Cold Water Production by Means of Heat Energy from Husk

The system of cold water production by means of heat
energy from rice husk is a joint project of the Royal Chitralada Projects, the Electricity Generating Authority
of Thailand and the Fund for the Promotion of Energy Conservation. It aims at maximising the uses of rice
husk, a byproduct of the Suan Chitralada Experimental Rice Mill, for energy conservation.

To produce cold water, rice husk is burned in the double cyclonic furnace designed to be environmentally friendly. In the furnace, it is a complete combustion. The hot air produced is clean with no smoke. Then, the heat
serves to produce cold water, approximately 7 degrees Celcius, through an absorption chiller.

The cold generated from that water is used for operating the air-conditioner
of the Sala Maha Mongkol, a reception hall for visitors, and for the study of
temperate zone mushroom culture.
