1.2.24 Installation of thermostatic radiator valves Description These elements open and close automatically the flow of hot water in radiators and fancoils, depending on the temperature selected by the user. To install thermostatic valves, the heating circuit should be leaked out and the shut-off valve should be replaced by a thermostatic valve. [...]
2.4.1 Installation of program warm-start ballast Description Program warm-start ballasts incorporate a precise starting sequence to turn on a lamp while minimizing lamp filament wear. Benefits These ballasts enable lamps to last about 100,000 switching cycles, whereas instant-start ballasts enable lamps to last only 10,000-15,000 switching cycles Programed warm-start [...]
2.4.2 Installation of electronic ballast Description Electrical ballast is a device whose aim is limiting the amount of current that passes through a discharge lamp during the start-up. First, they provide the necessary voltage to start up the lamp and after that they limit the current. Lamps that use ballast are halogen lamps, [...]
2.4.3 Replacement of conventional halogen lamps by Infrared Reflective Coating (IRC) halogen lamps Description The innovative IRC technology increases the efficiency of halogen lamps by reflecting a major part of the generated useless IR radiation back to the coil where it is converted into visible light. The infrared reflective coating at the outside [...]
2.4.4 Replacement of incandescent lamps by Compact Fluorescent Lamps (CFLs) Description In a CFL, an electric current is driven through a tube containing argon and a small amount of mercury vapor. This generates invisible ultraviolet light that excites a fluorescent coating (called phosphor) on the inside of the tube, which then emits visible [...]
2.4.5 Installation of Lighting Emitting Diode (LED) lamps Description Light in an LED is emitted by a solid, rather than a gas object as it is the case of the fluorescent tubes. The LED is a semiconductor diode that emits light when it is crossed by an electric current. Wavelength of the [...]
2.4.6 Replacement of fluorescent tubes by others with less diameter Description The most commonly used fluorescent lamps today are the T8 (ø 26 mm). However, the T5, (ø 16 mm) which only work with auxiliary electronic equipment, have been developed. This, along with its minor diameter provides a high luminous efficiency, which can [...]
2.4.7 Replacement of standard fluorescent tubes by triphosphorous fluorescent tubes Description Lamps that contain the next generation of phosphors offer improvements in efficiency as well as very good colour rendering. Benefits Provide between a 12 and 15% more light Longer lifespan (around 12,000-19,000 hours) Better light quality Less mercury [...]
2.4.11 Installation of manual potentiometer switches Description It is a high frequency push/rotatory or slide dimmer switch. The DC supply can be increased or decreased by the switch to affect the resistance, hence the dimness of the lamp. This form of dimming requires a dimming pair of cables to be run around [...]
2.4.13 Installation of daylighting sensors (on/off) Description It is a system that automatically adjusts the quantity of light emitted by the lamp according to the contribution of natural light in the area where it is located. The lamps are connected/disconnected automatically to detect a level of determined brightness (they are turned on [...]
