High-Efficiency HVAC System with Defog/Dehumidification Function for Electric Vehicles

Blog Article

Electric vehicles (EVs) generally use an electric heating system to provide heat.However, the heating system consumes a large amount of energy, and therefore reduces the mileage of the vehicle.The energy consumption can be reduced by replacing the electric heating system with a heat pump air conditioning system.

Such systems achieve an effective heating of the vehicle interior, but do not provide a defog or dehumidification function.Consequently, the inside surface of the windshield tends to fog chiggate.com in cold weather; leading to poor driver visibility and an impaired road safety.Accordingly, the present study animed blue lotion topical spray proposes a novel high-efficiency heating, ventilation and air conditioning (HVAC) system with both heating and defog/dehumidification functions for electric vehicles.

The effectiveness of the proposed system is investigated experimentally using a simulated cabin placed in a temperature and humidity-controlled test chamber.The experimental results confirm that the HVAC system achieves the required cooling, heating and defog/dehumidification functions and meets the corresponding standards.Moreover, the application of HVAC in EVs could lead to significant electrical power saving effect.
