The invention provides an intelligent ash deposition maintenance control method and system for a condenser, a refrigerator and a terminal. The intelligent ash deposition maintenance control method for a condenser of a refrigerator comprises the following steps: after detecting that a compressor is started up, detecting the pressure difference delta p at an air supply opening and an air discharge opening of the condenser every preset time, and detecting the ambient temperature tw of a place where the refrigerator works; determining the ash deposition amount gamma n of the condenser according to the pressure difference delta p and the ambient temperature tw; and sending the ash deposition amount gamma n to a terminal. According to the intelligent ash deposition maintenance control method for the condenser of the refrigerator, the purpose that the terminal judges whether ash deposition of the condenser is cleaned according to the ash deposition amount gamma n is achieved, so that maintenance personnel can clean ash deposition of the condenser, accordingly, the heat exchange efficiency of the condenser is improved, meanwhile, the energy consumption of the refrigerator cannot be increased, and the use satisfaction of a user to the refrigerator is improved. Furthermore, the phenomenon that corrosion of the condenser is quickened by too much ash deposition of the condenser is avoided, the service life of the condenser is prolonged, and further, the use satisfaction of the user to the refrigerator is improved.

The invention provides a condensation prevention method and device for refrigeration equipment. The condensation prevention method comprises the steps: detecting the humidity of the external environment of the refrigeration equipment; judging whether the humidity is less than the preset humidity threshold value or not; if yes, setting the turn-on temperature of a storage room as first turn-on temperature, setting the turn-off temperature of the storage room as first turn-off temperature, and setting the speed of a compressor as first speed; if not, setting the turn-on temperature of the storage room as second turn-on temperature, setting the turn-off temperature of the storage room as second turn-off temperature, and setting the speed of the compressor as second speed. Thus, the refrigeration cycle of a refrigeration system is constant, the operating time of the compressor is prolonged, and the stop time of the compressor is shortened. The condensation prevention method can avoid long-time condensation, thereby overcoming the defects that the paint film of a box body is shed largely, the corrosion of the box body is accelerated, the service life of the refrigeration equipment is shortened, and the refrigeration effect of the refrigeration equipment is influenced.

A refrigerator (100), comprising: a refrigerator body (10), a storage space and a compressor cabin (11) being defined therein, the compressor cabin (11) being provided on the rear side of the bottom of the refrigerator body (10), the front side of the compressor cabin (11) being an air duct, and an air inlet (111) being formed in the compressor cabin (11) to be communicated with the air duct; door bodies (21, 22), pivotally provided on the front surface of the refrigerator body (10) so as to allow a user to open or close the storage space; a refrigerating system, configured to provide cooling capacity to the storage space; and an ash deposition disc (40), detachably provided on the air duct, communicated with the air inlet (111) of the compressor cabin (11), and configured to intercept dust in the air entering the air duct so as to enable clean air to enter the compressor cabin (11), thereby resolving the problem of ash deposition of the refrigerating system in the compressor cabin (11). The ash deposition disc (40) is detachably provided on the air duct, so that the user can conveniently draw out and clean the ash deposition disc regularly, and the use convenience of the user is improved.

The invention belongs to the field of windows and doors of fixed constructions, and particularly discloses a novel fire-proofing escape door with a cooling effect. The novel fire-proofing escape door comprises a door frame and a door body, which are made of fire-proofing core plates, wherein a door handle is respectively arranged on indoor side and outdoor side of the door body; a fire-extinguishing and cooling device is arranged on one side of each door handle, and comprises a cylinder body; a separator is arranged in each cylinder body, one end of each separator is hinged in the respective cylinder body, the other end of each separator is adhered with glue, and each separator is adhered to the inner wall of the respective cylinder body through the first glue; each cylinder body is separated into a first chamber and a second chamber by virtue of the respective separator, each first chamber is filled with aluminum sulfate, and each second chamber is filled with sodium bicarbonate; a nozzle is formed in the side wall of the top of each cylinder body, and is filled with second glue for sealing; the melting point of the second glue is higher than that of the first glue; and the nozzle is just aligned to each door handle. By adopting the scheme, the temperature of the door handles can be reduced when a fire disaster happens, so that the escape rate of people can be improved.

The invention discloses a refrigerator control method and the refrigerator. The control method includes: starting a cooling fan after the evaporator completes defrosting; turning off the cooling fan after the cooling fan runs for a first preset time; controlling The compressor and the refrigerating fan are turned on successively to perform refrigerating work. In the technical solution of the present invention, after the defrosting is completed, the cooling fan is first turned on to shake off the water droplets on the cooling fan, so as to prevent the water droplets from freezing on the cooling fan, thereby avoiding the power consumption and noise of the system caused by freezing on the cooling fan When the compressor is turned on to cool the evaporator, the cooling fan is turned off, so as to avoid the hot air in the chamber being blown into the freezer and cold room of the refrigerator by the fan when the compressor starts to cool, which will affect the performance of the refrigerator. Cooling effect.

The invention discloses a transformer and belongs to the technical field of transformers. A transformer, comprising an installation box, further comprising: an electrical assembly detachably connected to the installation box, wherein the electrical assembly includes a casing, and a heat sink is arranged in the casing, and a heat sink is fixedly connected to the heat sink. Windings, the top of the housing is provided with terminals, the terminals are electrically connected to the windings; the shunt box fixedly connected to the inner wall of the housing is used to spray dry powder to the windings; the shunt box arranged in the installation box Ring; the connecting block arranged in the installation box; the present invention automatically uses dry powder to extinguish the fire of the electrical components when they spontaneously ignite, preventing the electrical components from continuing to burn and causing a fire, and by collecting rainwater, the rainwater is used to reduce the temperature inside the installation box , so as to reduce the possibility of spontaneous combustion of electrical components, and the water in the water chamber can absorb the vibration waves generated by the electrical components, thereby reducing noise.
