车辆的空调发展很快。现在日本首都范围内的车辆空调的比率平均已达到85％。以前的车辆空调是开、关控制的,所以空调机组不可能在高精确度的控制下运转。在外气温度低的梅雨季节,不能进行除湿运转,致使车内闷热,因此就需要对空调的机能进行进一步的改进。另外,随着微处理机技术和逆变器变速控制技术的发展,已能适用于提高车内舒适性的需要,可使车辆空调装置的空调效果由
Air conditioning has developed rapidly. At present, the ratio of vehicle air conditioners in Japan’s capital has reached an average of 85%. The previous vehicle air-conditioning was on and off control, so the air-conditioning unit can not operate with high accuracy control. In the meiyu season with low outside air temperature, the dehumidification operation can not be performed, causing the car to be hot and humid. Therefore, further improvements of the air conditioning function are required. In addition, with the development of microprocessor technology and inverter speed control technology, has been able to apply to improve the comfort of the car needs, air conditioning can make the vehicle air conditioning effects from
