high pressure refrigerant using heat energy
Hi....am new to this field truly speaking....am an fashion design student...this Refrigeration and air-conditioning wont come in my field...but am interested so much in thermodynamics....
We have huge never-ending amount of solar energy...so using fresnel lens, concentrate at a spot to get really high temperatures (meaning huge amount of thermal energy)
So for commercial building's air-conditioning...
My doubt is "Cant we use thermal energy to compress a refrigerant instead of mechanical way to do??"
It could be done in two ways...one is directly applying heat energy to a closed vessel containing refrigerant or using high pressure steam for compressing mechanically (replacing electricity driven mechanical compresser).....
There the absorption system exists already which is being driven by using heat energy...but its performance could not able to meet the load....
Any help would be greatly appreciated in advance...
