  2. Ice storage air conditioning - Wikipedia

    en.wikipedia.org/wiki/Ice_storage_air_conditioning

    Illustration of an ice storage air conditioning unit in production. Ice storage air conditioning is the process of using ice for thermal energy storage. The process can reduce energy used for cooling during times of peak electrical demand. [1] Alternative power sources such as solar can also use the technology to store energy for later use. [1]

    Central, "all-air" air-conditioning systems (or package systems) with a combined outdoor condenser/evaporator unit are often installed in North American residences, offices, and public buildings, but are difficult to retrofit (install in a building that was not designed to receive it) because of the bulky air ducts required. [32] (Minisplit ...

    This is a high-power, high-frequency phased array radio transmitter with a set of 180 antennas, disposed in an array of 12×15 units that occupy a rectangle of about 30–40 acres (12–16 hectares). [ 30 ] [ 31 ] The IRI is used to temporarily energize a small portion of the ionosphere .

  5. HVAC control system - Wikipedia

    en.wikipedia.org/wiki/HVAC_control_system

    HVAC (Heating, Ventilation and Air Conditioning) equipment needs a control system to regulate the operation of a heating and/or air conditioning system. [1] Usually a sensing device is used to compare the actual state (e.g. temperature) with a target state. Then the control system draws a conclusion what action has to be taken (e.g. start the ...

    International Reference Ionosphere (IRI) is a common permanent scientific project of the Committee on Space Research (COSPAR) and the International Union of Radio Science (URSI) started 1968/69. It is the international standard empirical model for the terrestrial ionosphere since 1999.

  7. Ground-coupled heat exchanger - Wikipedia

    en.wikipedia.org/wiki/Ground-coupled_heat_exchanger

    A key aspect of earth-air heat exchangers is the passive nature of operation and consideration of the wide variability of conditions in natural systems. Earth-air heat exchangers can be very cost effective in both up-front/capital costs as well as long-term operation and maintenance costs.
