Feasibility analysis of energy efficiency reformation of an existing office building lobby with floor panel cooling and heating system

Taking the lobby of an existing office building in Beijing as study object, considering the weather conditions and the air conditioning load characteristics, performs the energy efficiency reformation of air conditioning system based on the theory and principle of floor panel cooling and heating technology by replacing the original floor panel heating system to a floor panel cooling and heating system. The running results in summer of 2009 show that the reformation has satisfied the demands of building thermal comfort and function with significant energy saving effects.
