Abstract
Abstract A conditioning method and an air-conditioner for carrying out such method which comprises, in a compression, cooling and expansion cycle, a drying operation performed prior to the expansion. According to the invention, a dryer is alternately operated in an adsorption phase and a regeneration phase, depending on whether it communicates with the outlet or the inlet of a heat exchanger. The present method and device can be advantageously applied to environment control in the field of aircraft and automotive vehicle air conditioning.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
299 words
An air-conditioner comprising: (a) a compressor; (b) a first dryer; (c) a first conduit for delivering air from said compressor to said first dryer; (d) a first exchanger; (e) a second conduit for delivering air from said first dryer to said first exchanger; (f) a third conduit leading from said first conduit to said second conduit around said first dryer; (g) a first valve located in said third conduit; (h) a water extractor that removes the condensation water in liquid phase issuing from said first exchanger; (i) a fourth conduit for delivering air from said first exchanger to said water extractor; (j) a second dryer that absorbs the water not extracted in liquid phase by said water extractor and water in vapor phase; (k) a fifth conduit for dlivering air from said water extractor to said second dryer; (l) an expansion turbine; (m) a sixth conduit for delivering air from said second dryer to said expansion turbine; (n) a seventh conduit leading from said fifth conduit to said sixth conduit around said second dryer; (o) a second valve located in said seventh conduit; (p) a fan; (q) a shaft on which said compressor, said expansion turbine, and said fan are all commonly mounted; (r) an eighth conduit for delivering air from said expansion turbine to an enclosure to be air-conditioned; (s) a ninth conduit for delivering stale air from the enclosure to be air-conditioned to said first exchanger; (t) a tenth conduit for delivering air from said first exchanger to said fan; and (u) an eleventh conduit for delivering air from said fan to the external environment, whereby, in use, one of said first and second dryers is operated in a regeneration phase while the other one of said first and second dryers is operated in an adsorption phase.
Claim 2
Dependent Claim
299 words
An air-conditioner comprising: (a) a compressor; (b) a first dryer; (c) a first conduit for delivering air from said compressor to said first dryer; (d) a first exchanger; (e) a second conduit for delivering air from said first dryer to said first exchanger; (f) a third conduit leading from said first conduit to said second conduit around said first dryer; (g) a first valve located in said third conduit; (h) a water extractor that removes the condensation water in liquid phase issuing from said first exchanger; (i) a fourth conduit for delivering air from said first exchanger to said water extractor; (j) a second dryer that absorbs the water not extracted in liquid phase by said water extractor and water in vapor phase; (k) a fifth conduit for dlivering air from said water extractor to said second dryer; (l) an expansion turbine; (m) a sixth conduit for delivering air from said second dryer to said expansion turbine; (n) a seventh conduit leading from said fifth conduit to said sixth conduit around said second dryer; (o) a second valve located in said seventh conduit; (p) a fan; (q) a shaft on which said compressor, said expansion turbine, and said fan are all commonly mounted; (r) an eighth conduit for delivering air from said expansion turbine to an enclosure to be air-conditioned; (s) a ninth conduit for delivering stale air from the enclosure to be air-conditioned to said first exchanger; (t) a tenth conduit for delivering air from said first exchanger to said fan; and (u) an eleventh conduit for delivering air from said fan to the external environment, whereby, in use, one of said first and second dryers is operated in a regeneration phase while the other one of said first and second dryers is operated in an adsorption phase.
Claim 3
Dependent Claim
20 words
An air-conditioner as recited in claim 1 and further comprising a twelfth conduit for delivering external air to said compressor.
Claim 4
Dependent Claim
21 words
An air-conditioner as recited in claim 1 and further comprising a thirteenth conduit for introducing outside air into said ninth conduit.
Claim 5
Dependent Claim
51 words
An air-conditioner as recited in claim 1 and further comprising: (a) a second exchanger located in said sixth conduit; (b) a fourteenth conduit for delivering air from the enclosure to be air-conditioned to said second exchanger; and (c) a fifteenth conduit for delivering air from said second exchanger to said fan.
Claim 6
Dependent Claim
65 words
An air-conditioner as recited in claim 4 and further comprising: (a) a first spray nozzle located in said ninth conduit; (b) a second spray nozzle located in said fourteenth conduit; (c) a sixteenth conduit for delivering condensation liquid from said water extractor to said first spray nozzle; and (d) a seventeenth conduit for delivering condensation liquid from said water extractor to said second spray nozzle.
Claim 7
Dependent Claim
38 words
An air-conditioner as recited in claim 1 and further comprising: (a) a first spray nozzle located in said ninth conduit and (b) a sixteenth conduit for delivering condensation liquid from said water extractor to said first spray nozzle.
Claim 8
Dependent Claim
44 words
An air-conditioner as recited in claim 1 wherein each one of said first and second dryers comprises a drum which is movable about an axis and which comprises cyclically disposed sectors adapted to operate successively in the adsorption phase and in the regeneration phase.
Claim 9
Dependent Claim
76 words
An air-conditioner as recited in claim 7 wherein: (a) said drum is disposed in a space delimited by a tank and a cap; (b) said drum is adapted to rotate within said space so as to present cyclically each one of said sectors in a regeneration zone and in an adsorption zone; and (c) said regeneration zone and said adsorption zone are delimited by walls and are adapted to communicate with associated ones of said conduits.
Claim 10
Dependent Claim
