From refrigerant and the division board 111 of machine oil, the division board along input pipe Diameter distribution so as to by input pipe inside division into phase
The space up and down of connection.
The full-liquid type central air conditioner system for being provided with spiral evaporator of the present invention is illustrated in figure 2, wherein, including compressor
500th, condenser 200, external oil eliminator 300, low pressure recycle bucket 400 and spiral evaporator 100, the system of the compressor 100
Cryogen outlet connects the refrigerant inlet of external oil eliminator 300, the refrigerant outlet connection condenser of the oil eliminator 300
200 import, the refrigerant inlet of the outlet connection low pressure recycle bucket 400 of the condenser 200, the low pressure recycle bucket 400
Refrigerant outlet connection spiral evaporator 100 refrigerant inlet 112, the refrigerant outlet 121 of the spiral evaporator 100
It is connected with the air inlet of low pressure recycle bucket 400, the gas outlet of the low pressure recycle bucket 400 and the refrigerant inlet of compressor 500
Connection；Refrigerant gas after compressor compresses enters condenser condensation after the separation of external oil eliminator, freezes after condensation
Agent, which enters low pressure recycle bucket and further flowed into spiral evaporator, absorbs heat, and the refrigerant after heat absorption passes through from spiral evaporator
Air inlet is returned in low pressure recycle bucket, the refrigerator gas in low pressure recycle bucket by gas outlet enter compressor in formed it is next
Individual kind of refrigeration cycle.
Specifically, the full-liquid type central air conditioner system also includes being used for the machine oil storage tank 600 for storing machine oil, described external
Machine oil outlet on oil eliminator is connected with the import of machine oil storage tank, machine oil outlet and the machine on compressor of the machine oil storage tank
Oil-in connects.The other full-liquid type central air conditioner system also includes being used for the fluid reservoir 700 for storing refrigerant, described
The import of fluid reservoir and the outlet of condenser are connected, and the outlet of the fluid reservoir is connected with the refrigerant inlet of low pressure recycle bucket.
Entered by the refrigerant of external oil eliminator refrigerant outlet after condenser condenses in fluid reservoir.External oil eliminator energy
It is enough to be separated the mixed oil and gas after compressor, and the machine oil after separation is back in machine oil storage tank made for compressor
With, and the refrigerant gas isolated then sequentially enters warm condenser and low-temperature condenser carries out condensation cooling, the high temperature
Condenser and low-temperature condenser pass through cooling water condensation device（Do not mark）Cooling, the refrigerant after condenser enter fluid reservoir
Middle storage, and can at any time be passed into low pressure recycle bucket and participate in kind of refrigeration cycle.
Refrigerant used in the central air conditioner system of the present invention is freon.The effect of low pressure recycle bucket is will to be sent in fluid reservoir
After the refrigerant come is further cooled down by the air-breathing of main frame, with the method for gravity supply, it is fed in spiral evaporator and absorbs heat,
Gas after heat absorption is returned to low pressure recycle bucket and carries out further gas-liquid separation, and the gas after separation enters back into compressor, ensures
Compressor will not fall white.The low pressure recycle bucket set location is higher than spiral evaporator set location, makes in low pressure recycle bucket
Refrigerant enters spiral evaporator under gravity through refrigerant outlet.The central air conditioner system of the present invention changes freon
The traditional feed liquid way of refrigeration system, traditional expansion valve is substituted using gravity supply and supplies refrigeration, so as to solve traditional fluorine
Leon adds distributor to cause refrigerator pipes refrigeration to distribute unbalanced problem using expansion valve, can make the spiral evaporator of the present invention
Realize that complete equipilibrium is freezed, so as to substantially increase freon refrigeration efficiency, and saved electric energy.
The central air conditioner system kind of refrigeration cycle, which can be sketched, is：After central air conditioner system starts, the refrigerant in fluid reservoir enters
Enter into low pressure recycle bucket, and enter progress heat exchange in spiral evaporator along pipeline under gravity and become gaseous state, it is complete
Refrigerant into heat exchange returned in low pressure recycle bucket, refrigerant and the bucket top of liquid in low pressure recycle bucket now be present
Gaseous refrigerant, gaseous refrigerant is drawn into be compressed in compressor after enter in external oil eliminator, through external oil
Cooling in condenser will be passed into from device after the machine oil separation in gas and is condensed into liquid, is then gone through storage in fluid reservoir and is treated
Into next kind of refrigeration cycle, the machine oil that external oil eliminator is isolated is back to machine oil storage tank, and machine oil storage tank connects with compressor
Connect and supplement machine oil at any time for compressor.In kind of refrigeration cycle, it is because refrigerant enters spiral evaporator from low pressure recycle bucket
It is pumped into without traditional by Action of Gravity Field, therefore is steamed present invention saves energy consumption, while by Action of Gravity Field to spiral
The mode of hair device feed flow causes the evaporator in spiral evaporator to be in " full " state, and its high load capacity can be made to work, so as to
With high heat exchanger effectiveness so that the refrigeration efficiency of present system is significantly larger than traditional freon refrigeration system.
The spiral evaporator structure of the present invention is exactly to be designed further to improve the reliability of system operation, is preferably implemented
In example, the division board is fixed with the connection at input pipe both ends respectively by its both ends, the division board in horizontal positioned, its
The gap connected for upper and lower space is formed between two sides and input tube wall；The input pipe is connected by return line 113
Compressor is connected to, jet pump is provided with the return line, the machine oil deposited in the input pipe passes through jet pump along backflow
Pipeline enters compressor.
During the central air-conditioning work of the present invention, as refrigerant constantly enters spiral evaporator, precipitated in spiral evaporator
Machine oil it is also more and more, under the iris action of division board, machine oil can flow to the bottom of input pipe along division board both sides gap,
Therefore, in the input pipe of spiral evaporator, the machine oil proportion more and more higher of division board bottom, controlled in control system
Under, the machine oil under division board is drawn into return line 550 after injection pump startup, machine oil is back to compressor along return line
Middle participation kind of refrigeration cycle, and spiral evaporator due to eliminate machine oil sedimentation the drawbacks of, its also ensure that the present invention central hollow
Adjusting system remains good refrigeration efficiency, while overcomes conventional refrigeration and need machine oil is continuously replenished and cause system to transport
The drawbacks of row cost increase, substantially increase the reliability of system operation.
In preferred embodiment, the connector of the input pipe connection return line is arranged on the input being divided into by division board
On the lower space tube wall of pipe.
