Abstract:

The Thermo-Chemical Accumulator, a three-phase chemical heat pump with integral thermal storage, has been tested and modelled in the TRNSYS simulation environment. Base case system models for solar cooling applications were created for the Madrid and Stockholm climates and a number of parametric studies were carried out. The results show that the temperature lift, partially dependent on state of charge, is a limiting factor. For a purely sensible cooling load, wet cooling is required for the Madrid climate, whereas in Stockholm a dry cooler can be used for the simulated office and hotel. Dehumidification is not possible. It was shown that the machine itself has sufficient thermal storage for the office load but that it limited the solar fraction for the more uniform hotel load.
