摘要:
A heat storage apparatus for a conventional electrical baseboard-mounted heater requires no modification of the heater and provides means for supporting, storing heat within and circulating electrically-heated air through blocks of heat retaining material and an easy method of conversion to such form.
摘要:
A heat storing fireplace including a fire-box surrounded by a heat storage medium which is either an enclosure containing a material having a high specific heat such as sand or gravel or a large number of heat conducting bags containing a high specific heat material. Exhaust gases are conveyed from the fire-box to an exhaust outlet by several conduits extending through the heat storage medium in a circuitous path in order to transfer heat from the exhaust gases to the heat storage medium. Heat is further distributed through the storage material by a heat conducting lattice fastened to the conduits and extending through the storage medium in a circuitous path. Combustion air enters the bottom of the fire box through a combustion air inlet jacket surrounding the exhaust outlet in order to simultaneously pre-warm the combustion air while thermally insulating the exhaust outlet from its support structure. A draft is created through the fire-box by an exhaust fan mounted in the exhaust outlet. Although the heat storage medium is primarily heated by burning fuel in the fire-box, it may also be heated by either an electric grill or solar heat exchanger embedded in the heat storage medium. The upper portion of the storage medium is covered by a ventilating plenum which allows heat to escape from the enclosure. The plenum has a pair of ventilated sidewalls separated from each other by a baffle. A fan, which may be thermostatically controlled, is positioned in an opening in the baffle in order to selectively produce air flow through the plenum. Heat in the storage medium may also be utilized by placing a hot water heating heat exchanger in the storage medium.
摘要:
An electric heat accumulator unit for use in an electrically powered motor vehicle characterized in that the unit is powered independently of the battery used to power the vehicle. The unit makes use of an accumulator which is adapted to store therein heat generated by an electric heating means operatively associated with the accumulator and energized from an external power supply. A blower is provided to circulate air through passages in the accumulator for extraction of heat therefrom. A blower is provided to circulate air through passages in the accumulator for extraction of heat therefrom. The blower may be powered by means of a thermoelectric power source in heat exchange relationship with the accumulator. A voltage regulator is provided to maintain a constant voltage from the thermoelectric power source. A temperature responsive circuit varies the blower speed as the temperature of the accumulator changes in order to maintain a substantially constant thermal output from the accumulator.

A high-temperature heat exchanger comprises a thermally insulated solid body formed from a high temperature resistant material with a thermal conductivity of at least 20 W/mK, at least one heater element within the solid body; and passages for fluid flow formed in the solid body. A system is also disclosed that comprises high-temperature heat exchanger in a thermo-management circuit of a battery.
摘要:
A method and apparatus of controlling the electric power usage of electric thermal storage heaters and systems are based on: 1) current and recorded measurements local to the heater and building; 2) current measurements external to the heater and building; 3) forecasts communicated to the apparatus. The method also includes sending out communications about power use as well as various other local measurements. The apparatus has local controls on the electric thermal storage, including but not limited to the relays that control flow of power into the heating elements, a logic module that integrates the local controls, as well as communication channels that extend outside the building to entities capable of providing automatic forecasts and potentially other types of information not available locally.
