First, the main body (A) is installed in the vicinity of the room, and the blower air supply port portion is directly connected to the terminal unit installed in each room through the duct. Thus, the total amount of outside air taken in from the air intake (a) is SA for air supply.
When the blower (1) is operated, it passes through the blower circuit A1 and flows backward from the blower port (1) 'to each terminal unit (B) to perform air conditioning by the outside air.

In the case of determining the required amount of outside air other than air conditioning such as cooling by the whole outside air, a part of it is passed through the total heat exchanger (5) by the adjustment operation of the damper (9) for adjusting the outside air, and the blower circuit is provided.
Air is blown from the blower port (1) 'via A2.

In addition, the air blower (2) for exhaust and the exhaust RA blower (2) are actuated at the same time as the air is supplied, and the polluted air in the room that is returned to the inside of the machine through the duct (not shown) is returned to the inside of the exhaust damper ( When the valve of 11) is opened, the whole amount is exhausted to the outside air from the exhaust port (d) through the blower circuit B1.

When the amount of heat required for the exhaust is as described above, the total amount of the exhaust gas or a part thereof is passed through the total heat exchanger (5) by adjusting the opening / closing of the total exhaust damper (11).

It should be noted that the return air from the return air port (c) does not flow partially or entirely toward the total heat exchanger (5) by adjusting the opening and closing of the RA bypass damper (10) and exhaust adjustment damper (12). Ventilation circuit (B3) on the side to let the air merge with the outside air.

(Embodiment) The following will describe the embodiments of the present invention with reference to the drawings. An outside air intake (a), a return air inlet (c), an exhaust outlet (d) are provided at appropriate places on the upper portion of the main body (A). , And air inlets and outlets such as the air supply port (a) are provided at the side portions, and duct piping is provided at each of the mouth portions to connect with the terminal unit (B) installed on the indoor side.

Inside the airframe, the outside air intake (a) and the air supply port (a) are communicated with each other, and a substantially L-shaped blower circuit (A1) and an indoor return air vent (c) and an exhaust are provided alongside the blower circuit. A substantially U-shaped blower circuit (B1) that communicates the mouth (D) is formed.

In addition, in the blower circuit (A1), the SA blower for air supply (1)
, The total heat exchanger (5) is placed upright or obliquely on the upper part,
RA blowers (2) for return and exhaust are arranged in the blower circuit (B1).

Further, a part of the blower circuit (A1) for adjusting all outside air, and a blower circuit (B1) for changing the air flow switching such as RA bypass damper (10), all exhaust dampers (11), and exhaust adjustment dampers (12). A damper is provided, and the flow direction of the air flowing through the circuit can be arbitrarily changed according to each purpose.

As another embodiment of the present invention, a heat exchange coil such as a cooling coil (3) and a heating coil (4) is obliquely installed in the same plane on the side portion of the main body (A) as shown in FIG. The coils are arranged in a V-shape, an inverted V-shape, a W-shape, etc. in the left-right and front-rear directions, and the upper part of the coil is branched into a plurality of air ducts (C1) and (C2) by a partition plate (15) And each air duct (C
1), Air supply ports (a) and (b) that can be opened in the upper part of the flow dividing chamber (C) by connecting and connecting the air flow rate adjusting mechanisms (16) and (16) in the chamber (C2) The terminal unit (B) installed on the indoor side can very easily request different air-conditioning development in a room with completely different air conditions such as interior zone and perimeter zone from the terminal unit (B) installed on the indoor side. .

In the figure, reference numerals (6), (7), and (8) represent main and prefilters, and the terminal unit (B) is not shown in the figure, but a cooling / heating heat exchanger, a humidifier, The necessary air conditioning mechanism members such as a drain pan, an auxiliary filter, a control sensor, a valve mechanism, an air volume adjusting device, and a sound deadening mechanism are incorporated.
