Cooling water collect after enter in the second return pipe 9, enter the followed by y-type filter 19, butterfly valve 17, rubber soft joint 14
Two-cycle pump 21, the chilled water flowed out from second circulation water pump 21 is through rubber soft joint 14, pressure gauge 15, check-valves 23, butterfly
Cooling end 5 is flowed back to after valve 17, butterfly valve 17, electric water treatment device 22, butterfly valve 17, thermometer 16, pressure gauge 15, rubber soft joint 14
It is interior.
3, additional soft wa ter process：
Tap water is introduced into automatical softener 27 and is softened, and the water after softening sequentially enters softened water tank 28, console mode expansion
Water tank 29, the water in console mode expansion tank 29 enter chilled water water collector 26 by hose.
Two, it when transition season, when transition season outdoor temperature requires low 4 DEG C of temperature or more than workshop technique, and gives birth to
It produces in workshop since equipment, personnel etc. are radiated, causes temperature in workshop to be higher than the temperature that technique requires, at this moment utilize heat-exchanger rig
2 freeze
1, water circulation path is freezed：
Under the action of first circulation water pump 18, chilled water flows into third outlet pipe 10 from the refrigeration area of heat-exchanger rig 2, then flows
The first outlet pipe 6 is flowed into after rubber soft joint 14, pressure gauge 15, thermometer 16, butterfly valve 17, then different refrigeration machines 1 is cold
Freeze after water pools together and is co-flowed into freezing water separator 25, multiple diverter branch streams of the chilled water from freezing water separator 25
It to cold end, is pooled in chilled water water collector 26 from the chilled water flowed out with cold end, is then flowed into from chilled water water collector 26
To the first return pipe 7, flows through gate valve 20, y-type filter 19, pressure gauge 15, rubber soft joint 14 and enters first circulation water pump 18,
The chilled water flowed out from first circulation water pump 18 flows into third after rubber soft joint 14, pressure gauge 15, check-valves 23, butterfly valve 17
Return pipe 11 then flows through the refrigeration area that heat-exchanger rig 2 is flowed back to after butterfly valve 17, thermometer 16, pressure gauge 15, rubber soft joint 14
It is interior.
2, cooling water circulation path：
Under the action of second circulation water pump 21, cooling water flows into the 4th outlet pipe 12 from the cooling zone of heat-exchanger rig 2, then flows
The second outlet pipe 8 is flowed into after rubber soft joint 14, pressure gauge 15, thermometer 16, butterfly valve 17, then flows into corresponding cooling
In tower 3, the cooling water flowed out from cooling tower 3 enters in the second return pipe 9 after collecting, followed by y-type filter 19, butterfly valve
17, rubber soft joint 14 enter second circulation water pump 21, from second circulation water pump 21 flow out chilled water through rubber soft joint 14,
After pressure gauge 15, check-valves 23, butterfly valve 17, butterfly valve 17, electric water treatment device 22 flow into the 4th return pipe 13, flow through butterfly valve 17,
It is flowed back in the cooling zone of heat-exchanger rig 2 after thermometer 16, pressure gauge 15, rubber soft joint 14.
Low 4 DEG C of temperature or more are required than workshop technique in transition season outdoor temperature, temperature is higher than technique in workshop
It is required that when, cooled down using outdoor heat-exchanger rig 2 to workshop, energy caused by being run this reduces refrigeration machine 1
Consumption, has saved the energy.
Since the cooling water in cooling water recirculation system contains a certain amount of scale, along with cooling water is in cooling tower 3
When carrying out hot and humid area with outdoor air, dust and impurities and bacterium in atmosphere enter cooling water recirculation system in large quantities.
As cooling water constantly scatters and disappears to outdoor in cooling tower, needs continuously to supplement the water in system, make
At in system scale and sludge quantity constantly accumulate.Scale and sludge can be attached to the heat exchange of 1 condenser of refrigeration machine in system
On tube wall.Since the thermal coefficient of calcium carbonate is 0.05w/mk, the thermal coefficient of red copper is 14.6w/mk, the scale of 1mm thickness,
Energy consumption can be made to rise 10~16%.With the increase of scale and sludge thickness on heat exchanger tube, the heat transfer effect of condenser is sharply disliked
Change, ultimately causes refrigerating capacity and sharply decline.Y-type filter 19, the lower inclined portion of y-type filter 19 are set on the second return pipe 9
Be connected with butterfly valve 17, motor-driven valve 24, scale and sludge are filtered at y-type filter 19, pass through the lower inclined portion of y-type filter 19 and connect
Butterfly valve 17, the motor-driven valve 24 connect is discharged, it is possible to prevente effectively from scale and sludge are in 1 condenser heat-exchange pipes wall of refrigeration machine.
The present invention is recycled using tank-free type cooling water, and second circulation water pump 21 is only needed when making cooling water circular flow
The resistance of pipe system for overcoming pipe network in pipe-line system, valve, elbow and cooling tower 3 etc., without providing cooling water from water
Water face is delivered to the energy consumption of water outlet in cooling tower 3.
It is respectively connected with balanced valve 30 between second outlet pipe 8 of different refrigeration units, between the second return pipe 9, when wherein
All the way or a few routings in water flow variation and when causing the variation of branch pressure, balanced valve 30 automatically adjusts the water of the branch
Flowing pressure, it is ensured that each branch water flow pressure keeps the amplitude of fluctuation little, effectively avoids each branch even phenomenon uneven in temperature
Occur.
The above-described embodiments merely illustrate the principles and effects of the present invention, and is not intended to limit the present invention.It is any ripe
The personage for knowing this technology all without departing from the spirit and scope of the present invention, carries out modifications and changes to above-described embodiment.Cause
This, institute is complete without departing from the spirit and technical ideas disclosed in the present invention by those of ordinary skill in the art such as
At all equivalent modifications or change, should be covered by the claims of the present invention.
