Description
FIELD OF INVENTION
[0001] The present invention relates to the field of thermal management systems and cooling technologies. More specifically, it pertains to a hybrid cooling system that combines a compressor-based cooling mechanism with an adsorption chiller to optimize energy efficiency and provide enhanced cooling performance by utilizing waste heat for secondary cooling. This invention finds applications in residential, commercial, and industrial cooling systems, offering a sustainable and cost-effective solution for thermal management.BACKGROUND
[0002] Efficient thermal management systems play a vital role in modern society, encompassing a wide range of applications such as residential cooling, commercial air conditioning, and industrial process management. Traditional cooling systems predominantly rely on vapor compression technologies, which operate by compressing and expanding refrigerants to achieve cooling effects. While effective, these systems are known for their substantial energy consumption, contributing to high operational costs and significant environmental impacts due to greenhouse gas emissions.
[0003] As global energy demands continue to rise, there is an urgent need for more energy-efficient and sustainable cooling solutions. Alternative cooling technologies, such as adsorption and absorption cooling, have been developed to address these challenges. Adsorption cooling, in particular, has gained attention as a potential solution for reducing electricity dependency by utilizing low-grade thermal energy sources, such as waste heat from industrial processes or renewable energy sources like solar thermal systems. Unlike conventional refrigeration cycles that require mechanical work, adsorption chillers operate based on the adsorption-desorption cycles of a working pair, such as silica gel and water. In this process, the adsorbent material captures water vapor, which results in a cooling effect, while waste heat is used to regenerate the adsorbent during the desorption phase.
[0004] Despite its potential benefits, adsorption cooling technology has several limitations. One of the significant challenges is its intermittent operation due to the cyclic nature of the adsorption and desorption processes. Since a single adsorption bed requires time to undergo regeneration before it can resume cooling, standalone adsorption chillers often experience fluctuations in cooling output, making them less reliable for applications requiring continuous cooling. Additionally, adsorption chillers typically have a lower cooling capacity and coefficient of performance (COP) compared to conventional vapor compression systems, which limits their widespread adoption.
[0005] Another critical issue in conventional cooling systems is the inefficient utilization of waste heat. Many industrial and commercial facilities generate significant amounts of waste heat during operations, often dissipating into the environment without being effectively harnessed. While some cooling systems have attempted to incorporate waste heat recovery mechanisms, their integration with existing cooling infrastructures remains a complex challenge due to design constraints, thermal losses, and the need for precise control over heat exchange processes.
[0006] Furthermore, thermal management systems require advanced control mechanisms to adapt to varying cooling demands efficiently. Traditional cooling systems often operate at fixed loads or rely on simple on / off controls, leading to energy inefficiencies, frequent cycling of the compressor, and increased wear and tear on components. Achieving an optimal balance between cooling demand, waste heat utilization, and system efficiency requires a sophisticated control strategy capable of dynamically adjusting system parameters in real-time.
[0007] Due to these challenges, there remains a need for an advanced cooling system that can integrate multiple cooling technologies to optimize performance, improve energy utilization, and provide continuous cooling output without relying solely on conventional vapor compression methods. The development of such a system would require innovations in heat exchange mechanisms, adsorption chiller design, dynamic load distribution, and intelligent control systems to enhance thermal management solutions' overall reliability and effectiveness.SUMMARY
[0008] Embodiments disclosed include a hybrid cooling system comprising compressor-based cooling and adsorption chiller technology to deliver a highly energy-efficient and environmentally sustainable thermal management solution. Disclosed embodiments address the limitations of traditional cooling methods by leveraging waste heat recovery and advanced control mechanisms to enhance overall efficiency and performance.

According to an embodiment, the hybrid cooling system comprises a plate-type heat exchanger, incorporated to capture the waste heat from the condenser and transfer it to the adsorption chiller. Utilizing this waste heat, the adsorption chiller operates secondary cooling through adsorption and desorption cycles using an environmentally friendly silica gel-water working pair. This dual cooling mechanism reduces the system's energy demands and maximizes the utilization of available thermal energy.
[0010] A preferred embodiment of the system features two evaporators, each dedicated to its respective cooling mechanism. The first evaporator, connected to the compressor, delivers primary cooling, while the second evaporator, connected to the adsorption chiller, provides secondary cooling. The hybrid design ensures the system can dynamically adapt to varying thermal loads, offering reliable and continuous cooling performance.
[0011] The hybrid cooling system incorporates a sophisticated control system equipped with temperature and pressure sensors to enhance operational efficiency further. This control system continuously monitors the thermal demands in real-time and dynamically distributes the cooling load between the two evaporators. Additionally, a proportional-integral-derivative (PID) controller is employed to fine-tune the operations of the compressor and adsorption chiller, ensuring optimal performance under varying conditions.
[0012] A significant feature of the invention is its ability to store excess cooling capacity in an optional thermal storage unit. This unit is operatively connected to the adsorption chiller's evaporator and can store surplus cooling energy for future use during peak demand periods. This functionality improves the system's resilience and enhances its ability to maintain consistent performance during fluctuating load requirements.
[0013] Moreover, the adsorption chiller in the system is designed with multiple adsorption beds operating out of phase, ensuring a continuous and stable cooling output. This design addresses one of the primary challenges of standalone adsorption chillers, which often struggle with intermittent cooling due to the cyclic nature of adsorption and desorption processes.
[0014] The hybrid cooling system balances energy efficiency, environmental sustainability, and cost-effectiveness by integrating waste heat recovery, dynamic load distribution, and advanced real-time monitoring. The invention is particularly suited for residential, commercial, and industrial applications where efficient thermal management is critical. It represents a significant advancement in cooling technology, offering a robust and adaptable solution to meet the growing demand for energy-efficient cooling systems.BRIEF DESCRIPTION OF DRAWINGS

Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art. The system, methods, and examples provided herein are illustrative only and are not intended to be limiting.
[0024] The present embodiment will now be described in greater detail with reference to the accompanying drawings, which illustrate exemplary embodiments of the hybrid cooling system. These drawings are provided for illustrative purposes and should not be interpreted as limiting the scope of the invention.
[0025] FIG. 1 illustrates a block diagram of the cooling system (100), depicting the interaction and functional relationship between its key components. The system integrates a compressor-based primary cooling cycle with an adsorption chiller-based secondary cooling cycle, optimizing energy efficiency by utilizing waste heat from the compressor for additional cooling and dynamic cooling load distribution.
[0026] The illustrated embodiment comprises a compressor (104), which serves as the primary cooling mechanism, compressing a refrigerant to increase its pressure and temperature. The compressed refrigerant is circulated through the condenser (106), where heat generated during the compression process is rejected. This rejected beat is typically lost in conventional systems, but in the disclosed embodiment, it is efficiently captured and transferred by a heat exchanger (108) to the adsorption chiller (110). The heat exchanger (108) is thermally coupled to the condenser, designed to capture and transfer the rejected heat to the adsorption chiller (110). This component is crucial for energy recovery, ensuring that waste heat drives an adsorption-desorption cycle, which facilitates secondary cooling without additional electrical input. The adsorption chiller (110) operates using a solid adsorbent material (112), such as silica gel or zeolite, which adsorbs and desorbs a refrigerant (e.g., water or ammonia) to generate secondary cooling. The system features two evaporators to manage cooling distribution effectively:
[0027] The first evaporator (102) delivers primary cooling to the target environment or load (120). The second evaporator (116) is linked to the adsorption chiller (110) through a cooling circuit (114) and provides secondary cooling either directly to the load / room (120) or to an optional thermal storage unit. This storage unit can retain excess cooling capacity for use during peak demand periods, reducing reliance on the compressor. To enhance operational efficiency and adaptability, the system may include an optional renewable energy integration unit. This unit comprises solar thermal collectors, photovoltaic panels, or geothermal heat pumps, supplying supplemental heat to the adsorption chiller when necessary, ensuring its operation remains sustainable and energy-efficient.
[0028] A control system (118) dynamically regulates cooling load distribution between the primary and secondary evaporators based on real-time temperature, pressure, and demand conditions. It employs predictive algorithms and machine learning models to adjust system operation for optimal energy efficiency. The cooling circuit (114) ensures smooth interaction between all cooling components, while maintaining stable cooling output to the target load or room (120). FIG. 1 provides a comprehensive structural overview of the hybrid cooling system, demonstrating the integration of compressor-based and adsorption-based cooling mechanisms. By leveraging waste heat recovery, intelligent load balancing, and renewable energy integration, the system minimizes energy consumption while maintaining high-performance cooling output.
[0029] FIG. 2 depicts a system simulation showing the general load distribution between the primary and secondary cooling mechanisms. The simulation highlights how the system dynamically adjusts the cooling load based on thermal demands, optimizing energy usage. The interaction between the compressor and adsorption chiller is shown, emphasizing the system's ability to balance primary and secondary cooling under typical conditions.
[0030] FIG. 3 provides a system simulation graph focused on a 2-ton cooling load scenario. It demonstrates the system's performance under specific operating conditions, with detailed insights into the compressor and adsorption chiller's load distribution and cooling contributions. This figure showcases the system's adaptability and efficiency in managing higher cooling loads.
[0031] FIG. 4 provides a step-by-step breakdown of the operational sequence of the cooling method This vertical flowchart visually represents how the system processes thermal energy, from detecting cooling demand to delivering efficient cooling through the integration of primary and secondary cooling mechanisms.
[0032] According to the illustrated embodiment, the control system detects a cooling demand (402) in the target space. Sensors continuously monitor temperature and pressure levels, triggering the system to initiate cooling operations when predefined thresholds are met. Once cooling demand is identified, the compressor activates to provide primary cooling. The compressor compresses (404) a refrigerant, raising its pressure and temperature before circulating it through the system.
[0033] Step 406, Heat Rejection in Condenser; as a by-product of compression, the refrigerant releases heat when it reaches the condenser. In conventional systems, this waste heat is dissipated into the environment, resulting in energy loss. However, in this hybrid cooling system, the heat is efficiently captured and repurposed. Instead of discarding the waste heat, the system utilizes a heat exchanger to transfer this energy (408) to the adsorption chiller. The heat exchanger enhances thermal efficiency by ensuring effective heat transfer between the condenser and the adsorption system.
[0034] The adsorption chiller receives the waste heat and utilizes (410) it by initiating its adsorption-desorption cycle. The solid adsorbent material (such as silica gel or zeolite) adsorbs the refrigerant vapor, creating a cooling effect, During the desorption phase, the captured heat regenerates the adsorbent material, allowing the process to repeat. This mechanism enables secondary cooling with minimal additional energy input.
[0035] In step 412, cooling by compressor→condensor→evaporator and Adsorption Evaporators illustrated as the cooling effect is delivered through two evaporators; The primary evaporator (associated with the compressor) provides direct cooling using the vapor compression cycle. The secondary evaporator (associated with the adsorption chiller) supplies additional cooling using waste heat-driven adsorption cooling.
[0036] The control system dynamically distributes the cooling load (414) between the primary and secondary evaporators based on real-time thermal demand. Predictive algorithms analyze historical and current system data to optimize energy efficiency and maintain a stable cooling output. If the cooling demand is low, the system prioritizes the adsorption chiller to reduce compressor workload, thereby saving energy. During peak demand periods, both cooling mechanisms work simultaneously to ensure adequate cooling. The final step in the process is the delivery of cooled air (416) to the target space / room. The control system continuously monitors system performance and adjusts load distribution to maintain optimal cooling conditions.
[0037] FIG. 5 presents an enhanced flowchart of the hybrid cooling method, detailing the complete operational sequence and interactions between the primary cooling cycle (compressor-based) and the secondary cooling cycle (adsorption chiller-based). This figure expands upon FIG. 4 by incorporating additional details on thermal energy transfer, cooling load distribution, and predictive control mechanisms to optimize efficiency,
[0038] According to an embodiment, the method comprises compressing a refrigerant for primary cooling 502 to increase its pressure and temperature. This initiates the primary cooling cycle, forming the foundation of the system's cooling capabilities. The high-temperature refrigerant moves to the condenser, where it rejects heat generated during compression 504. This waste heat, which would typically be lost in conventional cooling systems, is captured for reuse in the adsorption chiller. The heat exchanger plays a critical role in repurposing waste heat by transferring it from the condenser to the adsorption chiller 506. This step optimizes energy efficiency by ensuring that thermal energy is not wasted but instead used to drive a secondary cooling process. The adsorption chiller captures the transferred beat 508 and utilizes it to drive adsorption-desorption cycles. A solid adsorbent material (such as silica gel, zeolite, or a metal-organic framework) absorbs the refrigerant vapor, generating a cooling effect. The heat from the condenser is then used to regenerate the adsorbent, allowing continuous operation. In step 510, the adsorption chiller generates secondary cooling through adsorption-desorption cycles. Since this process is driven by waste heat, it requires little to no additional electricity, making it a highly energy-efficient cooling mechanism.
[0039] In step 512 the first evaporator delivers primary cooling directly to the load. This evaporator functions as the main cooling source in high-demand scenarios and operates using the vapor compression cycle. Similarly in step 514 the second evaporator, associated with the adsorption chiller, provides secondary cooling to either the cooling load or an optional thermal storage unit. The stored cooling energy can be utilized during peak demand periods, reducing reliance on the compressor. The control system manages the distribution of the cooling load between the primary and secondary evaporators based on real-time thermal demand. Predictive algorithms and machine learning models analyze historical usage patterns and adjust operations accordingly explained in step 516. This dynamic approach minimizes energy consumption and enhances system reliability. FIG. 5 offers a detailed visualization of the hybrid cooling system's energy flow and operational sequence. By integrating waste heat utilization, intelligent load balancing, and predictive control mechanisms, the system optimizes efficiency and sustainability. This enhanced flowchart highlights the seamless coordination between the primary and secondary cooling cycles, ensuring continuous, energy-efficient cooling performance.
[0040] Embodiments disclosed include a hybrid cooling system that integrates a vapor compression cooling mechanism with an adsorption chiller to achieve superior energy efficiency, environmental sustainability, and dynamic adaptability to varying thermal demands. The following description comprehensively explains the system's components, operation, and key features.1. Compressor
[0041] According to an embodiment, the compressor is a core component of the hybrid cooling system, serving as the primary mechanism for generating cooling. It operates on the principles of vapor compression, compressing a refrigerant to increase its pressure and temperature. This process enables the refrigerant to absorb and dissipate heat efficiently, forming the foundation of the primary cooling cycle. The compressor in the hybrid cooling system is designed to operate at variable speeds, allowing it to modulate its output based on real-time cooling demands. This feature significantly enhances energy efficiency by ensuring that the compressor only consumes the energy required to meet the current load, thereby reducing unnecessary power consumption during low-demand periods.
[0042] In the disclosed embodiments, during the compression process, the refrigerant generates heat, which is rejected by the system's condenser. Instead of being lost to the environment, this waste heat—a valuable by-product—is transferred to the adsorption chiller via a heat exchanger. This enables secondary cooling and enhances overall system efficiency.
[0043] Further, the compressor is integrated into the system's advanced control mechanism, continuously monitoring parameters such as temperature and pressure. This integration allows the control system to adjust the compressor's operation dynamically, ensuring optimal performance under varying thermal conditions. The compressor is engineered for high durability and is capable of withstanding prolonged operational cycles while maintaining consistent performance. Its robust design ensures reliable cooling, even in demanding applications.
[0044] According to an embodiment, the compressor not only provides direct cooling to the load through the primary evaporator but also plays a pivotal role in powering the secondary cooling mechanism. By supplying waste heat to the adsorption chiller, the compressor allows the system to operate in a hybrid mode that balances energy efficiency and performance. The use of a variable-speed compressor makes the hybrid cooling system adaptable to a wide range of applications, including residential air conditioning, commercial cooling systems, and industrial processes. Its ability to modulate output and integrate with the adsorption chiller ensures it meets the demands of modern, energy-conscious environments.2. Condenser
[0045] According to one embodiment, the condenser is a vital component of the hybrid cooling system, primarily responsible for rejecting heat generated during the refrigerant compression cycle. It plays a dual role: ensuring the efficient operation of the primary cooling cycle and serving as a heat source for the adsorption chiller, which provides secondary cooling.
[0046] The disclosed embodiments include a condenser that receives high-pressure, high-temperature refrigerant from the compressor. It facilitates the dissipation of this heat into the surrounding environment or a secondary heat transfer medium, causing the refrigerant to cool and condense into a liquid state. This step is critical for maintaining the efficiency and continuity of the vapor compression cycle. Unlike conventional systems, where waste heat from the condenser is discarded, the hybrid cooling system incorporates a heat exchanger connected to the condenser. This setup captures the rejected heat and transfers it to the adsorption chiller. By utilizing this waste heat, the system achieves higher overall energy efficiency and sustainability.
[0047] According to one embodiment, the condenser is designed to maximize heat transfer efficiency. This is achieved through advanced surface technologies, optimized fin arrangements, and material selections that enhance thermal conductivity. These optimizations reduce the system's energy consumption and improve performance under various operating conditions. Temperature and pressure sensors within the control system continuously monitor the condenser's performance, ensuring that the heat rejection process remains optimal. Additionally, the system can dynamically adapt to changes in operating conditions or thermal loads.
[0048] In addition to its primary function of enabling the vapor compression cycle, the condenser's role in providing waste heat to the adsorption chiller is central to the hybrid cooling system. This dual functionality allows the system to combine primary and secondary cooling mechanisms seamlessly, improving energy utilization and reducing environmental impact. The condenser is adaptable to various cooling applications, including residential, commercial, and industrial settings. Its integration with both the primary compressor cycle and the secondary adsorption chiller ensures the hybrid cooling system meets diverse thermal management needs with enhanced efficiency.3. Heat Exchanger
[0049] Embodiments disclosed comprise a heat exchanger, designed to efficiently transfer heat from the condenser to the adsorption chiller. By recovering waste heat generated during the refrigerant compression process, the heat exchanger enables the system to operate the secondary cooling cycle, significantly enhancing overall energy efficiency. The heat exchanger can be of different configurations, including plate-type, shell-and-tube, or microchannel designs, to ensure efficient thermal conductivity and adaptability across various operational conditions.
[0050] The heat exchanger connects the condenser to the adsorption chiller, facilitating the transfer of waste heat. In the hybrid cooling system, a plate-type heat exchanger is typically used due to its high thermal conductivity and compact design. This ensures minimal heat loss during the transfer process and maximizes the system's efficiency. The heat exchanger's plate-type configuration offers a large surface area for heat transfer while maintaining a small footprint. This design is particularly suited for hybrid systems, where space efficiency and performance are critical. According to an embodiment, the heat exchanger is configured to capture heat rejected by the condenser and repurpose it to drive the adsorption chiller. This Ensures that the heat supplied to the adsorption chiller is at an optimal level, enabling consistent adsorption-desorption cycles.
[0051] According to an embodiment, the heat exchanger operates in conjunction with the control system, which monitors temperature and pressure conditions to regulate heat transfer rates. This integration ensures that the adsorption chiller receives a consistent and adequate heat supply, maintaining its efficiency and cooling output.
[0052] Additionally and alternatively, the heat exchanger acts as the bridge between the primary and secondary cooling cycles. Capturing and repurposing waste heat minimizes energy wastage and enables the hybrid system to achieve superior energy efficiency. This design also supports the system's dynamic load sharing by ensuring that the adsorption chiller can operate effectively during varying thermal loads. It reduces the reliance on external energy sources by utilizing waste heat. The compact design fits seamlessly into the hybrid system without adding significant bulk and improves sustainability by reducing heat loss and supporting environmentally friendly cooling processes.4. Adsorption Chiller
[0053] Embodiments disclosed comprise an adsorption chiller as a major component of the hybrid cooling system, responsible for providing secondary cooling by utilizing waste heat from the primary cooling cycle. Unlike conventional vapor compression systems, which rely on mechanical energy, the adsorption chiller operates using a thermally driven process, making it an energy-efficient and environmentally friendly alternative. This mechanism significantly reduces electricity consumption and optimizes thermal energy utilization by repurposing heat that would otherwise be lost.
[0054] At the core of the adsorption chiller is the adsorption-desorption cycle, which relies on a solid adsorbent material, such as silica gel, zeolite, or metal-organic frameworks (MOFs), and a refrigerant, typically water, ethanol, or ammonia. The system operates under vacuum conditions, which enhances the efficiency of the adsorption and desorption phases. During the adsorption phase, the solid adsorbent captures the refrigerant vapor, causing the refrigerant to condense and produce a cooling effect. As the refrigerant condenses, it absorbs heat from the cooling load, thereby lowering the temperature of the environment. Once the adsorbent reaches its saturation limit, the desorption phase begins.
[0055] According to an embodiment, during desorption, the heat exchanger transfers waste heat from the condenser to the adsorption chiller, which increases the temperature of the adsorbent material. This heat input drives off the adsorbed refrigerant, converting it back into vapor, which is then condensed and recirculated in the cooling cycle. The desorption phase regenerates the adsorbent material, preparing it for the next cycle. The system maintains continuous cooling output by employing multiple adsorption beds that operate in an alternating manner—while one bed undergoes adsorption, the other is in the desorption phase. This staggered operation ensures a steady cooling effect, preventing the intermittent performance issues that occur in traditional single-bed adsorption chillers.
[0056] One of the significant advantages of the adsorption chiller is its ability to operate at relatively low temperatures. The regeneration temperature typically ranges between 60° C. and 150° C., making it compatible with various waste heat sources from industrial processes, power plants, and renewable energy systems. This broadens the applicability of the hybrid cooling system to environments where conventional cooling technologies may not be feasible. Additionally, the system is designed to achieve a Coefficient of Performance (COP) of at least 0.55, contributing to an overall system efficiency of COP 3.0 or higher when integrated with the primary cooling mechanism. The inclusion of a smart control system enhances the adsorption chiller's efficiency by dynamically adjusting its operation based on real-time cooling demand. Predictive algorithms analyze historical data and current load conditions, optimizing the balance between primary and secondary cooling. The system can prioritize the adsorption chiller during low-to-moderate cooling demand periods, reducing reliance on the compressor and lowering energy consumption by up to 30% compared to conventional cooling systems.
[0057] Overall, the adsorption chiller plays a vital role in achieving sustainable, cost-effective, and energy-efficient cooling. By leveraging waste heat, operating without mechanical compression, and ensuring continuous cooling output through multiple adsorption beds, the system minimizes environmental impact while maximizing cooling performance. Its adaptability across residential, commercial, and industrial applications makes it an innovative solution for modern thermal management challenges.5. Cooling Circuit
[0058] Embodiments disclosed comprise the cooling circuit in the hybrid cooling system, configured for the efficient circulation and transfer of thermal energy between the primary and secondary cooling mechanisms. It plays a critical role in ensuring optimal heat exchange, waste heat utilization, and cooling load distribution between the compressor-based primary cooling system and the adsorption chiller-based secondary cooling system. The circuit is designed to maximize energy efficiency, minimize thermal losses, and maintain continuous cooling performance under varying load conditions.
[0059] According to an embodiment, the cooling circuit comprises the compressor, which compresses a refrigerant, raising its pressure and temperature. The high-pressure refrigerant flows to the condenser, where it releases heat. Unlike conventional systems where this heat is dissipated into the environment, the hybrid cooling system integrates a heat exchanger that captures this waste heat and transfers it to the adsorption chiller. The adsorption chiller then utilizes this thermal energy to drive adsorption-desorption cycles, generating secondary cooling. The control system dynamically manages the cooling circuit by continuously monitoring system parameters such as temperature, pressure, and cooling demand. It optimizes the distribution of cooling load between the primary and secondary evaporators, ensuring efficient energy utilization. During periods of low demand, the system prioritizes the adsorption chiller, reducing reliance on the compressor and lowering electricity consumption. During peak demand, both cooling circuits work together to meet the required cooling capacity.
[0060] Additionally, the cooling circuit may incorporate a thermal storage unit, which allows excess cooling capacity generated by the adsorption chiller to be stored and utilized later during high-demand periods. This feature further enhances energy efficiency and operational flexibility.6. Evaporators
[0061] According to a preferred embodiment, the hybrid cooling system incorporates two distinct evaporators—the primary evaporator and the secondary evaporator—each playing a crucial role in delivering efficient and adaptive cooling. These components operate in tandem to meet varying thermal demands, ensuring consistent and optimized cooling performance.
[0062] The primary evaporator is directly associated with the compressor and forms an integral part of the vapor compression cycle. Refrigerant, compressed and condensed in the earlier stages, expands in the primary evaporator, absorbing heat from the surrounding environment or the cooling load. This heat absorption results in the primary cooling effect, which is dynamically regulated by the system's control mechanisms to ensure optimal performance. The primary evaporator serves as the primary source of cooling and is essential for meeting immediate cooling demands with precision and efficiency.
[0063] On the other hand, the secondary evaporator is connected to the adsorption chiller and is configured to deliver secondary cooling. Waste heat from the condenser drives the adsorption-desorption cycles in the chiller, which subsequently produces chilled air or water. This cooling output is transferred to the load via the secondary evaporator. Unlike the primary evaporator, which relies on electrical or mechanical energy, the secondary evaporator utilizes energy recovered from waste heat, making it a highly sustainable and energy-efficient component of the system.
[0064] Embodiments disclosed comprise the dual-evaporator, designed to allow dynamic load distribution between the primary and secondary evaporators. The system's control unit monitors real-time thermal demands and adjusts the contribution of each evaporator accordingly. For instance, during periods of low demand, the system may rely more heavily on the secondary evaporator to minimize energy consumption. Conversely, during peak demand, both evaporators may operate simultaneously to ensure adequate cooling.
[0065] According to one embodiment, this complementary operation between the primary and secondary evaporators not only enhances energy efficiency but also provides redundancy and resilience in the cooling system. The integration of these components allows the hybrid cooling system to adapt to a wide range of applications, from residential air conditioning to large-scale industrial cooling, offering a sustainable and cost-effective solution to modern thermal management challenges.7. Control System
[0066] Embodiments disclosed comprise the control system that ensures efficient, adaptive, and reliable operation. It dynamically manages the interplay between the primary and secondary cooling mechanisms, optimizing energy use and maintaining consistent cooling performance under varying thermal loads. The control system's advanced features enable real-time monitoring, intelligent decision-making, and precise adjustments, making it integral to its overall functionality.
[0067] At its core, the control system employs a network of temperature and pressure sensors strategically placed throughout the hybrid cooling system. These sensors continuously monitor key parameters such as the condenser's temperature, the compressor's operating pressure, and the thermal load requirements. This real-time data forms the foundation for the control system's ability to adapt its operation to current conditions.
[0068] Embodiments disclosed include one of the standout features of the control system is the incorporation of a proportional-integral-derivative (PID) controller. The PID controller processes the sensor data to regulate the operation of both the compressor and the adsorption chiller. By dynamically adjusting the compressor's speed and the adsorption chiller's cycles, the control system ensures that the cooling output matches the demand while minimizing energy consumption. This level of precision helps achieve high energy efficiency and extends the system's operational lifespan by reducing mechanical strain on components,
[0069] Preferred embodiments include a control system configured for dynamic load distribution between the primary and secondary evaporators. Depending on the thermal load and waste heat availability, the control system determines the optimal contribution from each evaporator, During periods of high demand, the control system may activate both cooling mechanisms fully, while during low-demand periods, it can prioritize the secondary evaporator to utilize waste heat efficiently, thus conserving energy.
[0070] The control system also facilitates the integration of auxiliary components, such as the thermal storage unit, which stores excess cooling capacity during off-peak hours. It orchestrates the charging and discharging of this storage unit, ensuring cooling availability during peak periods without overburdening the compressor or adsorption chiller.
[0071] According to a preferred embodiment, beyond operational efficiency, the control system enhances the system's reliability and safety. By continuously monitoring system parameters, it can detect anomalies such as excessive pressure or overheating and take corrective actions, such as reducing compressor output or temporarily shutting down specific components. This proactive approach helps prevent damage and ensures uninterrupted cooling performance. In summary, the control system is the intelligence behind the hybrid cooling System. Its ability to monitor, regulate, and optimize various components allows the system to deliver energy-efficient, adaptive, and sustainable cooling solutions for residential, commercial, and industrial applications.8. Thermal Storage Unit
[0072] An alternate embodiment further comprises athermal storage unit, an auxiliary component of the hybrid cooling system, designed to enhance its efficiency and adaptability by storing excess cooling capacity for later use. This innovative feature ensures that the system can meet peak thermal demands without overburdening the compressor or adsorption chiller, thereby optimizing energy consumption and improving overall performance.
[0073] The thermal storage unit is operatively connected to the secondary evaporator, which is associated with the adsorption chiller. During periods of low cooling demand, the adsorption chiller may produce more cooling capacity than is immediately required. Instead of letting this excess cooling output go to waste, the thermal storage unit captures and retains it in the form of chilled water or another phase-change medium. This stored energy is then available for use during periods of peak demand, allowing the system to maintain consistent performance without needing to ramp up the operation of the primary cooling mechanism.
[0074] According to an embodiment, the storage unit's design typically involves materials with high thermal conductivity and capacity, such as phase-change materials (PCMs) or water tanks with insulation. These materials allow the unit to efficiently absorb, store, and release cooling energy with minimal losses. Advanced insulation technologies ensure that the stored cooling capacity remains available for extended periods without significant degradation.
[0075] Embodiments disclosed include the control system, which plays a vital role in managing the operation of the thermal storage unit. By monitoring real-time thermal loads and system parameters, the control system determines when to charge the storage unit (store excess cooling) and discharge it (release stored cooling to meet demand). This dynamic integration ensures that the system operates efficiently under varying conditions.
[0076] According to an embodiment, the inclusion of a thermal storage unit provides several key benefits, First, it enables peak load shaving, which reduces the strain on the compressor and adsorption chiller during high-demand periods by improving energy efficiency and extending the lifespan of the system's core components. Second, the hybrid cooling system can take advantage of off-peak electricity rates by generating and storing cooling capacity during low energy costs. Finally, it enhances the system's resilience and reliability, ensuring uninterrupted cooling even during fluctuations in demand or temporary operational limitations of the primary and secondary cooling mechanisms.9. Solid Adsorbent Material
[0077] According to an embodiment, the solid adsorbent material is a crucial component of the adsorption chiller in the hybrid cooling system. It facilitates the adsorption-desorption cycle, enabling the system to generate secondary cooling by utilizing waste heat. Unlike conventional refrigerants used in vapor compression systems, the adsorbent material works by binding and releasing a refrigerant vapor (such as water, ethanol, or ammonia) through a thermally driven process. The choice of adsorbent material significantly impacts the efficiency and performance of the adsorption chiller. The most commonly used materials include:
[0078] Silica Gel: A widely used adsorbent that works effectively with water as the refrigerant. It operates efficiently at low regeneration temperatures (typically 60° C. to 100° C.), making it ideal for utilizing low-grade waste heat,
[0079] Zeolite: A crystalline aluminosilicate material with a high adsorption capacity. It can achieve higher temperature differentials and is more stable under varying humidity conditions. However, it requires slightly higher regeneration temperatures (100° C. to 150° C.).
[0080] Metal-organic frameworks (MOFs): A new class of highly porous materials that exhibit superior adsorption properties. MOFs can store and release large amounts of refrigerant while operating at lower temperatures, improving the efficiency of the cooling system.
[0081] According to one embodiment, in the adsorption cycle the solid adsorbent material captures refrigerant vapor during the adsorption phase, creating a cooling effect. Once the adsorbent reaches its saturation limit, waste heat from the condenser is applied to initiate the desorption phase, where the adsorbed refrigerant is released and recirculated. This cycle repeats continuously, providing efficient cooling without mechanical compression. The operating efficiency of the hybrid cooling system depends on the adsorption capacity, regeneration temperature, and thermal stability of the solid adsorbent material. By selecting the appropriate material, the system can achieve a Coefficient of Performance (COP) of at least 0.55 for the adsorption chiller and an overall system COP of 3.0 or higher.
[0082] Additionally, the multiple adsorption bed design ensures continuous cooling output by alternating between adsorption and desorption phases, preventing interruptions in cooling performance. This enhances the system's applicability for residential, commercial, and industrial cooling applications while reducing energy consumption and reliance on conventional refrigerants.
[0083] The hybrid cooling method operates as follows:1. Primary Cooling
[0084] A preferred embodiment of the method includes the primary cooling operation in the hybrid cooling system, centered on the compressor-based vapor compression cycle, which provides the foundational cooling mechanism. The method comprises compressing the refrigerant, significantly increasing its pressure and temperature. This high-pressure, high-temperature refrigerant is passed through the condenser, releasing heat to the surrounding environment or a secondary medium. As the refrigerant loses heat, it transitions from a gaseous state to a high-pressure liquid.
[0085] According to an embodiment, the refrigerant flows from the condenser into the expansion valve, which reduces its pressure, causing it to expand and cool rapidly. This low-pressure, low-temperature refrigerant enters the primary evaporator, absorbing beat from the load or the surrounding space. The absorption of heat by the refrigerant creates a cooling effect delivered to the target environment. The refrigerant, now in a gaseous state, is then returned to the compressor to repeat the cycle.
[0086] Further, the primary cooling cycle is dynamically regulated by the system's control unit. Equipped with temperature and pressure sensors, the control system monitors real-time conditions and adjusts the compressor's operation to match the cooling load requirements. For example, during periods of low demand, the compressor operates at reduced speeds to conserve energy, while during peak demand, it increases output to ensure adequate cooling. This primary cooling cycle not only provides direct cooling to the load but also serves as the energy source for the secondary cooling mechanism. The heat generated during the compression cycle is captured by the condenser and transferred via a heat exchanger to the adsorption chiller, enabling secondary cooling, By integrating primary and secondary cooling operations, the hybrid system achieves enhanced efficiency and sustainability.
[0087] In summary, the primary cooling operation forms the backbone of the hybrid cooling system, delivering efficient and reliable cooling while simultaneously supporting the system's energy-efficient secondary cooling cycle. This dual functionality makes the hybrid system adaptable to diverse thermal management applications, from residential air conditioning to industrial cooling.2. Waste Heat Utilization:
[0088] According to a preferred embodiment, waste heat utilization is a defining feature enabling enhanced energy efficiency and sustainability by repurposing heat generated during the primary cooling cycle to drive the secondary cooling mechanism. Instead of discarding the heat produced during the refrigerant compression cycle, the system captures and redirects it for productive use in the adsorption chiller. This approach significantly reduces energy wastage and minimizes the environmental footprint of the cooling operation.
[0089] The compressor generates substantial heat as a by-product of compressing the refrigerant. In conventional cooling systems, the condenser transfers this high-temperature heat and typically rejects it into the environment. In the hybrid cooling system, a plate-type heat exchanger is integrated with the condenser to capture this waste heat and transfer it to the adsorption chiller.
[0090] According to an embodiment, the adsorption chiller utilizes the waste heat to drive its adsorption-desorption cycles. During the desorption phase, the heat regenerates the silica gel-water working pair by evaporating the adsorbed water, allowing the silica gel to be reused in the next adsorption phase. This creates a secondary cooling effect, which complements the primary cooling provided by the compressor. By using waste heat as an energy source, the adsorption chiller operates without requiring additional external energy, making the system significantly more efficient.
[0091] Embodiments disclosed include the integration of waste heat utilization into the hybrid cooling system, which offers multiple advantages. First, it reduces the system's overall energy consumption by enabling dual use of the energy initially expended during compression. Second, it supports sustainability by lowering greenhouse gas emissions and reducing reliance on non-renewable energy sources. Finally, it enhances the system's adaptability by enabling it to respond effectively to varying thermal demands without increasing energy costs. Therefore, waste heat utilization is a cornerstone of the hybrid cooling system, By capturing and repurposing waste heat, the system achieves superior energy efficiency, reduces operational costs, and aligns with global goals for sustainable thermal management. This feature makes the hybrid cooling system ideal for various residential, commercial, and industrial applications.3. Secondary Cooling
[0092] A preferred embodiment of the method includes secondary cooling in the hybrid cooling system, achieved by integrating an adsorption chiller that utilizes waste heat recovered from the primary cooling process. This energy-efficient mechanism complements the primary cooling cycle by providing additional cooling capacity, enhancing the overall performance and sustainability of the system.
[0093] According to an embodiment, waste heat generated during the refrigerant compression phase of the primary cooling cycle is captured by the condenser and transferred via a plate-type heat exchanger to the adsorption chiller. The adsorption chiller utilizes a silica gel-water working pair to perform adsorption and desorption cycles. During the adsorption phase, silica gel adsorbs water vapor, creating a cooling effect as latent heat is removed from the vapor. During the desorption phase, the waste heat regenerates the silica gel by evaporating the adsorbed water, enabling the cycle to restart.
[0094] According to an embodiment, the cooling output from the adsorption chiller is delivered to the load through the secondary evaporator. This evaporator works alongside the primary evaporator, with the control system dynamically managing the cooling load distribution between the two. By leveraging secondary cooling, the system can reduce the burden on the compressor, particularly during periods of low to moderate thermal demand, thereby conserving energy and extending the lifespan of the primary cooling components.
[0095] One of the significant advantages of secondary cooling is its reliance on waste heat as the energy source, eliminating the need for additional electricity or fuel. This reduces the system's operating costs and environmental impact. Furthermore, including multiple adsorption beds within the adsorption chiller ensures continuous cooling output, addressing the inherent cyclic nature of adsorption-desorption processes. Simultaneously, the dynamic integration of secondary cooling into the hybrid cooling system allows it to adapt efficiently to varying thermal demands. For example, the primary and secondary cooling mechanisms work together during peak demand periods to ensure sufficient cooling capacity. During off-peak periods, the system may prioritize secondary cooling, maximizing waste heat utilization and minimizing energy consumption.
[0096] By utilizing waste heat to drive an advanced adsorption chiller, the system achieves superior adaptability and cost-effectiveness, making it an ideal solution for residential, commercial, and industrial applications.4. Dynamic Load Distribution
[0097] Embodiments disclosed comprise dynamic load distribution means, enabling allocation of cooling demands intelligently and efficiently between the primary and secondary cooling mechanisms. This capability ensures optimal energy utilization, consistent cooling performance, and real-time adaptability to varying thermal loads. The system's advanced control unit is at the core of dynamic load distribution and is equipped with temperature and pressure sensors strategically placed throughout the system. These sensors continuously monitor critical parameters, such as the thermal load, compressor output, and adsorption chiller performance. Based on this real-time data, the control unit dynamically adjusts the contributions of the primary evaporator (associated with the compressor) and the secondary evaporator (associated with the adsorption chiller) to meet the cooling demand efficiently,
[0098] According to a preferred embodiment, during periods of low thermal demand, the system prioritizes using the secondary cooling mechanism driven by waste heat from the primary cycle. This approach minimizes the compressor's energy consumption while maintaining sufficient cooling capacity. Conversely, during periods of peak demand, the control unit activates both the primary and secondary cooling mechanisms to ensure adequate cooling output. By balancing the load between the two evaporators, the system avoids overloading any single component, enhancing the reliability and longevity of the system.
[0099] Dynamic load distribution results in efficient energy management. leveraging the waste heat recovered from the primary cycle to power the adsorption chiller, the system reduces its dependence on electricity for cooling. This dual-cooling approach lowers operational costs and supports sustainability by reducing greenhouse gas emissions. Additionally, the system can integrate with a thermal storage unit, which stores excess cooling capacity generated during off-peak periods. The stored energy is then used during peak demand, optimizing load management.5. Thermal Storage
[0100] An alternate embodiment includes a thermal storage unit, designed to enhance adaptability and efficiency by capturing excess cooling capacity during periods of low demand and releasing it when thermal loads peak. This energy management capability ensures consistent cooling performance while reducing energy consumption and operational costs. The thermal storage unit is typically integrated with the secondary evaporator of the adsorption chiller. Excess cooling is directed to the storage unit when the cooling demand is lower than the system's output, particularly during off-peak periods. This stored energy is retained in chilled water or through phase-change materials (PCMs) that efficiently absorb and release thermal energy. Advanced insulation techniques minimize energy losses, ensuring the stored cooling capacity remains available for extended periods.
[0101] According to an embodiment, during peak demand periods, when the cooling load exceeds the real-time capacity of the primary and secondary cooling mechanisms, the system draws from the thermal storage unit to supplement its output. This reduces the burden on the compressor and adsorption chiller, allowing them to operate optimally and prolong their lifespan. The control system dynamically manages the charging and discharging of the thermal storage unit, ensuring seamless integration with the overall operation of the hybrid cooling system.
[0102] According to an embodiment, the thermal storage unit also enhances the sustainability of the hybrid cooling system. Maximizing waste heat utilization and reducing reliance on continuous compressor operation minimizes the overall carbon footprint of the cooling process. Additionally, using PCMs or water as storage media aligns with environmentally friendly and energy-efficient practices. Therefore, thermal storage is a critical component of the hybrid cooling system, providing flexibility, efficiency, and sustainability in managing thermal loads. The system balances energy conservation and consistent performance by capturing and reusing cooling capacity, making it ideal for residential, commercial, and industrial applications.
[0103] The hybrid cooling system offers a range of benefits that make it a superior choice for modern thermal management applications. Its innovative design integrates primary compressor-based cooling with secondary adsorption chiller technology, maximizing energy efficiency, adaptability, and environmental sustainability.
[0104] Embodiments disclosed significantly reduces energy consumption by utilizing waste heat from the primary cooling cycle to drive the adsorption chiller. This dual-cooling approach minimizes reliance on external energy sources, particularly during low thermal demand periods. Using a variable-speed compressor and dynamic load distribution further optimizes energy usage, ensuring that each component operates most efficiently. The system aligns with sustainability goals by repurposing waste heat and utilizing environmentally friendly working pairs, such as silica gel water. It reduces greenhouse gas emissions, reliance on fossil fuels, and the overall carbon footprint of cooling operations, making it an eco-friendly solution for residential, commercial, and industrial applications.
[0105] Additionally and alternatively, the hybrid design reduces the strain on individual components by distributing the workload between the compressor and the adsorption chiller. This balanced operation minimizes wear and tear, extending the lifespan of critical components such as the compressor and adsorption beds. The system can be customized to suit diverse cooling needs, from small residential setups to large industrial applications. Its modular design and scalability make it adaptable to a wide range of environments and thermal loads. The inclusion of a sophisticated control system with temperature and pressure sensors, coupled with a proportional-integral-derivative (PID) controller, ensures precise and efficient operation. Real-time monitoring and intelligent adjustments enable the system to maintain optimal performance and reliability.
[0106] The hybrid cooling system can be integrated with renewable energy sources, such as solar or waste heat recovery systems, further enhancing its sustainability and reducing dependence on conventional energy. The system's advanced features and innovative design offer unmatched advantages in terms of efficiency, sustainability, and reliability. These benefits make it an ideal solution for addressing the growing demand for energy-efficient and environmentally friendly cooling technologies in a wide array of applications.
