System and method for removal of moisture and other sorbates

An apparatus, comprising:

• a preconditioning section of the apparatus comprising a preconditioning desiccant wheel comprising of two first sectors, namely a first process sector and a first reactivation sector;
• and
• a main section of the apparatus comprising a main desiccant wheel comprising of at least three second sectors, sequentially including an outside air sector, a second reactivation sector, and a second process sector, and
• a supplementary preconditioning section of the apparatus comprising a supplementary pre-conditioning desiccant wheel comprising of two supplementary sectors, namely a supplementary process sector and a supplementary reactivation sector, wherein
• an ambient airstream is sequentially dehumidified in the supplementary process sector of the supplementary pre-conditioning desiccant wheel, the first process sector of the preconditioning desiccant wheel, followed by dehumidification in the outside air sector of the main desiccant wheel, before being at least partially supplied for sequential reactivation with a heating unit at the second reactivation sector of the main desiccant wheel, followed by supplying to the first reactivation sector of the preconditioning desiccant wheel, and a second heating unit at the supplementary reactivation sector of the supplementary pre-conditioning desiccant wheel,
• the second process sector receives and dehumidifies a combination of a recirculated airstream from a cooling space and at least a first portion of a second preconditioned airstream, to output a dehumidified cooled airstream to the cooling space.

A method, comprising:

• sequentially dehumidifying an ambient airstream, in a first process sector of a preconditioning desiccant wheel and an outside air sector of a main desiccant wheel, and
• supplying the sequentially dehumidified ambient airstream, to a second reactivation sector of the main desiccant wheel with a heating unit for reactivation thereof, to output a first reactivation airstream, and
• directly supplying the first reactivation airstream, to a first reactivation sector of the preconditioning desiccant wheel for reactivation thereof, to output a second reactivation airstream, and
• supplying, a combination of a recirculated airstream from a cooling space and a first portion of a second preconditioned airstream, to a second process sector of the main desiccant wheel, to output a dehumidified cooled airstream to the cooling space.

A method, comprising:

• sequentially dehumidifying an ambient airstream, in a supplementary process sector of a supplementary desiccant wheel, a first process sector of a preconditioning desiccant wheel, and an outside air sector of a main desiccant wheel,
• supplying the sequentially dehumidified ambient airstream, to a second reactivation sector of the main desiccant wheel for reactivation thereof, with a heating unit to output a first reactivation airstream,
• directly supplying the first reactivation airstream, to a first reactivation sector of the preconditioning desiccant wheel for reactivation thereof, to output a second reactivation airstream, and
• supplying the second reactivation airstream, to a supplementary reactivation sector of the supplementary desiccant wheel for reactivation thereof, with a second heating unit to output a final reactivation airstream, and
• supplying, a combination of a recirculated room airstream from a cooling space and a first portion of a second preconditioned airstream, to the second process sector of the main desiccant wheel, to output a dehumidified cooled airstream to the cooling space.
