Roberts-Gordon LLC
Roberts-Gordon LLC is an international manufacturer of HVAC equipment, controls and associated accessories. The company is best known for introducing the first commercially produced gas-fired, low-intensity infrared product, CORAYVAC, into the heating industry. Roberts-Gordon LLC was also the first company to patent fully modulating infrared systems with an ULTRAVAC control, a control that allowed building owners to modulate burner input rate with outdoor air temperature in order to match the heating system’s input to the building’s heating requirement. Multiple heating systems throughout the country were then able to be monitored from a single desktop.Products. LP/Gas. Volume 6, Issue 8. EBSCO Publishing, United States. 2003. p. 26.

HVAC
Heating, ventilation, and air conditioning (HVAC) is the use of various technologies to control the temperature, humidity, and purity of the air in an enclosed space. Its goal is to provide thermal comfort and acceptable indoor air quality. HVAC system design is a subdiscipline of mechanical engineering, based on the principles of thermodynamics, fluid mechanics, and heat transfer. "Refrigeration" is sometimes added to the field's abbreviation as HVAC&R or HVACR, or "ventilation" is dropped, as in HACR (as in the designation of HACR-rated circuit breakers). HVAC is an important part of residential structures such as single family homes, apartment buildings, hotels, and senior living facilities; medium to large industrial and office buildings such as skyscrapers and hospitals; vehicles such as cars, trains, airplanes, ships and submarines; and in marine environments, where safe and Sick building syndrome, healthy building conditions are regulated with respect to temperature and ...

Infrared Heater
An infrared heater or heat lamp is a body with a higher temperature which transfers energy to a body with a lower temperature through electromagnetic radiation. Depending on the temperature of the emitting body, the wavelength of the peak of the infrared radiation ranges from to 1 mm. No contact or medium between the two bodies is needed for the energy transfer. Infrared heaters can be operated in vacuum or atmosphere. One classification of infrared heaters is by the wavelength bands of infrared emission. * Short wave or near infrared for the range from to ; these emitters are also named "bright" because still some visible light is emitted; * Medium infrared for the range between and ; * Far infrared or dark emitters for everything above . History German-British astronomer William Herschel, Sir William Herschel is credited with the discovery of infrared in 1800. He made an instrument called a spectrometer to measure the magnitude of radiant power at different wavelengths. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
