Claims

[Scope of utility model registration request]

(1) A refrigeration cycle is constituted by an indoor heat exchanger, a compressor, and an outdoor heat exchanger, and an outdoor fan is installed next to the outdoor heat exchanger, and the compressor and the outdoor heat exchanger are connected to each other via a common first relay. The first set temperature is supplied to each fan, and the indoor temperature is compared with the first set temperature.
11. In the air conditioner that controls the first relay based on the output of the comparator to control the indoor temperature to a first set temperature, the outdoor fan is provided with a high-speed rotation tap.11.
A common end of a second relay is connected to a power supply line extending from the first relay to the outdoor fan. A normally-closed contact of this second relay is connected to the tap for ultra-high-speed rotation, and a timer circuit is provided to output a predetermined voltage for a certain period of time. The second set temperature is compared with the second set temperature which is set lower.
An outdoor fan control device for an air conditioner, characterized in that a comparator is provided, and the second relay is operated based on the AND output of the timer circuit and the second comparator.

(2) The outdoor fan control device for an air conditioner according to claim 1, wherein the first set temperature to be compared by the first comparator can be changed.
