From chart in description part, we find that opening the door will cause the increasing of humidity. And fridge starts dehumidification as soon as the door is closed. However, when fridge starts refrigeration depends on its temperature threshold. So dehumidification and refrigeration are independent from each other. Besides, the value of pressure is irrelevant to both dehumidification and refrigeration. However, refrigeration will cause a subtle change to pressure.
From the table in description part, we find that for the same fridge, it is more efficient when opening the door for shorter time. However, we don't think it is a reasonable factor since the temperature in fridge will continue increases after closing door without refrigeration when temperature is lower than threshold.
When comparing the two fridges, we find that fridge 2 is more efficient. From the charts, we find that the threshold of fridge 1 is higher than fridge 2. So we can have an approximate conclusion that the refrigeration threshold of fridge may influence refrigeration efficiency. We cannot verify it since the other parameters of refrigeration is different.
