BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an ammonia absorption cycle, and more particularly, to an ammonia absorption cycle aneerator capable of increasing a heat transfer contact area between a refrigerant vapor and a liquor to increase the ammonia concentration of the refrigerant vapor and downsize it.

The ammonia absorption cycle is composed of a regenerator 1, an absorber 2, a condenser 3 and an evaporator 4, as shown in FIG. 1, and the general operating principle is as follows.

In the regenerator 1, a process of separating ammonia as a refrigerant is performed. When the heat of the burner 8 is applied, ammonia refrigerant having a low boiling point is extracted from a solution having a high ammonia concentration (hereinafter referred to as a strong solution) (Hereinafter referred to as " weak solution "). This solution passes through the regenerator heat exchanger (5) before being sent to the absorber (2), and takes part in the regeneration process. This process reduces the amount of heat required for the regeneration process. Since the refrigerant vapor generated in the regenerator 1 contains a considerable amount of water, the refrigerant firstly comes into direct contact with the river solution falling from the upper portion of the regenerator through the annular riser 100, and when the purity of the refrigerant becomes high, Increase the concentration further and send the condenser to (3). The refrigerant vapor is condensed in the condenser 3 to be a liquid refrigerant. At this time, cooling water is used to condense the heat and to condense it.

On the other hand, the liquid refrigerant sent from the condenser is evaporated again in the evaporator 4 to generate the refrigerant vapor. At this time, the liquid refrigerant is evaporated. The required heat amount is obtained from the indoor cold water Supply. And the cold water, which has lost its calories, is sent back to the indoor unit after the temperature drops again, so that it performs the cooling. The evaporated refrigerant vapor is introduced into the absorber 2 via the refrigerant heat exchanger 11 and absorbed into the weak solvent which forms a liquid film from the upper portion of the absorber. This absorber is composed of two parts, a water-cooled absorber 9 and a solution-cooled absorber 10, and the water-cooled absorber discharges absorption heat generated as it is absorbed in the solution by the cooling water to the outside air, Heat exchange with the onion solution increases the temperature of the river solution flowing into the regenerator.

Then, the solution of the steel absorbed in the absorber is sent to the rectifier 7 by the solution pump 12. Further, the refrigerant heat exchanger (11) performs heat exchange between the liquid refrigerant from the condenser and the refrigerant vapor from the evaporator, so that the liquid refrigerant is brought close to the evaporating temperature in the evaporator, and the temperature of the refrigerant vapor is raised It makes the phenomenon smooth. It also evaporates a small amount of refrigerant that does not evaporate in the evaporator.

2 shows the construction of such an ammonia absorption type cycle anaeraser, which is generally located between a regenerator heat exchanger 5 and a rectifier 7, the structure of which is shown in FIG. As shown in FIG. 3, the baffle plates 120 are arranged in a zigzag manner, so that a flow path of the refrigerant vapor 101 is formed from the lower portion of the steel solution 103 and the lower portion. The steel solution 103 whose temperature is raised by the external chemical solution in the solution cooling absorber 10 flows into the upper end portion 103 of the anaeraser 100 of the regenerator and flows directly to the ammonia refrigerant vapor 101 rising from the lower portion The ammonia refrigerant vapor 102 having a higher concentration is subjected to contact heat exchange to the rectifier 7 and the risen solution 104 having the increased temperature flows into the lower end portion of the regenerator 1.

However, in the case of this conventional annularizer, since the steel solution falling from the upper part forms the flow path only by the bezel, the contact time in which the steel solution and the refrigerant vapor can make contact is short and the flow of the solution formed from the upper part to the lower part is uneven Therefore, the concentration of the refrigerant vapor at the inlet of the rectifier is lower than the concentration of the refrigerant vapor at the inlet of the rectifier. This reduces the concentration purity of the refrigerant vapor flowing through the rectifier 7 and adversely affects the entire system.

SUMMARY OF THE INVENTION The present invention has been made in order to solve the problems of the related art, and it is an object of the present invention to provide an ammonia absorbing cycle of an ammonia absorption cycle which can be miniaturized by increasing the contact area and time of heat transfer between the refrigerant vapor and the steel solution, The purpose of the riser is to provide.

In order to accomplish the above object, the present invention provides an ammonia absorption cycle aneerator comprising an anode and an anode, wherein the anode and the anode are connected to each other through a heat exchanger, A plurality of bezel plates arranged in a jig jig along the height of the baffle plate, and coils for forming a flow path of the strong solution disposed between the baffle plates.

Hereinafter, an ammonia absorption cycle anolyzer of the present invention will be described in detail with reference to the accompanying drawings.

The ammonia absorption cycle anaeraser 200 of the present invention comprises an ammonia refrigerant vapor inlet 201 into which the ammonia refrigerant vapor flows from the regenerator 1 into a cylindrical shell 210 as shown in Figures 4 and 5, A refrigerant vapor outlet 202 through which the introduced refrigerant vapor flows out, a steel solution inlet pipe 203 through which the steel solution flows from the absorber 10, and a steel solution outlet 204 through which the introduced steel solution flows out Is installed.

A bipple 220 is disposed in the shell 210 along the height of the shell in a zigzag shape. A bent portion 223 for blocking the flow of the strong solution is formed at the end of the bipple 220 And a flow passage hole 221 is formed in the baffle 220. [ Coils 230 forming a flow path of the strong solution are arranged in a line between the respective baffles 220 in the direction of the flow path hole 221.

Hereinafter, the action of the anaerosis of the ammonia absorption cycle of the present invention will be described.

The ammonia refrigerant vapor produced in the regenerator 1 flows into the annular riser 200 through the refrigerant vapor inlet 210 and is directed upward along the flow path formed by the baffle 220, And the heat exchanged steel solution flows into the upper portion of the annular riser through the steel solution inlet pipe 203.

At this time, the inflow multi-layered solution on the upper part of the annularizer flows along the flow path hole 221 of the bezel 220 along the surface of the coil 230 mounted on the bezel plate and performs heat and mass transfer with the refrigerant vapor rising from the lower part . The steel solution past the passage hole of the bezel is prevented from falling down by the bent portion 223 of the bezel.

The ammonia refrigerant vapor exchanged with the steel solution and having a higher concentration is sent to the rectifier 7 through the refrigerant vapor outlet 202 and the steel solution whose temperature is increased by the heat exchange with the refrigerant vapor is discharged through the steel solution outlet 204 And is sent to the lower end of the player 1.

At this time, since the steel solution flows along the surface of the coil 230, the heat transfer contact area with the refrigerant vapor increases and the accumulation time also increases.

Therefore, the ammonia concentration of the refrigerant vapor discharged from the annularizer 200 can be increased and the height of the annular riser can be reduced.

As described above, according to the present invention, a coil for forming a steel solution flow path is provided in a baffle plate to increase the contact area and time of heat transfer between the refrigerant vapor and the steel solution, thereby reducing the size of the refrigerant vapor. The concentration can be increased.
