Abstract： In order to make the control strategy of the refrigerator with inverter adopt to complex and variable condition better，the experiment was conducted in an investigation of some influencing factors of performance of a refrigerator with inverter. Refrigerator with two temperature was taken as experiment object，and the refrigeration temperature was used as the control objectives，under the variable condition of different ambient temperature and compressor speed，based on the relationship between the refrigerating capacity and heat load；the effect of the factors of ambient temperature and compressor speed on refrigerator cooling system was analyzed through the change of freezing temperature and power consumption. The results indicate that ambient temperature can affect the heat load of the refrigerating system and the matching of two temperature，for the purpose of matching control of refrigerator temperature and energy-saving can be realized through the change of gas volume of inverter compressor and target control temperature when in different ambient temperature.
