Abstract

A chemisorption thermal system provides a cooling output by revolving an array of thermal elements through heat sink and heat source temperature zones defined within a cylindrical housing. Each thermal element is an enclosed elongated body having an absorbent material at one end and a reactant containing part at the other end. Reactant is desorbed from the absorbent material in one part of the thermal cycle, and then evaporated from the reactant containing part to provide a cooling output in another part of the cycle. It is particularly suitable as a vehicle air conditioner using the engine waste heat as a heat source and the vehicle radiator as a heat sink. The invention also makes use of dry chemical absorbent materials which have high heats of reaction allowing the system to have a high heat capacity and low volume. The thermal cycle may be reversed to provide a heating output.

Claims27

Dependent claims

A chemisorption apparatus for heating or cooling comprising:

(a) a housing in right cylindrical form divisible into temperature zones and having inlet and outlet apertures to said zones;
(b) a plurality of enclosed fins arrayed in a circle radially spaced from each other arranged coaxially with said housing, said array being movable through said temperature zones in a continuous thermal cycle, each of said fins having one part for containing an absorbent material and another part for containing a reactant material, said absorbent material being adapted to combine together with or to disassociate from said reactant material, depending on the temperatures applied to said parts of said fins as they are moved through said temperature zones;
(c) means for moving said array inc1uding a drive shaft to which said fins are mounted for rotation through the temperture zones of said housing;
and
(d) horizontal dividers arranged between each pair of adjacent fins for dividing said housing into an upper part and a lower part, said dividers extending to the housing and being adapted in conjunction with said rotatable fin array to form upper and lower temperature zones through which the array of fins rotates, wherein the absorbent containing parts of the fins constitute the lower parts thereof which are rotated through the lower temperature zone of the housing.

A chemisorption air conditioning apparatus for use in conjunction with a waste heat generating source such as a vehicle engine comprising:

(a) a cylindrical housing divisible into temperature zones and having inlet and outlet apertures to said zones;
(b) a plurality of enclosed fins arrayed in a circle radially spaced from each other, said array of fins being mounted to a drive shaft coaxial with said housing for rotation through the temperature zones of said housing in a continuous thermal cycle, each of said fins having one part for containing an absorbent material and another part for containing a reactant material, said absorbent material being adapted to combine together with or to disassociate a reactant material, depending on the temperatures applied to said parts of said fins as they are moved through said temperature zones;
(c) means for rotating said array of fins in a continuous thermal cycle through said temperature zones;
and
(d) horizontal dividers arranged between each pair of adjacent fins for dividing said housing into an upper part and a lower part, said dividers extending to the housing and being adapted in conjunction with said rotatable fin array to form upper and lower temperature zones through which the array of fins rotates, wherein the absorbent containing parts of said fins constitute the lower parts thereof which are rotated through the lower temperature zones of the housing.

A chemisorption apparatus for heating or cooling comprising:

(a) a cylindrical housing divisible into temperature zones and having inlet and outlet apertures to said zones;
(b) an array of thermal elements rotatable about a longitudinal axis of said cylindrical housing so as to rotate said thermal elements through said temperature zones, each thermal element being constructed so as to enclose a sealed, self-contained volume wherein a first portion of said volume includes means for holding an absorbent material therein and a second portion of said volume includes means for receiving a reactant material disassociated from the absorbent material, said absorbent and reactant materials being selected to combine together or to disassociate depending on the temperatures applied to said portions of said thermal elements as they are rotated through said temperature zones;
(c) a partition for dividing said housing into a first temperature zone through which the absorbent containing first portions of said thermal elements are rotated and a second temperature zone through which the reactant containing second portions of said thermal elements are rotated;
(d) means for dividing each of said first and second temperature zones into two temperature subzones, wherein the subzones of one of said temperature zones comprise a high temperature subzone and an intermediate temperature subzone, and the subzones of the other of said temperature zones comprise another intermediate temperature subzone and a low temperature subzone;
and
(e) means for rotating said array of thermal elements in a continuous cycle through said temperature zones.
