Progress in heat pump engineering

FEB 01, 1952
The heat pump, essentially a refrigerator working in reverse, can be used to transfer heat energy from water, from air, or from the earth to heat buildings. It can also be used to cool buildings by transferring inside heat to the outside.
E. B. Penrod

During the last two decades considerable effort has been made to introduce the heat pump for heating and cooling buildings. The capacity of the heat pumps, installed, ranges from three tons to five hundred and fifty tons of refrigeration. The heat sources and the heat sinks are atmospheric air, water, and the earth. In the commercial field the heat pump principle has proved to be practical and satisfactory wherever suitable heat sources and heat sinks were available.
