sir meron ka po ba charging pressure chart ng bawat refrigerant sa mga ref? chiller o freezer,,ty
@reftechhvacr
@reftechhvacr Год назад
Actually wla naman po charging chart, ang pag check po ng tamang charge ay nakasalalay sa subcooling at superheat..dahil ang pressure nagbabago depende sa surrounding temperature po.

Meron ba kayong video na nag tuturo kung pano bumasa ng pressure gauge ?? Kung sinasabi nyo po kasi na yung nasa loob ng psig is saturated depends on refrigerant . pano po yung psig ? naguguluhan po kasi ako about sa psig dahil nakasulat kadalasan e starts from -30 after vaccum , pano po magiging bilang nun kapag dun nag sisimula ? dahil kadalasan nakasulat e 0 then 1 and so forth . Sana matulungan nyokong intindihin

@reftechhvacr
@reftechhvacr 3 года назад
Hello po sir, kung mapapansin nyo po sa gauge natin sir, may nakasulat jan na ibat ibang refrigerant, at bawat refrigerant ay may nakasulat din na temperature. Sa bawat pressure na mababasa natin sa gauge natin ay may katapat na temperature po. At yang temperature na yan ay ung saturated temperature po natin. Minsan hnd natin napapansing mga nakasulat sa gauge dahil minsan naka focus po tau sa pressure na mga numero.salamat po

Bakit hindi mo kinonsider ang TXV,(thermal expansion valve) then pwede mong gamitin ang subcooling system method of charging.
@reftechhvacr
@reftechhvacr Год назад
Magandang araw po, pasenxa na po at hnd po masyadong maliwanag ang katanungan po ninyo.. ang pag kakaintindi ko po bakit hnd natin e consider ang TXV???? Then gamitin po ang subcooling charging method.? Para sa akin kapag charging ang pinag uusapan , ang pinaka unang tinitignan po jan ay ang evaporation superheat kapag ang pinaguusapan po ay in general system ng different type of system. Kapag flooded evaporator at condenser naman po, ibang usapan din po yan.. Ang hnd ko po ma tumbok bakit subcooling charging method ang gusto nyong basihan sa pag charge po gaya ng sinabe nyo po. Simple way to charge refrigerant into refrigeration system and check a proper charge, use gauge manifold and thermometer. Yan lng po kilangan natin kahit anong method of charging pa po yan.
@tibzmontesa6042
@tibzmontesa6042 Год назад
Hindi ko ibig sabihin ay sa high side pressure ka mag charging, sa low side which is intake ng freon. In the US air conditioning tutorial and lecture, aside from saturated superheat they also take note of subcooling temp, that is why they check first what kind of thermal switch, if they find system is using TXV(thermal expansion valve) they concentrate in the sub cooling. But they never charge freon on the discharged line. They have to follow what the manufacturer suggest on the temp. Say computing the temp from the red scale of freon then minus the outside surrounding temp they can get what temp in farenheit as required by manufacturer. I hope nakuha mo ibig kong sabihin. Superheat is different from subcooling, with respect in taking temp.

Boss pag magkakarga b ng 134a at 404 patayo po b ang tangke o pabaliktad ang tangke sana po masagot nyo para po sa aming baguhan.salamat
@reftechhvacr
@reftechhvacr 2 года назад
Pag 404a po kilangan po liquid po pag nag charged tau. Pag 134a naman po pag malaking system ok lng po na liquid at ok lng din po na vapor. Pero pag posible po na liquid ang pag charged, mas maganda po. Alalahanin po natin na ang iniiwasa po natin sa pag charged ng liquid ay ang may papasok sa compressor natin na liquid lalo na po pag marami ang flow volume ng liquid na pumapasok sa compressor. Maaaring ikakasira po ito ng compressor natin.salamat po

Depende po yan sa temperature setpoint nyo sir. The best way po kunin nyo po ang proper evaporation superheat.. hnd po tau pweding mag base sa suction pressure po para malaman ang tamang charge. Kc ang suction pressure nagbabago din po yan depende sa setpoint at condenser cooling po.. salamat po

4 to 12 po sa superheat depende po sa design ng system. Pero ung pinaka ideal po is 6 to 8. Sa sub cooling naman po 5 to 20 depende parin po sa system. . Pero pagdating po sa malalaking chiller for HVAC po, halos zero superheat po tau jan..depepende paren po sa designed ng manufacturer.. salamat po

@reftechhvacr 3 года назад
Sir yan po ung ideal sir..kahit anong refrigerant. Ibig sabihin pag pasok jan ang superheat at subcooling mo nakakasiguro tau na walang liquid na papasok sa compressor mo at may sapat tayong liquid na pumapasok sa evaporator. At sa subcooling naman nakakasiguro tau na tama ang charge at may sapat taung cooling sa condenser natin at nakakaseguro din tau na liquid na ang refrigerant bago lalabas sa liquid line. Tnx po
