ABSTRACT:
A room air conditioner of the air valve heat pump type wherein a solid state narrow differential thermal sensor is arranged on a heat exchange baffle that senses room ambient. The sensor is insulated to eliminate biasing the sensor with outdoor and component heat transfer. The sensor through the baffle follows room ambients and is cooled when the cooling cycle is terminated by cold air from evaporator located above the baffle and when the heating cycle is terminated the sensor is heated as warm air from the condenser located below the baffle rises over the baffle to raise the temperature of the sensor to prevent short cycling of the air conditioner on either the cooling or heating mode.
