If evaporation cooling technique is combined with traditional mechanical refrigeration, be implemented in high temperature and utilize evaporation cooling technique that new wind is carried out precooling hot season, 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.

Summary of the invention

The purpose of this utility model provides a kind of evaporative cooling and mechanical refrigeration combined air conditioner unit, utilizes evaporation cooling technique that new wind is carried out precooling hot season at high temperature, cools off through mechanical refrigeration again; And a large amount of transition seasons use evaporative cooling to reach the purpose of regulating air separately.

The technical scheme that the utility model adopted is, evaporative cooling and mechanical refrigeration combined air conditioner unit, comprise the new wind section of the unit that sets gradually, machine set filter, tube type indirect evaporative cooler, unit air return section, mechanical refrigeration surface cooler, direct evaporative cooler and unit blower fan by the air intake direction, the mechanical refrigeration surface cooler is connected with the outlet of mechanical refrigeration evaporimeter and evaporative condenser respectively by pipeline.

The mechanical refrigeration surface cooler is provided with can regulate the bypass air-valve.

Compare with the mechanical refrigeration handpiece Water Chilling Units with traditional Evaporative Cooling Air Conditioning unit, air-conditioning unit of the present utility model has following characteristics:

1) adopts the precooling of one-level indirect evaporation surface cooler to combine, form three grades of air-conditioning units, and the condenser of mechanical refrigeration system is selected evaporative condenser for use with mechanical refrigeration surface cooler, direct evaporative cooler." dual-use ", on the one hand when opening mechanical refrigeration the hottest month of summer as evaporative condenser; Cold-producing medium is played the condensation thermolysis.On the other hand, in the transition season that mechanical refrigerator is not opened,, be combined into cooling tower cooling type indirect evaporation cooler, carry out " free cold supply " with surface cooler as used for cooling tower.In order to improve the heat exchange efficiency of evaporative condenser, at the air intake place evaporative cooling filler is set, not only air had been carried out precooling but also played filtration, dust, dirt in the air of inlet are filtered, it is comparatively clean to have guaranteed to lead in the tank of bottom surface cooler water quality.

2) mechanical refrigeration surface cooler " device is dual-purpose ", the low-temperature cold water that hot season in summer, logical mechanical refrigeration was produced, transition season mechanical refrigeration unit is not opened, the high temperature cold water that logical cooling tower is produced.

3) the air-conditioning air-supply (temperature drop reaches 15~20 ℃) that can provide three grades of Evaporative Cooling Air Conditioning air-supplies or the cooling of one-level indirect evaporation to combine simultaneously with mechanical refrigeration, and can produce 15~20 ℃ of chilled waters.

Description of drawings

Accompanying drawing is the structural representation of the utility model evaporative cooling and mechanical refrigeration combined air conditioner unit.

Among the figure, the 1. new wind section of unit, 2. machine set filter, 3. tube type indirect evaporative cooler, 4. unit air return section, 5. mechanical refrigeration surface cooler, 6. direct evaporative cooler, 7. unit blower fan, 8. mechanical refrigeration evaporimeter, 9. evaporative condenser 10. can be regulated the bypass air-valve.

The specific embodiment

Below in conjunction with the drawings and specific embodiments the utility model is elaborated.

Combined air conditioner unit of the present utility model is a core with one-level indirect evaporation cooler, mechanical refrigeration surface cooler, tube type indirect evaporative cooler and small-sized machine refrigeration system organically are combined with each other three grades of air-conditioning units that the precooling of tubular indirect evaporative surface cooler is combined with mechanical refrigeration surface cooler, direct evaporative cooler and forms.Wherein the condenser of mechanical refrigeration system is selected evaporative condenser for use.As shown in drawings, comprise the new wind section 1 of the unit that sets gradually, machine set filter 2, tube type indirect evaporative cooler 3, unit air return section 4, mechanical refrigeration surface cooler 5, direct evaporative cooler 6 and unit blower fan 7 by the air intake direction.

Mechanical refrigeration surface cooler 5 is connected with the import and export of mechanical refrigeration evaporimeter 8 with evaporative condenser 9 respectively by pipeline A, B and D, E through the conversion of three-way valve P1, P2; When mechanical refrigeration surface cooler 5 is connected with mechanical refrigeration evaporimeter 8 by pipeline A, B, regulate three-way valve P3, P4 and close D, E pipeline section, make the spray recirculated water of evaporative condenser carry out the self-loopa spray by pipeline section C.

First order tube type indirect evaporative cooler in the utility model evaporative cooling and the mechanical refrigeration combined air conditioner unit adopts the recirculated water spray, and used low temperature and high temperature cold water are respectively from mechanical refrigeration handpiece Water Chilling Units and cooling tower in the mechanical refrigeration surface cooler 5.Wherein,, be provided with at surface cooler 5 places and can regulate bypass air-valve 10, under the design conditions, can regulate bypass air-valve 10 and close fully, send into the room fully after treatment after new return air mixes in order to satisfy the not requirement of chummery ventilation state point.When indoor waste heat, surplus wet variation, Electric air valve is regulated aperture automatically, and regulates bypass wind and the mixing ratio of handling wind, makes to mix the requirement that the back air-supply reaches the indoor design condition parameter.Evaporative cooling and mechanical refrigeration combined air conditioner unit provide the air of cooling for building.

The course of work of evaporative cooling and mechanical refrigeration combined air conditioner unit: hot season in summer, outdoor air passed through the new wind section 1 of unit successively, after machine set filter 2 filters, through tube type indirect evaporative cooler 3 coolings, by further cooling off through mechanical refrigeration surface cooler 5 again behind the unit air return section 4; The transition season outdoor air passes through the new wind section 1 of unit successively, after machine set filter 2 filters, through tube type indirect evaporative cooler 3 coolings, continue cooling through surface cooler 5 again, (high temperature cold water of the logical cooling tower preparation of surface cooler this moment) is through third level direct evaporative cooler 6 equal-enthalpy humidifyings, can make outside air temperature reduce about 15~20 ℃, the air after the cooling is sent in the building through unit blower fan 7.

Characteristics of the present utility model are multistage evaporation to be cooled off unit and mechanical refrigeration unit are compound to be one, make full use of the energy-saving effect of evaporative cooling " free cold supply ", according to the variation of outdoor climate and indoor load, provide the air of cooling for building separately or with the mechanical refrigeration Combined Treatment.This equipment " dual-use ", on the one hand when opening mechanical refrigeration the hottest month of summer as evaporative condenser; Cold-producing medium is played the condensation thermolysis.On the other hand, in the transition season that mechanical refrigerator is not opened, played the effect of cooling tower, be combined into cooling tower cooling type indirect evaporation cooler, carried out " free cold supply " with surface cooler.Both reduce the energy consumption of a large amount of mechanical refrigeration systems that adopt in the present engineering, improved compressor output, reduced the discharging of pollutant simultaneously again.
