DC-AC Inverter and charge in one
● Choose KME pallet type air conditioner , more solar panels can be installed on the roof
Indoor unit
● High-grade engineering plastics are applied which has strong UV resistance , and it will not deform and change color after long-term use；
● The double drain pipes on the left and right sides can quickly drain water even when the vehicle is tilted;
● Four high-efficiency vehicle air outlets , all of which can be adjusted independently;
Refrigerant pipe
● High-strength vehicle rubber pipe from famous German brands,anti-vibration,anti-aging；
● The indoor and outdoor unit are connected by flexible pipe,which can meet long-term vibration requirements;
● Length of pipe can be customized;
Outdoor unit
● Famous brand dual-rotor compressor and self-developed intelligent energy saving control module ,more save energy；
● Small volume , Install easily；
● IP Grade: IPX7 (can be soaked for 30 minutes in a meter of water)；
● Meet 4.5g vibration acceleration；
● The height of vehicles isn't increased by pallet type outdoor units；
KME vehicle full DC inverter air conditioners, can be directly powered by the original Vehicle generator or living cabin battery , without DC-AC inverter, which reduces the loss of electric energy during the inverter process, and is more efficient.
Advantages of 48V DC vehicle air conditioners:
Low-voltage operation: 48V vehicle AV can work normally at lower voltages and adapt to the power systems of special vehicles such as RVs，truck，engineering vehicle.
Energy saving and environmental protection: 48V vehicle air conditioners use low-voltage DC power supply, which can reduce energy consumption and impact on the environment, and is in line with the trend of energy conservation and environmental protection.
Silent and comfortable: Using advanced refrigeration technology and sound insulation design, it provides good cooling effect while keeping the room quiet and comfortable.
Stable performance: The 48V vehicle air conditioner is specially designed to maintain a stable cooling effect while the vehicle is driving, without being disturbed by external factors. It uses advanced compressor and refrigeration technology to quickly cool down the air in the car in a short period of time, bringing users a more comfortable driving experience.
Flexible installation and maintenance: Because it uses low-voltage DC power supply, the installation process is simpler and faster. There is no need to make major changes to the vehicle's original power system, which reduces the installation difficulty and cost. At the same time, the maintenance of 48V vehicle air conditioners is relatively simple. Users can keep the air conditioning system in good operating condition, extend its service life, and reduce maintenance costs through simple cleaning and regular inspections.
Durable and reliable: Using high-quality materials and advanced technology, it has a long service life and good reliability, reducing maintenance costs.
Maintenance of 48V vehicle air conditioner:
Regular cleaning: Clean the air conditioning filter to ensure smooth air circulation and avoid dust and impurity clogging that affects the cooling effect.
Check the refrigerant: Regularly check the pressure and filling amount of the refrigerant to ensure the normal operation of the refrigeration system. Add or replace the refrigerant in time when necessary.
Check electrical connections: Regularly check electrical connections and wiring to ensure they are secure and to avoid air conditioning system failure due to electrical faults.
Regular maintenance: According to the frequency of use and environmental conditions, perform regular maintenance on the air conditioning system, including cleaning the radiator, checking the working status of the compressor and motor, etc.
Pay attention to waterproofing and dustproofing: Pay attention to waterproofing and dustproofing during use to prevent water vapor and dust from entering the air conditioning system and affecting its normal operation.
Pay attention to safe use: During maintenance, be sure to pay attention to safety to avoid electric shock and other accidental injuries.
