Description

Direct and indirect dew point evaporation-cooled device
Technical field
A kind of operation of air conditioning systems of the utility model, especially a kind of direct and indirect dew point evaporation-cooled device.
Background technology
At present, the optimization of indirect evaporating-cooling trends towards dew point indirect evaporative cooling, and also immature to the research of this cooler both at home and abroad, majority rests on theoretical research.
Evaporation cooling technique utilizes evaporation of water absorption refrigeration.Without under thermal source condition, hot and humid area process between water and air is that sensible heat transfer feeds water by air, the temperature of air is declined, water capacity increases, the steam entering air takes back some latent heats of vaporization, water temperature reaches the wet-bulb temperature of air gradually, can using the air after cooling as blowing to reduce room temperature, and this process air method is called evaporative cooling.
The utility model adopts directly-dew point evaporative cooling indirectly, and it is the type of cooling of a kind of environment-friendly high-efficiency and economy.There is lower cooling device cost; Significantly reduce power consumption; Reduce the discharge capacity of greenhouse gases and CFC.
Summary of the invention
The purpose of this utility model is just to provide a kind of direct and indirect dew point evaporation-cooled device, this device does not use compressor, direct and indirect evaporating-cooling passage combines, and air and water is carried out direct and indirect hot and humid area, makes below air or water cooling to wet-bulb temperature until reach the Novel thermodynamic cycle device of dew-point temperature.
For achieving the above object, the concrete technical scheme that the utility model is taked is as follows:
A kind of direct and indirect dew point evaporation-cooled device, comprises pressure fan, evaporative cooling dry passage, wet channel, water-locator, air-introduced machine, is provided with film, is provided with aperture in film, be provided with water-locator in described wet channel between described evaporative cooling dry passage and wet channel.
Described water-locator is made up of main, arm and water distributing pore, and described arm is provided with water distributing pore, and arm connects main.Described pressure fan is arranged on evaporative cooling dry passage air inlet, and pressure fan is centrifugal fan.Described air-introduced machine is arranged on wet channel air outlet, and air-introduced machine is centrifugal fan.Described film is the water distribution uniformity material of good hydrophilic property.
Feature of the present utility model is also:
(1) to adopt directly and mode that indirect evaporating-cooling passage combines, make the air themperature after process close to dew-point temperature.
(2) adopt film in wet channel, being uniformly distributed of water can be realized, air and water are fully contacted and carries out hot and humid area, the transpiration-cooled efficiency of dew point can be improved.
(3) adopt 100% all-fresh air to run, air quality is high.And not using compressor, energy consumption is low.
(4) air obtained is low temperature dry air, and the warm and humid independent air-conditioning system controlled can be coordinated to use.
Accompanying drawing explanation
Fig. 1 is the structural representation of direct and indirect dew point evaporation-cooled device;
Fig. 2 is the layout schematic diagram of water distributing pore in wet channel.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
As Fig. 1, shown in 2, direct and indirect dew point evaporation-cooled device of the present utility model, comprises pressure fan 1, evaporative cooling dry passage 2, wet channel 3, film 4, water-locator 5, aperture 6, air-introduced machine 7 and shell 8.
Be provided with film 4 between evaporative cooling dry passage 2 and wet channel 3, in film 4, be provided with aperture 6, in wet channel 3, be provided with water-locator 5.
As shown in Figure 2, water-locator is made up of main 9, arm 10 and water distributing pore 11, and arm 10 is provided with water distributing pore 11, and arm 10 connects main 9.
Pressure fan 1 is arranged on evaporative cooling dry passage 2 air inlet, and pressure fan 1 is centrifugal fan.Air-introduced machine 7 is arranged on wet channel 3 air outlet, and air-introduced machine 7 is centrifugal fan.Described film 4 is the water distribution uniformity material of good hydrophilic property.
In the utility model, by pressure fan 1, new for outdoor wind is sent into dry passage 2, portion of air enters wet channel 3 by aperture 6, carries out hot and humid area with the water in film 4, and temperature reduces, thus indirectly cools the air in dry passage.And cooled air some enter wet channel 3 and proceed Indirect Evaporative Cooling Process, portion of air directly discharges.Through multi-stage indirect evaporative cooling, finally obtain the air close to dew-point temperature lower than wet-bulb temperature.
