Innovative Solutions to Improve Comfort & Efficiency NEX and PLAY Slide 2 Discomfort is Expansive Slide 3 Office Building Average HVAC technician service call: $400 Absenteeism Decreased employee performance Cost of over heating and over cooling Extreme cases of losing employees: cost of re- hiring, re-training, loss of productivity Slide 4 What about a restaurant? Slide 5 Seating capacity: 300 Open 360 nights / year Average 1 dinner / seat / night Total 108,000 customers / year Some feel air distribution-related discomfort 2% of customers would've stayed a bit longer if slightly more comfortable, just enough to buy one last drink or dessert Average gross profit per drink or dessert: $3 Slide 6 Seating capacity: 300 Open 360 nights / year Average 1 dinner / seat / night Total 108,000 customers / year Some feel air distribution-related discomfort 2% of customers would've stayed a bit longer if slightly more comfortable, just enough to buy one last drink or dessert Average gross profit per drink or dessert: $3 $6,840 profit / year Consequence: Slide 7 Common sources of air distribution related discomfort Slide 8 A well designed HVAC System Performs really well in theoretical or average conditions Slide 9 Cold air supplied at low velocity... Will drop from standard diffusers Slide 10 While at higher velocity... Air jets collide and are deflected Slide 11 How can we improve performance in VAV applications? Using a diffuser providing higher tolerance to velocity and temperature variations. Slide 12 NEX Concave Elements Won a new products contest as the Best Heating Component Also ideal for cooling and VAV applications Innovative architectural look Slide 13 NEX Concave Elements Swirl pattern Air diffused in multiple jets of various velocities High induction ratio, mixes more air, faster and more evenly Higher tolerance to temperature and velocity variations Slide 14 Slide 15 Slide 16 Another very common issue causing discomfort Flex duct with kink or angle Up to 80% of airflow could be diffused in one direction Same issue with rigid duct and 90 degree elbows Slide 17 In theory, ASHRAE recommends Rarely happens in real world Most of the time, not enough space in the ceiling Sometimes installer just lazy, poorly trained or trying to save on time and material Slide 18 NEX + PERFAIR 2 layers of air equalizing First layer: damper + equalizer integrated in plenum's neck Second layer: the Concave Elements. No direct exit, air is forced to swirl inside the plenum Slide 19 Energy Efficiency Stratification & uneven mixing of supplied air with room air causing inaccurate or varying measurements of thermostat and humidistat Can result in over-heating / over-cooling Equipment on/off and modulation = more energy used to achieve same result as steady conditioning Slide 20 Return on Investment An HVAC system is a chain of components A chain is only as strong as its weakest link Cost adds up... Not Performance! Slide 21 What about unpredictable factors? At design time, impossible to know and plan for everything Added furniture and decorative objects might obstruct and deflect air jets Cubicle layout modified Each individual's tolerance to hot and cold Slide 22 Solutions available so far Blocking air in one or more directions Air volume control damper Adjustable diffusers, from horizontal to vertical airflow VAV diffusers, expansive to purchase and to install Slide 23 The new solution Slide 24 PLAY Adjustable Sectors Only diffuser allowing for full horizontal adjustment Easy to adjust, from the face and without tools 1, 2, 3, 4 way and swirl with easy sectors positioning Can also be adjusted by as many degrees as required to avoid people and objects Innovative architectural look Slide 25 Example 1 - Cubicle Layout 7/8 comfort ratio 1 person complains about the cold Slide 26 Solution 1 : adjust damper to reduce the volume of cold air supplied 5/8 comfort ratio Slide 27 Solution 2 : block one way 5/8 comfort ratio Slide 28 Solution 3 : block one way + adjust damper for less volume 7/8 comfort ratio Slide 29 PLAY Solution: adjust horizontal angle just enough to fix issue 8/8 comfort ratio Slide 30 Slide 31 From Above Slide 32 Solved the comfort issue... In the most energy efficient way Slide 33 PLAY Adjustable Sectors Gives flexibility to quickly solve air distribution issues Fewer and cheaper service calls Increased general level of comfort Can help optimizing energy Just PLAY with it! Slide 34 PLAY-R New design possibilities Slide 35 Horizontal spread in narrow spaces Slide 36 Hallways Blends in perfectly while supplying air efficiently Slide 37 High tolerance to velocity and temperature variations Not affected by angle of air entering diffuser High Induction Rate Great for limited space in the ceiling Choice of 5 Concave Element colors NEX - Reliability Slide 38 PLAY - Flexibility High tolerance to velocity and temperature variations Not affected by angle of air entering diffuser High Induction Rate Great for limited space in the ceiling Choice of 5 Concave Element colors Optimize Comfort and Energy Only diffuser allowing for full horizontal adjustment Easy to install, easy to use New design possibilities Save money on first service call NEX - Reliability Slide 39 PERFAIR plenums with Top or Side connexions PLAY - Flexibility High tolerance to velocity and temperature variations Not affected by angle of air entering diffuser High Induction Rate Great for limited space in the ceiling Choice of 5 Concave Element colors Optimize Comfort and Energy Only diffuser allowing for full horizontal adjustment Easy to install, easy to use New design possibilities Save money on first service call Suitable for all types of ceilings (Lay-in, Drywall, Open) NEX - Reliability Both can easily replace diffusers in existing buildings Slide 40 You now have the option! effectiv-hvac.com NEX and PLAY Innovative Solutions
