The water treatment process comprises the following steps: taking dehumidification in summer as an example, cooling water (assuming 7 ℃) generated by the air source/ground source heat pump 5 is firstly input from the cold and heat source water inlet pipe 22, at this time, the first three-way valve 221 is used for leading the cooling water which enters into the cold and heat source water inlet pipe 22 into the dehumidification surface cooler 312, after flowing through the dehumidification surface cooler 312, the cooling water returns to the cold and heat source water inlet pipe 22 (assuming 10 ℃) at this time, and then flows into the first heat exchanger 11 to exchange heat with water (assuming 22 ℃) flowing in the water collecting and distributing water inlet pipe 25, so that the temperature of the water in the water collecting and distributing water inlet pipe 25 is reduced, then the water is input into the water distributing and distributing device 4 through the explosion-proof valve 242 by the water pressure of the water distributing device 242, then the water distributing and distributing the water distributing device 4 through the capillary 41 in each room, the temperature in the room is regulated by the capillary 41, and the water in the capillary 41 and the room temperature is subjected to heat exchange again from the water collecting and water distributing and water in the room 25 returns to the second heat exchanger 21, so as to perform continuous heat exchange circulation. When the temperature sensor 261 in the water collecting and discharging pipe 24 senses that the temperature is lower in the summer in a refrigerating state, the proportional integral valve 26 is controlled to increase the amount of water in the water collecting and discharging pipe 25 entering the water collecting and discharging pipe 24, so that the temperature output to the water collecting and discharging device 4 is increased through the water in the water collecting and discharging pipe 25; in contrast, when the temperature sensor 261 senses that the temperature is high, the proportional integral valve 26 is controlled to reduce the amount of water flowing into the separate water inlet pipe 25 and the separate water outlet pipe 24, thereby reducing the temperature of the water. Due to the arrangement of the three-way valve II 251 on the water collecting and distributing water inlet pipe 25, the water returned from the capillary tube 41 is sequentially introduced into the temperature-rising surface cooler 313 and the precooling surface cooler 311 under the action of the three-way valve II 251, then flows back into the water collecting and distributing water inlet pipe 25, and is introduced into the second heat exchanger 21.
The air treatment process comprises the following steps:
first case: the first electric air valve 161 is in a closed state, the second electric air valve 151 is in an open state, and the third electric air valve 141 is in a closed state. The exhaust centrifugal fan 131 starts to work, so that indoor cold air (assumed to be 20 ℃) is pumped into the indoor air return opening 13 and then is exhausted from the outdoor exhaust duct 15 through the first heat exchanger 11, and the exhaust centrifugal fan 131 is arranged at the indoor air return opening 13, so that the indoor air can be forcefully pumped out for timely replacement; meanwhile, the air supply centrifugal fan 3211 works so as to enable the interior of the dehumidifying air duct 31 to be in negative pressure, and further generate negative pressure for the outdoor fresh air inlet 12, so that external air (assumed to be 30 ℃) can enter the air treatment box 1 from the outdoor fresh air inlet 12, then is sequentially discharged into the dehumidifying box 3 from the indoor air supply duct 14 through the other channel of the first heat exchanger 11, when outdoor fresh air passes through the first heat exchanger 11, the outdoor fresh air has higher temperature relative to indoor air, so that heat exchange can be carried out between the outdoor fresh air and indoor cold air in the first heat exchanger 11, the temperature of the outdoor fresh air is reduced (assumed to be 22 ℃) after the temperature is reduced, cold air to be discharged is fully utilized, and because the electric air valve one 161 and the electric air valve three 141 are in a closed state, the outdoor fresh air is directly and completely introduced into the dehumidifying air duct 31, the introduced fresh air is contacted with the precooling surface cooler 311, the water (the temperature is 13 ℃) in the precooling surface cooler 311 performs precooling dehumidification on the air, so that the temperature of a part of fresh air is reduced (the temperature of the fresh air is 16 ℃ after the fresh air is reduced at the moment), then the fresh air is contacted with the dehumidifying surface cooler 312, and the fresh air is contacted with the dehumidifying surface cooler 312 through cooling water (7 ℃) so that condensation can be condensed when the fresh air is contacted with the dehumidifying surface cooler 312, the condensed water drops fall on the water receiving disc 33 and are discharged out of the dehumidifying box 3 through the water discharging pipeline 331, the fresh air is dehumidified, the dehumidified fresh air (10 ℃) is contacted with the heating surface cooler 313, since the water (20 ℃) in the temperature rising surface cooler 313 is cooled (13 ℃) after the temperature of the air passing through the dehumidifying surface cooler 312 is raised, the temperature of the water in different position areas is reasonably utilized in such a way, the energy is fully utilized, and the fresh air is dehumidified by preferentially utilizing the cooling water, so that the use of a compressor is reduced by reasonably utilizing the cold source of the water treatment.
Second case: the indoor air is not excluded and is internally circulated, wherein the water treatment process and the air treatment process are consistent with those of the first condition, except that the first electric air valve 161 in the initial state is in an opened state, the second electric air valve 151 is in a closed state, and the third electric air valve 141 is in a closed state, so that the air from the indoor air inlet 13 is introduced into the indoor air delivery duct 14 through the first electric air valve 161 after passing through the first heat exchanger 11, and then is introduced into the indoor air from the indoor air delivery port 321 again through the dehumidifying air duct 31, the indoor air is recycled, the temperature of the indoor air can be fully utilized, the heat loss after heat exchange is reduced, and on the other hand, the circulated air is continuously circulated and dehumidified, so that the humidity can be well controlled. When the carbon dioxide content in the air is increased due to multiple circulation of the indoor air, when the air passes through the indoor air return opening 13, and the carbon dioxide sensor 132 senses that the carbon dioxide content in the air is greater than a set value, the electric air valve I161 is driven to be closed, the electric air valve II 151 is driven to be opened at the moment, and then the indoor air is discharged from the outdoor exhaust duct 15, and fresh air is sent into the room from the indoor air supply opening 321 after passing through the dehumidification air duct 31.
Third case: when dehumidification is not needed, cooling water entering from the cold and heat source water inlet pipe 22 directly enters the second heat exchanger 21 through the first three-way valve 221 and does not pass through the dehumidification surface cooler 312; similarly, the water entering from the water collecting and separating water inlet pipe 25 also directly enters the second heat exchanger 21 and does not pass through the pre-cooling surface cooler 311 and the heating surface cooler 313; meanwhile, the electric air valve III 141 is opened, so that the air entering the indoor air delivery duct 14 can pass through the dehumidifying air duct 31 and the non-resistance air channel 32 at the same time, thereby accelerating the circulation speed of the air, and the non-resistance air channel 32 can allow the air to pass through quickly, and the dehumidifying air duct 31 has a certain resistance to the flow speed of the air due to the arrangement of the precooling surface cooler 311, the dehumidifying surface cooler 312 and the heating surface cooler 313, thereby accelerating the circulation of the air through the non-resistance air channel 32.
The present embodiment is only for explanation of the present invention and is not to be construed as limiting the present invention, and modifications to the present embodiment, which may not creatively contribute to the present invention as required by those skilled in the art after reading the present specification, are all protected by patent laws within the scope of claims of the present invention.
