Kylmävesiverkot

Kylmävesiverkot, also known as cold water networks, are specialized district heating and cooling systems. Instead of delivering hot water for heating, these networks transport cold water at low temperatures, typically between 5 and 15 degrees Celsius, for cooling purposes. They are a key component of urban infrastructure in many regions, particularly those experiencing warm summers.

The primary function of a kylmävesiverkko is to provide chilled water to buildings for air conditioning. This chilled water circulates through a network of underground pipes, similar to traditional district heating systems. Buildings connected to the network receive the cold water, which then passes through heat exchangers to cool the air within the building. The slightly warmed water is then returned to the network to be re-chilled.

Kylmävesiverkot offer several advantages. They contribute to energy efficiency by centralizing cooling production, often utilizing more efficient methods than individual building units. They can also reduce the urban heat island effect by absorbing heat from buildings and releasing it at a more dispersed location, or by using sources like seawater or geothermal energy for cooling. Furthermore, they can improve air quality in urban areas by reducing the need for individual air conditioning units that release heat and refrigerants.

The development and expansion of kylmävesiverkot are part of a broader trend towards sustainable urban energy solutions. They are often integrated with renewable energy sources and smart grid technologies to optimize performance and minimize environmental impact.
