How does an air-cooled chiller dissipate heat, and what distinguishes it from a water-cooled chiller?

The air-cooled chiller dissipates heat by means of fans blowing air across the condenser, without the need for external cooling water. The main distinction is that it does not require a cooling tower, making installation simpler and more suitable for environments where water resources are limited or water-cooled systems are impractical.

What does “split system” mean in a split-system air-cooled chiller, and when is this configuration appropriate?

Split system refers to the separation of the compressor and condenser into distinct units. This configuration is appropriate for locations with limited installation space, insufficient ventilation, or where it is desirable to reduce the noise level of the main unit in the workspace.

How does high ambient temperature affect the operation of an air-cooled chiller?

Excessive ambient temperature reduces cooling efficiency and may trigger compressor overload protection. It is recommended to install the unit in a well-ventilated area where the temperature does not exceed 40°C.

What specific considerations apply when air-cooled chillers are used in food or pharmaceutical applications?

The cooling medium and contact materials should comply with relevant standards (e.g., stainless steel, food-grade hoses, and seals). Leak prevention, cleanability, and indirect cooling via plate heat exchangers should be ensured to prevent direct contact between the cooling medium and the product. Compliance with applicable hygiene standards and validation procedures is also required.

What should be checked if cooling performance decreases in a high-temperature environment?

Two aspects should be examined:

  • Whether the condenser fins are contaminated with dust or oil; they should be cleaned with compressed air or suitable cleaning agents to maintain heat exchange efficiency.
  • Whether the cooling fan is malfunctioning (e.g., reduced speed or stopped operation); inspect the fan motor and wiring, and repair or replace components as necessary to maintain proper airflow.
What is the function of an air-cooled chiller in mold processing?

It maintains stable mold temperatures, improves product forming quality, and reduces the rate of defects and rework.

Why are air-cooled chillers used in coating production?

Stable temperature control prevents fluctuations in material properties, ensuring consistent color, viscosity, and coating performance.

Can cooling equipment meet the temperature control requirements for photovoltaic module testing?

Yes. The temperature control accuracy reaches ±0.1°C, with rapid heating and cooling response, making it suitable for component aging and performance testing.

What role does temperature control equipment play in pharmaceutical research and development?

It provides a stable thermal environment to ensure data accuracy, consistency, and repeatability in experimental processes.

What is the purpose of using a low-temperature chiller in pharmaceutical production?

Low-temperature chillers are used to ensure stable temperature control in reactors and fermentation tanks, thereby improving product quality and production safety.

Can a low-temperature industrial chiller be used for laboratory low-temperature testing?

Yes. It provides a stable low-temperature environment for materials, electronic components, or biological samples.

How is a low-temperature chiller used in the food industry?

In the food industry, low-temperature air-cooled chiller supports quick freezing, low-temperature storage, and rapid beverage cooling processes.

Is a cooling tower required for a water-cooled chiller?

Yes. The core cooling system relies on a chiller with cooling tower. The cooling tower removes heat from the condenser discharge water, lowering its temperature before it returns to the chiller for continued cooling support. Without a cooling tower, heat exchange cannot be completed, and the unit will not operate properly.

What should be done if the water temperature becomes too high during operation?

Inspect the following three points:

  • Check whether the cooling tower is dirty or blocked (e.g., scaling on the filler or fan failure); clean or repair as needed.
  • Verify whether the circulating water pump is short of water or has insufficient head; check the valve and pump performance.
  • Examine whether the condenser is scaled; periodic descaling with professional cleaning agents is required to restore heat exchange efficiency.
What causes water leakage issues?

Leakage typically results from aging or deterioration of pipes and components, such as failed sealants at pipe joints, damaged cooling tower filler, or corroded condenser copper tubes. Regular inspection of pipe connections, valves, and cooling tower water levels is essential. Any detected leaks should be addressed by replacing seals or worn parts promptly.

Is a water-cooled chiller suitable for all applications?

Not entirely. It depends on a stable water supply (tap water or circulating water) and sufficient space for cooling tower installation. It is not suitable for areas with limited water resources, small workshops, or temporary cooling setups such as outdoor construction sites.

It is best suited for large-scale facilities with fixed installations and high cooling loads such as industrial plants, data centers, and environments with reliable water supply.

How should an injection molding plant select an appropriate water-cooled chiller during hot seasons?

Determine the required cooling capacity based on the total cooling tonnage of the injection molding machines and the number of molds, and prioritize high-efficiency models to reduce power consumption.

How much does a water-cooled chiller affect mold cooling stability?

A water-cooled chiller provides constant low-temperature circulating water, which helps shorten cooling cycles and improve product consistency.

How can a beverage production line maintain low temperatures during continuous operation?

Choose a water-cooled chiller with two independent cooling systems, each operating at its own temperature, providing separate cooling for beverages and precise temperature control for equipment.

For pharmaceutical production requiring precise temperature control, how should an industrial chiller be selected?

Select a system with ±0.1 °C temperature accuracy and a PLC touchscreen controller to ensure process stability.

What are the water quality and pressure requirements for water-cooled chillers in chip manufacturing environments?

Recommended outlet pressure: 1–10 kg adjustable. The system should include pure water filtration and online pH monitoring to maintain water quality.

What special configurations are needed to cool cutting fluids in machine tools?

Select a chiller compatible with cutting fluid as a coolant and constructed from corrosion-resistant materials to ensure long-term durability.

Which chiller model is suitable for food processing equipment that operates continuously?

A water-cooled low-temperature chiller is recommended, as it can run continuously around the clock while maintaining stable cooling performance.

How can a plastic injection molding plant ensure simultaneous cooling for multiple machines in a high-temperature workshop?

A 9.9–240kW water-cooled chiller is ideal for this setup. It provides sufficient cooling capacity, high energy efficiency, and reliable operation under heavy production loads.

What solution is available for chemical workshops where reactors require cooling water below -15 °C?

A low-temperature water-cooled chiller is recommended, customizable for -35 °C operation and equipped with corrosion-resistant materials to ensure safe, long-term use.

What are the main advantages of a scroll chiller?

Its key strengths lie in energy efficiency (the scroll compressor operates without suction or discharge valves, offering 10–15% higher efficiency than other types), stability (fewer moving parts, minimal vibration, low failure rate), and quiet operation (a smooth compression process typically reduces noise by 5–10 dB compared to screw chillers).

How should I choose the right scroll chiller model?

First, calculate the actual cooling load (adding a 10–20% safety margin). Then select between air-cooled or water-cooled systems based on the site, and determine parameters according to outlet temperature, ambient conditions, power supply, and installation space.
