However, during heating operation, if the indoor heat exchanger 60C of one indoor unit is working and the indoor heat exchanger 60B of the other indoor unit is not working, but at this time the solenoid valve 11C is open, and the solenoid valve 11B is also in the open state. That is to say, although the indoor heat exchanger 60B is not working, there is still refrigerant flowing in the indoor heat exchanger 60B, and the noise of the compressor is transmitted to the indoor heat exchanger 60B of the non-working indoor unit through the pipeline, causing an abnormality noise

Embodiment Construction
[0023] Below in conjunction with accompanying drawing and specific embodiment the present invention is described in further detail:
[0024] The operating principle of the air conditioner of the present invention is the same as that of the prior art, and the prior art can be referred to, so it will not be described again. The difference between the present invention and the prior art is the addition of a compressor suction muffler, which will be described in detail below illustrate:
[0025] Such as image 3 As shown, the outdoor unit 1 of the one-driver-multiple air conditioner of the present invention includes compressors 10A, 10B and an outdoor heat exchanger 30, etc.; the indoor unit 50 includes indoor heat exchangers 60A, 60B, 60C, and expansion valves.
[0026] In a one-to-many air conditioner, multiple indoor units 50 are connected to one outdoor unit 1, and the outdoor unit 1 and the indoor units 50 are respectively connected through a high-pressure pipe with high pre...

The invention discloses an outdoor unit of a multi-split air conditioner. A compressor air suction silencer is arranged between the outlet of an evaporator and the air inlet of a compressor. The compressor air suction silencer consists of two reverse series silencers, the air inlet pipe of the forward silencer is connected on the outlet of the evaporator, the air outlet pipe of the forward silencer is connected with the air outlet pipe of the reverse silencer, and the air inlet pipe of the reverse silencer is connected on the air inlet of the compressor. When the air conditioner runs to heat and the compressor only drives one indoor unit, the forward silencer in the compressor air suction silencer plays a role in reducing the noise of a coolant, and the reverse silencer plays a role in reducing the vibration of the compressor.
Description
technical field [0001] The invention relates to an air conditioner, in particular to an outdoor unit of a one-driver-multi-air conditioner which reduces vibration of compressors. Background technique [0002] Generally speaking, an air conditioner is a cooling / heating system that repeatedly inhales hot air in a room, exchanges heat with a low-temperature refrigerant, and then discharges it into the room to cool the room, or heat the room in the opposite way. It is a machine consisting of a series of cycle systems consisting of compressor-condenser-expansion valve-evaporator. [0003] In addition to cooling / heating, recent air conditioners are increasingly equipped with an air purification function that sucks indoor polluted air, filters it, and discharges clean air to the room, and dehumidifies humid air before releasing it to the room. The dehumidification function and many other additional functions. [0004] Air conditioners can be roughly classified into a separate typ...
