Product Q&A

Q:How to install the air-cooled chiller?

Choose a flat, open space with a firm cement foundation. Ensure free space for maintenance and ground weight capacity. Connect water pipes with matching diameters, ensuring stable water flow. Install pipes independently with vibration isolators. Treat poor water quality to avoid deposits affecting heat exchange.

Q:What is the difference between R22 and R410a refrigerant?

R410a is eco-friendly with zero ozone depletion, while R22 damages the ozone layer. R410a requires POE oil, has higher operating pressure (50-70% higher), and uses specialized high-strength copper pipes. It offers 47% higher cooling efficiency than R22 but cannot be directly replaced in existing R22 systems.

Q:What are the main functions of water-cooled screw chillers?

Main functions include refrigeration, heating, heat recovery, and cold recovery. They accurately control temperature for industrial processes (food, chemical, pharmaceutical) and provide stable heating for commercial spaces (malls, hotels), reducing energy costs through energy reuse.

Q:What is the working principle of the screw chiller unit?

The compressor sucks low-pressure refrigerant, compresses it into high-temperature gas, and sends it to the condenser to release heat. The liquid refrigerant is throttled by an expansion valve into the evaporator, where it absorbs heat from chilled water, cooling it. The chilled water is then circulated to cool indoor spaces.

Q:What is the warranty period for the chiller?

The free warranty period for the whole machine is 1 year from the date of delivery. Lifetime maintenance is provided, with paid services and preferential spare parts available after the warranty period.
