Experimental performance analysis of hybrid air conditioner in cooling season

IoT-Based Air Conditioning Control System for Energy Saving

“…Furthermore, these energy savings were higher than the adaptive model conserved energy, 8.6% [6], stratum ventilation, 6.4% [12], split-type AC evaporative cooling of condenser,4%-12.4% [14], and BEV balance on energy-saving and thermal comfort, 10% [15]. Nevertheless, these energy savings were in ranges to extended utilizing air re-circulation, 11%-30% [7], 15% on lightweight thermoelectric, [9], energy efficiency improvements in three cities, 12.3%, 38.5%, and 221.9% [13], AC included home appliances using a hybrid PV, diesel generator and batteries, 20% [16] and using PCRC, 18% [20]. Thus, it is no doubt that the automatic operation system saved consumed energy which was the third contribution.…”

“…However, these values of percentage energy saving are more significant than that of the adaptive model, 8.6% [6], with stratum ventilation, 6.4% [12], and 4%-12.4% power saving using the condenser evaporative cooling of split-type AC [14]. Nevertheless, these values were in ranges or around utilizing air extended driving range re-circulation, 11%-30% [7], lightweight thermoelectric, 15% [9], 12.3%, 38.5%, and 221.9% energy efficiency improvement [13], IoT for computer rooms, 16.64% [28], IoT prototype in the HVAC system, 20% [29], and 16.4% energy saving utilized chilled water loop and air handling process [32].…”

“…It spent 35%-42% more electricity for householders [2], and even HVAC is utilized to provide grid services [3]. Many efforts on energy saving of air conditioning systems have been conducted, such as dynamic setting temperature, 59.1% of energy consumption saving [4], ventilation and variation law of 30% reducing energy consumption [5], 8.6% of conserved energy of adaptive model [6], 11%-30% extended driving range of utilizing air re-circulation [7], 38% reduced electric energy of M-cycle evaporative cooling [8], 15% potential energy saving of lightweight thermoelectric [9], 50% recover energy of exhausted air [10], PCA-GMMs has 99% fault diagnosis correct rates [11], 6.4% reducing energy consumption with stratum ventilation [12], 12.3%, 38.5% and 221.9% energy efficiency improvements in three cities [13], 4%-12.4% decreasing power consumption using a evaporative cooling of condenser of a split-type AC [14], balance on energy saving and thermal comfort on a BEV by 10% slow down, energy gain reached 2.2 kWh [15], and 20% reducing fuel consumption on home appliances (including ACs) using a hybrid PV, diesel generator and batteries [16].…”

Модель Повітроочисника З Фільтрувальними Вставками НЕРА 11 Та Теплообмінником Нагріву Зовнішнього Повітря В Рециркуляційній Секції

“…До недоліків вже існуючих систем належить циркуляція повітря в кімнаті лише в зоні встановлення приладу або, навпаки, висока швидкість руху повітря в приміщенні[13], що призводить то втрати теплового комфорту [14]. Дослідження з встановленням теплообмінника в повітроочищувач в більшості випадків являють собою гібриди, експериментального зразку, охолоджуючого пристрою [15], чи осушувача з фільтрувальною частиною [16], [17], для наших температурних умов цікавить саме робота повітроочищувального пристрою при низьких температурах ,з високим перепадом між температурами зовнішнього та внутрішнього приміщення. Відносно невеликі робочі температури та значні перепади температур гарячого та холодного повітря, створює певні складнощі під час вибору теплообмінника та його конструкції [18].…”

Investigation of Fresh Air-Intake Split Air Conditioner Indoor Unit

“…The fact that Covid-19 is a virus transmitted directly by breathing and affects the respiratory system revealed the importance of having a system that will provide fresh air to the ambient air in split air conditioners in the air conditioning sector. Researchers showed that fresh air intake plays a vital role in the indoor air quality of living areas (Yang et al, 2021). Ho et al (Hoa et al, 2021) investigated the position of fresh air vent effects on airflow to maintain the room at 22 ⁰C for cooling function.…”
