4 History of SANYO GHP Development Increase in electric power demand & oil crisis Japan Government starts the energy leveling policy Apr.1981 Development Apr Apr.1985 Mar Production of GHP prototype starts with Tokyo Gas. Participated in the national project of Gas Cooling Technology. Started joint development of GHP with major gas companies Worlds First! Released 15HP GHP in Japan Three manufacturers entered into GHP market Achieved total 1 million HP in Japan Jul.2000 JIS Establishment Released New Refrigerant (R407C) Apr.2002 Low NOx mode less than 100ppm Sep.2003 Released Overseas J2 model (8HP~20HP) 2 million HP installed in Japan 2004 Worlds First!

EER = 1,67 (with hot w.)* Plain calculation (with electric = gas): EER = 1,41 (no hot w.) EER = 1,92 (with hot w.) * Calculated backwards for comparison with electric AC: EER = 4,18 ** ECO-label directive 23

30 Periodic Maintenance hours engine operation A car driving with 50 km/h average speed 30

31 GHP Service Intervals All GHP models and sizes have a service interval of hours. Generally the lifetime is calculated for max hours. If the GHP is used for cooling & heating all year round take care about operating hours! One year = hours. If the project will result in such a kind of operation the GHP is not suited for this need as it would mean replacement of the unit after only 3,5 years. Normally operating hours should not exceed hours a year! It is recommended to use the timer functions for stopping operation at weekend, holiday, nighttime etc. As GHP basic operation principle is to keep stable room temperatures by smooth operation (low rpm.) it is very important to keep in mind this point for economic long time operation.
