Experimental study on the dynamic characteristics of adsorption heat pumps driven by intermittent heat source at heating mode

The influence of intermittent heat source on adsorption heat pumps is an unavoidable problem when the system is put into practice. This work studies an adsorption heat pump system driven by intermittent waste heat supplied at 110 °C and dynamic characteristics are obtained under 8 working conditions with water temperature at about 41 °C. The cycle time is 40 min including 120 s heat recovery time. This paper also gives the parameter variation regulations of the system driven by intermittent heat source. The experimental results show a decrease of specific heating power (SHP) and coefficient of performance (COP) is up to 26% and 8.7%, respectively.
