五、制冷性能、及其改进措施HFC—134a和CFC—12的制冷性能比较已有不少报道,其大部分测试是在为CFC—12设计的车辆中进行的。由于获得了HFC—134a更多的数据,可以改进设计,在这些测试中得出的不足之处可能会得到减少或消除。
V. PERFORMANCE OF REFRIGERATION AND IMPROVEMENTS There have been many reports comparing the refrigeration performance of HFC-134a and CFC-12. Most of the tests have been conducted on vehicles designed for CFC-12. With more data from HFC-134a, designs can be improved and the deficiencies in these tests may be reduced or eliminated.
