Abstract: This paper,taking a continuous heat recovery adsorption air-conditioning system/heat pump as study object,through dynamic analysis on system cycle characteristics,lists a series of dynamic equations about system main components such as adsorber,heat source,condenser,evaporator and so on.In the dynamic equations,variation of heat recovery process for adsorber is considered and a non-balance adsorption equation of adsorber is introduced.In addition,calculation methods of main performance parameters are also given.The work has laid a foundation for further analysis of cycle characteristics and dynamic performances.
