The air cooled screw cold (hot) water chiller is an integrated heating cooling double purposed central air conditioner that takes air as cold (hot) medium.

        It can heat effectively under minus 10, and found an increasingly wide application in regions where yearly conditioned air is available, but small load in winter and lack of water. Especially suitable in the region where the air temp is relative low and no boiler or other heater.

       The ultra-low temp air cooled cold/hot water chiller was co-developed by tsinghua University and our company, and can run at -20 working condition. The COP value is 2.15 when the ambient temp is -15. It has a higher energy efficiency ratio when running at low temp working condition.
