October 10, 2003—The Stealth Hot Heat Pump series from York International’s Unitary Products Group couples the industry’s first Twin-Single (TS) compressor with the microprocessor-based York Comfort Enhancer Control in units ranging in capacity from two to five tons.
TS technology employs two pistons that operate together under high load situations for maximum heating power. When less heating is required, the compressor moves to single piston operation, reducing operating costs without sacrificing comfort. This translates to fewer start-and-stop cycles, which reduces wear and tear and extends the life of the unit.
Fewer start-stop cycles help maintain constant temperatures and eliminate hot spots, says York. The longer operating cycles increase air circulation and help improve humidity control. The heat pump has a discharge heat temperature of 110 F, rivaling a furnace, according to the company. When the season changes, it automatically converts to a highly efficient central air conditioning system. With an HSPF rating of 9.3, the Stealth series can significantly reduce operating costs. Noise levels are kept low since the TS technology keeps noisy on-off cycles to a minimum, plus the unit contains a wide range of other sound-dampening devices.
