What is CAV and VAV in HVAC || HVAC interview question answer in hindi ||

How does a Constant Air Volume system work? A CAV unit operates the fan and compressor at full capacity until the temperature drops to a specified setting, then the compressor turns off. The on/off cycling is not efficient at keeping the space at a constant temperature. CAV systems are small and serve a single thermal zone Where is CAV system used? Image result for what is constant air volume system CAV stands from Constant Air Volume. It's a type of HVAC air distribution system used in buildings where the volume of air suppled is kept constant but the temperature of the air is varied. What is a air volume system? Image result for what is constant air volume system Variable air volume (VAV) systems enable energy-efficient HVAC system distribution by optimizing the amount and temperature of distributed air. Appropriate operations and maintenance (O&M) of VAV systems is necessary to optimize system performance and achieve high efficiency. What is the difference between Constant Air Volume and variable air volume systems? Image result for what is constant air volume system Variable air volume (VAV) is a type of heating, ventilating, and/or air-conditioning (HVAC) system. Unlike constant air volume (CAV) systems, which supply a constant airflow at a variable temperature, VAV systems vary the airflow at a constant or varying temperature. Whats the difference between a CAV and a VAV? Ventilation systems can be classified into constant air volume (CAV) and variable air volume (VAV) systems, and this article will compare both types. CAV systems supply a constant airflow at variable temperature. VAV systems supply a variable airflow at constant temperature. What is a variable air volume system? What is a VAV system? VAV stands for Variable Air Volume. In its simplest form, VAV systems use varying airflow at a constant temperature to heat and cool buildings. This is opposite of a CAV (or Constant Air Volume) system, which supplies consistent air flow at varying temperatures to heat or cool a space. What is the difference between constant air volume and variable air volume control? Ventilation systems can be classified into constant air volume (CAV) and variable air volume (VAV) systems, and this article will compare both types. CAV systems supply a constant airflow at variable temperature. VAV systems supply a variable airflow at constant temperature What is a constant volume VAV? CAV systems keep a constant airflow, as their name implies, and the desired indoor conditions are reached by adjusting the air supply temperature. For example, when a building requires a higher cooling output on a hot summer day, the CAV system delivers colder air. VAV kya hota hai ? variable air volume kya hota hai ? CAV kya hota hai ?
