For economic evaluation, the cold room at capacity 3,000 kg by
using the 10 kW absorption system is also carried out with 10 sets of
cooling per month, 24 hours per freezing set. At the time of assessment
with the construction cost about 20,000 USD and the payback period
is 22 months.
Table 8 shows 8 moderate potential hot springs at temperature
between 70-80°C at the most found in the northern area of Thailand.
Moreover, Table 8 also shows the total cooling capacity at around 304
kW of absorption chiller from 8 hot spring resources.
