This paper presents an overview of control systems for heat pumps, and more specifically, a
critical review of control methodologies for thermally activated absorption heat pumps. The …

The global energy demand is increasing at alarming rates. Until 2040, most of this energy
will still be coming from fossil fuels, which generate pollution and global warming, thereby …

There is a pressing need to decarbonize our energy sector to limit the effects of climate
change. Electrification in the buildings and transportation sectors is being proposed as a …

Absorption systems have considerable potential to fight global warming and help transition
to renewable energies. These machines use multifunctional exchangers (heat and mass …

This paper presents the results from an experimental evaluation of a small-scale, waste-heat
driven ammonia-water absorption chiller. The cycle is thermally driven, using the waste heat …

Microchannel condensers have the potential to improve system level efficiency by
increasing the heat transfer coefficient because of the small hydraulic diameters. In addition …

An investigation was conducted to explore the potential use of a Natural Gas Absorption
Heat Pump (GAHP) for heating and cooling. This investigation involved experiments and …

A standalone absorption chiller based on microchannel heat exchanger technology was
developed with a cooling capacity of 7 kW. A review of recent advances in microscale heat …

Ammonia-water absorption-resorption heat pump (ARHP) is a promising technology for
promoting efficient utilization of low-temperature thermal for space heating. This paper …

The trend to reduce CO2 emissions in cooling processes has made it possible to increase
the alternatives for integrating solar energy with thermal equipment whose viability depends …
