A system and a method of providing the same.

In general, a bus air conditioner is a device mounted on a roof of a bus to cool an internal space of a bus, and a condensation chamber is provided at one side to form a liquid refrigerant by heat-exchanging compressed high-temperature / high-pressure refrigerant gas with external air. Condenser is built in

In addition, an evaporation chamber is provided on the opposite side of the condensation chamber, and an evaporator is provided inside the evaporation chamber to evaporate a refrigerant liquefied through the condenser to exchange heat with air in the room.

The bus air conditioner is mounted so that the condensing chamber faces forward, and a condenser for liquefying refrigerant gas in the center is provided to divide the condensing chamber from side to side by a separate frame. In addition, a plurality of condensation fans forcibly supplying air to the condenser is mounted on the upper part of the condenser, and a plurality of condensation fans are connected to the upper frame. It is provided.

And, both sides of the upper cover is provided with a side door to open and close the condensation chamber up and down, the side door is formed with a plurality of side inlets so that air can be introduced by the condensation fan. Thus, the condenser is cooled by the outside air introduced through the side inlets.

In the evaporation chamber, an outside air inlet is formed at the center of the roof of the evaporation chamber so as to face each other, and an air induction plate is installed between the indoor air intake port and the outside air intake port, and both air induction passages of the air induction plate and the evaporator are provided. Internal and external air switching dampers are provided in between.

Therefore, by adjusting the internal and external air switching damper to vent the outside air into the indoor space to ventilate the internal space of the bus.

In general, the air conditioner of the bus can be classified into air conditioners, heaters, and ventilators. Among them, an electric ventilator having its own fan and motor and an emergency exit door that can be opened or closed manually or electrically Manual and electric fans, which are installed on the ceiling, are mainly used.

The air conditioner of the bus is largely classified from a passenger car, because the air conditioner, the heater, and the ventilator, which are the air conditioner of the bus, are separately installed and operated separately.

In other words, the passenger car is concentrated in the HVAC (Heating, Ventilating, and Air-Conditioning) system in the center of the instrument panel, and the control can be integrated and made easy to use.

In contrast, the bus is equipped with a separate air conditioner and a ventilation device, and provided with each control device, which is inconvenient for the driver to use and has a limitation in providing a comfortable air conditioning environment for the passengers.

The refrigerant is transferred to a condenser to be described below to convert the liquid refrigerant into the liquid refrigerant in the condenser, and the liquid refrigerant is reduced to a low temperature low pressure liquid refrigerant through an expansion valve.

In addition, the liquid refrigerant converted as described above is supplied to an evaporator, thereby cooling the air by transferring heat from outside air or inside the bus.

Air cooled in this way is discharged back into the bus through the blower fan to harmonize the inner space of the bus comfortably, and the heat exchanged refrigerant is transferred to the compressor to compress and condense to cool the inner space of the bus as described above. The cycle of expansion-evaporation is carried out continuously.

On the other hand, of the components forming the circulation cycle as described above except for the compressor is all provided in the interior of the cooling device provided on the roof of the bus.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

FIG. 1 is a general configuration diagram of a cooling system of a bus, and FIG. 2 is a diagram illustrating a configuration of a system for predicting a temperature of a room according to an airflow amount in a duct and controlling a cooling air supply accordingly.

Conventionally, a method of adjusting the total air volume by measuring the air volume in the duct, predicting whether the air volume control device is opened or closed for each seat position has been used.

As shown in FIG. 2, an air circulation structure of a roof-on type bus air conditioner is shown, and an air conditioner main body having a blower 111 and a heat exchanger 112 is installed in a roof of the bus. And, along the left and right longitudinal direction of the room is provided with a duct 114 in which the airflow amount adjusting device is mounted for each seat position.

In the existing air conditioner structure, an ammeter A capable of detecting a load (current) of the blower 111 is installed so that the load value (current value) according to the operation of each control stage of the blower 111 is controlled by the controller 100. To be provided to the side.

In a predetermined position inside the duct 114, which is a passage through which cooled cool air is moved, for example, a position at which the air conditioner main body and the duct 114 are connected, the pressure in the duct 114 changed according to the flow resistance of the air is changed. A differential pressure sensor 113, which is a kind of pressure gauge that can be detected, is installed so that a pressure value (voltage value) in the duct 114 is provided to the controller 100 side.

The controller 100 is programmed with a mapping graph corresponding to the reference current value of the blower and the reference differential pressure value in the duct for each control stage of the blower 111, as shown in FIG. By using this as a reference value, a control signal such as maintaining or lowering the control stage of the blower 111 can be output after comparing the detected value input from the ammeter and the differential pressure sensor 113.

If the room is hot, the air flow control device of each seat is opened by the passenger's operation, the air flow resistance in the duct decreases, the blower load (current amount) decreases, and the differential pressure due to the flow rate increases.

When the room is cold, the air flow control device of each seat is closed by the passenger's operation, the air flow resistance in the duct increases, the blower load (current amount) increases, and the differential pressure due to the flow decreases.

Therefore, the controller controls the control stage of the blower from the current stage to the low stage, or decreases the load of the blower when the load increase and the differential pressure of the blower are reduced by comparing the mapped value, that is, the reference value and the input detection value. If the differential pressure increases, the control stage of the blower is maintained at the current stage.

However, this method has a disadvantage in that it is not possible to recognize the exact situation because it only detects the amount of air flow in the duct and predicts opening / closing of the air volume control device for each seat. Therefore, the present invention proposes a technique for attaching a sensor for measuring the opening or closing of the air flow control device for each seat, and receives a signal from the seat, and accurately controls the air flow of the entire system according to the number of open air flow control device. .

The air conditioner is operated and the blower and the heat exchanger are operated, and the process of the cold air is supplied to each seat through the hot air inlet → the temperature drop by the heat exchange → the blower is moved to the duct → the air volume control device.

The working principle of the present invention will be described in more detail as follows. If the room temperature is hot or cold, the passenger's response to the haptic temperature, ie opening or closing the airflow control device, is performed.

When the air flow control device is closed as the passenger feels cold, the air flow resistance in the duct → the flow rate decrease in the duct → the air blower load increases and the differential pressure decreases, and when the air flow control device is opened as the passenger feels hot, Reduction of air flow resistance in the duct → increased flow rate in the duct → reduces the blower load and increases the differential pressure.

When a change in the load value or the differential pressure value appears according to the passenger's response as described above, the corresponding control of the blower is performed after comparing the detected value with the reference value.

This is similar to the technique of adjusting the blowing intensity of the entire system by measuring the blowing amount in the duct described above. That is, the control stage of the blower is similar in that it can be maintained or down adjusted by reflecting the intention of the passenger.

3 to 7 illustrate a configuration diagram of a cooling system control system for a bus considering whether or not to open a vent for each seat according to the present invention.

The necessity of the subject which the present invention was devised is as follows.

The thermostat that maintains the existing specific temperature cannot reflect the taste of people who want different temperatures according to individual preferences in each situation.

In particular, if only one person opens the tuyeres, the remaining tuyeres are closed, so you can receive stronger and colder winds than you want. Furthermore, this can result in energy waste.

In addition, the opening and closing or opening direction of the individual air vents can be adjusted according to the needs of the individual, but the temperature in the total space must follow the centralized cooling system.

Accordingly, the present invention provides a system and a method for controlling the central heating and cooling apparatus by receiving a plurality of temperatures in a total space, and receiving feedback from a sensor of an individual tuyere.

3 to 7, the present invention is a bus cooling system control system for performing hot air cooling divided by seats, a hot air cooling device 20 for supplying air of a set temperature, and the hot air cooling device ( A main duct 21 for transporting air at a temperature set from 20, a plurality of individual ducts 22 branched from the main duct 21, for transporting air at a temperature set for each seat, and the individual ducts 22. Air flow rate control unit (11, 12) for controlling the opening and closing of), the sensor 13 for measuring the opening and closing of the individual duct 22, and opening of the air flow rate adjustment unit (11, 12) from the sensor (13) It is characterized in that it comprises a control unit 30 for receiving the received number, on the basis of this determines the operating level of the warm air conditioner (20).

In this case, the sensor 13 is provided so as to measure the open areas of the airflow control units 11 and 12, and the control unit 30 opens the airflow control units 11 and 12 from the sensor 13. It is characterized in that it comprises a control unit 30 receives the area, and determines the operation level of the warm air conditioner 20 based on the total open area.

In particular, the controller 30 increases the operating level of the warm air conditioner 20 when the number of the open increases, and decreases the operating level of the warm air conditioner 20 when the open number decreases. It is characterized by.

FIG. 3 shows a main duct 21 to which air at a temperature set from the hot air conditioner 20 is supplied, and an individual duct 22 branched from the main duct 21 to supply air to the air outlet of each seat. . The end of each duct 22 is provided with an air blowing amount adjusting unit 11 to adjust the amount of air supplied into the vehicle.

FIG. 4 is a view in which a sensor 13 capable of measuring whether the air flow amount adjusting unit 11 is opened is further added to the air flow amount adjusting unit 11. The sensor 13 can measure whether the airflow amount adjusting unit 11 is open or closed, and can measure the open area.

FIG. 5 illustrates an input signal line 31 in which the controller 30 obtains a value measured from the sensor 13 by using wired communication or short-range wireless communication. In addition, the control unit 30 has an output signal line 32 connected to the hot air conditioner 20 so as to control the operation of the hot air conditioner 20.

FIG. 6 shows a state in which a part of the airflow adjusting units 11 and 12 provided in the six individual ducts 22 is opened, for example. This can be distinguished between the open airflow control unit 12 and the closed airflow control unit 11 in the drawings.

Two of the six air flow rate adjusting units 12 are open, and four air volume adjusting units 11 are closed. In this case, since the air conditioner 20 supplies air in accordance with the initial set value, the air is blown harder into two open portions than all six are opened.

In the present invention, through the control unit 20 to adjust the operating level of the warm air conditioner 20 according to the initial situation.

In the present specification, the operation level may be a step for each intensity of air blowing amount of the warm / cooling device 20 or a step for each temperature of air supplied. In general, it is difficult to change the temperature of the air supplied from the warm air conditioner, and it is a general step to control the temperature by adjusting the amount of air introduced into the room, which may be an intensity step of the blowing amount. However, the present invention is not necessarily limited thereto, and it is also possible to change the supply temperature of air.

FIG. 7 illustrates the introduction of the air flow rate sensor 23 to the air flow rate in the main duct 21 according to whether the air flow rate adjusting units 11 and 12 are opened or closed. When measuring the airflow amount through the airflow sensor 23, there is an advantage that can predict the number of open airflow control unit (11, 12) without using the sensor 13, but also has the disadvantage that it is not accurate.

Therefore, the present invention is characterized by maintaining the operating level of the cooling and heating device 20 to always maintain the predetermined air flow rate using the air flow rate sensor (23). The air volume sensor 23 may be an air pressure sensor or the like.
