  • Patent number: 5964370
    Abstract: A condensate pan is adapted for use in either a left or right horizontal fan coil installation, and includes left and right mirror image sides interconnected with a central section having on its lower surface a riser near one end, and each of the halves having a drainage opening on the other end, such that when the evaporator coil is placed in the condensate pan, the pan is tipped about the riser to lower one side and raise the other, depending on whether its a left or right horizontal installation, such that drainage occurs from the lower side drainage opening. The drainage opening is so located with respect to the floor of the pan that, when a drain pipe is threadably connected thereto, its lower inner surface is disposed vertically below the pan floor to thereby enhance its drainage characteristics.
    Type: Grant
    Filed: September 19, 1997
    Date of Patent: October 12, 1999
    Assignee: Carrier Corporation

  • Patent number: 5596879
    Abstract: A method for determining the optimum location for installing a muffler in a refrigerant line to reduce refrigerant line vibration caused by acoustical resonances. This method includes measuring the frequency of compressor discharge gas pulsations, ascertaining the speed of sound in the compressor discharge gas, calculating the wave length of the compressor discharge gas pulsation frequency, calculating a critical length, providing a refrigerant discharge line with a length equal to the calculated critical length to allow the formation of at least one standing wave in the discharge line, and installing a refrigerant line muffler in the refrigerant discharge line at a maximum of the standing wave.
