Description

  The present invention relates to an air conditioner, and more particularly to an air conditioner that performs dehumidification, humidification, cooling, and heating of air.

  A vehicle air conditioner is required to have a dehumidifying performance for removing and preventing fogging of the window glass, in addition to cooling and heating in the passenger compartment.

  Such an air conditioner performs cooling that also serves as dehumidification by supercooling the air sent from the refrigeration cycle (mechanical compression heat pump) to a dew point temperature or less to condense moisture. However, because of this supercooling of the air, it is necessary to enlarge the refrigeration cycle, which occupies a large weight in the vehicle weight. In addition, the refrigeration cycle has a large load on the engine, which is a factor that deteriorates fuel consumption in the conventional air conditioning for vehicles. In addition, conventional vehicle air conditioners usually heated air by applying air to engine cooling water to raise the temperature of the air during heating. There is a need for dehumidification to drive the refrigeration cycle, and for the passengers, there was a background that caused discomfort such as thirst. On the other hand, in the vehicle interior air conditioning, a dehumidifying agent is installed to separate the dehumidifying function of the refrigeration cycle, or the air is dehumidified and humidified using a dehumidifying agent or an adsorbent. It has been proposed to do.

Conventionally, some air conditioners for vehicles use an electric heater as a heater for regenerating a heat exchanger having a dehumidifying function.
Some vehicle air conditioners circulate inside air and exchange a part of the inside air and outside air at a predetermined ratio without changing the air blowing conditions.

Specifically, when the first mode is selected by the introduction-side four-way valve 52, as shown in FIG. 1, when the air-conditioning apparatus 4 is dehumidified and cooled, and the second mode is selected by the introduction-side four-way valve 52, As shown in FIG. 5, the air conditioner 4 is set to the humidifying and heating operation, and after the first mode is selected by the introduction side four-way valve 52, the air conditioner 4 is set to the cloudy operation as shown in FIG.

  Although not shown, the air conditioner 4 is driven using a power source such as a 12V lead battery.

  Next, the operation of this embodiment will be described.

  In the operation of the air conditioner 4, the dehumidifying and cooling operation, the humidifying and heating operation, and the like can be realized by switching the introduction side four-way valve 52 and the discharge side four-way valve 54. The basic operation is performed by introducing the outside air from the second introduction passage 62 into the vehicle. This is because carbon dioxide accumulates in the passenger compartment and does not cause discomfort to the passengers.

  In the dehumidifying and cooling operation of the air conditioner 4, the air conditioner 4 is operated in the state of the air conditioner 4 in FIG. 1 and the air temperature and absolute humidity state diagram in FIG. 4. This dehumidifying and cooling operation is used when the temperature setting request from the occupant is lower than the current value of the internal air temperature sensor 96 and the humidity setting request is lower than the current value of the internal humidity sensor 98.

  During this dehumidifying and cooling operation, the introduction-side four-way valve 52 and the discharge-side four-way valve 54 are switched as shown by the solid line in FIG. In this state, outside air (point A in FIG. 4) from the second introduction passage 62 is taken into the dehumidification passage 22, and inside air (point E in FIG. 4) from the first introduction passage 60 to the humidification passage 26. ) Is captured.

  When the refrigeration cycle 16 is operated, as shown in FIG. 4, first, the outside air from the second introduction passage 62 at point A is sent into the temperature control device 6 by the first blower fan 8, and the processing of the desiccant rotor 12 is performed. Pass through side 30. When the outside air passes through the processing side 30, it comes into contact with the dehumidifying agent inside the desiccant rotor 12 and is dehumidified. At this time, the air at point A undergoes a state change during the isoenthalpy process, causing a temperature rise and a decrease in absolute humidity, and becomes a point B state. The air at this point B is introduced into the heat exchanger 14 and exchanges heat with the air at point E sent to the humidification path 26. The air at this point E is the inside air from the first introduction passage 60 introduced into the temperature control device 6 by the second blower fan 10. The air at the point B dissipates heat to the air at the point E, the temperature is lowered, and the state of the point C is obtained.

  Conversely, the air at point E absorbs heat and enters the state of point F. The air at point C passes through the evaporator 46, absorbs heat, enters the state of point D, and is discharged from the temperature control device 6 toward the discharge side four-way valve 54. The exhaust side four-way valve 54 selects the vehicle compartment exhaust passage 72 as a route for blowing out the air that has passed through the dehumidification passage 22 into the vehicle as temperature-controlled air, as indicated by the solid line in FIG. Air is blown out into the vehicle through the ventilation port 56-2 which is not blocked by the mode doors 58 and 58. The air at this point D becomes low-temperature and low-humidity air as compared with the air at point E that was air from the first introduction passage 60, and the inside of the vehicle can be dehumidified and cooled.

  On the other hand, the air at the point F of the humidifying passage 26 passes through the condenser 40 and is heated to the state of the point G, and is further introduced into the heater core 20 and further heated by the cooling water of the engine 2. Become. The air at this point H passes through the regeneration side 32 of the desiccant rotor 12 and deprives the moisture absorbed on the processing side 30. That is, the air at the point H passes through the regeneration side 32, thereby causing a state change in the isoenthalpy process, causing a temperature drop and an absolute humidity rise, and becoming a point I state. It is discharged towards the valve 54.

  The regeneration side 32 of the desiccant rotor 12 can recover the moisture absorption capacity again by rotating through the high-temperature air, rotate and move to the processing side 30, and dehumidify the air that has entered the dehumidifying path 22. Further, the air at the point I that has passed through the humidifying path 26 is distributed as exhausted air to the outdoor exhaust passage 74 in the exhaust side four-way valve 54 as shown by the solid line in FIG. The

  Then, the air at point D enters the vehicle, and after the passenger and the passenger compartment are cooled, the air is sent to the humidification route 26 as the internal air from the first introduction passage 60. Assuming that the air at this time is a point D ′, the air at the point D ′ is heat-exchanged with the air at the point B in the heat exchanger 14. In comparison, since the air at point D ′ is at a low temperature, the heat exchange efficiency is increased, and the air at point B can dissipate a large amount of air. Can be introduced.

  However, if the air conditioner is excessively cooled, the passenger may feel discomfort due to the cold temperature in spring or autumn. In this case, by changing the operating rate of the refrigeration cycle 16, the temperature of the evaporator 46 is adjusted, and the discomfort is eliminated. Specifically, the air at the point C is cooled by the evaporator 46 to be the air at the point D. If the refrigeration cycle 16 is not operated, the air at the point C is directly conditioned and introduced into the vehicle. Is also possible. That is, the air between the point C and the point D can be selectively introduced from the ventilation port 56-2 according to the operating rate of the refrigeration cycle 16, and the temperature can be adjusted. The operating rate of the refrigeration cycle 16 can be controlled by the on-time of the magnet clutch 36.

  In the above method, fresh air taken in from the outside air from the second introduction passage 62 can always be introduced into the vehicle. However, this is not the case when the outside air from the second introduction passage 62 is not fresh. That is, the occupant may request through the air conditioner panel 80 that the outside air from the second introduction passage 62 wants to be cooled by the inside air circulation due to problems such as bad odor. In this case, the inside / outside air actuator 104 may be operated so as to operate the introduction-side four-way valve 52 and introduce the inside air from the first introduction passage 60 into the dehumidification path 22. As a result, the inside air from the first introduction passage 60 can pass through the processing side 30 of the desiccant rotor 12, the evaporator 46, and the like in the dehumidification path 22, and is dehumidified and cooled. The dehumidified and cooled air operates the discharge-side four-way valve 54, communicates with the indoor discharge passage 72, and selects a path to blow out into the vehicle as temperature-controlled air, thereby achieving an inside air circulation path.

  In the humidifying and heating operation of the air conditioner 4, the air conditioner 4 is operated in the state of the air conditioner 4 in FIG. 5 and the air temperature and absolute humidity state diagram in FIG. 6. This humidifying heating operation is used when the temperature setting request from the passenger is higher than the current value of the internal air temperature sensor 96 and the humidity setting request is higher than the current value of the internal humidity sensor 98.

  During this humidification heating, the refrigeration cycle 16 is not driven. During the humidifying heating operation, the introduction side four-way valve 52 and the discharge side four-way valve 54 are switched as shown by the solid line in FIG. In this state, the inside air (point J in FIG. 6) from the first introduction passage 60 is taken into the dehumidification path 22, and the outside air (point M in FIG. 6) from the second introduction path 62 is taken into the humidification path 26. ) Is captured.

  At the time of humidification heating, as shown in FIG. 6, first, the inside air from the first introduction passage 60 at point J is sent into the temperature control device 6 by the first blower fan 8 and passes through the processing side 30 of the desiccant rotor 12. Then, when passing through the processing side 30, it comes into contact with the internal dehumidifying agent and is dehumidified. At this time, the air at point J undergoes a state change in the isoenthalpy process, causing a temperature rise and a decrease in absolute humidity, and becomes a point K state. The air at this point K is introduced into the heat exchanger 14 and exchanges heat with the air at point M sent to the humidification path 26. The air at this point M is the air from the second introduction passage 62 introduced into the temperature control device 6 by the second blower fan 10. The air at this point K radiates heat to the air at point M, and the temperature drops to a state at point L.

  On the contrary, the air at this point M is absorbed by heat and becomes the state at point N. The air at the point L passes through the evaporator 46, but the refrigeration cycle 16 is not driven during the humidification heating, and is thus discharged from the temperature control device 6 toward the discharge side four-way valve 54 without temperature change. As shown by the solid line in FIG. 5, the discharge-side four-way valve 54 selects the vehicle external discharge passage 74 as a route for releasing the air that has passed through the dehumidification passage 22 as discharge air to the outside of the vehicle. Is released outside the vehicle.

  On the other hand, the air at the point N in the humidification path 26 passes through the condenser 40, but since the refrigeration cycle 16 is not driven during humidification heating, the air is introduced into the heater core 20 without temperature change. It is heated by the cooling water of No. 2 and becomes a state of point O. The air at this point O passes through the regeneration side 32 of the desiccant rotor 12 and takes away moisture absorbed by the processing side 30. In other words, the air at the point O passes through the regeneration side 32, thereby causing a state change in the isoenthalpy process, causing a temperature drop and an absolute humidity rise, and becoming a point P state. It is discharged towards the valve 54.

  The regeneration side 32 of the desiccant rotor 12 can recover the moisture absorption capability again by passing the high-temperature air, rotate and move to the processing side 30, and dehumidify the air that has entered the dehumidifying path 22. The air at point P blown out from the humidification path 26 passes through the path indicated by the solid line of the discharge side four-way valve 54 and is blown into the vehicle as temperature-controlled air. The air at the point P is blown into the vehicle from the foot opening 56-3 not blocked by the mode doors 58 and 58 in FIG. The air at this point P becomes hot and humid air as compared with the air at point M, which is the air inside the air from the first introduction passage 60, and the vehicle interior can be humidified and heated.

  Then, the air at point P enters the vehicle, and after the passenger and the vehicle interior are heated, the air is sent to the dehumidification route 22 as the internal air from the first introduction passage 60. Assuming that the air at this time is a point P ′, the air at this point P ′ enters the processing side 30 of the desiccant rotor 12 and is dehumidified by the dehumidifying agent to become the air at the point Q. The air at this point Q exchanges heat with the air at point M in the heat exchanger 9. Compared to the air at point K that was initially heat-exchanged, the air at point Q has a high temperature, so the heat exchange efficiency is increased, and the air at point M can absorb a large amount of heat. It becomes possible to introduce air having a temperature higher than that of air into the vehicle.

  In this method, it can always be introduced into the vehicle as fresh air taken in from the second introduction passage 62. However, this is not the case when the outside air from the second introduction passage 62 is not fresh. In other words, the occupant may request through the air conditioner panel 80 that the outside air from the second introduction passage 62 wants to heat the inside air circulation due to problems such as bad odor. In this case, the inside / outside air actuator 104 may be operated so that the introduction side four-way valve 52 is operated and the inside air from the first introduction passage 60 is introduced into the humidification passage 26. As a result, the inside air from the first introduction passage 60 can pass through the heater core 20, the regeneration side 32 of the desiccant rotor 12, and the like in the humidification path 26, and is humidified and heated. By operating the discharge side four-way valve 54 and selecting a route for the humidified and heated air to be blown into the vehicle as temperature-controlled air, an inside air circulation route can be achieved.

  In the anti-fogging operation of the air conditioner 4, the air conditioner 4 is operated in the state of the air conditioner 4 in FIG. 7 and the air temperature and absolute humidity state diagram in FIG. 4.

In this state, outside air (point A in FIG. 4) from the second introduction passage 62 is taken into the dehumidification passage 22, and inside air (point E in FIG. 4) from the first introduction passage 60 to the humidification passage 26. ) Is captured.

  In addition, the refrigeration cycle 16 performs control to change the operating rate depending on the situation. This anti-fogging operation is the same as the dehumidifying and cooling operation described above, and may be operated so as to select the defroster port 56-1 as the temperature-controlled air outlet. However, if cooling is performed, there is a possibility that the passengers may feel discomfort due to the cold temperature in spring or autumn. In this case, by changing the operating rate of the refrigeration cycle 16, the temperature of the evaporator 46 is adjusted and the discomfort is eliminated. Specifically, the air at the point C is cooled by the evaporator 46 to be the air at the point D, but if the refrigeration cycle 16 is not operated, the air at the point C is directly introduced into the vehicle as temperature-controlled air. Is also possible. That is, depending on the operating rate of the refrigeration cycle 16, air between point C and point D can be selectively introduced from the defroster port 56-1 and temperature adjustment can be performed. The operating rate of the refrigeration cycle 16 can be controlled by the on-time of the magnet clutch 36.

Can be optimally controlled, and energy can be saved.

  Of course, the present invention is not limited to the above-described embodiments, and various modifications can be made as shown in the following modifications.

  As a first modification, regarding the above-described anti-fogging operation, it is also required to perform heating while dehumidifying in winter. In this case, as shown in FIG. 8, in the air conditioner 4, mode switching means for switching between a normal cycle mode M1 in which the compressor 38 and the condenser 40 are connected and a hot gas cycle mode M2 in which the compressor 38 and the evaporator 46 are connected. The switching valve 202 may be provided in a passage 204 connecting the compressor 38 and the condenser 40, and the refrigeration cycle 16 may be controlled by the switching valve 202 so that the air passing through the evaporator 46 can be heated.

  Specifically, a switching valve 202 is newly provided, the switching valve 202 can be driven by an actuator such as a motor, and the refrigeration cycle 16 has two paths. That is, in the state where the switching valve 202 is indicated by a broken line in FIG. 8, the refrigeration cycle 16 is in the normal cycle mode M1, and has a normal function. However, when the switching valve 202 is in the state indicated by the solid line in FIG. 8, the hot gas cycle M <b> 2 is established, and a path that does not pass through the capacitor 40, the receiver 42, and the expansion valve 44 can be obtained.

  That is, the refrigerant compressed by the compressor 38 directly enters the evaporator 46, releases heat by the evaporator 46, and returns to the compressor 38 again. The air passing through the evaporator 46 is heated by the hot gas cycled M2. This state is shown by a state diagram of air temperature and absolute humidity in FIG. In this anti-fogging operation, as shown in FIG. 9, the air at point C is cooled to point D if the refrigeration cycle 16 is in the normal cycle mode M1, but the refrigeration cycle 16 is hot gas cycled M2. By using, it is possible to heat to point R. Thereby, dehumidification heating operation is attained.

  Therefore, in the first modification, the dehumidifying and heating operation can be performed by selecting the hot gas cycle mode M2, and the vehicle interior is cooled even in the winter by simply bypassing a part of the refrigeration cycle 16. Therefore, it is possible to realize the anti-fogging operation.

  As a second modification, as shown in FIG. 10, the capacitor 40 is disposed outside the temperature control device 6 on the front side of the radiator 206. Further, the receiver 42 and the expansion valve 44 are also arranged outside the temperature control device 6, as with the capacitor 40. The capacitor 40 is a device that radiates and liquefies the refrigerant, and relates to the heat absorption efficiency of the evaporator 46.

  Therefore, in the second modification, by disposing the capacitor 40 on the front side of the radiator 206, the heat of the capacitor 40 can be effectively radiated using the vehicle speed wind, and the heat absorption efficiency in the evaporator 46 can be increased. . On the other hand, when the vehicle speed wind cannot be obtained, the radiator fan 208 may be rotated to radiate heat from the capacitor 40.

  As a third modification, as the drive source of the compressor 38, as long as sufficient electric power for driving can be obtained, an electric compressor 210 can be separately used as shown in FIG. Specific examples of the power supply source include a hybrid battery used in a hybrid vehicle, a battery for an automatic electric chapter, and a fuel cell for an automatic fuel cell chapter. A system capable of supplying electric power from these supply sources is created, and the electric compressor 210 is used.

  In the third modified example, the electric compressor 210 can determine the refrigerant compression capacity by electric power, so that finer temperature control in the evaporator 46 can be performed. Further, the layout does not have to be directly connected to the engine 2 and can be arranged outside the engine room. Similarly, since it is not directly connected to the engine 2, it is possible to use a vehicle air conditioner that is capable of idling stop.

  Further, as a fourth modified example, at the time of humidification heating, there is a possibility that the window glass in the vehicle interior may be fogged depending on the humidification amount. In such a case, the configuration shown in FIG. 12 may be used so that a part of the air that has passed through the dehumidifying path 22 is blown out from the defroster port 56-1. That is, during the humidifying and heating operation, the air at the point P in FIG. 6 is blown out from the foot port portion 56-3, but a part of the air at the low point L is blown out from the defroster port portion 56-1. Thus, fogging of the window glass can be prevented.

  Specifically, a bypass line 212 as a branch passage connected to the defroster port portion 56-1 may be provided at the outlet of the dehumidifying path 22, and the air volume of the bypass line 212 may be controlled by the bypass line door 214. When the bypass line 212 is not used, the bypass line door 214 is slid and moved to the position indicated by the broken line, so that normal humidification heating operation can be performed without flowing air into the bypass line 212. To enter this control, it is determined whether or not the inside humidity (humidity) obtained from the inside humidity sensor 98 is condensed by the outside air temperature obtained from the outside air temperature sensor 92. Further, a defroster (DEF) / foot (FOOT) mode in which wind is blown simultaneously from the defroster mouth portion 56-1 and the foot mouth portion 56-3 may be selected. Further, the bypass line 212 may be processed as a part of the mode doors 58 and 58 that are normally used.

  In the fourth modified example, when the vehicle interior is humidified and heated, only the front and side windows can be prevented from fogging, so that humidification and heating can be performed without hindering operation.

  In the above embodiment, the air conditioner is limited to a vehicle. However, the air conditioner may be used for air conditioning in a general house, an office, a factory, or the like. In this case, an electric heater or the like may be used as a heat source instead of the heater core. Moreover, the form which can introduce | transduce the exhaust heat of the apparatus which can obtain exhaust heat, such as an engine, a micro gas turbine, and a fuel cell, may be taken. If the refrigeration cycle 16 is a system using an electric compressor, the drive source can be easily obtained.

  The first and second blower fans 8 and 10 do not have to be two, and may be formed so that two blower fans can be independently blown to the two paths of the dehumidification path 22 and the humidification path 26.

  The temperature sensor and the humidity sensor may be unified and arranged as a temperature / humidity sensor module.

  In order to purify contaminated air such as bad odor and cigarette smoke, an air cleaning filter may be provided in the vicinity of the intake port for the inside air and the outside air. Further, the desiccant rotor 12 may be provided with an air cleaning function to replace the filter.

  A button or the like that can set the auto mode may be added to the air conditioner panel 80. In this case, a map or the like that can automatically drive the actuator is stored in the air conditioner control unit 78 from the read value of each sensor, and each operation mode of dehumidifying and cooling operation, humidifying and heating operation, and anti-fogging operation can be automatically operated. Anyway.

  The flow rate of the cooling water of the engine 2 flowing through the heater core 20 may be controlled so that the temperature control during humidification heating can be controlled more finely. Specifically, a control valve that can be electrically controlled is attached to the pipe between the heater core 20 and the engine 2, and the degree of opening of the control valve is controlled by the air conditioner control unit 78 and the like, and the flow rate of the cooling water of the engine 2 is controlled. It ’s fine.

  Control for strengthening cooling may be added based on information from the solar radiation sensor 100. Specifically, when solar radiation enters the vehicle, it enters a state where it directly shines on the upper body of the occupant, causing the arms and face to become hot and uncomfortable. In order to prevent this, by measuring the solar radiation intensity by the solar radiation sensor 100 and controlling the ability of the evaporator 46, it is possible to remove the heat of the arms and face and improve the comfort.

  The scenery blown into the vehicle may be controlled by information from the water temperature sensor 118. At the time of dehumidifying and cooling, if the liquid temperature of the cooling water of the engine 2 is low, the temperature of the wind blown into the regeneration side 32 of the desiccant rotor 12 becomes low, and sufficient dehumidifying agent regeneration cannot be expected. In this case, the air volume is weakened, and the air volume is increased as the liquid temperature rises, so that the regeneration temperature of the dehumidifying agent is increased. Further, at the time of humidifying and heating, if the liquid temperature of the cooling water of the engine 2 is low, cold air comes out into the vehicle, giving an uncomfortable feeling. Also in this case, the air volume is weakened, and the air volume is increased as the liquid temperature rises, and control is performed so as not to cause discomfort. Further, during humidification heating, the refrigeration cycle 16 that is not driven may be temporarily driven, and the temperature of the wind blown into the vehicle may be increased by utilizing the heating by the condenser 40.

  A temperature-controlled air temperature sensor, a temperature-controlled air humidity sensor, or the like may be attached to the temperature-controlled air into the room, and a means for transmitting it as an electric signal to the air conditioner control unit 78 may be provided. In this case, the temperature and humidity of the air blown into the vehicle can be known, the time lag until the set temperature and set humidity are reached can be calculated, and the control of the temperature control device 6 can be set more finely.

  The air conditioner control unit 78 receives information from the vehicle speed sensor 116, the water temperature sensor 118, and the refrigerant pressure sensor 120 through communication with the engine control unit 114, but may be received in some form. That is, the sensor signal may be directly received or may be received by communication from another control unit.

  Proper arrangement of an evaporator, a condenser, a moisture absorbing member (desiccant rotor) capable of desorbing and regenerating moisture, a heat exchanger, a heating source, and the like can also be applied to other devices.
