Embodiment approach 1

[0045] figure 1 It is the floor plan of the building to which the air-conditioning apparatus of Embodiment 1 of this invention was applied. figure 2 It is a figure which shows the connection structure of the air-conditioning apparatus concerning Embodiment 1 of this invention. exist figure 1 , figure 2 And in the figures mentioned later, what attached|subjected the same code|symbol is the same or corresponds to it, and it is common throughout the whole specification. Furthermore, the form of the component shown in the whole specification is an illustration only, and is not limited to these descriptions.

[0046] like figure 1 As shown, the air-conditioning apparatus includes a plurality (here, two) of refrigerant systems 1 and 2 as air-conditioning systems. The refrigerant systems 1 and 2 each include an outdoor unit 10 and an indoor unit 20 connected to the outdoor unit 10 by a refrigerant pipe 30 . In addition, here, four indoor units 20 are provided for each of the...

Embodiment approach 2

[0135] In Embodiment 1, the case where the system integration operation is applied to the air-conditioning apparatuses of two systems was described, but in Embodiment 2, the case where the system is applied to the air-conditioning apparatuses of three systems is described. In addition, the modifications applied to the same parts as in the first embodiment are also similarly applied to the second embodiment.

[0136] Figure 16 It is the floor plan of the building to which the air-conditioning apparatus of Embodiment 2 of this invention was applied.

[0137] The air-conditioning apparatus according to Embodiment 2 includes a refrigerant system 1 , a refrigerant system 2 , and a refrigerant system 3 , and air-conditions the same room 100 using the three refrigerant systems. Each of the refrigerant systems 1 , 2 , and 3 includes an outdoor unit 10 and a plurality of indoor units 20 connected to the outdoor unit 10 through refrigerant piping 30 . The air conditioner is further e...

Abstract

Equipped with: refrigerant systems 1, 2 having an outdoor unit 10 and an indoor unit 20 for air-conditioning the same room 100; and a circulator 40 for uniformizing the temperature distribution in the room and determining the operating refrigerant systems 1, 2 For each load, when it is judged that the expected operating efficiency is improved based on the load judgment result, the operation of the refrigerant system judged to be low load is stopped, and the operation is integrated into the refrigerant system judged to be high load. Consolidation operation, and the blown air blown from the indoor unit 20 of the refrigerant system judged to be high load is sent to the air conditioning section of the refrigerant system judged to be low load through the circulator 40 .

Description

technical field [0001] The present invention relates to air conditioning devices. Background technique [0002] Conventionally, an air conditioner has been proposed that includes: a plurality of indoor units arranged in one air-conditioning target area; a plurality of outdoor units in which the indoor units are divided into a plurality of systems and provided for each system, and The system control unit operates according to the request from the indoor unit of the system; the system control unit controls the corresponding outdoor unit according to the request from the indoor unit belonging to each system; and the overall control unit controls a part of the system according to the operation load of each system. Pause (for example, refer to Patent Document 1). [0003] In this air-conditioning apparatus, by stopping the system operating at a low load, the air-conditioning load of each system can be increased, and the efficiency of the air-conditioning apparatus can be improve...
