F - GAS REGULATIONS

WHAT ARE THEY?EUROPEAN REGULATIONS RELATING TO THE USE OF HCFC REFRIGERANTS

WHY HAVE THEY BEEN INTRODUCED?STUDIES HAVE SHOWN HCFC REFRIGERANTS SUCH AS R22 HAVE A DETRIMENTAL EFFECT ON THEOZONE LAYER & MAY ALSO CONTRIBUTE TO GLOBAL WARMING

IMPACTFROM 1 JANUARY 2010 THE USE OF VIRGIN HCFC’S INCLUDING R22 IS PROHIBITED IN THE MAINTE-NANCE & SERVICING OF REFRIGERATION & AC EQUIPMENT

CONSEQUENCESAVAILABILITY OF EXISTING & RECYCLED R22 GAS WILL DRIVE PRICE UP. NOT A LONG TERM SOLUTION AS THE USE OR RECYCLED HCFC’S INCLUDING R22 WILL BE PROHIBITEDFROM 1 JANUARY 2015

WHAT ARE THE OPTIONS?REPLACE EXISTING PLANT WITH NEW EQUIPMENT UTILIZING APPROVED HFC GASES.

PROS. NEW EQUIPMENT LIKELY TO BE MORE EFFICIENT, REQUIRE LESS MANTENANCE & THE REFRIGERANTMEETS THE REQUIRED REGULATIONS

CONS. COST, DISRUPTION TO OPERATIONS , THE CAREFUL , SAFE REMOVAL & DISPOSAL OF R22SUBSTITUTE R22 WITH APPROVED HFC ALTERNATIVE

PROS EXTENDS THE LIFE OF EXISTING PLANT WHERE EQUIPMENT IS IN GOOD CONDITION & IS PERFORMINGAS DESIGNEDREDUCED COST & DISRUPTION WHILST MEETING THE REQUIRMENTS OF THE REGULATIONS

CONS?


F - GAS REGULATIONS

THE REGULATIONS ALSO IMPOSE OBLIGATION ON OPERATORS OF REFRIGERATION PLANTS USINGHFC’S INCLUDING:

• PREVENTION OF LEAKS OF HFC REFRIGERANTS & THE REPAIR OF ANY LEAKS ASAP• REGULAR LEAK TESTING 3, 6 OR 12 MONTH DEPENDING ON SIZE OF PLANT• MAINTAIN SYSTEM RECORDS• FITTING OF AUTOMATIC LEAK DETECTION SYSTEMS ON LARGER SYSTEMS• ONLY CARRY OUT GAS RECOVERY USING CERTIFIED PERSONNEL• CORRECTLY LABEL NEW PLANT, HFC TYPE & QUANTITY, ETC

ALTERNATIVE REFRIGERANT GASES

THERE ARE A NUMBER OF DIFFERENT GASES AVAILABLE & USERS SHOULD INVESTIGATE THOROUGHLYBEFORE COMMITING THEMSELVES TO A PARTICULAR GAS, MISTAKES TEND TO BE EXPENSIVE

DESPITE SOME CLAIMS, THERE IS NO SINGLE GAS THAT CAN REPLACE R22 IN ALL APPLICATIONS

THE RS SERIES OF REFRIGERANTS FROM STAR INTERNATIONAL

• DEVELOPED & MANUFACTURED IN THE UK• WORLDWIDE SUPPORT• A1 SAFETY CLASSIFICATION FROM ASHRAE

KEY BENEFITS OF USING RS SERIES OF REFRIGERANTS

• FACILITATES REPLACING OZONE DEPLETING SUBSTANCES• COMPATIBLE WITH MO/AB• LOW COST RETROFIT• AVOIDS USING EXPENSIVE & HYGROSCOPIC POE OILS• SIMILAR PERFORMANCE TO PRODUCTS BEING REPLACED IE R12, R22 & R502• ZERO OZONE DEPLETION POTENTIAL

OIL COMPATIBILTY

• MINERAL OIL (MO)• ALKYLBENZENE OIL (AB)• POLYOLESTER OIL (POE)• POLYALKYLENE GLYCOL OIL (PAG)

RS-24, RS-44, RS-45, RS-52 & RS-25 ARE COMPATIBLE WITH ALL OF THESEREFRIGERATION OILS

RS-44

• R22 REPLACEMENT PRIMARILY FOR A/C• SUITABLE IN SYSTEMS WITH FIXED ORIFICES & EXPANSIONS DEVICES• LOWER DISCHARGE PRESSURES• LOWER DISCHARGE TEMPERATURES• HIGHER CAPACITY THAN R417A

RS-45 (R434A)

• SAME CAPACITY AS R22• REPLACES R22 ACROSS TEMP RANGE• 1.5 DEG GLIDE• POTENTIAL USE IN FLOODED SYSTEMS• LOWER DISCHARGE TEMPERATURE• UNSUITABLE FOR RETROFIT IN FIXED ORIFICE SYSTEMS • OEM PRODUCT• NOTHING COMPARABLE:

1) Capacity to match R22(2) Use with MO/AB/POE(3) Pressures similar to R22

WHY USE RS-45?

• COMPATIBLE WITH TRADITIONAL LUBRICANTS (AB & MO)• SAME CAPACITY AS R22 AT HIGH & LOW TEMPERATURES• AVOIDS COSTLY RE-TOOLING TO HIGH PRESSURE R410A• NOTHING SIMILAR FOR S&T EVAPS• SIMILAR PRESSURES TO R22• SIMILAR COEFFICIENT OF PERFORMANCE TO R22• CONSIDERABLY LOWER DISCHARGE TEMPERATURE THAN R22• NEAR AZEOTROPIC - LOW TEMPERATURE GLIDE 1.50C• SAME COMPRESSION RATIO AS R22• AVOIDS PROBLEMS OF FRACTIONATION• A SINGLE REFRIGERANT REPLACEMENT FOR R22 ACROSS

THE RANGE OF APPLICATIONS WHERE R22 IS COMMONLY FOUND

RS-44 & RS-45 APPLICATIONS

• RS-44 IS SUITABLE FOR USE BOTH IN FIXED ORIFICE & SYSTEMS WITH AN EXPANSION VALVE.• RS-44 WORKS WELL AS A REPLACEMENT FOR R22 AT MEDIUM & HIGH TEMPERATURES.• RS-44 IS PARTICULARLY EFFECTIVE IN UNITARY AIR CONDITIONING SYSTEMS• REPLACING R22 IN AN EXISTING SYSTEM WITH A CAPILLARY TUBE OR FIXED ORIFICE, RS-44 IS THE

PREFERRED PRODUCT• RS-44'S LOWER DISCHARGE PRESSURE PROVIDES CONSIDERABLE OPERATING BENEFITS• RS-45 IS A CAPACITY MATCH FOR R22 ACROSS THE TEMPERATURE RANGE

RS-44 & RS-45 APPLICATIONS

• RS-45 HAS BEEN FORMULATED FOR USE BY ORIGINAL EQUIPMENT MANUFACTURERS• AT LOWER TEMPERATURES, BELOW -25OC EVAP, RS-45 IS ESPECIALLY EFFECTIVE AS AN

R22 REPLACEMENT• RS-45 WITH ITS LOW GLIDE (AT 1.5oC CONSIDERABLY LOWER THAN R407C) PROVIDES A

SIGNIFICANT BENEFIT IN SPECIFIC APPLICATIONS, EG FLOODED SYSTEMS.• BOTH RS-44 & RS-45 HAVE CONSIDERABLY LOWER DISCHARGE TEMPERATURES THAN R22
