How Does A Commercial Refrigeration System Maintain Cold Temperatures?

A commercial refrigeration system is designed to maintain cold temperatures in commercial settings such as restaurants, grocery stores, and warehouses. The system typically consists of a refrigeration unit, a condensing unit, an expansion valve, and an evaporator coil.

The refrigeration unit contains the evaporator coil, a fan, and a refrigerant. The fan blows air over the evaporator coil, which cools the air as it passes over the coil. The refrigerant absorbs the heat from the air, causing it to cool.

The condensing unit contains the condenser coil, a fan, and a compressor. The condenser coil releases the heat absorbed by the refrigerant, causing it to condense into a liquid. The fan blows air over the condenser coil, which cools the liquid as it passes over the coil.

The expansion valve regulates the flow of refrigerant into the evaporator coil. As the refrigerant expands, it absorbs heat from the air, causing it to cool.

The evaporator coil contains the refrigerant, which absorbs heat from the air, causing it to cool.

By continuously circulating the air over the evaporator coil, the refrigeration system removes heat from the space, causing the temperatures to drop. The condensing unit then releases the heat absorbed by the refrigerant, causing the temperatures to rise.

The refrigeration system also relies on the use of insulation to prevent heat from entering the space. This insulation is typically in the form of foam panels or spray-on insulation.

Overall, a commercial refrigeration system relies on a combination of refrigerant, fans, compressors, expansion valves, and insulation to maintain cold temperatures.
