virtausaukot

Virtausaukot, also known as vortex grinders or vortex tubes, are devices that separate the air in a stream into two streams of different temperatures using the principles of thermodynamics and fluid dynamics. The process begins with compressed air entering the tube, which then splits into two streams: one hot and one cold. This separation occurs due to the vortex effect created by a tangential inlet, which causes the air to spin rapidly. The hot air exits through the hot end of the tube, while the cold air exits through the cold end. The temperature difference between the two streams can be significant, with the hot stream often reaching temperatures close to the inlet air temperature, and the cold stream dropping to near ambient temperature. Virtausaukot are used in various applications, including refrigeration, air conditioning, and industrial processes, due to their simplicity, reliability, and energy efficiency. They are particularly useful in situations where a small amount of cold air is needed, as they do not require any moving parts or refrigerants. However, their efficiency and temperature difference are limited by the inlet air temperature and pressure, and they are not suitable for applications requiring large volumes of cold air.
