Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in more detail.
See Fig. 1-Fig. 4, upper as can be seen from figure, the present invention a kind ofly comprises air heat-exchanging device 1 for the low energy consumption cooling-dehumidifying air device based on phase-change material for cold storage in enclosure space, and air heat-exchanging device 1 lower end taps into wind apparatus 2, and upper end picks out wind apparatus 3.Described air heat-exchanging device 1 is the rounded cylindrical body of hollow, is provided with the air channel 4 of some up/down perforations in cylindrical body.During actual design, described air channel 4 is formed through air heat-exchanging device by some tube banks.Be provided with at cylindrical body upper surface and add ice hole 5 for adding ice material around the inner air channel of cylindrical body, add ice hole 5 and be provided with openable sealing mechanism (seal cover) to be closed in cylindrical body by ice material, cylindrical body lower end is with leakage fluid dram 6 to discharge the ice material after thawing, and leakage fluid dram is provided with openable sealing mechanism equally.Described air-intake device 2 is with uniform flow chamber and the air inlet 7 be communicated with uniform flow chamber and condensation-water drain 8, and one end, all air channels is communicated with uniform flow chamber.Described exhaust apparatus 3 is provided with air collecting box 9, and all air channels other end is communicated with air collecting box 9, and air collecting box 9 closes up and forms air outlet 10, is provided with pressure fan 11 in air outlet 10.The equal isothermal holding in all cold bridge positions of air heat-exchanging device or be insulation material.
When this device uses, first in tubular air processor, add ice material (as ethylene glycol compound ice hockey mixture, but be not limited to this), then pressure fan is started, at pressure fan suction side, negative relative is formed in the air channel of air-intake device inside and air heat-exchanging device, in enclosure space, Hot wet air heating enters uniform flow chamber via the air inlet of air-intake device, evenly enter each air channel again, heat exchange is carried out with the ice material in cylindrical air treating apparatus in air channel, the cooled dehumidifying of Hot wet air heating, condensed water falls in air-intake device uniform flow chamber along air channel under gravity (or microgravity) effect, get rid of finally by condensation-water drain.Air after process enters in exhaust apparatus air collecting box, flows out, enter enclosure space after pressure fan pressurization from air outlet.Solid ice material undergoes phase transition after absorbing latent heat gradually, until all melt as liquid, then liquid continues to absorb sensible heat and constantly heats up, when fluid temperature reaches a certain preset temperature, think that its cooling and dehumidifying ability can not reach expection requirement, so open sealing mechanism, liquid is emptying via cylindrical body lower end leakage fluid dram, again leakage fluid dram is closed after emptying, then ready ice material is added by adding ice hole, to add ice hole again to close, device recovers initial heat and wet treatment ability, continues the cooling and dehumidifying process starting a new round.
Preferably, the air inlet of described air-intake device is arranged on the sidewall of uniform flow chamber, and condensation-water drain is located at bottom uniform flow chamber.Condensation-water drain is sealed by sealing device, and prescribe a time limit when condensation water quantity reaches the upper of liquid collector capacity, condensed water concentrates other purposes of discharging for this enclosure space.
The air inlet of described air-intake device is adjustable louver structure, is carried out the return air amount of adjusting device by the angle of adjusting louver structure, to control air supply parameter, reaches the object regulating temperature in enclosure space.
In the laying in air channel, air channel on air heat-exchanging device of the present invention is positioned evenly on multiple concentric circles, and be positioned on equally distributed multiple radius simultaneously, see Fig. 4, to reach the ice homogenize material heat exchange in air and cylindrical air treating apparatus, avoid because local undergoes phase transition fast and cause cylindrical air treating apparatus internal heat, and then the phenomenon that device exchange capability of heat is declined occurs.
The usual vertical display of cooling and dehumidifying device of the present invention with under facilitating condensation flow, if need to tilt also can, as long as ensure that condensed water can flow out from condensation-water drain along air-intake device below gravity or microgravity direction flow into.
Store up icy material (below for ethylene glycol ice) cold-storage and belong to phase change cold-storage technology, utilize the phase transition process of ethylene glycol solution to carry out storage and the release of latent heat, there is the advantages such as storage density of cold is large, cold-storage temperature constant.The present invention utilizes ethylene glycol ice storage technology, carries out cooling and dehumidifying process to the air in enclosure space (as flight capsule, refuge cabin etc.).Carried out the high density storage of phase transformation cold by the ethylene glycol compound ice hockey mixture made outside enclosure space in advance, be then transferred in enclosure space and carry out the release of controlled, lasting cold.Whole system forms simple, without the need to external low-temperature receiver and heat sink, nothing refrigeration moving component, without potential safety hazard, efficiently solve the difficulties of low-temperature receiver source in enclosure space, heat sink place to go, refrigeration power, equipment quality and many enclosure space air conditionings such as volume, operation maintenance.
The present invention makes full use of ice material Cool Storage Technology, refrigeration problem in enclosure space is transferred to the external process of enclosure space, refrigeration problem during carrying out in enclosure space is transferred to before carrying out and processes, achieve the Time-spatial diversion of technological difficulties dexterously, drastically increase the efficiency of air-treatment in enclosure space, save manufacture and operation expense, embody the spirit of philosophy of engineering.
The present invention carries out refrigerated dehumidification without the need to consuming additional energy, and low-temperature receiver is supplied by cold-storage ice material, and system only exists fan energy consumption.This for requiring that weight is low, the simple and safe airtight little space such as flight capsule, refuge cabin of less energy consumption, control carries out the environmental Kuznets Curves demand of certain hour, possesses larger Practical significance.
Finally it should be noted that, above embodiment is only in order to illustrate technical scheme of the present invention and unrestricted, although applicant's reference preferred embodiment is to invention has been detailed description, those of ordinary skill in the art is to be understood that, technical scheme of the present invention is modified or equivalent replacement, and do not depart from aim and the scope of the technical program, all should be encompassed in the middle of right of the present invention.
