Air Cooled Chiller Principle of Operation

The air-cooled chiller achieves cooling through a refrigeration cycle system, and its core working principle is as follows:

• Refrigerant cycle

• Evaporative heat absorption: Liquid refrigerant absorbs the heat of chilled water in the evaporator, evaporates into low-temperature and low-pressure gas, and cools the chilled water (usually outputting 7-12 ℃ cold water).

• Compression heating: The compressor compresses low-temperature gaseous refrigerant into high-temperature and high-pressure gas, which is then transported to the condenser.

• Condensation heat dissipation: High temperature refrigerant is forced to ventilate and dissipate heat through a fan in the condenser, condensing into high-pressure liquid.

• Throttling and pressure reduction: The expansion valve throttles and reduces the pressure of the high-pressure liquid refrigerant, which then re enters the evaporator to complete the cycle.

• Air cooling system

By using an axial flow fan to draw ambient air into the condenser, the refrigerant heat is directly carried away without the need for a cooling tower or external water source, and the heat dissipation efficiency is affected by the ambient temperature.

Air Cooled Chiller FAQ

1. Q: What is the difference between air-cooled chillers and water-cooled chillers?

A: Air coolers dissipate heat through fans without the need for cooling towers, making installation simple but slightly inefficient; Water coolers require a cooling water system, which is more efficient but complex to maintain, making them suitable for large-scale projects.

2. Q: What scenarios are air-cooled chillers suitable for?

A: Suitable for small and medium-sized refrigeration needs such as shopping malls, small factories, data centers, and communication base stations, especially suitable for environments with water scarcity or limited space.

3. Q: Does the air-cooled machine need an additional cooling tower?

A: No need, the air cooler directly dissipates heat through ambient air, eliminating the need for cooling towers and water pump systems.

4. Q: Will high temperature weather affect the effectiveness of wind turbines?

A: Yes, the heat dissipation efficiency decreases when the ambient temperature exceeds 35 ℃. It is recommended to choose a high-temperature resistant model or increase ventilation measures.

5. Q: Is the air cooler noisy?

A: The operating noise mainly comes from the compressor and fan, usually ranging from 65-75 decibels. Low noise models can be selected or soundproof covers can be installed.

6. Q: How often does the air-cooled machine need maintenance?

A: It is recommended to clean the dust on the condenser fins every quarter and check the refrigerant and circuit every year to ensure heat dissipation efficiency.

7. Q: Do we need antifreeze in winter?

A: If operating in a low-temperature environment, it is necessary to add antifreeze or install heating belts to prevent frozen water from freezing and damaging pipelines.

8. Q: Does the air-cooled machine consume high power?

A: Slightly higher than water-cooled machines, but eliminates the energy consumption of cooling towers and water pumps, and the overall electricity cost needs to be evaluated comprehensively.

9. Q: How to choose a suitable air-cooled model?

A: Select based on cooling capacity (kW/RT), ambient temperature, and noise requirements, and reserve a margin of 10% -20% to cope with peak loads.
