Roof-top air conditioner

Abstract

The embodiment of the invention provides a roof-top air conditioner, and belongs to the technical field of air conditioners. The roof-top air conditioner comprises a roof-top unit and terminal devices installed in rooms, the terminal devices are connected with the roof-top unit through air pipes, and the roof-top unit comprises a fan used for generating air flow in the air pipes and a controller used for controlling the rotation speed of the fan; the terminal devices in the rooms can receive running instructions input by users and sending the running instructions to the controller, and the controller can adjust the rotation speed of the fan according to the running instructions to enable the size of the generated air flow to adapt to the strength of the air pipes. According to the technical scheme of the embodiment, the using safety and comfortableness of the roof-top air conditioner can be improved.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to a rooftop air conditioner. Background technique [0002] For ducted air-conditioning systems, in order to control the air volume, a common method is to install a manual or electric on-off valve at the end of the air duct, and close the on-off valve when the user does not need to use the air conditioner. [0003] For example, the Chinese utility model patent CN20181935U provides a terminal air supply air volume control device for station air conditioners. The device is equipped with an electric valve at the straight pipe section of the Venturi pipe, and the opening of the electric valve is controlled by the Venturi flow controller, which can realize The control of the air supply volume is not only low in cost, but also relatively more accurate in measurement and control accuracy, which can meet the requirements of different users on the ambient temperature. [0004] The ...

AI Technical Summary

Problems solved by technology

[0006] The roof-mounted air conditioner sends air to each air-conditioned room through the air duct. If an uncontrollable diffuser is used at the end of the air duct, or an end device with an on-off valve is used, the two technical defects mentioned above cannot be overcome.

[0007] In addition, for the existing frequency conversion roof-mounted air conditioners, the roof-top units installed on the roof generally cannot collect real-time feedback on the use information of users in each room, and cannot perform frequency conversion control and load regulation well, and cannot achieve optimal use. effect, the application effect of frequency conversion technology will be greatly reduced

[0008] In addition, for the frequency conversion rooftop air conditioners in commercial applications, there is no control device at the end of use in each air-conditioned room, and each commercial tenant cannot realize individual shutdown. cost, which will greatly limit the application occasions of inverter roof air conditioners
