Schinella's - Preserving Food Quality
Elevating customer comfort while preserving food quality at the iconic Schinella's fresh fruit, vegetable, and specialty market.
Schinella’s Your Local Market in Prospect, SA, is a well-known family-owned destination for fresh produce, specialty groceries, and an authentic market experience. Maintaining optimal conditions for both shoppers and perishable products is critical to the store’s reputation and operational success.
To align with their values of quality, sustainability, and customer comfort, Schinella’s turned to Seeley International’s Climate Wizard CW-H15 Indirect evaporative technology to provide an energy-efficient, all-electric HVAC solution for standalone and supplementary cooling, ensuring fresh air, controlled temperatures, and reduced energy consumption throughout the year.
Project Requirements
The primary goals of the project were to:
- Deliver 100% fresh, filtered outside air to maintain indoor air quality for both shoppers and staff.
- Provide energy-efficient cooling performance without relying on conventional refrigerated systems.
- Control internal temperatures for both customer comfort and to support the longevity and quality of fresh produce.
- Ensure moisture-free cooling, avoiding humidity build-up in the store.
- Minimise power consumption and reduce operational costs, without compromising performance.
Proposed Solution
To meet the unique environmental and performance needs of the market, four Climate Wizard CW-H15 indirect evaporative coolers were installed, operating in standalone mode.
Key Performance Details:
- Total Airflow: 4,400 L/s
- Supply Temperature: 17.2°C (Ambient: 38.1°C DB / 19.1°C WB)
- Standalone Cooling Capacity: 54.3 kW
- Coefficient of Performance (COP): 7.5
- Total Units: 4 x CW-H15
