Antifreeze Cooling&Heating Flow Control System

Antifreeze Cooling&Heating Flow Control System


  • Product Description
Temperature control range:-40 ° C ~ 135 ° C

Power range:7.5kw

Temperature control accuracy:±0.3°C

This equipment combines high and low temperature test chamber and antifreeze refrigeration heating flow system to provide high temperature and low temperature antifreeze and antifreeze flow and pressure control and 1000L high and low temperature test environment for new energy vehicle battery pack. The battery pack can be tested in a high environment, and the battery pack is provided with high temperature, low temperature, control flow, pressure, and the like. The temperature is -40 degrees to 130 degrees antifreeze temperature, antifreeze flow control 2~20L/min, and the environmental chamber provides -45 degrees to 100 degrees.

 The refrigeration unit mainly includes a refrigeration compressor, a condenser, an oil separator, an intermediate heat exchanger, an internal circulation fan of the tank, a drying filter, a condenser, an evaporator, a throttle mechanism, an expansion tank, and an electric control.

The system process flow is as follows:

The liquid refrigerant in the evaporator of the unit is exchanged with the circulating air in the interior of the tank. The temperature rises from liquid to gas, and is sucked into the suction port of the compressor. The high-temperature and high-pressure refrigerant gas after compression by the compressor passes through The oil separator separates the refrigerating machine oil carried in the compression process, and then enters the condenser, and exchanges heat with ambient air or cooling water to change from high temperature and high pressure gas to high pressure normal temperature liquid. The high-pressure normal temperature refrigerant liquid is dried by a filter and then throttled and depressurized by an expansion valve, that is, from a high-pressure liquid to a low-pressure liquid. The low-pressure liquid (lower boiling point) enters the evaporator of the unit, and the cooling air is brought to the inside of the tank by the circulating air to achieve refrigeration.

The anti-freeze solution is injected into the 80L pressure vessel, and the fully closed circulation system is adopted. This avoids the opportunity for the antifreeze to contact with the outside air and ensures the condensation of the water. After the expansion tank is protected by nitrogen, the temperature range of the heat transfer liquid is also broadened because its boiling point is increased. In addition, oxidation of the thermally conductive liquid in contact with oxygen in the environment is also avoided, thereby extending the useful life of the thermally conductive liquid.
