The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the present invention is elaborated.
Dew point of the present invention is indirect, direct evaporative cooler modularization Evaporative Cooling Air Conditioning; Its structure is as shown in Figure 1, includes the Evaporative Cooling Air Conditioning housing, is respectively arranged with air inlet 1 and air outlet 9 on the relative two side of Evaporative Cooling Air Conditioning housing; The Evaporative Cooling Air Conditioning case top is provided with exhaust outlet 10; Be disposed with blower fan 3, dew point indirect evaporative cooler 4 and direct evaporative cooler 6 by the air intake direction in the Evaporative Cooling Air Conditioning housing, be provided with roughing efficiency air filter 2 between air inlet 1 and the blower fan 3, the top of dew point indirect evaporative cooler 4 and direct evaporative cooler 6 is provided with water-locator 11; The below of dew point indirect evaporative cooler 4 and direct evaporative cooler 6 is provided with cistern 5; Be provided with water compensating valve 8 in the cistern 5, cistern 5 is connected with water-locator 11 through feed pipe, and feed pipe is provided with water circulating pump 7.
Blower fan 3 can adopt forced blower fan; Water-locator 11 adopts the spray arm or adopts nozzle.
Dew point indirect evaporative cooler 4 can adopt the dew point evaporative cooler of cross-current design or use the dew point indirect evaporative cooler of counter-flow designs, and material is elected papery, aluminium foil, metal or PVC as.
The filler of direct evaporative cooler 6 adopts papery, metal, porous ceramics or PVC.
The present invention is the vaporizing and cooling air conditioning device that adopts modularization to be provided with dew point indirect evaporative cooler and direct evaporative cooler, and design has been adopted in the ideal case, can air intake be cooled to its dew point indirect evaporative cooler below wet-bulb temperature.Because wind pushing temperature is lower, so the appearance and size of entire equipment can reduce accordingly.This unit adopts modularized design, can start different devaporizers according to different air quantity, so just can in engineering reality, use flexibly.Can adopt outdoor new wind as air intake, this air-conditioning places when indoor, can connect fresh wind tube, and outdoor new wind is introduced unit; Also can directly adopt indoor return air as air intake, cooperate exhaust blower to use.
This Evaporative Cooling Air Conditioning can be selected to open dew point indirect evaporative cooler 4 or direct evaporative cooler 6, to satisfy the requirement of actual air conditioning area to humiture according to the needs of actual engineering flexibly.When air-conditioning is only opened dew point indirect evaporative cooler 4; Primary air does not directly contact with water; So the processing procedure of primary air is etc. but clammy; The humidity of direct evaporative cooler 6 air-supplies is not compared with air intake and is changed relatively, so the scope of using is more extensive, can in the engineering that humidity is had requirement, use.
The course of work of Evaporative Cooling Air Conditioning of the present invention:
Select flexibly according to actual needs to open dew point indirect evaporative cooler 4 or direct evaporative cooler 6, to satisfy of the requirement of actual air conditioning area to humiture.
After the air intake of this Evaporative Cooling Air Conditioning got into Evaporative Cooling Air Conditioning through air-conditioning air inlet 1, a part of air-conditioning got into the wet channel in the dew point indirect evaporative cooler 4, and this part air is called as auxiliary air (control air).The air that another part gets in the dry passage is called as primary air (output air).Auxiliary air contacts with water in the wet channel of dew point indirect evaporative cooler 4 fully, and water evaporative cooling in the wet channel is carried out heat exchange with air in the dry passage, takes away the heat of primary air in the dry passage, finally discharges through exhaust outlet 10; Primary air is through the wall between dry passage and the wet channel, and with the auxiliary air in the heat transferred wet channel, this process such as is at clammy but process.Primary air comes out from dew point indirect evaporative cooler 4, gets in the direct evaporative cooler 6, and in direct evaporative cooler 6, primary air after the adiabatic humidiflcation, is sent into air conditioning area through air outlet 9 in direct evaporative cooler 6.
Water is promoted to the water-locator 11 of dew point indirect evaporative cooler 4 and direct evaporative cooler 6 tops through water circulating pump 7; Evenly spray to dew point indirect evaporative cooler 4 and direct evaporative cooler 6 through water-locator 11; Redundant moisture is got back to the cistern 5 that is arranged in dew point indirect evaporative cooler 4 and direct evaporative cooler 6 belows, so circulation.
Because its special design, its occupation mode is also flexible and changeable, can be according to the needs setting of concrete engineering.This modularization Evaporative Cooling Air Conditioning, each all is certain air quantity, and can parallel connection use, and selects the mode of using according to actual needs flexibly.When the requirement of engineering transformation is perhaps extended, can install or remove this air-conditioning flexibly according to the variation of air conditioner load.The field of employment of this equipment is extensive, can be used as domestic air conditioning, also can be used for electronic information machine room and industrial site.
