Description

HIGH TEMPERATURE GENERATOR FOR AN ABSORPTION REFRIGERATOR}

The present invention relates to a high temperature regenerator of an absorption chiller, and more particularly, by installing a filter medium in the form of a mesh mesh to suppress the rise of the solution particles in the high temperature regenerator to prevent the evaporation of the solution particles contained in the vapor, It relates to a high temperature regenerator of an absorption refrigerator that can prevent the deterioration of the freezing capacity.

The air conditioner can be classified into various types according to the refrigerant to be used, and in particular, water is used as the refrigerant as the absorption chiller. In an absorption type refrigerator using water as a refrigerant, lithium bromide is mainly used as an absorbent, and water and lithium bromide solution are heated using steam or high temperature water. Referring to FIG. Brief description of the absorption chiller.

1 is a block diagram showing a general absorption chiller, Figure 2 is an enlarged view showing an absorption tube of the absorption chiller according to the prior art. First, as shown in FIG. 1, when the schematic configuration of the absorption chiller is shown, the high temperature regenerator 2 for heating the rare solution introduced from the high temperature heat exchanger 10 and the liquid refrigerant pipe 32 are provided. The low temperature regenerator 8 having the condenser 20 in which the rare solution introduced from the high temperature regenerator 2 is evaporated and condensed by water vapor, and the condensed water introduced from the condenser 20 through the liquid refrigerant pipe 34 are evaporated. Evaporator 22 and absorber 24 for absorbing water evaporated by the absorbent. The evaporator 22 and the absorber 24 are arranged inside the cell 2. Usually, the liquid refrigerant pipes 32 and 34 use copper pipes or steel pipes for pressure piping, and elbows or the like are used for the curved pipe parts.

The coolant introduced along arrow P passes through absorber 24 and condenser 20 in sequence along pipe 18 and is then discharged along arrow P '. The cold water introduced along arrow Q is It is introduced into the evaporator 22 along the pipe 30 and cooled, and then supplied to the cooling coil along the arrow Q 'to cool the room.

The absorption chiller is provided with three pumps 12, 14 and 16. Among these, the absorption pump 12 serves to extract the diluted solution and send it back to the absorber 24. The refrigerant pump 14 sends the water not evaporated from the evaporator 22 back to the atomizer on the evaporator 22. The regeneration pump 16 serves to send the concentrated absorption solution introduced through the suction pipe 40 to the high temperature regenerator 2 through the low temperature heat exchanger 8 and the high temperature heat exchanger 10.

Here, the absorption solution sent to the high temperature regenerator 2 is supplied with external heat source steam, and the refrigerant is evaporated to become refrigerant vapor, and the non-evaporated absorption solution is returned to the high temperature heat exchanger 10 as a heavy solution. In this series of processes, when the refrigerant vapor is evaporated in the high temperature regenerator 2, the absorbent solution particles are mixed with the refrigerant vapor and condensed on the tube side of the low temperature regenerator 8 through the refrigerant liquid pipe 32, and then the evaporator 22 Flows into. At this time, the pure condensation refrigerant (specific gravity is 1.02 or less) is introduced from the evaporator 22 to improve the freezing capacity, when the solution particles are mixed in the evaporator 22, the pure refrigerant is contaminated to reduce the freezing capacity. In order to prevent mixing of the solution particles, a baffle plate as shown in FIG. 2 is installed in the high temperature regenerator.

2 is a cross-sectional view showing a high temperature regenerator of an absorption type refrigerator, in which the absorbent solution in the high temperature regenerator (2) cell is moved along the direction of the arrow by refrigerant vapor evaporated by steam supplied to the heat source through a pipe (3) from the outside. . In this evaporation process, a plurality of baffle plates 52 are inclined in the vapor box 50 of the high temperature regenerator 2 to prevent the solution particles from being mixed with the refrigerant vapor.

However, since the baffle plate installed in the high temperature regenerator of the conventional absorption chiller does not completely collect the solution particles, the refrigerant vapor is mixed with the solution particles to carry-over to contaminate the refrigerant, resulting in a decrease in the freezing capacity. Will result.

The present invention devised to solve such a problem is to prevent the degradation of the refrigerating capacity by installing a mesh wire mesh type demister to completely trap the solution particles inside the high temperature regenerator to prevent mixing with the refrigerant vapor. It is an object of the present invention to provide a high temperature regenerator of an absorption refrigerator.

An object of the present invention described above is a high temperature regenerator for heating a rare solution introduced from a high temperature heat exchanger through a liquid refrigerant pipe, and a condenser in which a rare solution introduced from a high temperature regenerator through a liquid refrigerant pipe is evaporated into water vapor and condensed. An absorption chiller comprising a built-in low temperature regenerator, an evaporator in which condensed water introduced from the low temperature regenerator through a liquid refrigerant pipe and an absorber for absorbing refrigerant vapor evaporated by an absorbent are provided. It is achieved by the high temperature regenerator of the absorption type refrigerator, characterized in that a filter wire in the form of a mesh is installed in the vapor box into which the refrigerant evaporated from the inlet is introduced.

Hereinafter, a high temperature regenerator of an absorption type refrigerator according to a preferred embodiment of the present invention will be described in detail with reference to the accompanying FIG. 3, and the same components as in the conventional structure described with reference to FIG. 1 are denoted by the same reference numerals.

3 is a cross-sectional view showing the internal structure of the high temperature regenerator according to the present invention.

As illustrated in FIG. 1, a normal absorption cold / hot water machine includes a high temperature regenerator 2 for heating a rare solution introduced from a high temperature heat exchanger 10, and a condenser 20 for condensing steam introduced from the high temperature regenerator 2. Is equipped with a low temperature regenerator (8), an evaporator (22) that exchanges heat with cooling water passing through the pipe (30) while the condensate flowing from the condenser (20) evaporates, and an absorber (which absorbs vapor evaporated by the absorbent) 24) is provided.

In the absorption type cold and hot water heater having such a configuration, a method for removing the solution particles in the refrigerant vapor when the absorption liquid is evaporated by receiving the external heat source steam in the preferred embodiment of the present invention in the steam box 50 of the high temperature regenerator (2) The method of installing the filter body 60 was illustrated.

That is, in the steam box 50 into which the refrigerant evaporated from the inside of the cell of the high temperature regenerator 2 by the steam flows, a filter body 60 in the form of a mesh is provided. Therefore, even when the solution particles are mixed and introduced into the vapor box 50 in the process of evaporating the absorbing solution by the heat source steam supplied through the pipe 3, all of the solution particles are formed by a demister in the form of a mesh wire mesh. Is collected. Accordingly, only the refrigerant vapor passing through the filter body 60 is discharged along the arrow P through the outlet 54 and sent to the evaporator 22.

According to the present invention described above, since the mesh wire mesh filter (DEMISTER) is installed in the high temperature regenerator to completely collect the solution particles and prevent them from being mixed in the refrigerant vapor, the solution particles are the refrigerant during the evaporation of the refrigerant. It can fundamentally prevent incorporation into steam. Therefore, pure condensation refrigerant (specific gravity 1.02 or less) flows into the evaporator, thereby preventing the deterioration of the freezing capacity.
