Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a duct type air conditioner in which the room temperature is controlled by controlling the amount of air flowing into each air-conditioned room.

[0002]

2. Description of the Related Art In recent years, air conditioners have been sought for comfortable air conditioning by varying the air flow rate.

A conventional example will be described below with reference to the drawings. FIG. 13 is a schematic configuration diagram showing an example of a conventional air conditioner. Reference numeral 1 denotes an indoor unit main body, which includes an indoor blower 2 of a rotation speed control type, a blower controller 2a for controlling the rotation speed of the indoor blower 2, and an indoor heat exchanger 3. Reference numeral 4 denotes an outdoor unit body, which includes a compressor 5, an outdoor heat exchanger 6, and an outdoor blower 7 inside. Further, a capacity controller 8 for controlling the rotation speed of the compressor 5 is provided.

A duct 10 is provided from the indoor blower 2 to a branch chamber 9, and from the branch chamber 9 to each of the air-conditioned rooms 11, 12, 13 branch ducts 14, 15, 16 are provided.
Are arranged respectively. Branch ducts 14, 15, 16
Variable air volume units 17, 18, 19
Is installed. Variable air volume unit 17,18,1
Reference numeral 9 is a motor 1 for driving the dampers 17a, 18a, 19a and the dampers 17a, 18a, 19a, respectively.
7b, 18b, 19b and motors 17b, 18b, 19
Air flow rate controllers 17c, 18c, 19c for controlling b are provided.

Further, in the air-conditioned rooms 11, 12, 13 are arranged temperature controllers 20, 21, 22 which also have room temperature setters 20a, 21a, 22a and room temperature detectors 20b, 21b, 22b. It is set up.

A temperature detector 23 and a static pressure detector 24 for detecting the static pressure outside the machine are provided in the branch chamber 9.
Further, a temperature setter 23a and a static pressure setter 24a are provided for setting the set temperature to be constant during cooling and heating respectively.

Next, the operation will be described. Indoor unit body 1
The outdoor unit main body 4 is connected to form a publicly known refrigeration circuit, and hot air or cold air blown out from the indoor unit main body 1 passes through the duct 10 and is branched by the branch chamber 9 before being subjected to each air conditioning. Branch ducts 14 to chambers 11, 12, 13
Guided at 15, 16.

The variable air volume units 17, 18 and 19 provided in the middle of the branch ducts 14, 15 and 16 are
The air volume controller 17c, by the difference between the temperature set by the indoor temperature setters 20a, 21a, 22a in the temperature controllers 20, 21, 22 and the temperature detected by the indoor temperature detectors 20b, 21b, 22b, The motor 17b, 18b, 19b is driven through the dampers 17c, 19c.
The openings a, 18a, 19a are changed to change the passing air volume.

When the air volume changes in the variable air volume units 17, 18 and 19, the external static pressure in the branch chamber 9 changes, and the static pressure detector 24 catches the change and the blower controller 2a external static pressure changes. Is set to a set value by the static pressure setting device 24a, in order not to cause discomfort due to a sudden change in the number of rotations of the indoor blower 2, and to always secure a stable air flow without causing hunting, Within a range of a predetermined amount, a predetermined amount of change is controlled at regular intervals.

Specifically, as shown in Table 1, the frequency of the indoor blower 2 is changed by the difference between the detected static pressure and the set static pressure to control the rotation speed.

[0011]

[Table 1]

Also, the blower controller 2a is
The proper air volume is unknown, and the indoor blower 2 is activated from a predetermined minimum operable rotation speed in order to prevent an excessive air volume at the time of activation.

The variable air volume units 17, 18, 19
The temperature of the branch chamber 9 changes due to the change in the air volume of the indoor blower 2 due to the change of the temperature change. However, the temperature change is detected by the temperature detector 23 and is always constant during operation. The capacity controller 8 controls the number of revolutions of the compressor 5 to set the setting value of. At this time, the compressor 5 is stopped when the temperature falls below the preset value of the temperature setter 23a during the cooling operation or rises during the heating operation.

[0014]

However, in the above-mentioned configuration, at the time of startup, the indoor blower is started from a predetermined minimum number of revolutions, and static pressure detection is performed at regular intervals within a predetermined amount range as in normal control. Since the rotation speed increases by a predetermined amount due to the pressure difference between the static pressure setting device and the static pressure setting device, it takes a long time for the value of the static pressure detection device to reach the value of the static pressure setting device. Since the air volume does not increase, the detected value of the temperature detector drops sharply during cooling, rises during heating, and falls too much above the specified value of the temperature setter during cooling, and rises too much during heating. Therefore, the minimum limit of the capacity control of the compressor is exceeded, the compressor is temporarily stopped, and then the compressor is restarted after a predetermined time elapses.

Thus, although the air-conditioned room must be rapidly cooled or heated at the time of startup, the compressor is unnecessarily stopped at the time of startup.
There is a problem that the air-conditioned room cannot be cooled or heated rapidly. In addition, there is a problem that a cold draft occurs when heating is started because the compressor is temporarily stopped.

The present invention solves the problems of the conventional air conditioners. In a variable air volume type air conditioner,
An air conditioner having a function of preventing a compressor from stopping.

[0017]

In order to achieve this object, in the air conditioner of the present invention, in addition to the conventional case, at startup, until the detection value of the static pressure detector reaches the set value of the static pressure setting device. Is the start mode, and in the start mode, the controller for the blower with start-up correction function that controls the rotation speed of the indoor side blower by the change amount that is larger than the predetermined change amount in the normal mode at regular time intervals. It is equipped with.

In addition to the conventional air conditioner of the present invention, in addition to the conventional case, the start mode is set until the detected value of the static pressure detector reaches the set value of the static pressure setter at start-up. Is equipped with a blower controller with a start-up correction function that controls the rotation speed of the indoor blower at a time earlier than the change time in the normal mode.

In still another air conditioner of the present invention,
In addition to the conventional method, the start mode is set until the detection value of the static pressure detector reaches the set value of the static pressure setting device at start-up. It is equipped with a machine capacity controller.

In still another air conditioner of the present invention,
In addition to the conventional method, the startup mode is set until the detection value of the static pressure detector reaches the set value of the static pressure setting device at startup.In the startup mode, the temperature difference between the temperature detector and the temperature setting device is compressed. It is equipped with a compressor capacity controller with a start-up correction function that keeps the compressor running even if it reaches the stoppage range.

[0021]

Since the air conditioner of the present invention has the above-described structure, the number of rotations of the indoor blower is normally set at the time of startup until the detected value of the static pressure detector reaches the set value of the static pressure setting device. The air flow rate is increased in a short time after startup to change the rotation speed of the indoor blower by changing by a change amount that is a predetermined times larger than the predetermined change amount at the time, and the detected value of the temperature detector rapidly drops during cooling and heating. To prevent rising, exceeding the minimum control of compressor capacity,
It is intended to prevent the compressor from temporarily stopping and to cool or heat the air-conditioned room rapidly at startup. Further, when the compressor is temporarily stopped at the time of heating start, cold draft occurs, but this is prevented and a comfortable rapid heating is realized.

Further, since the air conditioner of the present invention has the above-mentioned structure, at the time of start-up, the rotation speed of the indoor blower until the detected value of the static pressure detector reaches the set value of the static pressure setting device. Controls the rotation speed of the indoor blower faster than the normal change time, so the air volume is increased in a short time after startup, and the detected value of the temperature detector suddenly drops during cooling and rises during heating. It is possible to prevent the compressor from being temporarily stopped by exceeding the minimum control of the capacity of the compressor, and to rapidly cool or heat the air-conditioned room at the time of startup. Further, when the compressor is temporarily stopped at the time of heating start, cold draft occurs, but this is prevented and a comfortable rapid heating is realized.

Still another air conditioner of the present invention has the above-mentioned structure. Therefore, at the time of start-up, the number of rotations of the compressor is increased until the detected value of the static pressure detector reaches the set value of the static pressure setter. Since the compressor is fixedly operated, it is possible to prevent the compressor from once stopping at the time of startup and to rapidly cool or heat the air-conditioned room at the time of startup. Further, when the compressor is temporarily stopped at the time of heating start, cold draft occurs, but this is prevented and a comfortable rapid heating is realized.

Still another air conditioner according to the present invention has the above-mentioned structure. Therefore, at the time of start-up, the temperature detector and the temperature detector are kept until the detected value of the static pressure detector reaches the set value of the static pressure setter. Even if the temperature difference of the setter reaches the stop range of the compressor, the compressor is not stopped and the operation is maintained. It realizes the cooling or heating of the. Further, when the compressor is temporarily stopped at the time of heating start, cold draft occurs, but this is prevented and a comfortable rapid heating is realized.
