The operation principle and the course of work of the floride-free ventilation type energy-saving air conditioner of the utility model are as follows:
After air conditioner starts, gas mixing dryer (4) sucks the cold air and the additional air of circulation step-down case (2), behind combination drying, supply with compressor (5), gas reaches the pressure of 0.7-1.0Mpa after compression, water after filtration deoils, enter heat exchanger (7), the cold air source of heat exchanger (7) is from circulation step-down case (2), and heat exchange waste gas is sent into the cabinet back and discharged outdoor by sending out the hot fan (66).Compressed Gas drops to about 25 ℃ from 32 ℃ through cooling, and this gas of 25 ℃ enters differential pressure refrigeration device (8), and gas is through swell refrigeration, and cold airflow enters distributor (7); Because cold airflow pressure is 0.12-0.15MPa only, can reach 0.3MPa through distributor (7) supercharging, enter the supercharging output once more of distributor (7), jet blower (56) then; Mix simultaneously with the big air quantity gas of cooling of circulation cooling system be blown into through front windshield indoor.
The course of work of circulation cooling air distribution system is as follows:
After motor (37) starts, driving wind wheel (38) runs up, make depression circulating box (2) form negative pressure, thereby ambient atmos is sucked drier (42), and impurity, dust in the gas are absorbed, after filtration after the dehydration, gas enters primary heat exchange pipe (41) under water, the rising of air and steam enters gas distribution chamber (44) after heat exchange, and the peptizaiton through air dividing plate (43) evenly rises again, and contacts with heat exchange curtain (45) at once.When gas enters primary heat exchange pipe (41) when contacting with water at low temperature, in the process that institute's heat content is absorbed by water at low temperature, be the transmission of having carried out heat with the sensible heat form, the form of water does not change, and gas temperature reduces; Then, when gas process distribution plate (43) and heat exchange curtain (45), the heat in the gas continues to be retained in the active water boundary layer, at this moment by the absorption of the boundary layer of water, the contained sensible heat of gas is converted into the heat of vaporization of water very soon, and water is converted into gaseous state and is temperature-resistant; This moment is lower because of heat exchange curtain (15) temperature, makes vaporize water (containing latent heat) change liquid state into from gaseous state again, and water is temperature-resistant in this condenses phase transition process.
At this moment, immersible pump (48) is delivered to shower (46) with the water at low temperature of bottom in the case by lifting pipe (47), under the pressure of water, sparge pipe (48) is sprayed onto the water atomisation on the heat exchange curtain (45), the shower water of this moment and contain the condensate water combination of latent heat is in heat exchange curtain (45) is dashed water below taking back, owing to the behavior of boundary layer of water, this latent heat floats to the boundary layer of water again, and the temperature of water has only very little variation.The characteristics of above-mentioned heat exchanging process be with water as heat transmission medium, between gaseous state and liquid state, follow to change and make phase-state change, transmit heat with the latent heat form, thereby temperature-resistant, so can freeze to air effectively;
Simultaneously, semiconductor refrigerating element (32) is in the refrigeration work state, and interior surface temperature is-35 ℃--and 30 ℃, when immersible pump (47) promoted water through lifting pipe (48), water was cooled to 10-5 ℃, is sprayed by shower (46) then
At last, under the effect of wind wheel (38), reached at aforementioned jet and carry down, and mix, send into indoor by vent window before the case (60) with Gas Jet by the gas of moistening and lowering temperature.
Above described be cold logical working condition in summer, below the explanation winter HVAC working condition:
When wind wheel (38) when running up, the quartz ampoule (51) of heater is opened, and opened semiconductor refrigerating element (32) change-over switch, make the interior surface temperature of semiconductor refrigerating element (32) be controlled at 50-60 ℃, the outside is controlled at 0-10 ℃; This semiconductor element (32) makes the water (4-10 ℃) through lifting pipe (47) be warmed up to 25-30 ℃ significantly, follows shower (47) ejection of changing in the case (35) by negative pressure then, is sprayed onto on the heat exchange curtain (45); After cold air passes through air dividing plate (43), during through heat exchange curtain (45), absorbed the sensible heat in the water, temperature raises, and by the water humidification; Simultaneously, the very fast hot water with spray of moisture content that contains sensible heat in the gas combines and gets back in the water, and in this process, the phase of water does not change, so heat is to pass to gas with the sensible heat state to make gas heating.
Because this moment, gas heating was high not enough, so gas further heats by heater again under the effect of wind wheel (38); And the water capacity of gas is reduced.So reciprocally circulation makes gas be purified and heats up, thereby plays the effect of warm color tone.The used motor of the utility model (37) can be the alternating current generator of 40W, 2500r/min, and rotor diameter is 120mm, and the semiconductor refrigerating element is the tube element of internal diameter 4-8mm, long 120-200mm, operating voltage 12V, 5A; The quartz ampoule of heater employing＜600W.Can cause the temperature difference in summer, and institute's cold wind air quantity that send is very big, can reach 250-350Kg/h than low 5-8 ℃ of environment temperature.
On the basis of above-mentioned basic principle and structure, the utility model also can have multiple variation, as shown in figure 11, promptly be another embodiment of the present utility model, this cooling and heating machine (34-2) (38-2) is made of with two negative pressure torus (38-1) a motor room (33), two wind pushing cavities (34-1); A motor (37) drives two typhoons wheels (35-1) (35-2), (38-2) communicates with two negative pressure torus (38-1), thereby has strengthened the air conditioning amount.
