The present disclosure includes systems and methods for determining dimensions, shapes, and locations of rooms of a building using a mobile device for controlling heating, ventilation, and air conditioning (HVAC) provided to the rooms and building. A measuring device receives a shape of a room in the building and determines a dimension set of the room based on the shape of the room. The measuring device transmits the shape of the room and the dimension set to a mobile device that determines a layout of the building based on the shapes and the dimension sets corresponding to the rooms of the building. In this manner, the systems and methods provide the layout of the building more efficiently, resulting in an improved HVAC system installation and operation process.

Mobile device building layout determination systems and methods

A heating, ventilation, and/or air conditioning (HVAC) system includes a sensor configured to detect an operating parameter of the HVAC system, a processor, and a memory having instructions executable by the processor to cause the processor, during a normal operation mode of the HVAC system, to iteratively receive feedback from the sensor indicative of a value of the operating parameter, compare the value with reference data, and determine a refrigerant charge level of the HVAC system based on the value and the reference data.

A heating, ventilation, and/or air conditioning (HVAC) system includes a mobile air conditioning unit configured to separately dock with each docking station of a plurality of docking stations. The mobile air conditioning unit includes a refrigerant circuit configured to condition an airflow to produce a conditioned airflow and a transportation system configured to autonomously relocate the mobile air conditioning unit.

Embodiments of the present disclosure are directed to a condensate collection assembly that includes a condensate collection trough configured to couple to the heat exchanger, the condensate collection trough having a condensate receptacle and a channel, the condensate receptacle is configured to be positioned adjacent to a condensate flow path of the heat exchanger and receive a condensate from the condensate flow path, and the channel is configured to direct the condensate from the condensate receptacle to a condensate pan and a cover disposed over the channel, where the cover is configured to restrict a flow of air from entering the channel.

Cover for a condensate collection trough

The present disclosure relates to a flow generating device for a heating, ventilation, and/or air conditioning system. The flow generating device includes a housing having a channel defining a flow path of a fluid and a fan blade having a rotational axis extending through the channel, where the fan blade is configured to rotate to force the fluid along the flow path. A portion of the fan blade axially protrudes beyond the channel in a direction generally aligned with the flow path and a winglet extends from the portion of the fan blade.

A heating, ventilation, and air conditioning system may include a refrigerant loop to circulate refrigerant, a first valve, a second valve, a sensor to measure parameters of the refrigerant, a refrigerant tank fluidly coupled to the refrigerant loop via the valves, and control circuitry communicatively coupled to the sensor, the first valve, and the second valve. The control circuitry may determine environmental conditions and detect whether an undercharge or overcharge condition is present in the refrigerant loop based at least in part on the environmental conditions and the measured parameters. The control circuitry may also instruct the first valve to open when the undercharge condition is detected to facilitate flowing refrigerant from the refrigerant tank into the refrigerant loop and instruct the second valve to open when the overcharge condition is detected to facilitate flowing refrigerant from the refrigerant loop into the refrigerant tank.

HVAC refrigerant charging and relieving systems and methods

Systems and methods are disclosed that calibrate a defrost threshold used to determine when a heating, ventilating, and air conditioning (HVAC) system enters a defrost mode, and, more particularly, determine frost temperature differences used to determine the defrost threshold when the HVAC system is in a stable condition. A frost temperature difference is a difference between an outdoor ambient temperature and a refrigerant temperature. The HVAC system determines that it is in the stable condition by determining that a standard deviation of a current frost temperature difference from a previous frost temperature difference is below a standard deviation threshold. When the HVAC system is in the stable condition, the frost temperature differences are determined, and the defrost threshold is determined from the frost temperature differences.
