Cold components include several sections and systems that all work together to control the internal temperature and keep the products in favorable conditions. Here are some of the main components of the cold stores:
1. Compressor:
The heart compressor is the refrigeration system. Its task is to compress refrigerant, which increases its pressure and temperature. It should be noted that the chiller machine used in most modern refrigerators is a compressor compressor with compressor refrigeration cycle. The compressors used in these chillers are usually:
Reciprocating Compressors
Scroll Compressors
Centrifugal compressors br>
2. Condenser (Condense):
Air-Cooled Condenser: Cooling is done by air flow.
Water-Cooled Condenser: Cooling is performed by water .
Evaporator Condense: A combination of air and water is used for cooling.
1. Evaporator:
evaporator is a type of heat exchanger that evaporates inside, absorbing the heat of the refrigerator and reducing the temperature inside the refrigerator. Evaprators are made in financial and multiple pipes to optimize heat transfer.
1. Expansion valve (Expansion Valve):
Expansion valve or expansion of Volvo takes the refrigerant in the liquid state of the condenser and reduces the pressure to enter the evaporator, thereby evaporate the refrigerant and convert it to the gas. This valve actually plays the role of controlling the input flow to the evaporator.
1. Insulation: Insulation:
One of the most important components of any refrigerator is its insulation. Proper insulators minimize heat transfer from the outer environment into the refrigerator. Conventional insulators used include:
Polyurethane: with very high insulating properties.
Polystyrene: often used for walls.
1. Refrigerator door (Cold Room Doors):
The refrigerator door should be well insulated and easily opened and closed. Refrigerator doors usually have the following features:
strong insulation to prevent thermal exchange
Secure Locking and Handle System
Handheld or Auto Doors (Automatic)

1. Ventilation and Dehumidification System:
These systems are used to control moisture in the refrigerator and prevent the formation of ice and fog inside. Includes fresh air ventilation system and removes humid or contaminated air.
1. Control System (Control System):
Control systems play a role in managing and monitoring temperature, humidity and performance of refrigeration systems. More advanced systems have digital displays and network connectivity for remote monitoring and control.
1. Electrical Panel and Safety Systems:
All refrigeration systems, compressors and electrical equipment are controlled through the power panel. Safety systems are used to prevent compressor failure, increased pressure and prevent fire.
1. Internal Fans (Internal Fans):
Fans installed inside the refrigerator help distribute cold air uniformly in the interior. These fans are mounted on the back of the evaporator to flow the cool air throughout the refrigerator.
11. Lighting System (Lighting System):
For the interior lighting of the refrigerator, LED lamps or moisture and anti -shock lamps are used to provide adequate lighting without increasing temperature.
12. Alarm System (Alarm Systems):
Alert systems are essential for information in the event of problems such as unexpected temperature rise, compressor failure, or power outage. These systems can be alerted in voice or via message.
