We often talk about the cooling capacity of the water-cooled chiller. In fact, the nominal cooling capacity of the industrial water-cooled chiller refers to a ambient temperature of 35 ° C, and the freezing water exit temperature is 7 ° C.

The amount of refrigeration is made. In actual operation, since the ambient temperature and the freezing export temperature are different, the capacity of the industrial water-cooled chiller and the power consumption of the compressor are also different.

Whether it is a ventilated chiller or a water-cooled chiller, the refrigeration amount increases as the temperature of the freezing water is increased, and as the environmental inlet air temperature is reduced.

Why does this happen? This is because the evaporation pressure of the corresponding industrial chiller is increased, the inhalation ratio is reduced, and the unit volume is refrigerated.

The amount of cooling capacity is increased; when the ambient temperature rises, the condensation pressure in the mechanical refrigeration system of industrial chiller has increased. Because the evaporation temperature is constant, inhalation is comparable

It is also unchanged, the air blower compressor is lowered, and the unit quality refrigeration is reduced. Therefore, the cooling capacity of industrial chillers is also reduced.

The power consumption of industrial water-cooled chillers increases with the increase in the increase in the temperature of the frozen water and an increase in ambient temperature. This is because when the freezing water temperature of the chiller rises,

The evaporation pressure increases. If the ambient temperature does not change (that is, the condensation pressure is unchanged), the compression ratio will decrease, and the power consumption will be reduced, however, industrial cold water at this time

The machine requires more power to increase the refrigeration, so the total power consumption of the compressor will still increase.

If the ambient temperature rises, the condensed pressure is increased, and the freezing water exit temperature (evaporation pressure) of the industrial chiller remains unchanged. At this time, the compression ratio is increased.

Increased. Then the power required for the reduction in the reduction in the refrigeration is slightly reduced, the total power consumption of the compressor is also increasing.
