The present invention combines the dew point indirect evaporative cooling central air-conditioning system of gas heater, its course of work difference It is as follows:
(1) the wind system course of work is specific as follows:
Outdoor air is entered in machine unit shell under the swabbing action of exhaust blower 10 by air inlet 1, is filtered by fresh air single The air of cleaning is formed after first 2 (air cleaners) filtering;
Clean air is divided into two parts:A part of clean air cools down as control air into dew point indirect evaporative In the air dry passage of core body 3 by etc. it is clammy but, enter wet sky by the aperture of the top of dew point indirect evaporative cooling core body 3 afterwards Between, it cools down the air of dry passage as Secondary Air by moisture evaporation, and hereafter it is introduced into direct evaporative cooler again, Preliminary direct evaporating-cooling is carried out at direct evaporating-cooling filler 6;The clean air of another part is through dew point indirect evaporative It is directly entered after the air dry passage of cooling core body 3 is cooled in direct evaporative cooler, the quilt at direct evaporating-cooling filler 6 Cooling;
Air after direct evaporating-cooling separates through water fender 11 to water droplet, finally in the suction of exhaust blower 10 Under effect, sent out through exhaust outlet 9.
2) the water system course of work is specific as follows:
First, it is cold to be delivered to dew point indirect evaporative in the presence of water circulating pump 5 through water pipe for the water in cyclic water tank 4 But use in water-locator 13, and come out by dew point indirect evaporative cooling with water-locator 13 by Water spray is circulated, spray the circulation got off Water falls carries out hot and humid area in the wet channel of dew point indirect evaporative cooling core body 3 with control air, after hot and humid area terminates Recirculated water is fallen under gravity into cyclic water tank 4, is moved in circles;
Then, the water after the load of user end 14 is absorbed in direct evaporative cooler and is passed through direct evaporating-cooling water-locator In 12, by the water that direct evaporating-cooling water-locator 12 sprays in direct evaporating-cooling filler 6 successively and two strands of air Hot and humid area is carried out, is fallen back under gravity in cold water storage cistern 7 after hot and humid area terminates, the high temperature cold water in cold water storage cistern 7 User end 14 is supplied by high temperature cold water feed pipe 17, moved in circles.
In summer, dew point indirect evaporative of the invention cooling central air-conditioning system, the cold water that will be produced by water pipe The user end 14 (fan coil) of premises is sent into, after the heat that cold water absorbs premises, temperature rise, then flow into dew point In indirect evaporating-cooling air-conditioner set, heat is shed in dew point indirect evaporative cooling air conditioning group;Steamed indirectly by dew point The control air after the dew point indirect evaporative cooler but in air-conditioner set that feels cold is introduced in direct evaporation further through exhaust blower The top of cooler, the air of the lower flow of direct evaporative cooler are the output wind that dew point indirect evaporative cooler comes out, It can so be cooled down twice next moisture is flowed through from user end 14;Exhaust blower in dew point indirect evaporative cooling air conditioning group 10 use suction type fan, and this make it that the air into machine unit shell is evenly stablized, and evaporation cooling is preferably played its work With.
In the winter time, the dew point indirect evaporative cooling in dew point indirect evaporative of the invention cooling central air-conditioning system is empty Adjust unit to close, open the valve on the 4th water pipe G4, the outlet of gas heater 15 is connected by the 4th water pipe G4, the 3rd water pipe G3 It is logical, it is connected with the water lines in user end 14 (fan coil), after the water in water lines is heated by gas heater 15, Temperature raises, and flows to each user end 14 (fan coil), enters in the user end 14 (fan coil) of premises with air After row heat exchange, water temperature reduces, and flow back into gas heater 15, the water after cooling is added again in gas heater 15 Heat, move in circles.
The dew point indirect evaporative cooling central air-conditioning system combination gas heater of the present invention uses, feasible system Two season of summer in winter free switching, in use with energy consumption is low, good refrigeration effect and will not generation environment pollution the characteristics of.
