Description

Window type air conditioner and control method thereof
Technical Field
The invention relates to the technical field of air conditioners, in particular to a window type air conditioner and a control method thereof.
Background
The split household air conditioner in the current market has an evaporator self-cleaning function, and the principle is briefly introduced: when the evaporator needs to be cleaned, an indoor side fan of the split air conditioner is stopped, and the compressor and the outdoor side fan normally operate, so that the indoor side evaporator is extremely low in air side heat exchange efficiency, the evaporation temperature is very low and is far lower than the saturation temperature corresponding to humid air under the current pressure, moisture in the air can be condensed on fins of the indoor side evaporator to be liquefied, and water condensed on the evaporator can be condensed into ice along with the reduction of the evaporation temperature. After freezing to a certain degree, the exhaust heat of the compressor is hit to the frozen fin coil through the four-way reversing valve, the ice is quickly melted into water in a short time, and the fan is started to blow off dirty objects on the fins. In summary, self-cleaning is roughly divided into three stages of condensation, frosting and defrosting.
The existing window type air conditioner cannot realize respective shutdown of indoor and outdoor because of a single motor, if self-cleaning is to be realized, an indoor fan does not stop rotating, but the air quantity needs to be blocked so as to reduce the heat exchange quantity, thereby realizing frosting, but obviously, the blocking of the air quantity also blocks the natural circulation of outside and inside air, so that the evaporator has less condensation and thinner frosting in a condensation stage; in the market, window machines are poor in heating capacity, generally are single-cold-mode machines and only have a refrigerating function, so that rapid defrosting cannot be realized. If the evaporator frosts more thickly, even if the motor is turned on, wind cannot pass through the evaporator, so that the evaporator frosts more slowly.

The defrosting stage comprises the following steps: the air exchange opening and closing mechanism 8 is controlled to open the air exchange duct, so that outdoor hot air enters the room to improve defrosting efficiency.
In this embodiment, the working process of the air conditioner in the self-cleaning mode mainly includes three stages that are sequentially performed: and detecting whether the whole machine can reach a frosting state, and entering a frosting stage of the indoor heat exchanger 4 and a defrosting stage of the indoor heat exchanger 4. In the stage of the indoor heat exchanger 4 frosting, the indoor heat exchanger 4 of the indoor unit can be frozen and frosted; in the defrosting stage of the indoor heat exchanger 4, the condensed frost of the indoor heat exchanger 4 in the previous defrosting stage is melted, impurities such as dust and the like can be separated from the indoor heat exchanger 4 along with the melted condensed water, and the cleaning treatment of the indoor heat exchanger 4 is completed.
Specifically, if the air conditioner is in a self-cleaning mode, when the air conditioner detects whether a condensation state can be achieved, the motor 7 cannot be directly closed due to the single motor 7, if the motor 7 is closed, outdoor heat exchange is extremely poor, the window type air conditioner can skip load protection, and the event is usually very fast, and is several seconds or tens of seconds. The indoor switch mechanism is required to be closed, namely the air outlet duct 12 is closed, and air is blocked from entering the evaporator from the source, so that the temperature of the evaporator is reduced to achieve the condensation condition, but the indoor switch mechanism is not limited to closing the air outlet duct 12, and the air inlet duct 11 can also be closed or blocking the circulation of air in the duct, and any mode can be adopted, so that the evaporator can make the cold energy lost as little as possible in a relatively closed environment to reduce the heat exchange of the evaporator, or the air cannot normally circulate to achieve the purpose of reducing the heat exchange of the evaporator. The operation of the indoor heat exchanger 4 for condensing and frosting ice is realized by adjusting the operation parameters of components such as a fan, a panel or a shell, if the air does not reach the condensation state, the air exchange duct is opened, and the outdoor humid air is introduced into the volute 2, so that the evaporator can condense and frost ice.
The evaporator temperature is detected and defrosting operation is possible if the evaporator temperature is below a certain set value. The evaporator temperature point detection can adopt a temperature sensing bulb, a common window type air conditioner is provided with anti-freezing protection, the temperature sensing bulb and the anti-freezing protection temperature sensing bulb can share one temperature sensing bulb, the protection temperature points are different when entering different modes, or a temperature sensing bulb can be used for controlling a self-cleaning mode independently, the self-cleaning defrosting temperature point is lower than the anti-freezing protection temperature point, the priority is higher than the anti-freezing protection, namely the self-cleaning is started, the anti-freezing protection is not detected, the temperature point is reached, and the like on the evaporator are stopped.
Under the condition of defrosting, except that the operation that each part is opposite when frosting, for example, open indoor switch mechanism, the evaporimeter frosting is thicker this moment, and the air can't pass the evaporimeter, and single cold window formula air conditioner does not have the heating condition again, and the wind channel of changing is opened, introduces outdoor hot-air and washes away the evaporimeter and makes the evaporimeter change the frost fast, detects the evaporimeter temperature point during the defrosting, reaches the uniform temperature, will open the next time and frosts the flow, gets into several cycles and will end the automatically cleaning.
Trade wind closing mechanism 8 and include actuating mechanism and door subassembly, trade the size of wind mechanism and do not have the restriction, can design and well baffle be equally big, replace the baffle even, the slide rail setting is on the chassis this moment, and it is easier like this to change the motor for the window type air conditioner, opens the new trend door and can take out the motor together with centrifugal fan blade, need not pull down the upper cover plate earlier, pulls down the evaporimeter, takes off centrifugal fan blade, can take out the motor.
Exemplary embodiments of the present disclosure are specifically illustrated and described above. It is to be understood that the present disclosure is not limited to the precise arrangements, instrumentalities, or instrumentalities described herein; on the contrary, the disclosure is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the appended claims.
