What line is typically used to provide heat for evaporating condensate in many commercial reach-in boxes?

The discharge line is utilized to provide heat for evaporating condensate in many commercial reach-in boxes. When refrigerant gas returns to the compressor, it carries with it a significant amount of heat. This discharge line transports the hot refrigerant from the compressor to the condenser.

In the context of a reach-in box, the heat in the discharge line can be effectively used to warm the area around the evaporator and the condensate forms due to humidity within the unit. This warmth helps to evaporate any condensate that has collected in the drain pan, preventing overflow or potential issues with drainage. As a result, utilizing the discharge line for this purpose is an efficient way to manage moisture within the refrigeration system while ensuring optimal operation and reducing the risk of water accumulation that could lead to mold or other problems.

The other lines, such as the liquid line, suction line, and drain line, serve different functions in the refrigeration cycle and do not provide the necessary heat to evaporate condensate in the same way as the discharge line does.
