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 Heat Pumps for Building Heating and Cooling
2023Air Source Heat Pumps (ASHPs) are part of the solution to decarbonize the residential heating sector. The coefficient of performance (COP) is a measure of the instantaneous efficiency of a heat pump. The heat energy produced by an ASHP is deemed renewable if it meets a specified sustained COP over a period of time, e.g., a seasonal performance factor ...

Applied Thermal Engineering, 2019
Abstract The recent evolution of the Ground Source Heat Pumps (GSHPs) has initiated the debate whether it is economically feasible to install a GSHP as an alternative to an Air Source Heat Pump (ASHP). A typical house heating/cooling load for moderate climates is presented and discussed for comparison purposes. For this purpose, the thermal response

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.

Measurement and investigation into air source heat pump exergy
SPIE Proceedings, 2011This study applies the second law of thermodynamics to analyze the irreversibility of air source heat pump systems. By using both T type thermocouple wires to measure the inlet and outlet temperatures of key components in the system and using pressure transmitters to measure the high and low pressure of the experiment systems, we collect data and use
