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. The temperature control system, integral to the unit, includes indoor and outdoor heat exchangers that move with the mobile section, allowing for effective heat transfer. Additionally, the unit features an air return system with a blower unit and extendable strut to facilitate airflow through the indoor heat exchanger, enhancing overall performance.

Furthermore, the environmental control unit includes a carriage mechanism for smooth movement between stowed and deployed positions, creating plenums for air circulation through the heat exchangers. The air return and air supply components are designed to extend and retract with the carriage, optimizing airflow through the system. With additional features like a fan assembly to pull air through the outdoor heat exchanger, the unit aims to provide efficient temperature control while maximizing space utilization and mobility.
