The Renovation Methods Analysis for Current Buildings Air Conditioning Systems

Abstract

There are several problems in air current conditioning system, such as low energy efficiency, equipment aging, low operation efficiency, unnormal function, and poor thermal comfort. In order to better deal these issues, some renovation methods (including installation of ground source heat pump system, changing cold and heat source, reasonable using of displacement ventilation & natural ventilation, and strengthening the automatic control system) for current building air conditioning were suggested. The results show that the operating and energy efficiency characteristic current air conditioning system could be improved to a great extent through these methods employment.
