摘要： PURPOSE:To prevent the freezing of the titled heat collector efficiently by a method wherein when the ambient temperature is low, an anti-freezing device is operated at a water heating temperature higher than that when the ambient temperature is high. CONSTITUTION:When the difference between the temperature of the solar heat collector 1 detected by a heat collecting sensor 10 and the temperature of a hot water tank 2 detected by a heat collecting sensor 11 is higher than a predetermined value, heated water is circulated by operating a pump 3 through a control device 9. Further, an anti-freezing sensor 12 is provided in the heat collector 1 so as to detect the temperature T of the heated water and the ambient temperature To is detected by an open air sensor 13. In this case, when the ambient temperature To is low (for example, To1), the pump 3 is operated at the temperature T1 of the heated water (or T2 when the ambient temperature is To2) which temperature T1 is higher than that when the ambient temperature To is high (for example, To2), to thereby prevent the heat collector 1 from freezing.

摘要： PURPOSE:To perform stable control, by integrating a temperature detection output signal and using the integrated signal to actuate or stop an air conditioner. CONSTITUTION:The output terminals A, B of a temperature detection circuit 1, which is a bridge circuit composed of resistors 5, 6, 7 and a negative-characteristic temperature sensor 8, are connected to an integration circuit 2 which comprises an operational amplifier 9 and a capacitor 10 which serves as a feedback impedance. The output terminal C of the integration circuit 2 is connected to a switching circuit 3 which comprises reference potential determining resistors 11, 12, an operational amplifier 13, a transistor 14, a feedback resistor 15 for effecting positive feedback from the output terminal of the amplifier 13 to its uninverted input terminal and resistors 16, 17 for applying bias to the base of the transistor 14. Switching is effected by an excitation winding 4. Feedback is effected from the output terminal of the amplifier 13 to the inverted input terminal of the other amplifier 9 through another resistor 18 to determine the hysteresis width of the switching circuit 3.

摘要： PURPOSE:To make it possible to start the air conditioner immediately if only the difference between the temperature of a heat medium (whether high or low) and the room temperature is constant by a method wherein the room temperature and the temperature of the heat medium are detected and the starting and stopping of the air conditioner are controlled on the base of the difference between the above mentioned temperature. CONSTITUTION:In an air conditioning arrangement in which the air conditioner 1 such as a fan coil unit arranged within the room is connected to a chiller or a heat source like a boiler through a pipe line including a circulation pump 3 and in case where hot water is supplied to the air conditioner 1 for heating, the temperature sensed by a hot water sensor 7 rises and the voltage at an output point A drops so that the temperature of the hot water is higher than the room temperature sensed by a room temperature sensor 6 by, for example, 10 deg.C and the voltage VA at the point A is lower than that at a point B, that is, VA

摘要： PURPOSE:To bring into the operation with large heat collecting effect by a method wherein the value of the temperature of heat carrier of a collector exceeding the fixed value is made into AND with the value of the difference exceeding the fixed value between the temperature of heat carrier of the collector and that of a heat accumulator so as to start a circulating pump. CONSTITUTION:When the detected temperature of a sensor 5 exceeds the fixed value, the potential at C becomes higher than that at A and as a result the output is generated from a comparator-amplifier 20 in a constant value thermocircuit 10 including a high temperature sensor 5 to detect the temperature of heat carrier of the collector. When the value of the difference of temperatures detected by sensors 5 and 6 exceeds the fixed value, the output is generated from a comparator-amplifier 24 in a difference value thermocircuit 11 which connects the high temperature sensor 5 with a low temperature sensor 6 to detect the temperature of heat carrier of the heat accumulator. The outputs of the both amplifiers 20 and 24 are inputted in an AND circuit 26 for AND, operation resulting in exciting a realy R to close a contact 30 in order to start the circulating pump 4.

摘要： PURPOSE:To bring into heat collecting operation only when the sun is shining by a method wherein the detected value of the sunlight exceeding the fixed value is made into AND with the value of the difference exceeding the fixed value between the temperature of heat carrier of a collector and that of a heat accumulator so as to start a circulating pump. CONSTITUTION:A light detecting element 20 to detect the sunlight, a high temperature sensor 7 to detect the temperature of heat carrier of the collector 1 and a low temperature sensor 8 to detect the temperature of heat carrier of the heat accumulator 2 are provided in a system in which the circulating pump 4 is provided in a piping 3 connecting the collector 1 with the heat accumulator 2. When the detected value of said light detecting element 20 exceeds the fixed value and the value of the difference between the detected temperatures of the both sensors 7 and 8 exceeds the fixed value, the both signals representing said values are made into AND to start the circulating pump 4.
