If you have just purchased a building which you plan to turn into a restaurant, it is likely that you will want to install a cool room so you can keep meat fresh until it is ready to be cooked and served. However, because a cool room must be maintained at a steady temperature using a system of fans and refrigeration units, they can consume a lot of power. Thankfully, there are some steps you can take which will help you make your new cool room energy efficient.
Periodically inspect the door gaskets
A gasket is a soft rubber strip that runs around the edge of a door. When the door is shut and locked into place, the rubber strip is compressed between the door and the frame, forming an airtight seal which prevents warm air from entering the cool room or cold air escaping. However, with use, the gaskets on your door may become brittle, and this can cause cracks to appear on the plastic surface. The cracks prevent the gasket from forming an airtight seal, which means your refrigeration and fan units will need to be used more often to keep the cool room at a steady temperature and will, therefore, use more energy. You should periodically check the condition of the rubber gasket on your cool room door. If you see any signs of damage, you should have the gasket replaced.
Clean the refrigeration coils
The refrigeration unit in a cool room works by absorbing heat from the air inside the cool room using evaporation coils. These metal coils are filled with coolant. As the coolant evaporates, the coil draws heat from the air into the coil via the process of heat exchange. However, if the coils within your refrigeration unit become covered in dust or grime, this can affect the coils ability to absorb heat and will result in the unit using a lot more electricity as it attempts to keep the space cool.
Consider the airflow
In order to properly cool a space, a refrigeration unit needs the air inside it to flow around. With cool air which is blown out of the refrigeration unit flowing along the lower level of the room before it warms slightly and is carried back along the ceiling where it reenters the unit and is cooled again. However, if you place floor to ceiling shelves or stacks of boxes in your cool room, you may disrupt the airflow and the cooling and warming cycle, leading to hotspots and increased energy consumption. To prevent this problem, you should always ensure that air can move freely around whatever you are storing in your cool room.
