Who discovered cooling?
The first known method of artificial refrigeration was demonstrated by William Cullen at the University of Glasgow in Scotland in 1748. Cullen used a pump to create a partial vacuum over a container of diethyl ether, which then boiled , absorbing heat from the surrounding air. The experiment even created a small amount of ice, but had no practical application at that time. ~From Wikipedia- Refrigeration

Can you vacuum from the high side?
One can apply vacuum at any point in a refrigeration loop to evacuate air and moisture. The compressor is not running during this time and so it doesn't matter.
