Problems solved by technology

On the other hand, if the rotational speed is low, the operating efficiency will be low, for example, if the operating speed is below 30% of the rated rotational speed, the efficiency will be significantly reduced
Therefore, in the structure in which a plurality of air conditioners equipped with inverter compressors are installed as shown in the above-mentioned Patent Document 4, if the operating load is distributed to each air conditioner to be approximately even, the rotation speed of each air conditioner will decrease at the same time. The danger of reduced operating efficiency

Embodiment approach 1

[0084] Such as figure 1 As shown, the air conditioning system 100 of the first embodiment includes an electric power system 1, a warm water system 2, and a system controller 3 that monitors and controls the operating status of each device included in the air conditioning system 100.

[0085] The electric power system 1 includes an industrial power supply system 11 supplied from an electric power company and a plurality of external power generation devices connected to the industrial power supply system 11 in the system. The external power generation device of this embodiment is composed of a photovoltaic power generation device 12 as a DC power generation device, a GHP generator 13 (hereinafter referred to as a generator 13), and a battery 18. The power system 1 is configured to have a PCS (power conditioner. It corresponds to the output circuit of the present invention.) 14 as a device for converting DC power to AC power and superimposing it on wiring. The photovoltaic power gen...

Embodiment approach 2

[0136] Next, Embodiment 2 of the present invention will be described. In the first embodiment, the power consumed by the load is detected, the amount of power is compared with the power generated by the generator and the photovoltaic power generation device, and it is determined whether the generated power is charged to the battery or supplied to the load, so that the rechargeable battery can be used efficiently Of electricity. In contrast, in the second embodiment, by predicting in advance the amount of power consumed by the load and the power generated by the generator and the photovoltaic power generation device, the power of the battery can be used efficiently.

[0137] In the air conditioning system of Embodiment 2, since the overall configuration of the air conditioning system of Embodiment 1 is the same, the same reference numerals are used for the same configuration, and detailed descriptions are omitted.

[0138] The system controller 3 of the second embodiment detects th...

Embodiment approach 3

[0167] Next, use Figure 7 ~ Figure 10 The specific configuration of the air conditioners 22a' and 22b' of the third embodiment will be described. The same reference numerals are added to the same structures as the above-mentioned Embodiments 1 and 2, and detailed descriptions are omitted.

[0168] Such as Figure 7 As shown, the air-conditioning system 100 of the third embodiment includes an electric power system 1, a warm water system 2, and a system controller (corresponding to the “control unit” of the present invention) that monitors and controls the operating status of each device included in the air-conditioning system 100 )3.

[0169] The generator 13 is mounted on the outdoor unit 21 of the air conditioner 20. The outdoor unit 21 of the air conditioner 20 includes a gas engine 24 using gas as fuel, a gas pipe 26a for supplying gas to the gas engine 24, and a gas supply port 26 connected to the gas pipe 26a. The gas supply port 26 passes through the gas pipe 26a. The gas ...

Abstract

The invention provides an air conditioning system. The air conditioning system (100) comprises a charging part (19) controlling the charging of a storage battery (18), a DC generating device (12), a detector (32) detecting the power supply to a load (22), and a control part (3). When the detected power is below the total value of the output of a generator (13) and the DC generating device (12), the control part (3) enables a circuit which introduces the output of the generator (13) and the DC generating device (12) into the charging part (19), and enables an output circuit which converts the DC power of the storage battery (18) into AC power and superimposes the AC power on a routing; and when the detected power is above the total value of the output of the generator (13) and the DC generating device (12), the control part (3) enables an output circuit which converts the DC power from the generator (13) into AC power and superimposes the AC power on a routing, and enables an output circuit which converts the DC power from the DC generating device (12) into AC power and superimposes the AC power on a routing.

Description

Technical field [0001] The present invention relates to an air conditioning system having a refrigeration cycle using a compressor, a condenser, a pressure reducing device, and an evaporator, and a generator driven by a power source for driving the compressor. Background technique [0002] In the prior art, it is known that in a system that supplies electric power to a battery to loads such as home appliances during a period of high power consumption, the amount of electric power required for the next day is predicted, and the battery is determined based on the predicted amount of electric power. The structure is charged in advance (for example, refer to Patent Document 1 below). [0003] In large-scale factories that consume a lot of energy, there is a gas heat pump (GHP) that drives a compressor by a gas engine. The remaining energy of the gas engine is used to generate electricity. At the same time, energy saving is improved by using the exhaust heat of the gas engine. Effectiv...
