Change the flow direction of refrigerant.In this mode, refrigerant goes out to flow through solenoid valve 216 by the C-terminal mouth of four-way reversing valve 4, then according to
The secondary filter 211 that enters filters, and throttles using expansion valve 212, refrigerant temperature and pressure reduce rapidly, and become low-temp low-pressure shape
State enters heat source side plate heat exchanger 5 after check valve 213, and refrigerant evaporates in heat source side plate heat exchanger 5, absorbs
In the water for flowing through heat exchanger by heat source side water inlet 27, heat source side is flowed out by heat source side water outlet 28 by the water of absorption heat
Plate heat exchanger 5.The refrigerant 30 for absorbing heat enters the ends A of four-way reversing valve 4 after going out in heat source side plate heat exchanger 5
Mouthful, then go out the ports D into exchange type liquid storage device 6 from the ports B, return to compression after going out from the ports G of exchange type liquid storage device 6
Machine 1 completes the exothermic cyclic process of once heat absorption of refrigerant, realizes the heat absorption heat release to water, has reached independent heat production water
Purpose.
2 pairs of sea water source heat pump trilogy supply units' installation uses are described in detail below in conjunction with the accompanying drawings.
Job description：In conjunction with sea water source heat pump trilogy supply unit " separate refrigeration ", " refrigeration+heat production water ", " individually heating ",
Five kinds of operating modes of " heating+heat production water ", " independent heat production water ", entirely installing corollary system also has different patterns.
A, separate refrigeration：Sea water source heat pump trilogy supply unit is run under separate refrigeration pattern, the production of unit internal heat resource side
Heat water goes out from heat source side outlet pipe 2-3, rejects heat in the seawater of seawater pond 2-2.Cold water in seawater pond passes through again
The effect of heat source side circulating pump 2-4 enters sea water source heat pump trilogy supply unit 2-1 by condenser heat band from heat source side water inlet pipe 2-5
Into seawater.Under the pattern is air conditioner refrigerating side using side.The refrigerated circulating water of air-conditioning system is air-conditioning side circulating pump 2-7's
Under effect, tail-end blower fan coil pipe 2-6 is got in, chilled water reduces indoor temperature to reach indoor system from indoor absorption heat
Cold purpose.Hot water side does not start operation under the pattern, is finally equivalent to room through sea water source heat pump trilogy supply unit 2-1
Interior heat carrying is discharged into seawater, to achieve the purpose that indoor refrigeration.
B, refrigeration+heat production water：Sea water source heat pump trilogy supply unit is run under refrigeration+heat production aqueous mode, heat inside unit
Source generates hot water, goes out from heat source side outlet pipe 2-3, rejects heat in the seawater of seawater pond 2-2.Cold water in seawater pond
Entering sea water source heat pump trilogy supply unit 2-1 from heat source side water inlet pipe 2-5 by the effect of heat source side circulating pump 2-4 again will condense
Heat takes in seawater.Under the pattern is air conditioner refrigerating side using side.The refrigerated circulating water of air-conditioning system is recycled in air-conditioning side
Under the action of pumping 2-7, tail-end blower fan coil pipe 2-6 is got in, chilled water reduces indoor temperature to reach from indoor absorption heat
The purpose of indoor refrigeration.Meanwhile the life water in hot water thermal insulating water tank 2-13 is entered by the effect of hot water side circulating pump 2-11
Unit enters hot water guarantor by going out unit from hot water side outlet pipe 2-10 after unit internal hot-water side board type heat exchanger draw heat
Reservoir, produced domestic hot-water are stored in hot water thermal insulating water tank.By hot water feeding pipe by delivery to needing to use
The place of hot water supplements cold water by cold water water supply pipe.It will be indoor by sea water source heat pump trilogy supply unit 2-1 under the pattern
Heat, which is transferred in hot water, generates domestic hot-water, and extra heat is discharged into seawater in the case where meeting hot water demand,
It is finally reached indoor refrigeration while recycling the purpose of heat heat production water.
C, individually heating：Sea water source heat pump trilogy supply unit 2-1 is run under independent heating mode, in heat source side circulating pump
Under the action of 2-4, seawater enters unit from heat source side water inlet pipe 2-5, and for unit after absorbing heat in seawater, seawater passes through heat source
Side outlet pipe 2-3 is returned in seawater pond.In air-conditioning side, unit will be discharged into from the heat absorbed in seawater in air-conditioning side, air-conditioning
System circulating water gets in tail-end blower fan coil pipe 2-6 under the action of the circulating pump 2-7 of air-conditioning side, will be in Air-conditioning Cycle hot water
Heat be discharged into indoor to achieve the purpose that indoor heating, recirculated water returns to unit by air-conditioning side water inlet pipe 2-9 again to be continued
Heat absorption, completes the cycle of water system.
D, heating+heat production water：Sea water source heat pump trilogy supply unit is run under heating+heat production aqueous mode, is followed in heat source side
Under the action of ring pumps 2-4, unit draw heat from the water that heat source side water inlet pipe 2-5 enters unit is drawn the seawater of heat
It is returned in the 2-2 of seawater pond by heat source side outlet pipe 2-3.In air-conditioning side, the heat that a part is absorbed from seawater is by air-conditioning side
Recirculated water absorbs, and by the effect of air-conditioning side circulating pump 2-7, end indoor fan coil pipe 2-6 is rejected heat to, to reach room
The purpose of interior heating discharges the air-conditioner circulating water after heat and is returned to inside unit by air-conditioning side water inlet pipe 2-9 again and continues to absorb heat.
At the same time, another part heat absorbed from seawater is absorbed by the recirculated water of hot water side, and institute's heat production water is in hot water circulating pump
Enter hot water thermal insulating water tank 2-13 storage under the action of 2-11, when needing using hot water, by hot water feeding pipe 2-15 by hot water
Corresponding places are transported to, cold water is supplemented by cold water water supply pipe 2-14.This pattern absorbs heat from seawater, meets heating simultaneously
The demand of supplying hot water.
E, independent heat production water：Sea water source heat pump trilogy supply unit is run under independent heat production aqueous mode, is recycled in heat source side
Under the action of pumping 2-4, unit draw heat from the water that heat source side water inlet pipe 2-5 enters unit, the seawater for being drawn heat leads to
Heat source side outlet pipe 2-3 is crossed to return in the 2-2 of seawater pond.The heat absorbed from seawater is absorbed by the recirculated water of hot water side, is produced
Hot water enters the 2-13 storages of hot water thermal insulating water tank under the action of hot water circulating pump 2-11 and passes through hot water when needing using hot water
Feed pipe 2-15 supplements cold water by delivery to corresponding places, by cold water water supply pipe 2-14.This pattern is absorbed from seawater
Heat meets the needs of heating while supplying hot water.
