CAT 1600-2 • MODEL AV UNIT VENTILATOR

Introduction Precise Temperature and Dehumidification Control Daikin Classroom Unit Ventilators For nearly a century schools have relied on unit ventilators to keep classrooms comfortable. Students learn more readily in a quiet, well-ventilated environment. That is why Herman Nelson invented the unit ventilator in 1917. Daikin Applied continues to set the industry standard for performance, features and quality. Today Daikin remains committed to continuing the Herman Nelson-AAF-McQuay legacy as the industry leader and meeting the changing requirements of schools with the highest quality unit...

Introduction The Model AV is just right for new construction and for retrofit applications. Older buildings with baseboard radiant heat or other hydronic heating systems can be easily adapted to work efficiently with Model AV units. Chilled-water or refrigerant cooling can be added to provide year-round comfort. The major features of this model are shown below and described in more detail on the following pages. Model AV Floor Unit Features Our Model AV is a vertical, floor-standing unit that utilizes remotely-supplied chilled water or refrigerant for cooling, and hot water, steam or...

Features & Benefits • A large, expanded discharge opening minimizes air resistance, further lowering sound levels. • Precision tolerances help reduce flow and pressure turbulence, resulting in lower sound levels. • Fan housings incorporate the latest logarithmic expansion technology for smoother, quieter air flow (Figure 1). • Modular fan construction contributes to equal outlet velocities and promotes quiet operation. • Fan shafts are of ground and polished steel to minimize deflections and provide consistent, longterm operation. • Fan assemblies are balanced before unit assembly, then...

Features & Benefits The Right Amount of Fresh Air and Cooling Part-Load Variable Air Control Daikin unit ventilators deliver required amounts of fresh air to meet ventilation requirements and added cooling capacity to maintain consistent comfort for students and teachers. Our Economizer Operation, Demand Control Ventilation (DCV) and Part Load, Variable Air options allow you to match classroom comfort requirements even more closely, and reduce operating costs. This means that you can be confident that your school is meeting ventilation standards for Indoor Air Quality and that your students...

Features & Benefits Precise Temperature and Dehumidification Control removal. Humid outdoor air is not bypassed around the coil until the total amount of cooling air required is less than the total amount of fresh outdoor air required in the room. Figure 5 and Figure 6 below compare the composition of the air streams through the coil and air streams bypassing the coil at various bypass air percentages for draw-thru and blow-thru unit ventilators using 450 cfm of outdoor air. At both 0% bypass air and 100% bypass air, no difference exists in the composition of the air streams. However, at...

Features & Benefits This illustrates that the most effective way to maintain an acceptable humidity level with a chilled-water unit ventilator system is to use a face and bypass damper, draw-thru unit. Why Blow-Thru Designs Don’t Measure Up Blow-thru designs cannot provide comfort like this. With blow-thru designs, the humid outside air is pre-mixed with the room air before it can go through the coil (Figure 7). Dehumidification occurs only to the portion of the air that is directed unevenly through the cooling coil. The air that bypasses the coil is largely humid outdoor air, resulting in...

Features & Benefits Low Installation Costs Daikin unit ventilators have many features that make them economical to purchase and to install in both new construction and retrofit applications. It is this attention to detail and understanding of school applications that make them the system of choice. Perfect For Both New & Retrofit Applications New construction installations are easily accomplished with Daikin unit ventilators because they avoid the added cost and space required for expensive ductwork. Further savings can be realized because piping installations use less space than duct...

Features & Benefits Low Operating Costs Schools consume more than 10% of the total energy expended in the United States for comfort heating and cooling of buildings. As energy costs increase, educators are placed in a difficult position: caught between rising costs, lower budgets and the requirements to raise educational standards. Fortunately, the technology and the system exists for schools to take control of their energy expenditures while providing a comfortable environment for learning. And that system is the Daikin Applied unit ventilator. Consider these realities of school...

Features & Benefits Heavy-Duty Discharge Grille Daikin Unit Ventilators are designed to provide easy access for maintenance and service personnel to all serviceable components. Most maintenance tasks are easily handled by a single person. The discharge grille on the top of the unit is made from extra-strength steel bar stock, promoting long life (Figure 13). It can be removed to facilitate cleaning of fans and fan housings. A built-in 10-degree angle provides proper air throw to blanket the room for proper air circulation and comfort. Modular Fan Deck The entire fan deck is easily removed...
