Description
Technical field
The invention belongs to energy technology field, relate in particular to a kind of method of horizontally multistage indirect evaporation cooling refrigeration of the technology of transpiration-cooled cooling.
Background technology
Different according to carrying cold medium, the evaporation cooling technique mode that mainly is divided three classes: the one, the mode of preparation cold wind; The 2nd, the mode of preparation cold water; The 3rd, prepare the mode of cold water and cold wind simultaneously.
The mode of utilizing evaporative cooling to prepare cold wind develops early; Improvement along with flow process and technology; Difference according to the weather conditions of different regions; The evaporative cooling that exists at present extensively prepares the method for cold wind, mainly comprise single-stage direct evaporative cooler, single-stage indirect evaporation cooler, multi-stage indirect evaporative cooler and multistage directly, the devaporizer that combines of indirect evaporation cooling.With three grades of devaporizers that directly, combine indirectly is example; Wherein preceding two-stage is an indirect evaporation cooler; And afterbody is a direct evaporative cooler; For preceding two-stage indirect evaporation cooler, the auxiliary air source of carrying out direct evaporative cooling process according to its inside is different, and the effect of indirect evaporation cooling is just different.Present most indirect evaporation cooler is normal to adopt outdoor wind as auxiliary air; A part that perhaps adopts the primary air air intake is as auxiliary air; This situation air only can be cooled to the wet-bulb temperature of outdoor wind or a wind, thereby limited the effect that evaporative cooling prepares cold wind.Prior art adopts the part of primary air air-out as auxiliary air, and the limiting temperature that makes primary air be cooled can reach the dew-point temperature of air intake; And the technology one of adopting said method is the mode that direct evaporative cooling of single-stage and aerial cooler combine at present; This mode can't solve the non-linear geomantic omen that causes of saturated line and compare mismatch problem; And, the single-stage mode improves the be cooled words of efficient of air if pursuing adverse current; Only can design reflux type, make that unit is vertical, the unit application scenario is limited; And existing technology is through changing technology; The mode of cold module realizes reverse-flow indirect evaporation cooling procedure in the employing; In cold mode effect better; But with external-cooling type-directly evaporative cooling is compared with the mode that aerial cooler combines, the technological requirement of inner-cooled is higher, and the difficulty of research and development and the popularization of scale property is bigger.
Popularization along with evaporation cooling technique comfort air conditioning system in large public building; The mode that tradition utilizes evaporative cooling to prepare cold wind is showed drawback gradually: the system that evaporative cooling prepares cold wind only can be used for all-air system; The air channel takes up room greatly; The blower fan power consumption is high, thus than limitations the application scenario of evaporation cooling technique.And then, the mode of indirect evaporation cooling preparation cold water (a kind of method of indirectly evaporating cold supply and device thereof: invention ZL02100431.5), opened up the frontier that evaporation cooling technique is used.Based on successful the carrying out of this technology the research and development and the engineering practice of indirect evaporation cooling-water machine, at present in more than ten large public building of Xinjiang region by being applied, utilize the technology of indirect evaporation cooling preparation cold water tentatively to obtain success.Yet; Indirect evaporation cooling-water machine based on above-mentioned technical research is mainly vertical reverse-flow structure at present; Unit self can't solve the non-linear mismatch problem that causes of saturated line, and unit is higher, suitable being applied in the large-scale large public building; And when being applied to build on a small scale, the installing space of unit is restricted.Can change vertical indirect evaporation cooling-water machine into horizontal unit, become the key of further expansion indirect evaporation cooling-water machine application scenario.
When the indirect evaporation cooling-water machine only was used for taking away the room sensible heat, because the restriction of heat source temperature level, the air draft parameter of indirect evaporation cooling-water machine was limited in reduced levels, thereby had limited the efficient that unit utilizes dry air to freeze.For addressing this problem; The nonlinear problem of flow matches, saturated line, the while of investigating evaporative cooling process and sensible heat transfer process simultaneously tentatively become unit horizontal; A kind of indirect evaporation refrigerating method (China for preparing cold water and cold wind simultaneously; 200810103448.0) invention, utilize the indirect evaporation refrigerating mode to prepare simultaneously and take away the new wind of room sensible heat with the required low temperature of cold water and room.In the method; The method that a kind of multistage evaporation heat of cooling reclaims has at first been proposed; As shown in Figure 5; The method by multistage direct evaporative cooling module and with it one to one the multi-stage countercurrent aerial cooler combine; Between every grade of direct evaporative cooling module and counter-flow air cooler, form independently cold water circulation, prepare the air intake that cold water cools off the counter-flow air cooler through direct evaporative cooling module, thus the multistage full heat recycle process between the air intake of the air intake of realization aerial cooler and direct evaporative cooling module.This indirect evaporation refrigerating method for preparing cold water and cold wind has simultaneously tentatively solved problems such as the indirect evaporation cooling-water machine vertically takes up space, the air draft parameter is low, the non-linear geomantic omen ratio that causes of saturated line does not match, and has tentatively enlarged the application space of indirect evaporation cooling-water machine.Yet the single-stage mode that remains that the module of preparation cold water adopts in the method is when cold water side supplies, when backwater temperature difference is higher, in the module of the preparation cold water of distributary single-stage, because the leaving water temperature of module diverse location is inhomogeneous, makes bigger mixed water loss; And because whole distributary guarantees the heat and mass transfer performance between air-water and guarantees that the efficient that cold water is lowered the temperature requires also inconsistent to the ratio of the geomantic omen between the empty G&W; Can the equipment that these problems often become adopting said method under the actual condition efficiently realize preparing the key of cold.
Thus; Problem that comprehensive above-mentioned three types of evaporating and cooling methods exist and the present situation of dealing with problems at present; The present invention proposes a kind of method of multistage indirect evaporation cooling refrigeration, be utilized in evaporation cooling technique prepare separately cold wind, separately prepare cold water, simultaneously prepare cold water and cold wind with one the cover horizontal multi-stage evaporating and cooling method realize; Mode through horizontal multi-stage makes the type of flow between air-water near adverse current, guarantees the requirement of heat and mass between air-water of every grade simultaneously; And the mode through horizontal multi-stage makes evaporative cooling prepare the non-linear mismatch problem that causes of the process solution saturated line of cold water; Direct evaporative cooling module and the mode of aerial cooler combination of the method for this horizontal multi-stage through external-cooling type realizes, makes technology simple relatively, the potentiality of applying with have a extensive future; Owing to adopt the sweat cooling mode of horizontal multi-stage, utilize the device height of the method to reduce, thereby the dispersed building on a small scale that is applied to preferably is further practiced thrift the transmission & distribution power consumption; According to the demands of different of different occasions, can select to produce separately the cold wind mode, separately produce the cold water mode, prepare the mode of cold water and cold wind simultaneously, improve application flexibility, thereby make that evaporation cold-zone The Application of Technology occasion is more extensive.
Evaporation cooling technique is a mode of utilizing outdoor natural dry air to freeze, because its drive energy no longer is an electric energy, and relative traditional mechanical compression-type refrigeration mode energy-conservation 40%～70%; And it does not use CFCs, and is pollution-free to atmosphere, becomes the mode of utilizing of clean reproducible energy-outdoor dry air resource, has a extensive future.
