- Kanggo 1 * utawa 2 *
MWP ora bakal kurang saka meksa diterangake ing bagean 9.2 saka ANSI / ASHRAE 15 kanggo refrigerant digunakake ing sistem. Sawise ngisi daya, sistem kasebut kudu ditandhani karo refrigeran lan lenga sing digunakake.
"DCRE mung bisa digunakake kanggo A2L nalika inti padhet diselehake. DCRE ora diidini digunakake minangka panrima.
Brazing
Welding
Praktik paling apik pelanggan isih dibutuhake:
- Gunakake bungkus udan nalika nginstal.
- Braze sendi.
- Ayo padha kelangan.
- Resik area brazing / welding sawise instalasi (mbusak flux isih karo sikat).
- Iki minangka operasi sing penting lan kudu ditindakake kanthi ati-ati kanggo mbusak kabeh fluks sing isih ana.
- Paint / Anti-korosif perlu kanggo nutupi kabeh bagean baja kapapar, wilayah ngendi Paint ireng asli wis burned adoh amarga brazing lan ing paling 3 cm watara tembaga.
- Paint joints kaping pindho.
Carane ngencengi bolts
Gasket
Aja nginstal gasket sadurunge soldering.
Cathetan: Konfirmasi paking tutup ndhuwur sing bener dipilih. Ana 2 gasket:
- DCR lan DCR / H
- DCRE
Rekomendasi
- Gunakake lenga cilik menyang gasket sadurunge dipasang.
- Luwih becik lenga sintetik POE utawa PVE, sanajan lenga tujuan umum bisa digunakake.
Cathetan: Aja nggunakake maneh gasket.
Sekring lan/utawa Plug opsional, torsi pengencang sing disaranake:
- Sekring: 1/4”NPT – 3/8” Flare: 20 Nm / 14.75 ft-lb nglamar 2 kanggo 3 mbungkus tape Teflon.
- Plug: 1/4” NPT: 50 Nm / 36.87 ft-lb nglamar 2 kanggo 3 mbungkus tape Teflon.
Referensi
Nilai torsi sing kasebut mung ditrapake kanggo baut sing diwenehake dening Danfoss.
Saben langkah kudu ditrapake sawise urutan gambar.
FAQ
P: Apa DCRE bisa digunakake minangka panrima?
A: Ora, DCRE ora bisa digunakake minangka panrima. Iku mung cocok kanggo A2L nalika inti ngalangi diselehake.
P: Apa jinis lenga sing kudu ditrapake ing gasket?
A: Luwih sintetik POE utawa lenga PVE dianjurake kanggo nglamar kanggo gasket sadurunge perakitan. Nanging, lenga tujuan umum bisa digunakake.
