HVAC Case Study
Schinella's - Preserving Food Quality

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
• Moisture-free cooling year-round delivery of cool air with no added humidity

System Benefits:

• 71% reduction in power demand compared to an equivalent refrigerated system.
• Estimated energy savings of 34,000 kWh annually, contributing significantly to Schinella’s sustainability efforts.
• Improved shelf life for fruits and vegetables due to stable, low-humidity air, reducing spoilage and enhancing product quality.
• Fresh air advantage improves the shopping experience, eliminating stale or recycled air.
• Helps maintain odour-free, well-ventilated conditions across the market floor.

The Outcome

The Climate Wizard installation at Schinella’s Prospect market has delivered tangible results:

• Enhanced Indoor Air Quality

Shoppers and staff enjoy a noticeably fresher, more comfortable indoor environment, with 100% outside air circulation, supporting health and wellbeing.

• Optimised Food Storage Conditions

Fresh produce, bakery goods, and other perishables benefit from temperature-stable, dry air conditions, helping extend shelf life and reduce waste.

• Significant Energy and Cost Savings

By shifting away from traditional refrigerated cooling, Schinella’s has achieved a 71% power saving and projected annual energy savings of 34,000 kWh, significantly reducing their carbon footprint and operational costs.

• Reliability in Performance Year-Round

Even during South Australia’s peak summer temperatures, the system delivers consistent 17.2°C supply air without adding moisture, keeping the market cool without compromising on efficiency.
