The Challenge

Supermarket
Reducing Water Reliance of CO2 Systems

A supermarket in Northern California designed its CO2 refrigeration system with an adiabatic gas cooler to protect against the sudden, extreme heatwaves occasionally experienced in the region. Given the area’s moderate climate, the adiabatic system was rarely needed, with temperatures exceeding 75°F (24°C) for just 167 hours in 2023. Despite its infrequent use, it still provided peace of mind on hot days. The supermarket began looking for a solution that could maintain their system efficiency while reducing water costs.
