The Panasonic Gas Heat Pump VRF, which was designed in the 1980s to reduce the use of electricity in Japan, is the natural choice for commercial projects, especially for projects where power restrictions apply. The GHP (internal combustion) engine varies the engine speed to make building load functions comparable with inverter type air conditioners.
Since it uses waste heat from a gas engine, the heating start-up is very fast. The room can be heated almost instantly. There are also very few defrosting cycles, so a constant flow of hot air can be supplied compared with EHP systems.
Low Power Consumption
Also, GHP systems do not use any electricity other than that for driving fans or other auxiliary devices, so the power consumption is very low compared with EHP systems. Of course, ordinary power consumption is also reduced, so it helps to significantly cut the power peak during seasons when the temperature often fluctuates.
The Difference between GHP and EHP
The advanced Panasonic GHP VRF system offers increased efficiency and performance across the range. Now more powerful than ever before, it can connect up to 48 indoor units. Improvements include increased part load performance, reduced gas consumption with a Miller-cycle engine and reduced electrical consumption by using DC fan motors.
