In the field of transportation, whether it is the comfortable experience of long-distance buses or the efficient operation of truck cold chain transportation, a key technology is indispensable-PTC heater. This seemingly inconspicuous equipment is actually the core guarantee for the stable operation of bus air conditioning and truck refrigeration units.
In the bus air conditioning system, PTC heater can be called “warm guard”. In cold weather, when passengers board the bus, the PTC heater begins to play a heating function. It is installed in the air duct of the air conditioning system. After power is turned on, it quickly generates heat. When the cold air passes through, it is quickly heated and evenly sent into the car through the air conditioning outlet, raising the temperature in the car to a comfortable range. Not only that, frosting and fogging of the windshield is a common problem when driving in winter. The PTC heater can complete the defrosting and defogging work in a short time by heating the windshield or the air in the car, providing the driver with a clear view and ensuring driving safety. According to statistics, the bus air conditioning system using PTC heater can increase the heating efficiency by 30% and shorten the defog time by about 40%.
In the truck refrigeration unit, the PTC heater plays the role of “system guardian”. In extremely cold areas, key components of the refrigeration unit, such as the battery and electronic control system, are prone to performance degradation or even failure due to low temperature. The PTC heater maintains a suitable working temperature for these components through auxiliary heating to ensure the normal operation of the refrigeration unit. In addition, evaporator frosting is a major problem affecting the refrigeration effect. In the defrosting mode, the PTC heater can quickly heat the evaporator surface and melt the frost layer quickly. Compared with the traditional defrosting method, the efficiency is increased by about 25%, which greatly improves the stability and reliability of cold chain transportation.
Whether it is the comfortable experience pursued by bus air conditioning or the efficient operation emphasized by truck refrigeration units, PTC heaters have become indispensable and important components with their automatic constant temperature, safety and energy saving. It not only improves the performance of transportation equipment, but also ensures the safety and comfort of passengers and goods, demonstrating the powerful power of science and technology in the field of transportation.
