Problems solved by technology

However, there is no suitable energy-saving solution for public places where people come and go, or where high or low temperatures are deliberately set. If the power is turned off forcibly, it will be at the expense of the comfort of the human body. Controlling the switch of the air conditioner by sensing whether there are people in the room may not necessarily achieve the purpose of energy saving. On the contrary, the power consumption may increase due to the frequent start of the compressor.

Embodiment 1

[0035]The purpose of the present invention is to add an adjustable intelligent energy-saving control switch to air-conditioning equipment (including unitary household air-conditioning equipment and multi-connected commercial air-conditioning equipment), so that the air-conditioner can work according to the set temperature conditions during the working period, and avoid waste of resources. Situation happens. The invention designs a clock circuit and a delay circuit, and performs enable control on the output driving signal according to the set operation time period. The energy-saving switch is equipped with a temperature sensor and a humidity sensor to collect indoor ambient temperature and humidity parameters, design a temperature control circuit and a humidity control circuit, and convert the physical quantities of temperature and humidity into electrical parameters. Design a microprocessor circuit to receive temperature and humidity signals. Compile the control program, carr...

Embodiment 2

[0050] For the occasion of using multi-connected commercial air conditioners, generally one outdoor unit is connected to multiple indoor units, and each indoor unit is equipped with a refrigerant flow control valve (or electronic expansion valve). Therefore, the switch relay of the energy-saving controller cannot control the compression The one-on-off mode of the machine can achieve the purpose of energy-saving control. In this case, by adjusting the structure of the original temperature sensor of the indoor unit, the energy-saving controller can realize the switch control of the flow control valve by affecting the temperature signal input parameter value of the original controller, so as to achieve The purpose of making the air conditioner run at a certain temperature condition for a set period of time.

[0051] The difference between this embodiment and Embodiment 1 is that the second switch relay 62, the cooling high-precision resistor 81 and the heating high-precision resi...

Embodiment 3

[0054] In order to realize the generalization of products, the intelligent energy-saving controller for air-conditioning equipment of the present invention can be applied to unitary household air conditioners and multi-connected commercial air-conditioning systems at the same time, and the first switch relay is reserved on the energy-saving controller and the second switch relay, the output ports of the microprocessor are respectively connected to the first switch relay and the second switch relay, in cooling mode, the control signal of the microprocessor is output to the first switch relay, and at the same time, the second switch relay is normally open. When in the heating mode, the control signal output by the microprocessor is output to the second switch relay, and at the same time, the first switch relay is normally open. When used on a household air conditioner, the first switch relay and the second switch relay are connected in parallel, and then connected in series to t...

Abstract

An intelligent energy-conservation controller of an air-conditioner comprises an air-conditioner and an independent energy-conservation controller, wherein the air-conditioner is provided with a control circuit system; the independent energy-conservation controller comprises a microprocessor, a temperature detector, a parameter setting device, a storage chip, a clock chip and a first switch relay. The temperature detector is installed on an indoor unit of the air-conditioner; an input end of the microprocessor is connected with the temperature detector, the clock chip and the storage chip; anoutput end of the microprocessor is connected with the first switch relay, which is installed on a driving signal line of a compressor of the air-conditioner or connected with a refrigerating high-accuracy resistor and a temperature sensor of the indoor unit of the air-conditioner. The invention aims at reducing energy waste by controlling the working time and temperature range of the air-conditioner, avoiding unreasonable use of the air-conditioner during non-working time,and avoiding excessive resource waste caused by people, furthermore, the intelligent energy-conservation controller can also meet the demand of human body on the degree of comfort while energy is saved.

Description

technical field [0001] The invention relates to the technical field of air conditioner control, in particular to an intelligent energy-saving controller and control method for air-conditioning equipment with an intelligent energy-saving function. Background technique [0002] At present, air conditioners are installed in hotel rooms, classrooms, office spaces, entertainment venues, conference venues and other places. How to reduce power consumption, reduce air conditioning usage costs, improve air conditioner energy-saving control technology, promote energy-saving awareness in our country, and save energy consumption and other issues become more prominent. Relevant surveys show that the air conditioner is not turned off after people leave the room; it is very common for the air conditioner to be too low in office spaces, conference venues, etc., causing a lot of power waste, and it is very necessary to effectively control the power waste caused. Although the state has promu...
