Ac For Buses Supplier stated that electric heat pump air conditioning systems for buses offer significantly higher heating efficiency than PTC systems. As bus electrification continues, the requirements for heat pump air conditioning systems in buses are becoming increasingly stringent.
Heat pump air conditioning is evolving towards environmental friendliness, energy saving across all scenarios, and adaptability to extreme environments. Research and development are underway for new alternative refrigerants and high-efficiency heat pump air conditioning systems and components, such as supercritical CO2 heat pump air conditioning, new high-efficiency supplementary gas compressors, and high-efficiency microchannel heat exchangers, to address issues such as high heating energy consumption and insufficient capacity. New heat pump air conditioning systems suitable for extreme environments (extreme cold, extreme heat, high humidity, high salinity) are being developed to improve the overall vehicle’s adaptability.
Heat pump air conditioning systems are also evolving towards vehicle thermal management, meeting the needs of the entire vehicle and responsible for the thermal management of the battery system, motor, and power devices, ensuring the system operates within its optimal temperature range and improving energy efficiency and reliability.
Heat pump air conditioning is evolving towards intelligent systems, monitoring ambient temperature and humidity, in-vehicle temperature and humidity, outlet air temperature, battery temperature, water temperature, refrigerant temperature and pressure, in-vehicle CO concentration, and PM2.5 levels, and adaptively adjusting the electric actuators to achieve energy efficiency and comfort.
Ac For Buses Supplier stated that with the application of superior environmentally friendly refrigerants, improved compressor efficiency, optimized heat exchanger performance, air conditioning piping, and system design, especially breakthroughs in supercritical CO heat pump technology, the environmental adaptability, comfort, and intelligence of electric vehicles will continuously improve. In the future, heat pump air conditioning for electric vehicles will experience rapid development, becoming a significant driving force for the development of the electric vehicle industry.
