Description

Solar absorption type air conditioner and its control method {Apparatus and control method for absorption type heating and cooling machine driven by solar energy}

The present invention relates to a device and a control method for improving the performance of the absorption type air conditioner using solar heat.

As the society develops and the standard of living improves, the demand for a more comfortable living environment and the work environment is increasing, and accordingly, the spread of the air conditioning facilities that can artificially control the indoor heat environment and the cleanliness of the air is rapidly increasing. Large buildings for commercial purposes, as well as small and medium-sized buildings, schools, government offices, and general residential spaces are in process.

As a result, the demand for a refrigerator, which is one of the heat source devices constituting the air conditioning system, is rapidly increasing, and its usage is also rapidly increasing due to the recent climate change. As a result, there is a growing interest in energy-saving and eco-friendly refrigerators and heaters from an economic perspective of energy saving and an environmental perspective of environmental protection.

Almost all refrigeration and air conditioning technologies currently sold and developed for home use have been based on efficient electric compressors. However, most electric compressors use electricity as a power source, which consumes enormous energy during the summertime. Therefore, the national policy recommends the use of cold storage and absorption chillers in order to facilitate the continuous supply of energy.

Figure 2 relates to the structure of an absorption type air conditioner driven by an external heat source according to the prior art.

The basic components of the absorption air conditioner are composed of five types: absorber 260, evaporator 250, condenser 240, low temperature regenerator 230, and high temperature regenerator 220, and their positions vary depending on the design method. For example, the absorber 260 and the evaporator 250 are positioned at the lower side of the condenser 240 and the low temperature regenerator 230, and the high temperature regenerator 220 is next to the condenser 240 and the low temperature regenerator 230. In addition, the secondary components include a high temperature heat exchanger 280, a low temperature heat exchanger 270, a refrigerant pump, a solution pump, a burner, and the like, and these are generally located for stable operation and easy maintenance.

As these absorption air conditioners are widely used, many studies have been conducted to improve the performance of the absorption air conditioners.

Representative examples include high efficiency high temperature / low temperature solution heat exchanger, refrigerant drain heat exchanger, solution cooling inhaler, exhaust gas / solution heat exchanger, air preheater, and two stage evaporator / absorber.

However, many studies are concentrated on the absorber 260, the evaporator 250, the heat exchanger (270, 280), etc., the research on the efficiency of the condenser 240 is insufficient.

Meanwhile, in the operation of the absorption chiller, the absorption liquid may crystallize during operation or when the heat source is stopped. In order to prevent crystallization, there are a melting method in which a high-temperature condensation refrigerant is put in a crystal part and a heating method for heating a crystal part. However, this method also takes a long time from stop to a steady state. An additional device is required to insert the material, and there are inconveniences such as heating the crystal part manually and heating it.

Although an operation method of controlling a gas burner by selecting a smaller valve opening degree by comparing a valve opening degree obtained by a PID operation having the outlet temperature of the cold water as a variable, a gas burner is disclosed. The improvement of the overall system is not taken into account because the focus is on the efficiency of the system. That is, the efficiency of the absorption type air conditioner, in addition to controlling the amount of heat of the heat source, there is a method of controlling the refrigerant, a method of adjusting the absorbing liquid, but there is no consideration therein.

On the other hand, in the general structure in which the absorber and the evaporator are installed in the same fuselage, the steel sheet or the stainless steel sheet is used to prevent the absorber's absorbent liquid from passing through the evaporator and contaminating the refrigerant with the absorbent liquid and degrading the capacity of the freezer. 하고 ”type bent wing is installed, but in order to install it, it is difficult to manufacture because it needs to pile up several layers of“ 형 ”type wings and screw it to the frame. In this case, the absorbing liquid dispersed in the support plate may be lowered into the refrigerant, and the cooling capacity may be lowered or the cooling capacity may be lost.

1 is an overall system configuration utilized in the air-conditioning using a solar heat absorption air-conditioner according to the present invention.

Referring to FIG. 1, solar heat is collected by the solar heat collecting plate or the solar collector 110 to pass the heat exchanger 170 or directly store the energy of the sun in the heat storage tank 120. Then, the energy stored in the heat storage tank is supplied to the absorption air conditioner 150 by a heat exchanger or directly supplies heat to a high temperature regenerator (not shown) of the absorption air conditioner 150. Afterwards, an apparatus for regenerating low temperature (eg, a refrigerator, an air conditioner) or a device requiring a high temperature (eg, a heater, a heater, etc.) is driven by an operation of the absorption air conditioner.

3 is an overall configuration diagram of a solar heat absorption type air conditioner according to the present invention.

The present invention is an absorption type air conditioner (300) that uses solar heat as a heat source. Specifically, a heat collector 301 for collecting solar heat and a heat storage tank 302 for storing water heated by heat collected from the heat collecting plate, and the heat storage tank 302. Solar absorption type air conditioner (300) including an absorption air conditioner for regenerating cold water using the stored hot water, from the evaporator (350) and the evaporator (350) to obtain cold water at low temperature by latent heat by evaporating the condensed and decompressed refrigerant liquid. Absorber 360 for absorbing the refrigerant vapor into the absorbent solution, a high temperature regenerator 320 for heating the absorbent liquid by heat of a heat source to separate the refrigerant and a low concentration absorbent liquid, the refrigerant vapor supplied from the high temperature regenerator 320 A low temperature regenerator 330 for heating the absorption liquid to separate the refrigerant by evaporation, a condenser 340 for cooling the refrigerant vapor with cooling water or air to condense it, The heat exchanger 380 that exchanges heat between the absorbent liquid transferred to the high temperature regenerator 320 and the absorbent liquid of the high temperature regenerator 320 and the absorbent liquid transferred to the low temperature regenerator 330 and the absorbent liquid of the low temperature regenerator 330 are heat-exchanged. A low temperature heat exchanger 370 is included.

Apparatus and method for storing solar heat in a heat storage tank, the operation principle of the absorption air-conditioner and the specific operation principle of each component are well-known techniques and detailed description thereof will be omitted.

The present invention provides an apparatus for recycling the excess heat of the absorbent liquid of the absorber 360 by discarding the excess heat of the absorbent liquid of the absorber 360 to the heat exchanger with the high temperature steam regenerated by the cold regenerator 330 in the condenser 340. .

The absorber 360 absorbs the refrigerant vapor regenerated in the evaporator 350 into the absorbent liquid in the absorber 360 to maintain a constant pressure in the evaporator 350, and the heat regenerated in the absorption process is absorbed by the absorber 360. The absorbing liquid, which is discarded by the cooling water flowing into the pipe and absorbs the refrigerant vapor and whose concentration is thinned, is transferred to the condenser 340 through the refrigerant pump 361. The condenser 340 is further provided with a condensation heat exchanger 390 to exchange heat with the high temperature steam of the low temperature regenerator 330.

The absorbent liquid heat exchanged in the condensation heat exchanger 390 is sent to the low temperature heat exchanger 370.

In the low temperature heat exchanger 370, the high temperature absorbent liquid coming from the low temperature regenerator 330 and the low temperature absorbent liquid heat exchanged in the condenser 340 are heat-exchanged.

In a conventional absorption air conditioner, the absorber of the absorber is directly sent to the low temperature heat exchanger, so the temperature difference between the absorber of the high temperature absorber and the absorber from the low temperature regenerator decreases so that the heat exchange efficiency decreases. According to the present invention, the absorber of the absorber is heat exchanged in the condenser. Since it passes through the relatively low temperature absorbent liquid is transferred to the low temperature heat exchanger, the heat exchange effect in the low temperature heat exchanger is increased.

7 is an eliminator structure according to the present invention.

In the eliminator according to the present invention, the eliminator is formed of a plate-shaped metal material 710 at a portion separating the absorber and the evaporator, and a predetermined number of perforated holes are formed on the surface of the metal plate, and the punched position The metal plate 720 in the bend in the direction of the absorber so that its end is directed to the lower part of the absorber.

Typically the evaporator and absorber are integrally formed and the hot water vapor of the evaporator is absorbed in the absorber. At this time, since the absorber is dispersed in the absorber, in the case of the conventional "∧" plate-shaped eliminator, there is a possibility that the absorbed liquid dispersed through the plate is introduced into the refrigerant of the evaporator.

The eliminator according to the present invention of FIG. 7 has such a disadvantage that the hot water vapor of the evaporator is well introduced into the absorber, but the absorbent liquid dispersed in the absorber does not flow into the evaporator. In addition, the eliminator is made of a single plate to be detachably coupled at the time of installation, so that the installation and absorption liquid blocking effect is higher than that of combining the "∧" shaped plate in the conventional individual eliminator separately.

On the other hand, when the absorption type air conditioner is restarted after the operation stops, there may be crystallized absorbent liquid in each circulation line and the removal of the absorbed air conditioner and returning to normal operation depends on how quickly the crystallized absorbent liquid is removed.

The present invention proposes a structure for achieving this in a simple and efficient manner.

Specifically, the absorbent liquid inside the absorber was directly sent to the high temperature regenerator to form a heat exchanger and then circulated to the absorber via the low temperature heat exchanger. As a result, the crystals can be quickly resolved in the part containing most of the absorbent liquid, thereby allowing the air conditioner to reach the steady state quickly. The specific operation method will be described in the following control method of the air conditioner.

4 is a flowchart illustrating a method of operating an absorption air conditioner according to a temperature of a heat storage tank used as a heat source of a high temperature regenerator in an absorption air conditioner using solar heat according to the present invention.

Since the solar heat absorbing air conditioner according to the present invention uses the sun as a heat source, it may be reproduced when sufficient solar light is not secured due to factors such as weather and season. It is necessary to select the operation appropriately in such a case. To this end, the present invention measures the temperature of the heat storage tank and controls a method of selecting an operation method according to the temperature of the heat storage tank and the duration of the corresponding temperature.

First, the solar air conditioner is operated in step 410, and then the temperature of the solar heat storage tank is measured in step 420. As a result of the measurement, if the temperature of the heat storage tank is lower than the reference value (for example, 70 degrees), a situation may be reproduced that is not suitable for operation with the heat storage tank, in which case it is necessary to operate using an external heat source.

In some cases, however, the solar condition may recover and the heat of the heat storage tank may be high enough. For this case, set a timer (step 440) to count the time when the temperature of the heat storage tank is lower than the set value for a predetermined time (for example, 1 minute). If continued, before the heat source is changed, dissolution operation is performed to prevent partial absorption of the absorbent liquid due to the lack of the heat source (step 460).

The reason for the dissolution operation is to improve the solar condition again during the dissolution operation, so that the temperature of the heat storage tank can be restored, and in this case, to prevent crystallization of the absorbent liquid to facilitate the quick conversion to the operation using solar heat as a heat source.

Meanwhile, the second timer is driven at the same time as the melting operation (step 460). This is to determine the reference point to operate as an external heat source because the sunlight is not recovered. If the temperature of the heat storage tank is not recovered even after the second timer expires, the high temperature regenerator is operated as an external heat source.

When performing the operation method according to the invention it is possible to minimize the use of the external heat source can be quickly returned to the normal state by placing the melting operation in the intermediate process.

5 is a flowchart illustrating an efficient control method for reducing energy consumption and preventing absorption liquid determination by measuring cooling water inlet temperature and absorbent liquid concentration and temperature.

The temperature of the cooling water inlet is measured during the absorption air conditioner operation (step 510). Depending on whether the measured coolant inlet temperature is included in the preset first section (eg, 19-28 degrees) (step 520), if the coolant inlet temperature is lower than the lower limit of the first section, the absorbent is less likely to crystallize. In order to maximize the heat exchange effect, the absorbed liquid circulation is increased (step 521). If the coolant inlet temperature is included in the first section, it is determined that the current operating state is normal and maintains the absorbed liquid circulation amount (step 522). However, if it is higher than the upper limit of the first section, since the effect of heat exchange is low, the amount of circulation of the absorbent liquid is reduced (step 523).

Meanwhile, if the cooling water inlet temperature is included in the second section, which is another temperature section, it is measured (step 540). If it is included in the second section, the absorbent concentration is measured (step 550). If the absorbent concentration is higher than the set value, the absorbent liquid may be crystallized. The heat input is maintained (step 563). On the other hand, if the cooling water inlet temperature is lower than the lower limit of the second section in step 540, the absorption liquid is unlikely to crystallize, thereby increasing the heat input of the high temperature regenerator (step 561). However, if it is higher than the upper limit of the second section, the heat input amount of the high temperature regenerator is reduced to prevent crystallization of the absorbent liquid (step 562).

6 is a flowchart of a control method during melting operation according to the present invention.

Melting operation according to the present invention can be used after the operation stop of the air conditioner or at the time of the melt operation according to Figure 4 is shown mainly during the operation stop for convenience of description.

However, by replacing the operation stop in step 610 with the start of the melt operation as described in FIG.

If a predetermined time has elapsed after the operation is stopped in step 620, the concentration of the absorbent liquid is measured to start the dissolution operation when it is lower than the reference value, and the valve and the pump for the dissolution operation of FIG. 3 are started (step 641). . That is, by opening the dissolution pump and the dissolution valve and forcibly transferring the absorbent liquid from the absorber to the high temperature regenerator by using the dissolving pump, exchanging the absorbent liquid exchanged in the high temperature regenerator through the low temperature heat exchanger and circulating back to the absorber. By passing through the circulation line directly connecting the low temperature heat exchanger it is possible to quickly dissolve the crystallized or high concentration of the absorbent liquid.
