The working principle of solar air conditioner

There is a heat absorbing device in the solar collection conversion, which can switch the energy of light, heat, radiation of the environment into energy, which can assist compressor in doing the job of cooling and heating. More over, the energy absorbed in the day time can be stored in the heat absorbing device, ensure the air conditioner to work normally all day.

The solar energy air conditioners make use of the principle of light-sense point arouse and dispersing Photosynthetic, and the principle of reversible of chemistry energy, they fully adjust to absorb and store solar energy by the Binary mixture refrigerant of Solar collector layer, Then through the cold, hot assistants of the solar energy, they regulate the cold and hot of the solar AC, Then they can reach the best quality of saving electric according to the requirements.

The so-called solar energy refrigeration means providing the absorption type of refrigerator with the heat carrier water which the generator needs. The higher the temperature of water the higher the energy efficiency ratio (COP), and the effect of refrigeration is also higher. For example, if heat carrier water’s temperature is about 60℃, then the COP of refrigerator would be approximately 0-40; If heat carrier water’s temperature is about 90℃, then the COP of refrigerator would be approximately 0-70; If heat carrier water’s temperature is about 120℃, then COP of refrigerator may reach 110℃ or above.

Solar air conditioner's application method

Our solar air conditioner are widely used in the hotel, the market, the bath center, the villa, the office, the workshop, the people's rooms, aquatic breeding farm, fowl feeding farm and so on. They are of high quality with reasonable price, our solar air conditioners are the modern, ideal equipment for the family, the work and business places and so on.

1. The installation does not limited by the location, it can be installed in any place since the solar panel is not large.Furthermore,it is not required to face to the sun.
 
2. They wouldn't be effected by the weather, no matter in the cloudy, rainy day or in the sunshine day, or in the evening the effect is of the same,
it absorbs  heat and radiation. Both of electricity and the energy absorbed in the day time stored in the heat absorbing device can ensure the air conditioner to work normally. More over, the energy absorbed in the environment can be consumed and renewed continuously.In comparing with the normal conditioners,ours can save 50% of the power;

3. Compared to normal air conditioner, the fluctuation of temperature is slightly slower,
it needs serval miniutes to reach the appointed temperature;
 
And the longer you use it, the less electricity can be consumed comparing with normal conditioners.

4.
The refrigeration of solar A/C with R407C is protective to the enviorment, It is good for hunman's healthy.

5. Compared to the normal air conditioner, 50% of electricity can be saved by them.

6. The air conditioner can work normally between the temperatures -25 degree Celsius and 54 degree Celsius, If the temperature is over 50 celsius degree, the compressor will keep itself in a state of rest for protection. If the temperature returns to normal(-25celsius degree to 50 celsius degree), it will continue to work automatically.

Solar-Power Air Conditioner Installation Steps

 1.  Indoor parts installation: to install the indoor parts to a suitable location.

2.  Connect copper pipes, lines and water pipes with indoor parts. Connectors should be tightened to prevent leakage.

3.  Outdoor parts and solar panel installation: to select a suitable location to install and secure the outdoor parts and solar panel.

4.  Air vacuuming: to turn two stop-valves of solar panel loose completely to allow air to expel from low-pressure tripe-pipe-valve of outdoor parts.

5.  Leakage checking: to apply soap water to all connectors for checking leakage or not.

6.  Pilot run.

FAQ
 1.What is the warranty years and how about after sale service?
The warranty of the solar A/C is 6-7 years.
We give 1% equipments, it means we give 1 unit free for every 100 units purchase. Compared to normal air conditioners, the difference just lies in the solar panel which is of good quality. In case there is any problem aroused, they can be repaired as the normal ones in our clients’ own countries. But incase there is any damage of main spare parts like compressors or solar panels, you should purchase them of the same type from us and replace the damaged ones.
 
2.How about the solar energy?
The source of solar energy is the natural light energy, heat energy and the radiant energy in the environment absorbed by the solar-panel. Solar energy and electricity work together and the ratio of them is 50%. Only when the electricity and solar energy work together can ensure the normal works of our products, it can't work using 100% solar energy or 100% electricity alone.

3.Can our solar A/C work in bad weather?
Our clients should feel ease about it that our A/C can work normally no matter in what kind of weather.
Our solar panel is the solar collector which could collect and store the heat energy, light energy, the radiant energy of the environment. Solar energy can be collected no matter in the day time or at night, no matter in the raining day or the sunshine day. When there is no sunshine, the solar panel could also collect the light energy and heat energy, which can never be exhausted as there is a continual supplement, even when there are connected raining days or very cold days with very low temperature. Besides, the consumption of solar energy is little compared to the absorbed energy, the solar energy would never be exhausted, and the product can always work normally no matter in what kinds of weather.

4. What’s the limited temperature our solar A/C can be used normally?

As long as the temperature isn't higher than 54℃ and isn't lower than -25℃, our solar A/C can work normally, no matter High Humidity or low humidity, the performance won't be affected by the variance.

5. What’s the core cooling principle of solar energy?
Solar energy providing the absorption type of refrigerator with the heat-carrying water (refrigerant) which the generator needs, other procedures would be done by generator just like normal air conditioners. The heating principle is the same with the cooling principle.

6. How the electricity saved?
The solar air conditioners powered by the solar energy and electricity together, thus the electricity would be saved.
 
7. What’s our products’ energy efficiency?
Currently there is no calculating method for solar air conditioners, we have the EER and star rating but it isn't our true efficiency. Our product is changed from normal air conditioners, and our products can save 50%-70% electricity because there is solar panel which can help saving electricity.
We have the efficiency rating:
EER star
12000btu 2.91 4star
18000btu 2.84 3star
24000btu 2.7 3star
35000btu 2.64 3star
42000btu 2.6 3star
The EER and star rating is calculated by the way:
Cooling Efficiency/normal AC's electricity consumed.
Actually our solar AC's electricity consumed is just about half of it.

Though our normal air conditioner's rating star isn't high, but the higher of it, the Prices will be much higher, products rate 3 or 4 is OK. Currently there are few air conditioners have star 2 and there is none has star 1 in China.

8. What is our core technology?
The core technology mostly lies in the solar panel and compressor.
Our solar panel is made of silicon. There are many small components in solar panel. They are mainly the parts of heat collecting, assistant parts of converting heat or cool; Our compressors is different from normal air conditioners', they are improved by very specific technology, which is complex and difficult to understand by un-specialized people.
More details are secret
Note: The compressor or solar panel can't be replaced by clients themselves, so if there is some damage of them or the warranty period passed, they should be replaced by the same as the original ones which you could purchase from us.
