Abstract
Provided is an indoor environment control system including: an indoor environment device which includes a ventilator, an air purifier, and a kitchen hood; a thermal comfort device which includes a heater, an air cooler, a humidifier, and a controller; and a control device which, when the indoor temperature and humidity are within a preset comfort range, controls an operation of at least one of the indoor environment device and the thermal comfort device on the basis of indoor and outdoor fine dust concentrations.
Claims10
An indoor environment control system, the system comprising:
- an indoor environment device including a ventilator, an air purifier, and a kitchen hood;
- a thermal comfort device including a heater, an air cooler, a humidifier, and a controller;
- and
- a control device including a sensor module and configured to control an operation of at least one of the indoor environment device and the thermal comfort device based on an indoor fine dust concentration and an outdoor fine dust concentration, when indoor temperature and humidity are within a preset comfort range,
- wherein the control device is further configured to:
- measure, by the sensor module, the indoor temperature, the humidity, the indoor fine dust concentration, and the outdoor fine dust concentration;
- compare the indoor fine dust concentration and the outdoor fine dust concentration to control an operation of at least one of the ventilator, the air purifier, and the kitchen hood, when the indoor temperature and the humidity are within the preset comfort range;
- calculate a concentration difference by comparing the indoor fine dust concentration and the outdoor fine dust concentration;
- and
- control the operation of at least one of the ventilator, the air purifier, and the kitchen hood according to the concentration difference, and
- wherein when the concentration difference is within a third reference concentration difference range and the indoor fine dust concentration is lower than the outdoor fine dust concentration, the control device operates the air purifier according to the third reference concentration difference range to be turned on.

An operation method of an indoor environment control system, comprising:
- measuring indoor temperature and humidity, an indoor fine dust concentration, and an outdoor fine dust concentration;
- determining whether the indoor temperature and the humidity are within a preset comfort range;
- calculating a concentration difference by comparing the indoor fine dust concentration and the outdoor fine dust concentration when the indoor temperature and the humidity are within the preset comfort range;
- and
- controlling an operation of at least one of a ventilator, an air purifier, and a kitchen hood included in an indoor environment device based on the concentration difference,
- wherein, in the controlling the operation, when the concentration difference is within a third reference concentration difference range and the indoor fine dust concentration is lower than the outdoor fine dust concentration, the air purifier operates to be turned on according to the third reference concentration difference range.
