Energy saving control device for multi-split central air conditioner and control method thereof

Abstract

The invention provides an energy saving control device for a multi-split central air conditioner and a control method thereof. The mechanism for setting the energy saving temperature of a multi-split central air conditioner is realized by locking monitoring software and a communication module; thus, the device is convenient to operate, flexible to manage and not limited by the condition of a manual operator. The device comprises a computer, the communication module and the manual operator; and data transmission is realized through a communication network. The computer comprises an energy saving set module for an air conditioner, which can send out an energy saving set command to the communication module. The communication module comprises a data transmission part, a comparison part and a compulsive modification part, wherein the data transmission part of the communication module transfers communication data between an air-conditioning unit and the computer; the comparison part automatically compares the set temperature on the manual operator of the air conditioner with the set value of the energy saving temperature, which is issued by the computer, so as to determine whether the air-conditioning unit operates at the set energy saving temperature or not; if the discrepancy occurs, the compulsive modification part compulsively uses the set parameter on the manual operator as an energy saving parameter.

Description

technical field [0001] The invention belongs to the field of central air-conditioning automatic control, and in particular relates to a multi-connected central air-conditioning energy-saving control device and a control method thereof. Background technique [0002] With the severe global energy shortage and people's increasing awareness of environmental protection, the Chinese government has explicitly advocated a number of energy-saving measures for air conditioners that consume a lot of energy. The most notable one is the set temperature of the air conditioner. not lower than 27℃. In response to this, many air-conditioning manufacturers have added the function of setting the temperature lock to the hand-held communicator of the multi-connected air conditioner, so as to restrict the air-conditioning end user from setting the temperature at will and achieve the purpose of saving energy. However, this method has also brought many new question: [0003] 1) The operation is c...

AI Technical Summary

Problems solved by technology

[0003] 1) The operation is cumbersome and the management is inflexible. It is necessary to set up each handheld terminal one by one. For projects with many handheld terminals and different energy-saving requirements, the burden on the administrator is very heavy;

[0004] 2) Energy saving can only be achieved by completely relying on the handheld operator. If some handheld operators have no temperature energy-saving function, the energy-saving setting lock cannot be realized;

[0005] 3) In case of a sudden power failure of the handheld terminal, the energy-saving setting may need to be reset, which also increases the burden of management work
