Abstract

The invention discloses a heat recovery system. The heat recovery system comprises a compressor, a first liquid storage tank, a second liquid storage tank, a first four-way valve, a second four-way valve, an outdoor heat exchanger, a hot water heat exchanger and an indoor heat exchanger, wherein the first four-way valve is connected with the second four-way valve, the inlet end of the outdoor heat exchanger is connected with a first valve port of the second four-way valve, the outlet end of the outdoor heat exchanger is connected with the first and second liquid storage tanks, the outlet end of the hot water heat exchanger is connected with a first valve port of the first four-way valve, the outlet end of the hot water heat exchanger is connected with the first liquid storage tank, the inlet end of the indoor heat exchanger is connected with a third valve port of the second four-way valve, the outlet end of the indoor heat exchanger is connected with the second liquid storage tank, a first electromagnetic valve is mounted between the inlet end of a compressor and a second valve port of the first four-way valve, and a second electromagnetic valve is mounted between the inlet end of the compressor and a second valve port of the second four-way valve. The heat recovery system solves the anti-freezing problem for an idle heat exchanger.

Description

technical field [0001] The invention relates to the field of heat recovery, in particular to a heat recovery system. Background technique [0002] The heat recovery system design in the prior art has the following problems: [0003] Putting the idle heat exchanger on the high-pressure side can solve the anti-freezing problem of the heat exchanger, but the hot water mode cannot defrost directly, so it needs to be solved by switching the mode; put the idle heat exchanger on the low-pressure side, the hot water mode can not be switched Mode defrost directly, but the antifreeze of the heat exchanger cannot be guaranteed. [0004] In the solutions in the prior art, either heating water cannot defrost and can only be converted to heating defrosting, or heating water defrosting cannot be implemented and can only be realized by switching to heating mode. [0005] In other solutions, when heating or hot water, the idle heat exchanger will be on the low pressure side, and the refrig...
