A discharge unit 90b is mounted below the hopper 85b, and the discharge unit 90b is provided with a diffuser grill 94b formed in four directions of the surface so that the discharged air is obliquely discharged downward. 93b) and the diffuser 93b are rotated by the chain 91b fastened to the diffuser 93b and the motor 92b to transmit rotational force so as to rotate the direction of the air discharged by rotation. Is made of.

Here, in the third embodiment, as shown in FIG. 12, the main body housing 20b may be fixed to an upper side of an inner sidewall of the building, and an inner circulation duct 100b may be connected to both sides of the ceiling, and the inner circulation The duct 100b may have a suction port 101b formed at one end thereof and be connected to a central portion of the ceiling, and an outlet 102b formed at the opposite end thereof may be connected to one upper side of the main body housing 20b.

Referring to the operation method according to a third embodiment of the present invention configured as described above are as follows.

8 is an operational state diagram illustrating a process of introducing indoor air and discharging it down in the third embodiment of the ceiling type convection circulation heat exchange air conditioner according to the present invention.

Referring to Figure 8, first the air in the building is installed inside the building, but begins to flow into the upper side of the main body housing 20b fixed to the ceiling,

 As the second impeller 74b is rotated by the motor 71b of the air supply blower 70b, the second impeller 74b is rotated to generate a force capable of discharging the air introduced below the inside of the main body 2b into the building. Foreign matter in the air is primarily removed while passing through the filter unit 40b including the pretreatment filter 41b and the intermediate filter 42b that are horizontally mounted inside the upper end of the main body housing 10b. The pretreatment filter 41b ) And the electrostatic precipitator 50b mounted between the intermediate filter 42b form a secondary electric field to charge the foreign matter in the air and move to each polarity to remove it. As such, the air passing through the filter part 40b and the electrostatic precipitator 50b passes through the air supply blower 70b mounted in the interior of the indoor body 2, and the coil part 80b mounted at the bottom of the air supply blower 70b. ) And the bypass damper (83b) are moved. At this time, in the coil portion 80b, a coil 81b through which cooling water or hot water passes is densely mounted in a rectangular frame, and the two frames face each other and are installed in a '∧' shape, whereby air discharged downwards is formed. The bypass damper 83b mounted on both sides of the coil 81b is cooled or heated while passing through the coil 81b, and the duct is opened up and down and the valve is mounted to adjust the open space according to the rotation of the valve. As a result, the amount of air passing by can be adjusted to control the amount of air and the degree of heating or cooling.

As such, the air passing through the coil unit 80 is mounted with a funnel-shaped hopper 85b mounted at the lower end of the main body housing 20b, and a discharge unit 90b is mounted under the hopper 85b.
