  • Patent number: 5720178
    Abstract: In a vapor compression refrigeration system an improvement for isolating the compressor from work on a substantial component of refrigerant flashing to vapor upstream of the evaporator, wherein refrigerant liquid from the condenser is collected in a holding vessel from which it is intermittently emptied into an expansion device thereby generating flash vapor in the holding vessel which is prevented from passing through the expansion device and evaporator for return to the compressor.
    Type: Grant
    Filed: July 15, 1996
    Date of Patent: February 24, 1998
    Assignee: Calmac Manufacturing Corporation
    Inventors: Brian M. Silvetti, Mark M. MacCracken
  • Patent number: 5598720
    Abstract: In coolness storage apparatus wherein brine in heat exchange tubes freezes and melts water and air is bubbled up through the water during the melting cycle to enhance heat exchange efficiency by gently circulating the water, vertical heat transfer strips in thermal conducting contact with the tubes for accelerating melting along each strip early in the discharge cycle to open channels through which the air bubbles stream to the top zone of the tank.
    Type: Grant
    Filed: August 2, 1995
    Date of Patent: February 4, 1997
    Assignee: Calmac Manufacturing Corporation
    Inventors: Mark M. MacCracken, Brian M. Silvetti, Jose R. Bonet
  • Patent number: 5005368
    Abstract: A coolness storage air conditioner appliance in which water is frozen in chambers during protracted charging cycles by refrigeration apparatus of sufficiently low capacity to permit heat discharge into an interior air space and is melted during brief cooling cycles by air circulated through passageways in heat-transfer relation with the ice, the discharged circulated air thereby cooling the interior air space.
    Type: Grant

  • Patent number: 4608836
    Abstract: A multi-mode off-peak storage heat pump system for a building which includes a unidirectional flow refrigerant circuit and a brine circuit in selective heat exchange relation with one another, each being connected to a dual coil in ducts wherein air can be circulated within and between the inside and outside of the building, and an ice bank in the brine circuit for coolness and low-level heat storage, the system providing heating and cooling with no refrigerant reversing valves or coil defrost means and with optimum off-peak power utilization.
