Refrigeration apparatus and method for a fluid dispensing device

摘要: Preferred embodiments of the present invention have a nozzle assembly capable controlling pressure comestible fluid exiting assembly, refrigeration system in which refrigerant and temperature is controllable to enable control temperature, heat exchangers connected cool nozzles, an ultraviolet sterilization for sterilizing locations outside inside system, hand held dispenser cooling selectively dispensing one several fluids supplied thereto. To provide at rack nozzles highly preferred embodiment, each preferably has valve movable through number closed positions change within nozzle. Prior dispense, reduced by actuating its range positions. improve efficiency, employs adjacent assemblies. Due their close assemblies, generate convective recirculation assemblies discharge openings thereof. The can take form multi-fluid gun having such exchanger relationship as described above. further evaporator regulator upstream compressor hot gas bypass temperature.
