區域供暖
District heating, also known as heat networks or campus heating, is a system that transports heat to residential and commercial buildings through insulated pipes. This heat can come from a variety of traditional and green sources like combined heat and power, energy for waste, geothermal, solar thermal, and waste heat recovery. Alfa Laval’s energy efficient plate heat exchangers can support all district heating processes, reducing carbon emissions and demand for primary energy at the same time.

Trends in district heating industry
Today, the heating sector is influenced by multiple trends. These trends are mainly driven by increased expectations and targets in decarbonization, energy supply security and energy affordability, customer usability, and energy-efficient performance.
Some of the focused trends in the district heating sector are:
- Low grid temperature. Newly built grids for low temperature or existing grids where operating temperatures are being lowered
- Energy sources: changing fossil fuels to renewables and recycled energy
- Centralized production is complemented by decentralized/local production
- New flexible solutions in terms of supply and network size
- Trend in the sector to work more long-term with investments, digitalization and asset management
- Extended involvement and interaction with the end user to work with energy efficiency and reuse heat. Some customers can be viewed as “Prosumers” – both consumers and producers – not only using but also delivering energy to the grid at times.

Alfa Laval Solutions in District heating
In the district heating industry Alfa Laval is supplying heat transfer solutions for energy generation and for substations connecting buildings to the distribution network. Low return temperature increases the efficiency of the total district heating system and should always be the main target for any grid operator.
Production
Generating energy from any source
Alfa Laval heat exchangers can be used to extract heat from the source, whether you are working with renewable energy, data center heat recovery, or even green hydrogen.
Turning excess heat into an affordable heat source
Heat pumps can be used in all kinds of settings, reusing energy for both heating and cooling purposes. Alfa Laval heat exchangers are used in heat pumps of all sizes, supporting energy efficient, reliable heat transfer at even the lowest temperatures.
Distribution
Grids
In some locations heat exchangers are used as pressure breakers. This can be in extensive networks where height and altitude restrictions occur, or, most commonly, in substations between two networks and from distribution networks to buildings.
Demand
End User
Heat exchangers are needed here for two main reasons. Firstly, they are used to isolate and protect the individual buildings from the higher pressures and temperatures available at distribution level. Secondly, they limit the damage that can be caused by a leak in the heating system.
Products
Five generations of district heating
Alfa Laval has been working with the district energy sector for over 70 years, developing new heat exchangers that fit the industry’s specific requirements. Since the first generation of district heating, heat exchangers have been at the heart of their applications. Today, as we look towards generation five, the need for reliable, efficient heat transfer is stronger than ever. Alongside consultants, system builders, energy companies, and our partners, we are driving the transition to a new energy landscape. Contact your local Alfa Laval office to find out how.
