In hospitals, a stable power supply 24 hours a day, 365 days a year is essential for maintaining patient life and the operation of medical equipment. Power outages can have serious impacts on the provision of medical services and may threaten patient safety. GHP, powered by gas engines, can reduce power consumption and help mitigate summer electricity peaks. Furthermore, if gas supply continues, some models can operate even during power outages, making them effective as part of BCP measures. 【Usage Scenarios】 - Hospitals - Medical facilities - Nursing facilities 【Benefits of Implementation】 - Reduction of electricity costs during peak power times - Use as a backup power source during outages - Reduction of CO₂ emissions (situation-dependent)

• Air Conditioning System

In office buildings, the demand for electricity increases during the summer, making peak power management an important issue. At the same time, there is a need to reduce CO₂ emissions to lessen environmental impact. GHP contributes to solving these challenges by reducing electricity consumption and using gas as fuel. 【Usage Scenarios】 - Air conditioning in office buildings - Measures to cut peak electricity demand - BCP (Business Continuity Planning) measures 【Benefits of Implementation】 - Suppression of peak electricity demand - Reduction of CO₂ emissions (situation-dependent) - Continuous operation during power outages (for certain models)

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.
