초록 ▼

An off-peak, electric, central air heating system for buildings incorporating a heat storage material that is used to store heat generated electrically during off-peak electrical power periods and to deliver heat on demand. The heat storage material is an alkaline metal or alkaline earth metal salt such as Na2SO4, NaCl, CaCl2 and KCl individually or in combination with one another. Generation of heat during the off-peak electrical power periods is automatically controlled by an electronic time clock and time delay circuitry, and by selective variable temperature control. The heating unit is constructed with a casing having an inner jacket and an outer jacket with an air space between the two jackets. The storage material is surrounded by the inner jacket and the air space provides insulation as well as an air passage between the two jackets. The transfer of heat from the heat storage tank into the building at desired temperature is achieved by a proportional air flow control device and a two speed fan. When air is directed only through the space between the two jackets, the fan runs at low speed. When air is directed through the inner jacket containing the heat storage material, the fan runs at high speed. Also disclosed are emergency override as well as other control circuits that operate on timed as well as temperature bases to insure proper heating of the space.

An electrical heating unit comprising: a mass of solid heat storage material for storing heat generated electrically during off-peak electrical power periods; means associated with the mass of solid heat storage material for electrically generating heat for storage in the heat storage material; a casing having an outer jacket and an inner jacket with an air space therebetween, the heat storage material being enclosed in the inner jacket; means associated with the solid mass of heat storage material for withdrawing heat stored in the mass of solid heat storage material, said heat withdrawing means including an air inlet passage communicating with the air space between the inner and outer jackets and with the interior of the inner jacket; and an air outlet passage communicating with the space between said inner and outer jackets with the interior of said inner jacket; a two-speed fan disposed to draw air into said air inlet passage; an air flow control gate in one of said air passages, the air flow control gate being movable to select the path of air flowing from said inlet air passage to said outlet air passage, control means for moving said gate to selectively direct the air driven by the fan in one of three manners including (1) only through the air space between the two jackets, (2) only through the interior of the inner jacket thereby causing the air to pick up heat directly from the mass of solid heat storage material and (3) in two parts with one part being directed through the air space between the two jackets the other part being directed through the interior of the inner jacket, the two air parts being subsequently blended together in said air outlet passage for delivery to a space to be heated; and means for controlling operation of the fan between its two speeds, said fan control means being responsive to the position of said air flow control gate and operating said fan on the lower of its two speeds when the air flow control gate is set to allow air flow only through the air space between the jackets and operating the fan on the higher of its two speeds when the air flow control gate is set to allow air flow other than only through the air space between the jackets.
