6, when using, available automatic mode is controlled:
The temperature of automatic mode is differentiated the temperature T that depends on indoor return air inlet 16 places
Return airWith design temperature T
IfIn indoor temperature data of passing back by sensor RT5 and setting data contrast judge determine to enter which kind of operational mode.For example, design temperature T
IfBe 24 ℃, deviator is 2 ℃.Panel by line control machine OP is presented on the display screen, then the temperature criterion such as the following table of this automatic mode
| Temperature range | Judgment model |
| ?T Return air≤22℃ | Heat |
| ?22℃＜T Return air＜26℃ | Dehumidifying |
| ?T Return air≥26℃ | Refrigeration |
After automatic mode is determined, will carry out refrigeration, dehumidify or heat work according to the pattern of determining.In addition, determine the open and close condition of air-valve plate 15: for example by 12 ℃ of open and close conditions of setting air-valve plate 15:
1. air-valve plate 15 is opened.When outdoor temperature (temperature that RT3 records at fresh wind port 11) is less than or equal to 12 ℃, T simultaneously
Return air〉=T
IfDuring+deviator, then KA2 gets electric adhesive, and air-valve plate 15 is opened in air-valve actuator FA action, is cooled off in fresh wind port 11 inlet chambers by outdoor cold air; Compressor CM1 quit work and entered power save mode this moment;
2. air-valve plate 15 is closed.When outdoor temperature (temperature that RT3 records at fresh wind port 11) greater than 12 ℃; Or T
Return air≤ T
IfIn the time of-2 ℃, KA2 dead electricity then, air-valve plate 15 is closed, and air is only in indoor circulation.
6.1 refrigeration
The cryogenic temperature control procedure:
Indoor master control borad compares according to the temperature and the design temperature of the sensor RT5 detection at return air inlet 16 places, comes the start-stop of instruction control unit control compressor CM1.At temperature setting range T
IfBe 24 ℃, when deviator is 2 ℃ (being that the temperature setting range is 22-26 ℃), carry out work:
Temperature T when return air inlet 16 places (by the RT5 sensing)
Return air(for example being 27 ℃) 〉=T
IfDuring+deviator, the compressor CM1 start refrigeration (KM1 get electric adhesive) corresponding with indoor fan EM, outdoor fan FM1 starts simultaneously.At this moment, when being 28 ℃ (greater than 12 ℃) as outdoor temperature, then air-valve plate 15 is closed, and air is only in indoor circulation, by above-mentioned standard cooling condition operation (outdoor fan FM1 moves simultaneously); When being 10 ℃ (less than 12 ℃) as outdoor temperature, then air-valve plate 15 is opened, air in the chamber, interior outer circulation, compressor CM1 shuts down (KM1 dead electricity) (outdoor fan is shut down equally with energy efficient) with energy-conservation.
6.2, the dehumidifying.Work as T
If-2 ℃≤T
Return air(for example 23 ℃)≤T
IfIn the time of+2 ℃, be dehumidifying, this moment, KM1 got electric adhesive, compressor CM1 operation 6 minutes; KM1 dead electricity then, compressor CM1 stopped 4 minutes, so circular gap operation; And KM2 gets electric adhesive, and the interval dehumidifying is carried out in indoor fan EM operation.
Under air vent mode, KM2 gets electric adhesive, has only indoor fan EM work.
6.3, heat.If return air inlet 16 place's temperature drop to T
Return air(when for example being 21 ℃)＜T
IfDuring-deviator, compressor CM1 shuts down (KM1 dead electricity).Heat: this moment, KM3 got electric adhesive, and electric heater RH starts; KM2 gets electric adhesive, and indoor fan EM operation when outdoor temperature is low excessively, causes indoor temperature T
Return airReduce, when for example reducing to below 21 ℃, then air-valve plate 15 is closed, and the air of heating is only in indoor circulation.
6.4, other.
1, electrical heating operation rule
1.1 electrical heating operation input condition.
1) as indoor temperature T＜T
Set-deviate (4 ℃),
2) indoor fan is opened more than the 30S.
1.2 electrical heating condition out of service.
1) pattern conversion, fault or shutdown,
2) T
Return air〉=T
Set+ 1 ℃,
3) the electrical heating overtemperature prote disconnects.
2, record delivery temperature T as exhaust gas temperature sensor RT 1
ExhaustIn the time of＞135 ℃, then determine the excessive discharge temperature warning.
3. outer tube temperature sensor RT 2 records the outer tube temperature T
Outer tubeIn the time of＜-5 ℃, satisfy conditions such as time simultaneously, then defrost
Process.
7, the power supply of blower fan EM automaticallyes switch
When unit during by normal operating conditions, the power supply that causes because of reasons such as outages interrupts suddenly, and the fan power automatic switching control equipment can automatically switch to standby.Make the indoor ventilation state that is in, be unlikely in the too fast rising of machine room indoor temperature.When the power bus dead electricity, the KA1 dead electricity, the normally-closed contact closure of KA1, the stand-by power supply commutation circuit of indoor fan EM enters duty, delayer KT time-delay is after 3 minutes, the normally opened contact closure of delayer KT, KA3 gets electric, and the KA3 normally-closed contact disconnects (will disconnect from the EM normal power supply circuit that end points OP1 draws), make the KM2 dead electricity, the normally-closed contact closure of KM2, KA3 normally opened contact closure makes KM4 get electric adhesive simultaneously, the normally opened contact closure of KM4 then, make inverter LPD work, again indoor fan EM is started, this moment, indoor fan EM was powered by the stand-by power supply of 48VDC battery.
