The company develops one kind based on the carbon dioxide heat pump sewage waste heat utilization heating system flow chart. The technical scheme is as follows: including sewage hot water heat exchanger, hot water circulating pump, electric valve, heat pump circulating pump, carbon dioxide heat pump and electric regulating valve, the first group of pipelines is provided with a hot water circulating pump and an electric valve. The second group of pipelines is provided with a heat pump circulating pump, a carbon dioxide heat pump and an electric control valve, the inlet of the carbon dioxide heat pump is communicated with a second water inlet tee of the second group pipeline through a heat pump circulation pump, and the outlet of the carbon dioxide heat pump is communicated with a second water outlet tee of the second group pipeline, an Electric Control Valve is connected between the second inlet tee and the second outlet tee. The beneficial effect is: the system flow can be heating through heat exchange, but also through heat pump unit and heat exchange combined operation heating, system energy saving effect is better, the flow is simpler.
