When the weather temperature rises, will the compressor exhaust temperature rise?

Many customers don't know why the exhaust of screw air compressor is overheated. Overheating of screw air compressor is a serious danger. I hope this article can help us. The main reasons of exhaust temperature overheating are: high return air temperature, large heat capacity of motor, high compression ratio, high condensation pressure and improper selection of refrigerant. Exhaust overheating is not so messy, but for these reasons: the return air temperature is high; The return air temperature inhomogeneity is related to evaporation temperature. In order to prevent liquid from flowing back, the superheat of return air is required to be 20℃ in general return air pipeline. Assuming that the air return pipe is not well insulated, the superheat will far exceed 20℃. The higher the return air temperature, the higher the cylinder suction temperature and exhaust temperature. When the return air temperature increases by 65438 0℃, the exhaust air temperature will increase by 65438 0 ~ 65438 0.3℃. Electric heating: With regard to the screw air compressor with back air cooling, the refrigerant vapor is heated by the motor when it flows through the motor cavity, and the suction temperature of the cylinder trudges again. The calorific value of motor is influenced by power and power, and power consumption is closely related to displacement, volumetric power, working condition and friction resistance. In the semi-sealed screw air compressor with return air cooling, the temperature rise planning of refrigerant in the motor cavity is roughly between 15 ~ 45℃. In the air-cooled (air-cooled) screw air compressor, refrigeration does not pass through the winding, so there is no motor heating problem.
