Floor-standing air conditioner, and method and device for controlling outlet air temperature of floor-standing air conditioner, and storage medium

Abstract

The invention discloses a floor-standing air conditioner, and a method and device for controlling the outlet air temperature of the floor-standing air conditioner, and a storage medium. An indoor unitof the floor-standing air conditioner comprises a shell of which the rear side wall is provided with an air inlet, and the front side wall of the shell is provided with an air outlet; the air outletextends up and down, and the shell is internally provided with an air duct communicating with the air inlet and the air outlet; the shell is internally provided with a heat exchanger, and the air outlet is divided into N air guide areas in the up-and-down direction; each air guide area is provided with a plurality of air guide units, and the heat exchanger comprises N heat exchange partitions divided according to a refrigerant flow path; and the N heat exchange partitions are distributed correspondingly to the N air guide areas, and the N is a positive integer which is greater than 1. The method comprises the steps of collecting the temperature of the N heat exchange partitions of the heat exchanger; comparing the temperature values of the N heat exchange partitions; and regulating the airguide angles of the air guide units of the N air guide areas according to the temperature values of the N heat exchange partitions, so that the outlet air temperature of the N air guide areas is uniform. According to the floor-standing air conditioner, and the method and device, the outlet air temperature is uniform, and the comfort is improved.

Description

technical field [0001] The invention belongs to the technical field of air conditioners, and in particular relates to a method for controlling the outlet air temperature of a cabinet-type air conditioner, a device for controlling the outlet air temperature of the cabinet-type air conditioner, a cabinet-type air conditioner, and a storage medium. Background technique [0002] For cabinet-type air conditioners such as round cabinets, the air outlet will be set relatively long, which will easily cause the temperature difference at the air outlet to increase. Especially when the evaporator is a single row, it is difficult to ensure uniform temperature at the air outlet. The temperature of the upper air outlet is 45°C, while the temperature of the lowermost air outlet is 35°C, which makes the human body less comfortable. [0003] In the related technology, the large temperature difference is generally avoided by adjusting the refrigerant branch of the evaporator to be very unifor...

AI Technical Summary

Problems solved by technology

[0002] For cabinet-type air conditioners such as round cabinets, the air outlet will be set relatively long, which will easily cause the temperature difference at the air outlet to increase. Especially when the evaporator is a single row, it is difficult to ensure uniform temperature at the air outlet. The temperature of the upper air outlet is 45°C, while the temperature of the lowermost air outlet is 35°C, which makes the human body less comfortable

[0003] In the related technology, the large temperature difference is generally avoided by adjusting the refrigerant branch of the evaporator to be very uniform, but there are still some defects. Inhomogeneous; for another example, in the refrigeration system, if the refrigerant leaks, or the evaporator is welded with a slight blockage, etc., the refrigerant flow rate of each refrigerant branch will be inconsistent, which will cause refrigerant deviation during heating. Then there is the phenomenon that the temperature of the air outlet is not uniform
