TESTS in the USA on a new hydrocarbon replacement for R22 in chillers is said to have shown a 9% improvement in energy efficiency.
Initial results of the testing on the pure hydrocarbon formulation developed by inventor Richard Maruya of A S Trust & Holdings were reported by Contracting Business. The results are said to confirm the compatibility of HCR188C2 as an energy efficient replacement for R22 charged systems.

The findings have led Jerico Energy, who carried out the testing, to suggest if hardware changes had been made it could have demonstrated even greater system performance improvements and reduced power usages (in kilowatts) close to 40 per cent.

The tests were run using two Carrier 50D104 Weathermaker IV chillers, installed in the Cal Expo facility in Sacramento California. For more information click here.
