The global population growth together with the economic development results in the rapid acceleration in world energy consumption. EIA predicts the increase in global energy demand will increase by 47% in next 30 years. The severe energy situation has attracted much attention on power generation from renewable energy resources. Air-conditioning (cooling) is the fastest growing end-use in buildings. While highly efficient air conditioning (AC) units are available on the market, most consumers purchase models that are two to three times less efficient. Implementing energy efficiency standards could improve AC energy performance by around 50% by 2030 and help put cooling on track with the Net Zero Emissions by 2050 Scenario. This presentation demonstrates the waste heat recovery potential from air-conditioning systems and methods for waste heat recovery using some environmentally friendly refrigerants from Hong Kong’s perspective.
