Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an air conditioning system,

The present invention relates to an air conditioning system having a cooling / heating unit or a blower, and more particularly, to an air conditioning system having a cooling / heating unit or a blower, The present invention relates to an air conditioning system in which control is performed.

Generally, in a house or a building that does not have air-conditioning facilities, each room is equipped with an air-conditioner. In this case, not only the installation cost of the air conditioner increases but also the electric energy is used a lot and the electric cost is excessively borne. Therefore, when two air-conditioning units are controlled by one cooling / heating unit, the operation cost can be reduced. However, a separate duct structure and a distribution structure must be provided, and means for switching the air-conditioning direction to the distribution position is required. At this time, pressure fluctuation occurs when adjusting the wind direction, and if the load side receives a load, it may cause failure of the air conditioner. In addition, if the pressure fluctuation occurs when the wind direction is controlled, noise is generated.

As a background of the present invention, Korean Unexamined Patent Application Publication No. 10-2006-0086761 (combined air-conditioning system) is provided with a compressor for compressing a refrigerant and a high-temperature and high-pressure refrigerant compressed in the compressor in a cooling operation mode The outdoor heat exchanger is used as a condenser for condensing the refrigerant at medium temperature and high pressure and is used as an evaporator for evaporating the refrigerant into a low temperature and low pressure gas in the heating operation mode and an evaporator for evaporating the refrigerant to a low temperature and low pressure gas in the cooling operation mode An indoor heat exchanger which is used as a condenser for condensing the refrigerant of high temperature and high pressure compressed by the compressor in the heating operation mode into a refrigerant of middle temperature and high pressure, and an expansion mechanism installed between the outdoor heat exchanger and the indoor heat exchanger to swell the refrigerant , And the outdoor heat exchanger In sikidoe variably rotated at an outdoor ventilation fan, and the blower fan for forcibly blowing air above the heating operation mode comprises the fan driving unit for rotating in a more reduced rotation speed in the cooling operation mode.

Therefore, it is advantageous to improve the cooling / heating performance coefficient (COP) in the heating operation mode by controlling the rotation speed of the outdoor air blowing fan in the cooling operation mode and the heating operation mode to be different.

However, the above-mentioned background art provides a technique of controlling the rotational speed of the outdoor blowing fan according to the cooling and heating, but does not disclose an air conditioning technique capable of selectively cooling and heating two or more rooms.

As another background art of the present invention, Korean Patent Registration No. 10-0888964 (air conditioning system and control method thereof) is an air conditioning system used as an air conditioning system of a building. The air conditioning system includes an indoor heat exchanger, At least one air conditioning unit for selectively performing ventilation, air purification, and cooling / heating of the indoor space by discharging the outdoor air into the room, sucking the outdoor air, and discharging the room air through the heat exchanger; And a capacity variable compression means connected to the indoor heat exchanger for varying the capacity of the heat supplied to the indoor heat exchanger or the capacity of the heat recovered by the heat exchanger to enable the cooling / heating capacity of the air conditioning unit to be varied And at least one outdoor unit.

Therefore, this background technology continuously changes the capacity of the cooling and heating in response to the continuous change of the heating and cooling load in the area where the heating and cooling in the building is required, thereby making it possible to optimally cope with the air conditioning demand, . However, the latter background technology has no technical means to control two rooms with one cooling and heating system, and there is no alternative to reduce load due to pressure fluctuation when selecting the wind direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings, but the present invention is not limited thereto.

As shown in FIG. 1, a cooling / heating unit 10 for selectively supplying cold and warm air is provided. The cooling / heating unit 10 is not limited to a particular type or type, and can be applied to, for example, a single-family house, a building, a factory, and the like.

A discharge direction switching air conditioning switch 20 for switching the air supply direction of the cold air or warm air to the first air supply mechanism 31 or the second air supply mechanism 32 is connected to the outlet of the air conditioner 10.

The air conditioning switch 20 for the air supply direction switching includes a housing for air supply distribution 22, a housing cover 24 for installing a drum, a wind direction adjusting drum 26 and a drive motor M.

The air supply distribution housing (22) is cylindrical in which the lower part is closed and the upper part is opened. The air supply and distribution housing 22 is provided with one inlet port 22a on its outer circumferential surface and a plurality of outlet ports 22b and 22c spaced from the inlet port 22a by a predetermined angle. In the present embodiment, the outlet ports 22b and 22c are arranged at positions spaced 90 degrees from the inlet port 22a circumferentially.

The first supply mechanism 31 and the second supply mechanism 32, which are connected to each other through the supply ducts 5 and 7, are connected to the housing for power distribution and distribution. The first-level equipment (31) and the second-level equipment (32) can be installed in different rooms.

The housing cover 24 for drum installation is used to install the drum 26 for controlling the airflow inside the housing for air supply and distribution. The housing cover 24 for drum installation is detachably coupled to the upper portion of the housing for power supply distribution 22. The housing cover 24 for drum installation can be screwed to the housing for power supply distribution 22 as in the present embodiment. However, the drum-mounting housing cover 24 may also be coupled to the upper portion of the power distribution housing 22 using hook type jaws or mounted on the upper portion of the power distribution housing 22 through the link-type lock lever . At this time, a separate sealing material (or rubber packing) may be further provided to maintain the airtightness at the joint surface between the housing cover 24 for the drum installation and the housing 22 for the air supply distribution.

The wind direction adjustment drum 26 is formed in a cylindrical shape smaller than the housing for power supply and distribution. At this time, the diameter of the outer circumferential surface of the wind direction adjusting drum 26 is configured to be equal to the inner circumferential diameter of the housing for power supply distribution 22. At this time, the wind direction adjusting drum 26 is assembled to the supply / distribution housing 22 with an assembly tolerance. Preferably, the outer circumferential surface of the wind direction adjusting drum 26 is provided so as to provide a sliding contact surface with the inner circumferential surface of the housing 22 for supplying and distributing power. The wind direction adjusting drum 26 is installed inside the housing 22 for distributing the oil, which opens the housing cover 24 for installing the drum. Therefore, the wind direction adjustment drum 26 is disposed in the same rotation axis Z as the housing for power supply and distribution 22, so that it is rotatably installed inside the housing for power distribution.

The wind direction adjusting drum 26 has a first rear port 26a corresponding to the inlet port 22a and a second rear port 26b corresponding to one of the outlet ports 22b and 22c, . In the present embodiment, since the outlet ports 22b and 22c and the inlet port 22a are spaced at intervals of 90 degrees on the circumference, the first rear port 26a and the second rear port 26b also have the same circumferential 90 degree intervals.

6A, the wind direction adjusting drum 26 is divided into a first non-load section 261b consisting of an opening 261b distributed or punctured as a pore 261a between the first back port 26a and the second back port 26b, And a second no-load section including another opening 262b, which is distributed or cut away from the second rear port 26b by a different perforation 262a, as shown in FIG. 7b.

Thus, since the first and second no-load sections are included in the wind direction adjusting drum 26, the outside air flowing into the inlet port 22a is continuously distributed to the perforations 261a without any interruption, And is discharged through the one outlet port 22b immediately before closing and the other outlet port 22c opened through the other opening 262b distributed through the other hole 262a through the cutout opening 261b, So that no load is generated on the inside and outside of the inlet port 22a without a pressure difference, so that no moving load is given to the air conditioner 10.

In addition, the present invention can be easily installed in the housing (22) for distributing wind by applying the detachable drum cover (24) for housing the wind direction, and when the housing cover (24) for installing the drum is removed, It is possible to further facilitate the maintenance and management of the inside of the charging housing 22 and the foreign matters of the wind direction adjusting drum 26. Also, the housing for supplying and distributing the power 22 and the wind direction adjusting drum 26 are formed in a cylindrical shape, so that the structure is simple and easy to manufacture, and the assembly and installation between them are facilitated.

The drive motor M controls the rotational direction and the position of the air volume adjusting drum 26. The drive motor M is fixed by bolts to the housing for power supply distribution 22. The output shaft (drive shaft) of the drive motor M is inserted and coupled to a boss 26c protruding inwardly at the center of rotation of the air volume adjusting drum 26 through a housing 22 for supplying air supply and distribution. At this time, the output shaft of the driving motor M is connected to the boss 26c through a key coupling to transmit the rotational force to the wind direction adjusting drum 26. The drive motor M may be a geared motor including a general motor, a reduction gear, and a stepping motor capable of controlling the angle and speed.

The controller 100 is electrically connected to the drive motor M of the air-discharge direction switching switch 20 as shown in Fig. The controller 100 controls the rotational direction and the rotational amount of the air amount adjusting drum 26 to control the air supply direction and the air supply amount. Further, the controller 100 has a display unit for displaying the temperature of the supply air area. Accordingly, the controller 100 is connected to the indoor sensors S 1 and S 2 at the positions where the first and second classifiers 31 and 32 are installed. Therefore, the controller 100 compares the temperatures T1 and T2 measured by the temperature sensors S1 and S2 with the set temperature T and controls the driving motor of the air-discharge direction switching air- (M). The controller 100 includes a power operation switch 101, an operation lamp 102, a thermometer 103, a temperature setting change switch 104, a temperature display 105, and a room selection button 106.

The operation and operation of the air conditioning system in which the direction of the air supply without fluctuation of the pressure load thus constructed is adjusted will be described with reference to the flow chart of FIG.

7, the controller 100 measures the temperature detected by the temperature sensors S1 and S2 of the respective rooms R1 and R2 (S10), and determines the set temperature T (S11). The set temperature T is the temperature set in the room R where the cooling / heating unit 10 is installed.

For example, when the measured temperature T1 of the first room R1 is measured to be higher than the set temperature T, the driving motor M is driven by the controller 100, And communicates the inlet port 22a of the housing 22 for the air-conditioner distribution to the first room-side outlet port 22b.

Accordingly, the cool air discharged from the cooling / heating unit 10 is supplied to the first room R1 through the first supply mechanism () to be cooled (S12).

Thereafter, when the measured temperature T1 of the first room R1 is measured to be lower than the set temperature T, it is determined whether or not the measured temperature T2 of the second room R2 is higher than the set temperature T S13).

When it is determined that the measured temperature T2 is higher than the preset temperature T, the controller 100 drives and controls the driving motor M to change the direction of the air volume adjusting drum 26 connected thereto (S14) The inlet port 22a of the charging housing 22 is communicated with the second room side outlet port 22c and the first room side outlet port 22b is closed.

Accordingly, the supply of cold air to the first room R1 is interrupted and the cooling is interrupted, and the supply of cold air to the second room R2 is continued so that the cooling (S15) of the second room R2 proceeds.

If it is determined that the measured temperature T2 is lower than the set temperature T, it is determined whether the measured temperatures T1 and T2 of the rooms R1 and R2 have reached the set temperature T (S16). If the measured temperatures T1 and T2 of the rooms R1 and R2 do not reach the preset temperature T, the temperature of each of the rooms R1 and R2 is measured again. When the measured temperatures T1 and T2 of the rooms R1 and R2 reach the set temperature T, the coolant bagger 10 stops operating (S17).

In the case of the heating mode of the cooling / heating unit 10, since the heating unit according to the control flow is supplied instead of the cooling unit, detailed description thereof will be omitted.

As described above, the air conditioning system according to the present invention is provided with the air conditioning switch 20 for changing the direction of air supply so that the selection and direction of the air supply can be easily controlled and there is no pressure difference between the air conditioner side and the air supply direction switching part, There is no work.

In addition, the present invention is economical because it is possible to control the room temperature of two rooms with one cooling / heating unit.

Therefore, this air conditioning system can be applied not only to houses, buildings, factories, but also to underground facilities such as subways.

In the meantime, although the present air conditioning system is applied to the air conditioner 10, it is needless to say that the same configuration can be applied to the blower 12 as shown in FIG. 2 in place of the air conditioner 10.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is evident that many alternatives, modifications and variations will be apparent to those skilled in the art in light of the above teachings. will be. The invention is not limited by these variations and modifications, but is limited only by the claims appended hereto.
