A system for drying compressed gas discharged from a gas compressor is disclosed herein. The dryer system includes a desiccant drying circuit and a refrigeration drying circuit configured to transport the compressed gas in parallel through the dryer system. The desiccant drying circuit and a refrigeration drying circuit are operable for removing moisture from the compressed gas and supplying a dried gas to an end user.

A method of managing thermal comfort, the method comprising: capturing a first facial thermal image of a first individual, using a thermal imaging camera; determining a comfort level of the first individual in response to the first facial thermal image; comparing the comfort level determined to a comfort range; determining that the comfort level is not within the comfort range; and operating a heating, ventilation, and air-conditioning (HVAC) system in response to the comfort level and the comfort range.

The present inventive concept includes a duct system and method for using same to map and locate ducts. A preferred embodiment of the duct system includes a duct, a plurality of electronic information modules and an oversheath at least partially covering the plurality of information modules and fixing the information modules to the duct. The plurality of information modules are configured to emit a positional signal to enable location of the information modules and associated duct(s) and/or mapping of the duct system.

A diffuser assembly for a heating, ventilation, and air conditioning (HVAC) system includes a housing having a wall and a passage formed in the wall. The diffuser assembly also includes a first adjustment panel moveably coupled to the wall and having a first flange and a second adjustment panel moveably coupled to the wall and having a second flange. The first flange and the second flange define at least a portion of an inlet port of the diffuser assembly that extends through the passage. The inlet port is configured to fluidly couple to a duct and direct an air flow from the duct into an interior volume of the housing. The first adjustment panel and the second adjustment panel are configured to translate along the wall to adjust a size of the inlet port.

A joint seal system and method may be configured to mitigate and/or eliminate leakage of pressure, flue gases, condensate, helium vent gas and/or any other fluid, gas, and/or vapor between abutting flanges of duct sections at a flange interface. A weld-free MRI machine quench vent discharge system using pre-fabricated chimney duct components may be configured by selecting a quench vent outlet and discharge location, mapping a route, and determining directional changes. Elbows and bellows sections are selected based on these changes, and the distance between the MRI machine and discharge location is calculated to determine support positions. The system is assembled using prefabricated chimney ducts, each comprising an inner shell with spinner bolt flanges and a leak-free joint with a PTFE gasket. The design includes an outer shell with an insulation gap for thermal protection.
