Water heaters are one of the indispensable parts of every family. When we choose water heaters, many families like to choose solar water heaters. When we choose, the bathroom does not know how to decorate many people are troubled. So everyone knows what needs to be paid attention to when installing solar water heaters? Today, Xiaobian will take a look at the solar water heater installation method and installation precautions!
Solar water heater installation method:
1. Check the product parts: Before installation, check the specifications of the water heater according to the design requirements, check whether the accessories are complete, and clean and mark the site. The solar water heater support should be prepared according to the design details, which is generally assembled on the spot of the finished product. The installation of the support base plate should meet the design requirements.
2, the installation of flat collector: flat collectors are used in a wide range of applications, collector glass installation should be water or a frame connection, the optimal inclination of the collector installation should be determined according to the season of use and local latitude. In the northern hemisphere, the best orientation of the collector is towards the south.
3. Installation of solar water tank: When installing the solar water tank, the water supply should be led to the bottom of the water tank, and the water tank or the funnel can be equipped with water. The take-over height is generally 50-100 mm lower than the upper circulation pipe inlet. The bottom pipe of the water tank is connected in parallel with the upper hot water pipe, and the upper circulation pipe is connected to the upper part of the water tank, generally about 200 mm lower than the top of the water tank, and the lower circulation pipe is connected from the lower part of the water tank.
4. Installation of connecting pipeline: In order to reduce the loss of circulating water head, the length of the upper and lower circulating pipelines should be shortened as much as possible and the number of elbows should be reduced. The elbows and downstream tees with more than 4 times radius of curvature and smooth inner wall should be used. It is not advisable to install a valve on the pipeline. When several collectors are installed, the collectors can be connected in parallel, in series or mixed, but the circulation flow should be evenly distributed. To prevent short circuit and stagnation, the circulation pipelines should be installed symmetrically, and the circulation head loss of each circuit should be flat.
Balance.
5. Commissioning operation: Before the solar water heater is installed and ready to be delivered, it should be commissioned and run. The system should be filled with water to eliminate the air. Then check the circulation pipeline for air resistance and stagnation. Check the operation of the pump with mechanical circulation. Whether the temperature rise of each circuit is balanced, and record the temperature rise.
Solar water heater installation precautions:
1. In winter, due to the low temperature, the solar energy is short. When installing the solar water heater, the outdoor pipeline and the exhaust overflow pipe are first put on the rubber and plastic insulation pipe, and then the thick polystyrene material is used for heat preservation to avoid water. Freezing, which causes the hot and cold water to go up and down, and may even damage the solar water heater tank.
2. If the pipeline does not go to the flue, go outside the building, because the pipeline is fixed on the side wall of the building to ensure safety and beauty. When connecting the pipe fittings at the water corner of the hot solar water heater, clamp the water with a wrench or pipe wrench. Mouth, then link other fittings.
3, pay attention to the weather, especially the temperature situation, in the case of not too low temperature, after the night of water, such as there is hot water in the water tank, because of the immediate water; if the temperature is relatively low, the next day should be water If the weather is not good the next day, rainy days or rain and snow, according to the situation of domestic water, water, try not to fill the water.
4. When the temperature is below zero, be sure to turn on the hot water tap of the solar water heater to ensure the smooth flow of solar energy in the form of dripping water, so as not to freeze the water pipe.
When we choose a solar water heater, we need to know how to install it. The above is the installation method and installation precautions for solar water heaters introduced by Xiaobian today. I want to know more information, please continue to pay attention to the decoration home.
