Cooling And Heating Defroster For Electric Car
Products Description

For new energy buses without an engine-based heat source, traditional heating-only defrosting systems have major drawbacks: they can clear frost in low temperatures, but they often worsen fogging in humid or rainy conditions and cannot cool the driver's cabin in summer.
Integrated electric heating and cooling defrosting units-designed specifically for bus cabins-effectively resolve these issues and are widely used in electric city buses, tourist coaches, and fuel-cell school buses.

This unit features an integrated assembly design that combines a high-voltage PTC heating core, a cooling evaporator, a high-flow brushless fan, and an electronically controlled damper actuator. It operates on the vehicle's high-voltage power supply with 24V low-voltage control, supporting both local panel operation and CAN-J1939 bus compatibility. It integrates with the vehicle's thermal management system, working in coordination with the BTMS, electronic water pumps, and electronic three-way valves to utilize waste heat and reduce energy consumption associated with electric heating.
Products Application
1. New Energy Buses and Coaches
2. New Energy Commercial Vehicles
3. Special-purpose Construction Vehicles
4. Recreational Vehicles (RVs) and Specially Modified Vehicles

Products Details




Climate and environmental scenarios
1
Low-temperature areas such as Northern Europe and Russia. In winter, when heavy snow and frost cover the windshield, the device activates a hot-air mode to rapidly melt frost while raising the glass surface temperature, thereby delaying re-icing.
2
Plum rain seasons and humid coastal environments. Traditional heating-only defrosters often worsen fogging; this device first cools and dehumidifies the air before blowing out warm air, eliminating window fogging at the source and ensuring clear visibility for the driver.
3
The device can output cool air to lower the cabin temperature, preventing fogging caused by the temperature difference between the interior and exterior of the windows.
