An ice harvesting/water chiller machine with an improved evaporator assembly having a plurality of plate-type heat exchangers oriented vertically in face-to-face parallel relation. A water reservoir is located above the heat exchangers. Water is distributed from the reservoir downwardly to flow over the outside surfaces of the heat exchangers to effect a substantially even distribution of water over the outside surfaces as it flows downwardly thereover. Cold refrigerant is distributed to the tops of the heat exchangers to cascade downwardly over the inside surfaces of the heat exchangers to effect a substantially even distribution of refrigerant over the inside surfaces as it cascades downwardly thereover. A cold refrigerant feed tube extends across the top of each heat exchanger substantially the entire width thereof. The tube has spaced openings along the tube over substantially the entire width of the heat exchanger which openings communicate with the interior of the heat exchanger.

This invention relates to a hot water system which utilizes heat from the refrigerant of a refrigeration system to produce hot water. A condenser as part of the hot water system is especially designed with greater heat exchange surface than would normally be provided with the refrigeration system so that water at convection flow and at a higher temperature than normal can be used in the condensing unit and yet achieve the necessary absorption of heat from the refrigerant passing through the condenser as required for proper operation of the refrigeration system. In one embodiment of the condenser unit a de-superheating coil is located at the top of the housing to overlie the top of an inverted can arrangement within the housing. Between the sides of the housing and the inverted can is located a sheet type heat exchange surface which is preferably pillowed. Water passages are defined between the sides of the housing and the inverted can arrangement by the layers of heat exchange sheet, and further passages are defined between the windings of the coil at the top.

This invention relates to a hot water system which utilizes heat from the refrigerant of a refrigeration system to produce hot water. The utilized heat consists of the superheat of the refrigerant vapor, the latent heat of condensation, and part of the sensible heat of the liquid refrigerant. The water passing through a water-cooled condenser, which is part of the refrigeration system, is heated to a selected temperature by removal of both the superheat of refrigerant vapor, the latent heat of condensation, and part of the sensible heat of the liquid refrigerant as it passes through the condenser. The condenser has a water inlet and an outlet between which is connected a hot water storage tank. As the water in the condenser is heated by absorption of the superheat of the refrigerant vapor, the latent heat of condensation, and part of the sensible heat of the liquid refrigerant passing therethrough, the heated water rises and flows by convection into the storage tank. Eventually the storage tank may fill completely with water of a selected temperature.

A refrigerated receiver in an automatic milking system has a coiled plate type heat exchanger disposed therein for pre-cooling milk before it is pumped into a milk cooling and storage tank. The heat exchanger is adapted for use in a direct expansion refrigeration system which can be operated in a heating mode to heat wash water as it is circulated through the system. The coiled plate type heat exchanger can be cleaned and inspected while in place inside the generally cylindrically shaped receiver unit as it is substantially vertically oriented with a generally annular space between successive turns of the coiled plate.

A bulk tank cooling and storage apparatus has heat exchange surfaces substantially covering the side and end walls of the tank. The tank is supplied with a horizontal rotating disc liquid distributor which uniformly distributes the liquid in a sheet over the heat exchange surfaces so that it flows downwardly over the surfaces in a thin film and is cooled by heat exchange operating in cooperation with the heat exchange surfaces. Even distribution of the liquid is provided by the rotating disc distributor which expels liquid from the periphery of the rotating disc and propels the liquid against the walls of the tank. Liquid fed into the tank is directed to the center of the rotating disc where a cylindrical dam or well holds a reservoir of the liquid and distributes it on the surface of the disc. The periphery of the disc may have a knife edge which helps the film of liquid to flow off smoothly without atomization.

Eventually the storage tank may fill completely with water of a selected temperature. A temperature responsive flow restriction device, or thermostat, is located between the water outlet of the condenser and the storage tank, which restricts the flow of water below a preselected temperature.
