Solar water heater There are many options for installing water pipes, such as PPR water pipes, copper pipes, copper-plastic pipes (aluminum-plastic pipes), PVC pipes, iron pipes, etc. In fact, considering various factors, PPR water pipes are quite ideal. The reason is also very simple. Firstly, the quality of good PPR water pipes is very reliable, which is quite comparable to that of copper pipes. Secondly, the price is more acceptable and much lower than copper pipes; that it is healthy, without any rust or patina. Note that the water pipe must be 6 points. PPR water pipes are divided into cold water pipes and hot water pipes. The key is the thickness of the pipe wall. It is recommended that everyone use hot water pipes for drainage at home. the price is not much more expensive. VSConsidering that solar water pipes must be antifreeze, meaning they cannot freeze and crack under normal circumstances, there are only three types of pipes on the market: true PEX reticulated pipes, PERT pipes and PB pipes. Currently, most of the market uses PEX as solar water pipes because it is frost resistant and relatively cheap. However, over the past couple of years, many manufacturers have significantly reduced their degree of crosslinking in order to compete on price. market, thereby reducing costs. However, at the same time, its antifreeze performance is also significantly reduced. If you use it, it is recommended not to choose one that costs less than 140 yuan. PERT is better than PEX, but the cost is relatively higher, so there are few in the market for solar; PB pipes must be considereds like the best anti-freeze pipes on the market. high-end floor heating projects, of course, its cost is higher, and it cannot be promoted in the solar power industry at present. Therefore, it is recommended to choose higher quality PEX cross-linked pipes, as long as you are not trying to be cheap. PPR cannot be used as solar water supply and drainage pipes. It can freeze and crack in one winter in the north (it can be used in the south). We used the best ones, but they don't work. Aluminum-plastic pipes are no good either. Foshan Rifeng and Jinde used them for only four to five years in the north and south of the Yellow River, and only two or three years in the northeast. But indoors, for aesthetic reasons and high indoor temperatures, PPR or aluminum-plastic pipes can be used.
Howt make solar water heater
Aluminum-plastic pipes are mainly used. Aluminum-plastic pipes are easier to install, have a certain elasticity and can be bent, and most importantly. The thing is, they're rolled up. If you use PPR pipes, it can be installed indoors. If installed outside, how do you connect it?
Solar water heater is a device that converts solar energy into thermal energy, heating water from low temperature to high temperature to meet people's use of hot water in life and production. Solar water heaters are divided into vacuum tube solar water heaters and flat panel solar water heaters based on their structural shapes. Evacuated tube solar water heaters are mainly used, accounting for 95% of the domestic market share. Domestic evacuated tube solar water heaters areconsisting of heat collecting tubes, water storage tanks, brackets and other related parts. The conversion of solar energy into thermal energy mainly relies on vacuum heat collecting tubes which use the principle of hot water floating. and cold water flows to cause microcirculation in the water.
1. To prepare the materials, you must first prepare the following materials: solar panels, PVC.Pipes, tees, elbows, internal joints, glue, insulating pipes, paint, electronic thermometers, old iron sheets, plastic foams, old sponges, etc.
2. First find solid, good quality wood and simply make a 2.1X1.2m frame. Then transform the T-pipe into a hot exhaust pipe of the same type as the water heater device. Then pour foam over the frame and paint the foam and the old iron sheet black.
3. Connect the compound shelfe of solar panels to the thermal tube. Note that the pipe must be installed with an insulating tube. If you have an electronic thermometer, you can install an electronic thermometer for easier detection. of the water temperature.
4. Install the vertical post behind the support and cardboard. The height and inclination of this vertical pole can be adjusted as desired. Then the glass tube is filled with water and the glass tube is first sealed and then placed on the rack. Then adjust the pole, observe the direct angle of the sun and adjust the pole to the corresponding height. The larger the area exposed to the sun, the better.
5. When adjusting the concave arc of the pole, you should do it on the roof of a building exposed to the sun or in a high place. The reflection of the sun focuses on the glass tube. better effect. Then simply attach the bracket.
6. After a while, the solar water heater willIt house can use the principle of cold water flowing and hot water floating to check the water temperature. Then wait a while, then check the amount of hot water obtained. You can also fill the homemade solar water heater with an appropriate amount of water according to the weather of the day and connect the pipe from the water outlet to the place where hot water is needed.
