Abstract: The disclosure provides a method for controlling air conditioner temperature. The method comprises the following steps: acquiring the operating mode of an air conditioner at the current moment, wherein the operating mode comprises refrigerating mode and heating mode; acquiring the historical duration of operation of the air conditioner in the operating mode; judging whether the historical duration is greater than the first set duration or not; and if so, setting the current operating temperature of the air conditioner based on the set operating temperature and the optimal reference temperature of the air conditioner at the first specified historical moment. The method has the advantages that the current operating temperature can be set according to the historical operating temperature of the air conditioner, and body feeling delay caused by the fact that a user has to manually set the temperature is avoided.

Abstract: The present invention discloses a bladeless cooling fan, which is used to solve the problem of poor use experience of the fan in the prior art. The bladeless cooling fan comprises: a fan body, comprising an air inlet; a water cooling component, which is provided together with the air inlet, wherein the water cooling component cools the air that enters the fan body via the air inlet; a wind wheel component, which is accommodated in the fan body and arranged to generate air flow; an air outlet component, which is installed on the fan body, wherein the air outlet component is arranged to receive the air flow from the fan body and guide the air flow to be ejected to the set direction.

Abstract: An evaporative cooler includes a first heat exchanger, a first coolant storage, a second coolant storage, and a first airflow drive. The first heat exchanger is capable of cooling a coolant flowing through the first heat exchanger, and cooling an air flowing through the first heat exchanger by way of the cooled coolant. The first coolant storage forms a first coolant circulating path with the first heat exchanger and provides the coolant to the first heat exchanger. The second coolant storage forms a second coolant circulating path with the first coolant storage and is capable of supplementing the first coolant storage with the coolant. The capacity of the second coolant storage is larger than that of the first coolant storage. The first airflow drive cooperates with the first heat exchanger to direct and eject the air flowing through the first heat exchanger.
