The theory of gas transmission capacity compressor is constant, the increase in suction specific volume will cause the compressor to reduce the quality of gas inhalation, the actual gas compressor reduced,[link widoczny dla zalogowanych], thus reducing the compressor cooling capacity, meaning that if the compression machine or technology exchange in accordance with the temperature of a 1l ℃, 37 ℃ low temperature for a matching, then probably not enough, we must consider the temperature of 1 ℃ loss has been changed from the 2clC, matching the compressor to be in accordance with a l2 ℃ and 38 ℃ for a the evaporation temperature to choose, the choice will be compared to the original increase. The resulting increase in compressor capacity increase can be way too cold to be compensated by the consumption of supercooled liquid cooling load temperature refrigeration system Central, the temperature of the system unit in a relatively low temperature system, much greater energy efficiency, which added from high to low is the economy. 3 Conclusion of engineering materials in the matching diameter when the pressure loss by the standard extended to 2 ℃ 1 ℃ can save a lot of engineering materials, up to 20%, and the resulting capacity increase by increasing the compressor off cooler approach to compensation.
