Heat pump is an eco-friendly way of exploiting energy from nature, i.e. heat pumps are one of the most cost-effective and healthiest ways of using alternative energy.
Heat pump is a device that takes heat from the environment and transmits it on higher temperatures in the heating system. By using a heat pump it is possible to take heat from the environment in a circular process, so that this heat can be used on a higher temperature level for heating, where the amount of heat is manifoldly higher than heating equivalent of electric power. For example, for 1kW of used electric power one gets 3-4kW heat energy, and in some cases even more.
Work of a heat pump can be briefly described in the following way:
Heat energy taken from the environment enters the evaporator of the pump. The pump contains gas R410 which takes over the energy. This gas maintains its state even on temperatures below zero.
Gas then enters the compressor and rises to a higher pressure, which leads to a significant increase in its temperature (mostly +90-95°C, but it can go even higher).
Thanks to delivery of heat energy, gas returns to the original temperature and then goes to the expansion vessel and valve, which brings pressure back to the initial state. After this, gas returns to the evaporator and the process begins again.
This type of heating has been used for several decades in the world. In Tokyo, Japan in 1932 one of the first heat pumps in the world was installed. Nowadays, more than million heat pumps are used for heating residential buildings across Europe, Canada and the USA. From all alternative heating systems, heat pumps have the biggest prospect. Heat pump is the only device with which man deceived the nature to get more than it is invested.
