Abstract
An air conditioner having an indoor unit and an outdoor unit. The indoor unit has a compressor, an indoor heat exchanger, and a indoor fan. The outdoor unit has an outdoor heat exchanger, a capillary tube, and an outdoor fan. In use, the indoor unit is connected to a commercial AC power supply. A driving circuit is provided in the indoor unit, for applying a voltage via a power-supply line to the outdoor unit to drive the outdoor fan. This voltage is lower than the voltage of the commercial AC power supply. Thus, the power-supply line can be connected to the indoor and outdoor units, with ease and in safety.
Claims8
An air-conditioning apparatus comprising:
- an outdoor unit having an outdoor heat exchanger, an expansion device, and an outdoor fan for circulating outdoor air via said outdoor heat exchanger;
- an indoor unit to be connected to a commercial AC power supply and having a compressor, an indoor heat exchanger, and an indoor fan circulating indoor air via said indoor heat exchanger;
- a driving circuit provided in said indoor unit, for applying a voltage lower than a voltage applied from the commercial AC power supply, to drive said outdoor fan;
- and
- a power-supply line for applying the output voltage of the driving circuit to said outdoor unit.
- wherein said compressor, said outdoor heat exchanger, said expansion device, and said indoor heat exchanger are connected by pipes, thereby constituting a refrigerating cycle.
An air-conditioning apparatus comprising:
- an outdoor unit having an outdoor heat exchanger, an expansion device, and an outdoor fan for circulating outdoor air via said outdoor heat exchanger;
- an indoor unit to be connected to a commercial AC power supply and having a compressor, a four-way valve, an indoor heat exchanger, and an indoor fan circulating indoor air via said indoor heat exchanger;
- a driving circuit provided in said indoor unit, for applying a voltage lower than a voltage applied from the commercial AC power supply, to drive said outdoor fan;
- and
- a power-supply line for applying the output voltage of the driving circuit to said outdoor unit.
- wherein said compressor, said four-way valve, said outdoor heat exchanger, said expansion device, and said indoor heat exchanger are connected by pipes, thereby constituting a heat-pump type refrigerating cycle.
