The present invention provides an air filtering system for use in a building and an HVAC system, wherein the air filtering system includes: an outside-air inlet; a first filtering stage at the downstream of the outside-air inlet; a second filtering stage at the downstream of the first filtering stage; a collection module for collecting outside-air quality information; and a control module in communication with the collection module, wherein the control module adjusts an operation state of the first filtering stage and/or the second filtering stage based on the air quality information collected by the collection module. The system of the present invention has the advantages of energy saving, low maintenance cost, etc.

Air filter system and HVAC system

A method for improving the effectiveness of a building air circulation system having motorized blower and a contamination filter. The method including predicting a cost of operation of the system over an operational duration based on at least electricity consumption of the motor (), and an operational cost to operate the filter (), predicting a cost of maintenance of the system over the operational duration based on at least one of, a condition of the filter (), a cost of a filter (), a cost of labor to clean or replace the filter (), and an effectiveness of the filter () over the operational duration, and balancing the cost of operation of the circulation system versus the cost of maintenance of the circulation system over the duration to recommend at least one of a filter use/bypass schedule, a filter maintenance schedule, and a fresh air input schedule satisfying an operation objective and an operational constraint.

Condition based energy smart air circulation system

A building air conditioning control system for controlling the comfort degree of air in at least one floor area of the building, and includes: a first head counting module to acquire first head count change data of a floor area according to a weight change of a cabin of an elevator when passing the corresponding floor area; a second head counting module to acquire second head count change data of the floor area according to data acquired by an image sensor mounted in the corresponding floor area; and an air conditioning control module to correct head count change data based on the first head count change data and the second head count change data, and control the comfort degree of air in the floor area based on the corrected head count change data. The building air conditioning control system and control method provide accurate control and good user experiences.
