Abstract
The utility model discloses a TBAB hydrate cold -storage air conditioning system, this system are divided by cold -storage groove, refrigerating unit, cooling groove and the user four bibliographic categories and form. The outside condenser cooling through refrigerating unit in this air conditioning system's characterized in that cold -storage groove, cold -storage groove are passed through slurry transportation pump and backwash pump and are connected cooling groove and user connection with the cooling groove. This air conditioning system adopts TBAB hydrate thick liquid as cold storage medium, provides cold volume through refrigerating unit and prepares the hydrate thick liquid, and the hydrate thick liquid is stored at the cooling inslot, and the cooling groove provides cold volume through the circulating water to each user. This system compares general cold -storage air conditioner, and it is big to have cold -storage density, easy operation, advantage such as mobile good.
Description
Technical field
The utility model relates to a kind of chilling air conditioning system, particularly relates to the chilling air conditioning system that a kind of cool storage medium is TBAB hydrate slurry.
Background technology
Along with the raising of air-conditioning popularity rate, its electric load consumed also increases at social total electricity load proportion thereupon, becomes the influence factor causing electrical network " peak valley " difference constantly to increase to a certain extent.Cool storage air conditioning technology is the cold be stored at electric low ebb peak in cool storage medium, discharges when peak of power consumption, thus reaches the object reducing electrical network air conditioning electricity peak period load, is to carry out peak load shifting one of economy and effective mode the most to power load.
Chilling air conditioning system is divided into sensible heat cold-storage and latent heat cold-storage.At present, sensible heat cold-storage is mainly water cold storage, and cold-storage water can mate with conventional air-conditioning chilled water, but water cold storage storage density of cold is low, floor space large, limits its scope of application; Latent heat cold-storage is mainly ice conserve cold, and it has the high advantage of storage density of cold, but process of cool need be carried out under cryogenic, causes the coefficient of performance of unit to reduce.TBAB (being called for short TBAB) hydrate is a kind of hydrate of half cage structure, the temperature range of 0-12 DEG C is interior is at ambient pressure formed, relative to the water that phase transformation setting temperature is 0 DEG C, the TBAB aqueous solution is more suitable for the phase-change material as chilling air conditioning system.Half envelope hydrate crystal particulate can be formed with water molecules at normal temperatures and pressures, and be suspended in equably in solution, form TBAB hydrate slurry.This hydrate slurry not only has good mobility, can transport in the duct, and its liquid-solid-phase changeable process is reversible, is attended by a large amount of latent heats of phase change.
Summary of the invention
The novel hydrates chilling air conditioning system that the object of the utility model patent is to provide a kind of chilling air conditioning system to realize storage density of cold is high, run at normal temperatures and pressures.Based on above-mentioned purpose, the utility model takes following technical scheme:
A kind of TBAB hydrate chilling air conditioning system, comprises cold-storage groove, for cold trap, refrigeration unit, user four part; Described cold-storage groove upper end is provided with inlet, and lower end is provided with slurries delivery port; Be provided with for slurry mouth for cold trap upper end, lower end is provided with refluxing opening; Slurries delivery port is by slurry feeding pump and being connected for starching mouth for cold trap upper end, and centre arranges valve A; Refluxing opening for cold trap lower end is connected by the inlet of reflux pump with cold-storage groove upper end, and centre is provided with valve B.
The TBAB mass fraction being filled with 0.5 ~ 0.6 volume in described cold-storage groove is the aqueous solution of 30% ~ 45%.
Cold-storage groove outside is provided with the condenser being connected with refrigeration unit.
Coil heat exchanger is provided with for cold trap inside.
Be connected by inner disk heat exchange of heat pipe with user for cold trap.
The beneficial effects of the utility model are:
1.TBAB hydrate slurry preparation can at ambient pressure 0 DEG C-10 DEG C carry out;
2.TBAB hydrate slurry latent heat of phase change is large, and good fluidity, not easily blocking pipe;
3., for the system of the inner heat release of cold trap, the outside cold-storage of cold-storage groove, heat exchange efficiency is higher.
Accompanying drawing explanation
Fig. 1 is TBAB hydrate chilling air conditioning system flow chart;
Figure number illustrates:
1-condenser, 2-cold-storage groove, 3-inlet, 4-slurries delivery port, 5-reflux pump, 6-refrigeration unit, 7-slurry feeding pump,
8-is for slurry mouth, and 9-refluxing opening, 10-supplies cold trap, 11-user, 12-valve A, 13-valve B, 14-valve 1,15-valve 2,16-valve 3,17-valve 4.
Detailed description of the invention
The utility model is set forth further below in conjunction with Fig. 1.
A kind of TBAB hydrate chilling air conditioning system, comprises cold-storage groove 2, for cold trap 10, refrigeration unit 6 and user 11 4 part.First at the TBAB aqueous solution of cold-storage groove 2 built with 1/2-2/3 volume, need during cold-storage, to open refrigeration unit 6 pairs of cold-storage grooves 2 and be cooled to 0-10 DEG C, then TBAB generates hydrate slurry under appropriate conditions, then opening slurry feeding pump 7 is delivered to for storage in cold trap 10 by the TBAB hydrate slurry of generation, when cold carried by needs to user, open valve 1, valve 2, valve 3, valve 4, the circulating water temperature of user 11 end is higher, when passing through for cold trap 10 inner disk heat exchange of heat pipe, because TBAB hydrate slurry divides heat of desorption, thus reach the object of cooling, after TBAB hydrate slurry decomposes completely, open reflux pump 5, the TBAB aqueous solution is delivered in cold-storage groove 2 and recycles, the TBAB hydrate slurry cold-storage adopted in this system, compares other media and has the advantages such as storage density of cold is high, good fluidity.
