Abstract

A compact air conditioner with high humidification efficiency and high saturation efficiency is obtained.
SOLUTION: A plurality of heat exchange coils (4) (4) are provided in an air passage (2) in a casing (1) so that air outlet surfaces (3) and (3) face each other. The plurality of heat exchange coils (4) and (4) are arranged so that the distance between the facing air outlet surfaces (3) and (3) is narrow on the windward side in the blowing direction and wide on the leeward side. The air outlet surfaces (3) and (3) are configured to emit humidifying steam on the windward side where the interval is narrow.

Description

  The present invention relates to an air conditioner.

  There is an air conditioner in which the air outlet surface of the heat exchange coil is arranged orthogonal to the air passage in the casing, and a steam humidifier is provided on the leeward side of the heat exchange coil.

JP 2005-283036 A

  However, since the vapor humidifier has a long evaporation absorption distance, an extra space is required for humidification, and the size of the airframe cannot be increased.

  In order to solve the above problems, the present invention provides a plurality of heat exchange coils in the air passage in the casing so that the air outlet surfaces face each other, and the interval between the air outlet surfaces facing each other is on the windward side in the air blowing direction. The main feature is that a plurality of the heat exchange coils are arranged so as to be narrow and wide on the leeward side, and the humidification steam is discharged on the leeward side where the space between the air outlet surfaces is narrow.

  According to the first aspect of the present invention, the air outlet surfaces of the plurality of heat exchange coils are arranged to face each other with the air outlet surfaces being inclined, thereby reducing the coil installation space and the direction of the air passage between the heat exchange coils. This makes it possible to increase the evaporation and absorption distance of steam humidification. Therefore, the humidification efficiency is good, the saturation efficiency can be increased, the humidity control range is expanded, the comfort is improved, and the aircraft can be prevented from being enlarged.

  1 and 2 show an embodiment of an air conditioner according to the present invention. The air conditioner has a fan 1, a fan 5, a heat exchange coil 4, and a steam humidifier in a casing 1. The nozzle 6 and other various devices not shown are provided. The casing 1 is provided with an air inlet 7 and an air outlet 8, and is connected to the air passage 2 in communication.

  The air inlet 7 and the air outlet 8 are communicated with an indoor air-conditioned space, outdoors, or the like by a blower duct or the like. The air is blown in the blower 5 in the direction indicated by the white arrow, and passes through the heat exchange coil 4 to exchange heat. The heat exchange coil 4 is formed by inserting heat transfer tubes into a large number of heat transfer plates provided so as to be freely ventilated, and heat medium and refrigerant flowing through the heat transfer tubes and passing air are heated through the heat transfer tubes and the heat transfer plates. Exchange.

  The air passage 2 in the casing 1 is provided with a plurality of heat exchange coils 4, 4 so that the air outlet surfaces 3, 3 face each other. The plurality of heat exchange coils 4 and 4 are arranged so as to be narrow and wide on the leeward side, and the humidification steam is discharged on the windward side where the space between the air outlet surfaces 3 and 3 is narrow.

  In the illustrated example, only the humidifying nozzle 6 that discharges steam is illustrated as being disposed between the air outlet surfaces 3 and 3 on the leeward side where the interval is narrow, but between the air outlet surfaces 3 and 3 on the leeward side. A device such as a steam generator for supplying steam to the humidifying nozzle 6 may be provided using a wide space.

  In addition, this invention is not limited to the above-mentioned Example, A design change is free in the range which does not deviate from the summary of this invention, and it changes into various things, such as a well-known electrode type, an electrothermal type, and a steam spray type as a steam type humidifier. Be free. Moreover, although the case where there are only two heat exchange coils 4 is illustrated, it is free to divide one or both heat exchange coils 4 to increase the number.

It is a top view of the air conditioner of this invention. It is the perspective view which fractured | ruptured a part of casing and showed the inside.
