Abstract: The present disclosure provides a method and device for sharing control rights of appliances, a storage medium, and a server. The method includes that: a sharing request is received from a first user for sharing a control right of at least one appliance with at least one second user; and in response to the sharing request, a sharing operation of sharing the control right of the at least one appliance with the at least one second user is performed, so that both the first user and the at least one second user share the control right of the at least one appliance.

Abstract: Disclosed by the present disclosure is a refrigerant leak detection method and device for an air conditioner. The method includes: acquiring current operating parameters of an air conditioner and environment information of a surrounding environment of the air conditioner; inputting the current operating parameters and the environment information into a trained neural network model to obtain an amount of remaining refrigerant outputted by the neural network model; and determining, according to the amount of the remaining refrigerant, whether there is a refrigerant leak in the air conditioner. The present disclosure improves accuracy of detecting a refrigerant leak in the air conditioner by means of an artificial neural network algorithm.
