Heat pump system with fuel gas as heat source

Abstract

The invention relates to the technical field of heat pumps, in particular to a heat pump system with a fuel gas as a heat source. The heat pump system comprises a refrigerant loop and a fuel gas combustion chamber, wherein the refrigerant loop is communicated via a compressor, an indoor heat exchanger, a throttling device and an outdoor heat exchanger in sequence; the outdoor heat exchanger is arranged inside the fuel gas combustion chamber and is used for exchanging heat with a high-temperature gas generated after the fuel gas is combusted inside the fuel gas combustion chamber. According to the heat pump system, the fuel gas is adopted as the heat source, the heat of the combusting fuel gas can be exchanged with that of the outdoor heat exchanger; meanwhile, the outdoor heat exchanger is arranged in a relatively sealed high-temperature gas environment, and sufficient heat exchange can be achieved, so that nearly all heat of the combusting fuel gas can be transferred into a room, and thus indoor heating can be achieved; the heat pump system is high in fuel gas utilization rate and good in heating effect; the outdoor heat exchanger is arranged inside the fuel gas combustion chamber and is not frosted, so that the heat exchange effect can be ensured, and the heat pump system is not constrained by a low-temperature environment.

Description

technical field [0001] The invention relates to the technical field of heat pumps, in particular to a heat pump system using gas as a heat source. Background technique [0002] When heating in winter in cold and low temperature areas in the north, the following methods are generally adopted: coal-fired heating, electric heating for heating, wall-hung boiler heating, air source heat pump heating or water source, ground source heat pump heating, but the above methods have defects: coal-fired heating, Serious pollution; heating with electric heating, high power cost, poor heating effect, and poor economy; heating with wall-hung boilers, low heat transfer efficiency, and poor heating effect; heating with air source heat pumps, poor heating effect Frosting; water source, ground source heat pump heating, complex installation, high cost, and more limited installation locations. Contents of the invention [0003] Based on this, in order to solve the problems of low heat exchange ...
