Abstract

Circuito de control de descongelación para un acondicionador de aire que realiza tanto funcionamiento de calefacción como de refrigeración comprende un interruptor para conmutar una energía eléctrica suministrada a una válvula para invertir una dirección de circulación de un refrigerante; una parte de detección de temperatura provista de un sensor de temperatura semiconductor para detectar si un intercambiador de calor exterior desciende por debajo de una temperatura que requiere una operación de descongelación; y una parte de excitación de interruptor para cortar la alimentación de energía eléctrica a la válvula en respuesta a una señal de salida de la parte de detección de temperatura en la que el interruptor se desconecta cuando la temperatura del intercambiador de calor exterior desciende por debajo de la temperatura que requiere la operación de descongelación.Defrost control circuit for an air conditioner that performs both heating and cooling operation comprises a switch for switching an electrical power supplied to a valve to reverse a direction of circulation of a refrigerant; a temperature sensing part provided with a semiconductor temperature sensor for detecting if an outdoor heat exchanger falls below a temperature that requires a defrost operation; and a switch driving part for cutting off the electrical power supply to the valve in response to an output signal from the temperature sensing part in which the switch is turned off when the temperature of the outdoor heat exchanger drops below the temperature that the defrosting operation requires.
