Abstract: An HVAC system for enhanced source-to-load matching without sacrificing airflow delivery in low load structures. Embodiments of the present disclosure provide for an HVAC system for enhanced source-to-load matching in a low load environment, i.e. dwellings with a BTU/hour capacity of less than 18,000. Prior art HVAC equipment is oversized for dwellings with a BTU/hour capacity of less than 18,000 that are insulated to minimum code requirements. Embodiments of the present disclosure provide for an HVAC system that separates the delivery of airflow (CFM) output from that of the BTU capacity output, thereby enabling a distributed delivery system for optimal source-to-load matching without sacrificing airflow delivery in low load environments. The source-to-load matching enabled by the present disclosure ensures optimal indoor air quality, enhanced comfort for occupants of the dwelling, and approximately a 60% reduction in heating and cooling costs when compared to prior art HVAC systems.

Abstract: Described herein is an improved HVAC system and method of configuring an HVAC system for cost-effective installation and energy efficient operation for multiple unit residential buildings. In one example embodiment, a mechanical room is sized to simultaneously house most of the HVAC equipment but to also advantageously operate as the HVAC system's air mixing chamber for a wall-mounted temperature and humidity conditioning unit and a blower assembly, based on maximum heating and cooling loads and the minimally required air flow requirement for a defined living space. This advantage allows for elimination of one or more mechanical plenums for air mixing space as well as flexibility in locating HVAC components in the space provided.
