Computerized controls do more than reduce energy costs.Managers and condo and co-op boards are confirming the experience of private landlords who have found that computerized computerized adapted for analysis, storage and retrieval on a computer. computerized axial tomography see computed tomography. controls originally installed to conserve energy and water are also substantially reducing the cost of maintaining heating and hot water systems. Hot Water Problems Domestic hot water temperatures can be misdiagnosed with the result that mixing valves and coils, which can cost thousands of dollars, often are needlessly need·less adj. Not needed or wished for; unnecessary. need  less·ly adv.need replaced. By monitoring the temperature of the water in the boiler boiler, device for generating steam. It consists of two principal parts: the furnace, which provides heat, usually by burning a fuel, and the boiler proper, a device in which the heat changes water into steam. and the water coming out of the hot water coil, the U.S. Energy computerized control indicates if mixing valves or coils actually require replacement. The computerized control also provides the option of automatically raising the boiler water temperature during peak demand periods when the coil can't keep up with domestic hot water usage. The control also can automatically lower the boiler water temperature during off-peak periods for fuel saving. System Balance In order to achieve correct heat balance in all the apartments in a multifamily building, it is important to install indoor temperature sensors in every top-floor apartment. These sensors enable the U.S. Energy computerized control to determine if heat is balanced throughout the building. Consider the case of a building with more than 20 top-floor apartments. The computerized control may show that the.apartments located in the center portion of the floor - i.e., those located more or less directly above the boiler - are adequately heated, but those on the outside corners are not getting sufficient heat, which may indicate that all the outside apartments in lower floors that are served by the same risers have the same problem. Often, there is no need for expensive plumbing plumbing, piping systems inside buildings for water supply and sewage. The Romans had a highly developed plumbing system; water was brought to Rome by aqueducts and distributed to homes in lead pipes—hence the name plumbing from the Latin word plumbum work on the risers. The problem can be solved by replacing radiator radiator, device used to heat an area surrounding it or to cool a fluid circulating within it. The familiar radiators of steam and hot water heating systems in buildings are misnamed, as they operate principally by convection, in which heat is transferred by air air valves a valve to regulate the admission or egress of air; esp. a valve which opens inwardly in a steam boiler and allows air to enter. etc. See under Air. Ball, Check, etc. See also: Air Valve in cold apartments with valves of a larger size. based on computerized monitoring of apartment temperatures during all weather conditions, many savvy managers have insulated in·su·late tr.v. in·su·lat·ed, in·su·lat·ing, in·su·lates 1.

Condensate condensate, matter in the form of a gas of atoms, molecules, or elementary particles that have been so chilled that their motion is virtually halted and as a consequence they lose their separate identities and merge into a single entity. Return Line Leaks Hidden leaks in a condensate return line can be responsible for wasting thousands of gallons of water in a 24-hour period. Moreover, a leak may be so bad that a boiler cannot make steam. Leaks may not be noticed if return lines are buried deep under a concrete basement floor and/or remotely located. Also, the leaks can go undetected because the boiler water is automatically replenished with new cold water or manually replenished by a building superintendent A building superintendent or building supervisor (often known simply as the super) is a manager responsible for repair and maintenance in a residential building. They are the first point of contact for residents of the building. . This cold water must be reheated, which wastes fuel. A U.S. Energy computerized control can detect these leaks promptly and indicate the need for repairs. Stack Cleaning Computerized monitoring of stack temperatures makes it unnecessary to go to the expense of cleaning boilers on a regularly scheduled basis. If the stack temperature is in the normal range, the boiler does not need cleaning. Technical Support An increasing number of managers are turning to the suppliers of computerized energy management systems to help them identify heat and hot water system maintenance problems that require immediate attention. U.S. Energy Controls, which manufactures, installs and supports these systems in the New York Metropolitan area New York–Northern New Jersey–Long Island is the most populous metropolitan area in the United States and the third most populous in the world, after Tokyo and Mexico City. , has responded to this need with a weekly report called The Boilergram.

The Boilergrams, which consist of customized recommendations for each building, are uploaded to a PC at each management firm. The technical staff is available to provide all the support needed to implement these recommendations. |
