1. Ambient temperature: the ambient temperature outside the heat exchanger directly affects the evaporation or condensation temperature of the heat exchanger, directly determines the temperature difference inside and outside the heat exchanger tube, the greater the temperature difference of the heat exchanger, the greater the heat transfer capacity.
2. Environmental humidity: indoor wet bulb temperature during refrigeration has a great impact on the cold capacity, under normal circumstances, the higher the ambient humidity, the better the heat exchanger heat transfer effect.
3. Ventilation volume, wind speed: under normal circumstances, the greater the air volume, the higher the wind speed, the stronger the heat transfer capacity, the higher the heat transfer efficiency, but at the same time, the higher the noise generated, so it is necessary to reasonably determine the air volume according to the performance index requirements. Outdoor air volume selection also has the contradiction between heat transfer capacity and noise, in general, the windward area of single-row heat exchanger is relatively large, and the air volume is large.
4. Compressor capacity: the heat transfer capacity of the heat exchanger is proportional to the capacity of the compressor, the compressor displacement is large, the refrigerant in the system circulation is large, will speed up the flow rate of the refrigerant inside the heat exchanger tube, improve the heat transfer efficiency inside the tube. However, if the big horse car is used, the cost rises and the EER falls, which is a little more than worth the loss, generally not advocated, and only the heat exchanger is too small compensation.
