Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the present invention is described in further detail, but not as a limitation of the invention.
Please refer to Fig. 1 and Fig. 2, embodiments provide a kind of air-conditioner outdoor unit standby controlling method, comprising: obtain outdoor environment temperature, oil temperature bottom oil temperature and oil eliminator bottom compressor; Obtain set temperature value, set temperature value comprises temperature upper limit and/or lowest temperature value; Compare the magnitude relationship bottom oil temperature, oil eliminator between oil temperature and set temperature value bottom outdoor environment temperature, compressor respectively; Whether duty is entered according to magnitude relationship determination electric heater unit.Such as, electric heater unit can be heat tape etc.
Like this, the present invention can according to the relation bottom oil temperature, oil eliminator bottom outdoor environment temperature, compressor between oil temperature and set temperature value, judge whether under working environment (such as different seasons etc.) at that time, need to start the reliability that electric heater unit enters duty guarantee compressor start.Therefore, by technique scheme, the unnecessary electricity auxiliary heat time can be avoided, thus reduce the stand-by power consumption of unit, thus more energy-conservation.
As shown in Figure 2, outdoor environment temperature A can fluctuate relative to temperature upper limit X and lowest temperature value Y.
Preferably, please refer to Fig. 2, as outdoor environment temperature is more than or equal to temperature upper limit, and bottom compressor bottom oil temperature and oil eliminator oil temperature be all more than or equal to the temperature of first predetermined value lower than temperature upper limit, then keep electric heater unit to be in off position.Usual the present embodiment is applicable to summer high temperature environment, and now, outdoor environment temperature is higher, and bottom compressor bottom oil temperature, oil eliminator oil temperature be also in higher value, therefore, do not need electric additional heat can ensure the reliability of compressor start.Especially, the first predetermined value is 2.
Preferably, please refer to Fig. 2, when being in transition season, if meet following three conditions simultaneously, then keeping electric heater unit to be in off position: (1) outdoor environment temperature is between temperature upper limit and lowest temperature value; (2) bottom compressor, bottom oil temperature and oil eliminator, oil temperature is all more than or equal to lowest temperature value; (3) outdoor environment temperature is in the state constantly declined.Now, although outdoor environment temperature is in the process constantly declined, but it is but between temperature upper limit and lowest temperature value always, and bottom compressor bottom oil temperature and oil eliminator oil temperature be all more than or equal to lowest temperature value, therefore, electric additional heat is not needed can to ensure the reliability of compressor start.
Preferably, please refer to Fig. 2, when being in transition season, if meet following four conditions simultaneously, then making electric heater unit enter duty: (1) outdoor environment temperature is between temperature upper limit and lowest temperature value; (2) bottom compressor, bottom oil temperature and oil eliminator, oil temperature is all less than lowest temperature value; (3) the compressor emergency shutdown time is more than or equal to the scheduled time (such as 1 hour); (4) outdoor environment temperature is in the state constantly declined.Now; although outdoor environment temperature is between temperature upper limit and lowest temperature value; but it is in the process constantly declined; and bottom compressor bottom oil temperature and oil eliminator oil temperature be all less than lowest temperature value, downtime for some time; therefore, the reliability needing that electric heater unit is entered duty just can ensure compressor start.
