Air conditioner for automatically adjusting air quality and adjusting method thereof

Abstract

The invention discloses an air conditioner for automatically adjusting the air quality and an adjusting method thereof. The air conditioner comprises an indoor air quality sensor, an outdoor air quality sensor, an indoor humidity sensor, an outdoor humidity sensor, an indoor dust sensor, an outdoor dust sensor, an indoor temperature sensor, an outdoor temperature sensor and a ventilating device, wherein the ventilating device is at least provided with a PG motor. In addition, the air conditioner also comprises an air quality control module, a humidity control module, a temperature control module and a ventilating control module, wherein the air quality control module is used for comparing indoor air quality data with outdoor air quality data and for generating and outputting a ventilating signal or a non-ventilating signal; the humidity control module is used for comparing indoor humidity data with outdoor humidity data and for generating and outputting a ventilating signal or a non-ventilating signal; the temperature control module is used for comparing indoor temperature data with outdoor temperature data and for generating and outputting a ventilating signal or a non-ventilating signal; and the ventilating control module is used for starting the PG motor to ventilate under the conditions of simultaneously meeting all the ventilating signals and for turning the PG motor off under the condition of meeting part of the ventilating signals. The invention automatically dehumidifies, humidifies and controls the ventilating amount and has a scientific air quality improving method.

Description

technical field [0001] The invention belongs to the field of automatic control of air conditioners, and in particular relates to the coordinated control technology of temperature, humidity and air quality of an air conditioner. Background technique [0002] With the expansion of the scope of human activities and the rapid development of industrial modernization, the quality of ambient air has attracted people's attention. The existing air conditioner adjustment technology cannot intelligently analyze and automatically adjust the air quality function. Although there are air quality detection devices that can detect some harmful gases in the air and realize detection control and alarm or air change functions, they cannot achieve the functions of air conditioners. The air conditioner with air quality detection and air change function in the prior art also has the following defects: 1. The gas detection area is not wide, and the detection is limited to indoor applications, and t...

Problems solved by technology

The existing air conditioner adjustment technology cannot intelligently analyze and automatically adjust the air quality function. Although there are air quality detection devices that can detect some harmful gases in the air and realize detection control and alarm or air change functions, they cannot achieve the functions of air conditioners. The air conditioner with air quality detection and air change function in the prior art also has the following defects: 1. The gas detection area is not wide, and the detection is limited to indoor applications, and the quality of outdoor gas is not accurate. detection, just a simple air change job, often sucking outside air into the room that is worse than the indoor air

2. Lack of comparative analysis of indoor and outdoor humidity

Moreover, if the air conditioner is in the dehumidification process, if the outdoor humidity is much higher than the indoor humidity, changing the air will obviously affect the dehumidification effect. Similarly, if the indoor is dry and needs to be humidified, if the outdoor humidity is lower than the indoor humidity, changing the air will affect the humidification Effect, in this case, dehumidification, humidification and wind exchange will waste power resources

3. Lack of analysis and processing of indoor and outdoor temperature and set temperature to carry out air change operation. Due to the accompanying energy loss often occurs during the air change process, when the difference between the indoor temperature and the set temperature is large, whether it is Heating or cooling, if the air exchange volume is not properly controlled, the indoor temperature is difficult to reach the ideal set value, for example: cooling, the indoor temperature is 33°C, and the set temperature is 25°C, the temperature difference between the two is large, obviously changing the air at this time It will make it difficult to reach the set value indoors, because the current air exchange technology will inevitably cause the indoor cooling capacity to be brought outdoors to varying degrees, which will also waste power resources

4. There is a lack of control of different air exchange volumes based on air quality, humidity, and temperature conditions. For example, under indoor cooling, the air quality is high, the difference between the indoor temperature setting value is small, and the difference between the indoor humidity setting value is large. In this case, a single Uncontrolled and uncontrollable air volume technology does not meet the needs of humanization

In short, the current technology does not have a comprehensive data analysis of the difference between indoor and outdoor air quality, humidity, and temperature, and cannot effectively control the dehumidification mode and air exchange volume of the air conditioner. Therefore, it is easy to cause waste of resources and air quality. Did not get the improvement it deserves, lack of humanized automatic operation
