Abstract

The invention discloses a fuel gas-assisting type heat pump system and a control method thereof. The fuel gas-assisting type heat pump system comprises a water tank, a heat pump main machine, a heat exchange coil, a fuel gas main machine, a heating device, a first switching device, a second switching device, a first temperature detection device, a second temperature detection device, a third temperature detection device and a controller, wherein the heat pump main machine is connected with the water tank so as to heat water in the water tank, the heating device is connected with the heat exchange coil and the fuel gas main machine, the first switching device and the second switching device work cooperatively to form a first circulation loop, a second circulation loop and a third circulation loop, and the controller controls one of the first circulation loop, the second circulation loop and the third circulation loop to be connected according to the temperature detected by the first temperature detection device, the temperature detected by the second temperature detection device and the temperature detected by the third temperature detection device, and controls the operating state of the heat pump main machine and the operating state of the fuel gas main machine. The fuel gas-assisting type heat pump system is high in energy efficiency, and the fuel gas main machine has the hot water supply effect and further has the heating effect.

Description

technical field [0001] The invention relates to the field of heat pump equipment, in particular to a gas-assisted heat pump system and a control method thereof. Background technique [0002] A heat pump system heats hot water or provides heating by absorbing heat from the air using the reverse Carnot cycle principle. With the decrease of the external ambient temperature in winter, the heat absorbed by the heat pump from the atmosphere decreases, and the heating effect of the heat pump becomes poor. [0003] In order to improve the heating capacity of the heat pump system under low temperature conditions, industry insiders have proposed the use of gas-fired devices to supplement the attenuation of the heat pump at low temperatures. The existing gas-assisted heat pump systems all use the gas-fired device to supplement the heating of domestic hot water, which cannot solve the heating problem. [0004] In addition, using a heat pump for heating in winter is difficult to achiev...
