1.2 Features and advantages
Advantages
This unit is using the latest DC inverter technology. It can adjust its
working frequency, so to give out its output according to the loading. It can
work down to -25 with good COP.
The unit is designed with easy installation that no refrigerant charging
or copper pipe brazing is required on site. It can be widely used in house
and villa.
This unit is with environment-friendly refrigerant R410A, which also
provides one of the highest energy efficiency ratings in the industry.
Output of the compressor and therefore the energy input requirements are
constantly monitored and adjusted at the most optimum level for the given
indoor and outdoor environmental conditions and the user's desired
demands from the system.
Microprocessor control system contains several enhanced software
features to make the operation of the system most advantageous and
pleasing, under varying environmental conditions.
Special vibration absorbers on the compressor allow operation of the
system with ultra low noise.
Microprocessor is programmed to allow operation under wide range of
input voltages from 160V-260V and soft starting with lower current draw at
each compressor start-up.
Auto-restart function keeps all settings in memory and automatically
resumes the operation after a power failure.
Compressor crankcase heater and bottom plate heater are available
as options for extreme cold conditions, enabling the unit to work in
very low ambient temperatures with much lessened defrost
frequencies. Both these optional heaters are electronically controlled
based on the outdoor ambient temperatures and a sophisticated logic.
Programmable timer function provides unattended operation of the
system.
Acrylic coated enhanced aluminum fins on the coil heat exchanger
extends the fin life against corrosion and allows easier rainwater
wash-down as well as faster defrosts.

1.8 Põhifunktsioonid
Mälu funktsioon
Seade taastab viimased seaded automaatselt pärast
elektrikatkestust. Kompressori taaskäivituse viide on 3 min et kaitsta
kompressorit.
Kompressori eelsoendus
Kui kompressor on pingestatud esmakordselt ja kompressor ei
tööta, juhul kui välisõhu temp on alla -5℃, käivitub kompressori
eelsoendus . Pärast seda kui kompressor on töötanud, 3 tundi ja peatub,
juhul kui välistemperatuur on alla -3℃, siis käivitub kompressori eelsoendus
.
Kui kompressori karterisoendus töötab ning välisõhu temperatuur tõuseb üle 0℃,
või seade vajab kompressori käivitamist , kompressori eelsoendus lõpetatakse .
Välise küttekeha juhtimise võimalus
Kui seade töötab küttereziimil ja välistemperatuur
on 1 kraad alla 0℃, ning kompressor on töötanud 25 minutit,
kontroller kontrollib süsteemi iga 15 minuti järel. Väline
elektriline küttekeha lülitub sisse kui alljärgnevad tingimused on täidetud:
A. Kompressor töötab kõige suuremal kiirusel;
B. Seadetemperatuur on 3 kõrgem kui veetemperatuur.
C. Veetemperatuur tõuseb vähem kui 1 15 minuti jooksul.
Kui veetemperatuur saavutab etteantud väärtuse ja , säilitab väärtuse
stabiilsena vähemalt 1minuti või kompressor seiskub, siis väline küttekeha
lülitub välja, sest süsteem teostab uuesti tingimuste täidetuse kontrolli (A,B,C).
Seadmest väljuva vee temperatuuripiirang (Kasutatakse ainult juhul
kui seadet juhib toatemperatuuriandur )
Kui (väljuva vee temperatuur) VVT 34 ℃, siis kontroller piirab
kompressori töökiirust ', jättes hetkel oleva kiiruse maksimumkiiruseks.
.
Kui VVT36 ℃, kompressori töökiirust vähendatakse
kõige väiksema kiiruseni, kuni veetemperatuur langeb alla
34 ℃. Siis kontroller peatab kompressori kiiruse vähendamise
16
1.8 Põhifunktsioonid
ja hakkab seda uuesti tõstma,kuid siis on maksimaalne kiirus üks tase madalam kui
kiirus enne seda kiiruse vähendamise protsessi oli .
Kui VVT32 ja kompressor töötab pidevalt 60 minutit
ilma sagedust vähendamata või süsteemi seiskumata kaitselülituse tõttu, siis
kompressori'pöörlemiskiiruse piirang jõustub.
Kui VVT38või kompressori pöörlemiskiirus on alandatud kuni
madalaima kiiruseni kuid vee väljundtemperatuur on ikkagi kõrgem kui 34siis 2
minuti pärast kompressor seiskub. Pärast kui vee väljundtemperatuur langeb
alla 32 ℃, kompressor taaskäivitub.
Sulatusfunktsioon kütmisel
Alljärgnev kirjeldab sulatustoimingut kütmisel (heating mode)
a) Sulatus algab alljärgnevate tingimuste saabumisel,
(sulatuse märk tablool vilgub);
1) Aurusti korpuse temperatuur on alla -3ja kestab vähemalt 3 minutit.
2) Kompressor on töötanud vähemalt 5 minutit
3) Kompressori tööaeg kokku on pikem kui intervall kahe
sulatuse vahel
b) Süsteem lõpetab sulatuse kui üks alljärgnevatest tingimustest on saabunud
1) Sulatus kestab üle 8 minuti
2) Sulatus on kestnud kauem kui 10 sekundit ja aurusti korpuse
temperatuur on kõrgem kui 17℃.
Kondensaatori ülekuumenemise kaitse
Kui kondensaatori temperatuur on52℃, seadmel rakendub kondensaatori
ülekuumenemise kaitse, ja kompressor alandab pöörlemis-
kiirust kuni F1, kuni see temperatuur langeb madalamaks kui 49℃.
Siis kompressor vähendab kiirust 1 taseme madalamaks kui varem oli
ülekuumenemise kaitse rakendumisele eelnev pöörlemiskiirus.
17
1.8 Põhifunktsioonid
Kui see Temp langeb alla 47ja see kestab üle 5 minuti, siis piirang
kompressori pöörlemiskiirusele lõpetatakse .
Kui kondensaatori temperatuur tõuseb üle 55ja kestab üle 5 sekundi,
siis kompressor seiskub. Piirang lõpetatakse kui
see temperatuur langeb alla 47℃.
Kompressori taaskäivitumise kaitse
During compressor's start-up or running, if the controller detects no
feedback from compressor, or abnormal loads inside compressor, or
improper start-up, compressor will stops for 3 minutes and then re-start.
(Compressor can re-start at most three times when fed with power; if this
problem still exists, the controller will judge it as compressor driving-
failure, and relevant protection will be triggered. Then compressor can
only be turned on after problem solved and system re-fed with power.
Kompressori ülevoolukaitse
Kui seadme töövool on teatud väärtust ületav, siis kontroller
hakkab piirama vastavalt kompressori töösagedust, kuni
töösagedus enam ei suurene.
Kui see vool on 0.5A väiksem etteantud piirväärtusestkompressori
töökiirust vähendatakse 1Hz/sekundis kuni sageduseni 30Hz,kuni töövool
on väiksem kui 16A.
Kui töövool on sellest 1A suurem siis kontroller
peatab kompressori, olenemata sellest millisel kiirusel kompressor töötab.
Kompressori kuumagaasi temperatuuri kaitse
Kui kompressori kuumagaasi temperatuur ületab 92℃, siis
kontroller piirab kompressori töökiirust pöördesageduse vähendamisega .
Kui temperatuur ikkagi tõuseb üle 97 ℃, siis kontroller salvestab töösageduse ja alandab pöördeid it kuni 30Hz. Kui kompressori
kuumagaasi temperatuur langeb alla 87℃, siis see protsess lõpeb ja
kontroller häälestab kompressori pöördesageduse vastavalt
küttevee temperatuuri ja etteantud temperatuuri vahele; Kui kompressori
18
1.8 Põhifunktsioonid
maksimaalne pöördesagedus on 1 tase madalam kui salvestatud väärtus.
Kui kompressori kuumagaasi temp. on alla 92ja kestab üle
10 minuti, Siis maksimaalne pöördesagedus suureneb 1 taseme võrra.
Kui see kuumagaasi temperatuur ületab 103℃, kompressor seiskub,
ja välisosa ventilaatori mootor lülitub välja 15 sekundi pärast.. Seade käivitub
kui kuumagaasi temperatuur langeb alla 90 ja
kompressor on seisnud 3 minutit.
Viide kompressori käivitamisel
Pärast kompressori seiskamist, saab kompressor käivituda uuesti 3 minuti pärast.
See toimib jahutusel või kui seade vahetab töö viisi
jahutuse ja kütte vahel. Kui seade on
pingestatud esmakordselt siis kompressor käivitub 1 minutiga
peale ühendust siseosa ja välisosa vahel .
Kaitselülitus alapinge vastu
Kui elektrivõrgu toitepinge on alla 190V ja see kestab üle
30 sekundi, piiratakse kompressori pöördekiirust.
Kui toitepinge on kõrgem kui 195V, piirang
tühistatakse.
Kui pinge langeb alla 158V, siis seade seiskub ja
kontrolleri ekraanil on näha veakood.
Kui pinge tõuseb uuesti 162 voldini, siis seadme toimingud taastuvad.
