Abstract
Systems and methods for compressor-assisted sorption rate. A sorption system includes a sorber that absorbs and desorbs a refrigerant gas, such as ammonia, onto and from a coordinative complex compound. The system includes an evaporator, a condenser, and a compressor. The temperature and pressure of the gas within the sorber are monitored and the compressor is controlled to adjust the pressure to increase the absorption and desorption rates and increase the thermal cycle speed of the sorption system for applications such as laser systems requiring rapid, periodic cooling.

A thermal sorption system comprising:
- a sorber configured to at least one of absorb a sorber gas on solid complex compounds or desorb the sorber gas from the solid complex compounds;
- a thermal system configured to be in thermal communication with the solid complex compounds;
- an evaporator configured to be in thermal communication with a thermal load;
- a condenser;
- a compressor in fluid communication with the sorber, the evaporator, and the condenser, wherein the compressor is configured to compress the sorber gas to provide a pressure of the sorber gas within the sorber;
- one or more sensors configured to sample at least one of a temperature within the thermal sorption system or a pressure within the thermal sorption system;
- and
- a control system configured to:
