Modelling Heat Pumps with Variable EER and COP in EnergyPlus: A Case Study Applied to Ground Source and Heat Recovery Heat Pump Systems

Ground-source (geothermal) Heat Pumps

Performance Assessment of a Variable Capacity Air Source Heat Pump and a Horizontal Loop Coupled Ground Source Heat Pump System

This study evaluates the performance of air source heat pump (ASHP) and ground source heat pump (GSHP) systems individually and as part of their associated heating and cooling distribution systems in two semi-attached houses. Over the monitoring period, the performance of both heat pumps exceeded manufacturer and EnerGuide ratings, with Coefficients of Performance (COPs) above 5 in the cooling ...

A model of groundwater seepage and heat transfer for single-well ground source heat pump systems

In China, for the limitation of land, many buildings intending to utilize ground source heat pump systems install “single-well” systems, which drill only one well for both the pumping and reinjection of the groundwater. A model of groundwater seepage and heat transfer for single-well ground source heat pump systems has been established and validated against the experiment conducted in Denmark. ...

Simulation and Optimization of Ground Source Heat Pump Systems

Assessment and Deployment of Ground Source Heat Pump for Air Pollution Reduction in Tehran, Iran

The use of renewable energies, especially in metropolises has led to a reduction in environmental pollution and greater access to clean, renewable and sustainable energy. This paper evaluates the effectiveness of a national plan adopted by the Tehran city council for reducing air pollutions. This plan is designed to increase the share of renewable energies in residential buildings. This study a...
