Can the building use solar hot water bottles for bathing?

No. Solar hot water bottles should be placed on the roof of a rural bungalow and should be placed in a place with the best light in the house, otherwise the heating effect will be affected and they can only be used during dog days. in summer, it is basically ineffective in winter and is only suitable for rural bungalows. The solar hot water bottle is made of polymer nylon plastic, added with anti-aging agents, ultraviolet heat absorbers and other special heat-absorbing materials, and a double-layer composite surface of a collection device of heat.

About the scientific principles of “solar hot water bottles”

Installing solar hot water bottles is very simple, you just need to place the water bag where it should be used and fill it with water (not recommended). Using the automatic water adding device will make the water in the water bag cooler), it doesit be in a position where the sun can reach the maximum.

The principle of the solar hot water bottle:

1. Use thermal radiation to transfer solar energy to the hot water bottle.

2. In order to improve the ability to absorb sunlight, hot water bottles are usually made from black materials.

3. When using hot water indoors, you can use the relationship between flow and pressure to adjust the hot and cold degree of the water.

I am a practitioner of solar water heaters. I don't know if the solar hot water bottle you mentioned is the black plastic bag commonly used in Shandong and other areas for rooftop bathing. If so, it's simple: it is a closed black plastic bag to which two pipes are connected, one for the water inlet and the other for the return signal pipe. 'water. When using, first place the plastic bagonly on the roof with direct sunlight and use the tap water pipe to fill the plastic bag with water through the upper and lower water pipes. When the water is full, water will flow out of the signal pipe. , and the tap water will be turned off. As the black plastic bag absorbs heat easily, it naturally heats the water inside and can therefore be washed in the evening.

This thing is relatively cheap and can usually be bought for a few dozen yuan. However, since it cannot retain heat, it can only be used in summer, and due to the aging of rubber, it is used. Generally can only be used for one year.
