Direct Fired Absorption Heat Pump
Efficient Waste Heat Recovery for Sustainable Industrial Heating

Product Overview
The direct fired absorption heat pump is a high-efficiency heating solution driven by clean fuels such as natural gas or liquefied petroleum gas. Utilizing lithium bromide aqueous solution as the working fluid, this system effectively recovers and upgrades low-grade waste heat for use in process heating and district heating. It is widely applicable in industries such as power generation, petrochemicals, steel, and chemical processing.

Advantages

• High Energy Utilization: Double-effect operation design enables simultaneous recovery of waste heat and fuel energy
• Environmentally Friendly: Fluorine-free working fluid with no harmful emissions, supporting carbon reduction goals
• Intelligent Control: Features such as one-button start/stop, remote monitoring, load regulation, and solution concentration control
• Versatile Adaptability: Compatible with various heat sources including waste hot water, low-pressure steam, and natural water sources
• Stable and Reliable: Proven structural design ensures long-term, low-maintenance operation under continuous working conditions

Working Principle 
At startup, refrigerant water in the evaporator evaporates, absorbing heat from the chilled water system and reducing its temperature—achieving waste heat recovery. The resulting refrigerant vapor is absorbed by concentrated lithium bromide solution in the absorber, releasing heat to produce hot water. The diluted solution is preheated in the heat exchanger and sent to the generator, where it is reheated by direct combustion of natural gas to regenerate refrigerant vapor. This vapor condenses in the condenser, further heating the hot water. The concentrated solution then returns to the absorber, completing the cycle.

Applications

• Waste heat recovery in thermal power plants
• Process heating in oil drilling and chemical plants
• Utilization of residual heat in steel production
• Urban district heating systems
• Industrial parks requiring both heating and cooling
