Open type cold storage unit is a common refrigeration equipment, and its specific introduction is as follows:

Structural composition

It usually consists of a compressor, condenser, evaporator, expansion valve, electronic control system, and various refrigeration accessories. Compressors are generally selected from internationally renowned brands such as Bitzer, Gulun, Danfoss, etc., which have high reliability. Condensers are often made of copper tubes, aluminum sheets, or high-efficiency shell and tube types. The copper tubes are tightly expanded with the aluminum sheets, resulting in high heat transfer efficiency and long service life. The evaporator can evaporate and absorb heat from the refrigerant liquid, achieving a cooling effect. Expansion valves can throttle and depressurize refrigerants, controlling their flow rate. The electronic control system is responsible for controlling and monitoring the operation of the unit.

working principle

Similar to other cold storage units, the compressor sucks in low-temperature and low-pressure refrigerant vapor from the evaporator, compresses it into high-temperature and high-pressure superheated vapor, and then discharges it into the condenser. In the condenser, the refrigerant superheated vapor is cooled and condensed into liquid by dissipating heat to the surrounding air under the action of the fan. The liquid refrigerant enters the evaporator after being throttled and depressurized by the expansion valve. It absorbs heat and evaporates in the evaporator, becoming low-temperature and low-pressure refrigerant vapor, which is then sucked in by the compressor again. This cycle achieves refrigeration.

Performance characteristics

-High heat exchange efficiency:By using efficient condensers and evaporators, heat exchange can be quickly achieved, improving refrigeration efficiency, shortening the cooling time of food and other goods, and better maintaining their quality.

-Good operational reliability:High quality refrigeration components are selected, fully equipped, and the automatic control valves, electronic control systems, and other accessories are all from international and domestic first-line brands to ensure stable and reliable operation of the unit.

-Low noise:Some units use external rotor condensing fans, which have low noise during operation and will not cause significant interference to the surrounding environment. They are suitable for places with high noise requirements, such as supermarkets, hospitals, hotels, and nearby cold storage facilities.

-Wide applicability:The product series is complete and suitable for a wide temperature range, which can meet different refrigeration needs such as preservation, refrigeration, ice making, and frozen water. It is suitable for various working conditions such as high temperature, medium temperature, and low temperature, and can be widely used in various cold storage refrigeration equipment.

-Easy maintenance:The unit structure is relatively simple, and the open design makes each component easy to inspect, maintain, and replace. Meanwhile, the installation of waterproof terminal junction boxes facilitates user wiring, reducing maintenance difficulty and costs.

application area

-Food processing and storage:Used for preserving fruits and vegetables, freezing meat, storing seafood, refrigerating dairy products, etc., it can extend the shelf life of food, maintain its freshness and quality.

-Chemical and Pharmaceutical:In chemical production, providing a low-temperature environment for reaction vessels, storage tanks, etc. ensures the smooth progress of chemical reactions and stable storage of raw materials. In the pharmaceutical industry, processes such as refrigeration and freeze-drying are used to ensure the effectiveness and safety of drugs.

-Other fields:It can also be applied to places with strict temperature requirements such as grain storage, scientific research experiments, and electronic component production, providing a stable low-temperature environment for them.
