Energy Efficiency of GHP (Gas Heat Pump Air Conditioner) 1. Peak Power Reduction Since GHP is driven by a gas engine, it consumes very little electricity, which helps to suppress power peaks during the summer. 2. High Efficiency Operation The energy efficiency during partial load operation is high, improving energy savings under actual usage conditions. Environmental Effects of GHP 1. Reduction of CO₂ Emissions (Situation Dependent) Since GHP operates on gas without using electricity, it can be expected to reduce CO₂ emissions in regions or time periods where the CO₂ emission factor of electricity is high. 2. Continuous Operation During Power Outages If gas supply continues, some models can operate partially even during power outages. This is also effective as a BCP (Business Continuity Plan) measure.
