On the daytime in summer, closed type heat source tower A is equivalent to cooling tower and takes away the condensation heat of source pump J, carries
High condensation efficiency；At night, closed type heat source tower A is equivalent to evaporation cooling handpiece Water Chilling Units, produces high temperature cold water
And be stored in cold-storage tank B, for daytime.In winter, closed type heat source tower A is as source pump J
Thermal source, improve source pump heating efficiency.The return air of outdoor new wind and air-conditioned room C is by airduct group
Enter in closed type heat source tower A, after heat exchange again by blower fan 5 outside exhaust outlet discharge chamber.
The closed type heat source tower heat pump that energy regenerating of the present invention and water cold storage combine is united with evaporation cooling empty
The work process of adjusting system is as follows:
Particularly may be divided into three kinds of mode of operations, specific as follows:
1) water cold storage at night pattern:
At cooling season, during cold-storage at night, as in figure 2 it is shown, source pump J is out of service, closed type hot
Source tower A (being now equivalent to enclosed evaporation cooling handpiece Water Chilling Units) starts working:
Open the first valve V1 and the 4th valve V4, close the second valve V2, the 3rd valve V3,
Five valve V5 and the 6th valve V6；Close the 3rd water circulating pump b3, open the first water circulating pump b1 and
Second water circulating pump b2, now recirculated water is sent to water-locator along the first water distributor h1, the second water distributor h2
7 spray；Then, closing air returning valve 3, open new air-valve 2, outdoor new wind is by new wind entrance 1
Enter blast pipe 12, after filter 11 filters, enter closed type heat source tower A, with heat exchange coil 9 and filling out
Expect that the moisture film on 8 surfaces carries out hot and humid area；Heat exchange coil 9 is fallen after trickle is cooled in filler 8
Surface, continues to carry out hot and humid area with air so that the Sprayer Circulation coolant-temperature gage outside heat exchange coil 9 enters one
Step reduces；In heat exchange coil 9 recirculated water by coil pipe wall with heat exchange coil 9 outside Sprayer Circulation water carry out
Heat exchange, produces high temperature cold water by the first water pipe G1, the second water pipe G2, the 3rd water pipe G3 and the
Four water pipe G4 are stored in cold-storage tank B.
2) cooling mode:
At cooling season, when daytime needs cooling, can by cold-storage tank B store high temperature cold water or
The low-temperature cold water that source pump J is produced provides cold in air-conditioned room C；
At the cooling initial stage, by cold-storage tank B to air-conditioned room C cooling, reduce the operation of source pump J
Time, reduce air conditioning energy consumption；Now, closed type heat source tower A does not runs with source pump J；
Close the 7th valve V7, open the 5th valve V5 and the 6th valve V6, close the first recirculated water
Pump b1 and the second water circulating pump b2, opens the 3rd water circulating pump b3, at the band of the 3rd water circulating pump b3
Under Dong, high temperature cold water is delivered to air-conditioning end by cold-storage tank B along the 7th water pipe G7, the 12nd water pipe G12
End device D, backwater returns to cold-storage tank B through the 9th water pipe G9, the tenth water pipe G10.
When the cold that the high temperature cold water in cold-storage tank B can not meet air-conditioned room requires, source pump
J and closed type heat source tower A (being now equivalent to closed cooling tower) starts working: close the second valve V2,
Second valve V4, the second valve V5 and the second valve V6, open the 3rd valve V3, the 7th valve
V7 and the 8th valve V8, opens the first water circulating pump b1, the second water circulating pump b2 and the 3rd recirculated water
Pump b3；Regulate new air-valve 2 and the aperture of air returning valve 3, make outdoor new wind with indoor return air with certain proportion
Closed type heat source tower A (being now equivalent to closed cooling tower) is entered after mixing；
The principle producing cooling water is identical with cold-storage at night: cooling water is under the first water circulating pump b1 drives
Entering condenser E along the first water pipe G1, the 5th water pipe G5, take away the heat of condenser E, cold water exists
Condenser E returns to heat exchange coil 9 along the 6th water pipe G6, the 4th water pipe G4 after heat exchange again carry out
Heat exchange circulation；The freezing water that source pump J is produced under the drive of the 3rd water circulating pump b3,
Delivered in air-conditioner tail end equipment D by vaporizer G along the 11st water pipe G11, the 12nd water pipe G12,
In absorption chamber wet more than waste heat after, backwater along the 9th water pipe G9, the 13rd water pipe G13 enter vaporizer G
Carry out heat exchange circulation.
3) heat supply mode:
When heating season needs heating, closed type heat source tower A as the low-grade heat source of source pump J, to
Source pump J provides stable heat；Temperature sensor 10 is for monitoring the temperature on heat exchange coil 9 surface
Degree:
When the surface temperature of heat exchange coil 9 is more than the dew point temperature of the mixing air entering closed type heat source tower A
And during more than zero degree, the solution spraying system of closed type heat source tower A does not works；Now, the first valve is closed
Door V1, the second valve V2, the 4th valve V4, the 5th valve V5 and the 6th valve V6, open the
Three valve V3, the 7th valve V7 and the 8th valve V8, close the second water circulating pump b2, opens first
Water circulating pump b1 and the 3rd water circulating pump b3；Regulate new air-valve 2 and the aperture of air returning valve 3, make outdoor
New wind enters closed type heat source tower A, by the pipe of heat exchange coil 9 after mixing with certain proportion with indoor return air
Wall carries out heat exchange, after transferring heat to anti-icing fluid, at blower fan 5 with the anti-icing fluid in heat exchange coil 9
Discharged by exhaust outlet under effect；Through heat exchange, anti-icing fluid temperature raises, the first water circulating pump b1's
Enter the vaporizer E of source pump J along the first water pipe G1, the 5th water pipe G5 under drive, after heat release,
Return to heat exchange coil 9 along the 6th water pipe G6, the 4th water pipe G4 and carry out heat exchange circulation；Cold-producing medium exists
Circulation in source pump J, the air conditioning hot produced is under the drive of the 3rd water circulating pump b3, by evaporating
Device G sends into air-conditioner tail end equipment D along the 11st water pipe G11, the 12nd water pipe G12, after heat release,
Return to vaporizer G along the 9th water pipe G9, the 13rd water pipe G13 and be circulated heat exchange.
When temperature sensor 10 monitors the surface temperature of heat exchange coil 9 less than entering closed type heat source tower A
The dew point temperature of mixing air, but during higher than zero degree, the solution spraying system of closed type heat source tower A is still
Do not work, condense water separating system and be automatically drained out the condensed water on heat exchange coil 9 surface.Work as temperature sensor
10 surface temperature dew points less than the mixing air entering closed type heat source tower A monitoring heat exchange coil 9
Temperature, and during less than zero degree, the solution spraying system starts of closed type heat source tower A, changes to reduce
The freezing point on hot coil 9 surface, prevents heat exchange coil 9 surface frosting, provides stable for source pump J
Thermal source, it is ensured that source pump J safe and highly efficient operation.Now, the second valve V2 and second circulation is opened
Water pump b2, anti-icing fluid sprays the steam in heat exchange coil 9 Surface absorption air, and anti-icing fluid is thinning,
Anti-icing fluid after thinning enters evaporation along the first solution spraying pipe r1 under the drive of the second water circulating pump b2
Device G, heated tailing edge the second solution spraying pipeline r2 enter water-locator 7 and spray, at filler 8
In, the air of low temperature and low humidity and hot solution carry out hot and humid area, and air humidity content increases, and anti-icing fluid thickens,
Realizing regeneration, concentrated solution is fallen heat exchange coil 9 surface and is continued as the thermal source that source pump J provides stable.
User side air conditioning hot circulation theory is identical.
