Embodiment Construction

[0025] Embodiments of the present invention are described below with reference to the drawings.

[0026] FIG. 1 is an explanatory diagram of a gas engine-driven air conditioner-power generation system.

[0027] The air conditioning-generating system 1 is configured to include an outdoor unit 2 and a plurality of indoor units 3a to 3c, which are connected by an inter-unit piping 4 composed of a liquid pipe 4a and a gas pipe 4b. The outdoor unit 2 accommodates a gas engine 10 , a generator 11 that generates electricity by the driving force of the gas engine 10 , and a compressor 12 that compresses refrigerant by the driving force of the gas engine 10 .

[0028] The gas engine 10 generates driving power by combusting a mixture of fuel such as gas supplied through the fuel regulating valve 7 and air supplied through the throttle valve 8 .

[0029] The generator 11 has a power generation capability corresponding to the drive capability of the gas engine 10 when the compressor 12 i...

Abstract

The present invention relates to an air conditioner-power generation system and a control method thereof, which are controlled so as to achieve a required NOx emission concentration or NOx emission amount in each operation mode. It comprises: a gas engine (10); an air conditioner having an outdoor heat exchanger, a decompression device, an indoor heat exchanger and a compressor (12) connected to the gas engine (10) through an electromagnetic clutch (14); a generator (11), which is driven by a gas engine (10), and has a power generation capability corresponding to the driving capability of the gas engine (10) when the compressor is separated from the gas engine (10) by an electromagnetic clutch (14); system link Converter (33), it is connected with generator (11) and carries out electric output to commercial system; Exhaust heat exchanger (29), it utilizes the waste heat of gas engine; Outdoor controller (39), as the gas engine (10) The driving mode of driving control, which has: the first control mode as a gas engine control for driving the compressor (12) and the generator (11) and the gas engine control mode as a gas engine for driving the generator (11) The second control mode of the control.

Description

technical field [0001] The present invention relates to an air conditioner-power generation system and a control method for an air conditioner-power generation system, in particular to the ability to provide hot water and other waste heat utilization, and use a gas engine to drive a compressor and a generator to simultaneously perform air conditioning and power generation, or only An air conditioner-power generation system for generating power and a control method for the air conditioner-power generation system. Background technique [0002] In conventional engine-driven air conditioners, a compressor that compresses refrigerant is driven by an engine such as a gas engine to perform an air-conditioning operation. In recent years, a generator is connected to the gas engine, and the power generated by the generator is supplied, for example, to load devices such as a blower for blowing air to an outdoor heat exchanger or a cooling water pump for cooling the engine. Air conditi...
