Thermo-chemical recuperation systems, devices, and methods are provided in accordance with various embodiments. Embodiments may generally relate to the field of refrigeration and/or heat pumping. Within that field, some embodiments apply to the recuperation or recapturing of both thermal and chemical potential in a freeze point suppression cycle. Some embodiments include a method and/or system of thermo-chemical recuperation that includes creating a flow of ice and flowing a brine against the flow of the ice. Some embodiments manage the thermal and chemical potentials by mixing a dilute brine stream exiting an ice mixing vessel with an ice stream before it enters the ice mixing vessel. By controlling this mixing in a counter-flow or step-wise cross flow manner with sufficient steps, both the thermal and chemical potential of the dilute bine stream may be recuperated.

The conditioning systems can operate in various modes, including an adiabatic mode and an evaporative mode, depending on outdoor air conditions. The systems can operate in a blended mode between the adiabatic mode and the evaporative mode by varying the distribution of return water from the recovery coil into at least partially isolated sections of a storage tank, and selectively directing cold water from the evaporative cooler into the tank. The mix of warm and cold water exiting the tank can be varied to maintain the cold-water supply at or near a set point temperature for the heat load.
