Desiccant air conditioning device

Abstract

Provided is a desiccant air conditioning device which has a simple structure and makes it possible for the dehumidifying capability of a desiccant rotor to be effectively exhibited. A desiccant air conditioning device (1) comprises: an inlet passage (11) which introduces air (SA) from an outdoor area to an indoor area; an outlet passage (12) which discharges air (RA) from the indoor area to the outdoor area; a desiccant rotor (2) which dehumidifies the air (SA) flowing through the inlet passage (11) by absorbing moisture from the air (SA), and also restores dehumidifying capability by releasing moisture into the air (RA) flowing through the outlet passage (12); a heating heat exchanger (3) which heats the air (RA) of the outlet passage (12); a sensible heat exchanger (4) which performs heat exchange between the air (SA) flowing through the inlet passage (11) and the air (RA) flowing through the outlet passage (12). A first humidity control region (2a), a second humidity control region (2b), a first restoration region (2c), and a second restoration region (2d) are alternately formed in the desiccant rotor (2). The air (SA) of the inlet passage (11) flows through the first and second humidity control regions (2a, 2b), and the air (RA) of the outlet passage (12) flows through the first and second restoration regions (2c, 2d).

Description

technical field [0001] The present invention relates to a dehumidification air conditioning device using dehumidification or humidification and sensible heat exchange. Background technique [0002] Because the dehumidification air conditioner is different from the refrigeration dehumidification method, it first dehumidifies the air and then cools the air, so there will be no mold or bacteria breeding, and the dehumidification air conditioner does not need to use Freon. Therefore, the dehumidification air conditioner is used as the future air conditioner. attention. [0003] Figure 9 The structure of a typical desiccant air conditioner a is shown. That is, the desiccant air conditioner a is constructed by arranging the introduction duct b allowing the air SA from the outside to flow into the room and the discharge duct c allowing the air RA from the room to flow to the outside in an adjacent convective state so that the air SA and RA flow in the opposite direction, and the...

AI Technical Summary

Problems solved by technology

[0005] This desiccant air conditioner a is limited in its ability to control humidity or temperature because the dehumidification capacity depends on the performance of the desiccant rotor d

In particular, since the desiccant rotor d generates hygroscopic heat when absorbing moisture into the air SA passing through the introduction pipe b, the moisture absorption capacity deteriorates, and the improvement of the dryness is also limited.
