The air inlet of described gas engine is connected with gas pipeline, the output of described gas engine connects described Alternative Refrigerant Compressors, the outlet of described Alternative Refrigerant Compressors is connected with the import of described working medium condensing heat exchanger working medium side by gaseous working medium pipeline, the outlet of described working medium condensing heat exchanger working medium side is connected with the import of described choke valve by liquid refrigerant pipeline, the outlet of described choke valve is connected with the import of described working medium evaporating heat exchanger working medium side by pipeline, the outlet of described working medium evaporating heat exchanger working medium side is connected with the import of described Alternative Refrigerant Compressors by gaseous working medium pipeline,
The outlet of described working medium condensing heat exchanger water side is connected with the import of described floor heating equipment by heating feedwater piping, and the outlet of described floor heating equipment is connected with the import of described working medium condensing heat exchanger water side by heating water return pipeline.
The invention has the beneficial effects as follows:
The feature that gas-fired heat pump heats heating be heat supply temperature when lower the thermal efficiency high, and that the feature of floor heating is heat supply temperature is lower.The heating system that gas-fired heat pump provided by the present invention is combined with floor heating can be given full play to the feature of gas-fired heat pump and floor heating, further improves the heating efficiency of system.
Particularly, working medium saturation vapour pressure is relevant with temperature, and temperature is higher, and the pressure of heat pump fluid compression is higher, and the merit that compression consumes is more.Under general condition, heating hot water temperature on the impact of gas heat pump utilization ratio as table 1:
Table 1
| Heating hot water temperature/℃ | 35 | 40 | 45 | 50 | 55 | 60 | 65 | 70 |
