Specific implementation process：Air-treatment and water process are mutual indepedent, therefore are separately illustrated herein.
Water treatment procedure：It is illustrated so that summer dehumidifies as an example, the cooling generated first by air-source/earth source heat pump 5
Water（It is assumed to be 7 DEG C）It is inputted from Cooling and Heat Source water inlet pipe 22, triple valve 1 at this time will go into Cooling and Heat Source water inlet pipe 22
Cooling water is passed into dehumidifying surface cooler 312, is returned in Cooling and Heat Source water inlet pipe 22 after being flowed through in dehumidifying surface cooler 312
（Assuming that being 10 DEG C at this time）, then it is flowed into the water with circulation in diversity water water inlet pipe 25 in First Heat Exchanger 11（It is assumed to be 22
℃）Heat exchange is carried out, water pump is input to from diversity water outlet pipe 24 after the temperature to reduce water in diversity water water inlet pipe 25
241, water is input to by explosion-proof valve 242 in water collecting and diversifying device 4 by the hydraulic pressure of water pump 241, then by water collecting and diversifying device 4 by moisture
The capillary 41 being fitted in each room adjusts the temperature in room, the water in capillary 41 and room by capillary 41
Interior temperature carries out back flowing into the 21 interior progress of the second heat exchanger constantly from diversity water water inlet pipe 25 again after heat exchange
Heat exchange cycle.When summer is in refrigerating state, when the temperature sensor 261 in diversity water outlet pipe 24 senses that temperature is relatively low
When, the water that just control proportional integration valve 26 increases in diversity water water inlet pipe 25 at this time enters the amount in diversity water outlet pipe 24, from
And the temperature for being output to water collecting and diversifying device 4 is improved by the water in diversity water water inlet pipe 25；On the contrary, when temperature sensor 261 is felt
When should arrive temperature drift, just control proportional integration valve 26 reduces in diversity water water inlet pipe 25 and is flowed into diversity water outlet pipe 24 at this time
Interior water, to reduce the temperature of water.And due to the setting of the triple valve 2 251 on diversity water water inlet pipe 25, make from capillary
Pipe 41 be back to come water under the action of triple valve 2 251 successively be passed into heating surface cooler 313, precooling surface cooler 311 it
It is passed into the second heat exchanger 21 after being back to again afterwards in diversity water water inlet pipe 25.
Air handling process：
The first situation：Electric air valve 1 is closed, and Electric air valve 2 151 is in open state, Electric air valve three
141 are closed.Air draft centrifugal blower 131 is started to work, thus by indoor cold air（It is assumed to be 20 DEG C）It is pumped into
In indoor return air mouth 13, then passes through First Heat Exchanger 11 and be discharged from outdoor exhausting duct 15, the setting of air draft centrifugal blower 131 exists
Indoor return air mouth 13 can be strong indoor air extraction timely replaced；Meanwhile 3211 work of centrifugal blower of blowing
Make, to make to be in negative pressure in dehumidifying air duct 31, and then a negative pressure is also generated to outdoor fresh air air inlet 12 so that extraneous
Air（It is assumed to be 30 DEG C）It can be entered in air-treatment case 1 from outdoor fresh air air inlet 12, then pass sequentially through first and change
An other channel for hot device 11 is drained into from indoor air delivery duct 14 except in wet tank 3, the fresh air in outdoor exchanges heat by first
When device 11, outdoor fresh air is higher temperature relative to indoor air, therefore can be with interior in First Heat Exchanger 11
Cold air carry out heat exchange, to reduce the temperature of outdoor fresh air（Assuming that being 22 DEG C after reducing）, to take full advantage of
The cold air for preparing discharge, since Electric air valve 1, Electric air valve 3 141 are in the state of closing, outdoor fresh air
It is directly all passed into dehumidifying air duct 31, the fresh air being passed through is contacted with precooling surface cooler 311, and the water in surface cooler 311 is pre-chilled
（Temperature is 13 DEG C）Precooling dehumidifying is carried out to air, to reduce the temperature of a part of fresh air（Assuming that fresh air after reducing at this time
Temperature is 16 DEG C）, later fresh air again with dehumidifying surface cooler 312 contact, due to dehumidifying surface cooler 312 in circulate be cooling water
（It is assumed to be 7 DEG C）, therefore fresh air when being contacted again with dehumidifying surface cooler 312 can condensation and dewfall, the water droplet of moisture condensation falls on drip tray
It is discharged in addition to wet tank 3 on 33 and by drainage pipeline 331, to play the role of dehumidifying to fresh air, after then dehumidifying
Fresh air（It is assumed to be 10 DEG C）It is contacted again with heating surface cooler 313, due to the water in heating surface cooler 313（20℃）To passing through
Temperature reduces after the air of dehumidifying surface cooler 312 is heated up（13℃）It is flowed into again in precooling surface cooler 311, with such
The temperature of the water in different location region is reasonably utilized in mode, takes full advantage of the energy, and by preferentially utilizing cooling water
It dehumidifies to fresh air, the use of compressor is reduced to reasonably be utilized the low-temperature receiver of water process.
The second situation：Room air is not excluded for and carries out interior cycle, water treatment procedure and air handling process therein
It is consistent with the process of the first situation, the difference is that the Electric air valve 1 of original state is in open state, Electric air valve two
151 are closed, and Electric air valve 3 141 is closed, and therefore, coming from for entering from indoor return air mouth 13 is indoor
Air by being passed into indoor air delivery duct 14 by Electric air valve 1 after First Heat Exchanger 11, then using except
Wet wind road 31 is again fed to interior from indoor air outlet 321, and indoor air is reused, Interior Space is can make full use of
The temperature of gas reduces the thermal loss after heat exchange, and on the other hand, the air of cycle is constantly carrying out circulating dehumidification, therefore
Humidity can be controlled preferably.When room air repeatedly recycles and the carbon dioxide content in air is caused to increase, when air passes through
When crossing indoor return air mouth 13, when carbon dioxide sensor 132 senses that the carbon dioxide content in air is greater than the set value, at this time
Just driving Electric air valve 1 is closed, Electric air valve 2 151 is opened, and then indoor air is allowed to be discharged from outdoor exhausting duct 15,
Allow fresh air by being sent to interior from indoor air outlet 321 after air duct 31 of dehumidifying.
The third situation：When that need not be dehumidified, the cooling water entered from Cooling and Heat Source water inlet pipe 22 directly passes through three
Port valve 1 enters the second heat exchanger 21, without using dehumidifying surface cooler 312；Likewise, from diversity water water inlet pipe 25
The water of entrance also enters directly into the second heat exchanger 21, will not be using precooling surface cooler 311 and heating surface cooler 313；Simultaneously
Electric air valve 3 141 is opened, and keeps the wind energy for entering indoor air delivery duct 14 enough simultaneously by dehumidifying air duct 31 and without choke channel
32, to accelerate the velocity of liquid assets of air, and without choke channel 32 can for air quickly through, and in air duct 31 of dehumidifying by
In precooling surface cooler 311, dehumidifying surface cooler 312, heat up surface cooler 313 setting and to the flow velocity of air have certain resistance
Power, thus air circulation is accelerated by no choke channel 32.
