(Prior Art) A vehicle air conditioner is a combination of a heating device that uses heat from engine cooling water and a cooling device that compresses refrigerant using a compressor driven by the engine's crankshaft. When using this air conditioner,
Switching between the heating side and the cooling side is performed by operating a lever provided on the instrument panel. Regardless of whether it is summer or winter, a vehicle user turns on the air conditioner if there is a temperature difference between the current interior temperature of the vehicle and a desired set temperature. When the switch is turned on, the heating or cooling function (sometimes both at the same time) will operate, bringing the temperature inside the vehicle closer to the desired set temperature. In this case, in order to bring the vehicle interior temperature to the desired set temperature more quickly, the air volume of the blower for blowing out the heat-exchanged air into the vehicle interior may be controlled. This air volume control increases the air volume when there is a large difference between the current vehicle interior temperature and the desired set temperature. Therefore, in this case, the maximum air volume will continue for a long time, causing discomfort due to noise.

(Problem to be Solved by the Invention) A prior art invented to solve this problem is described in Japanese Patent Application Laid-open No. 12330/1983. The device in this publication reduces the air volume when a predetermined time has elapsed since startup. However, since the invention disclosed in this publication reduces the air volume over time, there is a problem in that when the temperature is not close to the desired set temperature even after time has elapsed since startup, the cooling capacity decreases due to insufficient air volume. The present invention has been made with the aim of solving this problem.

(Means for solving the problem) As a means for solving this problem, the present invention provides a vehicle air conditioner that adjusts the temperature difference between the current vehicle interior temperature and the desired set temperature and the air volume of the blower. It is configured to change the relationship into multiple types.

(Function) With this configuration, the air volume can be changed according to the temperature difference between the current vehicle interior temperature and the desired set temperature (hereinafter referred to as the difference temperature), so the difference temperature can be changed. When a certain value is reached, the air volume can be made smaller than the standard value. As a result, discomfort due to noise will not occur. When the temperature difference becomes small to a certain extent, the subsequent temperature change is not so influenced by the air volume, so there is no functional problem even if the temperature is controlled in this way.

Next, a method for controlling air volume of an air conditioner according to the present invention will be explained. Generally, when the temperature difference is large, the air conditioner maximizes the air volume to reach the target temperature in as short a time as possible. This is the same on both the heating side and the cooling side. However, on the heating side, the air (warm air) outlet inside the vehicle is at the passenger's feet, and even if there is a large amount of air, the noise is not so much of a concern, whereas in the case of air conditioning, air (cold air) is Since the outlet of the ventilator is directed toward the chest of the passenger, if there is a large amount of air blown out, the noise will be a concern.

This can also be done for a short time, but if the difference in temperature is large, some means must be taken to solve the problem. Therefore, in the present invention, the control amplifier 1 is provided with a function to change the relationship between the temperature difference and the blower air volume into multiple types, and is particularly useful during cooling when a large air volume causes noise. It is controlled differently from when heating.

Figure 2 shows this relationship, and shows the heating range (A to F
) and the cooling range (A-D), the air volume is originally adjusted at the same rate of change, but it is changed on the cooling side. In other words, with respect to the solid line between A to F on the heating side, a rate of change in the range C on the cooling side is set to be slower than the standard rate of change shown by the broken line. This is because the air volume is initially increased to make the temperature difference zero, and when the temperature difference reaches a certain temperature, the rate of change in air volume is reduced. This control can be easily performed using a microcomputer installed in the control amplifier l.

To further explain FIGS. 3 to 7, FIG. 3 shows the relationship between temperature difference and air volume. In this figure, ■ indicates that the characteristics of the difference temperature and air volume on the cooling side are the same as those of the heating side, and ■ indicates that the characteristics are gentle. FIG. 4 shows the general relationship between indoor temperature and time during cool-down. If the air volume is controlled based on the condition (■) in FIG. 3, the result will be as shown in FIG. 5, and the time for the maximum air volume (MAX Hi) will become longer, causing discomfort as described above. Therefore, if you do as shown in Figure 3 (■), the intermediate air flow time will be longer, and it will take more time to cool down. In general, in a cool-down test, when the initial temperature is 30°C or higher, the inventors have confirmed that the temperature drops rapidly to 30°C and then gradually decreases. It is best to use a large air volume to rapidly lower the temperature until the temperature has dropped to a certain extent, and then lower the temperature gradually.

If the set temperature is 20°C to 25°C to 30°C, the set temperature inside the control amplifier 1 will be 18°C to 23°C to 28°C when there is sunlight. Therefore, in order to reduce the noise of the blower, the temperature inside the vehicle should be adjusted to 30°C to 4°C.
When the temperature drops to 0°C, the air volume will be slightly lowered. However, if the temperature is allowed to drop gradually to the set temperature from the beginning as shown in ■ in Figure 3, the cooling capacity will decrease due to insufficient air volume, so if the difference in temperature is large as shown in Figure 7, the air volume will be Lower the temperature gradually, and then lower it rapidly when the temperature difference becomes small. FIG. 8 shows actual data controlled in this manner.

(Effect of the invention) Since the present invention is configured as explained above,
It is possible to control the air volume based on the bodily sensation of vehicle occupants.
There is no discomfort caused by noise as in the conventional case. Then, the relational expression between the difference temperature and the air volume is changed between heating and cooling when the air blowing position is different. Compatibility with many car models is a must.
