Abstract: A self-contained, integrated, modular HVAC system includes a plurality of adaptive or interchangeable components or swappable modules interconnected to enable the modulation of total airflow and total cooling capacity (sensible plus latent) to meet variable loads and adjust a sensible heat ratio (SHR) to meet a variable latent ratio of a conditioned space. The components comprise one or more air inlet, damper, inlet damper, air filtration module, air purification module, air freshener module, dehumidifying module, cooling module, air bypass module, blower module, air outlet, I/O panel, and a control cabinet. The components have sensors and actuators that allows a programmable control system to coordinate diagnostics and operations of internal and external components of a refrigeration/heating cycle using various feedback control logics.

Abstract: A welding assembly includes an adapter, a diffuser, and a nozzle. The adapter includes an inner portion, a discharge portion, and an engagement portion. The discharge portion defines an outer periphery and at least one aperture. The diffuser defines a contact end, a diffusion end and an outer periphery. The contact end is engaged with the discharge portion of the adapter. The nozzle includes a discharge end, an engagement, end and an inner surface. The engagement end defines a groove and engages with the engagement portion of the adapter. The groove and the outer periphery of the diffuser defines at least one discharge passage within the engagement end of the nozzle. The inner portion of the adapter is in fluid communication with the inner surface of the nozzle through the aperture the discharge passage. Shielding gas is directed toward tip portion of the contact tip through the discharge passages.
