Computer Data Acquisition Hardware Analysis of Low Temperature Heating Characteristics of New Energy Vehicle Supplementary Air and Enthalpy Low Temperature Heat Pump Air Conditioning System

In this paper, a set of supplementary air-enhanced heat pump air conditioning system that can operate under variable conditions at low temperatures is designed for new energy vehicles. The system is based on the principle of quasi-two-stage compression. The indoor temperature, the heating performance bench experiment was carried out under the condition of changing the outdoor ambient temperature of the car, and the structure optimization simulation study of the liquid distributing component was carried out by using Fluent. The optimized liquid distributing head and the distribution pipe had different distribution unevenness. Reducing to 31.369% and 29.003% of the original dispensing head and the original distribution pipe, the heat transfer of the inside heat exchanger and outside heat exchanger can be increased by 2.347% and 8.704%, respectively.
