Load conditions while waiting can vary with parking, vehicle and cooling arrangement. Do not infer a definite result from asphalt, shade or vehicle colour alone.
Record the parking location
Note location, direct sun or shade, surface, time and stop duration. Record which direction the vehicle door or body faces.
Separate three measurements
Place and identify ambient-air, vehicle-interior and product-zone sensors separately. If an active reefer is present, link operating status and alarms too.
Compare like operations
Compare trials with similar loading, openings and dwell time. One parking example does not prove general equipment performance.
Decide by transport type. An insulated carrier provides passive protection using a prepared cold source's heat capacity; a reefer controls conditions with energy and an operating unit. Follow product procedures on outage or deviation.
