ABSTRACT 

This paper presents the design and manufacturing of a novel carbon-ammonia adsorption generator for application to an air source domestic gas fired heat pump and also shows preliminary test results of the complete heat pump system. This laminated generator has the characteristic of delivering high heating power at a high efficiency but having an inexpensive manufacturing cost. 

The machine which is about to be tested has a predicted power output of between 5 and 10 kW at a COP of 1.40 to 1.35 for low temperature radiators for domestic applications.
