After the startup of compressor 2, the refrigerant in air-conditioning system begins to circulation, now opens refrigerant heater 13 and carries out Preheating can do sth. in advance to heat refrigerant, extend preheating time, so that refrigerant temperature reaches indoor fan 12 and opened as early as possible Dynamic condition.
When start-up mode information for when being started with defrost pattern, schematic flow sheet as described in Figure 7, step 101 is according to opening Dynamic pattern information and/or the heat exchanger tube temperature of indoor set heat exchanger 11 determine the need for that refrigerant is carried out to preheat specific bag Include:
Step 301, the heat exchanger tube temperature T for detecting indoor set heat exchanger 11It is interior;The step be intended merely to during defrost Other steps keep the continuity of mark to be labeled as step 301, substantially identical with step 201;
Step 302, the heat exchanger tube temperature T for judging indoor set heat exchanger 11It is interiorWhether the 3rd preset temperature value T3 is less than, if It is the liquid refrigerants circulation side that step 102 is then performed while being run with intrinsic defrost pattern to indoor set heat exchanger 11 Liquid refrigerants is preheated, and otherwise performs step 303;
Step 303, with intrinsic defrost pattern run.
During defrost, if opening refrigerant heater 13 in advance when refrigerant temperature is relatively low, contracting is not only contributed to Short defrost process duration, additionally it is possible to which as early as possible reaching refrigerant temperature after defrost process terminates makes indoor fan 12 Entry condition, so that the time that the start-up course for shortening air conditioner expends, to start to heat room air ahead of time.Step 301 It can be performed after the startup of compressor 2.
Further, the liquid refrigerants of indoor set heat exchanger 11 is circulated while being run with intrinsic defrost pattern side During liquid refrigerants progress is pre-warmed, in addition to:
Step 304, the heat exchanger tube temperature T for judging indoor set heat exchanger 11It is interiorWhether more than the 4th preset temperature value T4, if It is then to perform step 104 ' liquid refrigerants heating of the stopping to the liquid refrigerants circulation side of indoor set heat exchanger 11, otherwise continues to add Heat;Wherein, the 4th preset temperature value T4 is more than the 3rd preset temperature value T3.Preferably, T1 < T3 < T2, T4 > T2.
The heat exchanger tube temperature T of embodiment machine heat exchanger 11 indoorsIt is interiorMore than the 4th preset temperature value T4 time controls refrigeration matchmaker Heater 13 stops heating, the energy consumption that can be saved during air conditioner defrost, and prevents refrigerant temperature too high to compressor Functional reliability impact.
During defrost, for natural mode defrost, with the always on refrigerant of the whole process of natural mode defrost Heater 13 and the part-time section unlatching refrigerant heater with natural mode defrost, control method of the invention are also wrapped Include:
Step 305, judge whether the heat exchanger tube temperature of outdoor unit heat exchanger 51 reaches default defrost end temp, if Then defrost process terminates.
After judging that defrost process terminates by step 305, then the control reversal valve 4 continued executing with step 104 is changed To heating mode is switched to, if the liquid refrigerants heating for side of still being circulated in the liquid refrigerants to indoor set heat exchanger 11, holds Row step 104 ' stop heating.
After the control commutation of reversal valve 4 switches to heating mode, it is put into temperature and judges flow, i.e., changed by indoor set The heat exchanger tube temperature T of hot device 11It is interiorJudge the opportunity for starting opportunity and the switching of the operational mode of indoor fan 12 of indoor fan 12, it is right Should be in step 201 to 207.Judge that the corresponding control method of two kinds of start-up modes of flow elements is similar on temperature.
A specific embodiment is given below, to illustrate that the air conditioner of the present invention starts control method, as shown in Figure 8 Schematic flow sheet.For the workflow of air conditioner substantially, after starting up runs, outdoor fan 52 starts, and passes through Compressor 2 starts after 30s, switches to heating mode after reversal valve commutation after 20s, outdoor fan 52 keeps operating.
(1) when air conditioner is started with heating mode:
If TRing>=20 DEG C, refrigerant heater 13 is opened while compressor 2 starts, by the first preset time t 1 (such as 20s) reversal valve commutates afterwards, and closes refrigerant heater 13.Now judge TIt is interiorWhether first preset temperature value T1 is reached (such as 35 DEG C), if not up to (TIt is interior35 DEG C of <) then making reversal valve, the second preset time t of continuous service 2 is (for example after commutation 5s), indoor fan is made to enter low wind shelves operational mode again afterwards.If reaching the first preset temperature value T1 (TIt is interior>=35 DEG C), then Determine whether TIt is interiorWhether more than the second preset temperature value T2 (such as 40 DEG C), if it exceeds the second preset temperature value T2 (TIt is interior≥ 40 DEG C), then control indoor fan 12 to be run according to setting wind shelves, setting wind shelves can be judged by controller according to environment temperature Go out, if not less than (35 DEG C≤T of the second preset temperature value T2It is interior40 DEG C of <), then control indoor fan 12 to be run with low wind shelves, After indoor fan 12 is with the low wind shelves preset time t 3 (such as 60s) of mode operation the 3rd, it can be directly switch into according to setting wind Shelves operation.
If TRing20 DEG C of <, control method and TRingIt is essentially identical at >=20 DEG C, it the difference is that only, due to indoor environment Temperature is relatively low, and the second preset time t 2 is extended, for example, is defined as 15s, while the 3rd preset time t 3 is extended, for example, is determined For 90s.
(2) when air conditioner is started with defrost pattern:
Start defrost pattern first, after the startup of compressor 2, judge TIt is interiorWhether the 3rd preset temperature value T3 is less than (for example 37 DEG C), if not less than (TIt is interior>=37 DEG C), then run with intrinsic defrost pattern, if less than (TIt is interior37 DEG C of <) then in defrost During open refrigerant heater 13, and continue to judge TIt is interiorWhether fourth preset temperature value T4 (such as 42 DEG C) is reached, if (T is reachedIt is interior>=42 DEG C) refrigerant heater 13 is then closed, otherwise (TIt is interior42 DEG C of <) continue to heat during defrost.With During these three situation defrosts, the temperature to the heat exchanger tube of outdoor unit heat exchanger 51 judges, if reached default Defrost end temp, then defrost terminates.
After defrost terminates, reversal valve 4 commutates, and closes refrigerant heater 13, referring next to what is started with heating mode Step is again to TIt is interiorJudged, to determine operation opportunity and the operational mode of indoor fan 12.Unlike, due to defrost pattern The temperature of lower refrigerant is lower, thus if when reversal valve 4 commutates TIt is interiorThe first preset temperature T1 is still not up to, then relative to system For heat pattern starts, it is possible to increase reversal valve 4, which commutates to the second preset time t 2 between indoor fan 12 starts, (such as to be increased For 45s).
According to another aspect of the present invention, additionally provide a kind of air conditioner and start control system, for performing above-mentioned each reality Apply the control method described in example.The advantage that the air conditioner starts control system and can reached refers to retouching in control method part State.
Finally, present invention also offers a kind of air conditioner, including the air conditioner starter described in above-described embodiment, or it is empty Device is adjusted to start control system.The air conditioner can pass through pre-warmed mode when to heat start and be started shooting with defrost pattern Refrigerant temperature is set quickly to raise, to start indoor fan in time after reversal valve commutation enters heating mode, it is to avoid offer a high price Pressure protection failure, reduces fault rate, unit is normally used, while improving the comfortableness heated.
