JLSFD-4HP Air-Cooled Low Temperature Chiller Ethylene Glycol Chiller, Chiller, Freezer

Production Description:

Glycol chillers are a common type of chiller that use ethylene glycol as the cooling medium. The following is a description of the glycol chiller:

1. Working principle: The ethylene glycol chiller adopts the principle of condensation cycle. Ethylene glycol acts as a cooling medium in the circulation system, and the ethylene glycol is sent to the cooling equipment through the circulation pump, and returns to the chiller for condensation after absorbing heat, and then circulates again.

2. Cooling medium: Ethylene glycol is a commonly used cooling medium with good thermal conductivity and antifreeze performance. It has a low freezing point and boiling point, which can provide stable cooling effect at low temperature.

3. Temperature control range: Glycol chillers are usually able to provide lower cooling temperatures, generally ranging from -5°C to -40°C, or even lower. This makes it useful in applications requiring cryogenic cooling.

4. Application fields: Ethylene glycol chillers are widely used in various scenarios that require low-temperature cooling or constant temperature control. It is commonly used in industries such as laboratories, scientific research, medical treatment, pharmaceuticals, chemicals, food processing and electronics.

5. Corrosion resistance: Ethylene glycol has good corrosion resistance and is compatible with various materials, such as stainless steel, copper, aluminum, etc. This gives the glycol chiller high durability when in contact with cooling equipment and piping.

6. Environmental friendliness: Ethylene glycol is considered to be a relatively environmentally friendly choice compared to some other cooling media. It is less volatile and less toxic, and has less impact on the environment.

It should be noted that the glycol chiller needs to follow relevant safety operating procedures during use and maintenance to ensure its safe and reliable operation. In addition, the selection of a glycol chiller should be determined based on the specific application needs to ensure that it can meet the required cooling temperature and performance requirements.

Production Features:

Glycol chillers have some advantages and disadvantages over other cooling media. The following is a comparison description:

Advantage:

1. Low temperature range: Glycol chillers can provide lower cooling temperatures, generally ranging from -20°C to -40°C, or even lower. This makes it useful in applications requiring cryogenic cooling.

2. Freeze resistance: Ethylene glycol has good antifreeze performance, and its freezing point is low, which can prevent the cooling system from freezing and damage in low temperature environment. This makes glycol chillers suitable for applications in cold climates or low temperature environments.

3. Thermal conductivity: Ethylene glycol has good thermal conductivity, can effectively absorb and transfer heat, and provide a stable cooling effect. This makes glycol chillers excellent in heat control and temperature stability.

4. Corrosion resistance: Ethylene glycol has good corrosion resistance to many materials and is compatible with common materials such as stainless steel, copper, and aluminum. This reduces corrosion problems in contact with cooling equipment and piping, increasing system durability.

Disadvantages:

1. Higher viscosity: Ethylene glycol has a higher viscosity, and its fluidity may be slightly worse than other cooling media. This may require more powerful pumps and piping to ensure good cooling flow.

2. Relatively low heat dissipation capacity: Compared with some other cooling media, ethylene glycol has slightly lower thermal conductivity. This may require a larger heat exchanger area or longer cooling time to achieve the same cooling effect.

3. Higher cost: Compared with some other cooling media, the cost of ethylene glycol is higher. This needs to consider economic factors when choosing, and weigh the relationship between its performance and cost.

Overall, glycol chillers offer significant advantages in cryogenic cooling applications, but selection requires a combination of application-specific needs, performance requirements, and economics.

Working Principle:

Specifically, the working principle of the air-cooled low-temperature chiller is:

1.The compressor sucks in low-temperature and low-pressure refrigerant and compresses it into a high-temperature and high-pressure gas.

2.The high-temperature and high-pressure gas enters the condenser, releases heat into the air through the radiator, and turns into a high-temperature and high-pressure liquid.

3.The high-temperature and high-pressure liquid enters the evaporator, exchanges heat with the outside through the evaporator, and turns into low-temperature and low-pressure steam.

4.The low-temperature and low-pressure steam enters the compressor again, and the cycle repeats.
