A Thing That Contributes to Civilization Advance

It is our manifest destiny to deliver and pass around good things. Youone International or YOIUSA is a Texas reseller of HVAC solutions made in North America. Clients are mostly exporters situated in Southern California and, internationally, Asia Pacific. Area of interest is how to stay connected, comprehend and deliver value. In between supply and demand, we maximizes leads and close sales by myriads of interaction with concentrated exposure to user-end interests.

It is matter of survival. Traditional industry to include  EPC (engineering, procurement and construction) and ESPC (energy saving performance contracting) is undergone for digital transformation. Digital deals with numbers and devices that collect, transport and distribute numbers that contain certain logical context. Did you know by lowing fan speed in half, power use can be lowered to 0.125, and as low as 0.25 m/s air movement entrained in every single corner of your space may help in turning fan speed down by half? Believe or not, it is true while real world story may be different.

The thing is if your vav is working as such and if you care about it. Digital may be another way of making things happen by giving signals in a different way and a way to give improvement of efficiency. Again, the question is if you care about your vav going digital and know what does it take to turn your vav to be digital. No matter what you are doing, YOIUSA may be worth trying to work with to care about your vav and deal with digital things mechanically together.

An overhead variable air volume (VAV) diffuser called Thermafuser may help define and characterize a HVAC system performance in various ways as required. This device uses neither motor nor pneumatic activation as power source. This product is thermally powered using phase change material fine-tuned in California. COANDA is featured as well in geometry of product. Housing is pressed by over 250 ton one-punch deep drawing for shallow curve on ridge. Vena Contracta is provoked by jet nozzle structured for powerful entrainment of secondary air toward primary to mix well within 0.6 meter of throw from discharge tip of damper blade. These work for even distribution of supply air for better PMV performance.
