What is the difference of storage of cold dessert and hot dessert?
4 answers
The difference between the storage of cold desserts and hot desserts lies in the mechanisms employed. Cold storage systems, like a cold-stored cake box, utilize refrigeration plants, fans, and temperature detectors to maintain lower temperatures, preventing cakes from rotting during transportation. In contrast, hot storage systems, such as a cold and hot storage tank, incorporate diode refrigeration chips that produce heat during freezing operations, enabling simultaneous heating and cooling functions. Additionally, a cold/hot storage systemutilizes heat exchangers and circulation pipes to store hot or cool heat generated by refrigerator devices. These systems aim to reduce energy consumption by effectively storing and utilizing heat for maintaining desired temperatures in desserts, whether cold or hot.
How does direct air capture technology work in HVAC systems?
10 answers
Direct Air Capture (DAC) technology, when integrated into HVAC systems, operates by extracting CO2 directly from the atmosphere, leveraging the existing infrastructure of buildings to mitigate CO2 emissions efficiently. The process involves the adsorption of CO2 on specialized materials, such as amine-functionalized anion exchange resins, which capture CO2 from the air passing through the HVAC system. This is followed by a regeneration phase, where the captured CO2 is released from the adsorbent material for storage or utilization, allowing the adsorbent to be reused. Innovative approaches have been explored to enhance the thermal performance of DAC in HVAC systems, such as utilizing the evaporation/condensation heat from the vapor compression refrigeration (VCR) cycle. This method improves the efficiency of the adsorption/desorption process, making it more energy-efficient and effective in capturing larger amounts of CO2. Moreover, the integration of DAC with HVAC systems can lead to reduced ventilation needs in enclosed environments, such as commercial buildings, by maintaining air quality through CO2 capture. This results in a significant decrease in energy loads on the HVAC systems, demonstrating a dual benefit of CO2 capture and energy savings. The application of DAC technology in HVAC systems also explores the use of calcium sorbents for CO2 capture through chemisorption, offering a pathway for low-cost, wide-scale implementation. The captured CO2 can either be sequestered or regenerated, with the carbonated sorbent being reused or disposed of. Overall, the integration of DAC technology into HVAC systems presents a promising solution for reducing atmospheric CO2 levels while leveraging existing building infrastructure. This approach not only addresses the challenge of direct CO2 removal from the atmosphere but also contributes to the energy efficiency of buildings, showcasing the potential of DAC technology in contributing to climate change mitigation efforts.
