Abstract
Abstract An integrated heat exchange and heat storage system using thermochemical reactions which comprises a first plurality of parallel adjacent tubes containing an element for storing and yielding heat; and a second plurality of tubes parallel to said first plurality of tubes and interposed therebetween and containing a fluid heat vehicle, the first and second plurality of tubes being disposed in a receptacle whose major axis extends parallel to the axis of the tubes, the voids between the various tubes being filled with a stagnant liquid serving to facilitate heat exchange between the fluid heat vehicle and the element for storing and yielding heat.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
106 words
An integrated heat exchange and heat storage system using thermochemical reactions, characterized in that it comprises: a first plurality of parallel adjacent tubes containing an element for storing and yielding heat; and a second plurality of tubes parallel to said first plurality of tubes and interposed therebetween and containing a fluid heat vehicle, said first and second plurality of tubes being disposed in a receptacle whose major axis extends parallel to the axis of the tubes, the voids between the various tubes being filled with a stagnant liquid serving to facilitate heat exchange between the fluid heat vehicle and the element for storing and yielding heat.
Claim 2
Dependent Claim
106 words
An integrated heat exchange and heat storage system using thermochemical reactions, characterized in that it comprises: a first plurality of parallel adjacent tubes containing an element for storing and yielding heat; and a second plurality of tubes parallel to said first plurality of tubes and interposed therebetween and containing a fluid heat vehicle, said first and second plurality of tubes being disposed in a receptacle whose major axis extends parallel to the axis of the tubes, the voids between the various tubes being filled with a stagnant liquid serving to facilitate heat exchange between the fluid heat vehicle and the element for storing and yielding heat.
Claim 3
Dependent Claim
17 words
A system according to claim 1, characterised in that the heat exchanger element is an exo-endothermic mixture.
