Problems solved by technology

The thermal storage and defrosting method adopted by the air conditioning circulation device in the prior art is that the suction end of the compressor merges two parts of refrigerant: one part is the refrigerant that passes through the indoor unit and then the heat storage tank; the other part is the refrigerant that defrosts the outdoor unit, The two streams of refrigerants meet at the suction end of the compressor and return directly to the compressor. At this time, the refrigerant is likely to cause liquid in the suction of the compressor, which will cause wear and tear. In addition, the two-part flow is not easy to control, and the heat of the indoor mechanism is directly affected.

Abstract

The invention provides an air conditioning system being able to achieve continuous heating; a compressor, a switching device, an outdoor heat exchanger, a throttle element and an indoor heat exchanger are sequentially connected in order to form a refrigeration loop; a heat accumulation device is cascaded between the first end of the throttle element and the switching device; the second end of the throttle element is communicated with the outdoor heat exchanger; the air conditioning system has a first heating mode and a second heating mode; under the first heating mode, the refrigerant discharged by the compressor sequentially enters the indoor heat exchanger, the throttle element, and the outdoor heat exchanger via the switching device; under the second heating mode, the refrigerant discharged by the compressor passes through the switching device, one path thereof enters the indoor heat exchanger, the other path enters the outdoor heat exchanger; the refrigerant flows out from the outdoor heat exchanger and the indoor heat exchanger enters an air suction end of the compressor via the heat accumulation device. The air conditioning system being able to achieve continuous heating enables the heat pump air conditioner to heat continuously while the air conditioner is working to heat; the flux of refrigerant flows into the indoor heat exchanger and the outdoor heat exchanger are easier to be distributed.

Description

technical field [0001] The invention relates to the refrigeration field, in particular to an air-conditioning system capable of realizing continuous heating. Background technique [0002] Thermal storage and defrosting is a new technology in the field of heating research and product promotion in the industry. The thermal storage and defrosting method adopted by the air conditioning circulation device in the prior art is that the suction end of the compressor merges two parts of refrigerant: one part is the refrigerant that passes through the indoor unit and then the heat storage tank; the other part is the refrigerant that defrosts the outdoor unit, The two streams of refrigerant merge at the suction end of the compressor and return directly to the compressor. At this time, the refrigerant is likely to cause liquid in the compressor suction, which will cause wear and tear.
