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 ...
The Honeywell 200 was a character-oriented [1]: 70C-4S0-01n two-address commercial computer introduced by Honeywell in December 1963, [2] the basis of later models in Honeywell 200 Series, including 1200, 1250, 2200, 3200, 4200 and others, [3] [4] and the character processor of the Honeywell 8200 (1968).
Ventilation on the downdraught system, by impulsion, or the 'plenum' principle, applied to schoolrooms (1899) Natural ventilation is the ventilation of a building with outside air without using fans or other mechanical systems. It can be via operable windows, louvers, or trickle vents when spaces are small and the architecture permits.
Some of Honeywell's systems were minicomputers, such as their Series 60 Model 6 and Model 62 [28] [29] and their Honeywell 200. The latter was an attempt to penetrate the IBM 1401 market. In 1987, HIS merged with Groupe Bull, a global joint venture with Compagnie des Machines Bull of France and NEC Corporation of Japan to become Honeywell Bull.
Diagramatic operation of a thermal wheel Ljungström Air Preheater by Swedish engineer Fredrik Ljungström (1875–1964). A thermal wheel, also known as a rotary heat exchanger, or rotary air-to-air enthalpy wheel, energy recovery wheel, or heat recovery wheel, is a type of energy recovery heat exchanger positioned within the supply and exhaust air streams of air-handling units or rooftop ...
Demand control ventilation is an attractive alternative to standard design in these situations because DCV systems only supply the outdoor airflow necessary to serve the occupants in a space. Therefore, the above-described energy is not wasted in this system type.
