Abstract

One end of a relay RY is connected to one end of the valve coil L1 of a 4-way switching solenoid valve, with a dc high voltage DC280V applied to the other end of the relay RY. The collector of a transistor Q1 is connected via a diode D1 to one end of the valve coil L1, with a dc low voltage DC16V applied to the emitter of the transistor Q1. When the valve coil L1 is to be energized, a control unit 1 is used to turn on the relay RY and a dc high voltage is applied to the valve coil L1 via the relay RY and a positive temperature coefficient element PTC to thereby perform a switching operation. After the switching operation, the control unit 1 is used to turn on the transistor Q1 and then turn off the relay RY to apply a dc low voltage to the valve coil L1 via the transistor Q1, thereby enabling a hold operation. Accordingly, a solenoid valve control device capable of reducing power consumption with a simple structure, and an air conditioner provided with the solenoid valve control device are provided.

Description

technical field [0001] The present invention relates to a solenoid valve control device for controlling the switching operation of a solenoid valve and an air conditioner provided with the solenoid valve control device. Background technique [0002] In the past, as an air conditioner with a solenoid valve control device, there was a kind of air conditioner in which the valve coil of the four-way switching solenoid valve was not energized during cold wind operation, and the four-way switching solenoid valve was located at one switching position. During operation, by energizing the valve coil of the four-way switching solenoid valve, the four-way switching solenoid valve is switched to the air conditioner on the other switching position. [0003] However, in the above-mentioned air conditioner with the electromagnetic valve control device, since the valve coil of the four-way switching electromagnetic valve is always energized during the heating operation, there is a disadvant...
