A cooler for cooling a plurality of brands of liquid beverages for delivery at taps for dispensing to customers at a desired chilled temperature. The cooler has a heat exchanger with a shell having channels passing through it, each communicating with a keg containing a beverage and a dispensing tap.

A cooler for cooling a plurality of brands of liquid beverages for delivery at taps for dispensing to customers at a desired chilled temperature. The cooler has a heat exchanger with a shell having channels passing through it, each communicating with a keg containing a beverage and a dispensing tap. Chilled coolant, controlled by the heat exchanger flows through the shell to cool the beverage flowing through the channels to the desired temperature. The temperature of the coolant is controlled by a temperature controller to maintain a narrow desired temperature range, just above the freezing temperature. The cooler is capable of cooling each of the channels without having to be installed in a walk-in cooler, allowing its installation proximate the serving taps. Also, the kegs containing the various brands of beer which are connected to the heat exchanger do not have to be kept in a walk-in cooler. 30° F. to 34° F. range.

A combined cycle power generating system as claimed in claim 1, wherein in one portion of the circuit, a liquid is conveyed, in that in another portion of the circuit a vapor derived from the liquid is conveyed, and in that the gravitational compression of the vapor is enhanced by drenching thereof with a portion of the liquid. 17. A combined power generating system as claimed in claim 1, wherein the circuit comprises a first substantially vertical column for conveying a fluid from a lower level to a higher level, in that the circuit comprises a second substantially vertical column for conveying the fluid from the higher level to the lower level, in that heat is transferred to the fluid in at least one position in the circuit and in that power is extracted form the fluid in at least one other position in the circuit. 18. A combined cycle power generating system as claimed in claim 17, wherein the fluid comprises two substances which are completely soluble in one another at all operating temperatures of the system. 19. A combined cycle power generating system as claimed in claim 18, wherein the latent heat of evaporation of the one substance is substantially more than the latent heat of evaporation of the other substance, so as to cause preferential condensation of the one substance to result in drenching of the vapor of the other substance, which in turn causes the fluid to self-circulate. 20. A combined cycle power generating system as claimed in claim 1, wherein the circuit comprises a first substantially vertical column for conveying a liquid from a lower level to a higher level, in that the circuit comprises a second substantially vertical column for conveying a vapor from the lower level to the higher level, in that the circuit comprises a third substantially vertical column for conveying a mixture of the liquid and the vapor from the higher level to the lower level, in that heat is transferred to the fluid at any position in the circuit and in that power is extracted form the mixture at the lower level in the third substantially vertical column. 21. A combined cycle power generating system as claimed in claim 1, wherein it is continuous in that it comprises a first column for conveying air from a lower level to a higher level causing the air to expand as its pressure decreases, in that it comprises a second column for conveying a mixture of air, water vapor and liquid water from the higher level to the lower level, thereby compressing the air forming part of the mixture, and in that it comprises a third column for conveying liquid water displaced by a pump from the lower level to the higher level. 22. A combined cycle power generating system as claimed in claim 1, wherein the circuit comprises a first substantially vertical column for conveying a first liquid from a lower level to a higher level, in that the circuit comprises a second substantially vertical column for conveying a first vapor derived from the first liquid from the higher level to the lower level after heating by the second fluid, in that the circuit comprises a third substantially vertical column for conveying a second liquid from the higher level to the lower level, in that the circuit comprises a fourth substantially vertical column for conveying a second vapor derived from the second liquid from the lower level to the higher level, in that heat is transferred from the first liquid to the second liquid at the lower level and in that power is extracted form the second liquid in the proximity of the lower level. 23. A combined cycle power generating system as claimed in claim 22, wherein the first and second liquids are selected on the basis that the variations in their boiling points caused by variations in pressure are sufficient to cause the first and second vapors to self circulate in the circuit. 24.
