Full analysis of Frequently Asked Questions
Solar water heaters are usually the collector, insulated storage tanks, connecting pipes, brackets and control system.
By using the classification, can be divided into seasonal water heaters, water heaters, as well as year-round all-weather solar water heaters, auxiliary heat source. According to the principle and structure of the collector can be divided into flat-water heater and vacuum tube water heater. By the working fluid flow in different ways, generally divided into nausea drying, recycling-based and DC-type three.
Solar water heater solar collector is to receive and convert solar energy to heat the core components and key technologies, the cost of solar water heaters account for about one-half the total cost of about. Full glass according to the different media can be divided into hot all-glass vacuum tube and heat pipe vacuum tube collector (glass and metal combination) collectors two. Their main components are the key to a vacuum tube or heat pipe vacuum tube.
Currently the most popular all-glass vacuum tube as an elongated thermos bottle, the two pipe length of 1.2 meters or 1.5 meters in diameter, 37 mm and 47 mm concentric glass tubes formed by the vacuum. All-glass vacuum tube materials, processes and simple structure, good reliability, with a great application prospects.
Solar hot water heater tank is the storage device, its structure, capacity, thermal insulation and materials will directly affect the water heater\\ s performance and operation of the quality.
Tank type, divided by the square shape, flat box-type, cylindrical, spherical tank; placement method divided by vertical and horizontal; divided by atmospheric pressure state\\ s open-closed water tank and pressure Water Tank; according to whether there is an auxiliary heat source can be divided into ordinary water tank and water tank with auxiliary heat source; by way of heat exchanger can be divided into direct and secondary heat exchanger tank indirect heat exchange tank.
Production quality of the material tank, the tank pressure, temperature, seepage and water quality greatly. Domestic water tanks commonly used materials treated with preservatives or enamel steel, galvanized steel, rust-proof aluminum, drugs, plastic or glass steel, stainless steel panels. Hot water tank features include heat characteristics, heat characteristics, thermal insulation properties. Exothermic feature is the hope that the hot water tank can be put out, easy to use. Domestic water tank can be vertical, into the cold water from the lower part of the roof, hot water from the upper outflow. Heating characteristics of most of the water tank is heated up top, then lower the heat up slowly. Insulation characteristics refer to the speed of decline in water temperature, and sealing of water tanks, insulation materials, temperature, size and other related water capacity.
With the recent sales surge water heater, problems follow. Now to tell you about solar water heaters common solution to the problem.
First, there is no water around, how to use solar water heater?
In the absence of water areas to the use of solar water heaters, and can use the pump in Sheung Shui, an additional an additional auxiliary tanks and solar water heater the same height, to store cold water, so that against the cold water bath.
Second, solar water heaters in the course of what issues should pay attention to?
1 Note Sheung Shui time.
2 according to weather conditions, the decision on the water to ensure proper water temperature when bathing.
3 regularly check water heater pipes, vents and other components are working properly.
4 serious air pollution or wind, dry areas regularly wash vacuum.
5 water heater installation. Do not move non-professionals, loading and unloading the machine, to avoid damage to critical components.
Third, how to choose water heater according to family size?
Under normal circumstances, each one bath of hot water to be 20-40kg, 6.5kg each tube can be heated in water, according to family size and can be used to estimate the required bathing water heater capacity.
Fourth, how to determine the solar water heater full of water?
Solar water heaters have the general safety overflow pipe, according to the overflow pipe to determine whether the drainage water over the state, the other can be equipped with water level controller, water full automatic alarm, according to police discrimination.
Five tanks broken up, deflated may be what causes it?
May be due to vent blockage, when the water into or discharged, the internal air can not be discharged or to be added, the formation of internal and external pressure difference, resulting in breaking up or deflated tank.
Sixth, the size of the tank and vacuum tube count of the relationship?
General design is based on bathing water heater hot water temperature required for the design, the design temperature record Stewart solar water heater range is 400 ? ~ 900 ?, the water heating tubes each approximately 6.5kg.
Seven, Sheung Shui, should pay attention to what the problem?
As the vacuum drying in the air when the tube temperature can reach 2500 ? or so, so water in the tank or the first time before sunrise or in the Sheung Shui to be a half hour after sunset.
Eight, how to determine the pros and cons of solar water heater?
Solar thermal solar water heater is a kind of part of the entire water heater including collector, heat storage part, stand part. Determine the merits of the most important part of the collector is the collector component based on the absorption rate and the divergence rate, which is the relevant materials and production process.
