditioners to cut costs is the truth. At this time due to the large heat temperature compressor discharge pressure of high and lowsuction pressure, therefore the compressor pressure ratio is large, lower cooling capacity and efficiency is lower. Development of high efficiency heat exchanger of air conditioner needs to increase.

So, from air conditioner of design angle see, to improve air conditioner of efficiency contains two a aspects: while is in national standards provides of, and fixed of test workers condition Xia design air conditioner Shi makes air conditioner has high of efficiency, which contains with full play compressor of refrigeration capacity and efficient of meaning; on the is is air conditioner variable workers condition run of concept: air conditioner should in more broad of range within keep high of energy efficiency, such in air conditioner actual run Shi only can get good of energy-saving effect.
