Second embodiment
The embodiment of the invention provides a kind of defrosting control methods, are applied to air conditioner 1, for guaranteeing that air conditioner 1 is in
When defrost pattern, room temperature will not be excessively influenced, influences the comfort of user.Referring to Fig. 2, being provided for the embodiment of the present invention
Defrosting control method flow chart.The defrosting control method includes：
Step S201：Judge whether air conditioner 1 meets the condition into defrost pattern, if so, thening follow the steps S202；
If it is not, then re-executeing the steps S201.
For example, when air conditioner 1 is in and heats high wind file operating status, current evaporator temperature TE and current indoor temperature
The difference of TR is less than default defrost temperature TH and just carries out defrost (i.e. defrost condition of the air conditioner 1 when high wind file is run is TE-TR
<TH)；When air conditioner 1 is in wind file operating status in heating, the difference of current evaporator temperature TE and current indoor temperature TR
Just carrying out defrost less than default defrost temperature TM, (i.e. defrost condition of the air conditioner 1 in the operation of middle wind file is TE-TR<TM)；When
When air conditioner 1 is in heating low wind file operating status, the difference of current evaporator temperature TE and current indoor temperature TR are less than pre-
If defrost temperature TL just carries out defrost, (i.e. defrost condition of the air conditioner 1 in the operation of low windscreen is TE-TR<TL).
It should be noted that above are only citing, the condition into defrost pattern can also be other, not do herein specific
Limitation.
Step S202：The sum of presetting first object temperature value and presetting temperature variation is determined as the second mesh
Mark temperature value.
Wherein, presetting first object temperature value is the desired temperature of user's self-demand and setting；By will be pre-
The sum of the first object temperature value of setting and presetting temperature variation is determined as the second target temperature value, so that air conditioner 1
Target temperature value increase, so that room temperature be made to increase, to carry out standard in advance for the defrost pattern that air conditioner 1 will enter
It is standby.
In a kind of preferred embodiment, presetting temperature variation is 2 DEG C.It should be noted that by a large amount of real
Verify bright, under normal circumstances, air conditioner 1, which will lead to indoor temperature value into defrost pattern, reduces by 2 DEG C, therefore by presetting temperature
Spending variable quantity is 2 DEG C, can be bonded the demand of user as far as possible, improve the experience sense of user.Certainly, in other embodiments,
Presetting temperature variation may be other numerical value, be not particularly limited herein.
Step S203：Obtain current maximum frequency of operation.
It should be noted that current maximum frequency of operation is the maximum frequency that compressor 5 can be run.
Step S204：Compressor 5 is controlled to run according to current maximum frequency of operation.
Make compressor 5 with the operation of current maximum frequency of operation, so as to quickly increase indoor temperature value.
Step S205：It obtains indoor temperature value and compressor 5 is in the state run according to current maximum frequency of operation
Duration.
Since compressor 5 according to current maximum frequency of operation operation, just start timing, with obtain compressor 5 be in press
According to the duration of the state of current maximum frequency of operation operation.
Meanwhile indoor temperature value can be acquired by temperature sensor.
Step S206：Judge whether indoor temperature value or duration meet preset condition, if so, thening follow the steps
S207；If it is not, then re-executeing the steps S205.
Specifically, judgment mode includes two kinds：
The first：Judge whether indoor temperature value is greater than or equal to the second target temperature value.
By judging whether indoor temperature value is greater than or equal to the second target temperature value, to directly determine indoor temperature value
Whether second target temperature value is had reached.
Second：Judge whether the duration is greater than or equal to presetting time threshold.
By judging whether the duration is greater than or equal to presetting time threshold, to determine indoor temperature value indirectly
Whether second target temperature value is had reached.
Since outer machine frosting heat transfer effect is poor at this time, presetting time threshold is unsuitable too short, otherwise room temperature
Value is not readily reachable by the second target temperature value；It is run again due to compressor 5 according to current maximum frequency of operation simultaneously, heat exchange efficiency
Relatively high therefore presetting time threshold is also unsuitable too long, and otherwise indoor temperature value can easily exceed the second target temperature
Value.Therefore, in a kind of preferred embodiment, which is 5 minutes.
It is to be appreciated that being greater than or equal to this condition of the second target temperature value or when lasting when indoor temperature value meets
When time meets more than or equal to any one condition of presetting time threshold, it is believed that indoor temperature value or duration
Meet preset condition.
In addition, time threshold also limits the time that air conditioner 1 causes indoor temperature value to rise, increase indoor temperature value
It is unlikely to excessive, influences the experience sense of user.
Step S207：Into defrost pattern.
When indoor temperature value is greater than or equal to the second target temperature value or the duration is greater than or equal to presetting
Between threshold value when, indoor temperature value has reached the second target temperature value, at this time enter defrost pattern, can be avoided air conditioner 1 into
After entering defrost pattern, caused by indoor temperature value and the set temperature value of user have big difference caused by uncomfortable problem.
