TY - JOUR AU - Muszynski, Tomasz AU - Jakubowska, Blanka AU - Andrzejczyk, Rafal PY - 2019 TI - The impact of environmentally friendly refrigerants on heat pump efficiency JF - Journal of Power Technologies; Vol 99 No 1 (2019) KW - heat pump; heat exchangers; refrigerants; energy efficiency N2 - The article discusses the issue of heat pump simulation. The proper design of the equipment and its proper operation allows for lower operating costs. Exact technical and economic analysis allows for the selection of system components with the highest possible efficiency and therefore lower energy demand. The use of systems based on environmentally friendly refrigerants can ensure a long product life, which is associated with a more favorable ie. the shorter payback period of the investment made. In addition, the proper design process of equipment allows optimizing its operation. In times of rapidly increasing share of energy costs in the total cost of investment, it is worthwhile to consider the use of innovative solutions and benefit from tailor-made solutions to specific operating conditions.
