MULTI-SPLIT COLD AND HOT WATER UNIT

WIPO Patent Application WO/2020/015296

A1

The present invention relates to the field of refrigeration devices, and provides a multi-split cold and hot water unit. The multi-split cold and hot water unit comprises: an outdoor heat exchanger unit (1), an indoor heat exchanger unit (2), a heating heat exchanger unit (3), and a regulating valve (4); the regulating valve (4) comprises ports which are respectively communicated with refrigerant inlet/outlet pipelines of the outdoor heat exchanger unit (1), the indoor heat exchanger unit (2), and the heating heat exchanger unit (3), and a regulating member for switching the communication relationship of refrigerant flow paths between the plurality of ports. The multi-split cold and hot water unit can realize flexible matching of various water path conveying modes such as refrigeration, heating, and floor heating, thereby greatly simplifying the water path mounting complexity of the multi-split cold and hot water unit; the multi-split cold and hot water unit has the advantages of reducing mounting costs, improving pipeline mounting convenience, greatly reducing water path running resistance, and improving user experience.
