Abstract

An air flow switching type air conditioner device for both cooling and heating. The air conditioner device including a compressor (4), a condenser (3), an evaporator (2), and a refrigerant pipe (9) connecting the compressor, the condenser, and the evaporator. The device includes an air blower (10), a case (1) with an indoor side discharge port (11) and an indoor side intake port (12). Both the indoor ports (11, 12) being openable towards the inside of a room. The device further includes an outdoor side discharge port (13) and an outdoor side intake port (14), with both outdoor ports openable to the outside of a room and separately partitioned by partition walls (25,26) The device includes a heat exchange chamber (20) positioned between the indoor side discharge port and the indoor side intake port and between the outdoor side discharge port and the outdoor side intake port. The device further includes a series of dampers that are moveable to control flow of air through the ports. The device also includes a controller connected to and arranged to individually control the opening and closing of the dampers.

Claims

1. An air flow switching type air conditioner for both cooling and heating, comprising:

a compressor (4);

a condenser (3);

an evaporator (2);

a refrigerant pipe (9) connecting the compressor, the condenser, and the evaporator;

an air blower (10);

a case (1) comprising an indoor side discharge port (11) and an indoor side intake port (12), both the indoor ports (11, 12) being openable towards the inside of a room, and an outdoor side discharge port (13) and an outdoor side intake port (14), both outdoor ports openable to the outside of a room and separately partitioned by partition walls (25,26);

a heat exchange chamber (20) positioned between the indoor side discharge port and the indoor side intake port and between the outdoor side discharge port and the outdoor side intake port;

a first damper (31) provided between the evaporator and the indoor side discharge port;

a second damper (32) provided between the condenser and the indoor side discharge port;

a third damper (33) provided between the indoor side intake port and the evaporator;

a forth damper (34) provided between the indoor side intake port and the condenser;

a fifth damper (35) provided between the outdoor side discharge port and the evaporator;

a sixth damper (36) provided between the condenser and the outdoor side discharge port;

a seventh damper (37) provided between the outdoor side intake port and the evaporator;

an eighth damper (38) provided between the outdoor side intake port and the condenser;

said dampers moveable to control flow of air through said ports ; and

a controller connected to and arranged to individually control the opening and closing of the dampers.

2. The air flow switching type air conditioner for both cooling and heating according to claim 1, wherein the heat exchange chamber is partitioned into upper and lower heat exchange chambers (22,23) by a horizontal partition plate (21) so that the evaporator is arranged in the upper heat exchange chamber (22) and the condenser is arranged in the lower heat exchange chamber (23), whereby condensing water produced in the evaporator flows down to the condenser.

3. The air flow switching type air conditioner for both cooling and heating according to claim 2, further comprising a humidity sensor (7) that is providable at a predetermined position in an interior of a room, and a reheater (6) is connected between the condenser and an expansion valve (5) or capillary tube, and wherein the reheater is positionable between the evaporator and the indoor air discharge port in order to heat air discharging into the inside of a room.

4. The air flow switching type air conditioner for both cooling and heating according to claim 1, further comprising a humidity sensor (7) that is providable at a predetermined position in an interior of a room, and a reheater (6) is connected between the condenser and an expansion valve (5) or capillary tube, and wherein the reheater is positionable between the evaporator and the indoor air discharge port in order to heat air discharging into the inside of a room.
