    Insulation resistance and electrical testing for HVAC compressor motors

    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.

    My chiller plant is down, do you know how incredibly critical it is?

    If 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.

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.
  • Diagnosing mold problems

    Diagnosing mold problems

    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.
  • Battling high humidity levels in comfort cooling systems

    Battling high humidity levels in comfort cooling systems

    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.
