What is GHP
The Gas Heat Pump System (GHP)
Panasonic Gas Heat Pump is a direct expansion system with compressor as same as VRF system. Gas engine is used as driving source of compressor instead of electric motor. This gas engine compressor drive has 2 advantages:
- Waste heat from the gas engine available
- No need for motor power consumption thanks to gas engine
How GHP Systems Work
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.
Advantages of GHP
Fast and Powerful Heating
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.
Significantly reduced power consumption
Reduces power loadings within a building especially during peak periods
The GHP VRF systems have the lowest nitrogen oxide emissions. In a pioneering development, the Panasonic GHP features a brand new lean-burn combustion system that utilizes air fuel ratio feedback control to reduce NOx emissions to an all time low.
