Indoor space temperature distribution measurement and automatic air inlet and exhaust control method and device

Abstract

The invention discloses an indoor space temperature distribution measurement and automatic air inlet and exhaust control method and device. More than one temperature sensor is arranged in an indoor space; a temperature to frequency conversion technology is adopted for converting each detected temperature value into periodic signals of different frequencies, so that a high signal to noise ratio can be obtained under long-distance transmission; a digital frequency detection technology is adopted for a temperature measuring module, so that the temperature value of a certain configuration point can be obtained once the frequency of a receiving signal is detected; and a digital direct-current variable-frequency technology is adopted for a speed-regulating control module, so that the rotating speed and direction of each adjustable-speed inlet and exhaust fan can be adjusted segmentally. Due to the adoption of the method and the device, the air temperature can be distributed at a specific target, and economic and stable effects are achieved.

Description

technical field [0001] The present invention relates to an indoor space temperature distribution measurement and automatic air intake and exhaust control method and device, in particular to a method and device that detects the temperature distribution in an indoor space in a wired manner and separately controls the speed and speed of each adjustable speed intake and exhaust fan. Direction, by being able to energy-efficiently renew the indoor air and control the temperature distribution in the room to meet the needs of specific applications. Background technique [0002] At present, the temperature sensor of the traditional automatic air-conditioning equipment is configured together with the equipment, which can only maintain the temperature near the air-conditioning equipment within the set range, while the temperature in other indoor areas or where people are usually different from the set value temperature. In order to maintain the indoor temperature distribution to meet ...

AI Technical Summary

Problems solved by technology

However, due to the movement of people in the room or the change of the position of the placed objects, the temperature distribution will be affected, and even the air conditioning equipment and its pipelines need to be frequently moved.

[0003] And the traditional automatic air-conditioning equipment either lacks a ventilation system, or does partial ventilation in the air-conditioning equipment, so the air in the indoor space of the traditional automatic air-conditioning is always full of various waste gases and poisonous gases, so that it is harmful to human health; at the same time , the traditional refrigerant-type air-conditioning equipment will cause holes in the atmosphere, indirectly cause global warming, and consume a lot of power, and do not meet the needs of energy saving and carbon reduction

[0004] In addition, in order to read the temperature values ​​at different locations in the indoor space of the existing air-conditioning equipment, it is necessary to employ one or more assistants to help the hand-held thermometer to move the measurement, which is quite labor-intensive and time-consuming; or one or more expensive standard remote control interfaces are used If the wireless transmission design is adopted, it may be interfered by noise, resulting in measurement distortion or creating more electromagnetic noise harmful to the human body in the environment; most of the existing air intake and exhaust fan equipment do not have standard wired Control interface, if you buy an intake and exhaust fan with a standard wired control interface, you will spend a lot of money
