Gas Heat Pumps - GHP

ECO G - Gas VRF systems

Panasonic’s extensive gas heat pump range includes the ECO G and ECO G Multi 3 series. The commercial gas VRF heat pump range is leading the industry in the development of efficient and flexible systems, making it a natural choice for projects where there are power constraints or where CO2 emissions need to be reduced.

As expected, gas-fired VRF systems have the highest reliability ratings in the industry and offer a range of customer benefits. The torque and speed control features of gas heat pump engines are compatible with the control features of electric inverter VRF systems. As a result, gas heat pumps offer individual and efficient control and deliver the same performance expected of electric VRF systems.

Easy to install

Advanced gas-fired VRF systems deliver increased performance and efficiency. Now with even higher capacities and the ability to connect up to 48 indoor units. Improvements also include higher part-load efficiency, reduced gas consumption through the use of Miller Cycle engines and reduced electricity consumption through the use of DC fan motors.

High-efficiency VRF systems using R410A refrigerant

High-performance work

All models are equipped with high-class heat exchangers that ensure high system efficiency and one of the highest energy efficiency rates on the market.

Unmatched energy efficiency

Panasonic GHP systems provide fast and efficient cooling and heating, and further increase the heat supply to the room by recovering heat from the engine coolant, which is transferred to the refrigerant via a high-efficiency plate heat exchanger. Furthermore, by using waste heat from the engine, Panasonic gas heat pumps do not require defrosting, so they can continuously deliver 100% heating capacity, even at outside temperatures as low as -20°C. In cooling mode, the heat released by the engine can be used to heat domestic hot water – the system can provide up to 30 kW of power to heat water to 65°C over the entire outdoor temperature range in both heating and cooling mode.

No defrosting required

If the system is in heating mode, at outside temperatures below 7°C the external fans turn off, further reducing energy consumption and CO2 emissions

The lowest nitrogen oxide emissions

GHP VRF systems have the lowest NOx emissions: 66% below average. Panasonic's pioneering GHP systems use a completely new lean burn combustion principle with feedback control that reduces NOx emissions to the lowest ever.

High parameters

Thanks to the advanced design of the heat exchangers, the new GHP system provides higher efficiency and lower operating costs, which, together with improved engine control, significantly increase its coefficient of performance (COP).

Use of chilled water

GHP systems are also available with a chilled water option that can be connected to single outdoor units or incorporated into a direct expansion indoor unit system. The system can be controlled via a BMS or Panasonic control panel. The chilled water temperature can be set between -15 and 15°C, and the domestic hot water temperature between 25 and 55°C.

Comparison of Gas Heat Pump to VRF system

Heating performance comparison - stable performance even at outdoor temperature = - 30 oC

Unlike electric VRF systems, Gas Heat Pumps use not only the heat received from the environment through evaporation of the refrigerant, but also the waste heat from the combustion engine, so they are able to provide full heating power even at -20 oC and stable and efficient heating power at -30 oC. By utilising the additional heat from the combustion engine, our Gas Heat Pumps can provide an efficient and low-cost source of heat even during the harshest of frosts.

Comparison of room temperature stabilisation

The Gas Heat Pumps sold and serviced by ART-KLIMA are particularly well suited to providing fast and efficient heating for a building. By utilising waste heat from the combustion engine, Gas Heat Pumps quickly achieve a high heating output. In addition, the waste heat from the combustion engine is used to defrost the unit, thus avoiding any downtime in the supply of heat to the heated rooms . The gas heat pumps offered by ART-KLIMA can provide an efficient and inexpensive source of heat even during the greatest frosts.

Comparison of heating start-up times

The Gas Heat Pumps sold and serviced by ART-KLIMA are particularly well suited to provide fast and efficient heating of a building. By utilising waste heat from the combustion engine, Gas Heat Pumps achieve high heating output very quickly (up to 10 x faster compared to electrically powered VRF systems) . The Gas Heat Pumps offered by ART-KLIMA can provide an efficient and low-cost source of heat even during the greatest frosts.

This is of particular importance in buildings with a large volume that are heated periodically.

Where can we use a GHP heat pump ?

1. buildings with limited access to electricity supply

The electricity consumption of ECO G (GHP) units is only 9% compared to ECOi (VRF) units, as the compressor drive uses a gas engine.

2. high DHW demand throughout the year

Using the heat from the flue gases during heating and cooling allows efficient production of DHW all year round

3. one common and flexible system for heating, cooling and c. w. u.

The ECO G system has been designed for the possibility of connecting different indoor units and controllers. In the new GE3 series,
in response to the needs of commercial customers, a refrigerant pump-out function has also been introduced.

It is possible to build a large system managed from one central controller based on GHP gas heat pumps electric VRF heat pumps and VRF-GHP gas and electric hybrid heat pumps. In this way, we can build a very extensive system tailored perfectly to the needs of the site, additionally using the entire spectrum of indoor units in both direct evaporation and water-based systems.

4. Radical reduction of CO2, NOx, SOx

GHP gas heat pumps are designed to significantly reduce emissions of carbon dioxide, nitrogen oxides and sulphur oxides into the environment, which have a very significant impact on our environment. Compared to traditional air conditioning and heating systems, gas heat pumps emit up to several times fewer pollutants into the environment.
