Kiertovesilämmönvaihtimet

Kiertovesilämmönvaihtimet, often referred to as plate heat exchangers, are devices designed to efficiently transfer heat between two fluids. In heating systems, they typically separate the primary heating circuit, such as a district heating network or a boiler loop, from the secondary circulation loop that distributes heat throughout a building. This separation is crucial for several reasons. Firstly, it protects the building's internal heating system from potential contaminants or pressure fluctuations present in the primary circuit. Secondly, it allows for precise control of the temperature delivered to the building's radiators or underfloor heating.

The operation of a kiertovesilämmönvaihdin relies on a series of thin, corrugated metal plates. The hot fluid from the primary circuit flows through alternating channels, while the cooler fluid from the secondary circuit flows through the remaining channels. The corrugations on the plates create turbulence, enhancing heat transfer efficiency. As the fluids pass each other, heat is transferred from the hotter fluid to the colder fluid through the plate material. This process heats the secondary circuit's water, which is then circulated to provide warmth within the building. Kiertovesilämmönvaihtimet are compact, modular, and can be easily maintained or expanded. They are a common component in modern building services, contributing to energy efficiency and system reliability.
