Abstract

PURPOSE:To minimize an electric power for melting by a constitution wherein a preparatory period is divided into a plurality of time zones and a corresponding preparatory period zone is selected on the basis of the relationship between a room temperature and a set temperature so as to control a time of electrification in the titled heater utilizing a large latent heat material. CONSTITUTION:A preparatory period for a heater, e.g. a period of 2:00a.m.- 8:00a.m., is divided into three periods, i.e. 2:00-4:00, 4:00-6:00 and 6:00-8:00, and timers 13A-13C are made to correspond with these periods respectively, while a room temperature in an initial stage of the preparatory period or a temperature corresponding therewith is compared with the maximum, minimum and middle set temperatures 14A-14C to set the timers 13A-13C respectively. By this constitution, temperature controllers 14A-14C with minimum thermometers are made to operate at the room temperature to charge the corresponding timers 13A-13C. A relay 12 is closed in prescribed time zones by the timers thus operated, a heater 2 is electrified by a power source 10, and thereby a latent heat material is melted for regeneration. By this constitution, a required electric power can be minimized.

The latent heat of the Glauber's salt is about 42°C, and when it is used as a heat storage material for the floor heating, it can be completely melted by heating it with electricity until it reaches the melting point or a temperature slightly higher than this. When doing so, the amount of heat released at a constant temperature is large and gradually dissipates, so the indoor temperature must be maintained at the desired comfortable temperature (for example, around 22°C) for a long time (for example, about 10 hours) even after the power is turned off. be able to.

For this reason, when heating inside a building, the heater is energized at night when the room is not in use to melt the heat storage material in advance, and during the day when the room is in use, the power is turned off to release the heat that solidifies (mainly).
A widely used method is to maintain the room temperature at a desired comfortable temperature. This method of use is also extremely economical in that heating can be done at night, when electricity demand is low and electricity rates are low (approximately one-third of daytime rates in Japan).

By the way, the conventional method of energizing a regenerative electric heater as described above is to set a certain preparation period in advance (for example, from 2:00 a.m. to 8:00 a.m.) during the time when the night rate is applied, and then to adjust the temperature and The energization is started at the beginning of this preparation period regardless of the outside temperature, and when the heat storage material reaches the upper limit set temperature which is higher than the melting point, the thermistor turns off the energization, and at the end of the preparation period (the usage period, i.e. the heating period). Until the beginning, the method used was to keep the heat storage material at a predetermined temperature using a thermostat.

The graph in FIG. 1 shows a case where the preparation period is set from 2:00 a.m. to 8:00 a.m., and energization of the heater is started at the beginning of the preparation period (2:00 a.m.). In addition, in order to prevent the temperature of the heat storage material from rising significantly beyond its melting point,
In other words, in order to prevent an excessive rise in sensible heat in the heat storage material, the power supply to the heater is controlled by a thermostat that operates at a predetermined temperature.The operating point of this thermostat is set at approximately 30°C in the graph of Figure 1. F in FIG. 1 indicates the energized state in that case.

In the conventional control method of the latent heat type electric heater explained above with reference to Fig. 1, the setting is fixed regardless of the room temperature or the corresponding temperature (floor temperature, heat storage material temperature, etc.). Since electricity is started at the beginning of the preparation period (2 o'clock), even after the heat storage material has melted, the thermostat must be operated to keep the heat storage material at a predetermined temperature until the end of the preparation period. However, it has the disadvantage of wasting electricity to keep it warm. In particular, if the room temperature is not too low and the heat storage material melts early, the heat retention period becomes longer and the proportion of power consumption required for heat retention increases.

As is clear from the graphs in Figures 1g4 to 7, according to the heater energization control method according to the present invention, room temperature or a temperature corresponding thereto (floor temperature, heat storage material temperature, etc.)
is detected, and based on the detected value, the minimum necessary energization time is set so that the heat storage material reaches a molten state with sufficient latent heat at the end of the preparation period (preferably coincident with the beginning of the use period as in the example). Therefore, unnecessary power consumption can be eliminated and economical heating operation can be performed. At the same time, since the heating time can be minimized and the number of switching operations can also be minimized, the durability of the heater can be improved.
