Most places where dehumidifiers are used are relatively humid or places with strict requirements on air humidity, so dehumidifiers are needed to reduce the moisture content in the ambient air. It can be seen that the dehumidifier occupies an important position, but due to the aging or improper use of the equipment, various failures also occur from time to time. The most annoying thing should be the ice blockage of the dehumidifier. I wonder if you have a good way to share it.
How to judge whether a dehumidifier has an ice blockage failure, the best way is to observe its dehumidification effect. If the effect deteriorates or does not dehumidify at all, the problem exists. The reason for this failure is mainly due to the setting of the dehumidifier refrigeration system pipeline. Since the joint between the capillary and the evaporator is a small pipe connected to a large pipe, it is easy to generate pressure reduction and expansion, and eventually cause the moisture to be frozen into ice and blocked. .
If you encounter similar problems, don’t be irritable. First, clean up all the refrigerants with high water content in the refrigeration system of the dehumidifier, and then pour nitrogen into the system and make it in a vacuum state. At this time, add an appropriate amount of refrigerant to run for a period of time, wait until the vacuum degree reaches the requirement and then charge the refrigerant again.
