Use of district heating equals higher individual comfort and energy efficiency

The basic principles behind district energy are remarkably simple. At one end of the network is an energy source (often a multi-fuel CHP plant). Heat is then distributed via a network of insulated pipes to residential, commercial and industrial buildings across the city.

At the end-user level, individual buildings are connected to the district heating network. In the building a substation with heat exchangers and various control components efficiently transfer hot water for room heating and domestic hot water (DHW) purposes into a building’s HVAC and DHW systems.

Choosing the right heat distribution system for a building (or network) is influenced by three main criteria:

  1. technical connection specifications;
  2. heat requirements of the building; 
  3. comfort preferences of the building’s occupants.

The more accurately you can balance those needs, the better the service you will provide to your end-users and the more energy efficiency you will achieve. Both of these factors are good for your business.

At Danfoss, we develop and produce all  major components for our substations and flat stations in-house. Because we manufacture the key components ourselves, you will benefit from optimized heat transfer and system control performance. Pressure, differential pressure, temperature and flow are integrated and automatically controlled on nearly all Danfoss substations.

Controllers without auxiliary power, electronic controllers, motorized control valves and energy meters ensure maximum comfort and energy efficiency. They also enable integration into higher-level control and monitoring systems.
