Hong Kong Researchers Unveil Solar-Powered Vehicle A/C Unit
Air conditioning units are crucial in cars — especially if you live in an area prone to humid and hot temperatures. However the problem with A/C units is that they consume a lot of fuel as they run. Fortunately, researchers from the Polytechnic University (PolyU) in Hong Kong recently announced that they have successfully developed and tested a solar-powered A/C system for vehicles.
Developed in collaboration with industry partners including Green Power Industrial Ltd, the A/C system consists of a photovoltaic module, a solar control system, an air-conditioning control unit, an electrical VFD (variable frequency-driven) compressor, and a cool air and temperature feedback system. The project was devised by Professor Eric Cheng of PolyU’s Department of Electrical Engineering, who designed it to be installed on trucks carrying beverages — we have already talked about the system being used in Coca-Cola’s fleet of vehicles, but this is the first time that the unit has been successfully tested.
