Abstract

Here, the objective of this work is to simulate a single effct (SE) ammonia-water heat pump for domestic water heating, with innovative aspects for cycle simulation and eventual implementation. Seasonal temperature variations demand verfication of distillation column viability. For the given application and temperature ranges, it is found that some variables need to be controlled if the same column is to be used all year round. In addition, a number of simplifications are considered in this work: an advanced evaporator requireing minimal gas flow and surface area, subcooling at two crucial spots of the cycle and the viability of some pump designs to assuage cavitation issues.

Compact sieve-tray distillation column for ammonia-water absorption heat pump: Part 1 -- Design methodology

Conference Anand, G ; Erickson, D C

The distillation column is a key component of ammonia-water absorption units including advanced generator-absorber heat exchange (GAX) cycle heat pumps. The design of the distillation column is critical to unit performance, size, and cost. The distillation column can be designed with random packing, structured packing, or various tray configurations. A sieve-tray distillation column is the least complicated tray design and is less costly than high-efficiency packing. Substantial literature is available on sieve tray design and performance. However, most of the correlations and design recommendations were developed for large industrial hydrocarbon systems and are generally not directly applicable to the compactmore »« less
Waste Heat Recovery and Recycling in Thermal Separation Processes: Distillation, Multi-Effect Evaporation (MEE) and Crystallization Processes

Technical Report Dada, Emmanuel A ; Panchal, Chandrakant B ; Achenie, Luke K ; ...

Evaporation and crystallization are key thermal separation processes for concentrating and purifying inorganic and organic products with energy consumption over 1,000 trillion Btu/yr. This project focused on a challenging task of recovering low-temperature latent heat that can have a paradigm shift in the way thermal process units will be designed and operated to achieve high-energy efficiency and significantly reduce the carbon footprint as well as water footprint. Moreover, this project has evaluated the technical merits of waste-heat powered thermal heat pumps for recovery of latent heat from distillation, multi-effect evaporation (MEE), and crystallization processes and recycling into the process.

Development and Validation of a Gas-Fired Residential Heat Pump Water Heater - Final Report

Technical Report Garrabrant, Michael ; Stout, Roger ; Glanville, Paul ; ...

For gas-fired residential water heating, the U.S. and Canada is predominantly supplied by minimum efficiency storage water heaters with Energy Factors (EF) in the range of 0.59 to 0.62. Higher efficiency and higher cost ($700 - $2,000) options serve about 15% of the market, but still have EFs below 1.0, ranging from 0.65 to 0.95. To develop a new class of water heating products that exceeds the traditional limit of thermal efficiency, the project team designed and demonstrated a packaged water heater driven by a gas-fired ammonia-water absorption heat pump. This gas-fired heat pump water heater can achieve EFs ofmore »« less

Simulation and performance analysis of an ammonia-water absorption heat pump based on the generator-absorber heat exchange (GAX) cycle

Conference Grossman, G ; DeVault, R C ; Creswick, F A

A computer simulation has been conducted to investigate the performance of an absorption heat pump, based on the Generator-Absorber Heat Exchange (GAX) cycle employing ammonia-water as the working fluid pair. The particular feature of this cycle is the ability to recover heat from the absorber and employ it to partially heat the generator, thus improving the COP. In the present study, a detailed simulation has been conducted of one of the preferred configurations for the cycle. A modular computer code for flexible simulation of absorption systems (ABSIM) was employed. Performance parameters, including COP and capacity, were investigated as functions ofmore »« less

Design of cross-flow condensers for ammonia-water absorption heat pumps

Conference Garimella, S ; Coleman, J W

A procedure for the design of air-cooled cross-flow condensers for absorption space-conditioning systems was developed in this study. The refrigerant under consideration is a binary fluid mixture of ammonia and water, which is one of the primary fluid pairs being considered for absorption heat pumps. The effect of a two-component mixture on tube-side temperature profiles was investigated in detail. Several alternative fin types were considered for the air side. A comparison of the performance of condensers with these different fin types was made through the computation of heat exchanger mass for equivalent heat duties. Within the limitations of the availablemore »« less
