Technical field
The invention belongs to air conditioner technical fields, and in particular to a kind of air conditioner defrosting control method.
Background technology
Air conditioner as a kind of equipment that can adjust indoor environment temperature, its working principle is that：It is being followed by refrigerant
Between endless tube road by the state of high voltage/low voltage/gaseous state/liquid convert make indoor environment temperature reduce or increase, i.e., from
From the perspective of indoor unit, air conditioner is in refrigeration or heating condition.When air conditioner heat-production is run, in certain humidity item
If outdoor coil temperature is too low to lead to frosting situation under part, and outdoor coil pipe used frosting can cause the heat exchange of outdoor heat exchanger to be imitated
Rate reduces, and influences the heating effect of air conditioner, reduces the comfort of indoor environment, influence user experience.Therefore, at air conditioner
In the case of heating condition, the outdoor coil pipe used progress to air conditioner is needed effectively to defrost in time.
Whether existing domestic air conditioner can judge air conditioner in knot in several ways in running heating operations
White state, such as go to judge whether to enter defrosting using run time+outdoor coil temperature.When judging that air conditioner is in frosting shape
After state, then air conditioner is set to enter defrosting mode, however this mode easily causes indoor temperature larger fluctuation.
Therefore, the present invention proposes a kind of new defrosting control method to reduce the shadow during defrosting to indoor temperature
It rings.

Technical solution through the invention, before air conditioner enters defrosting mode, by executing corresponding stored energy operation
Part energy is stored, during air conditioner defrosts, this portion of energy is supplemented to interior, when to effectively prevent defrosting
Room temperature fluctuation is excessive.
Description of the drawings
Fig. 1 is the main flow schematic diagram of the air conditioner defrosting control method of the present invention.
Specific implementation mode
To keep the embodiment of the present invention, technical solution and advantage more obvious, below in conjunction with attached drawing to the skill of the present invention
Art scheme is clearly and completely described, it is clear that and the embodiment described is a part of the embodiment of the present invention, rather than all
Embodiment.It will be apparent to a skilled person that these embodiments are used only for explaining the technical principle of the present invention, and
It is not intended to be limiting protection scope of the present invention.
As shown in Figure 1, the defrosting control method of the present invention includes the following steps：S110, the mistake run in air conditioner heat-production
Cheng Zhong, judges whether air conditioner meets defrosting condition；S120, if it is, before air conditioner enters defrosting mode, execute phase
The stored energy operation answered.By step S110-S120, part energy can be stored before air conditioner is defrosted, it is such
Words, during being defrosted, this portion of energy of storage can add in indoor heating capacity, subtract to a certain extent
Small air conditioner is to the influence of indoor temperature during defrosting, and room temperature fluctuation is excessive when so as to effectively prevent defrosting
Situation occur.
In step s 110, when judging whether air conditioner meets defrosting condition, those skilled in the art can select arbitrarily
Known judgment method, it is of the invention herein specific defrosting condition not to be defined.
In the step s 120, as an example, stored energy operation can be the running frequency for promoting compressor.For example, exist
Air conditioner enters before defrosting mode, and the running frequency of compressor is promoted 10-15hz.Skilled artisans appreciate that
Be that during air conditioner defrosts, indoor heating amount can reduce, and if enter defrost before compressor frequency is promoted after,
Part energy is stored in compressor, then during air conditioner defrosting, this portion of energy is supplemented to interior, to effectively
Room temperature fluctuation is excessive when preventing from defrosting.
As an example, stored energy operation can be the rotation speed of fan for reducing indoor unit and/or outdoor unit.For example, in sky
It adjusts device to enter before defrosting mode, the rotation speed of fan of indoor unit and/or outdoor unit is reduced into 40-60rpm.Preferably wind turbine is turned
Speed reduces 50rpm.So, before entering defrosting one is stored by reducing the rotation speed of fan of indoor unit and/or outdoor unit
Divide energy, then during air conditioner defrosting, this portion of energy is supplemented to interior, room temperature when to effectively prevent defrosting
It fluctuates excessive.
It will be readily appreciated by those skilled in the art that promotion pressure can be not only individually performed in the present invention before entering defrosting
The rotation speed of fan for reducing indoor unit and/or outdoor unit is individually performed in contracting machine running frequency；The two can also be performed simultaneously to carry
It rises compressor operating frequency and reduces the rotation speed of fan of indoor unit and/or outdoor unit.
As an example, the stored energy operation of the present invention can also be reduction throttle valve opening.For example, will air conditioner into
Before entering defrosting mode, throttle valve opening is reduced into 20-40 steps.So, it is opened before entering defrosting by reducing throttle valve
Degree storage part energy, during air conditioner defrosts, this portion of energy is supplemented to interior, when to effectively prevent defrosting
Room temperature fluctuation is excessive.
In conclusion technical solution through the invention, corresponding by executing before air conditioner enters defrosting mode
Stored energy operation stores part energy, and during air conditioner defrosts, this portion of energy is supplemented to interior, to effectively anti-
Room temperature fluctuation is excessive when only defrosting.
So far, it has been combined preferred embodiment shown in the drawings and describes technical scheme of the present invention, still, this field
Technical staff is it is easily understood that protection scope of the present invention is expressly not limited to these specific implementation modes.Without departing from this
Under the premise of the principle of invention, those skilled in the art can make the relevant technologies feature equivalent change or replacement, these
Technical solution after change or replacement is fallen within protection scope of the present invention.
