Present air-conditioning system commonly used mainly is to adopt surface cooler that cool-down dehumidification is carried out in air-supply, and then the heat air-supply is to satisfy the requirement of wind pushing temperature, this processing method exists energy loss, so air-supply has proposed the requirement of hot wet independent process with energy efficient to air-conditioning.In the prior art, is application number 200510029140.? name is called the utility model patent of " heat pump driven energy storage type solution dehumidifying air-conditioning system ", adopted a kind of heat pump driven energy storage type solution dehumidifying air-conditioning system, its cold water end of this system links to each other with room conditioning is terminal, the hot water end links to each other with solution regenerator or cooling tower, on the hot-water line between solution regenerator, cooling tower and the heat pump reversal valve is set, unnecessary heat mode with chemical energy in liquid storage is irritated is stored, realize the wet independent control of heat of air-conditioning system.This utility model system complex mainly is applicable to large-scale central air conditioner system.

The utility model content

Technical problem to be solved in the utility model provides the wet air-conditioning unit of handling respectively of a kind of heat, to solve the problem of the existing energy loss of air-conditioning system commonly used.

The technical scheme that technical problem to be solved in the utility model adopted is: the wet air-conditioning unit of handling respectively of a kind of heat comprises cooling cycle system and solution regeneration system; Cooling cycle system comprises compressor, successively:

Condenser, expansion valve, first evaporimeter, second evaporimeter of series connection, and be connected four-way change-over valve between compressor, condenser and second evaporimeter; Solution regeneration system comprises concentrated solution container, solution pump, first spray equipment of series connection successively, weak solution collection container, second spray equipment, solution pump be connected with the concentrated solution container and be connected between the solution pump and first spray equipment, the solution heat exchanger between weak solution collection container and second spray equipment; Place the first evaporimeter front end air-conditioning ventilating, place the regeneration blower fan of second spray equipment top; It is characterized in that described first spray equipment is arranged on the top of second evaporimeter, the weak solution collection container places the below of second evaporimeter, and second spray equipment is arranged on the top of condenser, and the concentrated solution container places the below of condenser.

Air-supply cools through first evaporimeter earlier in the utility model technology, utilize dense dehumidification solution wherein that dehumidification treatments is carried out in air-supply during then through second evaporimeter, the absorption heat of dehumidification process is taken away by the cold-producing medium evaporation heat absorption of second evaporimeter of flowing through, and sends into each air-conditioned room subsequently through the air-supply that cools.The flow through dense dehumidification solution of the hot regeneration of outside absorption condensation of condenser of weak solution after the dehumidifying, thus a circulation of dehumidification solution formed.Realized the hot wet purpose of handling respectively like this.

Compare with the air-conditioning unit of routine, the wet air-conditioning unit of handling respectively of this novel heat has following advantage: 1, do not dehumidify owing to not needing that apparatus dew point is carried out in air-supply, thereby can improve the evaporating temperature of kind of refrigeration cycle and save operation energy consumption.2,, utilize the condensation heat dehumidification solution of regenerating because its heat that has utilized the evaporation process heat absorption dehumidification process in the kind of refrigeration cycle to produce dexterously.3, the evaporimeter that has dense dehumidification solution with the elder generation's process of blowing, and then the scheme that the general evaporimeter of process cools is compared, the utility model adopts the temperature that reduces air-supply earlier then in the humidity that reduces air-supply, can prevent from not reach under the temperature condition with higher characteristics that dehumidifying requires like this.4, compact conformation is simple, and can realize heating circulation winter, is applicable to the small central air conditioning system, has remarkable economic efficiency.

The specific embodiment

Below in conjunction with accompanying drawing the utility model is further described.

As shown in Figure 1, the wet air-conditioning unit of handling respectively of a kind of heat comprises cooling cycle system and solution regeneration system; Cooling cycle system comprises compressor 1, Chuan Lian condenser 3, expansion valve 5, first evaporimeter 8, second evaporimeter 9 successively, and be connected four-way change-over valve 2 between compressor 1, condenser 3 and second evaporimeter 9; Solution regeneration system comprises concentrated solution container 6, solution pump 11, first spray equipment 12 of series connection successively, weak solution collection container 7, second spray equipment 13, and be connected between the solution pump 11 and first spray equipment 12, the solution heat exchanger 10 between weak solution collection container 7 and second spray equipment 13; Place the air-conditioning ventilating 15 of first evaporimeter, 8 front ends, place the regeneration blower fan 14 of second spray equipment, 13 tops; First spray equipment 12 is arranged on the top of second evaporimeter 9, and weak solution collection container 7 places the below of second evaporimeter 9, and second spray equipment 13 is arranged on the top of condenser 3, and concentrated solution container 6 places the below of condenser 3;

Summer, process of refrigerastion was as follows: cool through first evaporimeter 8 earlier, utilize the dense dehumidification solution under 12 sprays of first spray equipment that dehumidification treatments is carried out in air-supply during then through second evaporimeter 9, the absorption heat of dehumidification process is taken away by the cold-producing medium evaporation heat absorption of second evaporimeter 9 of flowing through, and sends into each air-conditioned room subsequently through the air-supply that cools.

Dense dehumidification solution is owing to the moisture that absorbs in the air-supply becomes weak solution, converge in weak solution collection container 7, heat up through solution heat exchanger 10 and dense dehumidification solution heat exchange then, heat up after the outside that second spray equipment 13 sprays at condenser, the dense dehumidification solution of the hot regeneration of absorption condensation, the surrounding air that the steam of this process evaporation is sent into by regeneration blower fan 14 is taken away, dense dehumidification solution converges in concentrated solution container 6, send into solution heat exchanger 10 through solution pump 6, carry out the heat exchange cooling with weak solution, enter first spray equipment 12 after the cooling.So, form a cyclic process of dehumidifying liquid.

Winter, cold-producing medium was crossed four-way change-over valve 2 reverse circulation at the refrigeration pipe back warp when heating, and first and second evaporimeters become second and first condenser respectively, and condenser becomes evaporimeter.The weak solution collection container becomes the concentrated solution container, and the concentrated solution container becomes the weak solution collection container.Dense dehumidification solution is through second spray equipment, 13 sprays, from the surrounding air that blower fan 14 is sent into, absorb moisture and become rare dehumidification solution, be recycled to first spray equipment 12 through solution pump 11 and solution heat exchanger 10 then, contact the air-supply of moisture transmission being given air-conditioned room with air-conditioning air-supply spray, rare dehumidification solution becomes dense dehumidification solution, constitutes the reverse circulation of dehumidification solution.The process of air-conditioning air-supply absorption moisture is strengthened the absorption of air-supply to moisture by the heat heating that first condenser discharges, and the air-supply behind the absorption moisture is further heated by the condensation heat of second condenser, thereby realizes the purpose of winter to air-conditioning air-supply warming and humidifying
