Abstract
Technologies are described herein for cooling systems. In some examples, a cooling system uses cooling cells to provide cooling to a space. The cells can include one or more adsorption chambers, whereby an adsorbent in the adsorption chamber causes a refrigerant (such as water) to evaporate. The action of evaporation removes heat from a cooling fluid, which is used to cool the space.
Claims12
A cooling system, comprising:
- an adsorbent chamber fluidically coupled to a condenser/evaporator, the adsorbent chamber containing an adsorbent that absorbs a refrigerant in a cooling mode and desorbs the refrigerant in a recharging mode;
- the condenser/evaporator fluidically coupled to the adsorbent chamber and a water reservoir, wherein the condenser/evaporator in the cooling mode provides for the evaporation of the refrigerant and in a recharging mode provides for the condensation of the refrigerant;
- the water reservoir fluidically coupled to the condenser/evaporator, the water reservoir configured to provide refrigerant to the condenser/evaporator;
- a valve to control a movement of refrigerant from and to the condenser/evaporator and the water reservoir;
- and
- a fan configured to control a temperature of the adsorbent during the cooling mode, wherein a speed of the fan is reduced to allow the temperature of the adsorbent to increase, thereby reducing a rate of adsorption, and wherein the speed of the fan is increased to allow the temperature of the adsorbent to decrease, thereby increasing a rate of adsorption.

A method of cooling an interior space, the method comprising:
- providing refrigerant into a condenser/evaporator from a water reservoir, wherein the condenser/evaporator is in fluidic communication with the water reservoir through a valve configured to reduce or stop the passage of refrigerant between the condenser/evaporator and the water reservoir;
- providing an adsorbent chamber containing an adsorbent that causes an evaporation of at least a portion of the refrigerant in the condenser/evaporator by adsorption of at least a portion of the refrigerant into the adsorbent, causing a reduction of a temperature of the refrigerant in the condenser/evaporator;
- transferring at least a portion of heat from a space coolant used to cool at least one space of a structure to the refrigerant in the condenser/evaporator, causing a reduction in a temperature of the space coolant;
- and
- changing a speed of a fan used to cool the adsorbent to change a rate of absorption of the refrigerant by the adsorbent.
