Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to an air conditioner, and its purpose is to discharge air from a room facing south to the outdoors and to divert air from a room facing north to the south in summer. By supplying air to the room and mutually exchanging air in south-facing rooms and north-facing rooms in winter, air conditioning in summer and winter can be easily achieved, and energy such as electricity and kerosene can be saved. The purpose of the present invention is to provide an air conditioner that performs the following tasks.

Conventionally, indoor air conditioning in the summer has been achieved by installing indoor units 103 and 104 of air conditioners on the walls of a room 100 facing south and a room 101 facing north, as shown in Figure 1. Ta.

In this case, mass production tends to be higher in the south-facing room 100, but the temperature in the north-facing room is not so high, creating a temperature difference between the two rooms. However, this temperature difference was not used effectively, and a large amount of electricity was consumed to cool the hot south-facing room. Also, indoor air conditioning in winter is the second most important factor.
As shown in the figure, this was done using an oil stove 105 and a hot air fan 106, but in this case, as in the summer, there was a considerable temperature difference between the south-facing room 100 and the north-facing room 101. Despite this, it is not used at all, and each room is heated independently.
Energy was being wasted. The present invention is intended to eliminate these drawbacks, and embodiments thereof will be described below with reference to FIGS. 3 to 9. In the figure, 1 is a duct installed in the ceiling to communicate south-facing room 2, north-facing room 3, and the outdoors, and 4 is a duct installed in the ceiling to communicate south-facing room 2 and the outdoors. 5 is a duct installed in the ceiling to connect south-facing room 2 and north-facing room 3; 6 is a blower I installed at the intersection of ducts 1, 4, and 5; It has a motor 7, a blade 8 attached to the motor 7, and a damper 9 that switches the passage so that the south-facing room 2 and the outdoors or the south-facing room 2 and the north-facing room 3 are selectively communicated with each other. are doing. 10 is connected to duct 1,
Louver 11 is connected to the ceiling of room 2 facing south, louver 11 is connected to duct 5, louver 12 is installed on the ceiling of room 3 facing north, room 2 facing south and room 3 facing north. 13 is the duct 12 installed under the floor to communicate with the
A blower ■ installed in the middle of the air circulation passage 14 communicates with the duct 12 and the underfloor circulation passage 15 that circulates the air under the floor.
and a heat exchange element 16 provided at the intersection of the circulation passage 14 and the underfloor circulation passage 15 for mutually exchanging heat between the air blown from the north facing room to the south facing room and the underfloor air, Blades 17 for blowing air to each passage 14, 15
, 17″ motor 18 for rotating those blades,
It has a suction port 19 of the underfloor circulation passage 18 and a discharge port 20 of the underfloor circulation passage 15.

21 is a louver connected to the duct 12 and provided on the floor of the room 2 facing south; 22 is a louver connected to the duct 12 and provided on the floor of the room 3 facing north.

In the above configuration, in the summer, as shown in Figs.
When the blades 8 are rotated by the motor 7 installed inside the chambers , 6, the hot air from the south-facing room 2 is sucked in through the louver 10 and discharged outside through the ducts 1 and 4 as shown by the arrow A→A''. be done.

Also, when the blades 17, 17'' are rotated by the motor 18 installed inside the blower (1), 13, the cold air from the room 3 facing north is sucked in through the louver 22, and the air flows through the duct 12, as shown by the arrow B-+B''. The air that is supplied to the south-facing room through the circulation passage 14 and sucked in from the suction port 19 of the underfloor circulation passage 15 provided in the duct 1, 13 passes through the underfloor circulation passage 15 as shown by the arrow C→C''. Then, go under the floor from the discharge port 20.
It is discharged. At this time, the circulation passage 14 and the underfloor circulation passage 15
Mutual heat is exchanged by the heat exchange element 16 provided at the intersection of the two. Through these actions, the hot air in the south-facing room is exhausted outside, and at the same time, the cold air in the north-facing room is supplied to the south-facing room, so the south-facing room will be warmed up in a short time. It gets cooler. In addition, the air supplied from the north-facing room to the south-facing room exchanges heat with the cold air under the floor by the heat exchange element installed in the blower ■.
It becomes colder and is supplied to the room facing south. or,
In the case of winter, as shown in Figs. 6 to 8, the dampers 9 provided on the blowers 1 and 6 are switched to a position where the south-facing room 2 and the north-facing room 3 communicate with each other. When the blade 8 is rotated by the motor 7 installed inside the room 6, the warm air from the south-facing room 2 is sucked in through the louver 10, passes through the ducts 1 and 5 as shown by the arrow D→D'', and is released from the louver 11. It is supplied to room 3 facing north.

Also, when the blades 17, 17'' are rotated by the motor 18 installed inside the blower (1), 13, the cold air from the north-facing room 3 is sucked in through the louver 22, and the air flows through the duct 12, as shown by the arrow E-E''. The air that is supplied to the south-facing room through the circulation passage 14 and sucked in from the suction port 19 of the underfloor circulation passage 15 provided in the blower 1, 13 flows through the underfloor circulation passage 15 as indicated by the arrow F-+F''. and is discharged from the discharge port 20 to the underfloor.At this time, the circulation passage 14 and the underfloor circulation passage 15
Mutual heat is exchanged by the heat exchange element 16 provided at the intersection section. Through these operations, warm air from the south-facing room is supplied to the north-facing room through the duct installed in the ceiling, making the north-facing room warmer.
Also, the air passing through the ducts in the attic is warmed by the warm air in the attic and supplied to the north-facing rooms, and the air supplied from the north-facing rooms to the south-facing rooms is supplied by a blower.
The heat exchange element installed in the room exchanges heat with the warm air under the floor, so it is not very cold and there is no risk of lowering the temperature of the south-facing room. As described above, according to the present invention, in the summer, hot air from a south-facing room is discharged outdoors, and at the same time, cooler air from a south-facing room or a north-facing room is discharged to the outside. It also exchanges heat with the air under the floor, which is lower, and supplies it to the south-facing rooms.In winter, it supplies the relatively high-temperature air from the south-facing rooms to the north-facing rooms; By exchanging heat with the air under the floor, which has a higher temperature than the air temperature in the north-facing room, and supplying it to the south-facing room, air conditioning in summer and winter can be easily achieved while saving energy such as electricity and kerosene. This has the effect of making it possible to
