An air-conditioning system includes: a controller configured to: extract a lower limit load that occurs at a minimum, in a load that occurs in an air-conditioned space and that changes depending a time period; distribute a proportion at which the extracted lower limit load is to be processed, as a processing proportion stored in a memory; control each of air-conditioning apparatuses that are at a second place and subsequent places in apparatus rankings, such that the lower limit load is processed and distributed, and to control an air-conditioning apparatus that is at a first place in the apparatus rankings, such that a remaining load of the lower limit load and a fluctuating load that occurs over the lower limit load are processed. 1: An air-conditioning system comprising:a plurality of air-conditioning apparatuses configured to condition air in an air-conditioned space;a storage unit configured to store an apparatus rankings created for the plurality of air-conditioning apparatuses in order of a shorter time taken to reach a set temperature, and a processing proportion of a load to be processed by each of the air-conditioning apparatuses that are at a second place and subsequent places in the apparatus rankings; anda controller configured to control operation of the plurality of air-conditioning apparatuses, wherein an extraction unit configured to extract a lower limit load that occurs at a minimum, in a load that occurs in the air-conditioned space and that changes depending a time period,', 'a distribution unit configured to distribute a proportion at which the lower limit load extracted by the extraction unit is to be processed, as the processing proportion stored in the storage unit, and', 'an air-conditioning control unit configured to control each of the air-conditioning apparatuses that are at the second place and subsequent places in the apparatus rankings, such that the lower limit load is processed at the processing proportion distributed by the ...

Air conditioner and controlling method thereof

The present disclosure provides an air conditioner capable of improving user convenience because a ventilation mode in which heat exchange between indoor air and outdoor air is performed and a ventilation mode in which the heat exchange is not performed are selectable by a user and a controlling method of the air conditioner. To this end, the air conditioner includes an indoor introduction air path configured to introduce air into an indoor space and an outdoor discharge air path configured to discharge air to an outdoor space, wherein the outdoor discharge air path includes an air path in which heat exchange is performed with the air introduced into the indoor space, and a by-pass path in which heat exchange is not performed with the air introduced into the indoor space, and the air conditioner further includes a controller configured to control the air discharged to the outdoor space so that the air discharged to the outdoor space flows to one of the air path, in which the heat exchange is performed, and the by-pass path.

Air-conditioning system and controller

The air-conditioning system includes: an opening/closing device opening and closing an openable portion in an opening of a building; an air-conditioning device performing air-conditioning inside the building by consuming energy for operation; a monitoring device monitoring environmental information regarding the inside and outside of the building; and a controller controlling the opening/closing device and the air-conditioning device based on the environmental information from the monitoring device, date and time information representing a current date and time, building information representing a location condition of the building, and draft information determined by parameters including an opening area and an opening shape in the openable portion. The controller opens the openable portion and stops the air-conditioning device when the outside is more favorable in air environment than the inside, and closes the openable portion and starts the air-conditioning device when the inside is more favorable in air environment than the outside.

Systems and methods for controlling operations of a heating and cooling system

Techniques for controlling a heating, ventilation and air conditioning (HVAC) system at a site are disclosed. A disclosed method includes obtaining or calculating a net load at the site and obtaining a temperature of the site during a time period. The method further includes comparing the net load to a threshold load value and comparing the temperature to a lower threshold temperature or an upper threshold temperature. The method also includes determining one or more operation parameter values for the HVAC system based at least in part on the comparison of the net load to the threshold load value and the comparison of the temperature to the lower threshold temperature or the upper threshold temperature, and setting the HVAC system based on the one or more operation parameter values.
