Service Access Mechanism for Refrigerant Leak Sensors

Abstract

A cooling system comprises a cabinet, a compressor, an evaporator, a refrigerant, at least one sensor, a controller, and at least one sliding mechanism. The cabinet comprises a first compartment and a second compartment. The compressor is positioned within the cabinet. The evaporator is positioned within the cabinet. The refrigerant is received by the compressor and the evaporator. The sensor measures refrigerant leak data. The controller determines the presence of a refrigerant leak based on the refrigerant leak data from the sensor. The sliding mechanism is configured to slide in and out of the cabinet. The sliding mechanism comprises at least one sensor.
