Design and operation of an innovative HVAC system for a net-positive energy solar decathlon house

Conference Paper


Abstract


  • This paper presents the design and operation of a novel Heating, Ventilation, and Air Conditioning

    (HVAC) system for a net-positive energy Solar Decathlon house that Team UOW constructed to

    compete within the Solar Decathlon Middle East (SDME) 2018 competition. The HVAC system

    primarily consists of an air-to-water heat pump, an Energy Recovery Ventilator, a

    dehumidification/humidification heat pump, a water-based Thermal Energy Storage unit using Phase

    Change Materials, and radiant panels. The HVAC system was developed to address the challenging

    climatic conditions in the remote desert environment of the competition site (and applicable to many

    parts of Australia) to provide energy-efficient indoor space cooling and acceptable indoor thermal

    comfort, together with the ability to shift HVAC peak energy demand. This new HVAC system was

    demonstrated during the competition period and successfully maintained indoor thermal comfort

    conditions, which resulted in Team UOW winning first and second places respectively in the thermal

    comfort and energy efficiency sub-contests, and second overall in the competition. In this paper, we

    introduce this innovative HVAC system, detail the unique design approach to mitigating the challenging

    climatic conditions, and discuss its operation during the competition.
