Comparison of the results of different collection time intervals at the intermediate temperature measurement points in the cold storage.

Collection interval	Average value of all measuring points in 5 minutes (°C)	Average value of all measuring points in 10 minutes (°C)	Deviation (°C)
Working temperature of cold storage	−17.36	−17.37	0.01
Highest temperature of cold storage	−14.87	−14.89	0.02
Lowest temperature of cold storage	−18.53	−18.47	−0.06
