— a heating device that heats the room with the help of a coolant. This happens with the help of convection, a process in which air flows change: heated rises up, and cold takes its place.
The thermal efficiency of the convector is determined by the temperature of the coolant, the size of the heat exchanger and the type of convection, which is natural and forced. With natural convection, the movement of air occurs according to the laws of physics — cold air descends into the convector, heats up there, and already warm air rises. This type of convectors is cheaper, easier to install, but their thermal efficiency is not very high and in most cases it is used as additional heating.
With forced convection, there is a tangential fan in the convector, which forcibly drives cold air through the heat exchanger and blows warm air upwards. Such convectors are more expensive, require the laying of electrical communications to the convector and the installation of a control module. However, such convectors are much more efficient and can heat large areas with smaller dimensions.
