Description
Technical field
The invention belongs to operation of air conditioning systems technical field, be specifically related to a kind of dew point indirect evaporative cooler of improved form, adopt the cooler form that adverse current is board-like.
Background technology
Indirect evaporation cooler is current a kind of novel operation of air conditioning systems.It utilizes the difference of dry-bulb temperature in natural environment air and wet-bulb temperature, obtains a kind of environment-friendly high-efficiency of Psychrometric Energy and the type of cooling of economy by the hot and humid area between water and air.When not using compressor and cold-producing medium, can refrigerating gas to the wet-bulb temperature approaching air, and do not increase the water capacity of output air.Evaporative cooling process can adopt all-fresh air, and air quality is good.
Dew point indirect evaporative cooler, as the improvement to indirect evaporative cooling technology, can realize multistage influence diagram cooling.It utilizes the auxiliary air wet-bulb temperature constantly reduced to promote hot and humid area, and the temperature of air to be cooled is reduced to the wet-bulb temperature lower than intake air, even reaches dew-point temperature, lower than traditional indirect evaporative cooling technology.
Dew point indirect evaporative cooler is made up of the dry passage of uniform spaced arrangement and wet channel.Cooled air, as primary air, flows in dry passage.By the baffle plate between dry passage and wet channel, a part of primary air flows in wet channel plate, flows together with the original air in wet channel as auxiliary air in wet channel.Constantly have Water spray in wet channel, auxiliary air directly contact with water, blending, carry out hot and humid area, then separate separately.In wet channel, cooled auxiliary air absorbs heat in dry passage, and primary air etc. are but clammy.Along with the air themperature flowing into wet side constantly reduces, primary air obtains sensible heat cooling further.So go down, until primary air by etc. below the wet wet-bulb temperature being cooled to entrance state and close to its dew-point temperature, and keep humidity constant.After auxiliary air absorbs heat, from wet channel discharge chamber.
At present, conventional cooler construction mainly contains tubular type and board-like.Compared to chimney cooler, it is high that plate-type evaporative cooler has heat transfer efficiency, and resistance is relatively little, compact conformation, dismounting easy to clean, and heat-transfer area can change and the advantage such as combination flexibly.
The flow direction of primary air and auxiliary air, the flow direction of auxiliary air and water, the cooling effectiveness for cooler plays a major role, and also determines the degree of primary air cooling.Experimental and theoretical computation all confirms, when identical out temperature, when primary air and auxiliary air, auxiliary air and shower water adverse current, the relatively mild and mean temperature difference of two fluid temperature differences changes greatly, more be conducive to heat exchange, therefore countercurrent flow is the most efficient a kind of methods for cooling, and can save certain space.But, due to the difficulty that evaporative cooling system is arranged, the type of flow many employings cross-flow before.
In addition, the selection for channel partition material is also the key factor affecting cooler performance.In wet channel, in auxiliary air, recirculated water and dry passage, primary air flows respectively in respective runner, interchannel is separated by channel partition, fluid does not contact each other, heat is delivered to auxiliary air by channel partition from primary air, complete cooling procedure, therefore need channel partition to have comparatively good heat conductive performance, and one side hydrophilic (wet channel side) one side hydrophobic (dry passage side), be convenient to shower water attachment, strengthen and exchange with the caloic of auxiliary air.Channel partition material conventional mostly at present is aluminium foil, plastics, fibre sheet material or composite.The performance of homogenous material is single, and can not have the hydrophobic and condition that deflection is enough of the hydrophilic one side of one side, composite sheet is subject to the impact of combination process, and hydrophilic effect is bad simultaneously, and channel partition is thicker is unfavorable for heat exchange, therefore needs more preferably alternative materials.
Summary of the invention
For prior art Problems existing, the invention provides a kind of board-like dew point indirect evaporative cooler of adverse current of built-in flow dividing structure, the present invention to make in dry passage in primary air and wet channel auxiliary air and shower water body normal direction in cooler in auxiliary air, wet channel realize countercurrent flow, increase heat transfer temperature difference, improve heat and mass driven potential, improve the cooling effectiveness of cooler, and cooler internal resistance can be reduced.Meanwhile, the channel partition of the cooler core in the present invention adopts plastics as base material, and utilize planar electrostatic flocking technique to carry out flocking to the one side of base material, improve the volatility after water suction and heat conductivility, thus whole board-like dew point indirect evaporative cooler heat exchange property is promoted.
