Problems solved by technology

[0003] In addition, when the difference between the set temperature and the room temperature is large, the indoor fan may continue to rotate at a high speed for a long time.
As a result, the air blown out from the air outlet of the indoor unit continues for a long time with a large air volume, which may cause discomfort to the user such as noise, drafts, shaking of documents, and messy hair.

Embodiment approach 1

[0024] figure 1 It is a system configuration diagram of Embodiment 1 of the present invention. The air conditioner 1 includes an outdoor unit 10 arranged outside the air-conditioned space 100 , and a first indoor unit 20 and a second indoor unit 30 arranged inside the air-conditioned space 100 . That is, a plurality of indoor units are arranged in one air-conditioned space 100 . Each of the first indoor unit 20 and the second indoor unit 30 is an air conditioner capable of multi-connection, and is connected to one outdoor unit 10 . In Embodiment 1, the capacity (kW) of the first indoor unit 20 is higher than that of the second indoor unit 30 . By operating the remote controller 21, the user can select the operation mode of the first indoor unit 20, the volume and direction of the air blown out from the air outlet, and the like. Similarly, the user can select the operation mode of the second indoor unit 30 , the volume and direction of the air blown out from the air outlet, ...

Embodiment approach 2

[0038] Next, Embodiment 2 of the present invention will be described. In Embodiment 2, an indoor unit having the same capability as that of the first indoor unit 20 is used as the second indoor unit 30 . It should be noted that in Embodiment 2, except that the capability of the first indoor unit 20 is the same as that of the second indoor unit 30, the system configuration, refrigerant circuit configuration, control block configuration, and wind speed switching conditions with reference to Figure 1 to Figure 5 Embodiment 1 described is all the same, and therefore description thereof will be omitted.

[0039] In Embodiment 2, when the quietness priority mode is set in the first indoor unit 20 and the second indoor unit 30 , the outdoor unit control mechanism 16 increases the number of people detected by the human sensors 27 and 37 in the air-conditioned space 100 . The wind speed of the indoor fan of the presence of the indoor unit. Such as figure 1 As shown, in the air-con...

Abstract

Multiple indoor units are connected to one outdoor unit in an air conditioner. When the quietness priority mode is set in a plurality of indoor units, each indoor unit is controlled so as not to select a control level corresponding to a predetermined wind speed or higher among a plurality of control levels of wind speed, and the indoor units are controlled to pass through the plurality of indoor units. Each indoor unit is controlled in such a way that the temperature difference between the temperature and the indoor temperature is reduced by the sum of the capabilities of the respective indoor fans.

Description

technical field [0001] The present invention relates to an air conditioner equipped with a function of automatic air volume operation. Background technique [0002] Conventionally, in an air conditioner equipped with an automatic air volume operation function, the rotation speed of the indoor fan of the air conditioner is controlled based on the difference between a set temperature arbitrarily set by a user through a remote controller or the like and the room temperature of the air-conditioned object. Specifically, when the difference between the preset temperature and room temperature is large, the rotation speed of the indoor fan is increased, and when the difference between the preset temperature and room temperature is small, the rotation speed of the indoor fan is decreased. By controlling the rotational speed of the indoor fan in this way, the air volume of the air blown out from the air outlet of the indoor unit is controlled (see Patent Documents 1 to 3). [0003] A...
