Automatic cleaning control method and device for air conditioner
InactiveCN110887155ALittle impact on comfortImprove frosting efficiencyMechanical apparatusLighting and heating apparatusProcess engineeringMechanical engineering
The invention discloses an automatic cleaning control method and device for an air conditioner, and belongs to the field of air conditioner control. According to the automatic cleaning control methodand device for the air conditioner, whether condensate water on a heat exchanger reaches a set standard or not is judged through detecting of air humidity; when the condensate water on the heat exchanger reaches the set standard, the heat exchanger is self-cleaned; otherwise, control over condensation water generation is carried out, and after generation of the condensation water is completed, theheat exchanger is self-cleaned again. According to the automatic cleaning control method and device for the air conditioner, a frosting link is conducted only after sufficient condensation water is generated on the heat exchanger, so that the frosting efficiency is higher; and meanwhile, the frosting speed is further accelerated through controlling the angle of an air guide plate, so that less influence is caused on using comfort for users, and much intelligence is achieved.

The air conditioner comprises a refrigerant circulation system and a solution circulation system, wherein the self-cleaning control method comprises the following steps that the frequency of a compressor is reducedunder the heating working condition, a four-way valve is subjected to reversing, the frequency of the compressor is raised, the opening degree of an electronic expansion valve is reduced, so that thevoltage of an indoor solution film and the voltage of an outdoor solution film are raised, and therefore, an indoor heat exchanger is frosted. After the indoor heat exchanger is frosted, the electronic expansion valve is turned off, an electromagnetic valve at the low pressure side of the compressor is turned off after a preset time, and the indoor heat exchanger is heated, so that the indoor heat exchanger is subjected to defrosting cleaning. According to the self-cleaning control method, the self-cleaning efficiency of the indoor heat exchanger can be improved, and the experience of a useris improved.

Frost inducing device for refrigerator and refrigerator
ActiveCN105526763AImprove frost-inducing effectLarge coverage areaLighting and heating apparatusDefrostingFrostWater vapor
The invention relates to a frost inducing device for a refrigerator and the refrigerator. In particular, the invention provides the frost inducing device for the refrigerator; and the frost inducing device comprises a frost inducing plate and a first grid plate. The frost inducing plate is configured to gather water vapor and allow the water vapor to condense to frost. The first grid plate is bonded on a frost inducing surface of the frost inducing plate, and is provided with multiple through holes for allowing passing of the water vapor to divide the frost inducing surface of the frost inducing plate into multiple frost inducing areas, so that the gathering speed of the water vapor on the frost inducing plate is quickened, the water vapor gathering efficiency on the frost inducing plate is improved, the frosting is easier on the frost inducing plate, and the frost inducing effect of the frost inducing device is improved. The invention further provides the refrigerator; the refrigerator comprises a refrigerator body for limiting a storage space inside, a door body for opening and / or closing at least part of the storage space and the frost inducing device; and the frost inducing device is detachably arranged on the refrigerator body or the door body to induce the water vapor in the storage space to condense to form frost on the frost inducing device.

The invention belongs to the technical field of air conditioners, and provides a self-cleaning control method for the air conditioner. The method aims to solve the problems that in general, an existing self-cleaning control mode of the air conditioner is low in frosting speed, so that the whole self-cleaning time is long, and the normal experience of a user is influenced. The air conditioner comprises a cold medium circulation system and a solution circulation system formed by an indoor solution film, an outdoor solution film, a liquid pump and a liquid storage box; and the self-cleaning control method comprises the following steps that under a refrigeration working condition, the frequency of a compressor is reduced and a four-way valve is reversed; the frequency of the compressor is raised and the rotating speed of the liquid pump is raised so as to frosting an outdoor heat exchanger; after the outdoor heat exchanger is frosted, an electronic expansion valve is closed firstly, and then a solenoid valve on the low-pressure side of the compressor is closed after a preset period of time; and the outdoor heat exchanger is heated so as to defrosting and cleaning the outdoor heat exchanger. The method can improve the efficiency of self-cleaning on the outdoor heat exchanger and improve the user experience.

The invention belongs to the technical field of air conditioners, and provides a self-cleaning control method for an air conditioner to solve the problems that a self-cleaning control mode of an existing air conditioner is generally low in frosting speed, and consequently the whole self-cleaning time is long, and the normal experience of a user is influenced. The air conditioner comprises a refrigerant circulating system and a solution circulating system which is composed of an indoor solution film, an outdoor solution film, a liquid pump and a liquid storage tank. The self-cleaning control method comprises the steps: under the working condition of refrigeration, the frequency of a compressor is decreased, and a four-way valve is reversed; the frequency of the compressor is increased, thevoltage of the indoor solution film and the voltage of the outdoor solution film are increased, and thus an outdoor heat exchanger is frosted; after the outdoor heat exchanger is frosted, an electronic expansion valve is closed firstly, and then a solenoid valve on the low-voltage side of the compressor is closed after the preset time; and the outdoor heat exchanger is heated, and thus the outdoorheat exchanger is subjected to frosting cleaning. The self-cleaning efficiency of the outdoor heat exchanger can be improved, and the user experience is improved.
