The kitchen has one exhaust fan with one supply fan operating with a VSD (Variable Speed Drive). RSS (Remote Start Stop) has not been selected so the TRUFLOW will operate locally. KES has not been selected so the fan is a straight exhaust with no Kitchen Enviro System selected. In addition there is no WASH selected so there is no automatic wash type hood connected to this kitchen. Spring Air Systems TRUFLOW Engineering Manual December 2007 2
What is TRUFLOW? The TRUFLOW Energy Management Controller has been designed to change kitchen exhaust forever. TRUFLOW will automatically reduce the exhaust and supply air into the kitchen whenever appliances are not used at full capacity. When the appliances are not used and the heat is turned down or off TRUFLOW automatically senses the reduction and decreases the amount of exhaust and supply to match exactly what’s happening under the exhaust hood. The TRUFLOW duct mounted J-Couple monitors the exhaust temperature, which fluctuates based on the amount of appliances operating under the exhaust hood. As the amount of cooking increases the exhaust duct temperature rises and reaches an equilibrium temperature during each hour of the day. This equilibrium temperature represents a percentage of total cooking capacity. The 30% utilization temperature may be 80F. The 70% utilization temperature may be 105F. The duct temperature could reach as high as 150F and as low 75F depending on the following factors: • Kitchen room temperature • Total exhaust volume • BTU rating of each appliance • Total volume of makeup air • Temperature of makeup air • Where the makeup air is introduced back into the kitchen • Type of hood over the appliance TRUFLOW automatically modulates the exhaust and supply to suit the actual cooking operation at any given time during the cooking day. Why Use a TRUFLOW? Energy Savings up to 55% annually! Reduces operating cost. Let’s take a look at Chart No 1. The TRUFLOW does not lower the exhaust volume below 30% of the maximum operating exhaust. For the purpose of this chart we add operating times below 30% into the 30% operating time. Appliance Operating Capacity % of full appliance load that kitchen is operating at Operating Time % of time that kitchen is operating at stated Appliance Operation Capacity Hours of 16 hour day Number of hours, out of a 16 hour day, equating to % shown in Operating Time Equivalent CFM Calculated as Total Exhaust CFM x (%Appliance Operating Capacity) x (%Operating Time) Based on 4500 CFM total exhaust volume from our example above, the chart is tabulated.
