Detailed Description

Direct cooling type low temperature refrigeration equipment

The refrigerant in the refrigeration system is directly output and evaporated into the target control element (heat exchanger) for heat exchange, thereby cooling the target control object. The heat exchange capacity is generally more than 5 times higher than the heat exchange capacity of the fluid (gas) transported into the heat exchanger. This is especially suitable for applications where the heat exchange area of the heat exchanger is small but the heat exchange capacity is large. It can also be used as a gas trap. The refrigerant is directly passed into the trap to evaporate, and the gas in the space can be quickly trapped through the condensation effect of the trap surface.
