Chilled Beam
A chilled beam is a type of Thermal radiation, radiation/convection HVAC system designed to heat and cool large buildings through the use of water. This method removes most of the zone sensible local heat gains and allows the flow rate of pre-conditioned air from the air handling unit to be reduced, lowering by 60% to 80% the ducted design airflow rate and the equipment capacity requirements. There are two types of chilled beams, a Passive Chilled Beam (PCB) and an Active Chilled Beam (ACB). They both consist of pipes of water (fin-and-tube) that pass through a heat exchanger contained in a case suspended from, or recessed in, the ceiling.Price, 2011, ''Engineer's HVAC Handbook'', p. 1067, ''2012 ASHRAE Handbook HVAC Systems and Equipment'', ASHRAE, 2012, p. 20.9, As the beam cools the air around it, the air becomes denser and falls to the floor. It is replaced by warmer air moving up from below, causing a constant passive air movement called convection, to cool the room.Hamilton ...

Thermal Radiation
Thermal radiation is electromagnetic radiation emitted by the thermal motion of particles in matter. All matter with a temperature greater than absolute zero emits thermal radiation. The emission of energy arises from a combination of electronic, molecular, and lattice oscillations in a material. Kinetic energy is converted to electromagnetism due to charge-acceleration or dipole oscillation. At room temperature, most of the emission is in the infrared (IR) spectrum, though above around 525 °C (977 °F) enough of it becomes visible for the matter to visibly glow. This visible glow is called incandescence. Thermal radiation is one of the fundamental mechanisms of heat transfer, along with conduction and convection. The primary method by which the Sun transfers heat to the Earth is thermal radiation. This energy is partially absorbed and scattered in the atmosphere, the latter process being the reason why the sky is visibly blue. Much of the Sun's radiation tra ...

Airbus UK
Airbus UK (formerly EADS UK) is a wholly-owned subsidiary of Airbus, based in the United Kingdom, which produces wings for Airbus aircraft. When Airbus (at the time known as EADS) was incorporated as a joint-stock company in 2001, BAE Systems transferred the British facilities of the transnational ''Airbus Industrie GIE'' consortium formed in 1970 to the new corporation in exchange of a 20% stake in it. These facilities, together, formed the entity called EADS UK. In 2006, EADS ended up acquiring BAE's 20% minority stake; EADS UK thus became a wholly-owned subsidiary of the company.
