On a hot dry day, the amount of water vapour present in air is less. Thus, water present inside the desert cooler evaporates more, thereby cooling the surroundings more. That is why a desert cooler cools better on a hot dry day.
Answer:
▶Desert coolers transfer the heat energy from circulating air to water. Water evaporates resulting in the cooling of the surrounding air and this air is circulated. On a hot dry day, the humidity will be low and the temperature will be high. Therefore desert cooler cools better on a hot dry day.
