Heat exchangers and the performance of heat pumps – Analysis of a heat pump database
Applied Thermal Engineering, 2011Abstract Heat pumping is a highly energy-efficient technology that could help reduce energy and environmental problems. The efficiency of a heat pump greatly depends on the individual and integral performance of the components inside. In this study, heat pump performance is investigated with a special focus on heat exchangers.

Possibilities of heat pumps for heating homes
Electrical Engineering, 1944Heat pumps are refrigerating systems in which the principal interest is in the heat given off by the condenser. A portion of this comes from the electric input to the compressor and the remainder from cooling an external source of heat, usually outdoor air.

Heat pumps are widespread units employed in the daily life whether a consistent amount of energy is available at a low enthalpic level (i.e. not suitable temperature). Their particular efficiency is shown by mean of a practical example where heat balances and operating conditions are thoroughly discussed.

Numerical Simulations of Heat Pumps and Heat Pump Systems
Advanced engineering, 2010Utilization of heat pumps is rapidly increasing during last few years in Europe. That is the consequence of European dedication to increasing the share of renewable energy in final energy consumption as well. Heating, ventilation and air-conditioning (HVAC) systems of buildings are responsible for about 40% of final energy consumption.
