Detailed description of the invention
Below by drawings and Examples, the technical solution of the utility model is described in further detail.
A kind of water that the utility model provides is as the centrifugal air conditioner group of cold-producing medium, as shown in Figure 2, comprise: be arranged on evaporimeter 5, compressor, motor and the condenser 6 in totally enclosed container 1, be arranged on first circulation canal being supplemented water as refrigerant by condenser 6 to evaporimeter 5 of container 1 outside, while the water as refrigerant that evaporimeter 5 can circulate at evaporation evaporimeter circulating pump 7, carry out exchange heat by the heat exchange mode of inner mediate contact and outside; Compressor under the driving of motor, can be sucked the water at low temperature steam of evaporimeter 5 generation, then is compressed by water at low temperature steam, then discharge high-temperature vapor by exhaust end by suction end; High-temperature vapor can be converted into water as refrigerant by the heat exchange mode of inner mediate contact by condenser 6.
Preferably, evaporimeter 5 and condenser 6 can be shell-tube type, mosquito-repellent incense disc type or plate type heat exchanger, have the advantage that heat exchange property is high.
Evaporimeter 7a, compressor and condenser 6a are installed on respectively in a container in prior art, are connected each other with pipeline, pipe diameter is less than the diameter (such as 0.5m) of evaporimeter 7a and condenser 6a, employing be semi-closed structure.But in compressor and evaporimeter 7a, the pipeline that connects between compressor and condenser 6a, the flow velocity of steam is too high, cause pressure drop excessive, make unit efficiency reduce, and the volume of whole unit is also larger.The utility model is compared with scheme of the prior art, evaporimeter 5, compressor and condenser 6 is arranged in a totally enclosed container 1, pipe diameter is the equal of the diameter (such as 2m) of the container 1 of whole unit, thus the flow resistance between compressor and evaporimeter 5, compressor and condenser 6 can be reduced, reduce the pressure loss, thus improve the Energy Efficiency Ratio of unit, can also pipeline be saved, and reduce the volume of air-conditioner set.These advantages all significantly can reduce the cost of air-conditioner set, promote its market potential.
The compression ratio that air-conditioner set will realize lower or medium time, in order to structure with simple to operately can only adopt a stage compressor to realize, when compression ratio is too high, employing single stage compress circulates, be not only uneconomic, and too high requirement is proposed to the performance of compressor, two stages of compression at this moment just can be adopted to circulate, reduce the compression ratio of single compressor, the following examples are all described for two stages of compression.
In an embodiment of the present utility model, compressor comprises stage compressor 2 and split-compressor 3, intercooler 11 is provided with between stage compressor 2 and split-compressor 3, the steam of the exhaust end discharge of stage compressor 2, after intercooler 11 cools, is sucked by the suction end of split-compressor 3; Intercooler 11 water as refrigerant used drives circulation by intercooler circulating pump 8, and supplements supply by condenser 6 by the second circulation canal.Wherein, intercooler 11 reduces the degree of superheat of the steam of being discharged by stage compressor 2, and water is evenly distributed in the surface of whole intercooler 11 packing material, and steam intersection flows through packing material, cooling water is flowed downward by it, is almost lowered to saturation temperature.Cooling can only be evaporated by the water section flow through in intercooler 11 and be realized, and the cooling water evaporated constantly is supplemented by the water as refrigerant circulation through condenser 6.
When stage compressor 2 is identical with the operating mode of split-compressor 3, as shown in Figure 2, a compressor motor 4 can be adopted two compressor Driven by Coaxial, and this mode can make the structure of air-conditioner set inside compacter, reduced volume, thus reduces costs.When stage compressor 2 is different with the operating mode of split-compressor 3, then need to carry out independent control, as shown in Figure 3, stage compressor 2 and split-compressor 3 are driven by stage compressor motor 41 and split-compressor motor 42 respectively, separately-driven mode controls more flexible, and can reach larger driving power.
In another embodiment of the present utility model, evaporimeter 5 is connected with user side 13, can make water as refrigerant while evaporation, be absorbed the heat of the chilled water of user side 13 by the heat exchange mode of inner mediate contact, thus obtaining the chilled water meeting certain temperature range, the user side 13 of supply air-conditioner set uses.Wherein, chilled water is equivalent to cold to be sent to from Air Conditioning Facilities the means of transport that user side 13 uses room.
