Abstract

The utility model discloses a compact evaporative cooling and mechanical refrigeration composite air conditioning unit consisting of three-stage units, i.e. an indirect coil pipe, a direct evaporation cooler and a refrigerant direct expansion air cooler, which comprises the indirect coil pipe and a direct evaporation cooler and further comprises a compressor, a refrigerant direct expansion air cooler and an air feeder which are arranged behind the direct expansion air cooler along the air supply direction as well as a condenser and an air exhaust fan which are arranged behind the direct expansion air cooler in the order of air exhaust, wherein, the condenser, the refrigerant direct expansion air cooler and the compressor form a closed loop through a pipeline. The compact three-stage unit formed through the structure can save the indoor occupied space or reduce the roof load and can provide high-quality, energy-saving cold air for buildings in summer.

Description

Compact evaporative cooling and mechanical refrigeration combined air conditioner unit
Technical field
The utility model belongs to the air conditioner refrigerating technical field, relates to a kind of air-conditioning unit, is specifically related to a kind of compact evaporative cooling and mechanical refrigeration combined air conditioner unit.
Background technology
The Evaporative Cooling Air Conditioning unit is applied in areas such as NORTHWEST CHINA Xinjiang at present with its advantages of energy saving and environmental protection.But this unit is subjected to the restriction of outdoor climate conditions bigger, and is only comparatively suitable for dry area.And for vast middle humidity area or high humility area,, be implemented in high temperature to utilize evaporation cooling technique that new wind is carried out precooling hot season if evaporation cooling technique is combined with traditional mechanical refrigeration, after again through the mechanical refrigeration cooling processing; And a large amount of transition seasons use evaporative cooling to reach the purpose of regulating air separately, can give full play to evaporative cooling and mechanical refrigeration advantage separately.So both air-conditioning unit energy consumption can be saved greatly, cold-producing medium CFCS and HCFC working medium can be reduced simultaneously the destruction of ozone layer generation and the generation that causes greenhouse effects.Thereby the needs of humidity area and even high humility area air-conditioning play positive facilitation to the energy-saving and emission-reduction work of China in satisfying.
Summary of the invention
The purpose of this utility model provides the Evaporative Cooling Air Conditioning unit that a kind of evaporative cooling combines with mechanical refrigeration, with aerial cooler as indirect evaporation cooler, Cold water supply indirect evaporation cooler with the direct evaporative cooler generation, indirect evaporation cooler, direct evaporative cooler and mechanical refrigeration surface cooler are closely constituted the Evaporative Cooling Air Conditioning unit, save and take up an area of the space, can provide comfortable cold wind for building in summer.
The technical scheme that the utility model adopted is, compact evaporative cooling and mechanical refrigeration combined air conditioner unit, form by indirect coil pipe, direct evaporative cooler and three grades of units of cold-producing medium direct expansion formula aerial cooler, comprise indirect coil pipe and direct evaporative cooler, also comprise the compressor, cold-producing medium direct expansion formula aerial cooler and the pressure fan that behind direct evaporative cooler, set gradually by air supply direction; By condenser and the exhaust blower that the air draft direction sets gradually, constitute a closed-loop path by pipeline between condenser, cold-producing medium direct expansion formula aerial cooler and the compressor behind direct evaporative cooler.
Characteristics of the present utility model also are,
Be provided with water fender between condenser and the exhaust blower.
Be provided with expansion valve between cold-producing medium direct expansion formula aerial cooler and the condenser.
Compare with traditional air-conditioning unit and similar Evaporative Cooling Air Conditioning unit, the utility model air-conditioning unit has following characteristics:
1) adopt evaporative cooling to combine, the air-conditioning needs of humidity area and even high humility Area during Summer in can satisfying with mechanical refrigeration.
2) indirect coil pipe is organically combined with direct evaporative cooler, provide cold water for indirect coil pipe, further reduce the temperature of primary air simultaneously with direct evaporative cooler.
3) between primary air (outdoor air adds an amount of building return air) and auxiliary air a part of intermediate air is set, this strand air-flow is recycled water cooling, and the water that causes to fall and break conversely through the direct evaporative cooler filler time is further lowered the temperature.
4) to send the temperature of air lower than similar cooler wind pushing temperature for Xia Mian pressure fan, so institute's required airflow is littler, saves fan energy consumption.
5) compacter than similar cooler construction, can save and take up an area of the space or alleviate the roof load.
Description of drawings
Fig. 1 is the structural representation of the utility model combined air conditioner unit.
Among Fig. 1,1. indirect coil pipe, 2. direct evaporative cooler, 3. cold-producing medium direct expansion formula aerial cooler, 4. compressor, 5. condenser, 6. expansion valve, 7. pressure fan, 8. exhaust blower, 9. water collector, 10. water pump, 11. water fenders.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
As shown in drawings, combined air conditioner unit of the present utility model is made up of indirect coil pipe 1, direct evaporative cooler 2 and 3 three grades of units of cold-producing medium direct expansion formula aerial cooler.
Specifically comprise indirect coil pipe 1 and direct evaporative cooler 2, behind direct evaporative cooler 2, also comprise compressor 4, cold-producing medium direct expansion formula aerial cooler 3 and the pressure fan 7 that sets gradually by air supply direction; Behind direct evaporative cooler 2, also comprise condenser 5, water fender 11 and the exhaust blower 8 that sets gradually by the air draft direction, between cold-producing medium direct expansion formula aerial cooler 3 and the condenser 5 expansion valve 6 is set, constitutes the closed-loop path by pipeline between condenser (5), expansion valve 6, cold-producing medium direct expansion formula aerial cooler 3 and the compressor 4.
Combined air conditioner unit of the present utility model is to the process of air-treatment: the outdoor auxiliary air that is sucked by top exhaust blower 8 carries out precooling to the recirculated water in the indirect coil pipe 1, recirculated water cools off another strand outdoor air (intermediate air) simultaneously, and the water that this strand air-flow causes to fall and break when the direct evaporative cooler 2 is conversely further lowered the temperature.The humid air that produces is discharged from top exhaust blower 8.At last, primary air just outdoor air adds an amount of building return air, is at first cooled off indirectly by the indirect minimum part of coil pipe 1 temperature, carries out final direct evaporative cooling through the minimum position of direct evaporative cooler 2 temperature then.The temperature that following pressure fan 7 is sent air is lower than similar devaporizer wind pushing temperature, so institute's required airflow is littler, saves fan energy consumption.Three grades of compact simultaneously units (coil pipe 1, direct evaporative cooler 2 and cold-producing medium direct expansion formula aerial cooler 3 indirectly) can be saved indoor occupation of land space or alleviate the roof load.
