Abstract

The invention relates to the technical field of air conditioning systems, in particular to a multi-split air conditioning system which comprises an outdoor unit, an indoor unit and a fresh air ventilator. The outdoor unit is integrated with a compressor and a condenser, the compressor is of a double-suction-inlet design, and the outdoor unit is provided with a first suction inlet, a second suction inlet and an exhaust port; the first suction inlet communicates with a low-pressure cavity of the compressor, and the second suction inlet communicates with a medium-pressure cavity of the compressor; and the exhaust port is connected with the condenser, the indoor unit is connected with the first suction inlet of the compressor, the fresh air ventilator is connected with the second suction inlet of the outdoor unit, and the exhaust port is connected with expansion valves of the indoor unit and the fresh air ventilator. The operation energy efficiency of the multi-split air conditioning system is improved, so that the energy-saving performance of the multi-split air conditioning system is improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning systems, in particular to a multi-connected air conditioning system. Background technique [0002] With the development of economy and society and the improvement of people's living standards, people have higher and higher requirements for comfort in buildings. In the process of creating the indoor environment of a building, it is not only necessary to heat or cool the indoor air to meet the indoor temperature requirements, but also to deliver fresh air to the interior of the building to meet the human body's requirements for air freshness. The multi-connected air-conditioning system has been widely promoted and applied because of its simple installation and flexible use. [0003] During the use of the multi-connection + fresh air system, although the indoor unit handles indoor air and the fresh air blower handles fresh air (outdoor air), the temperature conditions of indoor air and fres...
