Beschreibung
Zusammenfassung:	The invention discloses a display cabinet control method and device and a display cabinet, and the method comprises the steps: detecting the temperature parameters of the display cabinet in each refrigeration cycle; wherein the temperature parameters at least comprise the difference value of the cabinet temperature and the return air temperature and the saturated evaporation temperature; calculating a refrigeration attenuation coefficient of the display cabinet according to the temperature parameter; whether the display cabinet meets the defrosting requirement or not is judged according to the refrigeration attenuation coefficient; and when the display cabinet meets the defrosting requirement, the display cabinet is controlled to enter a defrosting mode. The problem that in the prior art, defrosting control of the display cabinet is not intelligent enough, and consequently the cabinet temperature is abnormal is solved, the stability of the cabinet temperature can be maintained, and the defrosting intelligence
