A cold storage facility is generally used to keep food products that, under typical circumstances, have a high likelihood of spoiling quickly. Fruits, vegetables, fish, and meat are just a few examples. These food items are keep at the ideal temperature (generally low) and humidity level need for each particular item. These characteristics are pre-configure base on what is being held in almost all cold storage rooms. Some chilly rooms have changeable versions of these characteristics.

Building and Operation of a Cold Storage Facility

A refrigeration system is use in a cold-storage facility to assist keep the environment and temperature appropriate for each item being stored. The essential elements of a cold storage room are as follows:

Compressor

The compressor is the main device that powers the cold room. The only thing that requires energy to operate is it. In a chilly environment, the compressor uses practically all of the power. It is employe to increase the pressure and temperature of the refrigerant vapour leaving the evaporator. The boiling point rises with pressure, allowing the compressor to condense the refrigerant (for instance, ammonia) at the condenser’s temperature.

Condenser

This device is necessary to extract heat from the circulating water and the refrigerant. At high temperatures and pressures, it converts the condenser’s phase from one of gas to one of liquid. The efficiency of the cold storage plant is determine by the condenser’s heat exchange efficiency, which serves as a heat sink.

Receiver

The high-pressure liquid condensate is keep in the receiver. The phase change from the condenser brings the refrigerant here. The liquid refrigerant travels to the expansion valve to lower the temperature and pressure after it has reached the receiver component.

Expansion Valve

This component uses a throttling mechanism to lower the temperature and pressure of the refrigerant. Friction and a change in the refrigerant’s temperature and pressure are what cause the throttling process. As it moves from the Receiver to the Evaporator, its pressure changes.

Evaporator

This is where the cyclical process that lowers the store objects’ temperature takes place. It absorbs heat from the ambient or storage space that is mean to cool. The liquid refrigerant is vaporise using this heat. The food cool items are preserve in this way.

Blowers

The cooled air is disperse throughout the space through convection, resulting in the desire room temperature.

In essence, the compressor raises the temperature and pressure the refrigerant to lower its boiling point. The condenser cools the refrigerant as it transitions from a gaseous to a liquid form. Now the refrigerant is move to the reservoir where it will store. To further lower the temperature and pressure in the liquid form. The refrigerant is transfer to an expansion valve. In the final phase, the refrigerant is convert back into a gaseous state in the evaporator. Where the heat from the environment is utilize to provide the cooling effect. This cool air is circulate by the blower.
