Description

Technical Field

[0001] This utility model relates to the technical field of refrigerant drying equipment, and belongs to an adjustable refrigerant dehydration device. Background Technology

[0002] In the stable operation of a refrigeration system, the purity of the refrigerant is crucial, with moisture content being a key factor affecting refrigeration performance and equipment lifespan. When the refrigerant contains moisture, it easily freezes during the low-temperature phase of the refrigeration cycle, leading to ice blockage. This hinders the normal flow of refrigerant, reducing refrigeration efficiency and, in severe cases, even causing the entire refrigeration system to fail. Furthermore, moisture can react chemically with the refrigerant and metal components in the refrigeration system, accelerating metal corrosion and significantly shortening the equipment's lifespan.

[0003] Traditional refrigerant dehydration equipment generally has some problems. The equipment cannot be adjusted and used. When it is necessary to replace the dehydrating agent, adsorbent, or other reagents, the machine must be stopped and waited for the old and new adsorbents to be replaced and refilled. The equipment also needs to be reinstalled before the drying process can be carried out again. This process is time-consuming, lacks flexibility, has low dehydration efficiency, and places a heavy workload on the staff. Utility Model Content
