A cool room is a must-have for most restaurants and other commercial facilities, as the amount of food needed to keep such an establishment running cannot always be kept in refrigerators alone. A cool room also makes it easier to inventory and access everything you have on hand, since nothing is buried in deep shelves or out of sight. When a cool room in your facility stops working or doesn't seem to be maintaining a good temperature, there are a few things to check before you call for repairs. Note the following:
1. Blockages around the condenser coils
A cool room will usually have a main cooling unit outside your building, with a condenser that pulls moisture away from the housing. The coils of this condenser unit may be blocked with leaves or other debris, and in turn, air cannot circulate around the housing. This causes the motor and blower to work harder and prevents condensation from being removed from the unit. This stops the unit from producing colder air as it should.
If you notice debris building up consistently around the condenser coils then you might consider building a type of enclosure for the housing unit. You must ensure that there is adequate room for air circulation, but this can protect the unit and the temperature in your cool room.
2. The air filter
The air filter of your cool room not only keeps air clean but it also allows for an easier air flow from the housing to the cool room itself. By blocking out sediment and other debris, the motor and blower can push air through the vent or duct to the cool room. When the air filter gets clogged, the motor and blower both need to work harder. In turn, the cool room may not be getting as much cool air. Change the air filter regularly and check it when you notice a drop in temperature in your cool room.
3. The thermostat
This may seem obvious, but it's good to check the thermostat before you call for cool room repairs, as many restaurants keep the door to the room open and allow the plastic sheeting or curtains to insulate the room. When the temperature outside the cool room is very cool itself, the room may stay cooler naturally. As the temperature goes up during summer or when the kitchen is busiest, the cool room's own cooling needs to kick on more often to maintain its temperature. However, if the thermostat is not set properly, this won't happen. Check it first before calling for repair to ensure it's set to a reading that will keep the cool room functional no matter the outside temperature.
