REPORT ON HYDROCARBON REFRIGERANTS (HCs) TRAINING WORKSHOP FOR MEDICAL ENGINEERING TECHNICIANS (METS)

Venue: NATIONAL VACCINE CENTRE - MINISTRY OF HEALTH (MOH), KITENGELA Date:13TH – 18TH MARCH 2016 and 21ST – 24TH MARCH 2016

PREAMBLE

The three Days Workshop was conducted at the National Vaccine Centre in Kitengela under the

Ministry of Health, Kajiado County, from Monday the 13 th to Friday the 18th March 2016 and from

Monday 21st to Thursday 24th March 2016. The Workshop was funded by the Multilateral Funding

Agency, The German International Collaboration (GIZ, Proklima) Nairobi Office, in co-ordination

and collaboration with the National Ozone Unit (NOU), Nairobi, of the Ministry of Environment,


Natural Resources & Regional Authorities and the National Vaccine Centre of the Ministry of Health

(MOH) under National Vaccination and Immunization Program

The course was facilitated mainly by Mr Edward Kamau of Nairobi Technical Training Institute and

Mr. Joseph Rugut of Christian Health Association of Kenya (CHAK)

INTRODUCTION

Hydrocarbon refrigerants, though having been used in the early years, are now seen as a viable and

low cost alternative for domestic and small commercial refrigeration appliances in the phasing out of

Hydro Chlorofluorocarbons (HCFCs) refrigerants. Hydrocarbons (HCs) refrigerants are the most

environmentally friendly commercial technology option available today. Blends of hydrocarbon

refrigerants can be used as drop-in solutions for R 22 and R134a refrigeration systems, but the

present working practices in production and servicing the new systems will have to be improved

under safety aspects only.

Precaution with respect to the flammability of the hydrocarbon refrigerant during servicing

procedures has to be considered very carefully.

PURPOSE

There is need to observe the Montreal Protocol in terms of protecting the Ozone layer, by reducing

and controlling the use of the Ozone Depleting Substances (ODS), that have adverse effects on the

Ozone due to their high Ozone Depleting Potentiality (ODP) and Global Warming Potentiality

(GWP), which leads to high global temperatures. In so doing, we may revert towards a Greener

World, by helping the Ozone layer reconstitute itself with time, if only we used compounds that do

not exhibit these characteristics.

The Workshop intended to bring awareness, acceptance and adoption of safe use and good practices,

with the latest and safest Hydrocarbons (HCs) refrigerants and equipment to the Refrigeration and

Air Conditioning Trainees so that they can disseminate the same new Technologies to others by

organizing in house training in their respective workshops and places they are employed.

Extensive Theoretical and Practical sessions were intended to build confidence to the Trainees so

that they could embrace the New Technologies on HCs Refrigerants while using related Tools and

equipment.

Concern on HCs Refrigerants flammability were highlighted and addressed comprehensively

regarding how to handle, store and carry out conversions of systems from Ozone Depleting

Substances refrigerants to Non depleting substances and those affecting the climate change (GWP

substances)

Class in session

ACTIVITIES

In order to impart these new knowledge and skills the workshop was organised to include sessions of

Theoretical, with frequent class demonstrations, and Practical hands-on in a workshop situation, In a

three days schedule for each group (APPENDIX 1), in line with previous trainings that have taken

place in the country, training some of the Technicians in the company.

The workshop practical in MET were held at the workshop while the conference was held at the

Conference Hall. Meals were served at the Main Restaurant of the conference centre.

The Training was officially opened by the Dr. Maree of the National Vaccine and Immunization

Program (Kenya). Other officials present included Dr. Mutie, Dr. Charo, Engineers in the Centre and

the GIZ Administrator Madam Josephine Mutero.

The key areas of training were on the following

The Montreal Protocol and Ozone depletion

Refrigerants preview and Refrigerant Phase out schedule (HPMP)

Alternative refrigerants

Hydrocarbons (HCs) refrigerants and their properties

Safe handling and storage of HCs

Tubing connections by brazing and use of non-flame methods – Lokring Technology

CFC, HCFC and HCF conversions to HCs (R290 & R600a)

Good repair Practices.

Class room demonstration of Refrigeration Technologies and Tools

Workshop practices on Brazing, Lokring Technology

Recovery, Evacuation and Charging.

Practical conversion of R134a into R600a and R290

Area on Vaccine coaching (handled by MET Engineers)

Practical sessions in the workshop

CONCLUSION REMARK

4


The workshop was a great success in that the trainees were keen and focused in their objectives

which were positively achieved.

As a way of improving the programme and in order to make the Montreal Protocol a reality the

trainees made recommendations which were envisaged to have realistic objectives.

There is need for more training on HCs and new technologies in Refrigeration and Air

Conditioning,

More time is required for the Training especially on Practical

More training on the conversion of cold storages and Air Conditioners

Request for refrigeration tools specifically Lokring system and recovery machines from GIZ Proklima at reduced prices to all the Counties in the Country

RECOMMENDATIONS

1. The training be conducted to other Technicians in the Counties as only one person

was selected to attend the training

2. GIZ to sponsor Technicians for training abroad.

3. More Equipment be availed for training centres like MET and in County Hospitals
