Alternative and green energy

Mi is az a hőszivattyú? Amint azt a neve is mutatja a hőszivattyú valaminek a „szállítására” szolgál, ám egy hagyományos vízpumpával ellentétben ez nem egy bizonyos közeget (például vizet vagy glikolt), hanem hőt szállít. Ahogyan a szivattyúkat a gravitáció leküzdésére és a keringetett közeg magasabb szintre történő emelésére használjuk, a hőszivattyút is hasonló céllal alkalmazzuk.

With recuperator – or mechanical ventilation system – it is possible to keep the air clean and fresh in the building, while the system prevents the escape of heat energy.

How the heat pumps work?

Heat pump is a commonly used alternative heating system, but yet most people still don’t know, how it operates:

As all the pumps, the heat pump transports substance as well. For heat pumps this substance is the heat. As we use the pumps to overcome gravity and pump the circulating liquid to a higher level, the heat pump can also be used for the same purposes.

In this case, the higher level becomes a the higher temperature, and the lower level is the cooler temperature. The heat pump’s aim is to deliver heat from a cooler location (such as soil or groundwater) to a warmer location, such as floor heating, wall heating or radiator network.

Heat pump operation in details

The heat pump system is best compared to an inverted refrigerator. Follow along  the cooling process:

A bottle – containing liquid at room temperature – is placed into the refrigerator. The warm liquid starts to heat up, so the air in the refrigerator warms and reach the 6°C. Thereafter, the walls of the refrigerator absorb heat, and lower the inner temperature back to 4 ° C.

Subsequently, the refrigerator passes the removed heat at a higher temperature to the envoriment through a cooling coil, located on the back of the refrigerator, which is much hotter than the 4-6 ° C in air stored indoors.

Building on this analogy we could say, that the refrigerator’s cooler, inner surface is the collector of the heat pump, and the coolig coil is corresponded as the building’s heating network (wall heating, floor heating etc. ).”
