Description
Technical field
The present invention 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.Summer,
The maximum load of the whole society of China electric load is generally present in 10:00~12:00, from 21:00 beginning electric load is gradually reduced, extremely
06:00 or so reaches minimum.The core content of central air-conditioning Cool Storage Technology is exactly " peak load shifting ", i.e., when power load is low,
Run central air conditioner main machine cold is stored, in electricity consumption high load capacity, disable central air conditioner main machine, expired with the cold release of storage
Sufficient cooling needs.
In this manner it is possible to power grid pressure when reducing high load capacity while the relatively inexpensive electricity charge of using power grid underload when.This
More multiple generator is built in a power plant that can reduce for the high load capacity of short time.Reduce electric grid investment, grid equipment profit
Improved with rate.
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 that the temperature difference let cool is bigger, and the quality requirement of cool storage medium is got over
It is small.In other words, the cool storage medium of phase homogenous quantities, stores that the temperature difference let cool is bigger, and the cold that can be stored is more.
First, ice-storage system is one of currently used cold accumulation system, its operation characteristic is：
During paddy electricity, host runs ice making operating mode, and water is made to subzero 5 DEG C of ice, is stored in ice bank；It is main during ordinary telegram
Machine runs cooling condition, and 7 DEG C of low-temperature receiver is directly provided for end；When peak is electric, before the cold release of ice bank terminates, host stops fortune
OK, ice bank is end cooling as low-temperature receiver.
It is ice that the process of ice cold-storage, which stores liquid, belongs to phase transition process.The cold store, put is big compared with simple liquid cold-storage；
The occupation of land of ice bank is smaller.But the ice making host that Xu Yuanzhong needs is different from normal hosts（Normal hosts cannot run to-
5℃）, it is necessary to newly-increased ice-reserving host in transformation project.Ice cold-storage host is not due to being the operating mode for being operated in common refrigeration host computer
Under.To decline 30% or so relative to normal hosts work efficiency.This reduces the effect that ice cold-storage really saves electric energy
Fruit, in addition occur losing more than gain as a result, simultaneously because system complex cost is higher.
2nd, chilled water storage system is currently used another cold accumulation system, its operation characteristic is：
During paddy electricity, the leaving water temperature of host is generally set to 4 DEG C（Some projects are different）, cold-storage is carried out, i.e., by cold-storage
Water in pond is cooled to 4 DEG C；During ordinary telegram, host operation cooling condition, is the low-temperature receiver that end directly provides 7 DEG C；When peak is electric, host stops
Only run, cold accumulating pond is individually for end cooling as low-temperature receiver.
The cold-storage temperature of water cold storage is usually 4 DEG C, and compared with 7 DEG C that meet end needs, only 3 DEG C of temperature difference, store with ice
Cold-storage device volume bigger cold to compare, that identical cold storage capacity needs；The process of water cold storage is exactly simply to be used at night in fact
Water temperature is reduced by central air conditioner main machine when electric load is low, is had the advantages that practical simple.But since cold-storage temperature difference very little needs
Water tank that will be especially huge.Area occupied is too big.Investment is also high, and many places can not implement due to place limitation project.At the same time
Need the water distribution system of complexity.
The content of the invention
In view of the deficiencies of the prior art, the present invention provides a kind of floor space is small, cost of investment is low, applied widely,
The central air-conditioning chilled water storage system of low-energy-consumption high-efficiency.
The key problem in technology of the present invention is to propose central air-conditioning cold side chilled water storage system, cold-storage different from the past first
The structure that pond terminad is let cool, and the structure let cool using cold accumulating pond to host condensation end.
To realize the object of the invention, there is provided following technical scheme：A kind of central air-conditioning chilled water storage system, including host,
The cooling water circulation pipeline being connected with host and the freezing water-circulation pipe being connected with host, the cooling water circulation pipeline bag

The pipeline of device, the pipeline for connecting water collector, connect and V1 valves are provided with the pipeline of water knockout drum, connect and set on the pipeline of water collector
It is equipped with refrigerating water pump, V3 valves, it is characterised in that further include storage, let cool system, it is described to store, let cool system including cold accumulating pond and store
Cold drop connection charge cycle pipeline and let cool pipeloop, charge cycle pipeline is connected including one end with host, the other end and
The No.1 pipeline of cold accumulating pond connection and one end are connected between refrigerating water pump and V3 valves, be connected with cold accumulating pond No. two of the other end
Pipeline, the No.1 pipeline connect cold-storage heat-exchanger, V2 valves are provided between host and cold-storage heat-exchanger, cold-storage heat-exchanger is with storing
Cold-storage pump and V5 valves are disposed between cold drop, No. two pipelines connect cold-storage heat-exchanger, and refrigerating water pump exchanges heat with cold-storage
V4 valves are provided between device, V6 valves are provided between cold-storage heat-exchanger and cold accumulating pond；It is described let cool pipeloop include one end with
Host connects, and No. three pipelines of other end connection cold accumulating pond, one end are connected between cooling pump and V13 valves, and the other end is with storing
No. four pipelines of cold drop connection, No. three pipelines connection let cool heat exchanger, host and let cool and are provided with V12 valves between heat exchanger

Beneficial effect of the present invention：Host chilled water leaving water temperature during cold-storage is identical with normally freezing, and host remains
Effec-tive Function；
Cold water when letting cool can use 25 DEG C, and compared with 7 when cold-storage DEG C, 18 DEG C of the temperature difference, is significantly higher than light water
3 DEG C of temperature difference of cold-storage.Although 12 DEG C of temperature difference of Temperature Difference Ratio ice cold-storage are big, the phase transition process of ice cold-storage, phase homogenous quantities are considered
Cool storage medium, central air-conditioning cold side water cold storage and the cold storage capacity of ice cold-storage are essentially identical, but cost is lower；Central air-conditioning is cold
But side water cold storage is not high to the temperature requirement of cold-storage water, i.e., of less demanding to the water distribution of cold accumulating pond, and the cost of cold accumulating pond is than common
Water cold storage is lower.
