Application status and prospect of residential heat pump heating technology in the Yangtze River Basin

In recent years, the demand for heating of residential buildings in the Yangtze River Basin has been increasing, and the related heating technology has been paid more attention. Based on the climatic characteristics, building envelopes and heating characteristics of the Yangtze River Basin and focused on residential buildings, comprehensively analyses the common single heat source heat pump heating mode, the composite heat source heat pump heating mode and heating terminal forms. Considers that the household air-source heat pump heating is a shortcut to solve the residential heating problem in the Yangtze River Basin, the energy tower heat pump is an important way of heating in small region, and the multiple heat source compound heating is the development direction. In cities and towns, energy saving and efficient small district central heating should be the main heating way, supplemented by household heating. In rural areas, clean energy heating technology should be adopted in accordance with local conditions to make full use of the water and ground sources in the Yangtze River Basin. It is necessary to develop the composite heat source heating system to improve its energy saving, heating efficiency and economical efficiency. The radiant terminal has excellent comfort and energy saving, which is a suitable and perfect heating terminal form. The building energy saving technology should be developed together with the heating technology.
