Description

[Detailed description of the invention] (Industrial application field) The present invention relates to a dehumidifying air conditioning device for a dehumidifier.

(Prior art) Conventionally, in a dehumidifier that obtains dehumidified air through an evaporator and a condenser, the outside air that passes through the evaporator is converted into cooling air, and this converted cooling air passes through the condenser as it is. This dehumidifier converts cooling air into low-humidity heated air, and does not have a device to adjust the volume of this cooling air that passes through the condenser.

(Problem to be Solved by the Invention) The outside air sucked into the dehumidifier passes through the evaporator of this dehumidifier and is converted into cooling air, and this converted cooling air passes through the condenser as it is. For example, when this dehumidifier is used in a grain dryer, the grains are dried by the dehumidified air generated by the dehumidifier.

When changing the temperature of the dehumidified air generated by this dehumidifier, the temperature of the dehumidified air is controlled by switching the refrigerant to an external auxiliary condenser, but this method requires two condensers. Therefore, it is intended to create a configuration that can obtain low-humidity air at a low cost.

(Means for Solving the Problems) The present invention provides a dehumidifier that obtains dehumidified air through an evaporator 1 and a condenser 2, in which air passes through the condenser 2 between the evaporator 1 and the condenser 2. The structure of the dehumidifying air regulating device is characterized in that a rotatable air volume regulating valve 3 is provided to control the quantity of cooling air.

(Operation of the invention) The outside air sucked into the dehumidifier is converted into cooling air by passing over the evaporator of this dehumidifier, and this converted cooling air directly passes through the condenser 2 to reduce the Humidity is converted into heated air.

When converting this low-humidity heated air into low-temperature, low-humidity air,
By operating the air volume control valve 3 provided between the evaporator 1 and the condenser 2, the dehumidified air generated from the cooling air fan for the condenser 2 becomes low-temperature, low-humidity air.

(Effects of the Invention) According to the present invention, by providing the air volume control valve 3 that switches the cooling air that has passed through the evaporator 1 and been converted into cooling air so as not to pass through the condenser 2, simple operation and At the same time, it becomes possible to obtain low-temperature, low-humidity air with the configuration.
Furthermore, two condensers 2 are no longer required, and the cost is therefore reduced.

(Example) Note that the dehumidifier 5 attached to the grain dryer 4 will be described for rotation.

An operating device 22 for starting and stopping the dehumidifier 5 and the dryer 4 is attached to the front of the dryer 4.
The grains are flowing down from the storage chamber 6 in the upper part to the drying chamber 7 in the lower part. By suctioning and exhausting air to the outside of the machine by the wind machine 10, the upper and lower transfer spirals 11, 1
2. The grains, which are repeatedly circulated by the feed valve 13, grain raising machine 14, etc., are dried by being exposed to the dehumidified air.

The dehumidifier 5 has a box shape, and the front wall plate of the box body is provided with an inlet 15 for sucking outside air, and the rear wall plate is provided with an inlet 15 for sucking outside air into the dehumidifier 5. This configuration is provided with an air outlet 16 for blowing dehumidified air from the octopus into the air blowing chamber 8.

In order to convert the outside air sucked into the dehumidifier 5 from the suction port 5 into dehumidified air, the low-temperature, low-pressure gas that is the refrigerant is adiabatically compressed into high-temperature, high-pressure gas by the compressor 17 and passes through the condenser 2. At the same time, heat is removed and the liquid changes to a high-temperature, high-pressure liquid.Then, the pressure is lowered to a low-temperature, low-pressure liquid at the expansion valve 18, and as it passes through the evaporator 1, it absorbs heat and changes to a low-temperature, low-pressure gas. This cycle is repeated, thereby dehumidifying the outside air passing through the dehumidifier 5 and turning it into dehumidified air.

The compressor 17 is provided in the upper part of the dehumidifier S, the expansion valve 18 is provided in the lower part, and the evaporator 1 is provided in the front part,
The condenser 2 is provided at the rear, and a semicircular air volume control valve 3 is fixed to an air volume adjustment shaft 19 between the evaporator and the condenser 2, and the air volume is controlled by The adjustment shaft 19 is rotatably supported, and one end is L-shaped, and by adjusting the rotation so that the air volume adjustment valve 3 is in a downward position, the airflow can pass through the evaporator 1. This cooling air, which has been converted into cooling air, does not pass through the condenser 2, and by adjusting the rotation of the air volume control valve 3 so that it is in the front-rear direction, this is different from the above. On the contrary, the configuration is such that cooling air passes through the condenser 2 and is converted into heated air, and the rotation of the air volume control valve 3 is manually controlled.
Automatic rotation control may also be used.

Note that the outside air sucked into the dehumidifier 5 is transferred to the evaporator 1.
As it passes through the air, the moisture in the air is cooled and condenses into low-temperature, low-humidity air with reduced absolute humidity.
The structure is such that it absorbs heat as it passes through the air, producing low dehumidified air with a temperature slightly higher than room temperature.

The compressor 17 is rotatably driven by a compressor motor 20, and a heater 21 for auxiliary heating of the dehumidified air is provided in front of the air outlet 16.

Hereinafter, the operation of the above embodiment will be explained.

By operating the operating device 22, each part of the grain dryer 4 and the dehumidifier 5 are started, and the outside air sucked in from the inlet 15 of the dehumidifier 5 passes through the evaporator 1 and the condenser 2. As a result, the heated air with low humidity is converted into dehumidified air, and this dehumidified air is passed from the air outlet 16 through the air blowing chamber 8, through the drying chamber 7, through the air exhaust chamber 9, and then sucked and exhausted by the air exhaust fan 10. As a result, the grains stored in the storage chamber 6 are exposed to the dehumidified air and dried while flowing down from the storage chamber 6 into the drying chamber 7, and are fed out to the lower part by the feeding valve 13 and flowed down. The grain is transferred and supplied into the grain hoisting machine 4 by the lower transfer spiral 12, and the grain hoisting machine 14
It is conveyed to the upper part by the upper transfer spiral 11, supplied and returned to the storage chamber 6, and when it is circulated and dried to reach the finishing target moisture content, it is automatically controlled by the operation bag rP122 and transferred to the dryer 4.
will automatically stop and drying of the grains will be stopped.

When converting this low-humidity heated dehumidifying air into low-temperature, low-humidity dehumidifying air for drying, manually operate the air volume control valve shaft 9 and turn the air volume control valve 3 to the vertical position. The outside air becomes humid air in the evaporator 1, and this low-temperature, low-humidity dehumidifying air is used to dehumidify the evaporator. Enlarged side view, 2nd
