Speed ​​requirements should be fully considered when determining the compressor cooling capacity
The multi-operating point operation of passenger car air-conditioning compressors, and the application of multiple speed changes determine that the compressor design conditions can also be determined according to the conditions of the vehicles that are designed to operate locally, and are not completely in accordance with relevant industry standards. The specified operating conditions of the vehicle air conditioning system. The speed of the city bus and the long-distance tourist transport bus is different. Most of the city buses are driven at the speed corresponding to the compressor speed in the left and right tourist transport buses (the corresponding compressor speed is above), so the compressor is marked in the measurement. The cooling rate should be fully considered in terms of speed. What are the general requirements for the development of recommended product standards for passenger car air conditioning compressor standards, and what kind of test methods are used to verify them. There are no technical conditions for a single test method that do not have a complete meaning. According to the experience of the establishment of the compressor enterprise standard for automotive air conditioning, the following suggestions are proposed for reference to the compressor working conditions. The compressor should be able to work reliably for a long time under the design and use conditions specified in the table. Decay compressor design and use condition Item value Maximum exhaust pressure saturation temperature Maximum pressure difference (maximum suction pressure saturation temperature maximum exhaust temperature use temperature range - compressor in the horizontal plane tilt angle longitudinally to determine the nominal cooling capacity of the compressor The nominal refrigeration condition of the compressor is the numerical value of the suction pressure, the saturation temperature, the exhaust pressure, the saturation temperature, the suction temperature, the refrigerant temperature, the compressor speed, the cooling capacity requirement of the long-distance passenger bus compressor in the city bus. The cooling capacity of the compressor is specified according to the table. The working condition, the cooling capacity should not be lower than the designed value of the cooling capacity including the cooling capacity of the refrigerant in the suction pipe refrigerant. The unit cooling capacity of the compressor according to the working conditions specified in the table, the unit power cooling capacity should not The input power of the compressor below the design value shall not exceed the input engine driven by the auxiliary engine driven by the design according to the specified operating conditions of the table. Compressor pressure tightness lubrication safety reliability Requirements: The parts of the compressor that are subjected to high pressure and low pressure should be subjected to pressure test and air tightness.
