Problems solved by technology

However, there are some obvious disadvantages in these detection methods, such as: ① Additional hardware facilities and circuits are required, which increases the overall cost of the air conditioner
②The installation is difficult, and corresponding devices need to be installed on each door and window of the air-conditioned room. When there are many doors and windows, not only the installation is time-consuming, but also a waste of resources
③Whether it is infrared or ultrasonic, when there is a foreign object blocking between the transmitting device and the receiving device, there will be wrong feedback, which will inevitably bring a bad user experience to the user
④Long-term use of ultrasonic ranging may be detrimental to human health

Embodiment Construction

[0034] With the popularization and development of wireless networks such as WI-FI, most air conditioners have been equipped with wireless communication modules such as WI-FI modules, and the WI-FI modules of most air conditioners are only used for communication and basic data conversion. , did not make full use of its own functions such as WI-FI. For a wireless network, the RSSI (Received Signal Strength Indicator) at the receiving end is an important indicator for judging the link quality. However, the air conditioners in the prior art basically do not effectively use this indicator.

[0035] In order to solve the problem of energy waste caused by the continuous high-load operation of air-conditioning equipment when the doors and windows are open, the present invention realizes that the RSSI value of the WI-FI module at the air-conditioning end can be used to analyze the opening and closing of the doors and windows of the air-conditioned room, and then the According to the RS...

Abstract

The invention discloses an energy-saving control system of air conditioning equipment. The air conditioning equipment is installed in a first space. The energy-saving control system comprises a wireless signal transmitting device, a wireless signal receiving device and a control device. One of the wireless signal transmitting device and the wireless signal receiving device is arranged in the first space, and the other one of the wireless signal transmitting device and the wireless signal receiving device is arranged in a second space. A door / window is arranged between the second space and the first space. The wireless signal receiving device is used for communicating with the wireless signal transmitting device. The control device is connected with the wireless signal receiving device and the air conditioning equipment, and used for reading the RSSI value of the wireless signal receiving device and judging the opened / closed state of the door / window so as to control operation of the air conditioning equipment. By the adoption of the energy-saving control system of the air conditioning equipment, the opened / closed state of the door / window of the space where the air conditioning equipment is located can be judged so that corresponding control measures can be taken, and the purpose of saving energy is achieved. The invention further discloses a control method of the energy-saving control system and the air conditioning equipment.

Description

technical field [0001] The invention relates to the technical field of air conditioning, in particular to an energy-saving control system and control method for air conditioning equipment. The invention also relates to an air conditioning system. Background technique [0002] Air conditioners are usually used in relatively closed spaces to provide a comfortable environment for the closed spaces. If the space where the air conditioner is located is not closed, for example, it is connected to other spaces, the load of the air conditioner will be significantly increased, and the energy consumption of the air conditioner will be significantly increased. People often forget to close the doors and windows when using the air conditioner, so that the room where the air conditioner is located is connected with other spaces through the doors and windows, and the air conditioner cannot recognize the opening and closing status of the doors and windows, and continuous operation will ine...
