Pressurized Solar Water Heater
Pressurized solar water heater utilizes high absorption rate and low projection rate coating of vacuum tube, and it changes solar radiation into heat energy. Meanwhile, the copper pipe inside the vacuum tube could quickly transfer the heat into the water tank. Eventually it leads to gradually increase the water temperature in the whole water tank. Vacuum tube could work as long as it has sun radiation.
Pressurized solar water heater characteristics:
Heat pipe has the functions of? one-way heat transfer, small thermal capacity, low start-up temperature.
Heat pipe could resist low temperature, even in the low temperature condition it will not be broken.
For inner tank, we adopt high frequent melting technology. Water heater¡¯s rated pressure is 0.6*** and 0.4***.
It can directly connect with tap water system; pressurized and automatic operation.
No watr in the heat pipe. It eliminates the low heat efficiency problem caused by fur. And, it also could avoids the damage problem caused by cold weather. Even if in the cold weather, the whole system could also work smoothly.
Principle of Pressurized Solar Water Heater:
The pressurized water tank has no exhaust hole, therefore, it must bear the pressure came from tap water and hot water. When use, the hot water comes out because of water pressure. Vacuum tube absorbs solar energy, and conductive copper pipe transfers the heat into the pressurized water tank. In this case, the water inside the tank becomes hot. No water in the heat pipe makes the whole system could bear pressure.
Advantages of Pressurized Solar Water Heater:
The system is pressurized.
Keep a constant temperature of water in the tank.
Avoid the problem came from water level controller malfunction which could cause water flow out.
