Integration of an adsorption chiller in an open cycle desiccant assisted air conditioning system.

Number: pap. n. 90

Author(s) : SPEERFORCK A., SCHMITZ G.

Summary

In a pilot installation at Hamburg University of Technology the coupled operation of an open cycle desiccant assisted air conditioning system with an adsorption chiller in combination with cooling ceilings to remove sensible loads is investigated. The paper presents experimental results of the year 2013 with a special focus on the performance of the adsorption chiller. Furthermore, the system is compared to a similar system relying on a vapor compression chiller. The average thermal COP of the adsorption chiller during the investigated period is satisfying (COP th = 0.54), while the average electrical COP does not meet the expectations (COPel = 6.2). The fan control of the dry cooler can be identified as a main cause for the non-satisfying electrical performance. However, depending on the heat supply, up to 29 % of the primary energy demanded by a reference hybrid air conditioning system can be saved by the investigated pilot installation.
