Further, the rise in popularity in the industrial sector, particularly the petrochemical industry, and the growing use of absorption chillers in solar cooling projects are projected to fuel market growth throughout the course of the projection period. Furthermore, rigorous government regulations for the use of absorption chillers is another important driver fuelling the market expansion because they are more environmentally friendly than traditional vapour compressors due to decreased emissions of pollutants and harmful gases.
The Asia Pacific region and other developing countries have triggered the rising demand for absorption chillers, which will continue to uplift the market. Due to electrical shortages caused by inadequate electricity flow in these developing countries, the application of the product is anticipated to increase. As a result of its affordability compared to more conventional alternatives, the product is in high demand among consumers.
