  • Patent number: 10514174
    Abstract: A split air conditioner has a cabinet with a fan and evaporator for mounting within a structure. The cabinet includes one or more movable dampers or movable filters positioned in the flow path between the air inlet and the outlet for selectively filtering contaminants from the air to provide a greater or lesser degree of filtration of the air. The movable filters include sliding and/or pivot mounting structure which may accommodate stacking multiple filters with different filtering characteristics. The system may operate in a filtering only mode with no cooling, a cooling only mode with no filtering, or a combination of cooling and selective filtering.

  • Patent number: 10132548
    Abstract: A refrigerator includes a secondary cooling path for circulating liquid coolant through the refrigerator wherein the liquid coolant is cooled by the freezer compartment and wherein the liquid coolant cools the ice maker and the ice bin as the liquid coolant circulates through the secondary cooling path. A pump is positioned along the secondary cooling path for pumping the liquid coolant through the secondary cooling path. A tube having a first end proximate the pump and an opposite end exposed to atmosphere may control suction pressure associated with the pump. The refrigerator reduces frost build up through configuration of the secondary cooling path or performing ice harvesting operations which melt frost. The secondary cooling path may be used to provide for circulating hot liquid. The secondary cooling path may be used to provide for circulating liquid coolant during a power outage.

  • Patent number: 9803898
    Abstract: An outdoor unit (ODU) for an air conditioning system includes a baffle or other airflow direction control such that the cooling air from a condenser is at least partially directed over the compressor to provide air movement around the compressor to assist in thermal transfer of heat from the compressor. In one system, curvilinear frustoconical baffles are positioned in a conventional barrel-type outdoor unit to direct airflow toward the compressor before being discharged from the unit. When any of the ODUs is part of a heat pump system for providing heating and cooling, a retractable or movable air diverting system is employed when in the heating mode to prevent airflow through the condenser from reaching the compressor.

  • Patent number: 9719711
    Abstract: An ice making assembly and method utilizes a housing having an upper fluid chamber, a plurality of distinct, substantially vertical fluid channels, and at least one drain aperture in fluid communication with a fluid reservoir. Ice forming members extend from an ice forming evaporator into respective fluid channels. During an ice making event, fluid continuously supplied to the upper fluid chamber flows into each of the fluid channels and out through at least one drain aperture into a fluid reservoir below. The ice forming members are cooled such that fluid flowing across the fluid channels freezes on the ice forming members over time, forming clear ice pieces. The ice pieces are subsequently released from the ice forming members and transferred for storage and/or dispensing.

  • Patent number: 9714785
    Abstract: An appliance includes a cabinet; a first compartment; and a second compartment. The first compartment and the second compartment are separated by a horizontal mullion. The cabinet also typically includes a coolant system that has: a single compressor for regulating a temperature of the first compartment and a temperature of the second compartment operably connected to at least one evaporator; a shared coolant fluid connection system; and a coolant fluid spaced within the shared coolant fluid connection system used to regulate both the temperature of the first compartment and the second compartment. The compressor can provide the shared coolant at least two different pressures to at least one evaporator using the shared coolant fluid connection circuit. The ratio of the substantially steady state heat gain for the first compartment to the substantially steady state total heat gain for the overall cabinet is about 0.65:1 or greater.
