The energy needed to keep a cold room at the defined temperature is calculated based on the size of the chamber and the inside and outside temperatures. After installation, there are, then, other energy inefficiencies that can increase the energy consumption of the cold room.

First, the design of the door is very important. Specifically, the factor influencing the energy efficiency is the type of door and the components used to build it. The use of poor-quality gaskets and profiles or components, like hinges and fasteners, that cannot guarantee the correct closure of the door can lead to significant inefficiency and increase in the energy consumption.

Another very important component is the pressure relief valve. On ...
