The reason for the abnormal power consumption of small cold water machines in air-cooled industrial industries

The cooling capacity of air-cooled industrial small chillers is directly related to the operation of the system.
compressors of the same structure, the same speed, the same refrigerant type, their operation management is different and changes due to changes in operating conditions, cooling capacity and energy consumption.
the next step is to chat with the editor about the factors that lead to abnormal power consumption of the chiller! First, with the decrease of evaporation temperature, the compression ratio of the compressor increases, and the energy consumption per unit of production cooling increases.
, the evaporation temperature difference is minimized, the evaporation temperature is increased, and the relative humidity of the cold room is increased.
, with the increase of condensation temperature, compressor compression ratio increased, energy consumption per unit of cooling capacity increased.
, when the heat exchange surface of the condenser and evaporator covers a layer of oil, the condensation temperature increases and the evaporation temperature decreases, resulting in a decrease in cooling capacity and an increase in power consumption.
, when air gathers in the condenser, the pressure of the condenser increases.
, the surface of the evaporator is covered with a layer of frost, reducing the heat transmission coefficient.
, especially the outer surface of the fin tube, not only increases the heat exchange resistance, but also makes the air flow between the fins difficult and reduces the appearance.
, the compressor inhaled gas allows a certain degree of overheating, but overheating is too large, the ratio of inhaled gas volume increased, cooling capacity decreased, relative power consumption increased.
, compression opportunity cream, quickly close the small suction valve, sharply reduce the amount of cooling, and relatively increase power consumption.
