The feasibility of effective cooling using two solid-gas reactors has been tested experimentally with a low-power machine. The ambient temperature was 313 K. The power output of the reactors has been determined as a function of cooling temperature for air conditioning and refrigeration. Refrigeration requires a heat-transfer fluid temperature of 273 K, while air conditioning of buildings requires 285-288 K. For personal air-conditioning units, the desired temperature is between 310 and 313 K. We have used a model to validate charts for the power produced per unit of reactive volume with proper consideration of desired temperatures for both reactors.
