Method for sterilization of air conditioner and air conditioner

The invention relates to a method for sterilization of an air conditioner and the air conditioner. The method comprises the steps that the air conditioner is started, an indoor unit is in a heating operation mode, and the surface temperature T0 of a heat exchanger of the indoor unit is increased to be larger than a sterilization temperature threshold T, and is kept for the time t. According to the invention, after the air conditioner is started, the indoor unit conducts heating operation, and the surface temperature of the heat exchanger of the indoor unit is increased to be larger than the sterilization temperature threshold, and is kept for a certain time, so that bacteria in the air conditioner can be killed, and the cleanliness of the indoor unit of the air conditioner can be improved. In addition, in order to improve the sterilization effect of the air conditioner, before the indoor unit conducts heating operation, water can be added to the surface of the heat exchanger of the indoor unit, and/or the indoor unit can be in a dehumidification mode so as to generate condensation water on the surface of the heat exchanger of the indoor unit; and then the added water or the generated condensation water is converted into high-temperature steam in the indoor unit when the indoor unit conducts heating operation, and rapid sterilization is achieved.

Non-thermal sterilization method for apple cloudy juice

The invention discloses a liquid food novel non-thermal sterilization method, in particular a non-thermal sterilization method of cloudy apple juice which belongs to the food processing technology field. The technical scheme includes adopting the aseptic operation to send the cloudy apple juice into a reaction vessel and adopting pulse type carbon dioxide with high density for the sterilization. The concrete operation step is: firstly, pumping carbon dioxide with high density into the reaction vessel; secondly, treating for a certain period at the set temperature and pressure condition; thirdly, releasing the carbon dioxide after the treatment to lower the pressure in the reaction vessel to the normal pressure; fourthly, operating the steps from the first to the third repeatedly for more than two times for the pulse type carbon dioxide with high density treatment. The killing effect of Escherichia coli in the cloudy apple juice which is processed in the invention can achieve the result of lowering at least five logarithms to satisfy the commercial aseptic requirement. Compared with the present non-thermal sterilization method, the invention has more obvious sterilization effect and can shorten the treatment time and save energy. The invention has the advantages of low processing temperature, energy saving and environmental protection and can maintain the good flavor of the cloudy apple juice.
