Abstract

PURPOSE:To freely supply cool-air or hot-air at a flow rate required for an underfloor space and diminish vibration noise due to air flowing through an air inlet into the underfloor space by a method wherein an air duct consisting of upper, middle and lower parts is formed into a Z-shape or U-shape, and an air outlet located at the lower part of an apparatus is communicated to a lower air duct in which a silencer is provided. CONSTITUTION:The inside of an apparatus 1 is divided by partition plates so as to form a Z-shaped air duct, and an air outlet 4 provided at the lower part of the apparatus 1 is located in the space under a floor or on the floor surface. A damper mounted in an outside air intake 2 is operated so as to introduce the outside air into the apparatus 1 during operation. The outside air introduced passes through an upper duct A and flows toward a middle air duct B after heat-exchanged at an outside air heat exchanging coil 5 to raise it to a required temperature. On the other hand, the room air recycled from a room air suction port 3 is mixed with the outside air, heat-exchanged and humidified at a main heat exchanging coil 8, blown from the air outlet 4 located at the lower part of the apparatus 1 into an underfloor space X via a lower air duet C by a fan 9 to perform underfloor cooling or heating.

支障である等重大なる欠点を有していたのである。In recent years, various types of air-conditioning equipment for floor surfaces have been developed as a means of solving the above problem. This is completely impossible with these devices, and especially when using these devices, the air discharge sound naturally flows out along with the wind flow from the ventilation openings under the floor, causing noise and noise, which is extremely troublesome. It had serious drawbacks.

Each opening is provided with a ventilation opening in the underfloor part of the lower part of the fuselage, and a part ventilation passage A is provided inside the fuselage which communicates with the above-mentioned outside air intake and indoor air intake, and a middle ventilation passage B is provided below the passage.
Below that, a Z-shaped ventilation passage consisting of a lower ventilation passage C communicating with the ventilation opening is formed, and an upper ventilation passage A is formed.
Inside, an outside air processing heat exchange coil is installed horizontally diagonally, and in the middle ventilation passage B, a pre-main filter and main heat exchange coil are installed diagonally, and mechanisms such as a blower, electric motor, humidifier, drain pan, etc. It is characterized by a structure in which a silencing mechanism is integrally disposed within the ventilation passageway C at the bottom.

On the other hand, the indoor air returned from the indoor air inlet is mixed with the outside air, heat exchanged and humidified to an appropriate temperature in the main heat exchange coil, and then sent through the lower air passage C by the blower to the air outlet at the bottom of the fuselage. This makes it easier to blow air into the underfloor space X to perform underfloor cooling and heating.
