Hot Freezers

  1. Mar 15, 2009 #1
    This isn't really in the usual thread of these forums but physics is what I need to provide the answers and I don't have a good enough grounding in the topic.

    Here is my problem:

    I have a storeroom that is about 5 x 2.5 x 4 m. At night it is locked up for around 12 hours duration. Inside the storeroom there is no proper ventilation. Beyond the cracks beneath and above the door and a blocked air condition vent (only adds a one meter cube of space to the room) it is a sealed room. Inside the room I have five fridges/freezers: one chest freezer, two double door freezers (2 x 2 x 1 m) and two double door fridges (2 x 1.5 x 1 m). When I walk in in the morning the air temp is usually pushing 50 C. And the freezer is usually hovering at or above 0 C. During the day, the door is kept open and everything operates normally.

    My question is this: Is it the hot air being pumped from the freezers/fridges that is causing the freezer to fail?

    If so, will installing an air con for use overnight fix this without proper vents?

    Thanks for any help.

    It is the hot air causing the problem. An air conditioner would work, but putting a vent in the door and running an exhaust fan at the air conditioner vent would probably work as well. In winter, the fan could blow cold outside air in.
