Commercial Gas Heat Pump Technology Overview

This document is a guide on commercial gas heat pump (GHP) technology, focusing on its efficiency and operational benefits. It explains how GHPs work by drawing thermal energy from outside air and utilizing natural gas combustion to drive the heat pump system. The guide details two types of GHPs available for commercial use: gas-engine driven heat pumps (GEHP) and gas absorption heat pumps (GAHP). GEHPs provide heating and cooling using a natural gas engine, while GAHPs utilize ammonia as a refrigerant, which has zero global warming potential. The document also presents a success story from Arleta Manor in Toronto, where GAHP units effectively meet hot water needs and reduce carbon emissions. Additionally, it outlines the advantages of GHPs, including lower operational costs, environmental benefits, ease of conversion to low-carbon fuels, and high efficiency in cold climates. The North American Gas Heat Pump Collaborative is introduced as a key player in promoting GHP technologies.
