Energy management device based on split air conditioner

Abstract

The invention discloses an energy management device based on a split air conditioner. The device comprises a transceiver control module, and a power supply module, an electricity consumption metering module, a communication module, a data storage and real-time clock module, a relay output control circuit, an infrared receiving and dispatching circuit and a temperature measuring circuit which are connected with the transceiver control module, wherein the electricity consumption metering module comprises a voltage and current sampling circuit and an electricity quantity acquisition module; the communication module comprises a Lonworks twisted-pair transceiver, a wireless intelligent transceiver and a power line carrier transceiver; the wireless intelligent transceiver comprises an encoding and decoding unit and a wireless radio frequency module; one end of the encoding and decoding unit is connected with the transceiver control module; the other end of the encoding and decoding unit is connected with the wireless radio frequency module. By applying the energy management device, the communication quality is safe and reliable; the speed is high; the problems of not high energy consumption efficiency and unresoanble energy consumption of an existing split air conditioner are solved.

Description

Technical field [0001] The invention relates to the technical field of energy and energy saving, in particular to an energy management device based on split air conditioners. Background technique [0002] In hot summer and cold winter, the cooling and heating of split air conditioners bring people a comfortable temperature environment. According to statistics from authoritative departments, air-conditioning accounts for more than half of the electricity used in buildings, and split air-conditioning is the “big consumer” of the entire building, especially office buildings. At the same time, in real life and work, the following unreasonable energy use scenarios often occur when using split air conditioners: (1) Premature and unreasonable use of the ambient temperature conditions for summer or winter use; (2) Non-use The standby energy consumption caused by turning off the indoor unit but not cutting off the power supply; (3) The air conditioner temperature is set too low in summer...

AI Technical Summary

Problems solved by technology

At present, there is no product that can solve the standby energy consumption of the split air conditioner at the same time. It can be connected to the Internet to send remote commands to control the switch and replace the remote control to set the temperature of the air conditioner. It can set the temperature threshold of different air conditioners in different seasons to control timely use. , The split air conditioner can be activated according to the temperature setting for cooling or heating (standby / running), it can be turned on and off according to the time period or schedule, and the energy consumption of the split air conditioner can be measured, energy fee settlement and access The energy management system uploads the sub-item data of air-conditioning power consumption to provide a basis for energy-saving management. It has twisted pair or wireless or power line network communication. It is easy to install and only needs to replace the original power supply socket, etc.
