The invention discloses a refrigerating fan. The refrigerating fan comprises an electric fan, a refrigerating device and a humidifying device, the electric fan comprises a blowing end and a negative pressure end, the refrigerating device comprises a water tank and a refrigerating panel with ventilating openings, the refrigerating panel is located on the negative pressure end of the electric fan and is provided with a plurality of first refrigerating sheets and first water cooling heads attaching to the hot faces of the first refrigerating sheets, the cold faces of the first refrigerating sheets attach to the refrigerating panel, the water tank and the first water cooling heads is connected through a water channel circulation pipeline, and a water receiving disc used for receiving condensed water on the refrigerating panel and sending the condensed water to the humidifying device is arranged below the refrigerating panel. The problem that water in the water tank needs to be consumed continuously during refrigerating of the refrigerating fan is solved, and the refrigerating fan has the advantages of being good in refrigerating effect, capable of realizing humidifying effect, small in limitation and convenient to use.

The invention relates to the technical field of refrigerators, in particular to a control method for a refrigerator. The control method for the refrigerator comprises the steps that different control modes are operated according to different environment temperatures, refrigeration of a refrigerating chamber is conducted preferably when the environment temperature is smaller than a set environment temperature value as well as when the environment temperature is not smaller than the set environment temperature value and the temperature in a freezing chamber is smaller than a set freezing temperature value, and refrigeration of a temperature-variable chamber is conducted after refrigeration of the refrigerating chamber is completed; and whether refrigeration of the refrigerating chamber is needed or not is monitored while refrigeration of the temperature-variable chamber is conducted, and a throttling mechanism of the freezing chamber is controlled to be connected with a freezing refrigeration circuit when both refrigeration of the refrigerating chamber and refrigeration of the temperature-variable chamber are not needed, so that independent refrigeration of the freezing chamber is conducted. When the environment temperature is larger than the set environment temperature value and the temperature in the freezing chamber is not smaller than the set freezing temperature value, refrigeration of the refrigerating chamber is conducted after the refrigerator operates in the initial operating mode. According to the control method for the refrigerator, a compressor operates under a small load condition, so that damage caused by liquid impact is avoided, the refrigerating speeds of all the chambers are guaranteed, and the system stability is improved.

The invention discloses an air-cooling refrigerator air flue heating system and a control method thereof. The air-cooling refrigerator air flue heating system is characterized in that the system is installed on an air inlet of a refrigerating chamber of a refrigerator, and the position, close to a freezing chamber, of the refrigerator is provided with a compensation heater; and the compensation heater is used for obtaining a control structure of an air-cooling refrigerator air flue. The air-cooling refrigerator air flue heating system can avoid the risk that the refrigerator may not carry out refrigeration under the condition that the refrigerator is at low circumstance temperature.

The invention discloses a blind window device for an air conditioner and the air conditioner. The blind window device for the air conditioner comprises the blind window device matched with the installation space of an air-conditioning outdoor unit and a vane control motor used for being connected with the air conditioner, wherein the blind window device comprises a vane fixing plate, a plurality of vanes arranged on the vane fixing plate, and a connecting rod connected with one ends of the vanes, and the vane control motor is connected with the connecting rod. The air conditioner comprises an air-conditioning indoor unit used for being installed indoors, an air-conditioning outdoor unit installation cover used for being installed outdoors, an air-conditioning outdoor unit arranged inside the air-conditioning outdoor unit installation cover, and the blind window device for the air conditioner. By means of the blind window device for the air conditioner and the air conditioner, air energy after heat transfer is discharged out of the blind window device rapidly, the heat conversion efficiency and the energy efficiency ratio of the air-conditioning units are improved, power consumption is lowered, and the air-conditioning units operate normally.
