Problems solved by technology
[0003] However, the problem with the related technology is that when the operating frequency is increased to the reversing frequency of the four-way valve, it is easy to cause the temperature shutdown caused by the indoor temperature close to the temperature shutdown temperature, or the temperature of the indoor heat exchanger is close to the protection temperature. The high temperature protection shutdown of the indoor heat exchanger will not only cause the multi-line system to fail to return oil, but also affect the comfort of users

The invention discloses an air-conditioning system and a control method and control device of the air-conditioning system. The control method comprises the steps of when reversing control is conductedon a four-way valve of the air conditioning system, obtaining the running frequency of a compressor of the air-conditioning system; if the running frequency of the compressor is smaller than the reversing frequency of the four-way valve, obtaining temperature, indoor environment temperature and indoor setting temperature of an indoor heat exchanger of the air-conditioning system in real time; according to the indoor environment temperature and the indoor setting temperature, calculating the temperature difference between the indoor environment temperature and the indoor setting temperature; when it is determined that the temperature of the indoor heat exchanger is smaller than or equal to a first temperature threshold value and the temperature difference is smaller than or equal to a second temperature threshold value, controlling and raising the running frequency of the compressor to the reversing frequency of the four-way valve, and controlling the four-way valve to reverse when therunning frequency of the compressor reaches the reversing frequency of the four-way valve. Therefore, it is ensured that oil returning can be conducted normally under a heating pattern, and the userexperience is improved.
Description
technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a control method for an air conditioner system, a non-transitory computer-readable storage medium, a control device for an air conditioner system, and an air conditioner system. Background technique [0002] Related multi-line systems usually perform oil return control after running for a period of time. In related technologies, oil return control is mostly performed in cooling mode. If the current mode is heating mode, the operating frequency of the compressor is directly controlled to reach the reversing frequency of the four-way valve, and at the reversing frequency of the four-way valve, by controlling the four-way Reverse the through valve to switch the air conditioning system to cooling mode. [0003] However, the problem with the related technology is that when the operating frequency is increased to the reversing frequency of the four-way valve, it is ea...
