How does an LGR dehumidifier enhance efficiency?

An LGR (Low Grain Refrigerant) dehumidifier enhances efficiency primarily by pre-cooling air before it interacts with the coils. This process allows for increased condensation efficiency on the evaporator coils. When the warm, humid air is cooled before it hits the coils, the relative humidity of that air increases, enabling the dehumidifier to extract more moisture from the air more effectively.

This approach is crucial because it maximizes the dehumidification process. The colder air can hold less moisture before it condenses, allowing for a more efficient extraction of water vapor. The pre-cooling function effectively reduces the load on the dehumidifier, allowing it to operate at a lower temperature while still achieving high moisture removal rates. This results in better overall performance and energy efficiency as more moisture is removed in a shorter period.

This operational principle stands in contrast to other methods, which may not take advantage of pre-cooling, leading to less effective moisture extraction.
