For central air conditioning in use for some time after the effect of heat transfer will be decreased, the problem of increased power consumption (energy increase is due to lack of wear lubricants within the compressor, heat exchanger pipe wall thickness of the film to form a different, lower a heat exchanger thermal efficiency, leading to a decline in air temperature, increase in electricity use. refrigeration system has 0.1mm thick film, 11-12% increase in energy consumption, according to the duration of the use of equipment, equipment performance generally decreased by 10 % -30%) with central air-conditioning energy-saving agent (PROA) add air conditioning, you can reduce air conditioning energy consumption, reduce carbon emissions and help businesses reduce the power consumption of air conditioning and other refrigeration equipment, energy saving and business together to complete the task. 
 Agents referred to as central air-conditioning energy PROA, is used to improve the energy efficiency of new refrigeration system energy-saving products, which can effectively reduce the air conditioning and refrigeration equipment, power consumption of 8% -30%, increase the air temperature. Central air-conditioning energy saving agent additive (PROA) to energy-saving mechanism of action is: Clear refrigeration oil film on the surface of the metal wall, forming a layer of PROA molecular layer of protection, to improve lubrication and reduce wear and increase the heat transfer efficiency of heat exchange system, to achieve the 8% -30% power saving purpose. 
 PROA features and performance characteristics: 
 Reduce power consumption - can reduce the power consumption of 8% -30% equipment; 
 Reduce the outlet temperature - reduce the outlet temperature of 2-6 degrees; 
 To reduce mechanical friction - moving parts in the compressor attached to the surface layer of PROA molecular layer of protection, and has reduced mechanical friction between the parts; 
 Extend equipment life - Reduced mechanical friction, a reasonable extension of equipment life. 
 Lower operating noise - reducing mechanical friction, reduce equipment operating noise. 
 Suitable for: 
 Various types of air conditioners, heat pumps, refrigeration equipment, chillers, reciprocating piston compressors, rotary compressors, screw and centrifugal compressors, ammonia refrigeration systems, energy-efficient freezer chlor-alkali plant.
