制御を行なうことを目的とする。Conventional technologyConventional air conditioners have the same outdoor fan speed during heating operation and during heating low temperature operation (from one defrosting operation to the next defrosting operation) [hereinafter referred to as low temperature operation].Control details Are you being controlled by? Q. What is the problem that the invention aims to solve? With conventional control, the outdoor fan speed control during heating operation and low temperature operation is the same, but a difference occurs in the outdoor heat exchanger capacity during both operations, which causes problems like during low temperature operation. As the load increases, the outdoor heat exchanger frosts up faster, and the heating capacity of the air conditioner cannot cope with the load.For example, the unit is the change in capacity for one cycle from the start of low-temperature operation to the end of defrosting operation. Expressed in terms of time (hereinafter referred to as integrated capacity), there is a tendency for this capacity (hereinafter referred to as integrated capacity) to decrease significantly during low-temperature heating operation. The purpose is to perform load-based control only when the temperature is below the specified temperature.
課題を解決するための手段
上記課題を解決するために本発明(よ 外気温度がある

ァン速度制御を変更するものである。Means for Solving the Problems In order to solve the above problems, the present invention (1) changes the outdoor fan speed control during heating operation only when the outside air temperature is below a certain specified temperature.
作用
本発明は 外気温度がある一定の規定温度以下の場合に
限り暖房運転時に室外ファン速度を上げることにより、
着霜の戊長を少なくし 低温運転時の高温風吹出しを実

する。Effect: The present invention increases the speed of the outdoor fan during heating operation only when the outside air temperature is below a certain specified temperature.
This reduces the length of frost formation and enables high-temperature air to be blown out during low-temperature operation, which in turn makes it possible to improve the integration capacity during low-temperature operation.
実施例

First, the first embodiment of the present invention will be described with reference to FIG. When a heating operation instruction is issued by a remote control or forced operation (step 1), the air conditioner starts operating (step 2).

を繰り返し行なう。At the same time, the comparing means 7 compares the outside air temperature T1 sampled by the outside air temperature detecting means 5 with the specified outside air temperature T1 determined by the outside air temperature setting means 6 (step 3), thereby determining the outside air temperature. As a result of this determination, if the outside air temperature is lower than the specified outside air temperature, the outdoor fan speed (rotation speed) is increased by the outdoor fan switching means 8, output means 9, and outdoor fan 10 (step 4). After that, the outside air temperature is sampled again and the outside air temperature is determined. Repeat this operation thereafter.
