two-spool compressor

The result shows that the defrosting period of machine with electronic expansion valve is 12 seconds or 11% shorter than that with thermal expansion electronic valve, so suggests integrating both two methods by using the electronic expansion valve and defrosting by reversing four-way valve with compressor off.

结果表明：采用电子膨胀阀的除霜时间比热力膨胀阀的短12s，即减少11%。
