This invention discloses a household absorption air conditioner / generator, belonging to the field of integrated refrigeration, air conditioning, and power generation technology. The device eliminates the traditional compressor, installing a 3-6KW direct-drive permanent magnet micro-generator in the original compressor location, equipped with a planetary or turbine gearbox. The core heat exchange component uses a graphite titanium plate heat exchanger, and the outer casing is made of titanium. Calcium chloride-ammonia water is used as the working fluid pair, with the fluids in the condenser and absorber in a gas-liquid two-phase state. An external liquid pump and solution pump are provided, and the plate condenser has a vacuum port; an external micro-vacuum pump draws a vacuum to reduce the vaporization temperature. The device achieves switching between cooling, heating, and standalone power generation modes via a circuit board, with the generator autonomously powered by a condenser fan. Its heat transfer coefficient reaches 6000-7000W / (m²・K), water consumption is only 5%-10% of traditional equipment, and energy efficiency is 60%-90%. Cooling and heating switching is achieved by reversing the external circulation pump. The product is suitable for areas without electricity, islands, deserts and other scenarios. It can be used for both military and civilian purposes, and can meet the dual needs of household air conditioning and daily electricity use. It is energy-saving, environmentally friendly and has a broad market prospect.
