Cold Storage Refrigeration

Cold storage is a kind of facilities that use refrigeration system to control and maintain at a stable temperature. It consists of refrigeration system, evaporator unit, cold room control panel, cold room panels. The refrigeration system is the heart of the cold storage refrigeration, including the condensing unit and evaporator unit. It produced cold air to cold storage. The cold room control panel is the brain of the cold storage, it controls the refrigeration system ON and OFF. Cold room panel has a certain insulation performance, its function is to keep the cold produced by the refrigeration system from leaking out of the cold storage room and maintain the stability of inner temperature.

Cold Storage Refrigeration Applications:

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.

Inverter Technology-What is Inverter Condensing Unit?

Inverter condensing unit is a condensing unit featuring inverter technology that help customers save energy use and costs. The inverter technology improves energy efficiency by efficiently controlling the commercial refrigeration compressor motor speed.

Normal condensing unit with fixed speed compressor maintain the set temperature by turning the compressor ON and OFF; when the cabinet temperature rises above the set temperature, the compressor turns on. While the cabinet temperature reaches the set temperature, the compressor turns OFF. The compressor is always ON and OFF frequently, which consumes more energy.

In inverter condensing unit, the cabinet temperature is adjusted by changing the compressor speed without turning the compressor ON and OFF frequently.

Compared to fixed speed condensing unit, variable speed condensing unit has less power loss and can save in energy.

Air Cooler Evaporator

Indoor Unit of Cold Storage Refrigeration

Air cooler evaporator is indoor unit of the cold storage refrigeration equipment. The selection of the evaporator and cold storage condensing unit plays an important role in cold storage refrigeration system design. 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 evaporator will not only affect the performance of outdoor condensing unit, but also the quality of the  cold storage refrigeration systems. Glen Refrigeration offers wide selection of the air cooler evaporator, including the slim type ceiling air cooler, dual discharge evaporator and box evaporator. Although we are not the largest evaporator manufacturer in China, we are the company that best understands the importance of matching condensing units and cold room evaporators.

Slim Type Air Cooler Evaporator

Glen Refrigeration offers low profile slim type air cooler evaporator for cold storage systems refrigeration. It is ideal for small cold storage room like catering, retail, and gas stations. It delivers reliable cooling at temperatures above and below zero degrees. The air cooler operates quietly and offers a cost-effective cooling solution, perfect for businesses looking to maintain a comfortable environment while saving space and money.

Double Flow Air Cooler Evaporator

The dual discharge evaporator is designed with ultra-thin structure, with air outlet on both sides. It is mainly used in processing rooms. It provides a more even distribution of the cooling air, which cools the room efficiently and evenly. The flat ceiling design allows for optimal utilization of space. Glen refrigeration offers good quality air evaporator. It makes us stand out of these evaporator manufacturers. Because the air cooler not only affect the cooling performance of the cold storage systems refrigeration, but also affect the reliability of cold storage condensing unit.

Box Evaporator

The box type evaporator is most common in cold storage refrigeration. It widely used in cold room and freezer room. According to the different cold storage temperature, the box evaporator can be divided into DD series and DJ series. DD series unit coolers with evaporator fin spacing 6.5mm~7mm designed for 2~8 ℃ cold storage room and -18°C freezer cold room. It delivers reliable cooling at temperatures above and below zero degrees. DJ series low temperature evaporator with evaporator fins spacing 9mm designed for -25 ℃ quick frozen room.

Cold Storage Refrigeration Units

Brings the advantages of easy installation and service

The outdoor condensing units and unit coolers are split system refrigeration cycle, while there is another kind of cold storage refrigeration cycle, that is monoblock refrigeration unit. It integrates condensing unit and air cooling evaporator into one package refrigeration system, brings the advantages of easy installation and service to the end users. The refrigerant of the cold storage refrigeration units has been pre-charged. Customers no need to charge the refrigerant anymore. It becomes more and more popular in cold storage market. Glen Refrigeration offers three differents monoblock refrigeration units, including wall mounted refrigeration unit, ceiling mounted monoblock refrigeration unit and monoblock R290.

Wall Mounted Refrigeration Unit for Cold Storage Refrigeration

This is Wall mounted refrigeration unit, also called Monoblock Refrigeration Unit, it integrated the condensing unit and evaporate unit together, featuring Sanyo inverter refrigeration compressor, EBM and WEIGUANG motor. The inverter wall mounted refrigeration unit has already charged in the refrigerant, makes customer easy to install and easy to maintenance. The cooling capacity is available in 1 HP, 2 HP, 3 HP and 4 HP. The power supply is available in 220V~240V/50HZ and 220V/60HZ.

Synergy operation of the R290 inverter refrigeration compressor and the intelligent controller provides higher efficiency. The evaporator is a dual discharge evaporator, in low height, ensures the largest effective volume of the cold storage room. Dual discharge evaporator with air outlet on both sides, provides a more even distribution of the cooling air.

Cold Room Panels and Doors

Maintain the low temperature environment inside the cold storage room

The cold storage refrigeration system  provides a stable, efficient, and reliable refrigeration performance; the cold room panels and cold room doors are used to maintain the low temperature environment inside the cold storage room. 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 and embossed aluminum. According to different temperature, 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 different surface materials, color steel, stainless steel, and embossed aluminum and the thickness of the surface materials.
