CONTROLLING METHOD OF HOT WATER SUPPLY SYSTEM IN SOLAR ENERGY AIR CONDITIONING AND HOT WATER SUPPLY SYSTEM

摘要

PURPOSE:To reduce useless calorie of an auxilary heater by a method wherein a timer setting a use time band of a special hot water supply load such as bath and showers as well as another timer setting the drive time band ov an anuxilary heater directly before the set time band is controlled. CONSTITUTION:When the temperature of a hot water storage tank 6 reaches the use setting temperature of a hot water supply load 8, a full signal t2 of the ''1'' level is output from a sensor T2 for detecting the hot water storage tank temperature and the signal t2 is inverted through an inversion circuit NOT2 to become the ''0'' level, as a result, it is not output, thus, a driving signal 7' of a pump 7 is not obtained. When the signal t2 is not output, a difference temperature signal of the ''1'' level is output from a difference temperature detector T1 and at the same time, the temperature of a heat medium of a high temperature storage heat tank 3 exceeds a set value or more. And either when a heat medium effective temperature signal T5 of the ''1'' level is output from a sensor T5 for detecting the heat medium temperature or when a use time band singal TM1 of the hot water supply load 8 and a drive time band TM2 of a heater 9 are not output, a signal is output from an AND circuit AND2, thus, the driving signal 7' of the pump 7 is output from an amplifier AMP3.
