Evaporator Located Inside The Showcase Upper Area

Evaporator located inside the showcase upper area

In commercial refrigeration systems, such as display showcases or refrigerated display cases used in supermarkets and convenience stores, the evaporator is often located inside the upper area of the showcase. This placement is common in vertical display cases or upright refrigerated units and serves several purposes:

1. Optimal Product Cooling: Placing the evaporator in the upper area allows for even cooling throughout the entire showcase. Cold air is distributed downward from the top, ensuring that all products inside the case receive consistent cooling. This arrangement helps maintain a uniform temperature and keeps perishable items at their required storage temperatures.

2. Reduced Product Drying: When the evaporator is in the upper section, it minimizes the direct contact between the cold air and the products on the lower shelves. This can help reduce the drying effect that cold air can have on certain products, such as fresh produce, by limiting direct exposure to cold air currents.

3. Enhanced Visibility: Placing the evaporator in the upper area of the showcase allows for a clear, unobstructed view of the displayed products. This is especially important in retail settings where customers need to see and access items easily.

4. Efficient Air Circulation: The cold air generated by the evaporator flows downward naturally due to the principle of convection. This natural air circulation helps maintain temperature consistency and reduces temperature stratification within the display case.

5. Energy Efficiency: By allowing cold air to descend naturally, the placement of the evaporator in the upper area can contribute to energy efficiency, as it may require less energy to circulate cold air compared to a system with the evaporator located at a different level.
