Hope Deepblue Technology Innovation - Low Temp. Absorption Chiller
Hope Deepblue's breakthrough in ultra-low temperature LiBr absorption chiller technology addresses the challenge of the -5℃ to 0℃ cooling load demand in industries like food, beverage, and refrigeration. Traditionally, such cooling demands have been met using electric chillers, which are power-intensive and costly. These industries, however, often rely on waste heat from sources like flue gas, hot water, and steam, but existing technologies struggled to efficiently integrate these energy sources, especially for low-temperature applications.
The core innovation of Hope Deepblue’s technology lies in its ability to overcome the “freezing point exclusion zone,” a temperature range where conventional LiBr absorption chillers using water as a refrigerant cannot function. Water, while safe and environmentally friendly, freezes at 0℃, making it unsuitable for cooling below this point. The ultra-low temperature LiBr absorption chiller developed by Hope Deepblue has effectively addressed this limitation, making it possible to achieve cooling in the -5℃ to 0℃ range using waste heat.
This innovation not only provides an energy-efficient alternative to electric chillers but also enhances overall energy efficiency for enterprises by utilizing available waste heat. This breakthrough is a significant step forward in reducing energy costs, lowering carbon footprints, and improving sustainability across industries that require low-temperature cooling. It's a testament to Hope Deepblue's commitment to technological advancement and sustainable energy solutions.
The ultra-low temperature LiBr absorption chiller developed by Hope Deepblue is a major technological advancement that has successfully overcome the barrier of refrigerant water freezing, a challenge that has long limited the effectiveness of LiBr absorption chillers in low-temperature applications. The Hope Deepblue research team achieved this by conducting extensive studies on the physical properties of LiBr solutions and water, coupled with in-depth analysis of the technological processes involved in LiBr absorption units. Through repeated tests, optimizations, and fine-tuning, they were able to identify the key factors for precisely controlling the freezing temperature of refrigerant water, enabling the chiller to produce frozen water at temperatures as low as -5℃.
This achievement places Hope Deepblue's ultra-low temperature LiBr absorption chiller at the forefront of both domestic and global industries, with the unit receiving authoritative testing and certification. It has already been successfully applied and verified in a range of industries, including food, brewing, pharmaceuticals, and specialized chemicals, both domestically and internationally.
One of the standout features of this technology is its reliance on thermal energy, which significantly reduces power consumption—by more than 97%—compared to traditional electric chillers. This reduction in power dependency not only lowers operational costs but also improves energy security, optimizing the overall energy structure. The unit has emerged as an excellent solution for energy saving and carbon reduction, making it a top choice for industries seeking more sustainable and efficient cooling technologies.
By addressing a critical energy challenge and offering a reliable, energy-efficient alternative, Hope Deepblue’s ultra-low temperature LiBr absorption chiller positions itself as a game-changer in the field of industrial cooling, contributing to both economic and environmental sustainability.
Hope Deepblue's high-efficiency non-electric centralized cooling, energy reservation, and carbon reduction technology has been recognized as a key innovation and selected for special recommendation at the major scientific innovation projects venue of the Science and Technology Innovation Fair. This recognition highlights Hope Deepblue’s commitment to advancing sustainable and energy-efficient technologies.
One of the company’s most exciting areas of innovation is in the use of solar energy, an abundant and clean resource that has traditionally been harnessed for power generation and low-temperature heating. However, Hope Deepblue is taking this a step further by focusing on the development of efficient solar-powered cooling and heating systems. This work seeks to overcome the limitations of current solar energy applications by enabling the direct use of solar energy for both cooling and heating, a combination that could revolutionize energy systems, particularly in industries with high cooling demands.
Through its research and development efforts, Hope Deepblue is striving to perfect solar cooling and heating integration, making it a viable, energy-efficient, and environmentally-friendly alternative to traditional energy-consuming systems. This technology would significantly reduce energy consumption, lower carbon emissions, and offer a more sustainable approach to both cooling and heating needs.
By focusing on both energy reservation and carbon reduction, Hope Deepblue’s work in this area is poised to lead the way in developing a future-proof, green energy solution that aligns with global sustainability goals. With solar energy as its cornerstone, the company’s technology has the potential to significantly transform the landscape of industrial cooling and heating, offering an innovative approach to energy management and environmental stewardship.
Hope Deepblue’s solar-powered absorption air conditioning system is an innovative and efficient solution that addresses both cooling needs and energy sustainability. This system is composed of a solar heat collection system and an absorption solar air conditioning unit. Unlike traditional photovoltaic-based systems, this technology directly uses solar energy for driving the cooling process, without relying on complex photovoltaic components.
The system utilizes a trough-type collector for photothermal conversion, with heat conduction oil serving as the heat transfer medium. The high-temperature heat conduction oil drives the absorption refrigeration system, enabling direct solar-driven refrigeration. This innovative method eliminates the need for electricity, significantly reducing energy consumption and carbon emissions.
In addition, the system is integrated with an energy storage and multi-energy coupling system, enabling the complementary utilization of solar energy alongside other energy sources such as natural gas, oil, and waste heat from various processes. This multi-energy coupling not only addresses the challenges of solar energy's diurnal and seasonal fluctuations but also enhances the system's flexibility and efficiency by using available energy from multiple sources.
Hope Deepblue’s technology has already been applied successfully in a range of settings, including universities, exhibition halls, government office buildings, and other user units. According to statistics, China's existing public building area is about 30 billion square meters. If just 1% of this area were to adopt this solar cooling and heating technology, it could save approximately 3.59 million tons of standard coal and reduce about 9.5 million tons of carbon dioxide annually. This represents a significant contribution to China’s sustainability goals, particularly the realization of "Carbon Peak and Neutrality."
By offering a practical solution for reducing energy consumption and lowering carbon emissions, this system not only advances the use of renewable energy but also supports global efforts to combat climate change. The integration of solar energy with waste heat and other resources positions this technology as a key player in the transition toward greener, more efficient energy systems.
