Abstract
An air conditioning system includes a multiple effect evaporative condenser, at least one compressor, at least one heat exchanger, an expansion valve, and at least one multiple-effect evaporative condensers. The multiple effect evaporative condenser and the heat exchanger utilize a highly efficient heat exchanging pipe for performing heat exchange between water and refrigerant.
Claims131
A multiple-effect evaporative condenser for cooling a predetermined amount of refrigerant by a predetermined amount of cooling water, comprising:
- a pumping device adapted for pumping said cooling water at a predetermined flow rate;
- a tower housing having an air inlet and an air outlet, wherein an air draft is drawn between said air inlet and said air outlet;
- a first water collection basin mounted in said tower housing for collecting said cooling water pumped from said pumping device;
- a first cooling unit comprising a plurality of heat exchanging pipes and a first fill material unit provided underneath said heat exchanging pipes, wherein said cooling water collected in said first water collection basin is arranged to flow through exterior surfaces of said heat exchanging pipes and said first fill material unit;
- and
- a second water collection basin positioned underneath said first cooling unit for collecting said cooling water flowing from said first cooling unit, wherein said cooling water collected in said second water collection basin is arranged to be reused in said first water collection basin, wherein said refrigerant flows through said heat exchanging pipes of said first cooling unit, in such a manner that said refrigerant is arranged to perform highly efficient heat exchanging process with said cooling water for lowering a temperature of said refrigerant, wherein said predetermined amount of air is drawn into said tower housing through said air inlet for performing heat exchange with said cooling water flowing through said first fill material for lowering a temperature of said cooling water, wherein said air having absorbed said heat from said cooling water is discharged out of said tower housing through said air outlet.
3 more elements
A high efficiency heat exchanging pipe, comprising:
- a pipe body;
- a plurality of inner heat exchanging fins spacedly and protrudedly extended along an inner surface of said pipe body in a spiral manner for enhancing heat exchange surface area of said corresponding heat exchanging pipe, and for guiding a fluid flow on said inner surface of said corresponding heat exchange pipe along said spiral path of said inner heat exchanging fins;
- and
- a plurality of outer heat exchanging fins spacedly and protrudedly extended along an outer surface of said pipe body for enhancing heat exchange surface area of said corresponding heat exchanging pipe and for guiding a fluid flow on said outer surface of said corresponding heat exchange pipe along said outer heat exchanging fins.
1 more element
A heat exchanger for facilitating heat exchange between a predetermined amount of water and a predetermined amount of refrigerant, comprising:
- a heat exchanger housing having a water inlet, a water outlet, a refrigerant inlet, a refrigerant outlet, and a cover detachably provided on said heat exchanger housing,
- an upper water chamber provided on an upper portion of said heat exchanger housing, and is communicated with said water outlet;
- a lower water chamber provided on a lower portion of said heat exchanger housing, and is communicated with said water inlet;
- and
- at least one heat exchanging pipe extended between said upper water chamber and said lower water chamber, wherein water having a relatively low temperature is arranged to enter said heat exchanger through said water inlet and temporarily store in said lower water chamber, wherein said water is pumped up said heat exchanger housing through said heat exchanging pipes and temporarily store in said upper water chamber and leaves said heat exchanger through said water outlet, wherein said heat exchanging pipe comprises a pipe body, a plurality of inner heat exchanging fins inwardly extended from said pipe body, and a plurality of outer heat exchanging fins outwardly extended from said pipe body;
- wherein said refrigerant is guided to enter said heat exchanger through said refrigerant inlet and flow through an exterior of outer heat exchanging fins of said heat exchanging pipes for performing heat exchange with said water flowing through said corresponding inner heat exchanging fins of said heat exchanging pipes, wherein heat is absorbed by said refrigerant which becomes evaporated, wherein vapor of said refrigerant is then guided to leave said heat exchanger through said refrigerant outlet.
3 more elements
A cooling device for cooling a predetermined amount of refrigerant, comprising:
- a tubular housing having a refrigerant entrance formed at a bottom portion thereof, and a refrigerant exit formed at a top portion of said tubular housing, wherein said refrigerant is arranged to enter said tubular housing through said refrigerant entrance, while said refrigerant is arranged to leave said cooling device through said refrigerant exit, wherein said tubular housing further has a water entrance provided at a top portion thereof, and a water exit provided at a bottom portion of said tubular housing, wherein water is arranged to flow into said tubular housing through said water entrance;
- and
- a heat exchanging pipe extended from said refrigerant entrance and said refrigerant exit, wherein said refrigerant is arranged to flow through said heat exchanging pipe in said tubular housing, wherein said water flowing through said tubular housing is arranged to perform heat exchange with said refrigerant flowing through said heat exchanging pipe.
