For example, when the room temperature increases, the voltage output increases, and accordingly, the temperature of the heater increases, causing the expansion valve to open. Also, when the room temperature decreases, the voltage decreases, and accordingly, the temperature of the heater decreases and the expansion valve closes. Additionally, this expansion valve is equipped with a temperature-sensitive tube, making it easy to prevent liquid back-up.

し、膨張弁４を制御し、冷媒の冷却コイル２への流入量
を調整する。Next, the operation of this device will be explained. Based on the temperature detected by a thermometer 10 installed indoors, a controller 11 adjusts the voltage passing through the triac 8. Since the amount of heat generated by the microheater 7 changes depending on the magnitude of this voltage, this is detected by the temperature sensing cylinder 6, and the expansion valve 4 is controlled to adjust the amount of refrigerant flowing into the cooling coil 2.

ントローラ１１で制御する。そのため、マイクロヒータ
７の発熱量が大となり、膨張弁４の開度が大となって、
流入冷媒量が増えるので、室内の冷却効果が大きくなる
。For example, when the room temperature is higher than a set value, the controller 11 controls the triac 8 so that the portion to be cut is reduced. Therefore, the amount of heat generated by the micro heater 7 becomes large, and the opening degree of the expansion valve 4 becomes large.
Since the amount of inflowing refrigerant increases, the indoor cooling effect increases.
逆に、室内温度が、設定値よりも低い時は、トラ・ｒア
ツク８により、カットされる部分が大となるようにコン
トローラ１１で制御する。そのため。On the other hand, when the indoor temperature is lower than the set value, the controller 11 controls so that the area to be cut by the tractor 8 is increased. Therefore.
マイクロヒータ７の発熱量が小となり、膨張弁４の開度
が小となって、流入冷媒量が小となるので室内の冷却効
果が小さくなる。The amount of heat generated by the micro heater 7 becomes small, the opening degree of the expansion valve 4 becomes small, and the amount of inflowing refrigerant becomes small, so that the indoor cooling effect becomes small.
さらに、均圧管５、感温＠６を有しているので圧縮機へ
の液バツクを防止できる。Furthermore, since it has a pressure equalizing pipe 5 and a temperature sensor @6, liquid backflow to the compressor can be prevented.

以上のように本発明によれば、従来の電動弁を用いた装
