R290 yog ib hom tub yees uas tseem hu ua propane. Nws yog hydrocarbon refrigerant uas muaj lub ntiaj teb ua kom sov tsis muaj peev xwm (GWP) thiab ozone depletion peev (ODP). R290 feem ntau yog siv rau hauv tub yees thiab cua txias, nrog rau kev siv tub yees hauv tsev thiab kev lag luam. Nws yog ib lub tub yees ua tau zoo heev uas muab kev ua haujlwm txias txias nrog kev siv hluav taws xob tsawg. Txawm li cas los xij, vim nws qhov flammability, nws yuav tsum tau tuav tshwj xeeb thiab kev tiv thaiv kev nyab xeeb thaum lub sij hawm installation thiab txij nkawm.
R290, tseem hu ua propane, yog cov roj tub yees nrog cov kev ntsuas hauv qab no:
Cov tshuaj formula: C3H8
Molecular Luj: 44.10 g / mol
- Boiling point ntawm atmospheric siab: -42.1 degree (-43.8 degree F)
- Qhov ntsuas kub tseem ceeb: 96.7 degree (206.1 degree F)
- Lub siab tseem ceeb: 42.5 bar (616.9 psi)
- Ozone depletion peev xwm (ODP): 0
- Ntiaj teb no warming muaj peev xwm (GWP): 3 (tshaj li 100-xyoo lub caij ntuj sov)
R290 yog cais raws li A3 tub yees, txhais tau tias nws yog cov nplaim taws heev thiab yuav tsum muaj kev nyab xeeb tshwj xeeb thiab tuav cov txheej txheem. Nws feem ntau yog siv rau hauv cov tub yees me me thiab kev siv cua txias, nrog rau hauv kev thauj mus los tub yees.
