 The present invention relates to an inverter type separated air conditioner, and particularly to utilization of waste heat from a power factor improving reactor.

[0002]

[Prior Art]

 In general, as a conventional separation type inverter air conditioner, there has been one that energizes a commercial power source as it is from the indoor side to the outdoor side as disclosed in JP-A-63-25447. As shown in FIG. 2, the conventional device is composed of a plug for receiving the commercial power source 1 from an outlet, a controller 3 of the indoor unit 2, a relay 4 for energizing the outdoor, an outdoor unit 5, etc., and the operation is started. Then, the relay 4 is turned on and the outdoor unit 5 is energized, and the outdoor unit 5 is operated. A heat exchanger 7 and an indoor blower fan 8 are provided in the air passage 6 of the indoor unit 2, and are connected to the outdoor unit 5 and an outdoor heat exchanger 10 and a compressor 11 by a pipe 9 with the outdoor unit 5. Reference numeral 12 is a power factor improving reactor, 13 is a diode stack, 14 is a voltage doubler capacitor, 15 is a smoothing capacitor, 16 is a power transistor, which constitutes an inverter unit and is disposed in the outdoor unit 5 and is provided with a terminal block 17, It is connected to the relay 4 through the terminal block 19 of the indoor unit 2 by the connecting wire 18. Reference numeral 20 is an outdoor controller, and 21 is an outdoor blower fan.

[Problems to be solved by the device]

 Since the conventional separated inverter air conditioner is configured as described above, the heat generating parts of the inverter such as the power factor improving reactor, power transistor, diode stack, etc. are arranged in the outdoor unit, and the heat is simply discarded. On the contrary, in order to suppress the temperature rise, it was necessary to take measures such as ventilation to radiate heat. Also, in order to dehumidify without lowering the room temperature, it was necessary to install a reheating mechanism such as a heater in the indoor unit.

The present invention has been made to solve the above problems, and an object thereof is to provide a separated inverter air conditioner that simplifies ventilation measures for an outdoor unit and reuses heat generated by components. .

[0005]

[Means for Solving the Problems]

 A separate inverter air conditioner according to the present invention is composed of an indoor unit and an outdoor unit, and in a separate air conditioner equipped with an inverter that drives a compressor at a variable frequency, a power factor that is a component of the inverter. The improvement reactor was installed in the air passage of the indoor unit.

[0006]

[Action]

 In the separated inverter air conditioner according to the present invention, the waste heat of the reactor acts as an auxiliary to the heating capacity during heating, and acts as a reheating source for dehumidification operation that does not lower the room temperature during cooling and dehumidification.

【Example】

 An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a block diagram of a separate inverter air conditioner showing an embodiment of the present invention. In the figure, 1 is a commercial power source, 2 is an indoor unit, a relay 4 for energizing the power source outside the room, an indoor controller 3, a terminal block 19, a power factor improving reactor 12 disposed in the air passage 6, a blower fan. 8, the heat exchanger 7, and the power factor improving reactor 12 is connected between the relay 4 and the terminal block 19.

Next, the operation will be described. First, when the commercial power supply 1 is energized to the indoor unit 2, the indoor controller 3 composed of a microcomputer operates, and when a remote controller (not shown) or the like issues an operation start command, the relay 4 turns on. The outdoor unit 5 is energized via the power factor improving reactor 12 installed in the indoor unit air passage 6, the terminal block 19, and the connection line 18, and the indoor controller 3 turns the blower fan 8 to start air conditioning. Next, when the outdoor unit 5 is energized, the outdoor controller 20 composed of a microcomputer or the like starts to operate and rotates the blower fan 20, while the compressor 11 includes a diode stack 13 times voltage capacitor 13, The power source, which has been turned into a direct current by the capacitor 15, is turned into an alternating current by the power transistor 16 and is energized.

In the separated inverter air conditioner configured as described above, a reactor with a large current and a large amount of heat generation is installed in the air passage of the indoor unit, so that waste heat of the reactor is supplemented to the heating capacity during heating. As a result, it can be used as a reheating source for dehumidification operation that does not lower the room temperature during cooling and dehumidification.

[0010]

[Effect of the device]

 As described above, according to the present invention, in the separated inverter air conditioner, the reactor is installed in the air passage of the indoor unit. The improvement effect can be obtained, and when cooling or dehumidifying, the waste heat of the reactor can be used as a reheating source for dehumidifying operation that does not lower the room temperature, and it is not necessary to use a heater, and the cost can be reduced. Furthermore, since the amount of heat generated by the outdoor unit can be reduced, ventilation measures for the outdoor unit can be simplified.
