PREFACE

REFRIGERANT IS NOT TO BE BLAMED.

OBJECTIVE: Eliminate the use of CFCs and HCFCs, could also mean using the refrigerant properly to reduce their consumption.

Refrigerant is very expensive and we use it once and throw it away or plan to destroy, something like the consumer society applied to the refrigerants

alternatives to replace the hcfcs
ALTERNATIVES TO REPLACE THE HCFCs
  • Replacement refrigerants (Drop-in with alternative refrigerant): eg. HFC, HC
  • Renewal of existing equipment (Retrofitting)
  • New refrigerants:HFOs and HFCs (R407a, R410a, R422a, R422d, R417A, R32, HFO1234yf ...)Natural (R290, R290/R600, R717, R744)None of these alternatives is included in this presentation

Where possible UNIDO promotes natural refrigerants, while making the transition must take into account the concept of proper management

2 main hcfcs uses in the latinamerica and caribbean
2. MAIN HCFCs USES IN THE LATINAMERICA AND CARIBBEAN

HCFC-22

  • ODP (ODP) = 0.055 (CFC-11 = 1) GWP (GWP) = 1810 (CO2 = 1)Main applications:Air conditioning, chillers (7 to 700kW), commercial refrigeration, condensing units, fisheries, boats in general, transport and others.

HCFC-141b

  • ODP (PAO)= 0.11 (CFC-11=1) GWP (PCG)=725 (CO2=1)
  • Main applications:
    • Blowing agent used for de polyuretane foam.
    • Solvent used for flushing refrigeration systems during service
3 hcfc 22 actual status
3. HCFC-22: ACTUAL STATUS
  • No awareness and good practice.
  • The concept was created and is generally used for R-12
  • Because of its low ODP were not assimilated into National plans
  • It was promoted as an alternative to R-12 without regard to their suitability
  • Vented for repairs and maintenance
  • It is still available at low prices, the market was flooded due to the perverse incentive.
4 hcfc 22 alternatives to reduce consumption
4.HCFC-22: ALTERNATIVES TO REDUCE CONSUMPTION
  • Economic incentive (saving = income)
  • Reuse the refrigerant
  • Recycling: in situ / sent to the existing network
  • Promotion of virgin refrigerant savings through recycling and reuse with their economic advantage
  • Courses focused on proper handling of refrigerant in large consumer savings, commercial refrigeration, large installers, hotels, ships, chiller, etc ...
  • Reclaim interesting concept…
4 hcfc 22 how to reduce consumption
4.HCFC-22: HOW TO REDUCE CONSUMPTION

CONCRETE STEPS (I) - HEAVY-Service site

  • OBJECTIVE: NO VENTING THE REFRIGERANT, NO OPENING THE VALVE
  • Recover all the refrigerant transfer cylinders (liquid transfer pump)
  • Recover the remaining refrigerant (machine recovered)
  • Recycle the refrigerant while doing the service (filter kit)
  • Apply good refrigeration practices (using the adecuate tools)
  • Recharging the refrigerant the shortfall. This not mixture!

RESULT: the refrigerant in good condition can be reused reducing consummption

4 hcfc 22 alternatives to reduce consumption1
4.HCFC-22: ALTERNATIVES TO REDUCE CONSUMPTION

Tools for high volume installations

Liquid transfer pump for refrigerants

Cost ca. US$ 4,500

Set to recycle and separate oil from the refrigerant

Cost ca. US$ 300

Recovery machine for refrigerant

Cost ca. US$ 500

4.HCFC-22: ALTERNATIVES TO REDUCE CONSUMPTION

CONCRETE STEPS (II) – General ServiceAplications

  • Good practices training focused in the need and use of large consumers. Review actual consumption and find how much can be saved changing the concept?
  • Recycling services in place if feasible (cylinders and equipment for recovery and recycling)
  • Take advantage of the R&R network if you can not do directly
  • Reclaim: economically efficient and viable solution, create the infrastructure for reclaim depending on conditions and needs

RESULTS OBTENIED IN DIFFERENT CASES

  • Pilot project was implemented with this concept in Margarita Island in Venezuela, some results:
    • Year 2009 R-22: 100kg recovered and reused; R-134 rd: 475kg recovered, reused 350kg; even with R-404: 49 kg recovered, reused 37kg
    • Application: Recycling in situ using appropriate tools (cylinders and equipment recovery and recycling)
  • Without using the recovery and recycling network in Venezuela in 2010 was recycled about 70 tons of R-22 in different service shops, not big consumers

COSTS & POTENTIAL SAVINGS

A kilo of virgin HCFC-22 costs approx. $ 8  A home air-conditioned has ca. 1 kilo and a type 'split ducted' 3.25kg on average in both cases and can be recycled and reused. Cost of refrigerant = 0 saving 100%  A chiller can have 100kg of R-22 refrigerant value of new $ 800, whether to replace the 20% paid $ 160.  Reclaim the refrigerant has a cost, assuming that the service is paid $ 4 per kilo, the net savings is 50%. (covers transportation costs). If just service is provided.

Reclaimer buys at US$ 2/kg and sells reclaimed at ca. US$ 6/kg, virgin cost US$ 10

5 reclaim alternative to reduce consumption
5. RECLAIM: ALTERNATIVE TO REDUCE CONSUMPTION

RECLAIM a good concept to save refrigerant

Reclaim is the chemical process by which impurities are removedAHRI Certification Air Conditioning, Heating and Refrigeration InstituteAHRI 700 - 2006 revised 2008Establish test procedures for determining the quality of new or reclaimed refrigerants for use in refrigeration and air conditioning whether used or new.

5. RECLAIM: ALTERNATIVE TO REDUCE CONSUMPTION

CERTIFICACION AHRI: All reclaimed refrigerant must undergo tests:

Gas mixing must be incinerated.

1. Acidity: Acid attacks the seals of the systems. Deteriorate inside the storage cylinders. 2. Humidity: Refrigerant high moisture can cause clogging of lines due to the formation of ice affects the heat transfer. 3. Waste high boiling point (oil): High content of non condensable affects the compressibility of the refrigerant, causing high pressures in the system.

5. RECLAIM: ALTERNATIVE TO REDUCE CONSUMPTION

4. Chlorine: Coolant high chlorine level will produce a system with acidic conditions due to the production of HCl. 5. Condensable gases (air): It creates inefficiency in the system. Oil causes formation of additional substances in the system.

6. Purity: mixture of refrigerants not produce the same conditions as pure gas. Gas chromatograph.

7 conclusiones
7. CONCLUSIONES
  • Reducing emissions of ODS
  • The reduced consumption of pure refrigerant is achieved not only with alternatives, if we already have refrigerant saquémosle the most
  • The development of a refrigerant involved investments of millions and we sold after one use that can be recycled
  • Cost savings, environmental seal service
  • With proper use of refrigerant consumption is reduced
  • The service includes recycling is more expensive, but cheaper than that required to add coolant. Good for the installer, user and environment.
  • Win - win.
