Air source heat pump

Air source heat pump (chiller) is a central air conditioning unit with air as cold and heat source and water as carrier refrigerant. Air source heat pump unit with 35kw, 65kW, 80kW, 130kW, 160kW as the benchmark module, realizes the arbitrary combination of 16 modules, forming a combination product in the range of 35kw-2560kw. It has the advantages of environmental protection, simple installation, flexible, moderate investment, short construction period, etc. now it is more and more widely used in animal husbandry and breeding industry.
