How Does Glycol Evaporator Work?

A glycol evaporator, often used in refrigeration systems, is a device that utilizes the evaporation of glycol (usually ethylene glycol or propylene glycol) to cool a surrounding area.

How it Works:

Heat Absorption: Glycol evaporators work on the principle of heat absorption during the phase change from liquid to vapor. When the glycol evaporates, it absorbs heat from its surroundings, thus cooling the area.

Heat Transfer: The glycol evaporator is connected to a refrigeration system. A refrigerant, such as ammonia or a synthetic refrigerant like R-134a, circulates through the evaporator coils. This refrigerant is at a low pressure and temperature.

Evaporation: The glycol flows over or through the evaporator coils. As the glycol comes into contact with the cold coils, it evaporates, absorbing heat from the environment.

Cooling Effect: The evaporation of the glycol causes a cooling effect in the area around the evaporator. This can be used for various purposes such as air conditioning, refrigeration, or maintaining specific temperatures in industrial processes.
