What is GHP?
The Panasonic Gas Heat Pump (GHP) VRF System is a direct expansion system with the same compressor as an electric VRF system. A gas engine is used as the driving source for the compressor instead of an electric motor.
Cost Reductions through Use of a Gas Engine
Significantly Reduced Power Consumption
GHP systems do not use any electricity other than that for driving fans or other auxiliary devices, so their power consumption is very low compared to EHP systems. Of course, ordinary power consumption is also reduced.
Significant Cuts in Power-Receiving Equipment Costs
As GHP systems consume less power than EHP systems, they can significantly cut power-receiving equipment repair costs and be installed with minimal investment. They can also be used for air conditioning in non-electric areas.
Waste Heat from Gas Engines can be Used for Domestic Hot Water (DHW)
The rejected heat from the engine is available for DHW production and can supply up to 46 kW of hot water at 65°C. DHW at 65°C is also ready to use without additional electric heaters.
High Efficiency through Trustworthy Design and Technology
1 High Blast Efficiency
A propeller with three blades provides high blast efficiency.
2 L-Shape Heat Exchanger
An L-shape heat exchanger provides a large surface area to ensure optimal operational efficiency.
3 Exquisite Partial Load Control
Start/stop loss is decreased by expanding the area where continuous operation is possible. This ensures good annual operational efficiency at low partial load.
Mechanisms for High Operational Efficiency and Energy-Saving Performance
Improved Engine Torque Results in Reduced Energy Costs
As the GE3 Series takes up a large engine operating area at low speed, it maintains high torque even under low load during low RPM to demonstrate excellent operational control capability. Compared to the previous GE2 Series, the GE3 Series achieves excellent operational performance with lower fuel consumption.
Increased Engine Pulley Diameter for Higher Efficiency
Compared to that on the previous GE2 Series, the engine pulley on the GE3 Series has a larger diameter to optimize the ratio between compressor speed and engine speed. The larger diameter improves performance under partial load and reduces the number of on/off rotations.
Improved Compression Efficiency through an Upgraded Compressor
The rotary compressor used in the GE3 Series has a smaller clearance between the roller and the outer circle, preventing the compression leakage of refrigerant and ensuring reliable compression. Further, increasing the size of the suction path has reduced suction pressure loss to ensure high compression efficiency even under high load (high speed operation). This contributes to quick temperature adjustments and lower operational costs.
Environmentally Friendly
Low Environmental Impact
EHP VRF systems that run on electricity can lose up to approx. 60% of power during generation and transmission. On the other hand, Panasonic GHP VRF systems run on gas, which means there is no energy loss during transmission. As a result, compared to EHP systems, Panasonic GHP VRF systems can significantly reduce environmental load.
Low CO₂ Emissions
Panasonic GHP VRF systems run on natural gas, the energy source which generates the lowest amount of CO₂ when combusted. Further, as these systems do not generate large amounts of CO₂ from electricity generation at thermal power plants like EHP VRF systems do, they can drastically reduce CO₂ emissions.
Low NOx Emissions
The GHP VRF systems have the lowest nitrogen oxide (NOx) 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.
