PO-86-08-4 -- Room Coolers Prior to 1930 and the Technical Impediments to Their Development PDF

Numerous attempts at room cooling can be found beginning in the mid 1800’s. These attempts became more common as the refrigeration industry developed; however, it was not until the 1900’s that the many technical problems were solved, primarily by the fledqling household refrigeration industry. Isolated installations of room cooling for residential and commercial use gave way to mass production of engineered products by the late 1920’s, setting the stage for widespread manufacture and use in the 1930’s and beyond.
