现在许多冷冻式干燥器都配备有热气流旁通阀或所需要的控制电路。
Now many frozen type dryer are equipped with heat flow bypass valve or needed to control circuit.
配备有热气流旁通阀的冷冻式干燥器其冷冻剂压缩机不会频繁地开启和停机。
Equipped with heat flow bypass valve of freezing drying the coolant compressor is not frequently open and shut down.
热气流旁通阀通过将热冷冻剂与冷的冷冻剂混合，使空气-冷冻剂热交换器中的冷冻剂温度保持恒定。
Heat flow bypass valve through the heat and cold coolant of coolant mixed to make the air-freeze agent in the heat exchanger coolant temperature constant.
它由压缩机、冷凝器、节流阀或膨胀阀、蒸发器，以及一种工作流体(冷冻剂)组成。
It consists of a compressor, a condenser, a throttle or expansion valve, an evaporator, and a working fluid (refrigerant).
在这种情况下，需要紧密配合的阀来阻止夜间反向虹吸，以防止水在热交换器盘管中被冷冻。
In this case, tightly fitting dampers are required to prevent reverse thermosiphoning at night, which could freeze water in the heat exchanger coil.
