The invention belongs to the technical field of heat pumps, and particularly relates to an energy storage type air source heat pump system. The system comprises a compressor, an indoor heat exchanger, a first throttling mechanism, an outdoor heat exchanger, a reversing valve and a phase change accumulator. A first regulating valve is arranged on a pipeline between the reversing valve and the outdoor heat exchanger. A second regulating valve is arranged on a pipeline between the reversing valve and the indoor heat exchanger. A first end of the phase change accumulator communicates with a pipeline between the first regulating valve and the reversing valve through a first pipeline. A second end of phase change accumulator communicates with a pipeline between the second regulating valve and the reversing valve through a second pipeline. The first pipeline and the second pipeline are provided with a third regulating valve and a fourth regulating valve correspondingly. A pipeline between the first throttling mechanism and the outdoor heat exchanger communicates with a pipeline between the fourth regulating valve and the second end of the phase change accumulator through a third pipeline. A pipeline between the first throttling mechanism and the indoor heat exchanger communicates with a pipeline between the third regulating valve and the first end of the phase change accumulator through a fourth pipeline. The energy storage type air source heat pump system improves energy efficiency and has an important meaning for energy conservation.
Description
technical field [0001] The invention belongs to the technical field of heat pumps, in particular to an energy storage type air source heat pump system. Background technique [0002] The air source heat pump has the advantages of using inexhaustible air as a low-level heat source, wide application range, and high equipment utilization rate. However, the characteristics and operation practices of air source heat pumps also show that: (1) the energy efficiency of air source heat pumps in winter is high when the outdoor air temperature is high during the day, and the energy efficiency is low when the outdoor air temperature is low at night; The energy efficiency is low when the temperature is high, and the energy efficiency is high when the outdoor air temperature is low at night, which is just opposite to the energy load of the building. The heating performance of the air source heat pump is contrary to the change of the building load with the outdoor temperature. (2) Suscepti...
