Description

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to an adsorption type air-

The present invention relates to an air conditioner for a suction type vehicle, and more particularly, to a configuration in which a radiator for adsorption air conditioning can be utilized as a radiator for cooling engine cooling water, if necessary, thereby reducing the load on the engine radiator, And to reduce the size of the engine radiator so as to secure a space for installing the radiator for adsorption air conditioning.

In recent years, there have been various developments of eco-friendly vehicle air conditioners that can increase the fuel efficiency of the vehicle, generate no pollutants, and have little noise and vibration. As one example thereof, there is a suction type air conditioner.

As shown in FIG. 1, the adsorption-type air conditioning apparatus includes an evaporator 1, first and second adsorbers 3 and 5, and a second adsorber 5 as shown in FIG. 1 for cooling the interior of the vehicle using the heat of vaporization generated in the process of adsorbing refrigerant. , A condenser (7), and an indoor heat exchanger (9).

The evaporator (1) has an internal passage (1a) in which the first refrigerant is stored and in which the second refrigerant can be introduced and flowed.

The first and second adsorbers 3, 5 contain a solid adsorbent such as silica gel, zeolite or the like and adsorb the first refrigerant alternately stored in the evaporator 1. Accordingly, the first refrigerant of the evaporator 1 is vaporized and the heat of the second refrigerant flowing along the internal passage 1a is taken away. As a result, the second refrigerant in the inner passage 1a is cooled.

Here, when one of the first and second adsorbers 3 and 5 adsorbs the first refrigerant of the evaporator 1, the other one desorbs the first refrigerant adsorbed. This is because, immediately after one adsorption action is completed, the other adsorption action can be continuously performed. Thereby, the cooling action of the evaporator 1 can be continued without interruption.

The condenser 7 introduces the first refrigerant desorbed from any one of the first and second adsorbers 3 and 5, condenses it, and liquefies it. Then, the liquefied first refrigerant is returned to the evaporator (1).

Here, the cold fluid cooled by the radiator 10 is introduced into the condenser 7 and circulated. The first coolant of the condenser 7 is condensed by the cold air of the circulating cold fluid.

The indoor heat exchanger (9) introduces the second refrigerant cooled by the evaporator (1), and then exchanges heat between the introduced second refrigerant and the air blown into the passenger compartment. Thus, the air blown into the passenger compartment is cooled. Thus, the interior of the vehicle is cooled.

The adsorption-type air conditioning apparatus is provided with an adsorption-desorption control apparatus (20) for controlling adsorption and desorption operations of the first and second adsorbers (3, 5).

The suction and desorption control apparatus 20 includes a radiator 10 for providing a cold fluid as a refrigerant adsorption inducing material and an engine 22 for providing a hot fluid as a refrigerant desorption inducing material And a plurality of directional control valves 24 for controlling the flow direction of the cold fluid of the radiator 10 and the flow direction of the on fluid of the engine 22 to supply the coolant to the first and second adsorbers 3 and 5 respectively .

Particularly, the directional control valves 24 are controlled in the "first mode" and the "second mode". At this time, in the "first mode", the coolant of the radiator 10, which is discharged from the condenser 7, 1 adsorber 3, and the on-fluid supplied from the engine 22 is introduced into the second adsorber 5. [ Therefore, the adsorption action can be performed in the first adsorber 3 and the desorption action can be performed in the second adsorber 5.

Conversely, in the "second mode ", the cool fluid of the radiator 10 discharged from the condenser 7 is introduced into the second adsorber 5. The on fluid supplied from the engine 22 is introduced into the first adsorber 3, . Therefore, desorption action can be performed in the first adsorber 3, and adsorption action can be performed in the second adsorber 5.

According to the adsorption type air conditioner having such a constitution, since the interior of the vehicle is cooled by using the environmentally friendly adsorbent, there is no generation of contaminants. Therefore, it reduces pollution of the environment.

In addition, since no compressor is used, noise, vibration, and energy consumption are very small. Therefore, it is possible to improve the riding comfort of the passenger compartment and to reduce the fuel consumption.

The conventional adsorption type air conditioner is equipped with the radiator 10 for supplying the cold fluid to the condenser 7 and the first and second adsorbers 3 and 5 and therefore it is necessary to separately install the radiator 10 There is a disadvantage in that the installation space of the apparatus is required.

Particularly, the radiator 10 (hereinafter referred to as "radiator 10 for adsorption air conditioning") of the adsorption type air conditioner must be installed at the front part of the engine room in order to improve the cooling performance, The cooling radiator 22a (hereinafter, referred to as the engine radiator 22a) is provided, so that it is difficult to provide a separate installation space.

In view of such disadvantages, it is very difficult and difficult to install the radiator 10 for adsorption air conditioning. Due to such a problem, the size of the engine room is designed to be large so as to secure the space for installing the radiator 10 for adsorption- There is a drawback.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a radiator for cooling an engine cooling water and a radiator for cooling an engine cooling water, Thereby reducing the size of the radiator for the engine in accordance with the reduced load, and an object of the present invention is to provide an air conditioner for a suction type vehicle.

It is another object of the present invention to provide an air conditioner for a suction type vehicle which is structured so as to be able to reduce the size of a radiator for an engine, thereby securing an installation space of the radiator for adsorption air conditioning.

It is still another object of the present invention to provide an adsorption-type air conditioner for a suction-air-conditioner which is capable of securing a space for installing a radiator for adsorption-air conditioning, so that the radiator for adsorption-air conditioning can be easily installed without forming a large engine room.

Preferably, the fluid control means includes: a first directional control valve capable of simultaneously controlling a flow of cold fluid flowing into the radiator for adsorption air conditioning and a flow direction of engine cooling water discharged from the engine radiator; And a second directional control valve capable of controlling the flow direction of the fluid discharged from the radiator for adsorption air conditioning, wherein when the adsorption-type air conditioning apparatus is turned off, The flow of the cold fluid flowing into the adsorption air-conditioning radiator in the first and second adsorbers is restricted and the engine cooling water discharged from the engine radiator is controlled to be directed toward the inlet side of the radiator for adsorption air conditioning, The engine cooling water discharged from the radiator for the engine is directionally controlled and introduced into the engine; Wherein when the adsorption-type air conditioning apparatus is turned on, the first and second adsorbers allow the flow of cold fluid to flow into the radiator for adsorption air-conditioning, and when flowing into the radiator for adsorption- The engine cooling water is introduced into the engine by direction control and the cold fluid discharged from the radiator for adsorption air conditioning is controlled to be introduced toward the first and second adsorption units.

According to the air-conditioning apparatus for a suction-type vehicle according to the present invention, since a radiator for use in an adsorption air-conditioning system which is not used when the adsorption type air conditioner is turned off is used as a radiator for cooling engine cooling water, the load of the engine radiator can be reduced, It is possible to reduce the size of the engine radiator to meet the reduced load.

Further, since the structure for reducing the size of the radiator for engine can be reduced, there is an advantageous effect in securing the installation space of the radiator for adsorption air conditioning.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of an air conditioner for a suction type vehicle according to the present invention will be described in detail with reference to the accompanying drawings (the same components as those in the prior art are denoted by the same reference numerals).

First, a description will be given of an air conditioner for a suction type vehicle with reference to FIG. 2 before a characteristic portion of a suction type air conditioner for a vehicle according to the present invention is examined.

The adsorption type air conditioner for an adsorption type vehicle comprises an evaporator 1, first and second adsorbers 3 and 5, a condenser 7 and an indoor heat exchanger 9.

The evaporator (1) has an internal passage (1a) in which the first refrigerant is stored and in which the second refrigerant can be introduced and flowed.

The first and second adsorbers (3, 5) contain a solid adsorbent and alternately adsorb the first refrigerant stored in the evaporator (1). Therefore, the first refrigerant of the evaporator 1 is vaporized, and the second refrigerant of the internal passage 1a can be cooled. Here, when one of the first and second adsorbers 3 and 5 adsorbs the first refrigerant of the evaporator 1, the other one desorbs the first refrigerant adsorbed.

The condenser 7 introduces the first refrigerant desorbed from any one of the first and second adsorbers 3 and 5, condenses it, and liquefies it. Then, the liquefied first refrigerant is returned to the evaporator (1). Thus, the first refrigerant is circulated.

Here, the cold fluid cooled in the radiator 10 is introduced into the condenser 7 and circulated. The first refrigerant in the condenser 7 is condensed because of the circulating cold fluid.

The indoor heat exchanger (9) introduces the second refrigerant cooled by the evaporator (1), and then exchanges heat between the introduced second refrigerant and the air blown into the passenger compartment. Thus, the air blown into the passenger compartment is cooled. Thus, the interior of the vehicle is cooled.

The adsorption-type air conditioning apparatus is provided with an adsorption-desorption control apparatus (20) for controlling adsorption and desorption operations of the first and second adsorbers (3, 5).

The intake and exhaust control apparatus 20 includes a radiator 10 for providing a cool fluid, an engine 22 for providing an on-fluid, And a plurality of directional control valves 24 for controlling the directional control valves 24.

The directional control valves 24 are controlled in the "first mode" and the "second mode". At this time, in the "first mode", the cold fluid of the radiator 10 discharged from the condenser 7 is introduced into the first adsorber 3, and the on fluid of the engine 22, 2 adsorber (5). Therefore, the adsorption action can be performed in the first adsorber 3 and the desorption action can be performed in the second adsorber 5.

Conversely, in the "second mode ", the cold fluid of the radiator 10 discharged from the condenser 7 is introduced into the second adsorber 5, and the on fluid of the engine 22, 1 adsorber (3). Therefore, desorption action can be performed in the first adsorber 3, and adsorption action can be performed in the second adsorber 5.

On the other hand, in the "first mode" and the "second mode", the on fluid discharged from the first adsorber 3 or the second adsorber 5 is supplied to the engine radiator 22a before returning to the engine 22, And the cooled fluid is circulated while being supplied to the first adsorber 3 or the second adsorber 5 after being heated while being introduced into the engine 22.

Next, the feature of the air conditioner for a car according to the present invention will be described in detail with reference to Fig.

First, the present invention includes an air conditioner sensing means 30 for sensing the on / off state of the adsorption type air conditioner.

The air conditioner detecting means 30 is constituted by an air conditioner ON / OFF switch (not shown).

The air conditioner on / off switch detects whether the air conditioner is on or off by outputting an "air conditioner ON" signal or an "air conditioner OFF" signal when the user turns on or off the adsorption air conditioner.

In the case of an air conditioner of an automatic control system, the air conditioner detecting means 30 may be constituted by an automatic control unit (not shown).

The automatic control unit turns on / off the adsorption type air conditioner according to the temperature inside or outside the vehicle, and outputs an "air conditioner on signal" or an "air conditioner off signal" to detect on / off of the air conditioner.

The air conditioner of the present invention includes a control unit (40).

The control unit 40 is equipped with a microprocessor. When the "air conditioner off signal" is inputted from the air conditioner detecting means 30, the control unit 40 judges that the present adsorption air conditioner is turned off and outputs a "first control signal".

When the air conditioner detecting means 30 receives the "air conditioner on signal ", it judges that the adsorption air conditioner is currently operated and outputs a" second control signal ".

The air conditioner of the present invention includes valve means (50) for controlling the flow direction of the on-fluid, that is, the engine coolant in accordance with the "control signal"

The valve means 50 includes a first directional control valve 52 provided between the outlet side of the engine radiator 22a and the inlet side of the radiator 10 for adsorption air conditioning, And a third directional control valve 56 provided on the outlet side of the engine 22. The second directional control valve 54 is provided on the side of the engine 22,

The first directional control valve 52 is a solenoid type four-way valve, and the adsorption type air conditioner is turned off. When the "first control signal" is inputted from the control unit 40, the first directional control valve 52 enters the "adsorption-

The first directional control valve 52 that enters the "adsorption-type air conditioner off mode" restricts the flow of the cold fluid flowing into the adsorption-air conditioning radiator 10 from the first and second adsorbers 3, 5, The engine cooling water discharged from the engine radiator 22a is directionally controlled to the inlet side of the radiator 10 for adsorption air conditioning.

Therefore, the engine cooling water discharged from the engine radiator 22a can be introduced into the radiator 10 for adsorption air-conditioning. Thereby, the engine cooling water primarily cooled in the radiator 22a for engine is introduced into the radiator 10 for adsorption air conditioning, and further cooled down. As a result, the cooling efficiency of the engine cooling water is increased.

The reason why the engine cooling water of the engine radiator 22a is further cooled while introducing the engine cooling water of the engine radiator 22a into the radiator 10 for adsorption air conditioning is that when the adsorption air conditioner is off, 10 is not used, so that the engine cooling water is further cooled by utilizing the unused adsorptive air-conditioning radiator 10.

The reason why the engine cooling water is further cooled by utilizing the adsorption air conditioning radiator 10 is to reduce the size of the engine radiator 22a without affecting the cooling efficiency of the engine cooling water.

The reason for reducing the size of the engine radiator 22a is to provide the engine room portion with a space as much as the reduced portion. This is because the installation space of the radiator 10 for adsorption air- In order to secure. This makes it very advantageous to install the radiator 10 for adsorption air conditioning.

On the other hand, the first directional control valve 52 enters the "adsorption-type air-conditioner on mode" when the adsorption-type air conditioner is turned on and the "second control signal" is inputted from the control unit 40.

The first directional control valve 52 which has entered the "adsorption-type air-conditioner on mode" is a control means for controlling the flow rate of the refrigerant flowing into the radiator 10 for adsorption air-conditioning in the first and second adsorbers 3, The engine cooling water flowing from the engine radiator 22a to the adsorption air conditioning radiator 10 is blocked and the engine cooling water discharged from the engine radiator 22a is directed to the inlet side of the engine 22 .

Therefore, the adsorption air-conditioning radiator 10 can perform the cooling function of the cold fluid circulating inside the adsorptive air conditioner according to the original function.

Here, when the adsorption-type air conditioner is turned on, when the adsorption-air conditioning radiator 10 recovers the cooling-fluid cooling function of the adsorption-type air conditioner according to the original function, only the engine radiator 22a At this time, when the size of the engine radiator 22a is reduced as described above, there is a possibility that the cooling efficiency of the engine cooling water is lowered.

However, since the engine coolant is sufficiently cooled while passing through the first adsorber 3 or the second adsorber 5 of the adsorptive air conditioner after being discharged from the engine 22, even if the size of the engine radiator 22a is reduced Sufficiently compensated. Therefore, the reduction of the cooling performance of the engine cooling water due to the reduction of the size of the engine radiator 22a does not occur.

The second directional control valve 54 is a solenoid type three-way valve. When the adsorption type air conditioner is turned off and the "first control signal" is inputted from the control unit 40, the second directional control valve 54 enters the "adsorption air conditioner off mode".

The second directional control valve 54, which has entered the "adsorption type air conditioner off mode", controls the flow direction of the engine cooling water discharged from the radiator 10 for adsorption air conditioning to the inlet side of the engine 22.

Therefore, when the adsorption type air conditioner is turned off, the cooled engine cooling water passes through the engine radiator 22a and the adsorption air conditioning radiator 10 so that the cooled engine cooling water can be circulated to the engine 22 side without being introduced into the adsorption type air conditioner . Thus, the cooling function of the engine 22 can be continuously performed.

On the other hand, when the adsorption type air conditioner is turned on and the "second control signal" is inputted from the control unit 40, the second direction control valve 54 enters the "adsorption type air conditioner on mode".

The second directional control valve 54 that has entered the "adsorption-type air conditioner on-mode" controls the flow direction of the cold fluid discharged from the radiator 10 for adsorption air conditioning to the side of the condenser 7 of the adsorption- do.

Therefore, the adsorption-air conditioning radiator 10 can perform the cooling-fluid cooling function of the adsorption-type air conditioner according to the original function.

The third directional control valve 56 is a solenoid type three-way valve, and the adsorption type air conditioner is turned off. When the "first control signal" is inputted from the control unit 40, the third directional control valve 56 enters the "

The third directional control valve 56, which has entered the "adsorption air conditioner off mode", controls the flow direction of the engine cooling water discharged from the engine 22 to the inlet side of the engine radiator 22a.

Therefore, when the adsorption type air conditioner is turned off, the engine cooling water discharged from the engine 22 is introduced into the engine radiator 22a and the radiator 10 for adsorption air conditioning, without introducing the engine cooling water into the adsorption type air conditioner side. Thereby, the engine cooling water is controlled so that it can be exclusively used only for cooling the engine 22.

On the other hand, the third directional control valve 56 enters the "adsorption-type air conditioner on mode" when the adsorption-type air conditioner is turned on and the "second control signal" is inputted from the control unit 40.

The third directional control valve 56, which has entered the "adsorption-type air conditioning on mode", controls the flow direction of the engine cooling water discharged from the engine 22 to the adsorption-type air conditioning side in the original state.

Thus, the engine cooling water discharged from the engine 22 is introduced to the adsorption-type air conditioning side. Particularly to the first and second adsorber 3, 5 side. This enables the engine coolant to induce the refrigerant desorption action in the first and second adsorbers 3, 5.

Next, an operation example of the present invention having such a configuration will be described with reference to Figs. 3 and 4. Fig.

First, the case where the adsorption type air conditioner is "off" will be described with reference to Fig.

When the adsorption type air conditioner is turned "off ", the control unit 40 outputs a" first control signal ".

When the "first control signal" is outputted from the control unit 40, the first to third directional control valves 52, 54, and 56 enter the "adsorption air conditioner off mode".

The first to third directional control valves 52, 54 and 56 which enter the adsorption type air conditioner off mode are connected to the adsorption air conditioning radiator 10 through the first and second adsorbers 3 and 5, The flow of the fluid is limited and the engine cooling water discharged from the engine radiator 22a is controlled to the inlet side of the radiator 10 for adsorption air conditioning and the engine cooling water discharged from the radiator 10 for adsorption air conditioning is supplied to the engine 22 To the inlet side. In addition, the engine cooling water discharged from the engine 22 is controlled to the inlet side of the engine radiator 22a.

Therefore, the engine cooling water discharged from the engine 22 is cooled while passing through the engine radiator 22a and the adsorption air conditioning radiator 10 in order, and the cooled engine cooling water is introduced into the engine 22 again, .

As a result, the engine cooling water discharged from the engine 22 at the time of the "adsorption-type air conditioning off mode" is supplied to the engine 22, the engine radiator 22a and the radiator 10 for adsorption- And is cooled through the engine radiator 22a and the adsorption air-conditioning radiator 10 during the circulation.

As a result, it is possible to reduce the size of the engine radiator 22a in accordance with the first and second cooling. As a result, it is very advantageous in securing the installation space of the radiator 10 for adsorption air conditioning.

Next, the case in which the adsorption type air conditioner is turned "on " will be described with reference to Fig.

When the adsorption type air conditioner is turned "on ", the control unit 40 outputs a" second control signal ".

When the control unit 40 outputs the second control signal, the first to third directional control valves 52, 54, and 56 enter the adsorption-type air conditioner on mode.

The first to third directional control valves 52, 54 and 56 enter the adsorption-type air conditioner on-mode so that the refrigerant flowing into the radiator 10 for adsorption air-conditioning in the first and second adsorbers 3, The engine cooling water discharged from the radiator for adsorption and conditioning 10 is supplied to the condenser 7 side of the adsorption type air conditioner . The engine cooling water discharged from the engine 22 is controlled to the first and second adsorbers 3 and 5 of the adsorption type air conditioner.

Accordingly, the engine cooling water discharged from the engine 22 is introduced into the first and second adsorbers 3 and 5 of the adsorption type air conditioner, thereby inducing the desorption action of the refrigerant. The radiator 10 for adsorption air-conditioning cools the cold fluid of the adsorption-type air conditioner according to the original function.

According to the air conditioner of the present invention having such a configuration, when the suction type air conditioner is turned off, the unused adsorptive air conditioner radiator 10 is used as a radiator for cooling engine cooling water. The load can be reduced, thereby reducing the size of the radiator for the engine to a reduced load.

Furthermore, since the structure of the engine radiator 22a can be reduced, it is very advantageous in securing the installation space of the radiator 10 for adsorption air conditioning.

Furthermore, since the air is very advantageous in securing the installation space of the radiator 10 for adsorption air conditioning, the radiator 10 for adsorption air conditioning can be easily installed without greatly designing the engine room.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, is intended to cover various modifications and equivalent arrangements included within the spirit and scope of the invention.
