Variable air volume — (VAV) is a technique for controlling the capacity of a heating, ventilating, and/or air conditioning (HVAC) system. The simplest VAV system incorporates one supply duct that, when in cooling mode, distributes approximately convert|55|F supply air … Wikipedia
Constant air volume — (CAV) is a type of heating, ventilating, and air conditioning (HVAC) system. In a simple CAV system, the supply air flow rate is constant, but the supply air temperature is varied to meet the thermal loads of a space.[1] Most CAV systems are… … Wikipedia
Dedicated outdoor air system — A dedicated outdoor air system (DOAS) is a type of HVAC system that consists of two parallel systems: (1) a dedicated outdoor air ventilation system that handles latent loads and (2) a parallel system to handle sensible loads.[1] The graph on the … Wikipedia
building construction — Techniques and industry involved in the assembly and erection of structures. Early humans built primarily for shelter, using simple methods. Building materials came from the land, and fabrication was dictated by the limits of the materials and… … Universalium
