Abstract:
1. An integrated plate heat exchanger, comprising: a reheater including laminated plates configured such that spaces are present between the laminated plates in a width direction of said heat exhanger which collectively define a first set of reheater channels and a second set of reheater channels, each for passage of compressed air, the reheater further including a compressed air inlet in communication with the first set of reheater channels and a compressed air outlet in communication with the second set of reheater channels; a chiller including other laminated plates configured such that other spaces are present between the other laminated plates in said width direction which collectively define a first set of chiller channels and a second set of chiller channels, said first set of chiller channels being for passage of a working fluid and said second set of chiller channels being for passage of the compressed air transferred thereto from the reheater, the chiller further including a working fluid inlet and a working fluid outlet connected to said first set of chiller channels; a pipe being disposed between said reheater and said chiller, said pipe including a first wall facing said reheater and a second wall facing said chiller, said first and second walls being spaced apart from one another to define a gap therebetween, said first and second walls extending at least from one terminal end to another terminal end of the reheater or chiller in a height direction of said heat exchanger, which runs crosswise to said width direction, and forming a partition between said laminated plates and said other laminated plates of said reheater and said chiller, respectively, said gap in said pipe providing a flow line through which the compressed air is upwardly passable from the reheater to the chiller, said first set of reheater channels being in communication with said pipe in a lower position thereof and said second set of chiller channels being in communication with said pipe in an upper position thereof such that the compressed air received through said compressed air inlet and passed through the first set of reheater channels is transferred to said second set of chiller channels via said flow line of said pipe; an adiabatic expansion chamber being disposed below the first and second sets of chiller channels, said adiabatic expansion chamber being in communication with said second set of chiller channels so as to receive the compressed air passed therethrough; and a condensation chamber in communication with the adiabatic expansion chamber, said condensation chamber being disposed below the first and second sets of reheater channels of the reheater, said condensation chamber further communicating with said second set of reheater channels, such that the compressed air from the second set of chiller channels is passed through the adiabatic expansion chamber and the condensation chamber, and then is passed through the second set of reheater channels to the compressed air outlet.
