1.
Since the increase in room temperature due to the summer heat decrease in room temperature due to winter chill and the effect of a cooler are in the same direction, negative feedback facilitates inhibits the cooler (function).
2.
Since the increase in room temperature due to the summer heat decrease in room temperature due to the winter chill and the effect of a cooler are in the opposite direction, negative feedback facilitates inhibits the cooler (function).
3.
When room temperature is increased decreased , negative feedback facilitates cooler (function).
4.
When room temperature is increased decreased , negative feedback inhibits cooler (function).
