Under normal conditions, what does a medium temperature room using ammonia (NH3) refer to?

A medium temperature room using ammonia (NH3) generally pertains to the operating conditions for refrigeration within a specific temperature range that is not too cold or too warm. In industrial refrigeration systems, ammonia serves as a refrigerant due to its efficient heat absorption properties at various temperatures.

In this context, the term "medium temperature" typically refers to a temperature range commonly used for storing perishable goods like dairy products, fruits, and certain meats, which usually falls between 28°F to 50°F (-2°C to 10°C). This definition allows users to understand that the room is intended for refrigeration purposes rather than freezing or processing.

Since medium temperature rooms must sustain these conditions effectively to maintain the quality and safety of stored products, it directly aligns with the concept of operating conditions for refrigeration, emphasizing how ammonia is applied within this temperature range to achieve optimal refrigeration performance.
