请问各位高手下面一个题应该选什么？ The low-side gauge reads 40psi: the high-side gauge reads 150 psi: the auxillary gauge reads 5psi. Ambient air temperature is 80F(温度计量单位)，the system has an evaporator pressure control valve and cools poorly. the cause could be: a. a bad condenser b. damaged compressor reed valve c. both a and b d . Neither a and b 另，如果低端值为1，高端值为200，温度值为100时，又会是什么原因，这几个数值有什么关联？看完书后还是百思不得其解。 特此向高手求教。 |

我的意思是没有说是R12还是R-134a. <BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR>Originally posted by Lincesl: 关键的问题是原题没有写明是针对哪一个牌号的制冷剂，所以你的问题没法回答。 <BLOCKQUOTE class="ip-ubbcode-quote"><font size="-1">quote:</font><HR>Originally posted by gogo: 正常参考值是多少？<HR></BLOCKQUOTE><HR></BLOCKQUOTE> |
