Description
Technical field
The utility model relates to central air-conditioning chilled water storage system.
Background technology
Central air-conditioning is the part of modern society's demand.Its energy consumption occupies significant proportion in social energy consumption.In summer, the maximum load of the whole society of China electric load generally appears at 10:00 ~ 12:00, and from 21:00, electric load declines gradually, reaches minimum to about 06:00.The core content of central air-conditioning Cool Storage Technology is exactly " peak load shifting ", namely when power load is low, runs central air conditioner main machine and cold is stored, and when electricity consumption high load capacity, central air conditioner main machine of stopping using, meets cooling needs with the cold release stored.
Like this, electrical network pressure when just can reduce high load capacity, the electricity charge more cheap when simultaneously utilizing electrical network underload.This just can reduce power plant and build more multiple generator in order to the high load capacity of short time.Reduce electric grid investment, grid equipment utilization rate improves.
Cold storage capacity follows heat formula:
Q=CMΔT
Q---cold storage capacity
The specific heat capacity of C---cool storage medium, constant
The quality of M---cool storage medium
Δ T---store temperature difference when letting cool
According to above-mentioned heat formula, identical cold storage capacity, stores the temperature difference let cool larger, and the quality requirement of cool storage medium is less.In other words, the cool storage medium of equal in quality, stores the temperature difference let cool larger, and the cold that can store is more.
One, ice-storage system is one of cold accumulation system conventional at present, and its operation characteristic is:
During paddy electricity, main frame runs ice making operating mode, water is made the ice of subzero 5 DEG C, is stored in ice bank; During ordinary telegram, main frame running refrigerating operating mode, for end directly provides the low-temperature receiver of 7 DEG C; During peak electricity, before the cold of ice bank discharges and terminates, main frame is out of service, and ice bank is end cooling as low-temperature receiver.
Liquid stores for ice by the process of ice conserve cold, belongs to phase transition process.The cold store, put is large compared with simple liquid cold-storage; The occupation of land of ice bank is less.But the ice making main frame different from normal hosts (normal hosts can not run to-5 DEG C) that Xu Yuanzhong needs, in transformation project, needs newly-increased ice-reserving main frame.Ice conserve cold main frame due to be not be operated in common refrigeration host computer operating mode under.About 30% to be declined relative to normal hosts operating efficiency.This reduces the effect of the real saving electric energy of ice conserve cold, even occur the result lost more than gain, simultaneously because system complex cost is higher.
Two, chilled water storage system is another kind of cold accumulation system conventional at present, and its operation characteristic is:
During paddy electricity, the leaving water temperature of main frame is generally set to 4 DEG C (some projects are different), carries out cold-storage, by the water for cooling to 4 in cold accumulating pond DEG C; During ordinary telegram, main frame running refrigerating operating mode, for end directly provides the low-temperature receiver of 7 DEG C; During peak electricity, main frame is out of service, and cold accumulating pond is separately end cooling as low-temperature receiver.
The cold-storage temperature of water cold storage is generally 4 DEG C, compared with 7 DEG C that meet end needs, only has 3 DEG C of temperature difference, and compared with ice conserve cold, the cold-storage device volume that identical cold storage capacity needs is larger; The process of water cold storage is exactly simply reduce water temperature when night, power load was low by central air conditioner main machine in fact, has the advantages such as practical simple.But due to the water tank that the very little needs of the cold-storage temperature difference are huge especially.Area occupied is too large.Invest also high, a lot of place cannot be implemented because place limits project.Need complicated water distribution system simultaneously.
