The invention provides a multi-connected air conditioning unit and a control method thereof. The multi-connected air conditioning unit comprises a first circulation system and a second circulation system. The first circulation system comprises a compressor, a first four-way valve, a first indoor heat exchanger, a first throttling component and a first outdoor heat exchanger. The second circulation system comprises a compressor, a second four-way valve, a second indoor heat exchanger, a second throttling component and a second outdoor heat exchanger. The four valve openings of the second four-way valve are connected with an air suction port of the corresponding compressor, an exhaust port of the corresponding compressor, the second outdoor heat exchanger and the second indoor heat exchanger respectively, and the second indoor heat exchanger is connected with the second outdoor heat exchanger through the second throttling component. According to the multi-connected air conditioning unit, the operation mode of the first circulation system and the operation mode of the second circulation system are changed by changing the connecting direction of the first four-way valve and the connecting direction of the second four-way valve, it can be achieved that the first circulation system and the second circulation system operate in different modes at the same time, and therefore the using demands of a user can be met.
Description
technical field [0001] The present invention relates to the technical field of multiple units, and more specifically relates to a multi-connected air conditioner unit and a control method thereof. Background technique [0002] Multi-connected air-conditioning units are gradually being widely used due to their advantages of energy saving and highly flexible use. [0003] In actual use, indoor requirements may be different, requiring different indoor units to operate in different modes at the same time, for example, cooling is required in one room and heating is required in another room. However, for multi-connected air-conditioning units, all indoor units can only operate in the same mode, that is, all indoor units operate in cooling mode or in heating mode, resulting in multi-connected air-conditioning units that cannot meet user requirements . [0004] To sum up, how to provide a multi-connected air conditioner unit so that different indoor units can operate in different ...
