Cold storage refrigeration is a kind of facilities that use refrigeration system to control and maintain at a stable temperature in the cold storage room. These systems are widely used to preserve food, frozen products, pharmaceuticals, and other temperature-sensitive goods by preventing spoilage and maintaining product quality. It consists of condensing unit, evaporator unit, expansion valve, cold room temperature controller, cold room panels and so on. The cold storage refrigeration system is the heart of the cold storage refrigeration.
The cold storage design is according to the cold storage temperature, cold room size, application, and ambient conditions and so on. Based on these conditions, Glen Refrigeration will provide a cold storage refrigeration solution with high reliability and energy efficiency for commercial and industrial cold rooms.
The main components of a cold storage refrigeration include condensing unit, evaporator unit, expansion valve, cold room temperature controller and cold room panels and so on. The cold storage condensing unit and evaporator produce cold air to cold storage room. The cold room controller is the brain of the cold storage, it controls the refrigeration system ON and OFF according to target temperature. Cold room panel has a certain insulation performance, its function is to keep the cold air produced by the refrigeration system from leaking out of the cold storage room and maintain the stability of inner temperature.
The condensing unit is one of the main cold storage refrigeration equipment in the cold storage systems refrigeration. It is including cold storage compressor, condenser, fan motor, receiver, sight-glass, solenoid valve, high and low pressure switch, high and low pressure gauge, accumulator, stop valve and so on. Some of condensing units also have oil separator. Among these parts, compressor is the heart of the cold storage condensing unit. A good-quality refrigeration compressor is the key of the cold storage condensing unit. That’s why Glen Refrigeration always continue to use Sanyo, Panasonic and Copeland compressor. They are all famous brands and of high quality.
Glen Refrigeration provides different series of condensing units for commercial & industrial cold rooms, including:
The type of cold storage condensing unit is determined depend on the cold storage design and construction.
Whether water-cooled condensing unit or air cooled condensing unit, medium temp condensing unit or low temp condensing unit, they are all required to provide high reliability and high efficiency for cold storage industries.
Air cooler evaporator is indoor unit of the cold storage refrigeration equipment. In cold storage refrigeration cycle, the refrigerant in the air cooler evaporator absorbs heat from the cold storage room and evaporates to achieve the cooling effect. The selection of the evaporator and cold storage condensing unit plays an important role in cold storage refrigeration system design. In refrigeration systems, the size of the evaporator directly affects system performance, energy efficiency, and stability. Glen Refrigeration offers wide selection of the air cooler evaporator, including:
Although Glen Refrigeration is not the largest evaporator manufacturer in China, we are the company that best understands the importance of matching condensing units and cold room evaporators.
The expansion valve is used to regulate the refrigerant into the evaporator, ensuring accurate superheat control and efficient heat exchange. In cold storage refrigeration systems, the selection and matching of the condensing unit, evaporator unit and expansion valve is very important. Its selection directly affects the system’s refrigeration efficiency, operational stability, and equipment lifespan. Improper selection can lead to insufficient cooling, increased energy consumption, or even compressor damage.
Both excessively high or low refrigerant flow rates will affect the system’s efficiency during continuous operation. So proper expansion valve operation ensures stable superheat control, efficient heat exchange, and consistent temperature performance inside the cold room.
At same time, a good quality thermostatic expansion valve also plays a important role in cold storage refrigeration systems. Glen Refrigeration always insists to use Danfoss expansion valve, including the Danfoss r404a expansion valve and R449A expansion valve.
The last but most important, the correct installation of the refrigeration expansion valve temperature sensing bulb is a key factor in ensuring the efficient and stable operation of the refrigeration system.
The cold room controllers are used to manage cold storage room temperature regulation, defrost cycles, alarms and safety functions. It serves as the brain of the cold storage refrigeration. In cold storage applications, reliable controllers help optimize energy usage, maintain precise temperature settings, and respond quickly to abnormal operating conditions.
The selection of the cold room controllers should be according to the temperature requirements, condensing unit and evaporator and electric heater’s power and so on. For large cold storage facilities or cold storage requiring high temperature control accuracy (such as pharmaceutical cold storage), a control box with more complex control logic and higher precision should be selected.
The cold storage refrigeration system provides a stable, efficient, and reliable refrigeration performance; while the cold room panels and cold room doors are used to maintain the low temperature environment inside the cold storage room. The cold room panels and doors affect the refrigeration efficiency of cold storage, energy consumption, and the service life of cold storage. So the quality of cold room panels and cold room doors are as same important as the cold storage refrigeration units. Now most of the cold room panels and cold room doors used in the cold storage are polyurethane panel. They use lightweight polyurethane as the inner material. The surface material is made of color steel, stainless steel or embossed aluminum. According to different temperature and different requirements, the cold room panels can be divided according to the thickness, like 50mm, 75mm, 100mm, 120mm, 150mm, 200mm. It also can be divided according to surface materials, color steel, stainless steel, and embossed aluminum and the thickness of the surface materials.
Cold Room Panel According to Different Thickness
Cold Room Panel According to Different Surface Material
There are different kinds of cold room doors, including fully buried swing door, semi buried swing door, manual sliding door, electric sliding door, and so on. The most commonly used cold storage doors are semi buried swing door and sliding door. The swing door includes single open door and double open door. The thickness and the surface material of the cold room door can be customized according to customer’s need.
According to the cold storage dimension, it can be divided into small cold storage and large cold storage. The small cold rooms are essential for preserving food and perishable products, like Seafood Cold Storage, Flower Cold Storage, Meat Cold Storage, Vegetable Cold Storage, Milk Cold Storage, Fruit Cold Storage, Ice cream cold storage and so on. They are widely used in restaurants, hospitals, hotels, bakeries, butcheries and flower shops.
