Abstract

(과제)(assignment)

펌프와 수온센서와 열원에 의해서 가열되는 열교환기를 구비하는 강제순환회로와, 외기온도를 검지하는 외기온도센서와, 물이 동결될 우려가 있는 기준온도 이하로 외기온도센서의 검지온도가 저하되었을 때에는 설정 시간만큼 펌프를 작동시키는 동결방지동작을 휴지시간(B)마다 반복시키는 펌프제어회로를 구비한 강제순환회로의 동결방지장치에 있어서, 동결방지동작이 필요 이상으로 반복되는 문제점을 방지한다.The forced circulation circuit including a pump, a water temperature sensor, and a heat exchanger heated by a heat source, an outside air temperature sensor for detecting the outside temperature, and a detection temperature of the outside air temperature sensor falls below a reference temperature at which water may freeze. In the freezing prevention device of the forced circulation circuit having a pump control circuit for repeating the freezing prevention operation for operating the pump for a set time for each idle time B, the problem that the freezing prevention operation is repeated more than necessary is prevented.

(해결수단)(Solution)

상기 외기온도센서의 검지온도가 저하함에 따라서 짧아지도록 또 동결방지동작 후의 상기 수온센서의 검지온도가 저하함에 따라서 짧아지도록 외기온도센서의 검지온도와 수온센서의 검지온도의 쌍방에 의거하여 상기 휴지시간(B)을 설정하는 휴지시간설정회로를 구비한다.The idle time is based on both the detection temperature of the outside air temperature sensor and the detection temperature of the water temperature sensor so as to shorten as the detection temperature of the outside air temperature sensor decreases and to shorten as the detection temperature of the water temperature sensor after freezing prevention operation decreases. A pause time setting circuit for setting (B) is provided.
