How Does it Work?
The heart of an evaporative cooling system is the pad where the water evaporates and the air passing through the pads is cooled. A special water distribution system spreads water over the surface of the pad, ensuring a uniform supply of water to keep the entire air contact surface thoroughly wetted. Fans create a negative pressure, causing air to be drawn through the pads. Evaporation results from contact between air and water. A control system operates the water pump and the fan distributes the cool air.
The relative humidity is lowest in the afternoon when the temperature is at its highest. And the lower the humidity, the better the evaporative cooling effect. In other words, the cooling effect is best when you need it the most.

The Thar Desert has low vegetation cover, so the ground heats up quickly during the day and cools rapidly at night. During the day, the desert receives intense sunlight and absorbs heat, raising temperatures. At night, without the sun's heat, the desert rapidly loses warmth, leading to cooler temperatures.
The Simpson Desert is known to have extreme temperatures, with hot summers reaching over 40°C (104°F) and cooler winter nights dropping below freezing. Overall, the desert is more commonly associated with its intense heat during the day.
Rodents in the desert typically feed during the cooler hours of the day, such as early morning or late evening. This is to avoid extreme heat and predators that are more active during the hotter parts of the day.
The desert will heat up faster than a lake. The sand particles have greater thermal conductivity and hence will take up heat faster than water molecules which do not take up heat as easily. It is also the reason why it is cooler at the sea side.
During the day, pavement absorbs and retains heat from the sun, causing it to be much warmer compared to the air temperature. At night, the pavement begins to lose that stored heat and cools down, often becoming cooler than the air temperature. This temperature difference can have implications for things like road maintenance, tire wear, and the urban heat island effect.
In a desert cooler, the water inside it is made to evaporate. This leads to absorption of energy from the surroundings, thereby cooling the surroundings. Again, we know that evaporation depends on the amount of water vapour present in air (humidity). If the amount of water vapour present in air is less, then evaporation is more. 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

hummm i dont really know i think it is food
It makes you sweat more and cools your blood
A desert usually has little cloud cover and high humidity that would hold in day time heating. Therefore, the desert cools quite quickly when the sun sets.
Many desert animals are not abroad during the heat of the day and only emerge at night when it is cooler.
A desert fox, and most all desert animals, sleep during the day, and hunt at night, because it is cooler at night.
Sunshine during the day heats the surface of the desert. That then heats the air above it. Since the desert has few clouds of high humidity to hold this heat after the sun sets, the heat radiates back into space and the desert cools down quickly.

A desert.. I think so because most of the animals are sleeping during the day when it's hot out, and they come out at night when it's much cooler. But i am pretty sure that there are some dangerous animals in a desert.

All owls have night vision. Since the desert can get so hot, most animals, including owls, come out at evening or night to avoid the heat of day. Since they're active at night, it's good to have nocturnal vision. Some desert owls are elf owls, pygmy owls, burrowing owls, great horned owls. It allows them to hunt when it is cooler.
