Embodiment 1

[0041] This embodiment provides an air conditioner capable of continuous heating, and the internal unit does not need to switch modes when defrosting. figure 1 It is a schematic structural diagram of the air conditioner capable of continuous heating provided by Embodiment 1 of the present invention, as shown in figure 1 As shown, the air conditioner includes: a compressor 1 , an outdoor heat exchanger 2 and a defrosting branch 3 .

[0042] One end of the defrosting branch 3 is connected to the discharge side of the compressor 1 , and the other end is connected to the outdoor heat exchanger 2 . The defrosting branch 3 is used to bypass part of the gaseous refrigerant discharged from the compressor 1 to the outdoor heat exchanger 2 for defrosting in the defrosting mode.

[0043] Specifically, one end of the defrosting branch 3 may be connected between the oil-air separator 51 and the four-way valve 52 , and the other end may be connected between the throttling device 54 and the o...

Embodiment 2

[0063] On the basis of the first embodiment above, this embodiment provides a method for controlling an air conditioner capable of continuous heating, which is applied to the air conditioner capable of continuous heating. Such as Figure 5 As shown, the method includes:

[0064] S501, it is detected that the defrosting condition is met, and the first flow rate of the gaseous refrigerant discharged by the compressor is controlled to flow into the outdoor heat exchanger through the defrosting branch for defrosting.

[0065] S502, controlling the second flow rate of gaseous refrigerant discharged from the compressor to flow into the indoor heat exchanger for heating.

[0066] When defrosting, the high-temperature and high-pressure gaseous refrigerant discharged from the compressor is divided into two parts. The first flow of gaseous refrigerant enters the outdoor heat exchanger through the defrosting branch to condense and defrost, and the second flow of gaseous refrigerant ente...

Embodiment 3

[0081] Based on the same inventive concept, this embodiment provides an air conditioner control device capable of continuous heating, which can be used to implement the method for controlling an air conditioner capable of continuous heating described in the above embodiments. The device can be realized by software and / or hardware, and generally the device can be integrated into the controller of the air conditioner. The unit includes:

[0082] The first control module is used to detect that the defrosting condition is met, and control the first flow of gaseous refrigerant discharged from the compressor to flow into the outdoor heat exchanger through the defrosting branch for defrosting;

[0083] The second control module is used to control the second flow of gaseous refrigerant discharged from the compressor to flow into the indoor heat exchanger for heating.

[0084] Specifically, the first control module is specifically configured to: turn on a switch on the defrosting bran...

Abstract

The invention discloses an air conditioner capable of heating continuously and a control method thereof. The air conditioner comprises a compressor, an outdoor heat exchanger and a defrosting branch circuit, one end of the defrosting branch circuit is connected to the exhaust side of the compressor, the other end is connected to the outdoor heat exchanger, and the defrosting branch circuit is usedfor bypassing a part of gas refrigerants discharged from the compressor to the outdoor heat exchanger for defrosting under a defrosting mode. The defrosting branch circuit is utilized to bypass a part of the high-temperature gas refrigerants discharged from the compressor to the outdoor heat exchanger for defrosting, the other part of the high-temperature gas refrigerants discharged from the compressor enters an indoor heat exchanger for heating, therefore it is ensured that an indoor unit continues heating in the defrosting process, it is ensured that the indoor environment temperature is stable, and uncomfortable experiences are avoided from being brought to users.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to an air conditioner capable of continuous heating and a control method thereof. Background technique [0002] When the air source heat pump is in heating operation, the outdoor heat exchanger acts as an evaporator, and its temperature is low. When the temperature is below zero and the outdoor environment has a certain humidity, frosting may occur on the outdoor heat exchanger. Frosting of the outdoor heat exchanger will lead to poor heat transfer performance of the heat exchanger, blockage of air circulation, and poor heating capacity of the unit. In serious cases, there will be no heating effect or even cold wind, poor user experience and even cause customer complaints. Therefore, when the unit is in heating operation, it will judge according to the operating status of the unit and timely defrost the unit to ensure the heating effect of the unit. [0003] When the exist...
