Product Description

Product Description

AIR-SOURCE GAS ENGINE HEAT PUMP (GEHP)
FOR HEATING AND COOLING
 

PRODUCT OVERVIEW

Air-source gas engine heat pump (GEHP) is a high-efficiency heating and cooling air conditioning system powered by natural gas. Unlike traditional electric heat pumps, GEHP uses a gas engine instead of an electric motor to drive the compressor, achieving summer cooling and winter heating through the vapor compression heat pump cycle. The indoor unit operates in the same way as a conventional air conditioner, with no gas combustion indoors, ensuring safety and reliability.

During operation, the system uses natural gas as fuel to drive the gas engine, which in turn drives the compressor to form a heat pump cycle, realizing cooling or heating. At the same time, the system recovers engine waste heat and flue gas waste heat through heat exchangers, producing hot water and storing it in a water tank, achieving cascade energy utilization and low-temperature flue gas emission.

Since natural gas is used as the main energy source, the annual electricity consumption of GEHP is only 6% of that of electric heat pump units. When used on a large scale, there is no need for power capacity expansion, which significantly reduces construction costs, labor costs, and operating expenses. It is an ideal choice to replace electric heat pumps and achieve energy saving and consumption reduction.

APPLICATION FIELDS

Air-source gas engine heat pumps (GEHP) can be used in scenarios such as hotels, commercial apartments, bathing centers, fitness centers, hospitals, nursing homes, gate station applications, factory dormitories, high-temperature drying, and feed processing. They provide heating and cooling supply, domestic hot water, and emergency power generation, significantly reducing electricity consumption and operating costs.

PRODUCT FEATURES

 

Remote Control, Intelligent Management
Supports one-key power on/off and mode switching. Adopts IoT technology for real-time remote monitoring of equipment operation status, making management more convenient and efficient.

Multiple Operating Modes, Flexible Adaptation
Provides single cooling mode, cooling + hot water mode, and heating mode. Can be flexibly switched according to different working conditions and requirements to meet diverse application scenarios.

Multi-Unit Parallel Connection, Group Control Operation
A single host supports group control mode and can operate up to 10 units in parallel, suitable for large-load commercial and industrial sites.

Intelligent Frost-Free Technology, Stable
Heating at Low Temperatures
Utilizes engine waste heat for intelligent defrosting - more defrosting when there is more frost, no defrosting when there is no frost - ensuring stable and reliable heating under low-temperature conditions.

High Efficiency and Energy Saving, Free
Hot Water Production
Free domestic hot water can be produced while cooling in summer. Primary energy ratio (PER) reaches up to 167%, significantly improving energy utilization efficiency.

Silent Design, Low-Noise Operation
Adopts professional vibration damping design and sheet metal noise reduction treatment. Operating noise is as low as 63 dB, without disturbing commercial or industrial environments.
