Book excerpt: HVAC (heating, ventilation, and air conditioning) controls and sensors are devices used to regulate the temperature and air quality of indoor spaces. They are used in a variety of settings including residential, commercial, and industrial buildings. HVAC controls and sensors work together to provide a comfortable and safe environment for occupants. The main components of HVAC systems are the thermostat, which measures and regulates the temperature, and the air handler, which is responsible for circulating and conditioning the air. HVAC controls and sensors are also used to monitor humidity levels and to adjust fan speeds in order to maintain the desired comfort level. HVAC controls and sensors can be manual or automated. Manual controls are typically operated by a thermostat, while automated controls are operated by a computer or other intelligent device. Automated controls can be used to program temperature levels and set times for the system to turn on or off. In addition to temperature and air quality, HVAC controls and sensors are also used to monitor energy consumption. This is done by measuring the amount of electricity used by the system and adjusting the fan speed accordingly. This can help to reduce energy costs by ensuring that the system is only running at the necessary level.

Download or read book HVAC Instrumentation and Control written by A. Bhatia and published by CreateSpace. This book was released on 2014-12-01 with total page 134 pages. Available in PDF, EPUB and Kindle. Book excerpt: The HVAC systems are designed for peak conditions. Because these conditions prevail only for small period in a year, the HVAC equipment must operate most of the time at lean capacity. The function of the control system is to adjust the equipment capacity to match the load. Automatic controls are necessary not only to achieve the design conditions in the conditioned space but are also required for efficient operation of the HVAC system. The main parameters to be controlled in air conditioning system are temperature, pressure, humidity, air quality and thermal energy distribution. This 6 -hour quick book covers the basic control fundamentals of automatic controls in the HVAC system. Emphasis is placed on the control principles, terminology, basic components, control devices and direct digital control systems.
