fjernkjølingsnett

Fjernkjøling, often translated as district cooling, is a system for refrigerating multiple buildings from a central source. This central source, or fjernkjølingsnett, distributes chilled water through a network of underground pipes to various consumers. The cooled water circulates through heat exchangers in the buildings, absorbing heat and then returning to the central plant to be re-chilled. This process significantly reduces the need for individual air conditioning units in each building, leading to energy savings and a smaller environmental footprint.

The primary components of a fjernkjølingsnett include a central cooling plant, insulated pipelines, pumping stations, and metering systems for each connected building. The cooling plant can utilize various methods for generating cold, such as absorption chillers powered by waste heat, conventional compression chillers, or even natural cooling sources like seawater or deep groundwater where available. The distribution network is designed to minimize heat gain during transport, ensuring efficient delivery of chilled water to the end-users.

Benefits of implementing fjernkjøling include reduced electricity consumption, lower greenhouse gas emissions compared to individual cooling systems, and improved urban air quality due to fewer rooftop units. It also offers greater reliability and can be integrated with district heating systems to create a combined utility service. Fjernkjølingsnett are becoming increasingly popular in urban environments seeking sustainable and efficient cooling solutions.
