  1. Use of Polyisocyanurate Rigid Board & Displacement Ventilation www.yitac.com.sg

  2. HELLO! I am Remond Bey I am here because I love to give presentations. You can find me at www.yitac.com.sg

  3. WHAT IS POLYISOCYANURATE? It is said to be also polyiso which is a thermoset plastic that can be produced as a foam and they are used as rigid thermal insulation. The materials that are used in it are in the proportion of methylene diphenyl disocyanate which is higher, and they are polyester-derived. www.yitac.com.sg

  4. HOW IT GET MANUFACTURED? The reaction between the MDI and polyol usually takes place at higher temperatures which were compared with the reaction temperature which are generally used for the manufacturing of PUR. At the temperature and in the presence of specific catalysts, MDI will first to react with itself, and then it will produce the stiff, ring molecule and it is a reactive intermediate polymer. www.yitac.com.sg

  5. BENEFITS • Keeping the outside air away • Help in blocking the pollen, dust particles and other contaminants • Lowering the energy use and cost • Used in both interior and exterior due to the good design and function Before you go for the Polyisocyanurate Rigid Board, you need to see these things. www.yitac.com.sg

  6. USES OF POLYISOCYANURATE • Used as rigid thermal insulation, and it acts as thermal conductivity • Used for fabrication of the pre-insulated duct heating, air conditioning systems, and ventilation. • Usedin roofing insulation and vertical walls www.yitac.com.sg

  7. What Is Displacement Ventilation It is a system in which the concept of displacement ventilations and the air which is supplied is at a low temperature when it comes about the air. This air is said to be supplied at floor level, and it is directed to the occupied zone. www.yitac.com.sg

  8. Designing of VENTILATION When DV is applied, the ventilation rate and the cooling load density was ensured so that the cooling requirements will be aligned with the supply of the air system’s ability which will offset the gain of heat. These temperature based design can be used to match the supply temperature along with the current load in the space. www.yitac.com.sg

  9. ADVANTAGES • It provides the better air quality which is mixed-flow systems. • It got low supply velocity at its diffusers which means it will be a low-pressure drop. • It can use less ductwork. When you are going for the Displacement Ventilation, you need to know about the things that are important. www.yitac.com.sg
