Sustainable heating system for extracting air from the outside environment to produce heat for indoor heating and hot water supply
An air-source heat pump uses the heat naturally present in outdoor air to provide heating, cooling, and hot water. By applying a reverse Carnot cycle powered by electricity, it transfers heat from a lower temperature environment to a higher one instead of generating it directly, making the process far more energy efficient. This type of hear pumps can work all year round, providing heat in winter and cooling in summer, and can be connected in parallel to meet different capacity needs and reduce startup costs.
Features
- Works without any combustion process, so it does not produce smoke, sulfur dioxide, or other harmful emissions.
- The refrigerant system is completely separated from water and electricity, eliminating the risk of electric leakage.
- An automatic defrost function ensures reliable operation even in low temperatures, making it suitable for environments above -25 °C.
- Their design avoids complex piping systems, and key components such as compressors and heat exchangers can have a lifespan of over 15 years.
Typical Applications
- Suitable for residential projects such as heating in northern regions converting from coal to electricity, integration with central air conditioning, and providing 24/7 hot water.
- Air-source heat pumps are suitable for hotels, resorts, and shopping centers where both heating and cooling are required.
- Widely used in agriculture and industry for processes like food drying, greenhouse climate control, and keeping livestock areas at a consistent temperature.
