1. Installation of solar water heaters
The installation should take into account factors such as solid fixing and structural safety, wind protection, lightning protection and roof drainage.
Fixed on the waterproof layer of the roof to prevent damage to the waterproof layer and cause roof leaks.
Specific method: pour concrete pillars directly on the roof and embed expansion bolts on the pillars. Location of piers and abutments: Piles and abutments must be located above the load-bearing wall. Direct pouring onto the ground is strictly prohibited (it is easy to overload, causing the floor to deform and leak). The size of the pier is determined based on local wind load and wind resistance calculations. In order to increase stability, several households are advised to build a joint pier together. LeaveDrainage holes on the pillars to ensure smooth drainage on the roof.
Safety measures for lightning protection
Solar water heaters installed on the roof generally exceed the height of the roof parapet, so the originally designed roof lightning protection system was ineffective against solar water heaters. In buildings where solar water heaters are retrofitted, lightning protection measures should be considered.
For buildings where the installation of solar energy is uniformly considered during the design phase, measures such as fixing and lightning protection must be uniformly taken into account during design.
2. Installation of an electric water heater
Installation of an electric water heater involves the choice of the installation location and the measurements offixation. , cables and sockets, leak-proof design, etc.
Installation location: The installation location of electric water heaters is generally in the bathroom. For the sake of beauty in the bathroom, the electric water heater is usually installed in the suspended ceiling, but this approach will make the suspended ceiling hollow, airy and visible. It is strictly prohibited to install in a closed ceiling.
Fixing measures: The electric water heater must be fixed to the wall or floor. When attached to the wall of a supporting structure, the bolts may be directly recessed or the expansion bolts may be directly driven in; when attached to the 120 thick brick partition wall, the bolts shall be embedded in the concrete embedded block wall; when the bathroom wall is made of other materials When separating a wall, you should choose to fix thefloor slab, embedding bolts into the floor slab or embedding iron parts, then welding the bolts to the iron parts.
Cables, sockets and leak-proof design: When designing a new residential electrical distribution, the electrical load of electric water heaters or air conditioners is usually taken into account account. Consider the ground wire when designing cable routing. All three-hole outlets have reliable ground wires connected to the ground. Use leak-proof sockets for outlets, and reserve a three-hole outlet where the electric water heater is installed in the bathroom.
In order to prevent residents from connecting ground wires to water pipes, causing metal pipes to leak throughout the building, equipotentials should be installed in rooms equipped with electric water heaters such as toilets, bathrooms and kitchenss. Connect the system to prevent leaks.
3. Pipe installation
Pipe installation of solar water heaters and electric water heaters is an important part of the photovoltaic system. complementary hot water system. Formed on May 1st. including pipe materialsThree aspects: quality selection, pipeline laying and pipeline insulation.
Pipe material selection: It is recommended to use aluminum-plastic composite pipes for solar water heater pipes. It is not suitable to use flexible pipes and PP-R pipes because these pipes are very deformed and difficult to fix.
Pipe laying: Special wall pipes or pipe wells should be used for laying water pipes up and down solar water heaters. Pipe fixing clips should be reserved in caves or pipe wells for fixinger the pipes.
Pipe insulation: Hot water flows from the roof into the room and must travel a certain distance. The longer the pipe, the greater the heat loss along the way. The pipes must therefore be insulated. For pipes covered with cavities, a layer of insulating material should be wrapped over the pipe. For the special pipe well laying method, insulating materials, such as expanded perlite, can be filled into the pipe wells.
It is best if the supporting pipes for solar water heaters are uniformly provided by the manufacturer. The pipes are manufactured directly into insulated pipes, which increases the flexibility and adaptability of the installation and reduces the workload of installing insulation on site.
1. Before installation, first choose the installation location, make sure the installation location of the water heateru solar is not a place of residential activity and that the installation site meets the product requirements. For example, the wall for suspended installation should be thick > 10 cm solid wall, it is better to install a stronger support when installing more than 80 liters capacity;
< /p>Since the water tank and the collector are separate, the collector can be "embedded" in sunny places such as balconies and walls, and the water tank can be placed in kitchen, bathroom, etc. as needed from upstream and downstream. the water is inside, the water heater is no longer afraid of severe cold in winter and is windproof and antifreeze, high thermal efficiency and many other advantages, which greatly reduces the use restrictions solar water heaters in buildings and makes them comfortable. to use. In appearance, the collector is organically integrated into the buildingnt. While neat and beautiful, it avoids the dangerous factors caused by installing traditional solar water heaters on the roof of the building. And because the water tank is very close to the water outlet. , it saves water while saving water and greatly improves the utilization rate of hot water.
2. If there is a wall bracket or extending part outside the wall and it faces the sun, the sensor can be fixed on it and reinforced with a stainless steel tripod. , and Reinforce with extended expansion nails, the length should exceed the thickness of the wall
3. If there is no wall bracket, you can use stainless steel brackets to fix the wall; collector on sunny wall On wall;
4. If you encounter existing structural obstacles in a building, for example, some high-rise walls have layers of insulation on the exterior, and the serviceproperty management does not allow installation, and not in all locations. For example, if there is no insulation layer under the balcony, a beautiful and practical location can be determined for the owner to install the balcony wall-mounted solar power
;5. You can refer to the air conditioning installation method
6. If it cannot be installed, you can choose an external one. solar water heater;
7. The final step is finding professionals from the manufacturer to handle the construction.
