Sensors in the solar cooling installation.
Finally, inTable

, the large number of sensors installed in the solar cooling instal-
lation can be observed. A large part of these sensors are located in the plant, since
most parts of the machines associated with the solar cooling installation (boiler,
storage tanks, absorption machine, pumps, etc.) are situated there. More specifi-
cally, most of these sensors can be observed in Fig.
