“Thirteenth Five-Year Planâ€, energy saving, emission reduction and light weight are the development priorities of the automotive air conditioning industry. This article refers to the address: http:// â– Automotive air conditioning is most important for energy efficiency “Currently, the entire automotive air-conditioning industry is at a low-speed development stage. Among them, independent brands are more affected than foreign brands.†Yu Yuanjun, former secretary general of China Automotive Air Conditioning Association, told reporters that due to the slowdown of the entire automobile industry, cars The air-conditioning industry is also affected, and independent brand air-conditioning enterprises should upgrade their industries as soon as possible to achieve healthy development. "Made in China 2025" clearly pointed out the strategic goals of energy conservation and new energy vehicle industry development. Among them, in terms of energy-saving vehicles, by 2020, the overall fuel consumption of new passenger cars will drop to 5 liters / 100 kilometers. By 2020, the fuel consumption of new commercial vehicles will be close to the international advanced level. Yu Yuanjun said that the “Thirteenth Five-Year Plan†is the first five years of the “Made in China 2025†ten-year plan. Energy saving and consumption reduction cannot be delayed, and the fuel consumption of the whole vehicle should be reduced from various parts and components. Contribute to reducing vehicle fuel consumption. According to Yu Yuanjun, by 2020, the contribution rate of the air conditioning system to the fuel economy of the vehicle should reach 0.2 liters / 100 kilometers to 0.3 liters / 100 kilometers of oil. Time is tight and tasks are heavy. Yu Yuanjun said that the air conditioning system should be upgraded from the following three aspects: First, the external control variable displacement compressor should be used for the compressor; at the same time, the microchannel high efficiency radiator should be adopted; the high efficiency energy saving fan also becomes an upgrade essential. In short, high-efficiency air-conditioning is getting more and more attention. The United States, the European Union and Japan have done relatively early on high-efficiency air-conditioning. Therefore, independent brands should also accelerate research and application in energy-efficient air-conditioning, and strive to reach the international advanced level in this regard as soon as possible. When talking about the issue of air conditioning energy saving and efficient technology development, Wei Changhua, general manager of the air conditioning division of Jiangsu Chaoli Group, pointed out that Superpower uses a regenerative heat exchanger to make the high temperature, high pressure refrigerant at the outlet of the condenser and the low temperature and low pressure at the outlet of the evaporator. The refrigerant exchanges heat in the double-walled pipe to improve the refrigeration performance. At the same time, it cooperates with the compressor company to develop the externally controlled variable displacement compressor and control system. Subsequently, the oil separator will be added to the compressor to reduce the compression in the refrigerant. Machine oil to improve air conditioning cooling performance. Conventional car heating uses engine heating and insufficient heating in alpine regions. Therefore, Superpower combines the requirements of refrigeration and defrosting to develop internal and external gas control strategies to improve and enhance comfort and energy saving effects. â– Air conditioning electrification has become the focus of development The new energy automobile industry has risen rapidly, and the air conditioning system that matches new energy vehicles has become one of the priorities of many air conditioner companies in the future. "One of the important routes for the development of automotive air-conditioning in the future is the electrification of air-conditioning, and its electrification will also develop in many directions." Qian Yonggui, general manager of Nanjing Aotejia New Energy Technology Co., Ltd. told reporters. Qian Yonggui explained that first of all, new energy vehicles naturally use electric air conditioners. Secondly, traditional vehicles will also face the need to continuously improve energy-saving levels. The start-stop system can increase the energy-saving level and requires air-conditioning and electric coordination. Third, it requires truck air-conditioning. Electricized, when the truck is parked and closed, the engine is turned off, and the electric air conditioner is used, which can greatly save fuel consumption. Finally, the passenger car air conditioner is electrified, and the passenger car multi-temperature zone electric air conditioner can open a temperature zone or multiple temperatures according to the number of people on the bus. Zones can be precisely controlled to avoid wasting fuel. In addition to the popularization of high-efficiency air conditioners on a number of models, the electrification of automotive air conditioners has to be further improved in technology. Wei Changhua believes that the current R134a refrigerant has a small volume per unit volume, a high boiling point, and a low evaporation pressure at low temperatures, which limits the improvement of energy efficiency and the development of low temperature heating. Therefore, the development of a high-efficiency medium- and high-temperature refrigerant has become a trend in the development of electric vehicle air conditioners. The new refrigerant R410a compressor has a small displacement and uses an electronic expansion valve to increase the pressure resistance by about 37%. "With the development of new energy technologies, the thermal management of automotive air conditioning systems and vehicle power (engine, battery and motor) systems will be deeply integrated. Automotive air conditioning companies will further develop into vehicle thermal management systems." Yuxin Automotive Air Conditioning Hou Yuguang, deputy general manager of the company. â– Targeting trends to develop new products The development trend of the automotive air-conditioning industry during the “13th Five-Year Plan†period has become clear, and automotive air-conditioning companies are also preparing to develop related products and systems. Wei Changhua said that at present, the driving range of new energy vehicles has become the focus of public attention. Air conditioners, as a major consumer of electricity, have become the primary task of electric vehicle air conditioners. In order to achieve energy saving, Superpower has developed products such as high-efficiency heat exchangers and battery thermal systems for controlling air-conditioner blowers and brushless air-conditioner blowers using PWM (Pulse Width Modulation Power Controller) for energy saving of vehicles and further technology for new energy vehicles. upgrade. In order to meet the demand of the “13th Five-Year†new energy vehicles and solve the problem of the energy consumption ratio of heat pump air conditioners in the cold regions, Chaoli cooperated with foreign institutions to promote the development of heat pump air conditioning systems and components suitable for use in alpine regions. For the future solution of electric vehicle air conditioning heating, the product given by Altega is a heat pump type electric compressor. Qian Yonggui said that the current electric vehicle heating uses PTC heating, which is a large power consumer of electric vehicles. The opening of warm air conditioning in winter has a great impact on the continued driving of electric vehicles. The heat pump electric compressor developed by Aotejia can still heat up when the temperature outside the car reaches -15 °C, and improve the driving range. The "Key Technology Development and Application of High-efficiency Electric Air Conditioning (Heat Pump) Compressor for Automobiles" won the "First Prize of China Machinery Industry Science and Technology 2015". Hou Yuguang said that with the promotion and popularization of new energy vehicles, Yuxin will also seize the opportunity to cooperate with “Electric Coffee†to develop new energy vehicles, focusing on the development of new air conditioners (heat pump air conditioners, etc.) and power (batteries, motors). Etc.) Thermal management and critical thermal components, actively expanding remote intelligent control and diagnostic products based on vehicle thermal systems and air purification technologies. On this basis, Yuxin provides customers with a total solution for the entire vehicle thermal system.
