The invention discloses an air adjusting device capable of meeting requirements of a direct-current 270V power source and a direct-current 26 V power source. The air adjusting device comprises a refrigerating system, a ventilating system and an electronic control system. The refrigerating system comprises a compressor, a condenser and an evaporator. The ventilating system comprises an evaporating fan and a condensing fan. The electronic control system comprises the direct-current 270 V power source, the direct-current 26 V power source, a power source converter, a control system body and a protecting system. The direct-current 270 V power source is connected with the power source input end of the compressor through the power source converter. The direct-current 26 V power source is connected with the power source input ends of the evaporating fan and the condensing fan. The protecting system comprises a temperature sensor arranged in the indoor air return position of air conditioning equipment. The temperature sensor is electrically connected with the compressor through the control system body. The air adjusting device is simple in structure, convenient to install, low in fault rate and high in reliability, variable-frequency soft starting and driving on the compressor are achieved, and air adjustment can be achieved efficiently; in addition, the refrigerating system can be effectively protected, and energy is saved.
Description
technical field [0001] The invention relates to the technical field of air conditioning of air conditioners, in particular to an air conditioning device capable of satisfying DC 270V and 26V power supplies. Background technique [0002] 270V high-voltage DC has become the first choice for the power supply system of electronic control systems in the future because of its high efficiency, high reliability, light weight and many other advantages. At present, many special vehicles have adopted 270V and 26V power supply mixed power supply. How to use 270V power supply method in a hurry? The realization of refrigeration and other technologies under the high-voltage DC power supply system puts forward new requirements for the air-conditioning device. The air-conditioning device uses an evaporative compression type to achieve refrigeration. Driven by a DC 270V power supply, the evaporating fan and condensing fan need to use 26V. Usually, electric compressors are directly driven by ...
