Abstract

The invention provides a multi-split air conditioner and a control method thereof. The multi-split air conditioner comprises a compressor, an outdoor heat exchanger, a first indoor heat exchanger, a second indoor heat exchanger, a first air side pipe, a second air side pipe and a liquid side pipe, wherein the first air side pipe, the second air side pipe and the liquid side pipe all communicate between an indoor unit and an outdoor unit; and the multi-split air conditioner further comprises a four-way valve, a first control valve, a second control valve, a third control valve, a fourth controlvalve, a first pipeline, a second pipeline, a third pipeline and a fourth pipeline. According to the multi-split air conditioner, different indoor units in the multi-split system can effectively realize refrigeration and heating functions at the same time, the requirements of users for partial cooling and refrigeration and partial heating and temperature rise can be met, different requirements ofmultiple users are met, the usage scenarios of products are broadened, the universality and the applicability are higher, and the use comfort of the users is higher.

Description

technical field [0001] The present disclosure relates to the field of multi-connection technology, in particular to a multi-connection air conditioner and a control method thereof. Background technique [0002] Compared with young people, the elderly have lower tolerance to low temperature and high humidity, especially some elderly people are prone to diseases and are not suitable for recovery in low temperature or high humidity environments. During transitional seasons, it sometimes happens that the elderly's room needs to be heated or dehumidified, but other rooms need to be cooled. [0003] At present, the general multi-connected unit does not have the function of cooling and heating at the same time. This application discloses a multi-connected unit air conditioning system capable of heating and cooling at the same time, which can meet the situation that users need to perform cooling and heating at the same time in transitional seasons or special circumstances. .
