Theodoma Technology During an air conditioning/refrigeration cycle or boiler usage, waste heat is normally thrown away into the atmosphere. The Theodoma system takes that low grade heat and converts it to usable electricity. Its low temperature power generator recovers in the region of 10% of the power input to air conditioning systems, refrigeration systems and boilers, thus creating in the region of 30% cost savings in the running of this type of equipment. It can also convert in the region of 10% of the waste heat from boilers to useble electricity. Here is an example of a dual low/high temperature energy recovery system -
