  • Patent number: 10837679
    Abstract: A condenser system that includes a first compressor and a second compressor. An upper coil and a de-superheater coil are fluidly coupled to the first compressor. The upper coil, the de-superheater coil, and the first compressor define a first compressor circuit. A lower coil is fluidly coupled to the second compressor. The lower coil and the second compressor define a second compressor circuit. The upper coil and the de-superheater coil together utilize an entire heat-transfer surface area.
    Type: Grant

  • Patent number: 10563883
    Abstract: A heating, ventilation, and air conditioning (HVAC) system is configured to receive a signal from a thermostat. The signal instructs the HVAC system to operate a component in a partial load mode. The HVAC system is further configured to determine that the component has exceeded its operating envelope. In response to determining that the component has exceeded its operating envelope, the HVAC system is configured to operate the component according to an override configuration. The override configuration overrides the signal to operate the component in the partial load mode.

  • Patent number: 10161650
    Abstract: Retrofit assemblies and an HVAC unit including a retrofit assembly are disclosed herein. In one embodiment, the retrofit assembly includes: (1) a base plate, that is mountable to a face of a motor speed driver (MSD), having an attachment area, (2) a standoff bracket that is mountable to the attachment area of the base plate and having a configuration that secures the MSD in a position relative to an interior wall of the HVAC system and provides clearance between the interior wall of the HVAC system and the MSD such that wires can be routed between the MSD and the interior wall and (3) a control interface, electrically connectable between the MSD and a thermostat of the HVAC system, configured to differentiate thermostat calls from the thermostat and translate the thermostat calls to coordinate blower speeds for the blower motor via the MSD.
