Problems solved by technology

The system is more complex, there are more equipment, and the initial investment is high
The cold and heat sources and terminals used for cooling in summer and heating in winter are different, and the utilization rate of system equipment is low
In addition, radiator heating requires high water temperature, and the efficiency of the system is extremely low in rainy and snowy weather when solar energy is insufficient, or even cannot operate

Abstract

The invention provides a heat pump air-conditioning system combining an air source heat pump with a small temperature difference heat exchange tail end, which has two different structures. The first structure comprises a system controller and component parts connected with the system controller respectively; and the second structure further comprises a condensation-evaporation device, a throttle, an evaporation-condensation device and a second condenser. Based on the air source heat pump and the small temperature difference heat exchange tail end, the two structures realize three different running modes as follows: a refrigeration mode that an air source water cooling and heating machine set is matched with the small temperature difference heat exchange tail end, a heating mode that the air source water cooling and heating machine set is matched with the small temperature difference heat exchange tail end, and a mode that domestic hot water is prepared by the air source water cooling and heating machine set. Through the utilization of the same set of system, the functions of effective refrigeration, heating and domestic hot water preparation are realized at the same time, and through utilization of the small temperature difference heat exchange tail end, the outlet water temperature of the air source water cooling and heating machine set in winter heating is reduced greatly, and the condensation temperature of the machine set is reduced, so that the energy efficiency ratios of the machine set and the system are improved.

Description

technical field [0001] The invention relates to the technical field of heat pump heating, in particular to a heat pump air conditioning system in which an air source heat pump is combined with a small temperature difference heat exchange terminal. Background technique [0002] With the improvement of people's living standards, the demand for heating in winter in southern regions with cold winter and hot summer is getting higher and higher. The current heating in the south mainly relies on split air conditioners, coal-fired gas furnaces and electric heating. Split air conditioners work inefficiently in winter when the outdoor temperature is too low. In addition, due to the small heat exchange area of ​​the indoor terminal, it is easy to cause uneven heating and a large indoor temperature gradient, and because the terminal installation position is generally closer to the top, hot air is easy to accumulate on the top. Coal-fired gas furnaces have high heating temperature, larg...
