Abstract
Abstract An adsorptional heat pump for using as a cooler or a heater which comprises a pair of rotary module discs and plurality of thermosyphons. The rotary module discs comprise a plurality of modules of which each of two modules are positioned in order to be opposite with each other. The thermosyphon is positioned between the two opposite modules, so that both ends thereof are respectively inserted into corresponding modules and has a good heat transferring feature, so that the thermosyphon provides an internal heat exchange between the modules. The heat pump according to the invention repeatedly and periodically carries out consequent processes such as generation. →heat exchange→adsorption→heat exchange→generation. The present invention can provide a heat pump having a promoted efficiency.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
112 words
A heat pump of the adsorption type comprising; at least one rotary module disc which includes a disc axis and a plurality of individual, sector-shaped modules each having radially inner and outer flow-connected compartments, each of said modules having a quantity of vaporizable liquid refrigerant and also having means disposed in said inner compartment for adsorbing said refrigerant; a plurality f thermosyphons each of which is respectively positioned and operatively connected between diametrically opposed modules, each of said thermosyphons having opposed operative ends respectively inserted into the inner compartments of corresponding ones of said opposed modules; and means for rotating said rotary module disc with the disc axis being oriented substantially horizontally.
Claim 2
Dependent Claim
112 words
A heat pump of the adsorption type comprising; at least one rotary module disc which includes a disc axis and a plurality of individual, sector-shaped modules each having radially inner and outer flow-connected compartments, each of said modules having a quantity of vaporizable liquid refrigerant and also having means disposed in said inner compartment for adsorbing said refrigerant; a plurality f thermosyphons each of which is respectively positioned and operatively connected between diametrically opposed modules, each of said thermosyphons having opposed operative ends respectively inserted into the inner compartments of corresponding ones of said opposed modules; and means for rotating said rotary module disc with the disc axis being oriented substantially horizontally.
Claim 3
Dependent Claim
68 words
The heat pump as claimed in claim 1, wherein said modules are sealed off from the adjacent modules, wherein said thermosyphons are operative to transfer heat only when the corresponding module from which heat is to be transferred is in a lower position relative to a horizontal plane running through the disc axis relative to the position of the corresponding module to which heat is to be transferred.
Claim 4
Dependent Claim
43 words
The heat pump as claimed in claim 1, wherein each of said thermosyphons includes an elongated central portion disposed within said respective opposed modules and interconnecting the respective thermosyphon operative ends, and wherein each of said central portions intersectingly traverses the disc axis.
Claim 5
Dependent Claim
25 words
The heat pump as claimed in claim 1, wherein each of said thermosyphons includes heat transfer fin means connected to said respective thermosyphon operative ends.
Claim 6
Dependent Claim
74 words
The heat pump as claimed in claim 1, further comprising a pair of stationary fan means for providing axially directed air flow past successive one of said outer module compartments, said pair of fan means being disposed diametrically opposite relative to the disc axis, with one of said fan means being positioned above a horizontal plane passing through the disc axis, and with the other of said fan means being positioned below said plane.
