Solar-link Waste Heat Driven Absorption

The Gene-Link absorption chiller is a waste heat-driven chiller driven by steam or natural gas and supplemental hot water from cogeneration systems or solar heat panels. It can lead to significant energy savings and cost reductions, as well as a reduced environmental impact, and can be used in wide applications where reliable, large-scale cooling is needed, such as commercial buildings, industrial processes, and data centers.

Gas-fired absorption chiller Gene-Link (EXJE series)

The input of waste hot water can reduce gas consumption by approximately 40% during rated cooling operations. Additionally, the chiller can be operated with waste hot water only under low load conditions (approximately 58% or lower), and during partial load operations, priority is given to the use of waste hot water, significantly reducing gas consumption. Furthermore, in addition to the waste hot water from cogeneration systems, the Gene-link absorption chiller can also utilize solar heat as another potential waste heat source.

On the other hand, by installing a plate heat exchanger on the Gene-Link side for heating operation, waste heat can be utilized, eliminating the need for a heat exchanger on the facility side and simplifying the system. This can result in a gas consumption reduction rate of 55% to 69% for heating(optional).

Steam-fired Absorption chiller with cogeneration systems

This unit increases the amount of waste hot water recovered from cogeneration systems compared to conventional models while reducing the amount of steam consumed by 30%. Additionally, the chiller can operate with waste hot water alone under low load conditions (approximately 50% or lower). In addition to utilizing the waste hot water from cogeneration systems, solar heat can also be used as an energy source.

Hot-water steam absorption chiller

The Hot Water/Steam Gene-Link is an absorption chiller with a waste steam regenerator added. The Gene-Link absorption chiller can utilize the wasted steam, which has a higher temperature than hot water, making the waste heat conversion into cooling more efficient and resulting in higher energy efficiency. Another advantage is that a large amount of waste heat can be recovered by a single chiller unit, allowing for the introduction of engine generators with larger power-generating capacities. By giving priority to the use of waste hot water and waste steam, the amount of gas consumed can be reduced. Furthermore, at loads below 68%, the chiller can be operated using only wasted heat.
