 ALTERNATIVE TO ELECTRIC
     DRIVEN CHILLERS

• LPG/LNG
• STEAM
• HOT WATER
• WASTE HEAT
• SOLAR
 INDUSTRIAL PLANT PROJECT


• FOOD PROCESSING PLANT
• USES STEAM FOR MAIN
  PROCESS AND PRODUCTION
• REQUIRES COOLING OF
  CHEMICAL TANKS USING 165
  RT RECIPROCATING CHILLER
  PROJECT OBJECTIVES


• REDUCE OPERATING COST
 – PHP 6.50/KWHR
• REDUCE ELECTRIC GENERATOR
  LOAD
 – FREQUENT POWER FAILURE
PROJECT EXECUTION

1. REPLACED 165 RT ELECTRIC
   CHILLER WITH STEAM FIRED
   ABSORPTION CHILLER RATED AT
  4.8 KG/RT
2. INSTALLED NEW ABSORPTION
  CHILLER RATED AT 3.8 KG/RT
   RECIPROCATING VS ABSORPTION

  RECIPROCATING             ABSORPTION 4.8kg/rt

Power input = 132 kw        Steam input= 792 kg/hr
8640 hrs/year               8640 hrs/year
1,140,480 kwhrs/year        6,842.880 kg/yr steam
Elect. Rate-Php 6.50/kwhr   442,904 li/yr bunker fuel
                            Fuel cost- Php 11.0/li
OPEX- Php 7,413,120/yr      Steam cost- Php 0.71/kg

                            OPEX- Php 4,858,444/yr
      ABSORPTION VS ABSORPTION

ABSORPTION 4.8kg/rt         ABSORPTION 3.8kg/rt

Steam input= 792 kg/hr      Steam input= 640 kg/hr
8640 hrs/year               8640 hrs/year
6,842.880 kg/yr steam       5,529,600 kg/yr steam
442,904 li/yr bunker fuel   357,902 li/yr bunker fuel
Fuel cost- Php 11.0/li      Fuel cost- Php 11.0/li
Steam cost- Php 0.71/kg     Steam cost- Php 0.71/kg

OPEX- Php 4,858,444 /yr     OPEX- Php 3,926,016 /yr
      SAVINGS SUMMARY
1. Bunker fuel = 85,002 li/yr

2. Using 4.8 kg/rt = Php 2,554,676

3. Using 3.8 kg/rt = Php 3,487,107
