1、 With the decrease of volatilization temperature, the compression ratio of refrigeration compressor engine expands, and the energy consumption of production enterprises expands. When the volatilization temperature decreases by 1 ° C. It costs 3% to 4%. Therefore, reducing the volatilization temperature difference as much as possible and increasing the volatilization temperature can not only save energy, but also improve the air humidity of the cold chamber.
2、 With the increase of cooling temperature, the compression ratio of refrigeration compressor engine expands, and the energy consumption of enterprise air conditioning refrigeration capacity expands. The cold temperature is 25 ° C and 40 ° C for every 1 lift in the middle ° C，the power is increased by about 3.2%.
3、 When the heat transfer surface of the cooler and the evaporator of the air conditioner is covered with a layer of white edge filling liquid, the cooling temperature increases and the volatilization temperature decreases, resulting in the reduction of cooling capacity and the increase of power. When 0.1 mm thick white edge filling liquid is accumulated on the surface of the cooler, the cooling capacity of the refrigeration compressor will be reduced by 16.6 and the power will be increased by 12.4. When the crude oil is 0.1 mm thick inside the surface type air conditioning evaporator in order to maintain the predetermined ultra-low temperature requirements, the volatilization temperature is reduced by 2.5 ° C. Power up 9.7.
4、 When the steam is gathered in the cooler, the working pressure of the cooler will increase immediately. When the partial pressure circuit of non cooling gas reaches 1.96105pa, the power of refrigeration compressor must be increased by 18.
5、 When the operating scale of cooler wall is 1.5mm, the cooling temperature increases by 2.8 ℃ ° Before temperature calibration, the power was increased by 9.7.
6、 The surface layer of the evaporator is covered with frost, which reduces the thermal conductivity. In particular, the outer layer of finned tube radiator can not only improve the heat transfer friction resistance, but also reduce the gas flow in the middle of plate fin radiator. When the room temperature is less than 0 ° C. When the temperature difference between each other, air conditioning evaporator tube group 10 ° C. The thermal conductivity of evaporator of air conditioner is about 70 in one month before frost.
7、 However, if the temperature is too high, the specific capacity of the absorbed gas will be expanded, the refrigeration capacity of the air conditioner will be reduced, and the relative power will be expanded.
