How Does The Ammonia Evaporator for Walk-in Cooler Work

The ammonia evaporator for a walk-in cooler works through the following steps:

Ammonia Inlet: Liquid ammonia is fed into the evaporator.

Heat Absorption: As the ammonia passes through the coils or tubes of the evaporator, it absorbs heat from the air inside the walk-in cooler. This causes the ammonia to change from a liquid to a vapor.

Cooling Effect: The absorption of heat results in a reduction of the air temperature within the cooler, creating the desired cool environment.

Vapor Exit: The vaporized ammonia exits the evaporator and is typically sent to a compressor or other components in the refrigeration cycle for further processing.

During this process, the design and configuration of the evaporator play a crucial role in ensuring efficient heat transfer. The surface area of the coils and the flow of ammonia are optimized to maximize the cooling capacity.

For example, in a food storage walk-in cooler, the ammonia evaporator continuously operates to maintain the low temperature required to keep the food fresh and safe. In a pharmaceutical storage application, precise temperature control is essential, and the evaporator works in tandem with other components of the refrigeration system to achieve this.
