jäähdytysvoimalaitos

A jäähdytysvoimalaitos, or cooling power plant, is a type of power generation facility designed to primarily produce chilled water for industrial or commercial use, rather than electricity. While they may generate some electricity as a byproduct, their main function is cooling. These plants are distinct from conventional thermal power plants which focus on producing heat and electricity.

The core principle behind a jäähdytysvoimalaitos involves refrigeration cycles. They typically use large-scale chillers, often driven by steam turbines or electricity, to lower the temperature of water. This chilled water is then circulated through a network of pipes to various consumers. Common applications include air conditioning for large buildings, industrial processes requiring precise temperature control, and even food preservation.

The energy source for driving the chillers can vary. Some plants utilize waste heat from other industrial processes or even from the operation of an associated electricity-generating power plant, making them a form of cogeneration. Others may rely on dedicated fuel sources. The efficiency of a jäähdytysvoimalaitos is often measured by its coefficient of performance (COP), which indicates the ratio of cooling provided to the energy consumed. These facilities play a crucial role in urban infrastructure and industrial complexes, providing essential cooling services in a centralized and often more efficient manner than individual cooling systems.
