Described water collector is also provided with the branch line of connecting plate type heat exchanger, this branch line connects successively circulating pump, motor-driven valve c;
Described cold-storage tank is also provided with the branch line of connecting plate type heat exchanger, this branch line is provided with successively and lets cool pump, motor-driven valve e, the cold-storage tank connected successively, let cool pump, motor-driven valve e, plate type heat exchanger and motor-driven valve k, then return cold-storage tank composition and let cool loop;

When motor-driven valve b and motor-driven valve c closes, chilled water storage system switches to refrigerator direct-furnish mode operation, now, after the workshop backwater entering water collector is delivered to refrigerator cooling by refrigerator primary pump, be delivered to water knockout drum again, supplying water as workshop is supplied to workshop use.
One end of refrigerator also connects cold-storage tank and cold-storage pump successively and forms the second cold-storage loop.
The second described cold-storage loop, by the cold-storage tank connected successively by pipeline, motor-driven valve l, cold-storage pump, motor-driven valve m, refrigerator, motor-driven valve h and motor-driven valve g, then returns cold-storage pump composition;
When transition season and winter, chilled water storage system carries out cold-storage mode operation, and motor-driven valve h, motor-driven valve g and motor-driven valve m close, and now cold-storage tank carries out cold-storage by the first cold-storage loop works;
When in summer, chilled water storage system carries out cold-storage mode operation, and motor-driven valve b, motor-driven valve d, motor-driven valve e, motor-driven valve f, motor-driven valve i and motor-driven valve k close, now, second cold-storage loop works, the water flowed out from cold-storage tank is cooled to refrigerator by cold-storage transport pump, then returns cold-storage tank.
Summer is because large by refrigeration duty, workshop return water temperature is high, coolant-temperature gage through cryocooled is also relatively high, the temperature (i.e. the first cold-storage loop) of needs cannot be dropped to again by the plate water of changing commanders in cold-storage tank, therefore summer can only with traditional cold-storage pattern (namely the second cold-storage loop be that high-temperature water in cold-storage tank returns cold-storage tank through refrigerator cooling, has nothing to do with workshop water system).And conditioning in Transition Season and winter because of workshop refrigeration duty little, workshop return water temperature is also low, and the coolant-temperature gage through refrigerator cooling is also low, drops to the temperature of needs by the plate water of changing commanders in cold-storage tank.Therefore go balance cold-storage refrigeration duty and workshop refrigeration duty at conditioning in Transition Season and winter (when workshop refrigeration duty is large by regulating the frequency of cold-storage pump, turn down the frequency of cold-storage pump, the cold that workshop chilled water is obtained increases, and the cold that cold-storage obtains reduces; When workshop refrigeration duty diminishes, increase the frequency of cold-storage pump, the cold that workshop chilled water is obtained reduces, and the cold that cold-storage obtains increases) therefore normally only need operation first cold-storage loop at conditioning in Transition Season and winter, and do not need operation second cold-storage loop.
Summer because not by plate heat exchange, the object that plate also just cannot be utilized to change reach partition two kinds of water systems (namely go here and there water).Conditioning in Transition Season and winter, because can utilize plate heat exchange, utilize plate heat exchange to reach the object as far as possible reducing string waterside number so as much as possible.
Cold-storage parameter is illustrated: the cold water temperature that cold-storage tank needs is 5 DEG C, and therefore when cold-storage, the water outlet temperature setting value of refrigerator is 5 DEG C, and the chilled water temperature that plant process requires is 10 DEG C, and the chilled water temperature difference that refrigerator is produced is 5 DEG C.The chilled water supply water temperature required because of workshop is 10 DEG C, so just can not re-use when the water temperature in cold-storage tank reaches 10 DEG C when letting cool, so letting cool the water temperature difference terminated in rear cold-storage tank is seldom 10 DEG C..During summer, workshop return water temperature is many at 13 ~ 15 DEG C, then many at 8 ~ 10 DEG C through the cooled leaving water temperature of refrigerator, substantially meet workshop supply water temperature requirement, but the water for cooling to 5 will changed commanders in cold-storage tank by plate DEG C is obviously infeasible; In conditioning in Transition Season and winter, workshop return water temperature can control at 10,11 DEG C, even lower, then how even lower at 5 ~ 6 DEG C by the cooled leaving water temperature of refrigerator, about the water for cooling to 5 of therefore changing commanders in cold-storage tank by plate DEG C.
When needing cold-storage after letting cool end, according to the second cold-storage pattern, because the water temperature in cold-storage tank is at about 10 DEG C, therefore the inflow temperature of refrigerator is 10 DEG C, and along with the carrying out of cold-storage, in cold-storage tank, the temperature of water is more and more lower, the inflow temperature of refrigerator also can be more and more lower, and refrigerator leaving water temperature remains unchanged, so refrigerator load can be more and more less, refrigerating efficiency can be worse and worse.According to the first cold-storage pattern, although the water temperature in cold-storage tank worse and worse, because the use refrigeration duty in workshop also born by refrigerator, so refrigerator efficiency is higher than the second cold-storage pattern.
Compared with prior art, chilled water storage system of the present utility model has the following advantages:
(1) fundamentally stop string water phenomenon to occur, chilled water is avoided to waste: when when transition season and winter, chilled water storage system is when carrying out cold-storage mode operation, first cold-storage loop works, carry out cold-storage, now only motor-driven valve h17 and motor-driven valve m22 two motor-driven valves need be closed always (prevent valve repeatedly switch cause sealed ring deformation or wearing and tearing to cause going here and there water, the way more insured adds a hand-operated valve more respectively on each motor-driven valve side, hand-operated valve also cuts out), just the water system in cold-storage tank and plant process chilled water system thoroughly can be separated, the water of high pressure systems (workshop chilled water) is prevented to enter the water (water in cold-storage tank) of low-pressure system, fundamentally solve the phenomenon of string water, and do not affect normal cold-storage pattern and let cool pattern switching,
(2) energy is saved: when transition season and winter, the utility model is in process of cool, workshop backwater after the heat exchange of plate type heat exchanger place is because water temperature is relatively low, can also supply water as workshop and be supplied to workshop use, share a part of workshop refrigeration duty, thus save the energy further;
(3) easy to use, can annually use: when in summer, chilled water storage system of the present utility model can also by regulating the opening and closing of relevant motor-driven valve, first cold-storage loop is disconnected, second cold-storage loop works, thus may be adjusted to traditional chilled water storage system, and then carry out cold-storage, let cool or refrigerator direct-furnish mode operation.
