The temperature of the evaporator of an industrial water chiller is under normal conditions, the outer surface of the evaporator is very cold, its condensation drops continuously, and the temperature of the inlet and outlet air is relatively large, usually Δt can be 12~14℃. Abnormal conditions, evaporation The surface of the device is not too cold, there is not much dew, or no condensation, the sound of refrigerant flowing is very loud, and the temperature difference between the inlet and outlet air is small.The reason is that the amount of refrigerant is insufficient, or the opening degree of the expansion valve is small. The relationship between the suction temperature and the exhaust temperature is the same. In fact, the exhaust temperature of the system has a close relationship with the suction temperature. As the suction temperature increases, the exhaust temperature also increases, and vice versa. To understand their relationship, you can master and control them well, and make the refrigeration system run better.
The ambient temperature requirements of the outdoor unit of industrial chillers are in accordance with national standards. When the ambient temperature of the outdoor unit is below 35℃, the air-conditioning unit should ensure normal operation and reach the cooling capacity and other indicators stated on the product nameplate. When the ambient temperature is within the range of 35~43℃, the air conditioning unit can operate, but the refrigeration capacity marked by its chrome brand cannot be guaranteed. It is already operating at full load. The condensing temperature, pressure, and exhaust temperature are all quite high. If the indoor unit has high heat, the electronic control protector may act, cut off the power supply, and stop running. When the outdoor temperature exceeds 43°C, the air conditioning unit is in overload operation, which will cause the action of the electronic control protection device to cut off the power supply and stop the operation. Indoor air-conditioning temperature requirements The highest normal indoor temperature value should not exceed 30°C. If the temperature exceeds 30℃, the air-conditioning unit may operate under overload conditions, and the condensing temperature and exhaust temperature of the refrigeration system will rise, which may also cause the electric protector to operate, cut off the power supply, and affect the operating life of the air-conditioning unit. unfavorable.
