CLAIMS
1 1. A power unit for an absorption heat exchange

2 system compr ising a plurality of substantially coxially

3 positioned pipes of progressively larger diameters and of

4 sizes that provide a space between the inner and outer

5 walls of the adjacent pipes and including:
6 a. a hollow vertically oriented central
7 pipe;
8 b. an upper and a lower closure member
9 extending outwardly from the center

10 pipe and connected to the outer pipes

11 to form substantially annular
12 chambers, contiguous one to the
13 next, surrounding the center pipe; * c. means to provide heat in the central
15 pipe;
1 d. means for providing a cooling fluid to

17 contact the outer surface of the
1° largest diameter pipe;
19 e. means for discharging a refrigerant- 20 absorbant solution upon the inner y -ι
*iX walls of the substantially annular
11 chambers to desorb refrigerant from

2 J*3 solution with the absorbant and to

24 condense the refrigerant on the

3.5

outer walls of the chambers;
f. means for collecting the refrigerant and
solution separately in the
substantially annular chambers;
g. means for conveying the separately
collected solution from one chamber
to the next contiguous progressively
larger chamber and away from the
largest chamber; and
h. means for conveying the separately
collected refrigerant from the
chambers .
2. A power unit according to Claim 1 in wherein the closure member s are f langes substantially radially positioned with respect to the long itudinal ax is of the unit.
3. A power unit according to Claim 1 wherein the pipes are circular in cross-sectional shape.
4. A power unit according to Claim 1 wherein the inner pipes have generally radially positioned outwardly and upwardly projecting surface extending members at spaced intervals between the end closure members along the outer surface .
5. A power unit accord ing to Claim 4 wherein the surface extending members have sl its, essentially f orming spines .
6. A power unit according to Claim 5 wherein the surface extending members are positioned and attached to the outer surface of the pipes in a spiral or helical progression between the end closure members.
7. A power unit according to Claim 4 wherein the effect of the cooling fluid is enhanced by the provision of surface extending members on the outer side of the

- TRE
OMPI outside pipe .
8. A power unit according to Claim 4 wherein the means for applying a cooling fluid and effect is a water jacket.
9. A power unit for an absorption heat exchange system of generally symmetric construction about a central axis for an absorption refrigeration system, comprising!
a. a centrally positioned combustion chamber
member constructed with an outer
wall surface and an inner wall
surface, and formed to receive a
fuel-fired combustor positioned
to extend a flow of combustion
products into a combustion chamber
therein, the combustion chamber
member having generally radially
positioned outwardly projecting
surface extending surfaces at
spaced intervals, between opposite
ends along the outer wall surface,
in the direction of the central
axis, the ends comprising radially
formed closure members outwardly
projecting from the outer wall
surface;
b. a first desorber chamber member
surrounding the combustion chamber
member, spaced apart from the outer
wall thereof and attached to the
closure members, the first desorber
chamber member having generally
radially positioned out-wardly

OM 29 projecting surface extending
30 surfaces at spaced intervals between

31 the opposite ends along the outer

32 wall in the direction of the central

33 axis, the ends comprising radially

34 formed closure members outwardly

35 projecting from the outer wall
36 surface;
37 first desorber chamber, between the

38 combustion chamber member and the

39 first desorber chamber member,
40 having an inlet aperture at one
41 end and having a partition at
42 the opposite end, the partition
43 being positioned generally
44 parallel to the outer wall and
45 perpendicular to the closure member,

46 dividing the end of the first
47 desorber chamber into inner and outer

48 reservoirs, with an outlet aperture

49 from each reservoir;
50 d. second desorber chamber member surround¬

51 ing the first desorber chamber
52 member, spaced apart from the outer

53 wall thereof and attached to the
54 closure members; and
55 second desorber chamber between the
56 first desorber chamber member and

57 the second desorber chamber member

58 having an inlet aperture at one end

59 and having a partition at the
60 opposite end, the partition being

OMPI IS

positioned generally parallel to the
outer wall and perpendicular to the
closure member , dividing the end of
the second desorber chamber into
inner and outer reservoirs, with
an outlet aperture from each
reservoir.
10. A power unit according to Claim 9 wherein there is a fluid communication means between the inner reservoir of the first desorber chamber and the inlet to the second desorber chamber.
11. A power unit according to Claim 9 wherein the surface extending surfaces have slits, essentially forming spines.
12. A power unit according to Claim 11 wherein the surface extending surfaces are positioned and attached to the outer surface in a helical progression between the end closure members.
