For the vast number of users, the power consumption of the chiller is a problem that the user is very concerned about. Many users are complaining that my unit is too expensive and the electricity is too high. So let's talk about why your chiller works so much.

 

 

 

The cooling capacity of Taizhou Cheng Shun refrigeration equipment is directly related to the operating conditions of the system. For the same structure, the speed and the type of refrigerant have been determined, the cooling capacity and energy consumption are changed as the operating conditions change and the operation management is different.

 

1. When the scale of the condenser wall reaches 1.5mm, the condensing temperature increases by 2.8 degrees and the power consumption increases by 9.7.

 

Two, the surface of the evaporator is covered with a layer of frost, which reduces the heat transfer coefficient, especially when the outer surface of the fin tube frosts, not only increases the heat transfer resistance, but also makes the air flow between the fins difficult, and reduces the heat transfer coefficient and the heat dissipation area of the surface. When the indoor temperature is below 0 C, when the temperature difference between the evaporator tube sides is 10 degrees, the heat transfer coefficient of the evaporator is about 70 before frosting for a month.

 

Three, the gas inhaled by the compressor allows a certain degree of overheat, but the overheat is too large, the specific volume of the inhaled gas is increased, the cooling capacity is reduced, and the relative power consumption is increased.

 

Four, shrink the machine to frost, quickly turn off the small suction valve, sharply reduce the cooling output, and increase the power consumption.

 

 

 

Five. With the decrease of evaporation temperature, the compression ratio of the compressor is increased and the energy consumption per unit cooling is increased. When the evaporation temperature decreases by 1 C, it will consume more power 3%-4%. Therefore, as far as possible to reduce evaporation temperature difference and increase evaporation temperature, not only can save electricity consumption, but also improve relative humidity of cold room.

 

Six. With the increase of condensing temperature, the compression ratio of compressor increases, and the energy consumption per unit cooling capacity increases. The condensing temperature is between 25 -40 and 1 degrees centigrade, and the power consumption is increased by about 3.2%.

 

Seven. When the heat exchange surface of the condenser and evaporator is covered with the oil layer, the condensing temperature will rise and the evaporation temperature decreases, which leads to the decrease of cooling capacity and the increase of electricity consumption. When a 0.1mm thick oil layer is deposited on the inner surface of the condenser, the cooling capacity of the compressor will be reduced by 16.6 and the power consumption is increased by 12.4. When the inner surface of the evaporator is oil deposited in the thick oil layer of 0.1mm, the evaporation temperature will decrease by 2.5, and the power consumption will increase by 9.7.

 

Eight, when the air is gathered in the condenser, it will cause the condensation pressure to increase. When the non condensing gas pressure reaches 1.96105Pa, the compressor power consumption will increase by 18.
