Abstract

The invention provides an engine-driven air source heat pump which is used for producing hot water or hot air. The engine-driven air source heat pump comprises an engine, a transmission device, a compressor, a first heat exchanger, a second heat exchanger and an economizer, the compressor is provided with an exhaust port, an air suction port and an air supply port, and the second heat exchanger is provided with a first circulation port and a second circulation port. The engine-driven air source heat pump is characterized by further comprising a smoke refrigerant heat exchanger, a cooling water refrigerant heat exchanger and a refrigerant three-way valve, wherein refrigerant in the smoke refrigerant heat exchanger absorbs heat and evaporates from smoke in a smoke exhaust pipeline of the engine, the smoke refrigerant heat exchanger is connected with refrigerant of the economizer in series or in parallel, the refrigerant absorbs heat and evaporates in the smoke refrigerant heat exchanger and the economizer and then returns to the compressor through the air supply port, refrigerant in the cooling water refrigerant heat exchanger absorbs heat and evaporates in cooling water and communicates with the air suction port, and the second circulation port is connected with the exhaust port and the air suction port through the first refrigerant three-way valve.

Description

technical field [0001] The invention belongs to the technical field of heat pumps, and in particular relates to an engine-driven air source heat pump. Background technique [0002] At present, boilers widely used consume a lot of primary energy, have high operating costs, and generate a large amount of carbon emissions. Engine-driven air source heat pumps have the characteristics of high efficiency, low operating costs, and low carbon emissions. With the implementation of sustainable development strategies and the continuous strengthening of energy conservation and environmental protection awareness, high-efficiency engines that use biomass or solar synthetic fuels to drive air The efficiency of the source heat pump is more than 1 times higher than that of the boiler. Independent heating does not have the phenomenon of cogeneration of heat and power in winter. It is an inevitable choice to replace the boiler or cogeneration. The engine-driven air source heat pump has signif...
