A recently granted patent (Publication Number: US11920804B2) discloses an innovative environmental control unit designed to efficiently heat or cool air. The unit comprises a base section and a mobile section that can move between a collapsed-storage position within the base section and an expanded-use position extending from it. A temperature control system is integrated into the unit, with an indoor heat exchanger coupled to the mobile section and an outdoor heat exchanger connected to the base section. The air return system includes a blower unit, an extendable strut, and a flexible shroud, all working together to facilitate air flow through the indoor heat exchanger for effective heat transfer.

Furthermore, the environmental control unit features a unique design where the mobile section includes a carriage for movement, an air return system, and an air supply system. The movement of the carriage and the air return system creates different plenums within the unit, allowing air flow through the outdoor and indoor heat exchangers. The air supply system includes a flexible shroud, a hanger, and a flap that can be adjusted to control air flow. Additionally, a fan assembly is incorporated into the base section to pull air through the outdoor heat exchanger, enhancing the overall efficiency of the unit in regulating indoor temperatures. The patent highlights the advanced mechanisms and configurations employed in this environmental control unit to provide effective and versatile temperature control solutions.
