LonWorks or Local Operating Network is an open standard (ISO/IEC 14908) for networking platforms specifically created to address the needs of control applications. The platform is built on a protocol created by Echelon Corporation for networking devices over media such as twisted pair, power lines, fiber optics, and wireless.
A thermostat exerts control by switching heating or cooling devices on or off, or by regulating the flow of a heat transfer fluid as needed, to maintain the correct temperature. A thermostat can often be the main control unit for a heating or cooling system, in applications ranging from ambient air control to automotive coolant control.
In the 1990s, Carrier stopped using the "Day & Night" brand (which was the "D" in the BDP division, or Bryant-Day & Night-Payne) but it was revived in 2006 by ICP. In 2001, Carrier was the "world's largest manufacturer of air-conditioning, heating, and refrigerator equipment" with a "total employment of 42,600" and a revenue of $8.9 billion.
A thermostatic radiator valve on position 2 (15–17 °C) Installed thermostatic radiator valve with the adjustment wheel removed A thermostatic radiator valve (TRV) is a self-regulating valve fitted to hot water heating system radiator, to control the temperature of a room by changing the flow of hot water to the radiator.
The thermostat controls the fan speed and/or the flow of water or refrigerant to the heat exchanger using a control valve. Due to their simplicity, flexibility, and easy maintenance, fan coil units can be more economical to install than ducted 100% fresh air systems (VAV) or central heating systems with air handling units or chilled beams .
They may be as simple as an off/on thermostat or as complex as a building automation system using BACnet or LonWorks, for example. Common control components include temperature sensors, humidity sensors, sail switches, actuators , motors, and controllers.
BACnet is a communication protocol for building automation and control (BAC) networks that use the ASHRAE, ANSI, and ISO 16484-5 standards [1] protocol.. BACnet was designed to allow communication of building automation and control systems for applications such as heating, ventilating, and air-conditioning control (), lighting control, access control, and fire detection systems and their ...
The International S series is a range of trucks that was manufactured by International Harvester (later Navistar International) from 1977 to 2001.Introduced to consolidate the medium-duty IHC Loadstar and heavy-duty IHC Fleetstar into a single product range, the S series was slotted below the Transtar and Paystar Class 8 conventionals.
