Shanghai China department of mechanical engineering of Tongji University but do not see the series of products of sweat cooling air-conditioner as yet.

The purpose of this utility model is to propose a kind ofly can to utilize natural advantages such as dry hot climate and ground water temperature are low, can satisfy the refrigeration air-conditioner requirement, can save investment, the saving energy, the series of products of the sweat cooling whole fresh wind air-condition device of streamlining management again.

Design philosophy principle of the present utility model based on, the liquid water surface is easy to evaporation under arid and hot environment, and liquid, the gas phase of liquid water when evaporation becomes, need heat to provide phase transformation necessary gasification latent heat, this part heat is provided by heated dry air, after the heat that heated dry air carries is converted into the gasification latent heat of liquid water, promptly realize the purpose of refrigeration.

The technological difficulties that need to solve are: how enlarge the heat of core body, wet conversion face in the limited spatial volume of core body as far as possible; How continuously, make equably on the core body sheet surface area and spread all over moisture film; How to make the uniform moisture film of a side surface of the arbitrary core body sheet in the core body, and the heated dry air of opposite side surface by being cooled, and make its cooling refrigeration; How farthest to reduce the flowing resistance of core body; How to improve the hydrophily of core body sheet material; How to select suitable core body sheet material and structure thereof for use.

For this reason, the key of implementer's case of sweat cooling whole fresh wind air-condition device of the present utility model is the core body design of this air-conditioner and the research of processing technology thereof, in should the core body in certain volume, design the large tracts of land and the core body sheet of multi-disc number as far as possible as far as possible, increase heat, wet exchange area and show cold exchange area with this.Thereby realize the purpose of refrigeration air-conditioner.

According to design principle, sweat cooling air-conditioner of the present utility model has two kinds of specific embodiments, and a kind of is that moisture film is all covered directly and the direct-type sweat cooling whole fresh wind air-condition device of outdoor high temperature air contact heat-exchanging in the two sides of core body sheet monolithic; Another kind is that the fresh air that is cooled is flow through in a side of core body sheet, the another side trickle, and the moisture film of trickle side surface absorbs the heat of the air that is cooled, and is carried outside by secondary wind with the steam form, drains into the indirect type sweat cooling air-conditioner of atmosphere.

According to using needs, direct-type sweat cooling air-conditioner (ZZK type) can be divided into cross-flow type 1 type, (ZZK-H-1 type), cross-flow type 2 types (ZZK-H-2 type) and reverse-flow 1 type (ZZK-N-1 type), reverse-flow 2 types (ZZK-N-2 type).Indirect type sweat cooling air-conditioner (JZK type) can be divided into the JZK-1 type, the JZK-2 type; Direct-type and indirect type sweat cooling air-conditioner be capable of being combined again to become the JZZK type, this combined JZZK type air-conditioner has following serial model No. with the size of its air output: JZZK-10 type (being the combination of JZK-10 type and ZZK-10 type), JZZK-40 type, JZZK-60 type, JZZK-90 type, JZZK-100 type, JZZK-120 type, JZZK-150 type, JZZK-200 type, JZZK-250 type, JZZK-300 type, JZZK-350 type, JZZK-400 type, JZZK-450 type, JZZK-500 type, JZZK-600 type, JZZK-800 type.
