Abstract
An ice cube-making machine that is characterized by noiseless operation at the location where ice cubes are dispensed and be lightweight packages for ease of installation. The ice cube-making machine has an evaporator package, a separate compressor package and a separate condenser package. Each of these packages has a weight that can generally by handled by one or two installers for ease of installation. The noisy compressor and condenser packages can be located remotely of the evaporator package. The maximum height distance between the evaporator package and the condenser package is greatly enhanced by the three package system. A pressure regulator operates during a harvest cycle to limit flow of refrigerant leaving the evaporator, thereby increasing pressure and temperature of the refrigerant in the evaporator and assisting in defrost thereof.
