The setting for determining range is related with the type of compressor.
It is exemplified below the calculation of one of defrosting set temperature updated value.In the calculation, defrosting setting
The updated value of temperature are as follows:
T'If(t)=TIf(t)×[Δt1×a+H(t)×b]；
Wherein, T'IfIt (t) is updated defrosting set temperature, TIfIt (t) is the defrosting set temperature before update, Δ t1For
First duration, H (t) are heat efficiency value, and a, b are constant coefficient, wherein a is negative, and b is positive number.
Wherein, [Δ t1× a+H (t) × b] value range be [K1, K2], K1 is minimum value, and K1 < 1, K2 are most
Big value, and K2 > 1.As [Δ t1× a+H (t) × b] be less than K1 when, according to K1 value execute formula, as [Δ t1×a+H(t)×b]
When greater than K2, formula is executed according to K2 value.K1, K2 define the knots modification range of defrosting set temperature.
When the first duration detected value is in the first setting range and the calculated value of heat efficiency value is in the second setting range
When interior, setting:
[Δt1× a+H (t) × b]=1, it may be assumed that
T'If(t)=TIf(t), defrosting set temperature remains unchanged.
When the calculated value of heat efficiency value is lower than the minimum value of the second setting range, illustrate that frosting is serious, heats efficiency
Decline is calculated at this point, the calculated value of the detected value of the first duration, heat efficiency value is substituted into following formula, is obtained:
[Δt1×a+H(t)×b]>1；
If [Δ t1× a+H (t) × b] calculated value between [K1, K2], then by calculated value substitute into following formula calculating updated

T'If(t)=TIf(t)×[Δt1×a+H(t)×b]；
If [Δ t1× a+H (t) × b] calculated value is greater than K2, then takes K2 value, and it substitutes into calculate in following formula and obtains updated removes
White set temperature:
T'If(t)=TIf(t)×K2。
At this point, updated defrosting set temperature is higher than the defrosting set temperature before updating, removed so that air-conditioning enters in advance
White program begins to defrost when condenser coil temperature is higher, improves defrosting effect, reduces the influence to heat efficiency.
When the detected value of the first duration is greater than the maximum value of the first setting range, illustrate defrosting not exclusively, defrosting time
It is too long.It calculates, obtains at this point, the calculated value of the detected value of the first duration, heat efficiency value is substituted into following formula:
[Δt1×a+H(t)×b]>1；

T'If(t)=TIf(t)×[Δt1×a+H(t)×b]；
If [Δ t1× a+H (t) × b] calculated value is greater than K2, then takes K2 value, and it substitutes into calculate in following formula and obtains updated removes
White set temperature:
T'If(t)=TIf(t)×K2。
At this point, updated defrosting set temperature is higher than the defrosting set temperature before updating, removed so that air-conditioning enters in advance
White program begins to defrost when condenser coil temperature is higher, improves defrosting effect, shortens defrosting time.
When minimum value of the detected value of the first duration less than the first setting range, illustrate that defrosting time is too short, at this time
Frosting degree does not need to defrost immediately, and the temperature spot into defrosting program is excessively high, it is easy to meet defrosting program and enter item
Part, therefore cause frequently to defrost, reduce heating effect.Such as in coastal area, when outdoor environment temperature is lower, humidity can
Energy is larger, if defrosting set temperature is improper, when air-conditioning operates normally heating, can often trigger the condition for entering defrosting program
And frequently defrost, cause heating effect to decline.At this point, under the calculated value of the detected value of the first duration, heat efficiency value is substituted into
It calculates, obtains in formula:
[Δt1×a+H(t)×b]<1；
If [Δ t1× a+H (t) × b] calculated value between [K1, K2], then by calculated value substitute into following formula calculating updated
Defrosting set temperature afterwards, it may be assumed that
T'If(t)=TIf(t)×[Δt1×a+H(t)×b]；
If [Δ t1× a+H (t) × b] calculated value is less than K1, then takes K1 value, and it substitutes into calculate in following formula and obtains updated removes
White set temperature:
T'If(t)=TIf(t)×K1。
At this point, updated defrosting set temperature is removed lower than the defrosting set temperature before updating so that air-conditioning postpones entering
White program starts to defrost when condenser coil temperature is lower again, avoids frequently defrosting, and reduces the influence to heating effect.
The present embodiment is by setting coefficient a, coefficient b, the defrosting duration to defrost for the last time and the system currently once heated
Thermal energy valid value configure weight coefficient, the sum of the defrosting time of different weights and heat efficiency value to defrost set temperature size into
Row is adjusted, to adjust defrosting process, is prevented from entering defrosting program too early or too late, is caused frequently to defrost or defrosting is not exclusively made
At heating effect reduce.
Optionally, coefficient a, coefficient b can be obtained in the following way:
On the basis of determining the first setting range, the second setting range, a length of first setting range when first is determined
When some value, some value that heat efficiency value is the second setting range, substitute into following formula:
[Δt1× a+H (t) × b]=1,
Choose a, b value for meeting above formula.
Wherein, heat efficiency value can be calculated using calculation in the prior art and be obtained.Illustrate it herein
A kind of middle calculation method, in the method, according to the corresponding coefficients R n of current room temperature, the corresponding coefficient Nn of outdoor environment temperature,
Second duration (i.e. heating time) Δ t2The electric energy W of temperature increment Δ T and the compressor consumption of interior promotion is calculated, formula are as follows:
Optionally, can be per once outdoor environment temperature corresponding one with a coefficients R n corresponding per once current room temperature
Number Nn.
Further, the initial value for the set temperature that defrosts is multiple, the initial value correspondence of each defrosting set temperature
