An energy-saving boat air conditioner using
tail gas
heat energy comprises a first air cooler, a solution cooler, a solution tank, a solution pump, an air pipeline, a second air cooler, a cabin, a coil
pipe cooler, a
lithium bromide absorption type refrigerating unit, a dehumidifier, a
waste heat heater and a regenerator. The solution cooler, the solution tank, the solution pump, the dehumidifier, the
waste heat heater and the regenerator are sequentially connected through pipelines, the
lithium bromide absorption type refrigerating unit is connected with the dehumidifier, the second air cooler and the coil
pipe cooler through pipelines, the coil
pipe cooler is arranged in the cabin, and the air pipeline is sequentially connected with the first air cooler, the second air cooler and the dehumidifier and then enters the cabin. A LiCl solution is used for absorbing
moisture in air for dehumidifying, the LiCl solution is diluted and regenerated by means of hot water at the temperature
ranging from 70 DEG C to 90 DEG C, high-temperature cold water is made through the
waste heat absorbing type refrigerating unit to process
thermal load of the cabin, and accordingly independent
processing of
humidity load and the
thermal load is achieved, and
humidity and temperature of the cabin can be independently controlled.
