The beneficial effects of the utility model are: working medium vapo(u)rization system of the present utility model, can reclaim the heat that adds the carbon dioxide working medium behind the hot water by waste-heat recoverer, evaporate by evaporimeter again, and an independent loops loop in conjunction with the defrost heat exchanger, for the working medium vapo(u)rization system is brought enough heats, prevent locking system frost, and realized effective utilization of heat energy.
Description of drawings
Further specify below in conjunction with the drawings and specific embodiments:
Fig. 1 is a system architecture schematic diagram of the present utility model.
The specific embodiment
As shown in Figure 1, the working medium vapo(u)rization system of a kind of carbon dioxide heat-pump hot water facility provided by the utility model, comprise evaporimeter 1, also comprise waste-heat recoverer 2, defrost heat exchanger 3 and be used to absorb the defrost heat-exchanger rig 4 of heat, wherein waste-heat recoverer 2 inputs connect carbon dioxide working medium input pipe 51, output is connected by the input of pipeline with evaporimeter 1, and throttling arrangement 11 can be set on pipeline, flow with control carbon dioxide working medium, the output of evaporimeter 1 connects carbon dioxide working medium efferent duct 52, promptly formed the carbon dioxide working medium after water is heated, at first by carbon dioxide working medium input pipe 51 input waste-heat recoverers 2, enter evaporimeter 1 afterwards, the start vaporizer heat absorption, export to the carbon dioxide compressibility by carbon dioxide working medium efferent duct 52 at last, recompress the high temperature refrigerant that formation needs, to continue to add hot water; Stating defrost heat exchanger 3 is arranged between waste-heat recoverer 2 and the evaporimeter 1, and be connected with defrost heat-exchanger rig 4 by anti-icing fluid circulating line 31, form the anti-icing fluid closed circuit, this loop can absorb far-end or other local heats by the anti-icing fluid in the defrost heat-exchanger rig 4, pass to defrost heat exchanger 3, and because defrost heat exchanger 3 is the position relation that is adjacent to evaporimeter 1, necessary heat can when absorbing heat, be provided in the evaporation of the carbon dioxide in the evaporimeter 1, to prevent frost, and as preferred embodiment, defrost heat-exchanger rig 4 can be arranged in the water storage system 7 of heat-pump hot-water equipment, directly the heat of drawing hot water in the water storage system 7 uses, get final product because of defrost heat exchanger 3 only need guarantee evaporimeter 1 frost-free, so hot water temperature to be supplied influences not quite in 4 pairs of water storage systems 7 of defrost heat-exchanger rig; For guaranteeing loop circulation and corresponding control smoothly, necessary parts such as filter 33, circulating pump 34 and water flow switch 35 can be set on anti-icing fluid circulating line 31 in addition.
