High concentration NH<sub>3</sub>/H<sub>2</sub>O is suitable for Kalina cycles used for the recovery of low grade heat. Plate heat exchangers (PHEs) are compact and reduce the charge of working fluid. This paper investigates the condensation of NH<sub>3</sub>/H<sub>2</sub>O with NH<sub>3</sub> mass concentrations of 80%-96%. The vapor and...

The development of affordable magnetocaloric materials (MCM) with a giant magnetocaloric effect (MCE) has brought magnetocaloric heat pumps a step closer to commercialization. The narrow temperature range in which these materials exhibit a large MCE demands the use of several materials with Curie temperatures covering the temperature span of...

Ocean Thermal Energy Conversion (OTEC) produces electricity using the temperature difference between warm surface and cold deep-sea water. OTEC systems in literature only limitedly consider seasonal seawater temperature<br/>variations and thus might not be adequately sized for off-design conditions. This potentially leads to techno-economically...

This study optimizes the district heating network side of a high temperature community heating system powered by decentralized solar collectors and seasonal thermal energy storage (STES). Six network configurations are considered which have the potential to improve system performance compared to a base scenario. The base scenario consists of a 2...

Within the agriculture sector, drying of food and flowering products is a required production step. Most companies use hot air dryers where the heat is obtained by combustion of natural gas. This paper proposes a heat pump assisted drying system as an alternative. Flower bulb carrying boxes containing just harvested products have been...

High concentration NH3/H2O is suitable for Kalina cycles used for the recovery of low grade heat. Plate heat exchangers (PHEs) are compact and reduce the charge of working fluid. This work investigates the absorption of NH3/H2O in a PHE, which has a weight concentration of 96%. Being different from normal absorption systems, the concentration...

Seasonal thermal energy storage (STES) systems in combination with heat pumps can significantly reduce the impact of peak loads in large scale district heating systems and allow for the application of renewable heat sources in these networks. This paper investigates technologies with the highest potential for implementation in large scale...

Buildings consume 40% of the total global energy and contribute to over 30% of all CO2 emissions. Space heating forms a significant part of energy consumption in buildings. A possible solution is to recover waste heat from sewage and to upgrade its exergy using a heat pump. Polymers reduce cost and energy required for manufacturing the heat...

A comparative study for a representative case district in the Netherlands with around 2500 dwellings has been executed with the purpose of identifying the best solution for a Low Temperature District Heating (LTDH) with Low Temperature Geothermal Heat (LTGH) as the main heat source. The district is presently connected to the Dutch gas network....

This paper investigates NH<sub>3</sub> condensation in a plate heat exchanger by visualizing the flow patterns and measuring heat transfer coefficients and frictional pressure drop. Visualization experiments were conducted between 20 and 100 kgm<sup>−2</sup>s<sup>−1</sup>. Full film flow takes place at large mass fluxes and intermediate mass...

This paper develops predicting models for NH<sub>3</sub> condensation in plate heat exchangers based on the experiments of flow patterns, heat transfer coefficients and frictional pressure drop previously reported by the authors. The aim is to provide design methods of compact plate condensers used in NH<sub>3</sub> systems, which are not...

Heat pumps can efficiently upgrade waste heat from the industry and in that way reduce emissions. One of the main reasons why heat pumps are not applied to a greater extent in industry are large payback periods. Compression–resorption heat pumps (CRHP) enhanced by wet compression are considered a very promising option that can have higher...

Heat pumps can drastically reduce energy requirements in industry. Operating a compression resorption heat pump with an NH<sub>3</sub>-CO<sub>2</sub>-H<sub>2</sub>O mixture has been identified as a promising option that can have an increased performance compared to only NH<sub>3</sub>-H<sub>2</sub>O. In this paper an important process of the...

Compression-resorption heat pumps (CRHP) utilizing wet compression are a very promising option to upgrade waste heat from industry. CRHPs have the potential to have higher coefficient of performance (COP) than the traditionally used vapour-compression heat pumps (VCHP). However, commercial solutions utilizing wet compression are not available...

The corrugation channels of plate heat exchangers enhance the heat transfer and complicate the prediction of heat transfer coefficients and frictional pressure drop. This paper reviews the heat transfer and frictional pressure drop correlations for condensation in plate heat exchangers, and classifies the correlations into basic forms. An...

Unfavorable transport properties have always been pointed out as the key factors that hinder the application of ammonia/ionic liquids (NH <sub>3</sub> /ILs) in absorption cycles, while heat and mass transfer of these new fluids in components have been rarely reported. In this study, a corrugated plate heat exchanger is selected as the...

This work presents the concept of a photovoltaic (PV)-powered solar chimney. We modeled and experimentally studied the integration of a PV system within a naturally ventilated façade (NVF), attempting to use the inherent cavity as a ventilation channel to transfer heat. Thermodynamic models were created to study the thermal and, therefore,...

For absorption refrigeration, it has been shown that ionic liquids have the potential to replace conventional working pairs. Due to the huge number of possibilities, conducting lab experiments to find the optimal ionic liquid is infeasible. Here, we provide a proof-of-principle study of an alternative computational approach. The required...

To use high-temperature waste heat generated by diesel engines for onboard refrigeration of fishing vessels, an ammonia-based double-effect vapor absorption refrigeration cycle is proposed. Non-volatile ionic liquids are applied as absorbents in the double-effect absorption system. In comparison to systems using ammonia/water fluid, the...
