How Walk In Cooler Keeps Food Fresh
It is very hard to imagine life without the convenience of walking into a store and picking your favourite frozen snack from a walk in cooler
. But if you have ever stopped to look at a walk in coolerand wondered how it manages to keep food fresh, you are not alone. It is a common belief that refrigerators and walk in coolerswork on the same principle though nothing could be farther from truth. The technology operating in walk-in cooler is closer to air conditioners than refrigerators. Walk-in cooler use self generated cold air to maintain the temperature set at the thermostat. Their condenser and fans switch on and off automatically to sustain the desired temperature. This amazing technology is used by Bush Refrigeration for manufacturing walk in cooler which keeps the food fresh at the same time keeping it within the easy reach of the shoppers.The heart of any walk in cooleris its condenser. It jumps to life as soon as the temperature of the unit starts to rise above the temperature the thermostat is set at. The fans within the walk-in coolersuck the air inside, which then cools over the coils of condenser. The heat is absorbed by the coolant inside the coils and cooled down air is then moved out of the unit. The coolant within the coils is kept moving by regular pumping to avoid heating too much. This process continues till the temperature of air matches or becomes lower than the temperature fixed on the thermostat. Once that is achieved, walk in cooler automatically switches off.
The inbuilt mechanism ensures that condenser of walk in cooler does not overwork to the extent of getting covered with frost. When the temperature starts falling below the temperature set at the thermostat, the fans whir up to life. Only this time there is no coolant circulating in the coils. The hot air sucked in by the fans warms the coils gradually taking the temperature up. Once the temperature inside the walk in coolersreaches the fixed temperature, the defrost cycle comes to an end.
To make a walk-in coolereffective, proper insulation is of prime importance. Two to four inches of Styrofoam insulation around the walls and a rubber sealing gasket around the door are enough to make a standard walk in cooler airtight. When the air from outside does not enter the unit, the atmosphere inside the walk in coolerremains impervious to the outside temperature. Condenser does not have to work overtime as it only cools the air on the inside.
Its important to select a walk in coolerof a reputed brand such as Bush Refrigeration for your store to ensure a long and hassle free working. With a wide variety of models available online, its better to see the pictures and analyse the specifications of various models before you select one that meets your exact requirements.
