description: With the development of science and technology, new energy vehicles have also begun to enter the field of vision of mankind, and gradually enter the market, especially the emergence of electric vehicles, which has become a trend in the future development of the automotive industry. In this case, it is also very important to have a comfortable climate control system in the car. But ordinary fuel vehicles can brave the engine cooling water or the rmistor heating to provide heat, while electric vehicles can only be heated by a heat pump or tubular electric heater (TEN) because they do not have an engine, and this method consumes about 30%-40% of the electrical energy. Therefore, we select an efficient and inexpensive heat pump system for research. We choose the electric vehicle heat pump system using R134a as the refrigerant. Taking small and medium sized electric vehicles as an example, we have developed a heat pump system that can be used in cold conditions to meet the indoor temperature while maintaining the driving distance of electric vehicles. First, we calculate the thermal load of electric vehicles in winter conditions, and then determine the efficiency indicators, that is, at a temperature of minus 15Â°C, the heat pump system can generate more than 7000W of heat, so that the indoor temperature of the electric vehicle can reach 25Â°C, and the energy efficiency ratio of the heat pump system is greater than 2.0.Then determine the cyclical conditions of the system from the results of the calculation, and then select and match the compressor and specify the design parameters of the compressor
