Have following problem for the hypogee is provided with the ground cooling tower: one when ground is the commercial location of prosperity, is difficult to find the position of placing cooling tower; Its two, cooling tower operation the time have fine liquid particles to around fly away " water wafts " phenomenon, may contain germs such as Legionella in this water droplet, cause environmental pollution, the crowd is dense in the city that the location is unallowable for this; Its three, in cooling tower when operation,, because reasons such as blower fan running, trickle can produce bigger noise, this has caused the obvious noise pollution to urban environment.Though the utility model is primarily aimed at the hypogee, also there is similar problem in the present in fact and matching used cooling tower of surface structures when being provided with,
Summary of the invention:
The purpose of this utility model is in order to solve the hypogee problem that the ground cooling tower exists to be set, for the hypogee provides a kind of reasonable in design, operating cost is low and do not take the underground cooling tower of floor area.
Underground cooling tower of the present utility model is mainly by underground tank, water inlet pipe, nozzle, filler, filler support, deep bead, outlet pipe, filling pipe, ball-cock assembly, wind inlet channel, wind output channel and blower fan are formed, the correlation of each part is: water inlet pipe is positioned at the top of underground tank, nozzle links to each other with water inlet pipe, filler is fixed by filler support and is positioned at the nozzle bottom, deep bead is positioned at the top of the windward side and the leeward side of filler, outlet pipe is positioned at the underground tank bottom, filling pipe is positioned at underground tank top and is connected with ball-cock assembly, one end of wind inlet channel is connected with underground tank at the windward side of filler, one end of wind output channel is connected with underground tank at the leeward side of filler, and blower fan is positioned on wind inlet channel or the wind output channel.Be placed with phase-change material in the described underground water pool inner water.When described wind output channel was airduct, airduct was selected thermal insulation wind pipe for use.
Underground tank is one and is located in the hypogee and pond that volume is bigger.The material of filler is paper or plastics etc., is cellular, can use general ground cooling tower or the used filler of wet film evaporative humidifier.Ball-cock assembly keeps the water surface of underground tank to be stabilized in position a little more than the filler lower edge, and the purpose of doing like this is to avoid forming the slit between the filler lower edge and the water surface and air was leaked.The windward side of filler refers to that air flows into a side of filler, and leeward side refers to that air flows out a side of filler.Deep bead is positioned at the top of filler windward side and leeward side, its objective is that blocks air leaked between the end face of filler upper limb and underground tank.Remove outside the end that is connected with underground tank, the other end of wind inlet channel and wind output channel all leads to ground, can blast cap be set respectively at floor outlet.Outlet pipe generally connects water pump, then connects the thermals source such as condenser of refrigeration machine in the hypogee, and the back connects water inlet pipe again, thereby forms a circulation waterway.

The preparation method of thermal insulation wind pipe can be to install heat-insulation layer additional on the airduct surface, installs heat-insulation layer additional as the surface at the iron sheet airduct: also can be to install heat-insulation layer in the middle of the airduct material layer additional, install heat-insulation layer in the middle of the airduct tube wall as glass fibre reinforced plastic blast pipe additional.
The method of operation of hypogee can be divided into two kinds of continuous operation and intermittent duties.Operation refers to that the hypogee all is in user mode round the clock continuously, and the thermals source such as condenser of refrigeration machine continue to have caloric requirement to distribute in the hypogee.Intermittent duty refers to that the hypogee moves night daytime and stop using, and the thermals source such as condenser of refrigeration machine have caloric requirement to distribute daytime the hypogee in, and night, these thermals source were inactive, so there is not heat to distribute.
When underground building was moved continuously, ruuning situation of the present utility model was: open blower fan, air enters underground tank by blast cap, wind inlet channel from ground, then is horizontally through filler, is discharged to ground by wind output channel, blast cap.Water in the underground tank is driven the thermals source such as condenser that flow to refrigeration machine in the hypogee from outlet pipe by water pump, being heated the back in thermals source such as condenser flows back to from water inlet pipe, by the nozzles spray that links to each other with water inlet pipe to filler, through behind the filler, fall in the pond, bottom, water in the underground tank drives the thermals source such as condenser that flow to refrigeration machine in the hypogee from outlet pipe by water pump again, and so forth circulation.On filler, the higher water and air of temperature of nozzle ejection carries out the wet exchange of heat, thereby water evaporates reduces water temperature, and the moisture content of evaporation is brought to ground with air draft, thereby reaches the purpose that underground waste heat is dispersed into ground.Along with the evaporation of moisture content, the water level in the pond will descend, and the general who has surrendered opens ball-cock assembly under the water level, and by filling pipe moisturizing in underground tank, the water surface of maintenance underground tank is stabilized in the position a little more than the filler lower edge.Filling pipe can be connected with the domestic water supplying system of hypogee.The design parameter of ground cooling tower is generally 37 ℃ of inflow temperatures, through 32 ℃ of cooling tower cooling back leaving water temperatures, the desirable and essentially identical water-in and water-out design parameter of ground cooling tower of the utility model.Like this, the water temperature when the utility model moves continuously in the underground tank just all is higher than the phase transition temperature of phase-change material, so when moving continuously, phase-change material does not undergo phase transition substantially.
When underground building intermittent duty, ruuning situation of the present utility model is as follows:
At night, owing to stop using in the hypogee, so thermals source such as condenser will be stopped using, promptly water is by temperature-resistant before and after the thermals source such as condenser, and open blower fan and water pump this moment, and it is equally mobile to allow the sky G﹠W move continuously as described above.Because thermals source such as condenser are distribute heat no longer, so the water temperature in the underground tank will reduce, when dropping to the phase transition temperature of phase-change material, phase-change material will be in water release heat, become solid-state gradually by liquid state, close blower fan, water pump when water temperature no longer reduces in the underground tank, stop the operation of this underground cooling tower.The next morning, the hypogee came into operation again, in a period of time after thermals source such as condenser are enabled, do not open blower fan, only opening water pump makes the water in the underground tank circulate by thermals source such as condensers, since the water in the underground tank evening before that day temperature fallen lowlyer, so in a period of time, only just can satisfy the cooling requirement of thermals source such as condenser by the rising of water temperature in the underground tank.When water temperature is elevated to the phase transition temperature of phase-change material, phase-change material will be changed to liquid state by solid-state, absorb heat from water; In this process, water temperature does not raise or heats up slowly.When phase-change material by solid-state change liquid state into fully after, water temperature continue to raise.Behind the design inflow temperature of water temperature above thermals source such as condensers, open blower fan, the overhead G﹠W of filler carries out the wet exchange of heat, and heat takes ground to by air draft, keeps this running status to finish up to daytime, and the hypogee is inactive.Then again by aforementioned method of operation operation at night, so move in circles at daytime, night night.Do like this, actual is exactly to utilize water and phase change material cool storage in the underground tank at night, for using daytime.So operation can be saved operating cost, because the time-of-use tariffs difference, night, electricity price was cheap, and night, outside air temperature was lower than the daytime, and can lower the water temperature in the underground tank in the shorter time night.
When wind output channel was airduct, airduct was that the purpose of thermal insulation wind pipe is to prevent that all very high air draft of humiture from condensing in a large number because of tube wall temperature is lower when airduct flows, and accumulates excessive water in airduct.Also should take measures on the wind output channel water that condenses along the air channel is discharged smoothly.
Advantage of the present utility model is: one, and underground cooling tower is located at underground, can reach the radiating effect same with the ground cooling tower, but need not look for placement location on ground; Its two because the wind output channel of underground cooling tower is longer, the fine liquid particles major part that contains in the air draft drops in the wind output channel, the water droplet that finally is discharged in the ground air will significantly reduce, and promptly eliminate " water wafts " phenomenon substantially; Its three, the blower fan of underground cooling tower is located at underground, trickle is in underground tank, it will be very little that these sound pass to ground influence to external world, obviously reduce the noise pollution to ground environment.Generally speaking, the utility model can solve present hypogee preferably the problem that the ground cooling tower exists is set, and has reasonable in design, operating cost is low and does not take advantage such as floor area.The utility model is best suited for the hypogee, but also applicable to surface structures.
