As shown in Figure 1, a kind of ice storage central air-conditioning device of the present invention, including for by the compressor 1 of cold-producing medium that the refrigerant compression of gaseous state is liquid, what be connected with described compressor 1 carries out heat exchange for the cold-producing medium and lubricating oil that compressor flows out liquid and obtains the cold-producing medium of the liquid of High Temperature High Pressure and the condenser 2 of lubricating oil, the cold-producing medium of the liquid being used for throttling as low-temp low-pressure cold-producing medium and the lubricating oil of the liquid of High Temperature High Pressure being connected with described condenser 2 and the expansion valve 3 of lubricating oil, also include connecting with described compressor 1 and described expansion valve 3 respectively for making refrigerant air-liquid separate, and by the cold-producing medium of gaseous state, lubricating oil is recycled to the gas separation unit 4 of compressor 1, and the Ice storage coiled pipe 5 for ice-reserving being connected with described gas separation unit 4.Described cold-producing medium is freon, and wherein in gas separation unit 4 and Ice storage coiled pipe 5, all storage has liquid freon.
The central air conditioning plant of prior art is mostly compressor 1, condenser 2, expansion valve 3 is sequentially connected with, and is user's refrigeration by multiple branched pipes. But the central air-conditioning in building often occurs not having freon to flow through in branched pipe, or freon phenomenon pockety so that some configured branched pipe does not have freon to circulate, and causes structure to waste. Owing to branched pipe is not fully utilized, the more freon quantity of steam that can produce again of unnecessary branched pipe quantity reduces, and namely the flow velocity of freon reduces so that freon liquefaction condensation effect weakens, liquid freon can not be supplemented in time, thus easily causing compression machine burning machine phenomenon for compressor. Lubricating oil is more difficult after flowing out from compressor with the cold-producing medium of liquid simultaneously refluxes from other devices, it is impossible to easily cause burning machine phenomenon for compressor make-up oil in time.
The present invention is provided with a gas separation unit 4 between described compressor 1 and described expansion valve 3, is then connected with Ice storage coiled pipe 5 by described gas separation unit 4 further through a cryopump, and described Ice storage coiled pipe 5 is connected with branched pipe again and provides the user cold air. Freon gas and freon liquid can be easily separated by described gas separation unit 4, it is possible to resolve the problem that the more freon steam of above-mentioned branched pipe quantity cannot uniformly circulate, and Central air-conditioning unit can be made to make full use of freon and branched pipe. Lubricating oil, gas separation unit 4, can be recycled to compressor 1 by the cold-producing medium of gaseous state by the lubricating oil simultaneously flowed out from compressor 1, it is to avoid burning machine occurs compressor 1.
Concrete, as in figure 2 it is shown, be provided with the first U-tube 41 and the second U-tube 42 in described gas separation unit 4, and described first U-tube 41 and interlaced and vertical being arranged in described gas separation unit 4 of the second U-tube 42.
Compressor 1 is by the freon boil down to liquid freon of gaseous state, then the liquid freon of High Temperature High Pressure is become after delivering to condenser 2 heat exchange with lubricating oil, subsequently into expansion valve 3, suddenly the freon pressure reduction made is increased owing to freon enters expansion valve 3 rear space, the freon vaporization of the liquid of High Temperature High Pressure becomes the freon (i.e. freon steam) of the liquid of low-temp low-pressure, and the low temperature freon of liquid will absorb the indoor substantial amounts of heat of user and freeze for user. In the present invention, ice storage central air-conditioning device is then utilize electricity consumption rule round the clock, it is used for storing cold energy by the electricity of relatively low for civil power electricity charge period in advance, or the cold energy utilizing Central air-conditioning unit superfluous stores, when civil power demand is bigger, the cold energy of storage is released to people and cold air is provided, save the energy. In the present invention, Ice storage coiled pipe 5 is namely for the device of ice-reserving, and this Ice storage coiled pipe 5 can connect 3000 branched pipes provides cold air for the user in building.

The present invention arranges a gas separation unit 4 between Ice storage coiled pipe 5 and expansion valve 3, expansion valve 3 output gaseous state and liquid mixing freon and lubricating oil. Lubricating oil sinks to bottom in gas separation unit 4, and the freon of liquid floats over above lubricating oil, and freon steam is then above the freon of liquid. When the freon of liquid is flowed into Ice storage coiled pipe 5 by cryopump 6, then heat absorption becomes the freon of gaseous state. The freon of gaseous state is back to gas separation unit 4 from Ice storage coiled pipe 5, by the freon of gaseous state, the lubricating oil band bottom gas separation unit 4 is back to compressor 1.Liquid fluorine Leon is stored in described gas separation unit 4, and the freon of gaseous state is then flowed back in compressor 1 by gas separation unit 4. Described Ice storage coiled pipe 5 is connected with described gas separation unit 4 by a cryopump 6, when the freon deficiency of the liquid in described Ice storage coiled pipe 5, freon liquid in gas separation unit 4 can be pumped in Ice storage coiled pipe 5 by described cryopump 6 so that it is continue ice-reserving storage cold energy.

The present invention offers at least one for making the lubricating oil of liquid bottom described gas separation unit 4 flow to the return port 45 of described second U-tube in the second U-tube 42 bottom side, it is advantageous to offer 3 return ports 45. Owing to being lubricating oil bottom gas separation unit 4, so lubricating oil can pass through this return port 45 and enter in the second U-tube 42. Again because the first U-tube 41 and the second U-tube 42 carry out the exchange of gaseous fluorine Leon in gas separation unit 4, the lubricating oil entered in the second U-tube 42 can be brought in compressor 1 by the gaseous fluorine Leon with certain flow rate, thus it is not enough to utilize the liquid freon in gas separation unit 4 to come freon and lubricating oil when make up compressor 1 runs, thus solve the problem that compressor 1 produces burning machine because of freon and lubricating oil deficiency.
Further, described return port 45 diameter is not less than 4mm, and comparatively preferred described return port 45 diameter range is at 4-10mm.
