Cryogenic Cooler for Sale

Cryogenic cooler is a kind of refrigeration equipment, which is mainly used in industrial, commercial and living fields to provide low-temperature cooling water for various purposes. This type of equipment has a wide range of applications in chemical, pharmaceutical, food processing, biotechnology, electronics manufacturing and other industries. The working principle, components and precautions of the cryogenic cooler will be introduced in detail below.

1. Working principle

The working principle of cryogenic cooler is based on the cycle of refrigerant. The refrigerant circulates in the system and completes the four processes of compression, condensation, expansion and evaporation through the compressor, condenser, expansion valve and evaporator. During the whole process, the refrigerant continuously absorbs and releases heat to realize the preparation and supply of cold water.

The refrigerant is compressed in the compressor, increasing the temperature and pressure.

The high-temperature and high-pressure refrigerant enters the condenser and exchanges heat with the cooling water. The heat is taken away by the cooling water, and the refrigerant condenses into a liquid.

The liquid refrigerant passes through the expansion valve, and the pressure is reduced to form a low-temperature and low-pressure liquid-gas mixture.

The low-temperature and low-pressure refrigerant enters the evaporator, absorbs the heat of the cooling water, and evaporates it into gas. The cooling water releases heat during this process and lowers the temperature.

The refrigerant gas returns to the compressor again, and the cycle repeats.

2. Components

Die cryogenic cooler mainly consists of the following components:

Compressor: Responsible for compressing the refrigerant, increasing its temperature and pressure.

Condenser: used for heat exchange between refrigerant and cooling water to condense refrigerant into liquid.

Expansion valve: responsible for reducing the pressure of the refrigerant to form a low-temperature and low-pressure liquid-gas mixture.

Evaporator: used for refrigerant to absorb the heat of cooling water to realize the preparation of cold water.

Control system: including temperature sensors, pressure sensors, liquid level gauges, etc., responsible for monitoring and adjusting the operating status of the entire system.

3. Precautions for use

When using a cryogenic cooler, you need to pay attention to the following points:

Choose the right equipment: Choose the right low-temperature chiller model according to actual needs, including cooling capacity, operating temperature range, etc. At the same time, ensure that the equipment operates in an appropriate environment to avoid excessively high or low ambient temperature from affecting equipment performance.

During installation, ensure that the device is placed horizontally to avoid vibration. At the same time, make sure that there is enough space around the equipment for easy maintenance and inspection. When connecting the pipeline, pay attention to sealing to prevent water and air leakage.

System water quality requirements: The water used in the cooling water circulation system of the cryogenic cooler should meet the water quality requirements to prevent problems such as scaling, corrosion and microbial growth. Demineralized or treated water is recommended.

Regular inspection and maintenance: Regular inspection and maintenance of the cryogenic cooler, including cleaning the heat dissipation surfaces of the condenser and evaporator, to ensure good heat dissipation. Check the refrigerant pressure, system pressure, water pump running status, etc. to ensure the normal operation of the system.

Reasonably set the temperature and flow: adjust the outlet temperature and flow of cold water according to actual needs to improve the energy efficiency ratio. Avoid freezing the system due to too low outlet water temperature, affecting the normal operation of the equipment.

Safe operation: When operating the cryogenic cooler, the requirements of the equipment instruction manual should be followed to avoid accidents caused by misoperation. Make sure electrical connections and grounding are safe to prevent electric shock and equipment damage.

Deal with failures in a timely manner: If the cryogenic cooler fails, it should be stopped immediately for inspection to find out the cause of the failure and deal with it in time. Avoid running in an abnormal state for a long time, so as not to cause equipment damage or affect the production process.

Before the cryogenic cooler is restarted after a long shutdown, it should be inspected to confirm that all parts of the system are running well without leakage or blockage, so as to ensure the safe operation of the equipment.

In short, when using a cryogenic cooler, attention should be paid to reasonable selection, installation, operation and maintenance to ensure efficient and stable operation of the equipment and meet the demand for cold water supply.
