摘要： A method may include selecting a first set of values for a first set of parameters of one or more hardware components of an ice-making machine; identifying a water temperature at a water inlet of the ice-making machine; identifying an ambient air temperature surrounding the ice-making machine; calculating a second set of parameters of the ice-making machine based on at least a portion of the first set of values, the water temperature and the ambient temperature, the second set of parameters corresponding to operation of the ice-making machine in a freeze mode in which liquid water is cooled by an evaporator; and calculating a third set of parameters based on at least a portion of the first set of values, the water temperature and the ambient temperature, the third set of parameters corresponding to operation of the ice-making machine in a harvest mode.

摘要： Systems and methods for purging lubricant from a first compressor to a second compressor are provided. A control module receives a lubricant purge command, shuts the second compressor to an OFF-mode while the first compressor remains in the ON-mode, restricts working fluid from an outlet of the second compressor from flowing into the first compressor and allows compressed working fluid discharged from an outlet of the first compressor to flow into the inlet of the second compressor such that lubricant in the second compressor flows into the first compressor.
