内置盘管式太阳能热水器

常州美迪克能源科技有限公司改善传统太阳能能存在的热水量有限、出水小，需等待加热、水质越用越差等问题，首度生产的“二次换热”技术获得成功，将高温高效与热水快速循环完美结合起来，达到了太阳能行业热利用的新高峰。
　　在不承压的水箱中设置了换热盘管，水箱中的水可以与集热器进行自然循环，洗浴用水则通过盘管与水箱中的热水进行热量交换，可以有压喷淋。铜质、盘管虽增加了成本，但其换热能力大大增加了，为保证连续的洗浴需要，将由水箱温度和盘管换热面积所决定。
系统原理：
　　水箱中的水只起到吸热储热和放热作用，储热水箱中的水容量保持恒定，使用热水是通过储热水箱太阳能热水中的盘管冷水进入，冷水通过盘管吸收储热水箱太阳能热水中的能量使温度升高，因盘管设计的固有性能，盘管内的出水温度接近水箱中太阳能热水温度（温差＜＝3℃），这样，有压力的自来水不断进入盘管吸收太阳能热水能量而使温度升高后放出使用。储热水箱中水容量不变但水温不断降低至与盘管内的水温无传热价值时止。

内置盘管式六大优势：

1.  
   1. 直接使用的热水和加温的水封闭隔离，确保使用新鲜“活”水
   2. 内置50米长优质紫铜盘管，水质更洁净，水管寿命超过50年
   3. 冷、热水温随心调节，杜绝水温忽冷忽热无法恒定的现象
   4. 直接来自供水网的水压使沐浴、喷淋更畅快
   5. 储水箱内无需每天上水，避免了烦琐的操作
   6. 使用时水箱内水容量保持不变，避免储热水箱忘记上水时的空晒现象

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 0.6Mpa and 0.4Mpa.
It can directly connect with tap water system; pressurized and automatic operation.

1. 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 es hot. No water in the heat pipe makes the whole system could bear pressure.
Advantages of Pressurized Solar Water Heater:

1. The system is pressurized.

2. Keep a constant temperature of water in the tank.

3. Avoid the problem came from water level controller malfunction which could cause water flow out. 

4. Solve the water level control switch failures, resulting in "Shuimanjinshan."
