• Basic Information About Portable Air Conditioners
  Source: http://www.listfree.org/37579-basic-information-about-portable-air-conditioners.html HVAC technology developments today are giving facility executives options and solutions to their HVAC system requirements that were not available in the past. Equally important, they do not have to sacrifice performance or operating costs to implement these solutions. The growing dependency on air conditioning for building occupants and equipment cooling has given rise to an entire new generation of cooling equipment that is portable. While building air conditioning systems are very dependable, there are times when they simply aren’t available. Failure of central air conditioning or distribution equipment can shut down systems for extended periods of time.

• Boilers and HVAC Building Automation Systems
  Source: http://knol.google.com/k/julian-arhire/boilers-and-hvac-building-automation/2p0090difr5q/3# With the newest state-of-the-art sensors, direct digital controls and computer driven expert systems, buildings now can be completely automated and remotely controlled. This article will review what such systems and their operators can and cannot do, what new risks can be created for the boilers in such buildings, and how to reduce and control those risks. Benefits of automation Intelligent buildings today use a building automation system (BAS) and other systems to operate HVAC, boilers, chillers, lights, elevators, building access fire protection and other systems to achieve the twin goals of efficiency and comfort. A BAS is defined here as a system of sen

• DtiCorp.com is introducing 27 New Honeywell Thermostats
  DtiCorp.com (http://www.DtiCorp.com) is introducing 27 Brand New Honeywell Programmable Thermostats . Heating and cooling losses from a building become greater as the difference in temperature increases. A programmable thermostat allows reduction of these losses by allowing the temperature difference to be reduced at times when the reduced amount of heating or cooling would not be objectionable.

• Fresh Look At Ductless HVAC Systems
  While many types of HVAC systems are advancing, some advances are overlooked because they have occurred in some of the less glamorous types of HVAC systems: rooftop units, split ductless systems and portable AC units. The result of these gains is that facility executives have more options today when it comes to selecting systems and components to meet building needs. But having more options is good only if the most appropriate option is selected for a particular application. Simply rushing into using new HVAC technology without first understanding the appropriateness of that technology for a given application is a recipe for disaster. Inappropriate system selection can result in poor IAQ, poor system performance, high energy use, increased user complaints a

• The Benefits Of An HVAC Audit
  HVAC audits can be quite complex and involve dedicated personnel, or they can be less formal and folded into a preventive maintenance (PM) program. Focusing first on the biggest energy users — chillers, boilers and fan motors — maintenance and engineering managers can develop an audit program that locates substantial savings in energy costs, savings that often will pay for any additional maintenance burden created by conducting the audits.

• What Are The Rooftop HVAC Units?
  When rooftop units were first introduced some 40 years ago, they were considered by system designers and building owners to be a bare bones, low cost, simple solution to low-rise building HVAC needs. Low cost was the primary driving force for both manufacturers and users. But while they were popular with designers and owners, many maintenance managers considered them nightmares: difficult to service, prone to breakdowns, inadequately protected from the elements. Today, everything has changed. Gone is the concept of one size fits all. Buyers have more options, including practically all of the same features found in other types of building HVAC systems, from economizers for energy conservation and prewired interfaces for building automation systems to heat w
