Building occupants similarly carry great expectations, that the HVAC system will function as intended. Chillers have become an essential HVAC component of a wide variety of commercial facilities, including hotels, restaurants, hospitals, sporting arenas, industrial and manufacturing plants, etc. The industry has long recognized that chiller systems represent the single largest consumer of electrical usage in most facilities.

Industrial water chillers are used in a variety of applications where chilled water or liquid are circulated through process equipment. Commonly used to cool products and machinery, water chillers are used in a multitude of different applications including injection molding , tool and die cutting, food and beverage , chemicals, lasers, machine tool, semi-conductors and more. The function of an industrial chiller is to move heat from one location usually process equipment or product to another place usually the air outside the manufacturing facility. Regardless of your industry and process, making sure that you have sufficient cooling is critical to productivity and cost savings.

Designing chilled water systems

Chapter Eight Chiller. Most commonly, they are absorption, centrifugal, helical rotary, and scroll. Some reciprocating chillers are also available. Chillers can be either air-cooled or water-cooled. Major vapor- compression chiller components include an evaporator, compressor s , condenser, and expansion device s Figure 1. Water-cooled chillers are typically installed indoors; air-cooled chillers are typically installed outdoors—either on the roof or next to the building. In cold climates, air-cooled chillers may have a remote evaporator inside the building for freeze protection.

A chiller is a machine that removes heat from a liquid via a vapor-compression , adsorption refrigeration , or absorption refrigeration cycles. This liquid can then be circulated through a heat exchanger to cool equipment, or another process stream such as air or process water. As a necessary by-product, refrigeration creates waste heat that must be exhausted to ambience, or for greater efficiency, recovered for heating purposes. Most common today are the hermetic scroll, semi-hermetic screw, or centrifugal compressors. The condensing side of the chiller can be either air or water cooled. Even when liquid cooled, the chiller is often cooled by an induced or forced draft cooling tower. Absorption and adsorption chillers require a heat source to function.

Regardless of whether the design is for a new chilled water CHW system or a modification to an existing system, an early review of codes, standards, and regulations is necessary to allow for an expedient design and avoid conflicts that will cost time and money to resolve. Local, state, and federal codes and regulations will dictate permitting requirements that affect the location of buildings and equipment central plants, cooling towers, buried piping systems , fuel handling and storage, environmental emissions and noise, water quality, and safety items. ASHRAE has numerous technical sources of information including a series of four handbooks that are updated every 4 years. This is very valuable for any designer or engineer beginning a new project, as these resources are updated every 3 or 4 years. This standard illustrates minimum efficiency and control systems requirements along with commissioning for building envelope, HVAC, power, lighting, and other equipment, all of which is included in a CHW system design. In a very broad sense, a CHW system consists of the following components:. For chillers using air cooling on the condenser side, there is no need for a condenser water loop including piping, cooling tower, and pump.

Many large buildings, campuses, and other facilities have plants that make chilled water and distribute it to air-handling units AHUs and other cooling equipment. The design, operation, and maintenance of these CHW plants has a very large impact on building energy use and energy operating cost. The intent of this course is to provide tools and guidance to engineers so that the plants they design have a near optimum balance of first costs and future operating costs. The course can also be used by plant operators to understand and resolve operational problems and improve energy efficiency through controls optimization. After completing the course, you should have an understanding of the following:.

Затем, в отчаянии, он поднял над собой левую руку, чуть не задев по лицу пожилого человека. Камера выхватила исковерканные пальцы Танкадо, на одном из которых, освещенное ярким испанским солнцем, блеснуло золотое кольцо. Танкадо снова протянул руку. Пожилой человек отстранился. Танкадо посмотрел на женщину, поднеся исковерканные пальцы прямо к ее лицу, как бы умоляя понять .

 Так посылал свои распоряжения Цезарь! - сказала Сьюзан.  - Количество букв всегда составляло совершенный квадрат. - Готово! - крикнула Соши. Все посмотрели на вновь организованный текст, выстроенный в горизонтальную линию. - По-прежнему чепуха, - с отвращением скривился Джабба.  - Смотрите. Это просто бессмысленный набор букв… Слова застряли у него в горле, глаза расширились.

 - Он пожал ее руку. - Примите мои поздравления, мистер Беккер.

 Так вы обратили внимание. - Конечно. Он работает уже шестнадцать часов, если не ошибаюсь. Чатрукьян не знал, что сказать. - Да, сэр.

 На пейджер, - повторил Джабба.  - Я думал, что… - Ладно, не в этом. В главном банке данных происходит нечто странное.
