How To Solve The Electric Vehicle Motor Test Condensation Is Too High?
The condensing pressure of the electric vehicle motor test will increase, the compression function will increase, the cooling capacity will decrease, the cooling coefficient will decrease, and the energy consumption will increase. The reason for the rise of the condenser pressure may be that the condenser is too small. It is recommended to replace or increase the condensation. If the flow of cooling water is insufficient, it is recommended to increase the number of pumps running and increase ...

Effect Of Humidity On Laboratory Chillers
The high humidity reduces the insulation strength of the electrical equipment of the chiller in the laboratory. The moisture in the air adheres to the surface of the insulating material to form condensation, which reduces the insulation resistance of the electrical equipment, and the leakage current of the equipment is greatly increased, resulting in insulation breakdown. Condensation inside the switchgear causes creepage and flashover accidents, resulting in electrical faults. If the air is ...

Details anzeigenRelationship Between Poor Refrigeration Performance And Refrigerant In Low Temperature Industrial
The effect of the refrigeration system of the low-temperature industrial refrigerator is directly related to the refrigerant. Once the refrigerant leaks, the cooling capacity will be insufficient, so that the suction and exhaust pressures are relatively low, and the expansion valve and the evaporator are in operation. The balance pressure cannot be maintained. Therefore, if the refrigerant leaks from the low-temperature industrial refrigerator (group) is found, it is not rushed to fill the sy...
