DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for deodorizing and removing dust in a hotel guest room, and more particularly to a method for effectively removing odor and dust, among air quality in a hotel guest room.

[0002]

2. Description of the Related Art Guest rooms in hotels are intended to provide a relaxing space for unspecified people. It is difficult to create a relaxing space unless a comfortable indoor environment is secured. Achieving a comfortable indoor environment is achieved at a high level with well-balanced factors related to architectural planning such as space composition and interior finishing, and factors related to facility planning such as thermal environment, indoor air quality, sound, and light. Needs to be done. Among these, there are many complaints especially regarding the thermal environment (temperature, humidity, airflow) and indoor air quality (odor, dust, CO ₂ , and other harmful substances). Can be recognized as an important factor for comfort.

Normally, in office buildings and the like, a circulation system is adopted in which the air blown out from an air conditioner (supply) is recovered by return air (resin), temperature-controlled and humidity-controlled, and then supplied again indoors. It Therefore, dust can be relatively easily removed by providing a dust collecting filter in the air conditioner. On the other hand, in air conditioning in hotels,
As shown in FIG. 4, after the outside air is temperature-controlled and humidity-controlled by the air conditioner 1 and supplied to each guest room, the air in the guest room is directly exhausted to the outside. The ventilation volume at this time is the amount of steam or the like exhausted from the bathroom in a predetermined time, that is, a general one guest room (2
50 to 12 per 0 to 30 m ² , ceiling height of about 2.5 m)
0 m ³ / H was the usual amount.

At this ventilation amount, CO
Regarding the _two concentrations, the acceptable values could be satisfied. On the other hand, dust and odor cannot be sufficiently removed by this ventilation amount, and especially, odor may leave a body odor or cigarette odor until the next day, and the guest room may not be available. In order to solve such a problem, conventionally, for example, a window of a guest room is opened to remove dust and deodorize by natural ventilation, or a fan coil unit 3 provided for each guest room is provided with a dust removing unit 5 and a deodorizing unit 7. The air in the cabin circulated by the blower 9 of the fan coil unit 3 is provided to remove dust and deodorize.

[0005]

However, the blower 9 of the fan coil unit 3 provided for each cabin is
Since the amount of air blown is small, a high-performance dust removal unit and deodorization unit with particularly large pressure loss cannot be installed.
In addition to being unable to perform sufficient dust removal and deodorization, there is a possibility that the performance of the fan coil unit 3 may be deteriorated due to pressure loss. In addition, although the adsorption type deodorizing unit using activated carbon or the like is effective for adsorbing a specific odor, all the odors cannot be removed and a sufficient deodorizing effect cannot be obtained. Furthermore, a dust removal unit,
When the deodorizing unit is disposable or needs to be regularly cleaned, its maintenance is also complicated, and there is a problem that it itself becomes a source of odor when used after the effective period. If the dust removing unit and the deodorizing unit are provided, the initial cost and running cost correspondingly increase.
The present invention has been made in view of the above circumstances, and can reliably remove dust and odor without deteriorating the performance of the fan coil unit, and can be realized at a low initial cost and running cost in a hotel guest room. The purpose is to provide a deodorizing and dust removing method for improving the indoor environment by ensuring good air quality.

[0006]

In order to achieve the above object, the structure of the deodorizing and dust removing method in the hotel guest room according to the present invention is such that the motor dampers of the supply duct and the exhaust duct provided in each guest room are at the center when the guest room is used. When a control signal from the control device opens at a predetermined opening and a signal to that effect is input to the central control device at the end of use of the guest room,
Alternatively, when a signal indicating that cleaning of the passenger compartment is started is input to the central control unit, the central control unit sends a control signal to fully open the motor damper of the corresponding guest room, and fully open the motor damper. Thus, the ventilation amount is set to the maximum, and the dust generated at the time of cleaning by the ventilation and the odor remaining at the end of use of the guest room are exhausted from the inside of the guest room to the outside through the exhaust duct. In this method of deodorizing and removing dust in the guest room, dust and odor are discharged from the exhaust duct due to ventilation, and more reliable dust removal and deodorization can be achieved than when dust is collected from the circulating air by the dust removal unit and deodorization unit. It will be possible. Further, it is not necessary to attach a dust removing unit and a deodorizing unit to the fan coil unit provided in the passenger compartment. Furthermore, all the odors and dust are discharged to the outside and do not remain in the cabin in the state of being collected by the dust removing unit and the deodorizing unit. In addition, the periodic inspection that occurs when the dust removing unit and the deodorizing unit are attached is also unnecessary.

[0007]

BEST MODE FOR CARRYING OUT THE INVENTION Preferred embodiments of the deodorizing / dust removing method for a hotel guest room according to the present invention will be described in detail below with reference to the drawings. FIG. 1 is a schematic configuration diagram of a deodorizing / dust removing air conditioning system that realizes a deodorizing / dust removing method according to the present invention.
A supply duct 13 for supplying outside air is provided in, for example, the ceiling of each guest room 11, and the supply duct 13 is connected to the supply side of an external air conditioner 15 provided in the air conditioner room.

The tip of the supply duct 13 is connected to an outlet 17 that opens in the passenger compartment 11. A fan coil unit 19 is provided in the ceiling of each cabin 11, and the supply side of the fan coil unit 19 is connected to the air outlet 17. Therefore, from the air outlet 17, the outside air from the external air conditioner 15 and the circulating air passing through the fan coil unit 19 join together and are blown out.

The fan coil unit 19 is provided with a filter 23, and the filter 23 collects a certain amount of dust from the air passing through the fan coil unit 19.
The fan coil unit 19 is provided with a heat exchanger 25, and the heat exchanger 25 can individually adjust the temperature of the cabin air circulated by the blower fan 27. Further, the fan coil unit 19 is provided with a humidifying unit 29, and the humidifying unit 29 can individually adjust the humidity of the circulated cabin air. The fan coil unit 1
When the pressure loss of 9 becomes large, the humidifying unit 29
May be provided inside the supply duct 13 instead of inside the fan coil unit 19 (see the broken line position in the figure).

Therefore, the fan coil unit 19 collects the air in the passenger compartment 11 from the letter opening 31 provided in the passenger compartment 11 and passes the air taken in through the filter 23 to the heat exchanger 25 and the humidifying unit 29. After adjusting the temperature and humidity individually for each guest room, the collected air is blown out to the outlet 17
Will be blown out into the guest room 11 again.

An exhaust port 33 is provided in, for example, a bath / toilet of each cabin 11, and the exhaust port 33 is connected to an exhaust device 37 provided in the air conditioner room through an exhaust duct 35. The supply duct 13 and the exhaust duct 35 in each of the passenger rooms 11 described above are slightly larger in size than conventional ventilation ducts. For example, when the conventional ventilation volume per guest room is 50 to 120 m ³ / H, the outer diameters of the supply duct and the exhaust duct are 100 to 150 mm, whereas the supply duct 13 and the exhaust duct 35 of the present system are , 150 to 175 mm. Since the supply duct 13 and the exhaust duct 35 in each guest room 11 are formed large, the ventilation volume per one guest room can be 50 to 350 m ³ / H.

Motor dampers 39a and 39b are provided between the supply duct 13 and the exhaust duct 35 and the supply duct and the exhaust duct on the backbone side.
The motor dampers 39a and 39b are connected via a control panel 41 to a central control device 43 and a ventilation switch 45 provided in each passenger compartment 11. Motor damper 39a, 3
The opening and closing degree of 9b is determined by a control signal sent from the central control device 43 or the ventilation switch 45. Therefore, when both motor dampers 39a and 39b are fully opened, the supply duct 13 and the exhaust duct 35 in the passenger compartment 11 are fully opened, and ventilation of about 350 m ³ / H per passenger room can be performed.

A medium-performance filter 47, for example, is attached to the external air conditioner 15, and the medium-performance filter 47 removes dust from the intake air. Further, the external air conditioner 15 is provided with an odor control device 49 so that odor can be effectively erased.

A deodorizing / dust removing method using the deodorizing / dust removing air-conditioning system thus configured will be described. When the passenger compartment 11 is used, the motor dampers 39a and 39b are opened to a predetermined opening (5 passenger compartments by a signal from the central controller 43).
It opens at an opening degree that allows a ventilation amount of 0 to 120 m ³ / H) and supplies the outside air from the supply duct 13 into the passenger compartment 11 through the air outlet 17. At the same time, the same amount of air as the supplied outside air is exhausted from the exhaust duct 35. In this state, the air in each cabin 11 is circulated to the fan coil unit 19 to individually adjust the temperature and humidity. At this time, the collected air passes through only the filter 23 and is taken into the fan coil unit 19, so that there is no pressure loss as in the case where the conventional dust removing unit and deodorizing unit are attached. In addition, when the guest who checked in in the guest room smokes and the smoke and the smell of cigarettes fill the room, the operation signal of the ventilation switch 45 in the guest room causes the motor dampers 39a and 39b in the guest room 11 to be fully opened, which occurs. Exhaust smoke and odors to the outside.

When the use of the guest room 11 is finished and, for example, a check-out process is performed and a signal to that effect is input to the central control unit 43, or a signal indicating that the cleaning of the guest room 11 is started is centrally controlled. When input to the device 43, the central control device 43 sends a control signal for fully opening the motor dampers 39a, 39b of the corresponding passenger compartment 11. By fully opening the motor dampers 39a, 39b, the ventilation volume is increased to about 350 m ³ / H, and dust generated during cleaning and odors such as body odor and cigarette odor remaining at the end of guest room use are discharged through the exhaust duct 35. Exhaust from inside 11 to outside.

The increase of the ventilation amount by fully opening the motor dampers 39a, 39b is, for example, automatically performed after the predetermined time has elapsed from the time of inputting the check-out signal, or after the passage of a predetermined time after the completion of the cabin cleaning, the normal ventilation amount (50 ~ 12
Ventilation volume of 0 m ³ / H) to reduce the deodorization of guest room 11.
Finish dust removal.

According to this deodorizing and dust removing method, a checkout signal or a cleaning start signal is received, the ventilation amount is greatly increased as compared with the conventional one, and dust and odor are removed from the exhaust duct 35.
Since it is decided to discharge the dust from the circulating air, it is possible to surely perform the dust removal and the deodorization as compared with the conventional method of collecting the dust and the like from the circulating air by the dust removal unit and the deodorization unit.

Moreover, since only the filter 23 is attached to the return coil of the fan coil unit 19, there is no risk of degrading the performance of the fan coil unit 19 due to pressure loss as in the case of attaching the dust removing unit and the deodorizing unit.

In addition, the odor and the dust are all discharged to the outside and collected in the dust removing unit and the deodorizing unit, so that the cabin 1
Since it does not remain in the passenger compartment 1, it is possible to prevent an accident in which dust and odor leak from these units into the passenger compartment 11.

Further, since the motor dampers 39a and 39b only have to be provided, the initial cost is low. Also, there is no need to regularly inspect these units, unlike when installing a dust removal unit or deodorization unit.
No need for complicated maintenance.

In the above embodiment, the case where the deodorizing / dust removing method according to the present invention is used in the guest room 11 of the hotel has been described as an example. However, in the deodorizing / dust removing method according to the present invention, the ventilation capacity is set in the target space. By setting appropriately according to the volume,
It can also be used in smoking areas, restaurants, etc. where dust and odor are a problem. Further, the deodorizing / dust removing method according to the present invention can temporarily introduce a large amount of outside air, and therefore, for example, during cooling in the intermediate period and winter, without using a cold heat source, only by using low temperature outside air, cooling can be performed. This can be done, which can also reduce the air conditioning energy.

[0022]

As described in detail above, according to the method for deodorizing and removing dust in a hotel guest room according to the present invention, a checkout signal or a cleaning start signal is received, and dust and odor are discharged from the guest room by ventilation. Therefore, the dust removal and deodorization can be performed more reliably than the conventional method in which dust and odor are removed from the circulating air by the dust removal unit and the deodorization unit. Further, since the dust removing unit and the deodorizing unit are not attached, there is no fear that the performance of the fan coil unit is deteriorated due to the pressure loss. Further, since all the odors and dust are discharged to the outside, the collected dusts and odors will not leak into the cabin. Further, since the substantial expansion of the device is only to provide the motor damper, the initial cost can be reduced, and the complicated maintenance as in the case where the dust removing unit and the deodorizing unit are attached can be eliminated. .
