[0063] (1) Overall structure

[0064] figure 1 The shown air conditioning system 1 is a system for supplying conditioned air to an air-conditioning target space SA. In the air-conditioning target space SA, there are rooms RA1, RA2, etc. in the building BL. The rooms RA1 , RA2 are separated by a partition wall 78 . Here, the case where the air-conditioning target space SA is two rooms RA1 and RA2 will be described, but the air-conditioning system 1 can cope with various sizes, various shapes, and various numbers of rooms. The air-conditioning target space SA to which the air-conditioning system 1 supplies conditioned air is preferably surrounded by walls (front and back, up and down, left and right) like the rooms RA1 and RA2. In addition, the air-conditioning target space SA is not limited to the rooms RA1 and RA2, and may be, for example, a corridor, stairs, and an entrance. The air-conditioning target space SA may be, for example, one space such as a lobby, or may be a p...

[0235] (6) Overall structure

[0236] The aspect in which the main controller 40 controls the plurality of actuators based on a plurality of instructions related to the supply air volumes of the plurality of fan units 30 is not limited to the aspect of the first embodiment. The air conditioning system 1 in which the main controller 40 controls a plurality of actuators based on a plurality of instructions related to the supply air volume of the plurality of fan units 30 may also be configured as in the second embodiment. In the air conditioning system 1 of the second embodiment, the plurality of sub-controllers, that is, the plurality of blower controllers 34 receives a plurality of instructions from the main controller 40 . In the air conditioning system 1 of the second embodiment, the plurality of fan controllers 34 respectively control at least one of the plurality of actuators according to at least one of the plurality of instructions.

[0237] Specifically, the air condit...

[0244] In the above-mentioned second embodiment, the case where the fan motor 33 functions as an actuator for changing the amount of supplied air has been described. However, the actuator for changing the amount of supplied air in the second embodiment is not limited to the fan motor 33 . For example, as multiple executors, it is also possible to use Figure 5 The drive motor 39 for the damper 38 is shown. Figure 5 The blower motor 33 of the blower blower 32 shown may be a motor of the type whose rotation speed can be changed, as in the second embodiment, or a motor whose rotation speed cannot be changed. When the fan motor 33 is of a type whose rotational speed cannot be changed, for example, only the damper 38 changes the amount of air supplied from the fan unit 30 to the outlet unit 70 (air volume). On the other hand, when the fan motor 33 is of a type whose rotation speed can be changed, not only the opening degree of the damper 38 is changed, but also the amount of air...

Abstract

The present invention controls the supply of conditioned air so as to suppress energy consumption on a heat source side by supplying conditioned air using ducts in an air conditioning system. A heat exchanger unit (10) includes a usage-side heat exchanger (11). A plurality of ducts (20) distribute conditioned air that has passed through the usage-side heat exchanger (11) of the heat exchanger unit (10). A plurality of fan units (30) draw in conditioned air from the heat exchanger unit (10) via the plurality of ducts (20) and supply the same to a space (SA) subject to air conditioning. Each of the fan units (30) further includes a fan motor (33), which is an actuator configured so as to be capable of changing individual air supply amounts of the conditioned air. A controller controls the plurality of fan motors (33) so as to respectively control the air supply amounts of the plurality of fan units (30).

Description

technical field [0001] The present disclosure relates to an air conditioning system including a plurality of fan units. Background technique [0002] Among conventional air conditioning systems for air-conditioning the interior of a building, there is an air-conditioning system that supplies conditioned air to a building using ducts, as described in, for example, Patent Document 1 (Japanese Patent Application Laid-Open No. 11-132489 ). multiple locations within. Contents of the invention [0003] The technical problem to be solved by the invention [0004] However, in the air-conditioning system described in Patent Document 1, the content of control of the fan unit is described without considering the energy saving performance on the heat source side. [0005] In such an air conditioning system that uses ducts to supply conditioned air to multiple locations in a building, there is a technical problem of how to control the conditioned air in a manner that suppresses energ...
