Indication or suggestion described device or element must have a particular orientation, be constructed and operated in a specific orientation, therefore cannot manage
Solution is limitation of the present invention.
In addition it is also necessary to explanation, in the description of the present invention unless specifically defined or limited otherwise, term " is set
Set ", " connected ", " connection " shall be understood in a broad sense, for example, it may be being fixedly connected, may be a detachable connection, or integrally
Connection；It can be mechanical connection, be also possible to be electrically connected；Can be directly connected, can also indirectly connected through an intermediary,
It can be the connection inside two elements.To those skilled in the art, it can understand that above-mentioned term exists as the case may be
Concrete meaning in the present invention.
Using the problem that screw compressor efficiency is not high in the existing air conditioner pointed out based on background technique, the present invention is mentioned
A kind of air conditioner is supplied, it is intended to improve the efficiency of cooler compressor.
Specifically, as shown in Figure 1, air conditioner of the invention includes evaporator 1, condenser 2, magnetic suspension compressor 3, evaporation
The gaseous refrigerant outlet of device 1 is connect by pipeline with butterfly valve 4, and butterfly valve 4 passes through air inlet side reducer pipe 5 and magnetic suspension compressor 3
Air inlet connection, the exhaust outlet of magnetic suspension compressor 3 connect with exhaust side reducer pipe 6, exhaust side reducer pipe 6 and check valve 7
Connection, check valve 7 are connect by pipeline with the gaseous refrigerant inlet of condenser 2, and the liquid refrigerant outlet of condenser 2 passes through
Pipeline is connect with filter 8, and filter 8 is connect by pipeline with electric expansion valve 9, and electric expansion valve 9 passes through pipeline and evaporation
The liquid refrigerant inlet of device 1 connects, in addition, liquidometer 10 is provided on condenser 2, for measuring the liquid level in condenser 2.
Air inlet side reducer pipe 5 is set as being gradually reduced along refrigerant flow direction, and the caliber of exhaust side reducer pipe 6 is set as along refrigerant
Flow direction is gradually increased.That is, the miner diameter end (outlet end) of air inlet side reducer pipe 5 is connect with the air inlet of compressor,
The miner diameter end (arrival end) of exhaust side reducer pipe 6 is connect with the exhaust outlet of compressor.Wherein, air inlet side reducer pipe 5 and exhaust side
Reducer pipe 6 can use two-stage reducer pipe, and certainly, air inlet side reducer pipe 5 and exhaust side reducer pipe 6 can also use three-level variable diameter
Pipe.Those skilled in the art can flexibly set the knot of air inlet side reducer pipe 5 and exhaust side reducer pipe 6 in practical applications
Structure, as long as can be improved the efficiency of magnetic suspension compressor 3 by air inlet side reducer pipe 5 and exhaust side reducer pipe 6.It needs

It talks about, inlet and outlet nominal diameter difference second level is known as second level variable diameter, and the three-level that is known as of inlet and outlet nominal diameter difference three-level becomes
Diameter.
In the present invention, it is illustrated by exhaust side second level reducer pipe of exhaust side reducer pipe, essence plays diffusion
Effect, specifically, high-pressure gaseous refrigerant from the exhaust outlet of magnetic suspension compressor high speed flow out after the row of entering directly into
In the second level reducer pipe of gas side, with being gradually increased for diameter, the circulation area in pipe is consequently increased, and the speed of gas gradually drops
Low, the kinetic energy of high-speed gas is converted into static energy at this time, to achieve the purpose that improve pressure.Repeatedly tested by inventor,
It analyzes and compares, in traditional compressor, when the inlet pressure (i.e. the exhaust outlet of compressor) of exhaust side reducer pipe is
When 800kpa, the outlet pressure of exhaust side reducer pipe is 790kpa or lower, and drag losses are 10kpa or more, and in this hair
The bright middle design using magnetic suspension centrifugal compressor and second level reducer pipe, when exhaust side second level reducer pipe inlet pressure (i.e.
The exhaust outlet of compressor) be 790kpa when, the outlet pressure of exhaust side reducer pipe can reach 800kpa, that is, increase 10kpa,
In this way, that is, centrifugal compressor diffuser principle is utilized, so that the inlet pressure of compressor is lower, to reach raising energy
The purpose of effect.By comparison it is found that in the case where condensation temperature is certain, using magnetic suspension centrifugal compressor of the invention and
The efficiency of corresponding variable diameter design will be apparently higher than the efficiency of traditional compressor design, i.e., the energy-saving effect of air conditioner of the invention
More preferably.
