Novel compact sorption generators for heat pump applications
Metcalf, S.J., Tamainot-Telto, Zacharie and Critoph, Robert E. (2008) Novel compact sorption generators for heat pump applications. In: 9th International Energy Agency Heat Pump Conference 2008, Zurich, Switzerland, May 20-22, 2008Full text not available from this repository.
A new type of liquid-solid heat exchanger-reactor (carbon-ammonia) has been developed for use in adsorption cycles. It has the requirement to be of low thermal mass and also to have good heat transfer. The design solution chosen is a novel plate heat exchanger. It uses nickel brazed shims and spacers to create adsorbent layers only 4 mm thick between pairs of liquid flow channels of very low thermal mass. Prototype sorption generators have been manufactured and are being evaluated. The design is being used in a gas-fired heat pump, intended to replace a combi-boiler in the UK or similar climate. The heat pump uses two generators operating out of phase in a regenerative cycle. The system is described. Initial heat and mass transfer experiments on the generator are presented together with predictions of performance in the chosen application.
