Air-conditioning and electric power generating system and control method for the same

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...

Problems solved by technology

[0004] The conventional structures described above generally generate electricity with high efficiency during air conditioning, use the generated electricity to suppress the electricity consumption from an external commercial power supply, and use the power consumption less than the specified electricity consumption. In the adjusted state, the gas engine is stopped and no power generation is performed
