As of 2023, the latest developments and technological advancements in the field of Air Source Heat Pumps (ASHPs) abroad mainly focus on the following aspects:
- Market growth and policy support
-Europe: The air source heat pump market is growing rapidly, especially in Germany, France, Nordic countries, etc. The EU’s “Green Deal” and “Repower EU” plans have promoted the popularization of heat pumps, with the goal of installing 10 million heat pumps by 2030.
-The United States provides tax incentives and subsidies for heat pumps through the Inflation Reduction Act (IRA), encouraging households and businesses to adopt clean heating technologies.
-Japan: Air source heat pump technology is mature and widely used in households and commercial buildings. The government further promotes it through subsidies and energy-saving policies.
- Technological innovation
-Low temperature performance improvement: The new generation of air source heat pumps can still operate efficiently in low temperature environments (such as -20℃), making them suitable for cold regions in Northern Europe and North America.
-Variable frequency technology: Variable frequency compressors can adjust their output according to demand, improving energy efficiency and comfort.
-Intelligent control: Through AI and IoT technology, heat pumps can learn user habits and automatically optimize operation, such as integrating with smart home systems.
- Environmentally friendly refrigerants
-To reduce greenhouse gas emissions, many manufacturers have started using refrigerants with low global warming potential (GWP), such as R32 and R290 (propane).
- Combination of heat pump and photovoltaic
-In Europe and Australia, more and more households are combining air source heat pumps with solar photovoltaic systems, using solar power to operate the heat pumps and further reduce their carbon footprint.
- Regional application cases
-Nordic countries: Sweden and Norway widely use air source heat pumps due to their high energy efficiency and environmental characteristics.
-UK: The government plans to install 600000 heat pumps annually by 2028 and gradually phase out gas boilers.
-United States: Cold regions (such as New York State) encourage households to install air source heat pumps through subsidies.
- Challenges and Solutions
-High initial cost: Although the long-term operating cost of heat pumps is low, the initial installation cost is relatively high. Many countries alleviate this problem through subsidies and loan programs.
-Increased electricity demand: With the popularization of heat pumps, electricity demand may rise, and it is necessary to strengthen power grid construction and renewable energy generation.
- Future Trends
-Miniaturization and modularization: Heat pump products suitable for small households and apartments are currently under development.
-Heat pump water heater: Air source heat pump water heaters are gradually becoming popular in the European and American markets, with much higher energy efficiency than traditional electric water heaters.
