I.Whats the solar collector and how it works?                                    
Solar collector is a collecting machine which absorbs the sun energy to heating ,then supply hot water,space heating and even space cooling via used                                     
of an absorption chiller or dessicant cooler technology.It works under sun,the absorbing tubes convert the solar energy into heat energy and transfer                                    
heat to the heat pipes by aluminum fins,the liquid in the heat pipe turns into vapour and rieses to the condenser and release the energy to water                                     
or other liquid,the the heating liquid back to the bottom of  heat pipe and circulation again.                                    
                                    
II.Why need solar collector?                                    
Sun energy is free for charge,we can save a  lot of money and also sun energy is clear ,we also contribute our power to                                     
the environment protection.Why we not choose it!!!!
