われた。 In air-type air-cooling/heating type air conditioners, when the outside temperature is high during heating, the high-pressure pressure switch that senses the pressure stops operation to prevent the pressure in the high-pressure side refrigerant circuit from rising excessively for the safety of the equipment. ing. Conventionally, in order to widen the operating range of this type of air conditioner to avoid the above-mentioned shutdown, the fan of the outdoor unit was turned on and off, and electronic stepless control was performed.

もあるが、省エネルギーの点からは不利である。 However, the former lacks comfort in an air-conditioned space due to rapid changes in conditions, while the latter suffers from problems such as magnetic noise from the fan motor. Furthermore, in some indoor units, the rotational speed of the indoor fan motor is increased due to the increase in high pressure, but this is disadvantageous from the point of view of energy conservation.

を目的としている。 This idea was made in order to eliminate the drawbacks of the conventional ones as mentioned above.The outdoor unit has two fans, each with a different air volume, and one of the fans is selected depending on the condition of the unit. ON−
The aim is to expand the operating range by turning the vehicle OFF without compromising comfort or causing problems with magnetic noise.

1 and 3' are the normally open contacts of contactor No. 13', and 4 is the contactor No. 2 and 4' for fan motor No. 22.
No. 24 is a normally open contact, 5 is a pressure sensor that detects the pressure of the high pressure side refrigerant circuit during heating, and 6 is a pressure sensor 5
This is a discrimination circuit that discriminates the pressure sensed by.

Both fan motors No. 11 and No. 22 are running. When the pressure in the high-pressure side refrigerant circuit rises to the set pressure due to a rise in outside air temperature, the pressure sensor 5 senses the pressure, and the discrimination circuit 6 determines the rate of increase in pressure. If the speed is below the set speed, fan motor No. 22 with the smaller air volume is selected and stopped. Then, when the pressure in the high-pressure side refrigerant circuit decreases, the operation is restarted again.
以後この動作を高圧側冷媒回路の圧力の変化に
応じて繰り返す。 Thereafter, this operation is repeated according to changes in the pressure of the high-pressure side refrigerant circuit.
