Abstract
A refrigeration system includes a tubing system, a sensor circuitry, a fan, and a controller. The tubing system has tubes located adjacent to component of the refrigeration system. The tubes have holes on their surface. The fan is downstream of the tubes. The fan pulls sampled air though the tubes and direct the sampled air toward the sensor circuitry. The controller receives a signal that indicates that the sampled air comprises a mixture of air and refrigerant particles. In response to receiving the signal, the controller determines that there is refrigerant leakage from at least one of the one or more components and triggers a mitigation plan associated with the refrigerant leakage.
