In order to analyze the temperature controlling stability in the cabinet and energy-saving effect of the refrigeration showcase using electronic expansion valve,the temperatures in the cabinet and power consumptions of the refrigeration showcase using electronic expansion valve and thermal expansion valve are tested.The results show that using electronic expansion valve,the temperature in the refrigeration showcase decreases very fast and the temperature fluctuation range is small.In addition,it can save about 4.46%of power consumption compared with that using thermal expansion valve.
