AMAX II Stage Cooling System

AMAX

Introduction 2 Types of Air Conditioning Systems Air conditioning Evaporative Mechanical Direct II Stage Compressor Water/Air Cooled Condenser

Introduction II Stage Evaporative Cooling Concept since 15 years Added Indirect Stage & Cooling Tower to Conventional Evaporative Cooling & Adiabatic Efficiencies increased from 80% to 115% of II Stage Lower Temperatures / Controlled Humidity Greater Comfort Control Hence can now also be used for Specialized Applications

Concept Understanding II Stage Evaporative Cooling Contd.. Stage I Air Stream not in direct contact with Wet Medium Temperature Drop with no addition of Water Vapour to the Air Stream.

II Stage / Indirect-Direct Evaporative Cooling Stage II Addition of Water Vapour to the Air Stream & further lowering of Temperature using rigid media II Stage I Stage COOLING

Concept Understanding Requirements for Effective use of II Stage Cooling Natural Temp to have large Wet Bulb Depression Designing to be same as Ventilation i.e. 25 to 40 air changes per hour below the grill.

AMAX COOLING PROCESS A NEW UNIQUE COOLING PROCESS STAGE ONE: - Indirect cooling coil removes sensible heat from the primary supply air stream providing 70-75%Indirect saturation efficiency. Direct evaporative cooler produces near adiabatic cooling, resulting in a total two stage saturation efficiency of 110%-115%. STAGE TWO : And hence the Comfortable, Healthy, Cooling

RELIEF COOLING TEMPLATE

RELIEF COOLING TEMPLATE Nomograph for the rapid calculating of direct evaporative cooling results. The two templates show the nomographic procedures for comfort cooling maintaining indoor dry - bulb 8 o F below outdoor air, and for relief cooling with a 6 o F differential. In both cases comfort sensations depend heavily upon air velocities. Adapted from early ASHRAE effective Temperature nomographs for comfort determination.

RELIEF COOLING TEMPLATE Calculating Rough Direct Evaporative Cooling Comfort Levels. 1. Select ODB and WB from local air conditioning design data. ODB is Outdoor Dry Bulb temperature. WB is Outdoor Wet Bulb temperature. 2. Draw Outdoor Condition Line from ODB to WB 3. Select Cooler Saturating Efficiency column. Where it Crosses Outdoor Condition Line. Read WAE, the washed air room entering temperature. 4. Select washed air Indoor temperature gain, usually 6 o to 10 o F, and WAE, and draw a line to WAE, exhaust temperature. 5. Locate WAIA, the washed air Indoor average temperature, midway between WAE and WAX.

RELIEF COOLING TEMPLATE 6. Draw horizontal line left from WAIA to find IDB, the average indoor dry bulb temperature. 7. Select IWB (Not shown), usually 2 o F above WB. It is the estimated indoor wet bulb temperature. 8. Draw indoor Condition Line from IDB to IWB. 9. Select an estimated indoor average Air Velocity Line in grid at left, usually between 100 and 400 fpm. 10. Read indoor comfort level in Effective Temperature degrees, where Indoor Condition Line crosses indoor Air Velocity Line. Read estimated present of comfortable people at upper left.

Wind Chill Effect as per ASHRAE Comfort Chart Adaption to other Conditions Aside from its fixed dew point limits, the ASHRAE Comfort Zone adjusts for faster indoor air velocities and for human acclimatization to conditions. First, the zone expands to tolerate higher dry bulbs; its right hand border moves to the right as circulation rates increase to about 350 fpm (1 8 m /s). Assuming the taller zone noted above, it allows some conventional direct evaporative cooling to achieve official comfort.

Wind Chill Effect as per ASHRAE Table IV 2 AIR MOTION AND COOLING SENSATIONS Average Air Velocity Around Persons Miles per Feet per Meters per Effective Degrees of Hour Minute Second Cooling Achieved.1 8.8 0.045 -----.5 44.0 0.224 5.0F 2. 1.0 88.0 0.447 7.0 3.9 2.0 176.0 0.894 9.7 5. 4 3.0 264.0 1.34 10.3 5.7 5.0 440.0 2.24 11.3 6.3 10.0 880.0 4.47 12.6 7.0 Second, other extension areas appear on the zone right border to represent comfort felt by persons acclimated by 7 to 10 days exposure to moderate discomfort. After initial habituation, mere one day per week re-exposure maintains the benefits. Specifically, the right-side extension approximates 2 o F (1.1 o C) ET*, presumably additive to velocity based extensions.

What to do to decide on Which System to Use 1. Get the t temperature & RH of your AREA TO COOL Summer Wise. 2. Decide a practical temperature that you need for your application & why. 3. Inform the concerned department person etc of the same when asking for a design Quotation.

Which System to use Check Total Cost of system i.e. unit cost, cabling, transformers, panel board, deposit to electricity dept., generator cost, AMC etc. - Compare Running Cost of all for approx. 3 year of running.

SMART CONDITIONING CONCLUSIONS 1. The AMAX is a Healthier considering we are using 100% Fresh CLEAN Air. solution 2. With AMAX, all Stale Air, Fumes, Odour are removed from the conditioned area. 3. Humidity levels are controlled & much lower than conventional units.

SMART CONDITIONING CONCLUSIONS 4. The AMAX is an Economical solution considering that it consumes 24% of the power 5. The AMAX is an Ecologically sound decision as there are no CFC s involved 5. The AMAX is a Green decision as it is nature s s own way of cooling 6. With AMAX Carbon Credits can be claimed

SMART CONDITIONING CONCLUSIONS ONLY 2 TYPES OF PEOPLE WILL USE THIS TYPE OF AIR CONDITIONING i.e. The Intelligent alternative for AIR CONDITIONING AMAX 1. Health conscious people / Industries 2. Cost / Energy conscious people /Industries
