[0002] In the existing multi-connected system, generally the multi-connected outdoor unit + multi-connected indoor unit constitutes a multi-connected system. When the indoor unit is running in heating mode, it provides hot air to the room, and at the same time, the heat exchanger of the outdoor unit evaporates and absorbs heat from the air. , the finned heat exchanger of the outdoor unit is prone to frost at low temperature, which will reduce the heating capacity of the indoor mechanism and require regular defrosting. During the defrosting period of the finned heat exchanger of the outdoor unit, the indoor unit cannot be continuously provided Heating will lead to a drop in the indoor ambient temperature and a decrease in comfort

The invention discloses a multi-split system with a multi-heat-source switching function. The multi-split system comprises a multi-split indoor unit, an outdoor unit and a hydraulic module, wherein the multi-split indoor unit comprises a compressor, an outdoor heat exchanger, a first four-way valve, a second four-way valve and a third four-way valve, the hydraulic module comprises a hydraulic heatexchanger and a ground source side, the hydraulic heat exchanger is connected with the ground source side through a water inlet pipe and a water return pipe, and heat exchange is carried out betweenthe hydraulic heat exchanger and ground source water on the ground source side to provide a heat source for the multi-split indoor unit; and the system further comprises an environment temperature unit used for detecting the outdoor environment temperature in real time, so that in the low-temperature environment, the hydraulic module is correspondingly selected to be started to serve as the heat source or stopped serving as the heat source based on the detected outdoor environment temperature, and the power-on or power-off action of the first four-way valve, the second four-way valve and the third four-way valve is correspondingly controlled.
Description
technical field [0001] The invention relates to the technical field of multi-line systems, in particular to a multi-line system with multi-heat source switching. Background technique [0002] In the existing multi-connected system, generally the multi-connected outdoor unit + multi-connected indoor unit constitutes a multi-connected system. When the indoor unit is running in heating mode, it provides hot air to the room, and at the same time, the heat exchanger of the outdoor unit evaporates and absorbs heat from the air. , the finned heat exchanger of the outdoor unit is prone to frost at low temperature, which will reduce the heating capacity of the indoor mechanism and require regular defrosting. During the defrosting period of the finned heat exchanger of the outdoor unit, the indoor unit cannot be continuously provided Heating will lead to a drop in the indoor ambient temperature and a decrease in comfort.
