Dehumidifier tests

• Intake air filter that traps solids contaminating the dried air;
• Air cooler, designed to reduce the temperature of the incoming humid air to a temperature enabling condensation of a significant part of the moisture;
• A condenser, in which the cooling air stream in the evaporator is heated to approximately the initial temperature;
• A suction fan, which forces a constant flow of ambient air to the dryer, and after the above-mentioned devices pass, forwards the air through the perforated front wall of the dryer into the environment, with a certain part of the air stream being used to cool the compressor compartment and the electric unit of the dryer before leaving the dryer;
• Compressor, which is the basic element of the closed refrigeration circuit. Its task is to maintain the correct pressure levels in the evaporator (low pressure side) and in the condenser (high pressure side) and ensure the required refrigerant flow rate in the circuit;
• The expansion element, typically a capillary, provides expansion of the high-pressure liquid refrigerant flowing from the condenser to the vapor pressure of the air cooler.

In addition, the cooling circuit is equipped with a filter-dehydrator, whose task is to remove impurities and moisture from the liquid refrigerant, which appear during operation.

Refrigeration R&D Center has been cooperating with domestic producers of dehumidifiers, participating for many years, including in research and development carried out by these companies in the field of the devices in question
