Central air-conditioning system and control method thereof

Abstract

The invention discloses a central air conditioning system and a control method thereof. The central air conditioning system comprises an outdoor unit, an indoor unit, a wire controller, a centralized controller, a cloud server, a user terminal and a Fahrenheit degree conversion module. The Fahrenheit conversion module is used for acquiring currently transmitted centigrade temperature data from the interior of the system and converting the currently transmitted centigrade temperature data into first Fahrenheit temperature data by adopting a Fahrenheit temperature standard conversion formula, the first Fahrenheit temperature data is calculated according to roundness to obtain target Fahrenheit temperature data, and the target Fahrenheit temperature data is sent to the wire controller and / or the user terminal, so that the wire controller and the user terminal are displayed synchronously, but in the system, no matter how a user switches and always transmits the Fahrenheit temperature data, a temperature transmission framework of the current system is not changed; and product switching or transition can be rapidly achieved, table look-up is not needed, errors are not prone to occurring, and the problems that when it is ensured that Celsius degree display and Fahrenheit degree display are synchronous through a table look-up method in an existing system, errors are prone to occurring, and expansion and transplantation are not easy are solved.

Description

technical field [0001] The invention relates to the technical field of air conditioners, in particular to a central air conditioning system and a control method thereof. Background technique [0002] Most of the current central air-conditioning systems transmit temperature values ​​in degrees Celsius. When the product is used in overseas regions, users have the need to use Fahrenheit temperature for control or display, so the conversion between Celsius and Fahrenheit needs to be considered. [0003] The conversion formula between Celsius C and Fahrenheit F is C=(F-32) 1.8, it can be seen that there is a linear but non-integer correspondence between Celsius and Fahrenheit. [0004] Such as figure 1 The central air-conditioning system shown includes outdoor units, indoor units, wire controllers, centralized controllers, cloud servers, and user terminals. When the user needs to operate the temperature in Fahrenheit, the system needs to switch the temperature of the wire cont...

AI Technical Summary

Problems solved by technology

[0006] In order to solve the existing problem of error-prone, difficult to expand and transplant existing in the central air-conditioning system through the table look-up method to ensure the synchronization of Celsius and Fahrenheit switching, the temperature transmission framework of the current central air-conditioning system is not changed, and the system is converted to Fahrenheit through the Fahrenheit conversion module. The internally transmitted Celsius temperature is converted into the target Fahrenheit temperature data and sent to the wire controller and user terminal for display, while the system always works in the Celsius mode, which has the least impact on the overall system, and can quickly realize the switching or switching of overseas products to Fahrenheit. Transition from domestic products to overseas products
