Thermochemical Material Systems for Heating Ventilation and Air Conditioning

A system comprising:

• a thermochemical material (TCM) bed configured to receive a first air stream and to release a heated and dehumidified first air stream;
• and
• a heat exchanger comprising:
• a first inlet configured to receive the heated and dehumidified first air stream;
• a second inlet configured to receive a second air stream;
• a first outlet configured to release a heated second air stream into an indoor space;
• and
• a second outlet configured to release an exhausted first air stream;
• wherein:
• the TCM bed comprises a TCM,
• the TCM bed is configured to absorb a humidity from the first air stream resulting in the dehumidified and heated first air stream being released from the TCM bed,
• the heat exchanger is configured to transfer heat from the dehumidified and heated air stream to the second air stream, resulting in the heated second air stream being released via the first outlet and the exhausted first air stream being released via the second outlet.

A method comprising:

• contacting a mixed air stream with a sorbent material in a first channel;
• directing a first portion of the mixed air stream to interact with the sorbent material in a second channel;
• and
• releasing a second portion of the mixed air stream into an indoor space;
• wherein:
• the directing results in a humidity from the second portion of the mixed air stream to the sorbent material.
