In immediately’s energy-conscious world, industries and industrial services are consistently searching for methods to cut back HVAC vitality consumption whereas sustaining consolation and air high quality. Handled Recent Air (TFA) items, that are essential for sustaining indoor air high quality by introducing filtered and conditioned out of doors air, are sometimes accountable for a good portion of an HVAC system’s vitality utilization—particularly in scorching and dry climates. One progressive and efficient technique to improve the effectivity of those programs is by integrating Oblique Evaporative Cooling (IEC) modules for pre-cooling the incoming recent air.
What’s Oblique Evaporative Cooling?
IEC is a course of that cools air with out including moisture. Not like direct evaporative cooling, the place water is added on to the airstream, IEC makes use of a Polymeric plate warmth exchanger to chill the first air with separate stream of water & air which travels in adjoining Channel . This course of leads to temperature discount with out growing humidity—making it excellent for purposes the place moisture management is vital.
How IEC Modules Improve TFA Unit Effectivity
Right here’s how IEC modules make a distinction when built-in with TFA items:
- Pre-cooling the Recent Air Load
Outside air is commonly scorching and dry, notably in areas with arid climates with excessive smart hundreds. IEC modules can carry down the temperature of this incoming air by 7–12°C earlier than it reaches the mechanical cooling coil. This considerably reduces the load on the DX or chilled water coil contained in the TFA unit.
- Vitality Financial savings
By reducing the temperature of the consumption air and eradicating the smart load , the mechanical cooling system operates beneath lighter hundreds, lowering electrical energy consumption. In lots of instances, vitality financial savings of 20–30% will be achieved relying on the ambient situations and system design.
- Decrease Peak Load Demand
IEC-assisted AHU programs can considerably scale back peak energy demand, easing pressure on electrical infrastructure and lowering utility payments—particularly in industrial buildings and manufacturing services with giant HVAC programs.
- Longer Tools Life
With decreased compressor load and decrease wear-and-tear on chillers and AHUs, the general lifespan of HVAC parts will increase.
- Sustainable Cooling
Since IEC depends on water and ambient air slightly than refrigerants and compressors, it’s a greener different and helps in assembly sustainability and ESG (Environmental, Social, Governance) targets.
Typical Integration in a TFA System
- The IEC module is put in forward of the first cooling coil within the TFA unit.
- Recent air first passes by the IEC warmth exchanger, the place it’s pre-cooled.
- The already cooler air then strikes by the traditional coil for any additional vital conditioning.
- This hybrid method ensures the recent air delivered indoors is energy-efficiently cooled with out compromising air high quality.
- Retrofitting an current air dealing with unit /Recent air dealing with unit / handled recent air unit can be potential.
Functions of IEC-Built-in TFA Models
It is a wonderful improve over standard TFAs and vitality restoration wheels and extensively utilized in varied manufacturing items:
- Industrial buildings with giant air flow necessities
- Pharmaceutical manufacturing and cleanrooms
- FMCG Models
- Meals & Drinks items
- Glass & glass tools manufacturing unis
Metal industries – in cooling of panel / server rooms
