the domestic water flows through the domestic hot water circulating pump (3.1) and the fourth electric two-way valve (3.2) through pipelines, sequentially enters the second heat exchanger (3.3) and the secondary side of the third heat exchanger (3.4) for heat exchange, and then flows out; the waste heat hot water flows through the third electric regulating valve (3.5) through a pipeline and flows out after heat exchange at the primary side of the third heat exchanger (3.4).
6. The triple co-generation device for heating, air conditioning and domestic hot water of claim 5, wherein:
the device also comprises a fourth electric regulating valve (4) and a fifth electric regulating valve (5);
4 paths of the waste heat hot water, wherein 1 path of the waste heat hot water enters the primary side of the second heat exchanger (3.3) of the hot water heating module, wherein 1 path of the waste heat hot water enters the primary side of the third heat exchanger (3.4) of the hot water heating module, wherein 1 path of the waste heat hot water enters the primary side of the first heat exchanger (1.3) of the heat supply module, and wherein 1 path of the waste heat hot water enters a hot water inlet of the low-temperature hot water type lithium bromide refrigerator (2.3) of the refrigeration module;
the primary side water outlet of the first heat exchanger (1.3) of the heat supply module or the waste heat hot water outlet of the refrigeration module is divided into two paths, wherein one path flows through the fourth electric regulating valve (4) and then is connected to the waste heat hot water return port; one path of the waste heat water flows through the fifth electric regulating valve (5) and enters the hot water heating module, and then the waste heat water receiving and returning port is connected to the second heat exchanger (3.3) of the hot water heating module after heat exchange.
7. The triple co-generation device for heating, air conditioning and domestic hot water of claim 2, wherein: the modules of the device are integrated into a single module.
