Embodiment Construction

[0026] As mentioned earlier, there are various energy sources (such as solar energy, electricity, oil, gas, and wind, etc.) that can only be harvested for a limited time within a 24-hour day. This is in contrast to the demand for electrical, heating or cooling power associated with a residential or commercial building, which can vary in any given 24-hour period. The open ATESS accommodates the limited availability of these energy sources, providing a stable source of energy required throughout the 24 hours.

[0027] refer to figure 1 , ATESS1 is shown installed in an underground area 2 of a residence with an oil or gas stove system 4 . The ATESS 1 may include a storage tank 6 containing some thermal energy storage material 8, a hot water storage tank 10 for heating and distributing hot water through the dwelling, and a hot water storage tank 10 between the storage tank 6 and the furnace system 4. , a connecting piece 12 for realizing the heat transfer between the thermal ene...

Abstract

The invention discloses an active thermal energy storage system which uses an energy storage material that is stable at atmospheric pressure and temperature and has a melting point higher than 32 degrees F. This energy storage material is held within a storage tank and used as an energy storage source, from which a heat transfer system (e.g., a heat pump) can draw to provide heating of residential or commercial buildings and associated hot water. The energy storage material may also accept waste heat from a conventional air conditioning loop, and may store such heat until needed. The system may be supplemented by a solar panel system that can be used to collect energy during daylight hours, storing the collected energy in the energy storage material. The stored energy may then be used during the evening hours to heat recirculation air for a building in which the system is installed.

Description

technical field [0001] The present invention relates to a system for heating and cooling residential and commercial building spaces and a hot water system, in particular to an active heat exchange system for efficiently controlling air and water temperatures in commercial buildings and residential buildings. Background technique [0002] The U.S. generation and distribution network is currently under pressure from curtailment during daytime peak demand. The requirements for air conditioning and water heating in the industrial sector, commercial and residential are expected to be highest during the daytime. During off-peak hours, ie in the evening and late at night, the situation is reversed and there is usually excess power available which is not needed in the local grid. [0003] Utilizing nationwide transmission power lines, the generation and distribution grid is used to transmit additional power to other grids that require it. This is a form of load balancing whose pur...
