Code of partial brand breakdownIn eavesSu Jing air canAir of green jade Lai canUnripe can circulate code of trouble of engine of hot water of hot pump of type air source:
Protect functional description1, high-pressured protection
In system of aircrew fluorine route, install in high-pressured side high-powered high grade high pressure is pressed accuse switch, understand pressure 2.4 ~ 3.15MPa, when the rated numerical value that exceeds high-pressured pressing to accuse when systematic pressure, high-pressured pressing accuses to disconnect, aircrew protection stops machine, when pressure regains normal level, high-pressured pressing accuses automatic restoration, aircrew opens mechanic automatically to make.
2, low-pressure protection
In system of aircrew fluorine route, install in low-pressure side high-powered high grade low pressure is pressed accuse switch, understand pressure 0.05 ~ 0.15MPa, when aircrew existence leaks fluorine, evaporate pressure passes low, system existence is dirty when waiting for breakdown, systematic pressure approachs the rated numerical value that control under low pressure, low pressure pressing accuses to disconnect, aircrew protection stops machine, when pressure regains normal level, low pressure pressing accuses automatic restoration, aircrew opens mechanic automatically to make.
3, compressor sheds overload protection too
Aircrew compressor chooses the cereal annulus compressor of world famous brand, the orgnaization is protected of overload in compressor interior, the connection that make the same score key is used between the hub of compressor and main shaft; Smooth key basic level uses metallic data, outer plating has the metalloid stuff that has certain hardness and flexibility. Use practical and new-style technology program, make compressor overload protected an orgnaization to satisfy a structure simple, treatment convenient, ship-fitter art simple, cost is low and when be started in compressor and be being shut, overload protection orgnaization has amortize effect, reduce the demand of noise.
4, flow protection
Aircrew advocate board set current to protect a function, switch on the mobile phone when aircrew electrify, pressure of the current that drink water already reached the numerical value of the design, namely current switch already closed, aircrew open.
5, the delay time that start
Aircrew is in electrify open after 30 seconds, open of circular water pump works circularly, after circular loop water pump moves 2 minutes, fan (change frost to run except) move with compressor synchronism, avoided to start electric current to be mixed greatly too the problem that the anhydrous in condenser makes aircrew doing is burned.
6, exhaust temperature protection
Aircrew is in first electrify detects disconnect to call the police instantly and show trouble, restore succeed add to move; When moving normally, exhaust temperature exceeds exhaust to protect set temperature to be worth namely 95 ℃ are in 3 times / inside the hour when, delay time of the compressor after restoring 3 minutes of restart, the system restores to move, more than 3 / hour, the system stops instantly machine, call the police at the same time and show trouble. (Note: ? ; Inside hour of? of of ぴ a surname when, after showing protection of breakdown code; restores at the same time when occurrence protection, breakdown code delay time restores not to show after 5 minutes, in inquiry condition issues) .
7, appearance sequence is gone against photograph or lack photograph protection
After aircrew electrify, detect inside 30 seconds sequence of power source appearance, go against when appearance sequence photograph or be short of, control plate cuts off all output power source, call the police at the same time and show trouble.
8, sensor breakdown protection
At the same time attaint closes annulus lukewarm sensor, valve lukewarm sensor machine;
Be in charge of lukewarm sensor to have one bad, will be with good sensor value accurate;
Annulus lukewarm sensor is bad, change frost according to providing gentle run time;
Tubal lukewarm sensor is bad, when annulus lukewarm sensor ≤ when 6 ℃ , time change frost;
Exhaust temperature has one bad, will be with good sensor value accurate, two sensor is bad at the same time, cancel to discharge protection;
Into water temperature and cistern temperature 1 sensor has one bad, will be with good sensor value accurate; If two open circuit at the same time, close machine. (prevent frostbite runs except)
Cistern temperature 2 sensor are bad, cancel its relevant movement;
Backwater temperature sensor is bad, abolish control of backwater of difference in temperature; Mix except cistern temperature sensor the sensor that drink water damages at the same time or Wen Chuangan of annulus lukewarm sensor, canal implement outside when damaging at the same time, call the police and displaying breakdown code, do not call the police not to display breakdown code when the others sensor is bad, enter look up of look up condition only.
9, winter prevent frostbite moves
Aspic of ﹑ water pump is in charge of to crack to avoid water when winter bides his time, when aircrew satisfies the following requirement, enter prevent frostbite automatically to move.
Should enter 1 ℃ of water temperature ≤ and machine down time exceeds 60 minutes, water pump of the loop that start 5 minutes, if take water temperature still 4 ℃ of ≤ , start compressor and fan, till ≥ of the temperature that drink water 10 ℃ or job are exited 10 minutes.
Note: If receive damage of water temperature sensor, should satisfy environmental temperature ≤ only 0 ℃ , stop machine hind, every pass 60 minutes, water pump of the loop that start 5 minutes.
10, protection of leakage of electricity
Aircrew interior protects switch of leakage of electricity, when aircrew runs existence leakage of electricity, aircrew protection closes machine.
11, ground connection protection
Strict according to GB4706.1-98 in of electric demand " I kind implemental its electrical shock defends rely on basic insulation not only and the appliance that includes an add and safe preventive measure. Its preventive measure is with in case basic insulation invalidation, easy the method with touched electric won't electrified component is will easy touched electric component join secures the ground connection in wiring to protect conductor to establishment " , rise to protect action of ground connection lead.
