The Refrigeration Principle of the Air-Cooled Low-Temperature Chiller, Makes Cooling Simpler!

The air-cooled low-temperature chiller, as a highly favored refrigeration equipment, is widely used and well-received in many fields. So, how does the air-cooled low-temperature chiller work? Let's delve into the working principle of the air-cooled low-temperature 

The air-cooled low-temperature chiller utilizes a compression refrigeration method, which mainly involves refrigerant circulation, cooling principles, and model classification.

Refrigerant Circulation

The refrigerant circulation of the air-cooled low-temperature chiller mainly involves components such as the evaporator, compressor, condenser, and expansion valve. The refrigerant absorbs heat from the water in the evaporator and starts evaporating. The evaporated refrigerant gas is then drawn and compressed by the compressor. The high-temperature, high-pressure gas enters the condenser, where the refrigerant gas releases heat and condenses into a liquid. Finally, the refrigerant, now a low-temperature, low-pressure liquid, passes through the expansion valve and re-enters the evaporator, completing the refrigerant circulation process.

Cooling Principle

The air-cooled low-temperature chiller cools the water to the desired temperature through refrigerant circulation. The refrigerant absorbs the heat from the water and evaporates in the evaporator, which consumes a significant amount of heat and lowers the water temperature. At the same time, the refrigerant gas releases heat in the compressor and condenser, which needs to be dissipated into the environment to maintain the normal circulation of the refrigerant.

Model Classification

The air-cooled low-temperature chiller has various models according to different application needs, such as water-cooled, air-cooled, and parallel units. The water-cooled low-temperature chiller indirectly cools the chilled water using cooling water, while the air-cooled low-temperature chiller reduces the outlet water temperature by using outdoor air to cool the water in condenser coils. Parallel units combine multiple low-temperature chillers to meet higher refrigeration capacity requirements.

How to Maintain An Water Chiller in Winter?

Winter chiller operation requires antifreeze measures to ensure stability. Following these guidelines can help you prevent freezing and safeguard your 

When the Temperature Is Below 0℃, Add Antifreeze: Antifreeze can lower the freezing point of the circulating water, preventing freezing and cracking of pipes and ensuring the sealing of the pipes. Therefore, when the temperature is below 0℃, promptly add antifreeze.

Antifreeze Mixing Ratio: To ensure the normal operation of the laser chiller, strictly control the ratio of antifreeze to water. The recommended ratio is 3:7.

*Tip: It is advised not to exceed 30% for the added antifreeze ratio to prevent pipe blockage and accessories corrosion due to high concentration.

Water Chiller Running 24 Hours: Keep the laser chiller continuously running 24 hours when the ambient temperature is below -15℃ to ensure continuous water circulation and prevent freezing.

Regular Inspections: Periodically check the chiller's cooling system, including cooling water pipes and valves, for any leaks or blockages. Address issues promptly to ensure normal operation.

What Should You Keep In Mind When Not Using The Chiller In Winter?

1. Drainage: Before long-term shutdown, drain the chiller to prevent freezing. Open the bottom drainage valve to let out all the cooling water. Remove the water pipes and internally drain by opening the water fill port and the valve. Then use a compressed air gun to thoroughly dry the internal pipes. 

Note: Avoid blowing air at the joints where yellow labels are pasted above or on the side of the water inlet and outlet, as it may cause damage.

2. Storage: After draining and drying, reseal the chiller. It's recommended to temporarily store the equipment in a place that doesn't affect production. For water chillers exposed to the outdoors, consider measures such as wrapping the chiller with insulating materials to minimize temperature reduction and prevent dust and airborne moisture from entering the cooler.

During winter chiller maintenance, focus on antifreeze fluid, regular inspections, and proper storage. For further assistance, feel free to consult our customer service team via service@teyuchiller.com. For more about TEYU S&A water chiller maintenance, please click TEYU Chiller Case.
