The technical problems in the prior art of the poor reliability of a compressor and the large system noise which are easily caused by long-term low-frequency operation of the compressor are solved.

Abrégé

The present invention relates to the technical field of air fragrance conditioning, and specifically provides a control method for an air fragrance conditioner, and an air fragrance conditioner, aiming at solving the problem of physical discomfort caused by pungent fragrance smelt by a user when returning indoors because existing air fragrance conditioners can only release fragrance but cannot adsorb the fragrance. The control method of the present invention comprises: after a fragrance releasing agent adjustment member and a fan are started, acquiring an actual indoor fragrance concentration; determining whether there is a person indoors; and when a determination result indicates that there is no person indoors and the duration of an empty state reaches a preset time, selectively controlling the operation of the fragrance releasing agent adjustment member and/or the fan, so as to reduce the actual indoor fragrance concentration to a preset fragrance concentration. In this way, when a person enters the room again, the person will not feel that the fragrance is pungent due to the fragrance concentration difference between indoors and outdoors, thereby avoiding the physical discomfort.

Abrégé

Provided in the present application is a refrigerator. The refrigerator comprises: a body, which is provided with at least one magnetic-field freshness-keeping compartment; a magnetic-field generation apparatus, which is used for generating a magnetic field in the storage space of the magnetic-field freshness-keeping compartment; and a refrigeration system, which performs refrigeration on the magnetic-field freshness-keeping compartment, wherein the magnetic-field generation apparatus is configured to make the intensity of the magnetic field in the storage space be greater than or equal to 10 Gauss and less than or equal to 100 Gauss, and the refrigeration system is configured to make the temperature in the storage space be higher than or equal to -10 degrees centigrade and lower than or equal to 0 degrees centigrade, or the magnetic-field generation apparatus is configured make the intensity of the magnetic field in the storage space be greater than or equal to 5 Gauss and less than or equal to 40 Gauss, and the refrigeration system is configured to make the temperature in the storage space be higher than or equal to -30 degrees centigrade and lower than or equal to -15 degrees centigrade. In this way, food can be refrigerated at a sub-zero temperature, or the situation where large ice crystals are generated in food when being frozen is ameliorated, thereby improving the storage effect.
