Effective Energy Use Reduces Running Costs

This system recovers exhaust heat from a motor that drives a generator, and then effectively utilizes it as a heat source. Since medical facilities require a large energy consumption per unit floor area for various purposes including air conditioning, hot-water supply, steam for sterilization, lighting, medical equipment, and powered machinery, installing an optimally-sized cogeneration system (CGS) can reduce overall running costs.

Example Installation of Cogeneration System (for extension of a hospital)

Overview

Location Hokkaido
Total floor area Approx. 10,500m2 (existing) + 6,500m2 (extension)
Beds Approx. 250
Background for Installation Since used for individual sickrooms and the outpatient examination department, the extension is unlikely to add a new revenue stream. To offset an increase in running costs, two cogeneration systems with the power of 150kW each are installed.
