  • Publication number: 20240133575
    Abstract: A method is provided for controlling an HVAC system. The method includes receiving zone priority levels and zone temperature setpoints, where at least one of the zones haves a higher priority level than others of the zones, receiving an indication of zone ambient temperature values, determining requested zone capacity values to maintain the zone ambient temperature values within a threshold deviation of respective ones of the zone temperature setpoints, determining target zone capacity values from the requested zone capacity values and zone size values, and from the zone priority levels where the target zone capacity values may be responsive to a total of the requested zone capacity values that is less than a minimum capacity or greater than a maximum capacity of the HVAC system, and causing the HVAC system to provide the conditioned air to the zones according to respective ones of the target zone capacity values.

  • Patent number: 11774151
    Abstract: Example embodiments of the present disclosure relate to a heat pump assembly including a system or method for detecting a fault in the heat pump. Some embodiments include a method for detecting a switch over valve fault where the heat pump includes a refrigerant cycle, a compressor, a metering device, a first heat exchanger, an second heat exchanger, a temperature sensor, and a switch over valve, and where the method includes operating the HVAC system in one either a heating mode or a cooling mode, monitoring a refrigerant temperature associated with the refrigerant cycle using the temperature sensor, monitoring an outdoor ambient air temperature, determining a temperature difference between the refrigerant temperature and the outdoor ambient temperature, determining whether the temperature difference is greater than a predetermined temperature difference threshold, and declaring a switch over valve fault when the temperature difference is greater than the predetermined temperature difference threshold.

  • Patent number: 10928076
    Abstract: Described herein are embodiments of a furnace inlet water collector for an HVAC system. The inlet water collector may include a base having an air intake aperture; an inner wall having a first top end and a first bottom end, the first bottom end provided proximate to the base; an outer wall having a second top end and a second bottom end, the second bottom end provided proximate to the base, the inner wall having a diameter smaller than a diameter of the outer wall; one or more pipe stops provided proximate to the base and between the inner wall and outer wall, a height of the one or more pipe stops extending less than a height of the outer wall; and a drain coupled to the outer wall and in fluid communication with a channel displaced between the inner wall and the outer wall.
