Abstract

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.

Description

technical field [0001] The invention relates to a marine energy-saving air conditioner utilizing exhaust heat energy, and belongs to the technical field of air conditioners. Background technique [0002] During the voyage of modern ships, diesel main engines are the main energy-consuming equipment for ships, and their energy consumption accounts for 70%-90% of the total energy consumption of the entire ship. However, the thermal efficiency of the host is low, only about 50%. Other heat is discharged to the atmosphere or marine environment through exhaust, cooling and heat dissipation, which not only wastes energy but also pollutes the environment. [0003] The exhaust temperature of the main engine is 260°C to 400°C, and the outlet temperature of the cylinder jacket cooling water is 70°C to 90°C. A large amount of waste heat can be used for refrigeration on board. At present, the ship's air-conditioning device is mainly based on vapor compression refrigeration. Air treatme...
