• The Tesla Model 3 uses an electric air-conditioning compressor to regulate the temperature inside the vehicle. Its electric air-conditioning system is deeply integrated with the vehicle's thermal management system. In summer, the electric air-conditioning compressor cools efficiently, ensuring that the temperature inside the vehicle can be quickly reduced and maintained within a comfortable range. Meanwhile, this system can also recover some waste heat to preheat the battery, enhancing battery performance. In winter, through the coordinated work of heat pump technology and the electric air-conditioning compressor, heat is absorbed from the environment, motors, batteries and other components to provide heating for the cabin, effectively alleviating the significant reduction in the driving range of pure electric vehicles in winter.
• For example, in cold weather, the electric air-conditioning compressor of the Tesla Model 3 can extract heat from the residual heat of the battery and motor at an ambient temperature of -10°C to provide sufficient heating for the inside of the vehicle. Compared with the traditional electric heating method, the energy consumption is reduced by about 30%, resulting in a reduction in the loss of the vehicle's driving range in winter.
• The electric air-conditioning compressor of the BYD Han EV is a key component of its intelligent temperature control system. This compressor can precisely control the cooling capacity. During the vehicle's driving process, it adjusts the cooling or heating power in real time based on the data fed back by the temperature sensors and light sensors inside the vehicle. When the vehicle is traveling in a high-temperature environment for a long time, the electric air-conditioning compressor can maintain a stable running state, ensuring the comfort of the passengers inside the vehicle.
• In addition, in terms of battery thermal management, the electric air-conditioning compressor cooperates with the coolant circulation system to control the battery temperature within an appropriate range, improving the safety and service life of the battery. For example, when the battery temperature is too high, the compressor works to lower the temperature of the coolant, thereby removing the excess heat generated by the battery and ensuring that the battery temperature is always maintained between 25 - 35°C.
• The new energy buses of Yutong are equipped with efficient electric air-conditioning compressors. In the urban bus operation scenario, although the vehicles start and stop frequently, the electric air-conditioning compressors can respond quickly to provide a comfortable riding environment for the passengers inside the vehicle. For example, on a hot summer day, the electric air-conditioning compressor can reduce the temperature inside the vehicle to a comfortable level within a short time after the vehicle starts.
• Moreover, in the parked state, the driver can use the parking air-conditioning function of the electric air-conditioning. The electric air-conditioning compressor uses the vehicle's battery pack to supply power and provides cooling or heating for the inside of the vehicle, avoiding the fuel waste and environmental pollution caused by the engine idling. Taking a Yutong pure electric bus as an example, when the parking air-conditioning is turned on for one night (calculated as 8 hours), the power consumption is about 10% - 15% of the total battery capacity of the vehicle, and the cost is significantly reduced compared with that of a traditional fuel vehicle idling with the air-conditioning on.
• The electric air-conditioning compressor in a medical ambulance is of vital importance. It creates a comfortable temperature environment for the patients and medical staff inside the vehicle and ensures the normal operation of medical equipment. During the transportation of seriously injured patients, the electric air-conditioning compressor can keep the temperature inside the vehicle stable between 22 - 25°C, providing good conditions for maintaining the vital signs of the patients and medical treatment.
• For example, some advanced medical ambulances are equipped with an electric air-conditioning system with a purification function. The compressor works in coordination with the air purification device to filter bacteria and impurities in the air while adjusting the temperature, effectively preventing wound infections of the patients and improving the quality of medical rescue.
• When a fire engine is on a mission, the electric air-conditioning compressor can ensure the comfort of the firefighters inside the vehicle. Even in a high-temperature or harsh environment, it can keep the cockpit and crew compartment at an appropriate temperature. Meanwhile, for the various electronic and communication devices carried on the fire engine, the temperature control system assisted by the electric air-conditioning compressor can prevent the devices from being damaged due to overheating.
• For example, at a fire scene where the ambient temperature may be as high as 50 - 60°C, the electric air-conditioning compressor inside the fire engine can work normally to control the temperature inside the vehicle below 30°C, ensuring that the firefighters can operate the devices in a comfortable environment and improving the efficiency of fire fighting.
• Some small mobile air conditioners of Midea use electric air-conditioning compressors. This type of mobile air conditioner can be conveniently moved and used in different rooms without a complicated installation process. The electric air-conditioning compressor enables the mobile air conditioner to cool quickly, which is suitable for small spaces such as kitchens and studies.
• For example, in a kitchen with an area of 10 - 15 square meters, the electric compressor of the Midea mobile air conditioner can reduce the indoor temperature from 30°C to about 26°C within 10 - 15 minutes after being turned on, providing a cool environment for users during cooking and other activities in the hot summer.
