Example Embodiment

[0030] [Embodiment 1]

[0031] (Structure of air conditioning device 101)

[0032] figure 1 It is a figure which shows an example of the air conditioning apparatus 101 in Embodiment 1 of this invention. Such as figure 1 As shown, the air conditioning apparatus 101 includes an indoor unit 103, an outdoor unit 104, and a control device 130.

[0033] The indoor unit 103 includes an indoor blower 113, an indoor heat exchanger 115, an infrared sensor 110, a piping temperature sensor 111, and an indoor temperature sensor 121. The outdoor unit 104 includes an outdoor blower 114, an outdoor heat exchanger 116, an expansion valve 117, a four-way valve 118, and a compressor 119. The outdoor heat exchanger 116, the expansion valve 117, the four-way valve 118, the compressor 119, and the indoor heat exchanger 115 are connected in a ring shape by the refrigerant pipe 120, thereby constituting the refrigerant circuit 102. A heat pump is formed by circulating the refrigerant in the refrigerant c...

[0090] [Embodiment 2]

[0091] Hereinafter, Embodiment 2 of the present invention will be described. The air-conditioning apparatus of Embodiment 2 includes a control device for controlling the plurality of indoor units 103 for making the indoor temperature of the air-conditioned space R a target temperature. Since the control of the load detection means, temperature detection means, air blowing control means, and wind direction control means of each indoor unit 103 is the same as that of the first embodiment, illustration and description are omitted.

[0092] Picture 11 It is a diagram showing an example of a control system in the second embodiment. The indoor units 103A, 103B, and 103C are connected to the centralized control device 230 through communication devices 203, 204, and 205, respectively. The indoor units 103A, 103B, and 103C can be controlled from the centralized control device 230. The connection between the indoor units 103A, 103B, 103C and the communication devi...

Abstract

An air conditioning device (101) includes a refrigerant circuit (102), a piping temperature sensor (111), an indoor blower (113), an air conditioning load detection section (125), and a control device(130). The piping temperature sensor (111) detects a condensation temperature (CT). The indoor blower (113) regulates the amount of air flow delivered to an indoor heat exchanger (115). The air conditioning load detection section (125) detects an air conditioning load. The control device (130) has an operation mode having a first mode and a second mode different from the first mode, and the control device (130) controls the amount of air flow delivered by the indoor blower (113). In the second mode, the control device (130) operates the indoor blower (113) so that, as the condensation temperature changes, the amount of air flow will change between a first air flow amount and a second air flow amount which is greater than the first air flow amount. If, during the first mode, an air conditioning load detected by the air conditioning load detection section (125) decreases to a level below a first threshold, the control device (130) changes the operation mode from the first mode to the second mode.

Description

technical field [0001] The invention relates to an air conditioning device, in particular to the air supply control of an indoor unit. Background technique [0002] During the heating operation of the air conditioner, since hot air moves upward due to its light specific gravity, the temperature of the floor tends to drop easily. Therefore, in the heating operation of the conventional air-conditioning apparatus, comfort is improved by sending hot air to the feet using a fan. In order to further improve comfort during heating, an air conditioner as described in, for example, JP 2010-60250 A (Patent Document 1) has been proposed. [0003] The air conditioner described in Japanese Patent Application Laid-Open No. 2010-60250 controls the direction and volume of air supply at that time according to the position of people in the room and the user's intention, and provides a comfortable air-conditioned space more efficiently.
