5.5.2 Consumption Aggregating in Case of Thermally Compression
Chiller
The structure of a mCCHP system with a thermally compression chiller is presented
in Fig.
24
. The heat load of the mCCHP system must cover the heat consumption of
the residence, as well as the heat consumption for cooling. The heat consumption
