Sanyo’s ‘LPG powered’ GHP air conditioning system

How does it work? This new approach to air conditioning uses commercial grade liquid propane gas (LPG) as used for heating, as a fuel to power a Sanyo gas-driven heat pump VRF air conditioning system.

At the heart of the system is a modified two-litre Nissan engine, operating at between 800-2100rpm. It is equipped with conventional engine components, such as spark plugs, oil and air filter, as on a standard car.

The system only requires connection to a single-phase power supply to power start-up, control circuit and inverter-driven fans. The technology is highly efficient, ranging from between 1.4 (140%) to 1.6 (160%) when used as a heating or cooling system respectively. These figures are based on 100% load capacity but, as with all VRF type products, efficiency improves significantly at part-load conditions.

Spin off benefits – Additionally the system provides 22kW of ‘free’ hot water @ 65ºC



plus electricity generation which can be used in the building for lighting and domestic services.



If both ‘free’ hot water and electricity are utilized it is possible to deliver efficiencies up to 220%.
