Adsorption Gas Heat Pump Lab Tests

This study aims to investigate a fuel-fired Thermal Heat Pump (THP) technology to assess its uniform efficiency factor (UEF) potential. The Gas Technology Institute (GTI) Energy will serve as the subcontractor for this study. The THP concept is a gas-driven ammonia adsorption heat pump water heater concept in a packaged system. It incorporates a buffer tank and a sorption module that includes the reactor (thermal compressor) with a salt matrix sorbent and heat exchanger. The sorption module is a closed water system hermetically sealed with no moving parts, using ammonia as the refrigerant. The system size is anticipated to be similar to a typical residential 50-gallon gas storage water heater and is intended as a drop-in replacement for residential water heating. For this study, the "Beta" unit will be tested as recent improvements from the prior "Alpha" units have led to advancements designed to achieve a UEF greater than 1.2.
