Air velocity is a key parameter in evaluating airflow system performance. As part of basic testing, adjusting and balancing of HVAC air distribution systems, most HVAC technicians now use an anemometer to measure air velocity at grilles-registers-diffusers, within a duct, or in open spaces.

October 2014 | HVACIf chilled water flow is interrupted for even a few minutes the IT server room might overheat and critical computer services could go down. Another vital area is a hospital operating room. In a plant, essential machinery uses chilled water for process cooling. While many plants have excess capacity, much of this capacity is not available at high ambient temperature and high humidity conditions.

March 2014 | HVAC- One of the possible problems in facilities today is the presence and effects of mold on the indoor environment. Molds are normally present in nature. They reproduce by means of tiny spores that float through the air and are invisible to the naked eye. They can grow on wood, paper, carpet, foods, and insulation - but none of the many types of mold will grow without water or moisture. When excessive moisture accumulates in buildings or on building materials, mold growth will often occur, particularly if the moisture problem remains unaddressed.April 2012 | HVAC

Understanding the relationship between dry bulb temperature, wet bulb temperature, relative humidity, and dew point temperature is essential in all facets of air conditioning. These psychrometric processes play an especially important role in building and materials integrity, occupant health and comfort, and overall indoor air quality.April 2012 | HVAC- The 975 gathers ten fundamental IAQ parameters: Temperature, Humidity, Dew Point Temperature, Web Bulb Temperature, Carbon Dioxide, Carbon Monoxide, Air Velocity, Air Volume, and Percentage of Outdoor Air (calculated from temperature or CO2). This application note reviews those parameters and the associated functions on the 975. For more detailed information, see other app notes from the Fluke HVAC/IAQ library.April 2012 | HVAC

- HVACR mechanics rarely rely on a single test to pass or fail a function or process. As they walk up to a condensing unit, they listen, they wave their hand over the condenser discharge air, and then they grab the suction line, the liquid line, and the discharge line (and wish they hadn't done that). All of this before they even open their tool box.January 2019 | HVAC
- Five years ago, with the move to highefficiency equipment, Fluke began receiving trouble calls from service techs. The calls came post-installation, and they weren't about the new equipment—they were about other parts of the system that were now operating erratically, if at all.March 2012 | HVAC
Examine six areas when deciding on the best insulation resistance tester for the application. Consider the equipment to be tested, test voltage requirements, the testing environment, other possible uses, the experience level of those using the tester, and measurement safety features of the insulation resistance tester.February 2013 | HVAC
Most of the hours when comfort cooling systems operate are well below outdoor design conditions. The equipment may have been selected to maintain 75°F and 50% RH indoors when it is 95°F outdoors, but what happens at lower outdoor temperatures? There's less run time to satisfy the thermostat, but not enough run time to maintain desirable or comfortable humidity levels. Some modern equipment and components are designed to overcome this effect.April 2012 | HVAC
