Abstract: An air handling unit (AHU) for a heating, ventilation, air conditioning, and refrigeration (HVACR) system includes a housing and a combustion heater disposed within the housing. The housing includes a combustion section with a first channel and a second channel. The combustion heater includes heat exchanger tubes and a tube support that supports heat exchanger tubes within the combustion section. The tube support slidably disposed in the first channel and the second channel. The combustion heater configured to be slidably removable from the AHU. An AHU for an HVACR system includes a housing with a fan section and a fan assembly disposed within the housing. The fan assembly including a pair of grooves slidably disposed on a pair of rails of the housing. The fan assembly configured to be both slidably removable from the AHU and liftably removable from the AHU.

Abstract: This disclosure relates to generating a virtual space based on a physical layout of objects. The virtual space may be generated based on the physical layout of objects by one or more of identifying physical objects in a real-world space, determining a physical arrangement of the identified physical objects, determining virtual space content for the identified physical objects and the physical arrangement of the identified physical objects, executing an instance of the virtual space, and/or other operations. The virtual space may include the virtual space content determined based on individual virtual space content associated with the identified physical objects and the physical arrangement of the identified physical objects. The instance of the virtual space may be used to facilitate presentation of one or more views of the virtual space to a user and enable the user to interact with the virtual space.

Abstract: This disclosure relates to system and methods for providing augmented reality experience based on a relative position of objects. Augmented reality experience based on a relative position of object may be provided by detecting a first object and a second object. Positions and orientations of the first object and the second object may be determined. A first visual effect may be determined for the first object and a second visual effect may be determined for the second object. Overlay positions and orientations for the first visual effect and the second visual effect may be determined. An overlay image including the first visual effect and the second visual effect may be determined, and the overlay image may be displayed. An interaction between the first visual effect and the second visual effect may be determined based on the relative position of the first object and the second object.
