Investigation of air-source heat pump using heat pipes as heat radiator
International Journal of Refrigeration, 2018Abstract In this study, a concept of air-source heat pump using heat pipes as heat radiator system (ASHPP) for room heating was proposed. The heat pipes radiator was developed to replace the heating terminal equipment used in traditional heat pump plants. A tested room with artificial load was constructed and an experimental apparatus of ASHPP system

Experimental study of an improved air source heat pump
Energy Conversion and Management, 2004Abstract Although the advantage of an air source heat pump (ASHP) is self evident, all kinds of ASHPs available on the market have a deadly shortcoming that prevents their application in wider areas. They cannot run smoothly where the ambient temperature is very high in summer or extremely low in winter.

Self-optimizing Control of an Air Source Heat Pump
2019 American Control Conference (ACC), 2019Self-optimizing Control (SOC) is a method for finding appropriate controlled variables for which implementation of feedback control yields nearly-optimal operation regardless of variation in disturbances. The Jacobian estimation process in conventional SOC rely on an offline analysis of large amounts of steady-state data, which can be difficult in ...

Air source integrated heat pump simulation model for EnergyPlus
Energy and Buildings, 2017Abstract Air source integrated heat pump (ASIHP) is an air source, multi-functional space-conditioning unit with water heating function (WH), which can lead to significant energy savings by recovering condensing waste heat in the cooling season and providing dedicated or desuperheating heat pump water heating in the remaining months.

Air Source Heat Pumps under Northern European Climatic Conditions
1980The maritime climate of the islands and western coast of continental Europe is suitable for the use of air source heat pumps, working in the heating mode only, for domestic space heating. Field trials of several types of air to air and air to water heat pump systems in homes in Ireland are described.
