Abstract: The present invention discloses a heat exchanger system for thermochemical storage and release. The system comprises a thermal exchange circuit with a heat exchanger fluid, the circuit further in thermal connection with a thermochemical module. The thermochemical module comprises a thermochemical material that stores and releases heat by a thermochemical exchange process under release or binding of a sorbate.
