Abstract (en)

[origin: EP0826934A1] During discharge, heat transfer rate depends on fan speed, controlled by altering the fan motor voltage. A thermostat monitoring the ambient temperature cuts the fan(s) out at the applied setting (Tc), and in at a slightly lower value (Tl). As temperature recovers (AB), fan motor voltage is raised from 170 in 3x20v steps, each lasting 5 minutes, the final step being extended if necessary to achieve the set level (Tc). If the tariff so provides, a continued fall (AE) to a lower temperature (T2), above the overnight setting (T3), is countered by partial re-energising of the heater elements. Each night's charge is determined according to the percentage charge remaining the previous evening, as calculated from fan running times and speeds.
