The specific embodiment
For the ease of it will be appreciated by those skilled in the art that the present invention's design is explained in further detail below in conjunction with accompanying drawing and specific embodiment.
A kind of non-refrigerant air-conditioning unit shown in Fig. 1～4 comprises indoor and the outside that is connected the right side, indoor.Described non-refrigerant air-conditioning unit is realized multistage cool-down dehumidification by the mode of surface cooler and blower fan, the curtain combination of wetting.It is included as surface cooler and the outside 21 of cooling water is provided and the air in the inlet chamber is carried out the indoor 20 of multistep treatment, and indoor 20 and outside 21 connect and compose the non-refrigerant air-conditioning of monoblock type unit.
On the sidewall of outside cooling blower is installed, described cooling blower is installed in right side wall middle part, outside, and outside antetheca, rear wall are provided with air inlet, is respectively arranged with the first wet curtain component near outside antetheca air inlet, rear wall air inlet.The first wet curtain component is selected the big wet curtain of disengagement area, for example 7090 wet curtains.Present embodiment is symmetrical arranged two wet curtains that disengagement area is big in the outside, high-power cooling blower is arranged on the centre position of outside front and rear wall air inlet, has improved evaporation efficiency greatly.
The first water supply assembly 3 is installed at 21 middle parts in the outside, the first wet curtain component 1 is connected with surface cooler 4 in being arranged on the indoor by the first water supply assembly, described cooling blower 2, the first wet curtain component 1, the first water supply assembly 3, surface cooler 4 constitute evaporative cooling system, and this evaporative cooling system provides recirculated cooling water for surface cooler.
The first water supply assembly 3 comprises the water pond that is positioned at 21 bottoms, outside, is connected the ball float water compensating valve on the water pond, the water pump that is connected with the water pond pipeline, with the pipeline that is connected the surface cooler and the first wet curtain component, water pond is by past its interior moisturizing of ball float water compensating valve, the water pump inlet ductwork is connected to water pond, exit of pump is connected to the surface cooler import by pipeline, the surface cooler outlet is connected to the first wet curtain component by pipeline again, and the water that flows through the first wet curtain component flows directly into water pond.
The non-refrigerant air-conditioning of the present invention working principle of said set is as follows: the air of open-air seasoning (low enthalpy) is through after the conveying of cooling blower 2, by the corresponding first wet curtain component 1 that is provided with of flowing through of the air inlet on 21 front and back walls of outside; In suction place of cooling blower, the air relative pressure of the first wet curtain component position is a negative pressure; The water of damp and hot (high enthalpy) that the surface cooler outlet is flowed out drenches down through the first wet curtain component.When water droplet contacts with air, on the one hand because the direct heat transfer of air and water, on the other hand owing to have pressure differential between air and the water vapour, under the effect of pressure, produce Evaporation Phenomenon, take away evaporation of water latent heat, thereby reduction water temperature, water at low temperature flow into water pond and pass through water pump supply schedule cooler 4 again, surface cooler 4 again with inlet chamber inboard 20 in air carry out heat exchange.
The evaporative cooling system that is provided with in the outside 21 is used for providing cooling water to the surface cooler 4 that is installed in the indoor, surface cooler 4 be used for inlet chamber in air to carry out heat exchange be air cooling-down.During work, the high-temperature water that the water pump in the outside 21 is sent surface cooler 4 outlets is after the first wet curtain component cooling, flow in the water pond, the surface cooler of supply chamber inboard, water at low temperature in surface cooler with the air heat exchange, absorb airborne heat, water temperature raises, the high-temperature water that the surface cooler outlet is flowed out sprays on the first wet curtain component again, flows through the water of the first wet curtain component 1, flows directly into water pond after cooling, water at low temperature in the water pond is the supply schedule cooler once more, successively periodic duty.
The present invention can not produce obvious influence by the moisturizing in the water pond of ball float water compensating valve to whole cool-down dehumidification process, because utilization of the present invention is the latent heat of water, the sensible heat proportion is very little.
The non-refrigerant air-conditioning of the present invention unit is sent into indoor new wind processing procedure: the air of open-air seasoning is sent to surface cooler 4 by indoor blower fan 5, carry out heat exchange with the water at low temperature that flows in the surface cooler 4, because for surface cooler provides the vapo(u)rization system disengagement area of cooling water big, the cooling water water temperature is lower in the surface cooler, after surface cooler and the air heat exchange, the temperature of air can be reduced near dew-point temperature.After the surface cooler heat exchange, the enthalpy of air reduces, water capacity increases (as the a-b processing procedure line in the accompanying drawing 5,6) relatively, the air of the low enthalpy of handling through surface cooler of the low temperature second wet curtain component 6 that continues again to flow through, the air of the low enthalpy of second wet 6 pairs of low temperature of curtain component carries out the constant enthalpy insulation, air is handled state point c by the state point b in the accompanying drawing 5,6, and the temperature of air slightly rises, and water capacity reduces relatively.The globule is brought into indoor for the air that prevents to flow through the indoor second wet curtain component, between indoor second wet curtain component and indoor air outlet, be provided with water fender 8.Thus, after outdoor new wind is delivered to surface cooler cooling, the second wet curtain component dehumidifying by the indoor blower fan, through water fender in the air outlet of indoor set inlet chamber.
The above embodiment has only expressed embodiments of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to claim of the present invention.Should be noted that; for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make certain adjustments and improvements; as launch selection variation of modulation treatment circuit and receiving processing circuit etc., these all belong to protection scope of the present invention.
