The invention provides a multi-split air conditioner and a control method thereof. The multi-split air conditioner comprises a compressor unit, an outdoor heat exchanger, a first pipe, a second pipe,a third pipe and a fourth pipe, wherein the first pipe, the second pipe, the third pipe and the fourth pipe all communicate between an indoor unit and an outdoor unit; the multi-split air conditionerfurther comprises a first four-way valve, a second four-way valve and a third four-way valve; the second end of the first four-way valve communicates with the outdoor heat exchanger, and the other endof the outdoor heat exchanger can communicate with the first pipe; and the second pipe and the fourth pipe communicate with each other and then communicate to the seventh end of the second four-way valve together, and the third pipe can communicate with the tenth end of the third four-way valve. According to the multi-split air conditioner, the problems that a three-pipe air conditioner control system is poor in practicability, and the efficiency of an indoor unit heat exchanger is not fully utilized are solved under the multiple modes of refrigeration, heating, refrigeration and water heating, heating and water heating, water heating and heating and the like.
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] The modular full-function multi-split unit is a new generation of multi-split unit that integrates cooling, heating, floor heating, and hot water heating. It can realize multiple functions at the same time, so that one machine can be used for multiple purposes, and there are very few such products on the market at present, so there is still a great development prospect. But to achieve multi-function, it means that it has a complex control system, such as series-parallel combination control of compressors, four-way valve, double four-way valve control, various valve body combination control and pipeline system control, etc. These Both make the structure and control system of the unit extremely complicated, and bring great difficulties to the design, development and la...
