Definitions
- the method applied to control their operation is based on the Heater (4) built-in in their structure, heating the water up to desired temperature and powered by electric main through in serial connected a Thermal electric cutout (2) and a Thermal controller (3).
- the heating process starts in T x time (Fig.l) in current water temperature t ⁇ , coincident with T 2 boiler switch on time and lengthens up to reaching maximum water temperature t m , adjusted by means of the thermal controller.
- the line “a” is the theoretical heating curve with no thermal losses, and the line “b” is the real curve accounting the thermal losses.
- the S x areas are the thermal losses for the T x -T period.
- T p - a time of hot water consumption. Duration of the heating process is variable and it depends on: the heater power; the water temperature within the reservoir in initial heating time;boiler thermal isolating properties; ambient temperature;
- the electric boiler operation in ON/OFF mode posses the following negative sides: a) irreparable energy loss - the thermal radiation in environment is to the highest degree because of water temperature is held up by the thermal controller to values, close to the maximum and in a period when hot water isn't consumed; b) the frequent and unbroken for long periods thermal controller turns on/off damage it quickly too (whereupon cases of boiler explosions are recorded) and the repair-to-repair periods are shorted; c) starting boiler operation more before period where the hot water would be consumed.
- the essence of the proposal is consist in that to propose a new method controlling volumetric electric storage boilers operation enabling them to operate in delaying mode.
- the method is based on the possibility the heating process to be shifted in time in such manner that heating to be independent on switching on time and to finish in time when starting heat water consumption is expected.
- a controller unit is added-in into the boiler design, which enables: - to watch in-boiler water current temperature in continuous mode;
- the heater 3 powered by electric main through con- troller unit 2 heats water up to desired temperature.
- the essential in this case is that the method, by the controller unit, enables in arbitrary time T 2 (Fig.2) wanted later time T to be fixed, which is start of hot water consumption in such manner that the T x time of start of hot water consumption to start when the time T 3 needed for reaching the water temperature defined by the thermal controller to synchronize to the T n time, when the hot water will start to be consumed.
- thermocouple 2 feeding data about current water te pera- ture to the adjustable controller 3, is mounted on the boiler's water reservoir 1.
- the test lamp 4 lights when voltage is applied by switch 8.
- the display 5 shall be reset by button 7, and desired time, when hot water would be consumed, shall be adjusted by buttons 9 and 10;
- Voltage is applied to the controller by turning on switch 8, then the test light indicator 4 is energized; In this position, the controller doesn't feed voltage to the heater 12; - On the next day only, the controller, receiving by the thermocouple 2 data for boiler water current temperature, shall switch on and apply voltage to the heater in such time that the heating process to finish in 13.00 o'clock. This switch on time and heating duration (usually 1-3 hours) depend very much on residual stored energy from previous boiler turnings on and heater 12 power.
