Booster heat pumps and central heat pumps in district heating
Applied Energy, 2016Abstract District heating (DH) enables the utilisation and distribution of heating from sources unfeasible for stand-alone applications and combined with cogeneration of heat and power (CHP), has been the cornerstone of Denmark’s realisation of a steady national primary energy supply over the last four decades.

A DEHUMIDIFYING HEAT PUMP FOR GREENHOUSES
Acta Horticulturae, 2012In heated greenhouses, attempts have been made to produce potted plants while reducing the amount of energy used. In fact, improvements in greenhouse structure and equipment (double walls, etc.) have led to better insulation and tightness. However, this tightness induces microclimatic changes, especially on night time humidity levels.

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.
