Central air conditioner controller, as well as prepaid and multi-mode control system and method for central air conditioner

Abstract

The invention relates to a central air conditioner controller with a prepaid function and a multi-mode control function. The central air conditioner controller has the functions of temperature sensing, time control, prepaid management and remote communication, and comprises a data storage module, an electric energy measurement module, a temperature sensing module, a display module, a keystroke module, a wireless communication module and a central processor. The central air conditioner controller controls a blower and a valve to control the use of the central air conditioner, that is, the central air conditioner controller allows to open the blower and the valve under the conditions that the remaining cost is greater than zero within the accessible time and temperature; when the remaining cost is equal to zero, or the temperature does not satisfy the serviceable range, or the time is not available, the central air conditioner controller closes the blower and the valve. The control management function of the central air conditioner controller avoids energy waste caused by the random use of the central air conditioner, and monitoring and management on the use of the central air conditioner are enhanced simultaneously.

Description

technical field [0001] The invention relates to the field of air-conditioning control, in particular to a central air-conditioning controller, a central air-conditioning prepaid and multi-control system and method. Background technique [0002] Traditional central air-conditioning costs are usually calculated according to the prior agreement, or according to the area, or according to the number of central air-conditioning fans used, etc., which cannot be billed according to specific usage, which will easily lead to asymmetry between usage and charging, resulting in waste of energy efficiency serious. The traditional central air-conditioning controller can only manually set the operating temperature, wind speed gear, and manually turn it on and off, which cannot effectively control the central air-conditioning, resulting in serious energy waste. Contents of the invention [0003] Based on this, it is necessary to provide a central air-conditioning controller that saves ene...
