11 Table terms explained 'Sydney tubes': Another term for the most common of evacuated tubes. Named after the Solar Energy Research Group at the University of Sydney as they developed an all-glass evacuated tube for solar s which has become the industry standard design. Closed loop: Also called a d circuit or indirect, d loop s use a heat exchanger in the tank which is to the s. Heat transfer fluid circulates between the solar s and the heat exchanger, transferring the heat to the potable water in the tank. The heat transfer fluid and the water are never in contact. Closed loop s may use water in the d loop, but normally use low freezing point liquids such as propylene glycol, especially if installed in frost-prone areas. Closed loops may be used in both - and split s. Open loop: Also called direct s, open loop s have the s directly to the tank. The potable water in the tank flows between the tank and the s and is itself the heat transfer fluid. Direct s are not usually used in frost-prone areas due to the risk of water freezing in the s. Drainback : A using an unpressurised d loop where there is an air space in the loop and a small reservoir for the heat transfer fluid. Heat transfer fluid (usually pure water) is pumped to the s where it is heated and drains back under gravity. Drainback s have some advantages over other d loop s they can prevent overheating simply by turning off the circulating pump. The same applies for freeze. Their main disadvantage is that the pump will use more energy compared to a regular d loop as it has to overcome gravity to push water up to the. Some drainback s may even have two pumps, the second circulates potable water from the main tank to the HTF tank's heat exchange coil for heating. Borosilicate: A of heat-resistant glass, commonly used in applications that require low thermal expansion and high strength characteristics, such as solar water heater tubes, laboratory glassware etc. Its primary constituents are silica (silicon dioxide) and boron trioxide. U-tube: A tube, usually found inside solar thermal evacuated tubes, in which the water to be heated flows directly. So-named because the tube is a double tube with a U-bend at the end, so that water flows first one way along the length or the tube, and then back again. Nichrome: An electrical wire made primarily from chromium and nickel, designed to have a particular resistance per unit length and mostly used to make heating elements. The most common form of resistance wire. Selective surface: A surface coating that increases solar absorption while decreasing heat emission. Used to make solar s more efficient. Absorbing area: When used in reference to a solar thermal, it refers to the actual area of that absorbs the sun's rays, as opposed to the total area of the. For example, the space between tubes in an evacuated tube does not absorb heat, only the tubes do. So a 's absorbing area will be smaller than the physical size taken up by the complete. Polyamide: In relation to appliances, a form of tough plastic. Nylon is one example of a polyamide. Stainless /vitreous lined : s are usually either stainless (may be grade 30 or the more corrosion resistant grade 316), which has a minimum of 10.5% chromium by mass, or vitreous lined, which is regular with a coating, similar to glass, which is literally melted onto the to form a corrosion-resistant lining. STCs: Small-scale technology certificates are a form of rebate (available across Australia) for installations of renewable energy technologies each STC is equivalent to the one megawatt hour of electricity the will displace over a 10-year period. STCs can save you a great deal on the cost of a new heat pump or solar thermal hot water. The STCs are usually arranged by the supplier so you don t need to do any paperwork to receive the discount. Prices stated in these tables are pre-stcs, so actual cost will be lower, depending on your location and the installed. Sputtering: a method of applying a thin-film coating to a surface by eroding a piece of 'target' such that the emitted during erosion deposits on the surface to be coated.
