Humidity is perhaps the most significant challenge confronting Open-Air Refrigeration. It doesn’t emphasize taking much for moisture infiltration to contrarily influence the cold space using condensation, slip hazards, or unreasonable coil freezing.
This harmful build-up of moisture can cause significantly more pressing issue in cold storage than it would in dry storage because of the tightness of the building envelope.
How could humidity be controlled in a commercial refrigeration unit?
Perhaps the most well-known method of bringing down humidity is permitting the coils to freeze then sending them into defrost to remove the water. In any case, this strategy has huge disadvantages such as higher utility bills, wear and tear on the refrigeration unit, and temperature spikes. There is also the risk that it does not remove enough water to be effective.
The most efficient approach to battle high humidity in freezers or even in cold chain units is the usage of a desiccant dehumidifier.
Moisture infiltrates through the dock doors, propane fork trucks, leaks, human tenants, washdowns, or the products can cause damage to the structure, refrigeration system, or building substance. Using a dehumidifier will keep the humidity level noticeable all-around at a steady level based on your preference, which implies you will not manage high relative humidity.
Other ways to control humidity in commercial refrigeration units
While a dehumidifier is an ideal approach to battle humidity in freezers and cold chain units, it should be used related to a couple of other accepted procedures. For instance, rapid doors, vapor barriers, vinyl curtains, and air curtains are crucial to guarantee that moisture invasion is restricted. Consistently a way to the outside stays open; humidity is rushing into the conditioned space.
Notwithstanding ordinary support, commercial refrigeration maintenance, and service, cold chain unit needs to have excellent seals on all doors and panels. Without a solid seal, moisture can invade the unit and cause high humidity levels.
A unit coming up short on a good seal is similar to leaving your front door open. Replacing old, broken seals and keeping a good quality seal can go far to keep the unit as productive and financially savvy as could be expected.
How does the dehumidifier work in controlling moisture?
In layman’s terms, desiccant dehumidifiers adsorb water molecules out of the air into a desiccant wheel. A second warmed air stream removes the water from the desiccant wheel and sends it outside of the structure in vapor structure.
Practically speaking, this cycle can develop the air quality inside a refrigeration or cold chain unit and forestall the harmful impacts of high relative humidity.
A dehumidifier can be added to a current cold chain unit related to the unit’s refrigeration system. The desiccant dehumidifiers are great speculation on the chance that you need total environment control in your cold chain application.
When the refrigerated display case or commercial refrigeration unit operates in the environment of a store, it exchanges and transfers heat and moisture with the air in the store environment. A technique has been fostered that assesses the impacts of relative moistness on the energy performance of refrigerated display cases.
