Claims (1)

[Scope of utility model registration request] A heat pump type air conditioner for both heating and cooling, which includes at least one first room temperature detection element located at an appropriate position for controlling room temperature during cooling, and at least one first room temperature detecting element located at an appropriate position for controlling room temperature during heating. at least one second room temperature detection element disposed at the second room temperature detection element, and a temperature adjustment circuit capable of receiving signals from the room temperature detection element and controlling the air conditioner to maintain a desired operating state; a first switching means for supplying and cutting off operating current to a coil that drives a four-way valve that switches between a cold circuit and a warm circuit of the refrigerant circuit;
When this operating current is interrupted or supplied, the first
responsive to the operating current for inputting the signal from the second room temperature detecting element to the temperature control circuit by switching the signal from the second room temperature detecting element when the operating current is supplied or cut off, respectively; Second to do
A heat pump air conditioner characterized by comprising: a switching means;
