Problems solved by technology

[0015] First of all, there are limitations in solving the discomfort that indoor people have and providing better comfort to indoor people by only applying PMV and PPD
[0016] Secondly, if the air-conditioning system cannot properly sense the sensitive indoor environment, then the people in the room can easily live in an uncomfortable environment

Embodiment Construction

[0034] Reference will be made in detail to the preferred embodiments of the invention, examples of which are illustrated in the accompanying drawings. Wherever possible, the same reference numbers will be used throughout the drawings to refer to the same or like parts.

[0035] Firstly, the air conditioning system of the present invention measures the current indoor PMV through human and environmental thermal environment parameters, namely air temperature, humidity, air velocity, average radiant temperature, amount of clothing and activity.

[0036] To this end, the air conditioning system of the present invention includes six sensing devices capable of measuring six thermal environment parameters.

[0037] For example, a room temperature can be measured using a temperature sensor, and an average radiation temperature can be calculated by using the room temperature detected by the temperature sensor.

[0038] Also, the relative humidity in the room can be detected by using th...

Abstract

Method for controlling an air conditioning system including the steps of measuring a Predicted Mean Vote (PMV) according to thermal environmental parameters of a room, performing a first air conditioning mode if the PMV falls outside of a preset allowable range, for controlling an air flow speed and a room temperature, and performing a second air conditioning mode S70 if the PMV falls within the allowable range, for controlling ventilation and air cleaning operation, whereby improving the IAQ (Indoor Air Quality) further by enhancing the PPIS by performing air conditioning so that the PMV reaches to an optimum range, and then, by generating active materials (oxygen / terpene).

Description

[0001] This application claims the benefit of Korean Application No. P2005-0012308 filed on February 15, 2005, which is hereby incorporated by reference as if fully set forth herein. technical field [0002] The present invention relates to an air conditioner, and more particularly to a method for controlling an air conditioning system to improve IAQ (indoor air quality). Background technique [0003] These days, people spend about 80% of their day in indoor spaces, such as homes, offices, and underground spaces. For people who spend most of their time indoors, a comfortable indoor environment can improve their productivity and is very important to maintain their health. [0004] Especially as people's living standards become higher, people's requirements for comfortable interior space become higher. [0005] Usually, as time passes, the carbon dioxide content of the air in the closed room increases due to the breathing of the people in the room, and the heat load of the of...
