The heat pump system is a technology that makes an important contribution to mankind in many applications including the tourist sector, health sector, domestic sector, industrial sector, etc. Without heat pump systems our mankind's existence would be difficult despite 19% of the total electrical power is consumed to operate these heat pumps.
The use of these systems driving power in an inefficient way is excessive of important resources and increase the universal heating. Almost universal heating results from heat pump systems introduced from producing power to derive these systems, but enough part produced from the rejection of some types of refrigerants. The present study illustrates the methods that the heat pump system efficiency can be increased hence decreasing the universal effect on the environment. A case study representing heat pump strategy for energy saving is given.
