Flow into indoor heat converter 60A, 60B, the refrigerant of 60C and room air carry out heat exchange, become the gaseous state of low temperature/low pressure afterwards and contain liquid mixing refrigerant.When refrigerant is flowed through fluid reservoir, have only the refrigerant of gaseous state to be transported to compressor 10A, 10B and constitute a circulation of refrigerant.
When air-conditioner as above heated running, the flow direction of its refrigerant and the effect that heat exchanger played were just in time opposite.That is the refrigerant that is compressed by the compressor fluid reservoir → indoor heat converter → expansion valve → outdoor heat converter of flowing through successively.
Summary of the invention
Technical problem to be solved by this invention is that a kind of off-premises station that reduces the multi-split air conditioner of coolant noise and compressor vibrations is provided.
In order to solve the problems of the technologies described above, the technical solution used in the present invention is: a kind of off-premises station of multi-split air conditioner is provided with a compressor air suction silencer between the air inlet of the outlet of evaporimeter and compressor.
Described compressor air suction silencer constitutes for the muffler of differential concatenation by two, the air inlet pipe of forward muffler is connected on the evaporator outlet, the escape pipe of forward muffler links to each other with the escape pipe of reverse muffler, and oppositely the air inlet pipe of muffler is connected on the air inlet of compressor.
The invention has the beneficial effects as follows: when air conditioner heat-production turns round, when a compressor only drives an indoor set operation, forward muffler in the compressor air suction silencer plays the effect that reduces coolant noise, and oppositely muffler plays the effect that reduces the compressor vibrations.
