Friends, do you want to know why your freezer consumes so much power?
The cooling capacity of the chiller is directly related to the operating conditions of the system. Therefore, the operation of the freezer is a very important part of industrial refrigeration. Reducing the energy consumption of the freezer can help companies reduce production costs and improve economic benefits, which is a very important thing. If you want to reduce the energy consumption of your freezer, you need to know why your freezer consumes so much power.
The power consumption of industrial refrigerators is affected by many factors. What are the specific ones? Below, let us take a look at the editor of Jincheng industrial refrigerator manufacturer.
1. As the evaporation temperature decreases, the compression ratio of the compressor increases, and the energy consumption per unit of production cooling increases. When the evaporation temperature drops by 1°C, it consumes 3% to 4%. Therefore, minimize the evaporation temperature difference of the refrigerator and increase the evaporation temperature, which not only saves energy, but also increases the relative humidity of the cold room.
2. As the condensing temperature increases, the compressor compression ratio increases, and the energy consumption per unit of refrigeration capacity increases. When the condensing temperature is between 25°C and 40°C, for every 1°C increase, the power consumption increases by about 3.2%.
3. When the heat exchange surface of the condenser and the evaporator is covered with an oil layer, the condensation temperature increases and the evaporation temperature decreases, resulting in a decrease in cooling capacity and an increase in power consumption. When a 0.1mm thick oil layer accumulates on the surface of the condenser, the cooling capacity of the compressor will be reduced by 16.6 and the power consumption will be increased by 12.4. When the oil is a 0.1mm thick inner surface type evaporator, in order to maintain the predetermined low temperature requirement, the evaporation temperature is reduced by 2.5°C and the power consumption is increased by 9.7.
4. When air accumulates in the condenser, the pressure of the condenser will increase. When the partial pressure of non-condensable gas reaches 1.96105Pa, the power consumption of the compressor needs to increase by 18.
5. When the scale of the condenser wall reaches 1.5 mm, the condensing temperature rises by 2.8°C before the temperature calibration, and the power consumption increases by 9.7.
6. The surface of the evaporator is covered with a layer of frost, which reduces the heat transfer coefficient. Especially the outer surface of the fin tube is frosted, which not only increases the heat exchange resistance, but also makes the air flow between the fins difficult and reduces the appearance. Heat transfer coefficient and heat dissipation area. When the indoor temperature is lower than 0°C, when the temperature difference between the two sides of the evaporator tube group is 10°C, the heat transfer coefficient of the evaporator is about 70 after working for a month before frosting.
7. The gas sucked by the compressor allows a certain degree of overheating, but if the overheating is too large, the specific volume of the sucked gas increases, the cooling capacity decreases, and the relative refrigerator power consumption increases.
8. When compressing the frost, quickly close the small suction valve to drastically reduce the cooling capacity and relatively increase the power consumption.
The refrigeration capacity of the refrigerator is directly related to the operating conditions of the system.
