The water coming out of the solar water heater is always hot and cold, which is caused by the valve of the upper water pipe not being closed well. If this happens, you can install a thermostatic valve between the hot water. the water pipe and the cold water pipe. The specific operation steps are as follows:
1. Prepare a constant temperature valve. As shown below:
2. Connect the plastic pipe to the cold water pipe.
3. Connect C on the thermostatic valve to the cold water pipe.
4. Connect the plastic pipe to the hot water pipe.
5. Connect H on the thermostatic valve to the hot water pipe, and the operation is completed.
After a tiring day at work, we are very happy to take a hot shower at home. This requires the bathroom of the house to be equipped with a water heater, and solar water heaters are the best. most popular inmany families. The first choice, because it is very convenient to use and saves electricity, but if there is a problem during use, everyone does not know what to do. Actually, if you know the structure diagram and how it works. principle of the solar water heater, you will know where the problem is. Today's editor leads you to learn the following relevant knowledge.
1. Description of the structural diagram of the solar water heater
1. The working process is as follows: the compressor compresses the returning low-pressure refrigerant and transforms it into a high-temperature, high-temperature fluid. pressurized gas that circulates through the pipes. The high temperature and high pressure gas refrigerant circulates through the copper tube wrapped around the outside of the water tank. The heat is conducted into the water tank through the copper tube for heat exchange. THEgaseous refrigerant becomes liquid under the continuous action of pressure and enters the evaporator after passing through the expansion valve, because the pressure of the evaporator suddenly decreases, the liquid refrigerant quickly evaporates into a gaseous state and absorbs a large amount heat. At the same time, under the action of the fan, a large amount of air flows through the outer surface of the evaporator. The energy in the air is absorbed by the evaporator and the air temperature drops quickly, turning into cold air. unloaded in the kitchen.
2. Then the refrigerant, which has absorbed a certain amount of energy, returns to the compressor and enters the next cycle.
3. From the above working principle, it can be seen that the working principle of household multifunctional water heaters is somewhat similar to that of air conditioners. It uses the inverse Carnot principle to absorb a largelow consumption quantity. -Thermal energy from the temperature in the air and compress it. The compression of the machine turns into high temperature thermal energy, which is transferred to the water tank to heat the water. The whole process is an energy transfer process (from air to water), not an energy conversion process. There is no heating of hot water by electric heating elements, nor combustion of flammable gas to heat hot water. If you want to use a good solar water heater, not only is the purchasing process very important, but the installation process cannot be ignored. Apart from choosing a trustworthy solar water heater brand, the most important thing is the installation of the solar water heater. water heater, because the purchased solar water heater is just a piece of equipment. Semi-finished products, solar water heater installation and after-sales service are also provided.ent very important links.
2. Solar Energy Installation Process
1. Prepare construction tools. For example: screwdriver, wrench, electric drill, etc.
2. Open the water heater package and check the accessories according to the packing list. Is it complete? 1) The vacuum tube count is complete and intact; 2) Electric heating is intact; 3) The water tank body is dented; 4) Support accessories are complete;
3. Select the installation location. Generally, we choose it on the roof. The orientation is north-south, 5 to 10 degrees west of south to ensure there are no obstructions. The number of pipes entering the house should also be reduced to increase the number of sunlight hours.
4. Assemble the stand. When installing, you need to assemble the front and rear parts according to the instructions, then use a wrench to tighten the screws untiluntil there is no more play. Then support the front and rear pieces laterally for structural reinforcement.
5. After installing the water tank and suction pipe, tighten the screws for inspection. Typically, cement pillars, expansion bolts or wire cable fixing brackets are used. Of course, you need to choose the best fixing method based on your roof conditions. Wire rope fixing method: Place the wire rope or large steel bars on the left and right frames of the front bracket and the left and right U-rings of the bucket bracket, and tighten them with nuts. Stretch the four connected metal cables or. steel bars towards the four corners of the water heater, and place them on the parapet or other. Select a suitable location, drill holes and press the expansion hook, and firmly connect the wire rope or barof steel to the corresponding U-shaped ring of the expansion hook.
6. Electric heating installation. First open the dustproof insulating cover of the electric heating port, loosen the screws inside, then open the plug at the bottom, check the built-in rubber sealing ring to see if it is tight, then place the integrated electrical connector. heating rod and restore it once it is tightened.
7. First place the water tank on the assembled bucket bracket, connect the water tank and the bucket bracket with bolts, and tighten the connection nuts between the shelf and the bucket bracket to maintain the distance between the two. ends of the water tank and the left and right ends of the bracket. Likewise, the vacuum pipeline is parallel to the plane of the front bracket, then put the silicone sealing ring into the flange hole of the inner body and lay it flat.
After studyingits structure diagram and principles, do you think it is very simple? The bottom line is that the compressor compresses the returning low-pressure refrigerant and turns it into high-temperature, high-pressure gas that flows through the pipeline. Gas at high temperature and high pressure. The gaseous refrigerant circulates through the copper tube wrapped around the outside of the water tank, and the heat is conducted into the water tank through the copper tube for heat exchange.
