Absorption Cycle Heat Pump Integration for Locally Integrated Energy Sector

Performance Study and Energy Saving Mechanism Analysis of an Absorption/mechanical Hybrid Heat Pump Cycle

A hybrid heat pump cycle of the heat amplifier type integrating a booster compressor between the generator and the condenser for distributed heating is simulated and analyzed. The interrelation between the two sub-cycles and the hybridization principle are explored. The theoretical analysis is demonstrated by a H2O/LiBr based hybrid cycle simulation. Investigation of the interaction mechanisms ...

A Concept for an Integrated R744 Heat Pump for Low-heating-energy Buildings

In low-heating-energy buildings heat pumps have become an attractive heating system due to a notable reduction of the space heating requirements and the introduction of low temperature heating systems. Comfort cooling becomes also more important, especially in lightweight buildings with large south-oriented windows, which partially tend to overheat in summer. A heat pump has the unique feature ...

The Double-Effect Regenerative Absorption Heat Pump: Cycle Description and Experimental Test Results

Enhancements of an Integrated Simulation Tool for Ground- Source Heat Pump System Design and Energy Analysis

Ground-source heat pump (GSHP) utilizes the immense renewable storage capacity of the ground as a heat source or sink to provide space heating, cooling, and domestic hot water. GSHP systems are generally comprised of water source heat pumps and ground heat exchangers (GHX). Vertical closed-loop GHX is used predominantly in commercial and institutional applications. Closed loop GHX consists of a...

Optimum Design of an Absorption Heat Pump Integrated with a Kraft Industry using Genetic Algorithm

In this study the integration of an absorption heat pump (AHP) with the concentration section of an industrial pulp and paper process is investigated using pinch technology. The optimum design of the proposed water-lithium bromide AHP is then achieved by minimizing the total annual cost. A comprehensive optimization is carried out by relaxation of all stream pressure drops as well as heat excha...
