when the air conditioning unit operates, the fan assembly 3 extracts air in the decompression chambers 1-4 through the heating chamber 2, meanwhile, the return air pipe 8 infuses return air into the condensation chambers 1-1, the fresh air pipe 7 infuses fresh air into the condensation chambers 1-1, and the fresh air and the return air exchange heat spirally in the condensation chambers 1-1.
When the return air and the fresh air are fused in the condensation cabin 1-1, the fresh air with high temperature meets the return air with low temperature or the fresh air with low temperature meets the return air with high temperature, and the fresh return air is condensed to form water mist in the condensation cabin 1-1.
The return air pushes the spiral fan blade 10 to rotate in the condensation cabin 1-1, so that the fresh air and the return air perform spiral heat exchange in the condensation cabin 1-1, meanwhile, the water mist is continuously fused into water drops under the drive of the airflow and absorbs the surrounding impurities, so that the impurities are separated from the fresh air, the fresh air returns to the decompression chamber 1-4 under the influence of the fan component 3 while rotating in the condensation chamber 1-1, and when the fresh air returns through the speed increasing pipe 1-2, because the aperture of the speed increasing pipe 1-2 is shrunk, the speed of the fresh air returning through the speed increasing pipe 1-2 is increased, after the fresh air returning enters the separation cabin 1-3, the fresh return air continues to move in the direction of the decompression chambers 1-4 under the influence of the fan assembly 3, whereas the water droplets with impurities fall under the influence of weight and speed into the bottom of the separation chamber 1-3.
When the air conditioner unit operates, the inlet pipe feeds water into the water storage cabin, the floats 12-9 in the water storage cabin float upwards under the support of water and respectively pull the inner plate 12-3 and the water gauge plate 11-3 through the ropes 12-8 and the branch ropes 12-10, so that the water gauge valve and the airflow valve respectively control the fluid flow of the booster pipe 12 and the water storage cabin, and the booster pipe 12 pumps air into the water storage cabin under the action of an external machine, so that the pressure in the water storage cabin is increased.
When the water level in the water storage tank is high, the pressure of water on the water spray pipe 11-5 is higher than the pressure of water on the water spray pipe 11-5 when the water level is low, and at the same time, the pressurizing pipe 12 infuses a small amount of air into the water storage tank, so that the water at the bottom of the water storage tank is sprayed into the separation tank 1-3 through the water flow valve and the water spray pipe 11-5 under the extrusion of the upper water and the action of air pressure;
when the water level in the water storage cabin is low, the pressure ratio of water to the water spray pipe 11-5 is smaller, the atomization effect of water entering the separation cabin 1-3 through the water spray pipe 11-5 is poor, and a large amount of air is infused into the water storage cabin through the pressurization pipe 12, so that the water enters the separation cabin 1-3 in a water mist state through the water quantity valve and the water spray pipe 11-5 under the action of high pressure.
When the fresh return air flows below the spray pipe 11-5, the impurities are contacted with the water mist and separated from the fresh return air under the driving of the water mist, so that the fresh return air is subjected to secondary filtration.
When the fresh and return air needs to be heated, the fresh and return air enters the friction shell 2-1 through the air inlet through groove and pushes the friction plate 2-3, so that the friction ball 2-2 drives the friction plate 2-3 to rotate in the friction shell 2-1, the heating assembly heats the fresh and return air through the magnetocaloric effect, and the heated fresh and return air enters the fan assembly 3 through the air outlet through groove; when the new meeting wind does not need to be heated, the new return wind enters the fan assembly 3 through the normal temperature channel.
The fan assembly 3 transmits fresh and return air to the cooling cabin 4, the cooling cabin 4 cools the fresh and return air through the cooling pipe, the shunting cabin 5 shunts the cooled air, and the cooled fresh and return air is infused into the air-conditioning room through the shunting pipe 6.
It will be evident to those skilled in the art that the invention is not limited to the details of the foregoing illustrative embodiments, and that the present invention may be embodied in other specific forms without departing from the spirit or essential attributes thereof. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein. Any reference sign in a claim should not be construed as limiting the claim concerned.
