The specific embodiment

Below in conjunction with drawings and Examples, the utility model is further described.

Ship Waste Heat solution dehumidification energy-saving type air conditioner, comprise the first air cooler 1, solution cooler 2, solution tank 3, solution pump 4, air duct 5, the second air cooler 6, cabin 7, coiled pipe cooler 8, lithium-bromide absorption-type refrigerating machine group 9, dehumidifier 10, heater heated by waste heat 11 and regenerator 12, described solution cooler 2, solution tank 3, solution pump 4, dehumidifier 10, heater heated by waste heat 11, between regenerator 12, by pipeline, connect successively, lithium-bromide absorption-type refrigerating machine group 9 is by pipeline and dehumidifier 10, the second air cooler 6, coiled pipe cooler 8 is connected, coiled pipe cooler 8 is arranged in cabin 7, air duct 5 connects the first air cooler 1 successively, the second air cooler 6, after dehumidifier 10, enter in cabin 7, send into compared with dry air.

Between described solution cooler 2, solution tank 3, solution pump 4, dehumidifier 10, heater heated by waste heat 11, regenerator 12, by pipeline, realize successively closed connection, realize waste heat dehumidifying.

Described the first air cooler 1, solution cooler 2 are all connected with seawater, for cooling.

Solution system is divided into two loops: dehumidifying loop and regenerative loop, two loops cross at solution tank 3 places.The function that solution tank 3 is separated solution make the to dehumidify solution pump 4 of loop can extract the higher solution of concentration by solution pump 4A from solution tank 3, pass into the liquid distributor at dehumidifier 10 tops, by the nozzle on liquid distributor, sprayed, after absorbing airborne steam, solution concentration reduces, cooling coil in dehumidifier 10 can be taken away dehumidification process liberated heat simultaneously, and weak solution flows back to solution tank 3 by Action of Gravity Field.The solution pump 4B of regenerative loop extracts the solution that concentration is lower from solution heat exchanger, and passing into heater heated by waste heat 11 will heat in weak solution, and the thermal source in heater heated by waste heat 11 can be from main engine jacket cooling water, 80-90 ℃ of exit temperature.In regenerator 12, outdoor new wind directly contacts with heated solution the exchange of carrying out heat and quality, and air is directly discharged after being heated humidification.The concentrated solution of regeneration, flows back to solution tank 3 by Action of Gravity Field, simultaneously can be cooling by brine cooler, complete regenerative process, and continual absorption airborne steam like this goes round and begins again.

The exhaust-heat absorption formula refrigeration unit that native system is selected is lithium-bromide absorption-type refrigerating machine 9, in running, can utilize boat diesel engine cylinder cooling water (85 ℃ of left and right of outlet temperature) as the heat source of generator.

Operation principle of the present utility model: new wind (38 ℃) is by 32 ℃ of the first air cooler 1(ocean temperatures) cooling, temperature is down to 33 ℃, and this is a wet cooling procedure such as grade.

New wind is through internally-cooled solution dehumidifying device 10, and airborne steam is absorbed, and water capacity reduces, and liberated heat is pulled away, i.e. the process of isothermal dehumidifying, and temperature maintains 33 ℃.
