Multi-heat source application to a winery project in alpine and remote area of Yunnan

Presents the HVAC design for a winery project located in an alpine and remote area of Yunnan where no adequate sustainable supply of gas, coal, oil and other fuels, but abundant solar energy. After investigation and analysis, adopts solar heating system, air-source heat pump unit and electrical auxiliary heating equipment as multi-heat sources to meet the needs of heat supply for production and living in winter, and natural ventilation or mechanical ventilation to satisfy the requirements of indoor comfort and hygiene in other seasons. The project operation results show that the design requirements have been achieved.
