A central air-conditioning billing monitoring device, system and method based on wireless wifi

Abstract

The invention relates to a wifi-based charging monitoring device, system and method for a central air conditioner. The wifi-based charging monitoring device is in wireless connection with a plurality of fan coils of the central air conditioner. Each fan coil communicates with an air conditioner main unit of the central air conditioner. The charging monitoring device comprises electric two-way valves, cloud temperature controllers, a plurality of wireless access points, a switch and a central control unit. The electric two-way valves and the cloud temperature controllers are the same as the fan coils in number and are arranged on the fan coils in a one-to-one correspondence mode, and the cloud temperature controllers are in one-to-one correspondence with the electric two-way valves and the fan coils through wifi signals transmitted by one wireless access point. All the wireless access points are connected with the switch. The switch is connected with the central control unit. According to the wifi-based charging monitoring device, system and method, through wifi, connection between the cloud temperature controllers and the fan coils as well as the electric two-way valves is achieved, the advantages of fast data responses, the movable temperature controllers, easy construction and easy maintenance can be achieved, and the defects of low communication efficiency, existing of delaying, high construction cost and difficult maintenance of an existing mode are overcome.

Description

technical field [0001] The present invention relates to the technical field of air conditioners, in particular to a central air conditioner billing monitoring device, system and method based on wireless wifi. Background technique [0002] With the rapid development of society and the continuous improvement of human living standards, central air-conditioning has been more and more widely used in commercial, hotel, office buildings, government agencies, residential quarters, high-end apartments, schools, In hospitals and other fields, while central air-conditioning solves the problem of comfort, its energy consumption has also attracted more and more attention. The energy consumption of building air-conditioning accounts for 15-20% of the energy consumption of the whole society. [0003] At present, the billing monitoring of central air-conditioning has the defects of low communication efficiency, delay, difficult return control, high construction cost, and difficult maintenan...

AI Technical Summary

Problems solved by technology

[0003] At present, the billing monitoring of central air-conditioning has the defects of low communication efficiency, delay, difficult return control, high construction cost, and difficult maintenance, and most of them generally adopt the method of charging by area or installing a heat meter

Although the method of charging by area is simple, convenient and low in cost, it cannot mobilize the behavior of users to save energy, and users have no awareness and behavior of energy saving, resulting in a large waste of energy; the method of charging by installing heat meters requires accurate measurement of each terminal device, and every Each terminal needs to install a flow meter and two thermometers, which not only requires a large investment, high cost, and difficult maintenance, but also has a short service life of the heat meter; The higher the rate, the existing central air-conditioning billing system cannot realize online payment, and users cannot remotely monitor and control their own air-conditioning terminal equipment through smart phones, which brings inconvenience to users; at the same time, the country is vigorously promoting smart communities, smart Urban construction, which also objectively requires that the central air-conditioning billing system cannot be an information island isolated from the outside world
