Abstract

En un acondicionador de aire tipo bomba de calor, se conecta la salida de refrigerante del compresor en un ciclo de refrigeracion del mismo a unpuerto de entrada de refrigerante de un termointercambiador de exterior mediante un tubo de derivacioncon una válvula de cierre, y sensores de temperaturadetectan las temperaturas de los lados de entrada y salida de refrigerante de termointercambiador de exterior. En un modo de operacion decalefaccionamiento, cuando la temperatura del lado deentrada y de salida de refrigerante alcance un cierto valor o un valor inferior que requiere ladescongelacion, la válvula de cierre del tubo de derivacion se abre para iniciar la descongelacion utilizando el método de descongelacion porderivacion degas calien te. La temperatura del lado de salida de refrigerante se detecta a intervalos de tiempo específicos de manera que si la velocidad decambio de temperatura es menor o igual que un valor predeterminado, la válvula de cierre se cierra y laválvula de cua tro pasos de un ciclode refrigeracion cambia su posicion al modo de operacion de enfriamiento para cambiar el método de descongelacion inversa que permite que un gas calientefluya en direccion inversa desde el compresor altermointercambiador de exte rior, por lo tanto se permite que el termointercambiador de exterior se descongelerápidamente.
