CONSTITUTION:The outdoor side coil 11, a bypass damper 12 and an exhaust fan 13 are provided in the ventilating air chamber 6. Atmosphere OA, induced by an air feeding fan 10, is introduced into an air feeding chamber 5, dampers 16, 18 and an indoor side coil 9 from an atmosphere gallery 23 and a part of it is introduced into the outdoor side coil 11. On the other hand, returning air RA, induced by the exhaust fan 13 and sent through the damper 18, is being introduced into the outdoor side coil 11, therefore, a part of the feeding air OA, being sent into the outdoor side coil 11, is joined with the returning air, is passed through the outdoor side coil 11 and the returning air RA receives heat exchange. According to this constitution, the heat of the returning air may be retrieved and the effective utilization of the heat may be contrived.

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention provides a heat I-pump air εI! system that can reduce running costs from the viewpoint of a mechanism. , relating to a summation device.

Conventionally, in the case of an air conditioner for air conditioning the interior rooms of I and V rooms of medium-to-high-rise buildings, etc., the air from the living room is discharged to the outdoors in its original state.

Therefore, the reality is that a large amount of heat is wasted without being effectively utilized. On the other hand, the running cost of air conditioners tends to increase due to the operating energy, and therefore, there is a need for measures that can reduce the running cost from the mechanical standpoint.

Therefore, the present invention provides a pump air conditioner capable of addressing the above-mentioned problems.

However, in this invention, an outdoor coil is installed in the air chamber of a closed casing, and all or part of the air discharged outdoors through the air chamber passes through the outdoor coil. It is designed to recover the heat from the air through heat exchange during the process.

Hereinafter, this invention will be specifically explained based on the drawings.

In the figure, ■ is a living room, 2 is an air conditioner room, and 3 is a Bee 1-pump air conditioner installed in the air conditioner room 2.

Each element of the heat pump air conditioner 3 is arranged in an air supply chamber 5 and a return air chamber 6 of the closed casing 4.

In the air supply chamber 5, a compressor 7. Filter 8. An indoor coil 9 and an air supply fan 1o are installed, and an outdoor coil 11. A bypass damper 12 and an exhaust fan 13 are installed. Further, in the partition wall 14 between the air supply chamber 5 and the return air chamber 6, a damper 16 is installed on the air supply chamber 5 side of the partition wall 15, and a damper 17 is installed on the air luck chamber 6 side of the partition wall 15. , a damper 18 installed in a portion of the partition wall 14 located outside the partition wall 15, and a damper 19 installed in a portion of the partition wall 14 located inside the partition wall 15. , these are 1
A four-way single-axis simultaneous operation type damper 21 is installed, which is operated simultaneously by a book operation shaft 20.

The four-way single-axis simultaneous operation type damper 21 is operated by a motor (pulse motor, stethop motor, etc.) 22, and
The control is performed by a signal from a CO2 sensor (not shown) installed in the living room or the like. The damper 16
The opening degree of the damper 18 is adjusted in accordance with the required amount of outside air, and the opening degree of the damper 18 is adjusted in inverse proportion to this. The opening degree of the damper 19 is adjusted according to the required amount of return air, and the opening degree of the damper 17 is adjusted in inverse proportion to this. These dampers 16-1
9 is interlocked when the operating shaft 20 is rotated.

At this time, the dampers 16 and 17 and the dampers 18 and 19 are in a proportional relationship, respectively.

In such a P1-pump air conditioner 3, the suction force of the air supply fan 10 causes 0.0. A is introduced.

Outside air introduced 0. A is divided into a flow toward the indoor coil 9 and a flow toward the outdoor coil II depending on the opening degree of the damper 16 and the damper 18.

The air headed for the indoor coil 9 is cleaned by the filter 8, then temperature-controlled (cooled or heated) by the indoor coil 9, and then sent to the supply air duct 24. Living room 1 via blowout slot 25
(S, A) is introduced into the perimeter zone within. The air flowing toward the outdoor coil 11 merges with the return air R and A flowing in via the damper 18 due to the suction force of the exhaust fan 13 and passes through the outdoor coil 11 . □ During this passage, the return air R3A undergoes heat exchange and is discharged outdoors via the exhaust louver 26 (E, A). The return air R, A that passes through the outdoor coil 11 may be all or part of the air that has passed through the exhaust fan 13. In all cases, the bypass damper 12 is closed, and when the bypass damper 12 is open, an amount corresponding to the opening amount passes through. The opening degree of the bypass damper 12 is automatically proportionally controlled by a thermostat (not shown) installed in the living room 1 or the like. This changes the amount of return air R, A passing through the outdoor coil 11, and adjusts the cooling or heating capacity. The return air R, A from the living room 1 flowing into the return air chamber 6 from the return air duct 27 is transferred to the outdoor coil 11 according to the opening degree of the damper 17 and the damper 19.
The current is divided into one directed to the indoor coil 9 and one directed to the indoor coil 9. The air flowing toward the outdoor coil 11 is the outside air flowing from the damper 18 as described above. It merges with a part of A and passes through the outdoor coil 11. Also, the outside air flowing into the indoor coil 9 from the damper 16 is 0. The mixture is mixed with A, cleaned by a filter 8, and passed through an indoor coil 9.

In the illustrated case, the conditioned air S, A that has flowed into the perimeter zone in the living room 1 through the outlet slots 1 to 25 merges with the indoor air and exchanges heat, and then passes through the passage 28 of the perimeter zone and reaches the ceiling wall thereof. Ejection slot 2 provided
9 into the return air duct 27. The passage 28 of the verimake zone is composed of an outer wall window glass 30 and a sunlight reflecting barrier 31, and the return air R08 flowing through the passage 28 and the sunlight reflecting barrier (including the blind 32) 3
1 reduces heat loads such as through-flow heat and solar radiation in the perimeter zone. A damper 33 that is opened by the return air R9A is provided at the lower end of the sunlight reflecting barrier 31 to prevent cold draft from the perimake zone from entering the interior zone when the interior zone is not air-conditioned. .

In summary, in the heat pump air conditioner according to the present invention, the outdoor coil is installed in the air chamber of the closed casing, and all or part of the air discharged outdoors through the air chamber is transmitted through the outdoor coil. Since it is designed to pass through the outdoor coil, the heat of the air passing through the outdoor coil can be recovered by heat exchange. Therefore, since the recovered heat can be used for indoor coil heat, running costs can be reduced from a mechanical standpoint.
