Problems solved by technology

[0003] At present, the commonly used defrosting mode is the four-way valve reversing mode. The system is switched to the refrigeration cycle, the internal and external fans are turned off, and the high-temperature refrigerant discharged from the compressor directly enters the condenser. The high-temperature refrigerant defrosts the condenser and comes out of the condenser The low-temperature refrigerant passes through the indoor unit, and although the indoor fan is turned off, the heat transfer through radiation causes large fluctuations in the indoor ambient temperature, which seriously affects the user's comfort experience.

no. 1 example

[0044] The present invention provides an air conditioner 1, which is used to ensure that when the air conditioner 1 is in a defrosting mode, the indoor temperature will not be affected too much and the user's comfort will not be affected. see figure 1 , is a block diagram of the circuit structure of the air conditioner 1 provided by the embodiment of the present invention. The air conditioner 1 includes: a memory 3 , a processor 2 , a parameter detection module 4 , a compressor 5 and a defrosting control device 6 . Wherein, the processor 2 is electrically connected to the memory 3 , the parameter detection module 4 and the compressor 5 . The defrosting control device 6 includes at least one device that can be stored in the memory 3 in the form of software or firmware.

[0045] Wherein, the memory 3 can be used to store software programs and units, such as the program instructions / units corresponding to the defrosting control device 6 and the method in the embodiment of the p...

[0051] The embodiment of the present invention provides a defrosting control method, which is applied to the air conditioner 1 to ensure that when the air conditioner 1 is in the defrosting mode, the indoor temperature will not be affected too much, and the user's comfort will not be affected. see figure 2 , is a flow chart of the defrosting control method provided by the embodiment of the present invention. The defrosting control method includes:

[0052] Step S201: Determine whether the air conditioner 1 satisfies the conditions for entering the defrosting mode, if yes, execute step S202; if not, execute step S201 again.

[0053] For example, when the air conditioner 1 is in the heating high wind gear operating state, the defrosting is performed only when the difference between the current evaporator temperature TE and the current indoor temperature TR is less than the preset defrosting temperature TH (that is, the air conditioner 1 operates in the high wind gear. The def...

[0077] see image 3 , image 3 A functional block diagram of a defrosting control device 6 provided by a preferred embodiment of the present invention. It should be noted that the defrosting control device 6 provided in this embodiment is applied to the air conditioner 1, and its basic principles and technical effects are the same as those of the above-mentioned embodiments. , you can refer to the corresponding content in the above-mentioned embodiments. The defrosting control device 6 includes: a judgment unit 7 , a target temperature value determination unit 8 , a parameter acquisition unit 9 , a control unit 10 and a working mode switching unit 11 .

[0078] Wherein, the judging unit 7 judges whether the air conditioner 1 satisfies the condition for entering the defrosting mode.

[0079] It can be understood that, in a preferred embodiment, the judging unit 7 can be used to execute step S201.

[0080] The target temperature value determination unit 8 is used to determin...

Abstract

The invention provides a method and a device for controlling defrosting and an air conditioner, and relates to the technical field of air conditioners. The method and the device comprise the followingsteps of when the air conditioner meets the frosting mode entering condition, setting the sum of a preset first target temperature value and a preset temperature change quantity as a second target temperature value, acquiring the current maximum running frequency, controlling a compressor to run at the current maximum running frequency, acquiring the indoor temperature value and the running duration of the compressor at the current maximum running frequency, and entering the frosting mode when the indoor temperature value or the duration meets the preset condition; before the frosting mode enters, increasing the indoor temperature, so that after the air conditioner enters the frosting mode, the indoor temperature is reduced at the temperature higher than the setting temperature of a user,but is not reduced to the temperature not excessively lower than the setting temperature of the user, thereby reducing the influence to the comfortability of the user by the frosting.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a defrosting control method, device and air conditioner. Background technique [0002] When the daily air conditioner is in heating operation, the condenser of the outdoor unit absorbs heat continuously, and the water vapor in the air will condense on the fins of the condenser to form frost. When the frost layer reaches a certain thickness, it will affect the heat exchange effect of the outdoor unit, so the heating It will defrost once after running for a period of time. [0003] At present, the commonly used defrosting mode is the four-way valve reversing mode. The system is switched to the refrigeration cycle, the internal and external fans are turned off, and the high-temperature refrigerant discharged from the compressor directly enters the condenser. The high-temperature refrigerant defrosts the condenser and comes out of the condenser The low-temperature refrigera...
