Indoor unit is shown. The indoor unit of the system type package air conditioner is an indoor unit of the heat pump device J as a heat exchanger that controls the temperature of the air taken in from the return air port 20a as the intake port and discharged from the air supply port 20b as the exhaust port. The heat exchanger 1 for a room and the controller H of the heat pump device J as a controller for controlling the operation of the indoor heat exchanger 1 are housed in the casing P of the indoor unit. .

As shown in FIG. 5, the heat pump J includes two indoor air heat exchangers 1, outdoor air heat exchangers 2, a compressor 3, an accumulator 4, a four-way valve 5 and a one-way valve. The refrigerant system K in which the expansion valves 6 and 7 and the liquid receiver 8 are connected by a refrigerant pipe and two air passage systems, that is, the return air RA from the air-conditioning target area is supplied to the indoor air heat exchanger 1. The temperature control is performed by ventilation, and the temperature-controlled air supply system 9 supplies the temperature-controlled air supply SA again to the air-conditioning target area by the air supply fan 9 and the outside air OA for heat exchange with the outdoor air. The air passage system B is configured to ventilate the device 2 and exhaust the vented exhaust air EA to the outside air again by the exhaust fan 10. The refrigerant system K can be switched between the case where the indoor air heat exchanger 1 functions as a condenser and the case where it functions as an evaporator by reversing the circulation direction of the refrigerant by the switching operation of the four-way valve 5. A system-type packaged air conditioner is provided for both heating and cooling operations. In the heating operation, the expansion valve 6 functions and the expansion valve 7 does not function as a one-way valve, while in the cooling operation, the expansion valve 7 functions and the expansion valve 6 functions as a one-way valve. It is configured to not work. Further, the air passage system A is provided with a damper 11 for adjusting the amount of the return air RA to be ventilated in the indoor air heat exchanger 1, and the air passage system B is ventilated to the outdoor air heat exchanger 2. A damper 12 that adjusts the amount of introduced outside air OA is provided. Further, between the air passage system A and the air passage system B, an air passage C that guides the outside air OA to the indoor air heat exchanger 1, and an air passage D that guides the return air RA to the outdoor air heat exchanger 2. By adjusting the damper 13 provided in the air passage C and the damper 14 provided in the air passage D, it is possible to simultaneously perform the ventilation operation while performing the temperature control operation for the air conditioning target area. A system type package air conditioner is configured.

As shown in FIG. 1, FIG. 2, FIG. 3, and FIG. 4, the casing P of the indoor unit of the system type package air conditioner includes a base frame 15 and a bottom plate 16 assembled on the base frame 15. The side plate 17, the front plate 18, the rear plate 19, and the upper plate 20. The inside of the casing P is vertically divided by an intermediate table 21 as a partition member that divides the inside of the casing P into the air passage portion and the non-air passage portion, and a portion above the intermediate table 21 is an air passage portion. The portion below the intermediate table 21 is configured as a non-air passage portion.

An indoor air heat exchanger 1 is provided at a substantially central portion of a portion above the intermediate table 21 so as to partition a portion above the intermediate table 21 into left and right parts. The indoor air heat exchanger 1 is provided with a filter 22 on its air intake side and a humidifier 23 on its air discharge side. Further, the upper plate 20 is provided with a return air port 20a for taking in the return air RA from the air conditioning target area into the casing P in a portion located on the right side of the indoor air heat exchanger 1, while In the portion located on the left side of the indoor air heat exchanger 1, there is provided an air supply port 20b through which the supply air SA whose temperature has been adjusted by the indoor air heat exchanger 1 is sent again to the air conditioning target area. Therefore, the return air port 20a, the indoor air heat exchanger 1, and the air supply port 20b form an air passage system A for temperature-controlled air. An air supply duct 9a and an air supply fan 9 are provided in the lower part of the air supply port 20b, and the air passage system A is blown. The damper 11 is provided below the return air port 20a, and is configured to adjust the intake amount of the return air RA. Further, in the portion of the rear plate 19 which is located above the intermediate table 21 and on the right side of the indoor air heat exchanger 1, the outside air OA which takes in the outside air OA to the air intake side of the air passage system A is introduced. A mouth 19a is provided. The outside air port 19a is provided with the above-mentioned damper 13 so that the intake amount of the outside air OA is adjusted.

The part below the intermediate table 21 is further divided into right and left parts by a partition plate 24, and the controller H of the heat pump device J is arranged on the left side part of the partition plate 24 on the right side part of the partition plate 24. Includes a compressor 3, an accumulator 4, a four-way valve 5, expansion valves 6 and 7, and a liquid receiver 8 as components other than the heat exchanger in the heat pump device J (four-way valve 5 and expansion). Valves 6 and 7 and receiver 8 are not shown). The controller H is composed of a control device (not shown) whose main part is a microcomputer, and an inverter (not shown) which controls the rotation speed of the drive motor. That is, the controller H adjusts the drive of the air supply fan 9, the exhaust fan 10, and the compressor 3, the switching of the four-way valve 5, the opening degree of the expansion valves 6 and 7, the operation of the humidifier 23, and the like. Thus, the operation of the heat pump J is controlled, and thus the temperature control operation of the indoor air heat exchanger 1 is controlled.

In the portion of the front plate 18 of the casing P located below the intermediate table 21, a part of the front plate 18 is configured as a separate body so that the non-air passage part is communicated with the outside. Three opening / closing panels 18a, 18b, 18c are provided as opening / closing bodies. Each of the open / close panels 18a, 18b, 18c is detachably attached to the casing P by a mounting screw 25. By removing any of the open / close panels 18a, 18b, 18c, only the non-air passage portion is removed. It can be opened to the outside and used for maintenance and inspection.

Further, a portion of the intermediate table 21 located on the right side of the partition plate 24 is separately configured as a removal panel 21 a, and is detachably attached to the casing P by a mounting screw 26. There is. Therefore, when the opening / closing panel 18a is removed, by further removing the removal panel 21a, maintenance and inspection work can be facilitated.

[Other Embodiments] In the above-described embodiments, the opening / closing body is composed of three panels as the opening / closing panels 18a, 18b, 18c, but is composed of one panel covering the entire non-air passage portion. It may be inserted or may be divided into four or more panels and further divided.

The partition member for partitioning the air passage portion and the other non-air passage portion is not limited to one that vertically divides the inside of the casing P like the intermediate table 21, but may be a front, rear, left, right, diagonal, or It may be a combination of partitions. Further, although the intermediate base 21 is configured so that a part thereof is detachable as the removal panel 21a, the entire intermediate base 21 may be detachably configured with respect to the casing P.

The casing P may be configured as an integrated system type package air conditioner such that the entire heat pump device J including the outdoor air heat exchanger 2 and the exhaust fan 10 is packaged.

It should be noted that reference numerals are added to the claims of the utility model for convenience of comparison with the drawings, but the present invention is not limited to the configuration of the accompanying drawings by the entry.
