Résumé

A dual lift water ammonia low temperature driven absorption cycle has been developed in which the refrigerant flow self adapts to the evaporator and absorber loads. A 3.4 kW air cooled chiller unit has been fully simulated and a prototype built and tested. The unit was run with hot water at inlet temperatures from 70°C to 95°C and with air temperature ranging from 25°C to 40°C . On the entire range of testing conditions the chiller delivers cooling capacity and runs smooth in transient and stable in steady state. In the current prototype setup ongoing test, at 35°C outdoor ambient temperature, 7°C outlet chilled water, 92°C driving hot water the chiller prototype has a cooling capacity of 3.4 kW with a COP of 0.29 and 360 W power consumption for the fan and the solution pump. At 32°C outdoor ambient temperature, 7°C outlet chilled water, 79°C driving hot water the prototype has a cooling capacity of 2.5 kW with a COP of 0.28 and 285 W power consumption for the fan and the solution pump.
