Abstract
An aqua-ammonia chiller apparatus is modified to include a heater function by providing a refrigerant by-pass for directing refrigerant to a heat exchanger capable of selectively functioning as a condenser during a heating mode or an evaporation during a cooling mode without passing through the apparatus condenser during the heating mode.
Claims72
An aqua-ammonia absorption apparatus for selective chiller/heater operation comprising:
- an absorber assembly comprising an absorber, an absorber heat exchanger and a generator absorber heat exchanger;
- a generator assembly;
- an absorption fluid loop for directing absorption fluid between said absorber and generator assemblies, said absorption fluid loop comprising first piping for directing rich absorption fluid from said absorber assembly to said generator assembly and second piping for directing weak absorption fluid from said generator assembly to said absorber assembly;
- a condenser;
- a heat exchanger for selectively functioning as a condenser or an evaporator;
- a refrigerant loop for directing refrigerant between said generator assembly, condenser, heat exchanger and absorber assembly;
- and
- refrigerant by-pass piping for directing refrigerant from said generator assembly to said heat exchanger without passing through said condenser.
An aqua-ammonia absorption apparatus for selective chiller/heater mode operation comprising an absorber assembly comprising an absorber, an absorber heat exchanger and a generator absorber heat exchanger, a generator assembly, an absorption fluid loop for directing absorption fluid between said absorber assembly and said generator assembly and directing absorption fluid in heal transfer communication in said absorber heat exchanger and therefrom to said generator assembly, a condenser, a heat exchanger for selectively functioning as an evaporator during a chiller mode and as a condenser during a heater mode, and refrigerant piping and one or more valves cooperating therewith for selectively directing ammonia refrigerant vaporized in said generator assembly to said heat exchanger without passing through said condenser during a heater mode.
An aqua-ammonia absorption apparatus for selective chiller/heater operation comprising:
- an absorber assembly comprising an absorber, an absorber heat exchanger and a generator absorber heat exchanger;
- a generator assembly;
- an absorption fluid loop and a single pump cooperating therewith for directing absorption fluid and refrigerant between said absorber and generator assemblies and for directing absorption fluid in heat transfer communication in said absorber heat exchanger and said generator absorber heat exchanger, said absorption fluid loop comprising first piping for directing absorption fluid and refrigerant from said absorber assembly to said generator assembly and second piping for directing weak absorption fluid from said generator assembly to said absorber assembly;
- a condenser;
- a heat exchanger for selectively functioning as a condenser or an evaporator;
- refrigerant loop for directing refrigerant between said generator assembly, condenser, heat exchanger and absorber assembly;
- and
- refrigerant by-pass piping for directing refrigerant from said generator assembly to said heat exchanger without passing through said condenser.
