Heat Pump – A New Type of Renewable Energy Source

In order to increase energy efficiency and achieve energy independence through the application of new technological solutions for energy supply to family homes, residential and commercial buildings, tourist and hospitality facilities, and various industrial plants, the company Energetika marketing, in collaboration with the Faculty of Mechanical Engineering and Naval Architecture in Zagreb, organized a seminar on the topic of heat pumps and promoted a new book from EM literature titled “Fundamentals of Heat Pump Application.”

As experts pointed out, significant atmospheric pollution in recent decades, especially today, necessitates the use of natural resources, which has also led to the emergence of advanced technological systems such as heat pumps that use 25 to 30 percent supplementary energy and draw 70 to 75 percent from renewable energy sources.
-Experimental research, publication issuance, popular presentations, and highly specialized practical application of technology related to heat pumps should help improve the understanding of this air conditioning device- emphasized Vladimir Soldo, an engineer from the Faculty of Mechanical Engineering and Naval Architecture in Zagreb. The seminar also discussed the theoretical foundations and application possibilities of heat pumps, with leading heat pump providers in the Croatian market presenting practical examples with technical solutions and economic analysis of operations: Bosch, Daikin, Danfoss, Robur, Vaillant, and Viessmann.

Attention was also drawn to the lack of adequate regulations regarding installation and the absence of laws in the areas of spatial planning and construction, water management, and mining. Representatives of the Ministry of Economy, Labor, and Entrepreneurship presented two regulations currently under development, which will regulate the encouragement of the application of renewable sources, including heat pumps, for obtaining thermal and cooling energy. Likewise, the need for the urgent introduction of incentive measures for the application of heat pumps and other renewable energy sources for cooling and heating air, as is the case in most European countries, was emphasized.

For example, in Germany, anyone wishing to equip their household with a heat pump to utilize heat from the ground, water, or air can count on support from the Federal Office for Economic Affairs and Export Control. -The cost of implementation is high, and without state incentives and benefits, these systems cannot function as there will be no significant savings- said Krešimir Pećar, an engineer from the Office of the Authorized Mechanical Engineer in Osijek.
