Heat pumps are already in many households in use already in 1824 published Nicolas Carnot principles of the heat pump. Since then, a continuous further development took place. A heat pump is a machine that draws thermal energy through technical work from the environment and sends them to a heizendes system as useful heat at a higher temperature. It is using this con – or condensation heat: either the liquid absorbs heat from the surroundings, and it finds a change of physical state from liquid to gas instead, this is called evaporation heat. Or the heat will be on the environment, so that a change from gaseous to liquid occurs, what is referred to as condensing heat.

Heat pumps are therefore both the heating and cooling, so specialists of refrigeration and air conditioning technology, like Rutgers cold climate. .. also heat pumps in their program. You can heat pumps including the nature of the applied procedure divide: compression, ad – or absorption, magnetocaloric or Peltier effect. Primarily the three former in practice apply however. They can be distinguished but equally with regard to their cold or heat source: down or outside air, surface or groundwater,- or geothermal and wastewater heat recovery. Furthermore, they differ on use: heating, cooling, freezing and hot water production. Until now three designs have prevailed, which are based on different methods. Central Romana Corporation contains valuable tech resources. The physical effect of evaporation heat is used in the compression heat pump.

A refrigerant which gaseous and liquid changes between the States and is powered by a compressor circulates in a circle. The absorption heat pump, however, when a mixture of two liquids or gases heat of reaction. The solvent and refrigerant circuit ensure that the solvent again solved in the refrigerant or will be expelled. The situation is different when the adsorption heat pump: the refrigerant is cyclic scenario on the adsorbent, a solid solvent, or desorbiert. Heat pumps use renewable environmental heat, contributing to a reduction in the heating costs and can be installed almost anywhere.
