A good way to heat food in the dormitory, the dormitory is very hot, ask for a way to cool down.

You can choose self-heating food, or use a thermos cup or thermos bucket, which is more convenient and trouble-free.

Generally, it is a container made of double-layer plastic or stainless steel with a vacuum layer or thermal insulation layer, with a lid on the top and a tight seal, and the vacuum layer or thermal insulation layer can delay the heat dissipation of the meals installed inside, so as to achieve the purpose of heat preservation. The insulated lunch box is developed from a thermos flask, and the principle of thermal insulation is the same as that of a thermos flask. There are three ways in which heat can be propagated:

Radiation, convection, and transfer. The silver liner in the insulated barrel can reflect the radiation of heat, and the vacuum layer or insulation layer of the cup can block the transfer of heat.

Modern insulated lunch boxes apply high-tech vacuum technology and will be double-layered high-quality 304 stainless steel.

Internal vacuum treatment can effectively block the heat source and achieve the effect of heat preservation. The design is more humane, usually designed as three or four layers, and the lunch box and soup box that need a higher temperature are placed under the insulated barrel, and then the middle is covered with a heat insulation board, and then the food box is placed on top, which can not only bring you the best thermal insulation effect, but also make your food and drinks longer and fresher.

The principle of the thermos cup is the same as that of the thermos bucket, and you can refer to the method that the thermos cup cannot be opened

When you pour hot water into a cup, the air and water in it are all there.

They swelled, and after a while, they cooled and contracted, so that there was a pressure difference between the inside and outside of the cup, so it could not be unscrewed. The solution is to overcome this pressure difference.

Put food in a plastic bag and put it in hot water, or heat food with your body (even if you don't have a microwave).

Buy a plugged-in fan, and turn it on when it's too hot in the bedroom, but you can't do it when the power is off. You can also buy a small electric fan that can be plugged into the power bank, although the wind is not strong, but it can still be slightly cooler after the power is off at night. It is recommended to buy one of both, after all, the school will not provide electricity to the dormitory overnight every day.

When the power is about to be cut off, wet the mop, don't wring it too dry, mop the bedroom again, the moisture is on the floor, and the heat of the floor is sucked away while the water evaporates, and the temperature in the bedroom is reduced at the same time, but this method can only live in the place for a short time, once the water is evaporated, it still returns to the original state.

There is no need to do this in the morning, mainly after noon, the hottest time of the day, the temperature gradually rises, and the temperature in the bedroom is also driven, then you can use a bucket or basin to fill more than half of the water in the bedroom, we all know that the specific heat of the water is very large, the water temperature is lower than the temperature of the indoor air, it will suck away the temperature of the air higher than the water, so as to achieve cooling, and this method can also be used before going to bed at night.

On a hot day, you may not necessarily be taking a bath every day, but in order to be able to sleep peacefully at night, then please take a shower before going to bed, cold water is the best, if you really can't stand the cold water, take warm water, don't wash too hot water, that will not work. After taking a bath, the water on the surface of the body evaporates, so the heat from the body is absorbed, which lowers the body temperature. However, this cooling will not last long.

This method is natural and environmentally friendly, as long as the roommate is in the dormitory, open the doors and windows and everything, and keep the dormitory ventilated, otherwise no matter how cool it is outside, it will not close the dormitory. The dormitory is always ventilated, and convection must be formed in order for the air in the dormitory to be exchanged, so you can't just open one window, and another advantage of ventilation is that it can prevent the spread of disease.

If your bedroom is sunny and there will be sunlight at a certain point in time, then you can happen to install a curtain to block the sunlight from coming in, so as to prevent the temperature from getting too high, it is recommended to buy green curtains, because this kind of curtain can play a psychological role in cooling, green is not as high-key and bright as red. Give a comfort.

Buy some small potted plants and put them in the bedroom, which can not only beautify the bedroom environment, look comfortable, but also purify the air, and, under the irradiation of the sun, it will have transpiration, and then increase the humidity of the air, which will reduce the indoor temperature, and the potted plants are not expensive, this thing is easy to do.
