Master Touch refrigerated storage project is a 45,000 sqft refrigerated warehouse space used for storing imported fruits and vegetables. The space consists of 5 different cooler rooms. The design consists of refrigeration units for each cooler. to ensure an energy efficient operation of the space, insulation calculations for the walls, floors and ceilings of each cooler were provided . Because of the quantity of refrigerant in the refrigeration system, special exhaust and ventilation calculations were provided to ensure safe operating conditions. Plumbing design for this project was limited to a new floor sink for the condensate drainage of the fan coil units. Because of the size and type of refrigeration units, and refrigeration that were provided, close coordination with CARB and EPA was required to ensure the project was compliant at all levels.
