Abstract:
1. An air heating, air conditioning and water heating system, comprising: a plurality of connecting pipes adapted for carrying a flow of a predetermined amount of refrigerant; a multi-communicative valve unit; a compressor arranged for compressing said refrigerant in a state of superheated vapor; a condenser communicated with said compressor through said multi-communicative valve unit and said connecting pipes, wherein a first predetermined amount of heat exchange medium circulates through said condenser; a heat exchanger communicated with said condenser through said multi-communicative valve unit and said connecting pipes, wherein a second predetermined amount of heat exchange medium circulates through said heat exchanger; an expansion valve communicative between said heat exchanger and said condenser; and a water heater communicated with said heat exchanger and said compressor through said multi-communicative valve unit and said connecting pipes, wherein said water heater is arranged to store a predetermined amount of water, wherein said multi-communicative valve unit is arranged to be operated to selectively establish at least an air conditioning route and an air heating route for said refrigerant, (i) wherein in said air conditioning route, said refrigerant in superheated vapor state is arranged to sequentially flow into said water heater from said compressor for releasing a predetermined amount of heat into said water stored in said water heater for producing a predetermined amount of heated water, wherein said refrigerant leaving said water heater is guided to flow into said condenser through said multi-communicative valve trait for extracting a predetermined amount of heat to said first predetermined heat exchange medium, wherein said refrigerant leaving said condenser is arranged to flow into said heat exchanger through said expansion valve and said multi-communicative valve unit for absorbing a predetermined amount of heat from said second predetermined heat exchange medium, wherein said refrigerant leaving said heat exchanger is arranged to flow into said compressor through said multi-communicative valve unit to perform another heat exchange cycle for producing refrigeration; (ii) wherein in said air heating route, said refrigerant in superheated vapor state is arranged to sequentially flow into said water heater from said compressor for releasing a predetermined amount of heat into said water stored in said water heater for producing a predetermined amount of heated water, wherein said refrigerant leaving said water heater is guided to flow into said heat exchanger through said multi-communicative valve unit for extracting a predetermined amount of heat to said first predetermined heat exchange medium, wherein said refrigerant leaving said heat exchanger is arranged to flow into said condenser through said expansion valve and said multi-communicative valve unit for absorbing a predetermined amount of heat from said second predetermined heat exchange medium, wherein said refrigerant leaving said condenser is arranged to flow into said compressor through said multi-communicative valve unit to perform another heat exchange cycle for producing air heating; and (iii) wherein said multi-communicative valve unit is arranged to be operated to selectively establish a water heating route in additional to said air conditioning route and said air heating route for said refrigerant, wherein in said water heating route, said refrigerant in superheated vapor state is arranged to sequentially flow into said water heater from said compressor for releasing a predetermined amount of heat to said water stored in said water heater, wherein said refrigerant leaving said water heater is guided to flow into said condenser through said multi-communicative valve unit for absorbing heat from said first predetermined heat exchange medium, wherein said refrigerant leaving said condenser is arranged to flow into said compressor through said multi-communicative valve unit to perform another heat exchange cycle for producing heated water in said water heater.
