Waste‑Heat‑Driven Vapour Absorption Chiller

BROAD's Waste‑Heat‑Driven Vapour Absorption Chiller converts low‑grade thermal energy into high-quality chilled water (above 5 °C) and heating water (below 95 °C) with capacity ranges from 233 kW to 11,630 kW (66–3,307 RT), enabling large-scale HVAC and process cooling applications. Designed for thermal integration with industrial waste heat systems such as hot exhaust gases, boiler flue gases, or process steam, the chiller achieves outstanding Coefficient of Performance (COP) by utilizing heat that would otherwise be wasted, driving both energy savings and carbon reduction.

Equipped with robust lithium bromide-water absorption technology and tailor-engineered shell-and-tube heat exchangers, the unit ensures durable performance under variable load conditions. Waste heat input ranges are flexible, accommodating exhaust fluid temperatures from 150 °C upwards, with effective condenser control and vacuum maintenance for optimal efficiency. Central to the design are automatic non-condensable gas purge systems, crystallisation prevention circuits, and smart controllers that continuously adjust operation to maintain high COP and protect long-term integrity.

Ideal for integration with CHP plants, industrial boilers, and flue‑gas stacks, this waste‑heat-driven chiller supports both chilled water and hot water outputs making it perfect for combined cooling, heating, and domestic hot water (CCHP) systems or energy-positive building envelopes. Its modular configuration, low mechanical complexity, and minimal electric power requirement—only for pumps and controls—ensure it operates reliably in industrial parks, campuses, hospitals, and hotels, especially where grid electricity is costly or limited.
