This paper presents an advancement in HVAC system analysis, which is predicated on the electrical analogy to fluid systems. An integrated description or a building's HVAC system and rooms is constructed and may be used to support system testing and balancing, system performance analysis, capacity verification testing, and room interactions. Additional system simulation is useful to assess plant modifications and their impact on HVAC performance. This method is applicable to any facility with a large or complex HVAC system configuration.
The Equitable Building, which opened on 1January1948, in Portland, Oregon, was the first of a new architectural form. Technically and aesthetically it was radically different from any previous structure. It was a fully air conditioned building, clad with sheer aluminium curtain walling and huge expanses of sea green tinted sealed glass. It was fully electric with heat pumps providing heating and cooling from underground aquifers. The architect was Pietro Belluschi, an Italian immigrant who originally trained as an engineer and the mechanical engineer was J.
This paper aims to outline the current state-of-the-art in integrated building simulation for performance prediction of heating, ventilating and air-conditioning (HV AC) systems. The ESP-r system is used as an example where integrated simulation is a core philosophy behind the development. The current state and future developments are illustrated with case studies. It is argued that for building simulation to penetrate the profession in the near future, there is a need for appropriate training and professional technology transfer initiatives.
During the last fifty years air condition i ng has become commonplace in commercial buildings and, in this time, we have managed to generate a poor image, both in the press and among the people who occupy air conditioned buildings. How have we succeeded in turning what people in hot countries regard as a blessing into a target for criticism and even abuse?
Until the late 1950s, virtually no firms specialized exclusively in testing, adjusting, and balancing the components of heating, ventilating, and air-conditioning (HVAC) systems. The balancing, if performed at all, was done by the HVAC contractor, who lacked the necessary expertise required for advanced testing and balancing. After installation, many design engineers found that their systems were not working, not because of flawed design but because of improper balancing or deficient performance of the equipment.
