Regulating heating of single room, in hotel - using electronic control unit to operate electrically adjustable valves in hot water supply of respective radiators

摘要

At least two heating bodies or radiators (2, 3) supplied by the hot water circulation (6) of a central heating system (7) heat the room (1). The radiators are controlled separately by an electrically adjustable valve (8, 9) in the hot water supply (4) and electronic equipment (10), with means of entering working data and requirements and sensors (17), in particular for the room temperature. The equipment (10) produces control signals for the valves. In the outlets of the radiators (5) there is an additional sensor (12, 13) which gives a signal depending on the temperature of the hot water leaving a radiator and which is used by the electronic equipment to set the valves. The equipment from the signals of at least two sensors forms a reference signal, setting the valves so that the hot water leaving the radiators corresponds in temperature with that of the reference signal and so is the same at all radiators. ADVANTAGE - Improvement in control of heating process.
