and the heat storage medium of the heat storage device 11 is positioned at the periphery of the compressor 1 and is used for absorbing the residual heat generated by the compressor 1.
In the above embodiment, a scheme for effectively improving the energy utilization rate of the air conditioning unit is provided, in which a heat storage device is disposed at the compressor, and waste heat generated by the compressor is absorbed by the heat storage device, so that the waste heat collected by the heat storage device can be reused. Through above-mentioned heat accumulation device, store waste heat and release when needing, improved energy utilization, have energy saving and emission reduction's effect, effectively solved the problem that energy utilization is low among the prior art.
And simultaneously, the utility model provides a heat accumulation device 11's heat accumulation medium is located compressor 1's periphery, and is preferred, and the heat accumulation medium directly surrounds in compressor 1's the outside to improve heat absorption's efficiency, the heat source quality who obtains is higher.

In general, an air conditioning system cannot perform heating when defrosting, and needs to be switched to a cooling mode to defrost an outdoor heat exchanger. The arrangement of the bypass branch can defrost the outdoor heat exchanger under the condition that the system does not switch the heating operation mode, so that the indoor heat working condition is more stable.
The bypass branch includes: and the electromagnetic valve 6 is used for controlling the refrigerant flow of the bypass branch. And a second restriction element 7 located between the discharge port of the compressor 1 and the solenoid valve 6.
The heat accumulation branch comprises: and the inlet of the one-way valve 8 is connected with the heat storage device 11, and the outlet of the one-way valve 8 is connected with the four-way valve 2. The heat storage branch is connected with the four-way valve 2 and the outdoor heat exchanger 3 through a three-way valve 9; the three-way valve 9 is used to connect the four-way valve 2 to communicate with the outdoor heat exchanger 3 in the cooling mode and to communicate the heat storage device 11 with the outdoor heat exchanger 3 in the heating mode. Further, the heat accumulation branch also comprises: a third throttle element 10 is located between 11 and the three-way valve 9.
Fig. 1 also shows a refrigerant flow path and a defrosting refrigerant flow path in the heating mode, and as shown in fig. 1, when defrosting of the outdoor heat exchanger 3 is required in the heating mode, the flow path of the three-way valve 9 is turned downward (downward in fig. 1), the electromagnetic valve 6 is opened, and the first throttling element 4 is fully opened (i.e., not throttled). The first restriction element 4 may be an electronic expansion valve. After the refrigerant comes out from the exhaust port of the compressor 1, the refrigerant is divided into two paths, one path circulates according to a heating loop, the other path throttles firstly, then passes through the electromagnetic valve 6 and then is converged with the refrigerant flowing through the indoor heat exchanger 5, and then defrosting is carried out on the outdoor heat exchanger 3. At this time, the refrigerant having a high temperature can obtain a good defrosting effect, and the refrigerant flowing through the outdoor heat exchanger 3 passes through the three-way valve 9, flows downward, is throttled by the third throttling element 10, absorbs heat in the heat storage device 11, and returns to the compressor 1, thereby completing the circulation.
The opening degree of the first throttling element 4 is fully opened, defrosting can be completed without bypassing more heat, and therefore indoor comfort is better. The third throttling element 10 throttles and then enters the compressor 1 through the heat storage device 11 and the four-way valve 2, so that the phenomenon that the temperature of the defrosted refrigerant is too low to enter the compressor 1 is avoided. By means of the scheme, the defrosting is completed, and meanwhile, the indoor comfort is effectively improved.
Meanwhile, the opening degree of the electromagnetic valve 6 can be controlled in the defrosting process, so that the defrosting speed is accelerated. The specific control can be regulated and controlled through the change rate of the indoor environment temperature bulb.
