Question

How is a smoke candle used when troubleshooting an open display case?

Answer 1

A smoke candle is used to observe air flow patterns in an open display case by introducing smoke and noting its movement.

Step-by-step explanation:

A smoke candle can be used when troubleshooting an open display case to determine the air flow patterns within the case. By introducing smoke from the candle into the case, the student can observe how the smoke moves and identify any areas where there may be a lack of air circulation.

This can help identify the cause of an open display case not cooling properly or items within the case not being adequately cooled. For example, if the smoke from the candle is stagnant in certain areas, it may indicate a blockage or malfunctioning fan.

Overall, using a smoke candle provides a visual representation of airflow and allows for troubleshooting and identifying issues within an open display case.

Answer 2

Smoke candles are used to identify airflow patterns and leaks in an open display case by observing the behavior of emitted smoke, which is critical for maintaining the case's efficiency and protecting the displayed goods.

Step-by-step explanation:

A smoke candle is commonly used to visualize airflow patterns and detect leakage in various systems, including open display cases often found in retail environments to showcase and preserve perishable goods. The use of a smoke candle in troubleshooting an open display case involves igniting the smoke candle and placing it in strategic locations around the case.

As the smoke is emitted, observations can be made regarding the flow of smoke, which helps to identify potential air leaks, improper sealing, or issues with ventilation within the display case. This method is essential to ensure optimal functioning of the display case and to maintain the appropriate temperature and humidity levels for the products displayed.

During troubleshooting, it is important to record observations carefully as this information is critical to making the necessary adjustments to the system. For instance, if the smoke is drawn into the display case rather than flowing smoothly around it, this indicates possible air ingress. Resolving these issues ensures the display case works efficiently, thereby protecting the goods and saving energy.
