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 kept at the right temperature (generally low) and humidity level depending on the particular item. These characteristics are pre-configured based 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 used in a cold-storage facility to assist keep the environment and temperature appropriate for each item being stored. The cold room manufacturer will be the best choice to build cold storage for your items. The essential elements of a cold storage room are as follows:
It is the primary element that powers the frigid chamber. The only thing that requires energy to operate is it. In a chilly environment, the compressor uses practically all of the power. It is employed 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.
It is necessary to take the heat away 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 determined by the condenser’s heat exchange efficiency, which serves as a heat sink.
Here is where the high-pressure liquid condensate is kept. 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.
The expansion valve:
Using a throttling device, it lowers the refrigerant’s temperature and pressure. 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.
Here is where the cyclical process that lowers the storage items’ temperature takes place. It absorbs heat from the ambient or storage space that is meant to be cooled. The liquid refrigerant is vaporized using this heat. The food items are cooled and preserved with the aid of CBFI cold room manufacturer.
Through the action of convection, the cooled air is dispersed throughout the space, bringing the temperature of the space to the desired level. In essence, the compressor raises the temperature and pressure of 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 moved to the reservoir where it will be stored. To further lower the temperature and pressure in the liquid form, the refrigerant is transferred to an expansion valve. In the final phase, the refrigerant is converted back into a gaseous state in the evaporator, where the heat from the environment is utilized to provide the cooling effect. The blower circulates this chilly air.
