In some aspects, a cooling system is configured to enter into a storage configuration or a wintenzation configuration. In the wintenzation configuration, refrigerant used in the cooling system is stored in an adsorbent in an adsorbent chamber. ## Claims ### Claim 1 A control system of a cooling system, the control system configured to: cause an adsorbent chamber to enter into a cooling mode and the recharging mode, the adsorbent chamber fluidly coupled to an evaporator, the adsorbent chamber containing an adsorbent that absorbs the refrigerant in a cooling mode and desorbs the refrigerant in a desorbing mode, receive a storage condition, determine if the cooling system is to enter into a storage configuration or a winterization configuration based on the storage condition, and in response to determining if the cooling system is to enter into the winterization configuration, cause the cooling system to enter into the winterization configuration. ### Claim 2 (depends on 1) The control system of a cooling system of claim 1, wherein the storage condition is an ambient temperature input at or below a predetermined ambient air temperature indicating a potential freezing condition of the refrigerant. ### Claim 3 (depends on 2) The control system of a cooling system of claim 2, wherein the ambient temperature input comprises temperature data from a sensor or a weather report. ### Claim 4 (depends on 1) The control system of a cooling system of claim 1, wherein the control system determines a rate of ambient air temperature decrease. ### Claim 5 (depends on 4) The control system of a cooling system of claim 4, wherein the winterization configuration comprises: a first configuration if the rate of ambient air temperature decrease is less than a first rate, wherein the first configuration comprises opening at least one valve between the evaporator and the adsorbent chamber to provide for adsorption of the refrigerant in the adsorbent; a second configuration if the rate of ambient air temperature decrease is at or greater than the first rate but less than a second rate, wherein the second configuration comprises adsorbing a portion of the refrigerant in the adsorbent chamber and at least a portion of the remaining refrigerant in a second adsorbent chamber; and a third configuration if the rate of ambient air temperature decrease is at or greater than the second rate, wherein the third configuration comprises applying additional heat to the evaporator to accelerate adsorption of the refrigerant in the adsorbent. ### Claim 6 (depends on 1) The control system of a cooling system of claim 1, further comprising at least one energy source thermally coupled to the adsorbent chamber and configured to heat the adsorbent chamber during the recharging mode, wherein the at least one energy source comprises exhaust from an engine of a vehicle. ### Claim 7 A method of operating a cooling system, the method comprising: providing an evaporator containing a refrigerant; providing an adsorbent chamber fluidly coupled to the evaporator, the adsorbent chamber containing an adsorbent that adsorbs the refrigerant in a cooling mode and desorbs the refrigerant in a desorbing mode; receiving a storage condition; determining, based on at least on the storage condition, if the cooling system is to enter a storage configuration or a winterization configuration; and in response to determining that the cooling system is to enter into the winterization configuration, causing the cooling system to enter into the winterization configuration. ### Claim 8 (depends on 7) The method of claim 7, wherein the storage condition is an ambient temperature input at or below a predetermined ambient air temperature indicating a potential freezing condition of the refrigerant. ### Claim 9 (depends on 8) The method of claim 8, further comprising: determining a rate of ambient air temperature decrease; wherein the winterization configuration comprises a first configuration if the rate of ambient air temperature decrease is less than a first rate, and wherein the first configuration comprises opening at least one valve between the evaporator and the adsorbent chamber to provide for adsorption of the refrigerant in the adsorbent; wherein the winterization configuration comprises a second configuration if the rate of ambient air temperature decrease is at or greater than the first rate but less than a second rate, and wherein the second configuration comprises adsorbing a portion of the refrigerant in the adsorbent chamber and at least a portion of the remaining refrigerant in a second adsorbent chamber; and wherein the winterization configuration comprises a third configuration if the rate of ambient air temperature decrease is at or greater than the second rate, and wherein the third configuration comprises applying additional heat to the evaporator to accelerate the adsorption of the refrigerant in the adsorbent. ### Claim 10 A cooling system, comprising: a refrigerant; an adsorbent; a detector to detect a condition requiring a winterization configuration of the cooling system, whereby upon detection of the condition, the cooling system is reconfigured to cause the adsorption of substantially all of the refrigerant on an individual molecular basis in the adsorbent. ### Claim 11 (depends on 10) The system of claim 10, wherein the adsorbent is zeolite. ### Claim 12 (depends on 10) The system of claim 10, wherein the adsorbent is a metal organic framework. ### Claim 13 (depends on 10) The system of claim 10, wherein the adsorbent is an electrically activated adsorbent. ### Claim 14 (depends on 10) The system of claim 10, wherein the condition is an ambient air temperature that may cause the refrigerant to freeze. ### Claim 15 (depends on 10) The system of claim 10, wherein the condition is an unintentional disconnection of a component of the cooling system.
