Why Do You Need Preair LGR Dehumidifiers

The deep supercooling patent solves the shortcomings of non-LGR dehumidifiers with poor dehumidification effect under low humidity conditions. The disadvantage of the traditional non-LGR dehumidifier is that the refrigerant liquid at the end of the condenser is insufficient "undercooling", the refrigerant liquid temperature is much higher than the refrigerant evaporation temperature in the evaporator, and a small amount of refrigerant evaporates and vaporizes in advance before entering the evaporator, resulting in a decrease in dehumidification capacity.

("DEEP SUPERCOOL" Patent)

The deep supercooling technology patent improves the supercooling degree of the refrigerant liquid at the end of the condenser by reducing the temperature of the refrigerant at the end of the condenser, which is conducive to reducing the gasification ratio of the refrigerant liquid in the throttling device, ensuring the integrity and effectiveness of the evaporation heat absorption capacity of the refrigerant in the evaporator, to improve the evaporation heat absorption capacity and dehumidification capacity of the evaporator.

By supercooling the air, the dehumidifier can extract even more moisture before it reaches the dew point and condenses. This allows for more efficient dehumidification, especially in environments with extremely high humidity levels. It’s a more advanced and precise technique compared to standard refrigerative dehumidification.
