Adaptive Frequency

Drive

The largest energy user in most buildings

is the chilled water system. The RTHD Adaptive

Frequency Drive, from Trane Care Energy Services,

can make significant savings in the energy

consumed.

Trane Chiller VFD

Adaptive Frequency Drive Overview

A powerful upgrade that

delivers

1.Precision control

2.Energy efficiency

3.Lower utility costs

4.Noise reduction

5.Longer equipment life

Performance

Up to 35% better energy efficiency at all load points

Trane AFD reduces electricity bills by improving chiller

efficiency at reduced load, while at same time meeting

the building’s cooling requirements. The combination

of Trane chiller capacity control and Adaptive

Frequency Drive will improve chiller efficiency up to

35%.

Benefits

Benefits

• Low load capability

• Unloading capabilityRTHD : 20%

RTHD AFD: 12%

Reduces start-stop cycles by enabling the chiller to

operate at lower capacities.

For chiller operating at low loads (comfort application)

stop/start will be reduced by ~45%

Benefits

Benefits

• Lower inrush current

• Starting current reduced by 5

Helpful for application experiencing

disruption when starting many electric

devices at same time.

Starter type Inrush current (% Imax)

Direct in line 600 - 800%

Wye Delta 200 – 275%

Solid State 300 - 500%

AFD <100%

Maintenance in existing Air- conditioning system for better Efficiency

Air Handling Unit:• Cooling Coil efficiency – by cleaning with proper cleaning

agent at regular interval. Use of UV light to reduce bacteria growth in the coil.

• Fan efficiency

Cooling Tower (for water-cooled system)• Proper spray of water

• Clean of fills

• Proper adjustment of fan blades.

• Use of water bleed off for circulation water

• Only soft water to be used for make up to reduce fouling in the condenser .

Energy Consumption Trend

Remarks– New MRI machine installed increased 750 kw / month of load, our

energy conservation effectively neutralizes the upward consumption trend.

ENERGY MEASUREMENT,MONITORING & REPORTING

•Dedicated energy Meters for all the panels

•Separate energy meters for lighting, HVAC

•Record of daily energy meter recording

•Annual calibration of all energy meters.

•Monthly review of energy balancing by energy

Management Cell

Waste Reduction

• Mixture Tap nozzle fixed in OPD area washroom to reduce the waterconsumption approx 500 KL monthly

• Hand Dryier fixed in OPD wash room to reduce the paper consumption upto 15 %

• Paper saving by Using both sides of paper while printing also reuse old papers for inter office work.

• X-Ray films eliminated using PACS systems through IT.

• On line soft wares are used for office work like oracle, my Fortis,out look, Patient Portal ,QMS etc. Resulting saving of papers

Implementation on Energy, Water & Environment

BY maintaining of Power factor above 0.99Regular de-dusting of lighting fixture.Cleaning of filters in air conditioning system.Maintaining the optimum voltage of lighting systemSwitching off lights/monitors/AC when not in use.Use of high –efficiency fixtures (water closet & urinal) to reduce the potable water demand.Raw and treated sewage quality monitoring on daily basis and Quaterly report to be submit to DPCC. water meter to be measured on daily basis for the water consumption control. Conducting Daily inspection walkthroughs for identification of any water losses.Use of separate storm , sewage and oil water separators drainages to avoid ground water contamination.Celebration of Environmental day, Engineers day etc.
