[Abstract]:The application of air source heat pump floor heating system to residential heating in hot summer and cold winter area has been the trend of the times, but some problems have been encountered in practical application. Therefore, this paper has carried on the experimental research to the air source heat pump floor heating system, has understood the air source heat pump unit movement characteristic and the system heating effect, The problems encountered in practical application and the matching problem between air source heat pump and floor heating are analyzed in detail. The energy saving and economy of air source heat pump floor heating system are also analyzed. It is suggested that air source heat pump should be used instead of gas wall hanging furnace as heat source for floor heating. This paper first points out that the air source heat pump floor heating system provides a good idea for residential heating in hot summer and cold winter area. Using air source heat pump as cooling and heat source, the system not only solves the need of air conditioning cooling in summer, but also provides low temperature hot water for floor heating in winter. The research status of air source heat pump floor heating system at home and abroad is also analyzed in this paper. Secondly, the test bench of air source heat pump floor heating system is built, and the system is tested under different weather, different water supply mode and different flow rate, and the operation characteristics and rules of the system are grasped. The experimental results show that the heating effect of air source heat pump floor heating system is good, and the system performance is affected by many factors. The experimental research provides the direction for the optimization design of air heat pump floor heating system. Then, it is pointed out that the optimization of air source heat pump floor heating system has great energy saving potential. On the one hand, it is necessary to ensure the stability of the system, on the other hand, to optimize the matching of air source heat pump and floor heating. In this paper, the frequent start-up problem and defrosting problem of the unit are analyzed according to the operating characteristics of the system, and a suitable and reliable control method is put forward according to the characteristics of the system. This paper also analyzes the matching of floor heating and different heat sources from the aspects of water temperature, flow rate and heat dissipation. For the gas wall hanging furnace floor heating system, the system adopts small flow rate, high temperature hot water to heating, floor heating coil tube spacing can meet the requirements; but for air source heat pump floor heating system, The system uses large flow, low temperature hot water to heating, floor heating coil space is small to meet the requirements. Finally, the energy efficiency and economy of the air source heat pump floor heating system are analyzed and compared with the gas wall hanging furnace floor heating system. It is concluded that although the initial investment of air source heat pump floor heating system is slightly higher than that of gas wall hanging furnace floor heating system, it has the characteristics of low operating energy consumption and low annual operating cost, so it is worth popularizing and using. At the same time, the COP of air-source heat pump unit has great influence on the running energy consumption and cost, so it is necessary to improve the COPof air-source heat pump unit.
