Humidity control in supermarkets

A supermarket is a large retail market that sells food and other household items, usually operated in a self-service manner

The impact of uncontrolled humidity

Supermarkets face unique and diverse conditions while meeting the diverse needs of different departments under the same ceiling. These issues are high humidity, temperature control, personnel movement, and fresh air.

If the humidity level in the supermarket is too high, the main problem is the condensation of moisture on the cold surface and frost on the evaporator coils/refrigerated boxes/frozen food packages, leading to customer loss.

Moreover, the condensate on the glass cabinet of the freezer obstructs the view, making it difficult for customers to choose frozen food.

High humidity levels can lead to mold problems and uncomfortable environments for customers and employees.

Reasons for uncontrolled humidity

Supermarkets witness high humidity

A large amount of human movement requires fresh air to neutralize high levels of CO2, which is the main source of moisture.

There is a large amount of organic matter (fruits and vegetables) that releases moisture from the atmosphere.

General recommendations

The ideal storage should be maintained at a dew point of 12 ° C and a relative humidity of 45-50% RH. Desiccant dehumidification helps supermarkets eliminate frost buildup on frozen food, freezers, and cabinet doors. This process significantly reduces the power consumption of traditional refrigeration to offset potential loads while providing a more comfortable shopping environment.

Dehumidifier solution

Desiccant+refrigeration unit dehumidifier to meet all the needs of supermarkets. When using desiccant based dehumidifiers, the incoming fresh air should be dehumidified at a temperature that can maintain a dew point of 12 ° C after being mixed with the return air from the internal area.
