Mech. Engineering-HVAC Oil Separators

THE CPWD, PWD, MES AND OTHER GOVERNMENT DEPARTMENTS FOLLOWS ANTIQUE SPECIFICATIONS FOR HVAC AND REFRIGERATION BY BRITISH WITHOUT ANY UPDATING OF THE ENGINEERING DEVELOPMENTS IN THE FIELDS. EVEN THE PROQIREMENT OFFICERS AND THE ENGINEERS ARE NOT UPDATE OF THE DEVELOPMENTS AND INSTALLATIONS. IN AN MORTUARY COOLER OF 9 TR AT 4 DE C INSIDE CONDITIONS WITH KIRLOSKAR FK 4 OPEN COMPRESSOR WITH R 22 WAS USED WITH OIL SEPARATOR AT DISCHARGE LINE WITH FLOAT VALVE TO DRAIN THE OIL INTO CRANK CASE. AS PER FUNDAMENTALS OF REFRIGERATION, FOR APPLICATION OF THIS OPERATING TEMPERATURE AS THE OIL WILL AUTOMATICALLY EVAPORATE AND RETURN BACK TO CRANK CASE FROM THE EVAPORATOR AT THE RATE IT LEAVES THE COMPRESSOR. THE INSTALLATION WAS DONE BY A REFUGEE COMPANY, TAKEN THEIR 90% AND WASHED THEIR HANDS OFF. COMPRESSOR BREAK DOWNS VERY FREQUNDILY. I HAD VERY HARD TIME TO AGREE THE END USER TO DISMANTLE THE OIL SEPARATOR AND THE INSTALLATION WILL BE WORKING WITHOUT ANY PROBLEM. I PRODUCED VOLUMES OF MATERIALS FROM NET INCLUDING ICI INDS. AND CARRIED OUT THE MODIFICATIONS. THE COOLER WORKING SATISFACTORILY WITHOUT ANY MAINTENANCE AND THE PWD ENGINEER WHO ALLOWED THE CHANGE AND PUT BACK IN OPERATION THE COOLER WHICH WAS OUT OF ORDER FOR OVER YEARS BLOCKING THE MONEY GOT PROMOTION WITH RAISE IN PAY ETC AND I STAND NO WHERE.
