Temperature Control
Refrigeration Temperature Control
Many people mistakenly believe that cold refrigerated air escapes from the display case. Instead, ambient heat is actually drawn toward and disperses colder air, which causes an imbalance in the display case temperature inside. As more warm air rushes into the display case, this causes the temperature of stocked merchandise to warm up. The refrigeration and compressor system are now forced to work harder and more frequently to cool that air and to lower and stabilize cooler temperatures.
It’s not just heat that affects stocked merchandise in a refrigerated case. The infiltration of ambient light into the refrigeration cooler also causes variations in temperature and product appearance which is especially noticeable between the items merchandised at the front and those at the back of the display shelves. Most consumers can see the difference in food products at the front of the case; many items appear discolored and aren’t as chilled as those deeper into the case.
A refrigerated case full of products will show greater differences in temperature than an empty display case. Cold air does not flow as freely when blocked by stacks of food items within the case. In addition, the merchandise itself will hold the temperature of it surroundings; rear areas remain colder and the more exposed, open surfaces at the front of the case remain warmer.
Typically, frequent compressor operation and a certain level of product discard is tolerated to ensure the customer can shop freely.
