An ice-making heat pump system is disclosed which includes a number of evaporator freezing plates, each of the plates having two fluid passageways therein. One of the passageways is arranged to conduct boiling refrigerant fluid for freezing water on the surfaces of the plate. The other passageway is arranged to conduct warm condensed refrigerant for harvesting ice formed on the plate surface. A fluid valve arrangement is also provided to connect the plates with the rest of the system so that ice can be selectively formed and released from the outer surfaces of the freezing plates.

An improved evaporator for an ice-making heat pump of the type which includes a compressor for circulating a supply of refrigerant, a condenser, and an evaporator, said evaporator adapted to be arranged in heat exchange relationship with water to be in contact therewith and comprising a plurality of freezing plates, each of said freezing plates having a first passageway therein arranged to conduct relatively cold evaporating refrigerant therethrough in heat exchange relationship with water to be in contact with the outer surfaces of said freezing plates to form ice on the outer surface of at least one of said freezing plates, and a second passageway therein arranged to conduct relatively warm refrigerant therethrough in heat exchange relationship with the ice to be formed on the outer surface of at least one of said freezing plates to release said ice, each of said passageways having inlet and outlet ends, respectively, and valve means coupled between said freezing plates arranged to selectively direct said refrigerant between said first and second passageways in each of said freezing plates to enable said ice to be selectively formed on and released from the outer surfaces of said freezing plates when said evaporator is operatively connected to said heat pump.
