2 2 about us ABOUT THE COMPANY MINIB ranks among the leading manufacturers of HVAC systems in the Czech Republic. It currently exports its products to more than thirty countries in Europe, Asia, Australia, and America. Since 1999, MINIB has been systematically innovating production technology and its products, and it invests quite considerable amounts in its own development and design, with the goal of offering its customers advanced technical and aesthetic solutions. MINIB is an economically stable company which has been consistently generating profit. CERTIFICATION Our company is a holder of a quality management certificate, ISO 91:29 for the field of design, development, manufacturing and sale of heating and cooling s. The entire product portfolio is tested in an independent accredited testing chamber, which allows us to guarantee the stated heating and cooling output values. Our company is also a holder of numerous utility models and patents. ABOUT THE MANUFACTURING PROCESS The manufacturing facility is located in Býkev near Mělník, and has excellent road connections. It is furnished with state-of-the-art manufacturing technology. Most manufacturing operations are carried out on CNC machines, which allows us to meet even the most sophisticated requirements of our demanding customers. All products are made only from high-quality materials with long life cycle, which allows us to offer ten-year warranty on the heat exchangers. contents INDUCTION UNIT DESCRIPTION Basic information 3 Induction principle 4 Induction benefits 4 CALCULATION OF THE INDUCTION UNIT PARAMETERS Definition of parameters 5 Inlet water temperature when cooling 5 Cooling output for selected conditions 6 Heating output for selected conditions 9 POSSIBLE CONNECTIONS TO HVAC Basic dimensions of the 12 Dimensions for water inlet and outlet 13 Dimensions for air inlet 13 Overview of all versions of the 14 Induction ordering code 14 FLOW SPEED CHARTS 15 UNIT INSTALLATION Method and close-up view of the mounting 18 Spacing of holes for suspension of the from the ceiling 18 Methods of installation 19 Maintenance of the 19

3 description 3 BAsIc InFoRMAtIon Induction s are modern devices based on a water to air system, which makes it possible to efficiently change the temperature of the air and to distribute it silently with minimal energy requirements. An does not contain a fan; it functions by way of entraining the primary air through nozzles, driven by the induced injection effect drawing the secondary air to the room. This principle is explained in more detail in the next chapter. The primary air is centrally treated fresh air from outside, which is distributed by HVAC ducts to the s installed in the ceilings of the rooms concerned. The secondary air is the air in the room that is drawn in through a heat exchanger within the ; the secondary air is cooled by the heat exchanger when the cooling function is on, and heated by the heat exchanger when the heating function is on. In the case of cooling, it is necessary to ensure correct design of the temperature of the cold water supplied, so that the dew point is not reached, which would lead to condensation of the air humidity. Optimal mixing of the primary and the secondary air occurs in the. The cooling or heating output, to cover the thermal losses or gains, is therefore provided by the change of the condition of the secondary air, using a water to air heat exchanger and also by the supply of the centrally treated primary air. The troughs metal parts and grilles are made of galvanized sheet metal. The visible surfaces of the trough and grilles are painted white as a standard design. The can also be supplied in different colours, depending on the end user s request. The pipes for the water supply and the drain are made of copper. The grille is removable and secured with a steel wire to prevent it falling down when removed for service. Water inlet primary air inlet Water outlet Unit frame removable grille Unit hanger

4 4 description InDUctIon UnIt PRIncIPLe Induction s, also known as active cooling beams, are connected to the distribution system for external treated air, the primary air. The primary air is pushed under through nozzles behind which the ejection effect takes and sucks in the secondary air from the room. This suction of the secondary air from the room occurs through a heat exchanger where the air is cooled or heated. The primary and secondary air is mixed inside the, and the mixed air is subsequently distributed to the room. This takes place inside the.

As the temperature of the water supply must be above the dew point, it is not necessary to remove the heat exchanger during regular maintenance. We recommend removing the removable cover once a year and removing the contamination, if any, from the inner parts of the. SAFETY WIRE
