Abstract: An air-conditioning system includes an air-conditioning apparatus, a ventilation apparatus, a detector configured to detect an environment state in an air-conditioning target space and a position and an activity state of a person present in the air-conditioning target space, a storage device configured to store a plurality of control patterns, and a controller configured to calculate, for each of the control patterns, thermal environment distribution information and air age distribution information in the air-conditioning target space by using operation states and the environment state, calculate, for each of the thermal environment distribution information, a local comfort level index from the position and the activity state of the person, and determine, a control pattern to be set to the air-conditioning apparatus and the ventilation apparatus which satisfies a pre-determined standard.

Abstract: An air-conditioning apparatus includes: a housing; a first heat exchanger; a second heat exchanger; a first fan; a second fan; a control valve; and a controller that controls the control valve and the first and second fans. The housing includes a first air outlet and a second air outlet. The controller sets in the air-conditioning target space, a first area associated with the first air outlet and a second area associated with the second area, detects whether a person or persons are present or no person is present in each of the first and second areas, and controls the control valve and the first and second fans such that air conditioning is performed in the first area and an air-blowing operation is performed in the second area, when detecting that the person or persons are present in the first area and no person is present in the second area.

Abstract: An air-conditioning ventilation system includes a ventilation device configured to ventilate an air-conditioned space while controlling a ventilation rate, an air-conditioning apparatus that includes a heat exchanger configured to exchange heat between refrigerant and air and that is configured to operate while controlling an air-conditioning capacity thereof to bring an indoor temperature in the air-conditioned space to a setting temperature, and a controller.

Abstract: An air-conditioning system includes an air-conditioning apparatus including indoor units, temperature detectors each of which detects a temperature of an associated one of zones into which an air-conditioning target space is divided in association with positions of the indoor units, a human detection sensor which detects whether each of the zones is a human presence zone where a person or persons are present or a human absence zone where no person is present, and a controller that causes the indoor unit in the human presence zone to perform cooling/heating operation, thereby causing a temperature detected by the temperature detector in the human presence zone to reach a set temperature. The controller causes the indoor unit in the human absence zone to perform air-sending operation, and determines the volume of air from the indoor unit in the human absence zone based on that in the human presence zone.

Abstract: An air-conditioning system includes an air-conditioning apparatus, a user-detecting unit detecting, for users, an amount of activity and a position, a storage device storing, for each amount of activity, a group including comfort index distributions each corresponding to each of air-conditioning control patterns of the air-conditioning apparatus, and a controller configured to obtain an air-conditioning control pattern that enables a comfort efficiency to be maximum, by specifying the group corresponding to the amount of activity for each of the users, extracting the comfort indexes corresponding to the position of each of the users from the comfort index distributions in the specified group, and, based on the comfort indexes extracted corresponding to the position of each of the users, calculating the comfort efficiency indicating a comprehensive comfort level of the users for each of the air-conditioning control patterns.

Abstract: A control apparatus includes a RAM, a non-volatile storage device, and a computing device. The RAM stores an object file including an unresolved symbol. The non-volatile storage device stores a control program that can be updated. The computing device controls reception of the object file, generates a symbol-resolved object file by resolving the unresolved symbol, and updates the control program by using the symbol-resolved object file. The non-volatile storage device stores a symbol table in which only a function and a global variable that are accessed by the computing device executing a program described in the object file and that are allowed to be referred to during a process of updating the control program are defined. The computing device resolves the unresolved symbol by using the symbol table.

Abstract: A control apparatus comprises a RAM storing an object file comprising an unresolved symbol; a non-volatile storage device storing a first control program incapable of being updated and a second control program capable of being updated; and a computing device controlling reception of the object file, generating a symbol-resolved object file by resolving the unresolved symbol, and controlling a control target device by using the first control program and the second control program. The computing device updates the second control program by using the symbol-resolved object file.
