Problems solved by technology

Moreover, most of the primary energy is produced by fossil fuels which result in the emissions of gasses which harm the environment.
One drawback to LiBr/water absorption water heater systems is that they are unable to operate at typical water heating temperatures due to solution crystallization hazards.
Crystallization results in interruption of machine o...

[0062]The absorption water heating systems described herein were modeled to show that the proposed systems would enable the use of LiBr-based absorption water heating systems for residential use and eliminate or minimize the risk of crystallization at the absorber. An existing absorption cycle software package, ABSIM, was chosen to investigate single-effect LiBr (absorption water heater) AWH performance. The model treats the heat exchange between the cycle and its surroundings according to several user-specified options differentiated by the required user input. These include ‘UA’, effectiveness or temperature difference options. The model incorporates a number of working fluid combinations including LiBr / water and ammonia (NH3) / water.

[0063]A model for a conventional 1.6 kW single-effect absorption heat pump system where the process water flows from the condenser to the absorber was developed using ABSIM. A model for an exemplary absorption heat pump system where the process water f...

Abstract

An absorption heat pump system that can include a first assembly, a second assembly, and a thermal coupler is disclosed herein. The first assembly can include a condenser and an evaporator. The second assembly can include an absorber, a desorber, and a heat exchanger. The thermal coupler can include a first gas inlet, a second fluid inlet, and a mixed fluid outlet. The system can be configured with a first gas outlet of the desorber in fluid communication with the first gas inlet of the thermal coupler, and the mixed fluid outlet of the thermal coupler in fluid communication with a mixed fluid inlet of the evaporator. The system can also include a coolant absorber inlet and outlet on the absorber and a coolant condenser inlet and outlet on the condenser, with the coolant absorber outlet in fluid communication with the coolant condenser inlet.

Description

STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0001]The United States Government has rights in this invention pursuant to Contract No. DE-AC05-00OR22725 between the United States Department of Energy and UT-Battelle, LLC. The Government has certain rights in the invention.FIELD OF THE INVENTION[0002]This disclosure relates to the field of heat pumps, and more particularly to apparatus and methods of using absorption heat pump systems.BACKGROUND OF THE INVENTION[0003]According to the 2009 Buildings Energy Data Book, space cooling and heating, as well as water heating, use 49.8% and 25.2% of primary energy consumed in U.S. residential and commercial buildings, respectively. (U.S. Department of Energy's Office of Energy Efficiency and Renewable Energy, 2009a). Moreover, most of the primary energy is produced by fossil fuels which result in the emissions of gasses which harm the environment. Thus, it has become more important than ever to develop energy-efficient and en...
