Abstract:
This article presents the components of heat pumps, cooling cycles, an example of heat pump application and its economy. The emphasis in the article is to show the energy efficiency of the heat pump in relation to the corresponding boiler plants. An economic analysis of individual solutions was performed according to economic criteria on the basis of which the proposed variants can be selected. Those analyzes assume technical concepts that directly determine the degree of profitability of the selected system. Such analyzes have usually never been done for classic energy systems, so since we were forced to do them without preparation, the transition to new technological concepts of obtaining heat energy was and still is slowed down.

Key words:
heat pumps,energy,efficiency,economy,boiler plants.
