Description

  The present invention relates to a vehicle air conditioner, and more particularly to a vehicle air conditioner that can blow cool air into a vehicle interior even when a vehicle engine is temporarily stopped to stop driving a compressor.

In recent years, in order to reduce the amount of CO ₂ (carbon dioxide) emitted from the vehicle from the viewpoint of preventing global warming, etc., the vehicle is idling when the vehicle is stopped for a relatively short time, such as waiting for a signal. Vehicles (automobiles) that automatically stop the engine (hereinafter referred to as “idling stop”) have been put into practical use.

  By the way, a vehicle air conditioner mounted on a vehicle drives a compressor (compressor) of a refrigeration cycle by a vehicle engine and cools air flowing through a passage provided with an evaporator to generate a predetermined amount of cold air. Since the air is blown from the exit into the vehicle interior, as described above, when idling is stopped when the vehicle is stopped, such as waiting for a signal, the compressor is also stopped driving, and accordingly, the blowing of cool air into the vehicle interior is also stopped. In this way, when the vehicle engine is idling stopped when the vehicle is stopped, such as when waiting for a signal, the compressor driven by the vehicle engine also stops at the same time, so the temperature of the air blown into the vehicle compartment suddenly rises and the passenger in the vehicle compartment A problem that makes the user feel uncomfortable.

  Therefore, as a countermeasure for air conditioning when the vehicle engine is idling stopped when the vehicle is stopped, such as when waiting for a signal, conventionally, a regenerator that encloses a regenerator material that is stored by cold air obtained by an evaporator when the vehicle engine rotates is installed. A vehicle air conditioner has been proposed in which when the vehicle engine is idling stopped due to waiting for a signal or the like, cold air can be blown into the vehicle interior using latent heat associated with melting of the cold storage material. (For example, refer to Patent Document 1).

In the vehicle air conditioner described in Patent Document 1, an evaporator temperature sensor for measuring the temperature of air (cold air) after passing through the evaporator is disposed downstream of the evaporator (evaporator) in the air flow direction. A regenerator temperature sensor that measures the temperature of the air (cold air) after passing through the regenerator is disposed on the downstream side in the air flow direction. The evaporator temperature sensor is used for adjustment control of the cooling capacity of the evaporator, and the regenerator temperature sensor is used for opening control of an air mix door installed downstream in the air flow direction of the regenerator.

It is necessary to provide an interval (for example, an interval of about 20 mm) greater than the thickness of the sensor fixing member 104a.

  Further, in recent years, there has been a demand for downsizing (compacting) a vehicle air conditioner installed in a vehicle (automobile), and a regenerator 103 is provided on the downstream side of the evaporator 102 in the air flow direction. Also in the above-described vehicle air conditioner in which the evaporator temperature sensor 100 is disposed on the air outlet surface 102a side, it is desired to further reduce the size of the entire apparatus by reducing the interval between the evaporator 102 and the regenerator 103. ing.

  Further, conventionally, the evaporator temperature sensor 100 and the regenerator temperature sensor 101 are separately attached to the air outlet surfaces 102a and 103a of the evaporator 102 and the regenerator 103, respectively, so that the attachment workability is poor. It was.

  Therefore, the present invention also provides an evaporator and a cold accumulator even in a vehicle air conditioner that includes a cold storage heat exchanger on the downstream side in the air flow direction of the evaporator and a temperature sensor is arranged on each air outlet surface side of the evaporator and the cold storage heat exchanger. A vehicle air conditioner that can reduce the space between the heat exchanger and that can be attached to each temperature sensor arranged on each air outlet surface side of the evaporator and the cold storage heat exchanger with good workability.

In the vehicle air conditioner that melts and cools the air blown through the evaporator by using latent heat, the first and second temperature sensors are fixed to one fixing member, and the fixing member is placed at a predetermined position. By installing, the first temperature sensor is simultaneously disposed in the vicinity of the air outlet on the downstream side in the air flow direction of the evaporator, and the second temperature sensor is simultaneously disposed in the vicinity of the air outlet on the downstream side in the air flow direction of the cold storage heat exchanger.

Hereinafter, the present invention will be described based on the illustrated embodiments.
<Embodiment 1>
FIG. 1 is a schematic longitudinal sectional view showing a vehicle air conditioner (hereinafter referred to as “air conditioner”) according to Embodiment 1 of the present invention.

  As shown in FIG. 1, an air conditioner 1 according to the present embodiment has an air conditioning case 2 provided in an instrument panel (not shown) in the front part of the passenger compartment, and an air blow formed in the air conditioning case 2.

The heater core 6 heats the air passing through the heater core 6 using hot water (cooling water) circulated to drive the engine as a heat source.

  An inside / outside air switching door 8 is installed on the downstream side in the air flow direction of the air conditioning case 2 (left side in FIG. 1), and either the inside air introduction port 9a or the outside air introduction port 9b is turned by the rotation of the inside / outside air switching door 8. By selectively switching between, the inside air or the outside air is introduced. In addition, on the downstream side in the air flow direction of the air conditioning case 2 (the right side in FIG. 1), a def door 12 that distributes the temperature-controlled air (air conditioned air) in the air mix chamber 10 to the defroster outlet 11, and a vent blower A vent door 14 that distributes to the outlet 13 and a foot door 16 that distributes to the foot outlet 15 are provided. In FIG. 1, an arrow A indicates the air flow direction.

  The evaporator 4 constitutes a refrigeration cycle together with a compressor, a condenser, a liquid tank, a circulation pipe, and the like driven by an engine (not shown), and air (inside air or outside air) blown to the evaporator 4 side by rotation of the blower fan 3. Heat is exchanged with the refrigerant circulating in the refrigerant tube (not shown) of the evaporator 4 to cool the air passing through the evaporator 4.

  Note that a vehicle (not shown) equipped with the air conditioner 1 according to the present embodiment has an idling stop function, and when a compressor (not shown) is driven to blow cool air into the vehicle interior, Even when the vehicle engine (not shown) is automatically stopped and the compressor (not shown) is stopped when the vehicle is stopped for a relatively short time such as waiting, the cold storage material enclosed in the cold storage heat exchanger 5 described later The cool air blowout can be maintained by the cold storage. Release of the idling stop is automatically performed by releasing the brake operation state at the time of idling stop, and the engine is started immediately.

  As shown in FIG. 2, the regenerator heat exchanger 5 includes a plurality of flat hollow regenerator tubes 17 enclosing a regenerator material arranged in parallel with each other at regular intervals, and the upper and lower surfaces of each regenerator tube 17. Are joined to hollow pipe-like fixing members 18a, 18b each holding both ends of each cold storage material tube 17 fixedly. The inside of both ends of each cold storage material tube 17 and the inside of the fixing members 18a and 18b communicate with each other. Further, the fixing members 18a and 18b are provided with openings (not shown) used when the regenerator material is filled in each regenerator material tube 17, and the openings are sealed after the regenerator material is filled. Yes.

  Corrugated fins 19 bent into a wave shape are joined between both sides of each cold storage material tube 17. The cold storage material tube 17, the fixing members 18a and 18b, and the corrugated fins 19 are preferably formed from a thin aluminum material in consideration of heat transfer, weight reduction, and the like. In FIG. 2, only a part of the corrugated fins 19 is illustrated, but actually, the corrugated fins 19 are installed in the entire area between both sides of each cold storage material tube 17.

  The regenerator material enclosed in the regenerator tube 17 is brought into a liquid phase state by cooling with, for example, about 3 to 5 ° C. cold air (air) that has passed through the evaporator 4 during normal air conditioning control in which a compressor (not shown) is driven. Phase change to solid phase and solidify, allowing cold storage in the form of latent heat of melting. When idling is stopped (when the compressor (not shown) is stopped), the cold heat is stored using the latent heat associated with melting. The air passing through the exchanger 5 is cooled. As the regenerator material, for example, a regenerator material whose main component is polyalkylene glycol, which causes a phase change at about 10 ° C. and has a latent heat of fusion of about 100 kJ / kg (120 J / cc) or more, can be suitably used.

  In the vicinity of the air outlet downstream of the evaporator 4 in the air flow direction (the narrow space between the evaporator 4 and the regenerator heat exchanger 5), the temperature of the air immediately after passing through the evaporator 4 (hereinafter referred to as the evaporator blowing temperature) is measured. The temperature of the air immediately after passing through the regenerator heat exchanger 5 (hereinafter referred to as the regenerator heat exchanger blowout) is located near the air outlet downstream of the regenerator heat exchanger 5 in the air flow direction. A second temperature sensor 21 for measuring “temperature” is arranged. The temperature information measured by the first and second temperature sensors 20 and 21 is input to the air conditioning control unit (air conditioner ECU) 22.

  The air conditioning control unit 22 includes temperature information input from the first and second temperature sensors 20 and 21, temperature information input from a well-known temperature sensor group (not shown) that detects vehicle interior temperature, outside air temperature, and the like, Based on air-conditioning setting information (air volume, set temperature, etc.) input by the switch operation of an air-conditioning panel (not shown) by the passenger, normal vehicle interior air-conditioning control when the engine is driven and vehicle interior air-conditioning control when idling is stopped (Details will be described later).

(Normal cabin air conditioning control when the engine is driven)
When an occupant operates a switch on an air conditioning panel (not shown) and operates in, for example, the “cooling mode”, the fan motor M is driven to rotate based on a signal output from the air conditioning control unit 22 and the blower fan 3 is rotated, for example, air (inside air) is introduced into the evaporator 4 from the inside air introduction port 9a. Further, by rotating the compressor (not shown) by driving the engine to operate the above-described refrigeration cycle, the air passing through the evaporator 4 exchanges heat with the refrigerant circulating in the refrigerant tube (not shown). And cooled to a predetermined temperature.

  At this time, when the cooled air passes through the regenerator heat exchanger 5, the regenerator material cools the regenerator material in the regenerator tube 17 so that the regenerator material is brought into the solid phase from the liquid phase state in about 1 minute 30 seconds, for example. It changes into a state and solidifies, and cold storage is performed in the form of latent heat of fusion.

  Then, the air conditioning control unit 22 is based on the evaporator blowing temperature information input from the first temperature sensor 20, the air conditioning setting information (air volume, set temperature, etc.) input by the occupant's switch operation, and the like. (Not shown) is controlled to adjust the opening of the air mix door 7. Thereby, a part of the cold air (air) that has passed through the evaporator 4 and the regenerator heat exchanger 5 is introduced to the heater core 6 side, and the cold air and the hot air obtained by the heater core 6 are mixed in the air mix chamber 10. Thus, the air (cold air) whose temperature is adjusted to a desired temperature is blown out from the vent outlet 13 by, for example, turning the vent door 14 to the open position.

(Vehicle interior air conditioning control when idling stops)
When cold air is blown into the vehicle compartment by the refrigeration cycle by the above-described normal vehicle interior air conditioning control, if idling is stopped when the vehicle is stopped, such as waiting for a signal, cold air is generated by the evaporator 4 when the compressor (not shown) is stopped. The air that is no longer generated and whose temperature has risen is introduced into the cold storage heat exchanger 5 by the rotation of the blower fan 3.

  At this time, the cool storage material in the cool storage material tube 17 is phase-changed from the liquid phase state to the solid phase state and stored in the form of latent heat of fusion as described above. Therefore, when the air whose temperature has increased passes through the vicinity of the corrugated fins 19 on both sides of each regenerator material tube 17, the air whose temperature has increased is cooled by using latent heat associated with melting of the regenerator material, and cold air is generated. . And like usual time, a part of cold air produced | generated by the cool storage heat exchanger 5 is introduce | transduced to the heater core 6 side, and the said cold air and the warm air obtained by the heater core 6 are mixed in the air mix chamber 10. FIG. Thus, the air (cold air) whose temperature is adjusted to a desired temperature is blown out from the vent outlet 13 by, for example, turning the vent door 14 to the open position.

  Based on the cold storage heat exchanger blowing temperature information inputted from the second temperature sensor 21, the air conditioning control unit 22 blows out the cold air having the same temperature as the cold air blowing before idling stop. A drive part (not shown) is controlled and the opening degree of the air mix door 7 is adjusted. In this embodiment, the cold storage material melts in about 1 minute and 30 seconds, so that cold air at a desired temperature can be obtained at the time of idling stop such as waiting for a signal of about 30 seconds to 1 minute. Can be blown into the passenger compartment without causing the passengers to feel uncomfortable.

In addition, the said insertion port is formed in the approximate center part vicinity of the air exit surface 5a, for example. Thus, the first temperature sensor 20 connected to the distal end side of the connecting member 31 is positioned between the evaporator 4 and the cold storage heat exchanger 5 at the center near the air outlet surface 4a of the evaporator 4, and the second temperature sensor 21. Is located in the center of the regenerator heat exchanger 5 in the vicinity of the air outlet surface 5a.

  As described above, the first and second temperature sensors 20 and 21 are fixed to the sensor fixing member 30 to form one unit, so that the connecting member 31 connected to the tip of the first temperature sensor 20 is connected to the regenerative heat exchanger 5. The first temperature sensor 20 is placed in the vicinity of the air outlet surface 4a of the evaporator 4 at the second temperature only by fixing the sensor fixing member 30 to the air outlet surface 5a of the regenerator heat exchanger 5. The sensor 21 can be simultaneously installed in the vicinity of the air outlet surface 5a of the cold storage heat exchanger 5. Therefore, it is possible to improve the mounting workability of the first and second temperature sensors 20, 21.

  Further, since it is not necessary to fix a sensor fixing member for fixing the temperature sensor to the air outlet surface 4a of the evaporator 4 as in the prior art, the interval between the evaporator 4 and the regenerator heat exchanger 5 can be reduced. it can. Thereby, the length of the air-conditioning case 2 is shortened, and the whole air-conditioner can be reduced in size (compact).
