For household air conditioner, evaporation temperature is, the higher the better
Right, is not only household air conditioner, air conditioning as well as other, evaporation temperature every once efficiency increased by 3%, but not the higher the better, if the evaporation temperature and condensation temperature difference is small, the unit is built not circulation, the unit can't work.
Not, proper temperature can improve the endothermic effect of refrigerant, when more than 5 ℃, can produce overheating, automatically adjust the air conditioning refrigerant flow, reduce the evaporation temperature. If the temperature is too high, it may be not enough refrigerant
No, high evaporation temperature, temperature is high, easy to cause the compressor overheating, high evaporation temperature on the user experience is not very good. Low evaporation temperature also cannot too low, the capacity of less than, can effect comparing to drop, and easy to cause leakage fault
Evaporation temperature is not higher, the better; At present for household air conditioner, the cost of each manufacturer pressure, at the same time due to the limited value of energy efficiency standards of the state is higher and higher, the pressure of improving energy efficiency is big; From the point of the compressor performance curve, within a certain range, the evaporation temperature rise will make the system have more ability to rise, but beyond this range, the evaporation temperature rise influence on the refrigerating capacity will become very not obvious; At the same time, the system of evaporation temperature rises, the indirect system of exhaust pressure rise, discharge temperature of compressor, suction temperature rise, so: in cost control, the refrigeration system running safe and controllable range, raise the evaporation temperature, is good for improving energy efficiency.
