Abstract

An air source gas-fired heat pump system intended to replace conventional condensing boilers is under development. The adsorption cycle uses ammonia refrigerant and activated carbon sorbent in four reactors with heat and mass recovery and has a nominal heat output of 7kW. Predicted annual average COP based on gross calorific value is 1.35 in a UK application with low temperature radiators. If this new technology were takenup across the UK it would result in an 8% reduction in UK carbon emissions. The system is described together with the simulation model, the test facilities and procedures. Initial test results are approximately 10% below predicted values but improved valves are expected to yield the target COP levels when system tests resume in April 2012.
