Description

FIELD OF THE INVENTION [0001] The present invention relates to an integrated system of a chilled beam air conditioning system and a fire extinguishing system,

[0001] The present invention relates to a chilled beam air conditioning system, and more particularly, to a chilled-beam air conditioning system in which a chilled beam air conditioning facility and a sprinkler fire- And to an integrated system of fire-fighting equipment and fire-fighting equipment using a common use pipe.

Generally, air conditioning equipment for heating and cooling inside the building and fire extinguishing equipment for fire are separately constructed for buildings of a certain scale. At this time, the air conditioner is operated during the heating / cooling period, and the fire extinguishing system has a characteristic of keeping the air conditioner at all times for emergency operation in case of fire.

On the other hand, the modern construction method is being used in a simple and efficient way, away from the labor-intensive method of the construction workers in the past, and a large amount of building members are being produced at the factory and assembled with the floor and outer wall structures at the construction site. However, the facilities such as air conditioning, sanitation, fire extinguishing facilities, lighting, and ducts in the ceiling are exposed and complexly constructed, making it difficult to efficiently construct and modularize the ceiling equipment.

In modern buildings, 40% to 50% of the total building energy consumption and 40% of the conveying power for air-conditioning air are used. Therefore, 20% of the total.

Recently, various energy saving technologies have been developed and introduced in order to reduce energy consumption of buildings. For example, Chilled Beam Air Conditioning System is one of the technologies that have recently attracted domestic and international attention as a building energy saving technology.

A fundamental difference between the chill-beam air-conditioning system and the conventional air-conditioning system is that the chill-tip air-conditioning system is a system for separating the air-conditioning and ventilation, and is similar to the radiating and heating system in terms of supplying cold water and hot water. Convective heat exchange. At this time, in the case of the chilled beam air conditioning system, the water transmitted through the pipe passes through the "chilled beam" installed near the ceiling or the ceiling and performs heat exchange with the room air.

This chilled beam air conditioning system is developed to increase the cooling effect of the ceiling radiation panel system, which can satisfy the comfort of the living space and energy saving by using the radiation and convection cooling effect. In other words, such a chilled beam air conditioning system is a new concept air conditioning system that can minimize draft by turbulent air movement. It can be easily installed on the ceiling of an existing building with low installation height, ), It is a system that has advantages such as high heat exchange efficiency, low noise, and reduction of piping installation area.

In addition, this chilled beam air conditioning system can reduce the transportation power for air conditioning, has many advantages in terms of construction and indoor environment, and spreads rapidly in Europe. In Korea, Products that meet the operating conditions of the air conditioning system are being developed.

Specifically, the chilled beam air conditioning system, which is rapidly spreading mainly in Europe, is a system capable of mass production by concentrating the existing ceiling systems, which can reduce the floor height and reduce construction and management costs. Compared with the conventional air-conditioning system, the chilled-beam air-conditioning system adopts the water-air conditioning system, which reduces the circulating air volume by 75 to 85% compared with the conventional system. It can be reduced by around 20%. In addition, since the chill beam system provides a pleasant air conditioning environment and a beautiful ceiling, it is advantageous in various aspects such as shortening of bed height, reduction of conveying power, economical efficiency of construction and maintenance, Technology development is required.

Recently, the increase in high-rise and large-scale buildings has led to an increase in the demand for built-in facilities, and accordingly, there is an increasing demand for improving the efficiency of construction through the combination of two or more facility technologies. For example, the construction of built-in facilities such as "air conditioning, electricity, digestion, hygiene, interior", etc., can reduce construction time and construction cost of each facility construction by integrally installing each facility.

However, no technology has yet been developed to integrate and operate the Chilabin air conditioning system and fire extinguishing system.

The fire extinguishing system is a sprinkler system, A fire extinguisher main pump 120, a fire extinguishing auxiliary pump 130, a pressure tank 140, a fire extinguishing pipe 150, an alarm valve 160 and a sprinkler 170. The chilled beam air conditioning system includes an expansion tank 210, a circulation pump 220 for air conditioning, a cold / hot water system 230, a cold / hot water pipe 240, a water hammer prevention device 250, a common pipe 260 for air conditioning and extinguishing, And a chilled beam 270.

The chilled beam air conditioning system includes an expansion tank 210, a circulation pump 220 for air conditioning, a cold / hot water system 230, a cold / hot water pipe 240 and a chilled beam 270, 240 are directly supplied to the chilled beams 270 through the ceiling of the building.

Here, the cold / hot water pipe 240 of the chilled beam-type air conditioning equipment may be a pipe made of a copper alloy (KS D 5301) having a diameter of 1/2 inch (15A).

The fire extinguishing system includes a fire extinguishing water tank 110, fire extinguishing circulation pumps 120 and 130, a pressure tank 140, a fire extinguishing pipe 150, an alarm valve 160, a water hammer cushion 250, (150) is connected to a ceiling of a building to spray water into the flame in response to a rise in the room temperature due to a fire. The automatic fire extinguishing system includes a sprinkler head Lt; / RTI >

Here, the fire extinguishing piping 150 of the fire extinguishing system is formed of a carbon steel pipe (KS D 3507) so as to meet the performance standard of maintaining a maximum head pressure of 12 kg / cm 2 for 20 minutes or more, If it is more than 1.2 MPa, it may have carbon steel pipe for pressure piping (KS D 3562) or equivalent strength, corrosion resistance and heat resistance.

The common piping 260 for air conditioning and extinguishing is connected to the chill beam 270 of the chill lamp control system and the fire extinguishing system 250 to connect the hot water pipe 240 and the fire extinguishing pipe 150 of the chill- And is commonly installed at the front end of the sprinkler 170 of the facility. Here, the common pipe 260 for air conditioning and extinguishing may be a carbon steel pipe for piping (KS D 3507) commonly used in the above-mentioned chilled-beam air-conditioning system and the fire extinguishing system.

Accordingly, the chilled-beam air-conditioning system is always operated during the cooling / heating period, and the fire extinguishing system can maintain the standby state at all times for operation in the event of a fire emergency.

Specifically, the water tank for fire extinguishing of the fire extinguishing system is a fire extinguishing water source. In order to supply fire extinguishing water in a fire, the amount of water to be supplied must be secured in proportion to the number of heads. In the case of one closed type sprinkler, For example, it is necessary to maintain a flow rate of 80 liters for 20 minutes or longer, and a water amount of 1.6 cubic meters or more is required. In the case of 30 or less open sprinklers, a quantity of 1.6 cubic meters or more per head is required. Here, the fire extinguishing water tank 110 is a water bath for fire extinguishing that can be maintained for 20 minutes at a flow rate of 80 liters per minute, which is calculated based on the number of sprinkler heads, and is preferably at least 2,000 liters.

The circulation pump for fire extinguishing, which is a pressurized water supply and discharge device, may be composed of a main fire extinguishing circulation pump 120 and an auxiliary fire extinguishing circulation pump 130. The fire extinguishing circulation pumps 120, And receives the signal generated from the alarm valve 160, which is a water flow detection device, to pressurize and send water. For example, according to the Sprinkler Fire Safety Standard (NFSC103), the rated discharge pressure should be more than 1kg / ㎠ to 12㎏ / ㎠ at the tip of one sprinkler head, 80 liters / min should be maintained. Examples of such pressurized water supply and reception apparatuses include an expensive water tank, a pressure tank, and a pump system. For example, a high-price water tank is a system that pressurizes water by utilizing the potential energy of water in a water tank, while a pressure water tank system is a system that pressurizes the inside of a water tank to send and receive water. In the case of the pumping method, the pressurized water supply is started by the signal generated from the alarm valve 160.

The pressure tank 140 normally functions as a pressurized water supply / discharge device, and pressurized by pressurized air to the head of the sprinkler 170 via an alarm valve 160 as a water flow detection device, thereby enabling quick start of operation in an emergency.

The fire extinguishing piping 150 is a pipe for supplying water to the head of the sprinkler 170 from the fire extinguishing water tank 110. The fire extinguishing piping 150 is based on the material of the pipe in accordance with the working pressure. (KS D 3562) or more. However, in the case of a wet type sprinkler in which the inside of the fire extinguishing pipe 150 is filled with pressurized water, a pipe made of another material such as a copper alloy can be used. Although it is recommended that the fire extinguishing piping 150 is installed exclusively, it is specified that the fire extinguishing piping 150 can be combined with other facilities in the case of a building having 30 stories or less, provided that the performance of the sprinkler 170 is not problematic. For example, according to the fire safety standard (NFSC 103) piping standard, the fire extinguishing piping 150 can be used as a piping standard for the sprinkler facility, such as a carbon steel pipe for piping (KS D 3507) (KS D 3562) for pressure piping or equivalent equivalent strength, corrosion resistance and heat resistance. However, the piping of the wet sprinkler installation is capable of copper pipes for seamless piping of copper and copper alloy (KS D 5301).

The alarm valve 160 detects the water flow due to the opening of the sprinkler 170 in the event of a fire, generates an alarm, and generates a pump start signal.

The water hammer prevention device 250 can be operated at a pressure of 15 kg / cm 2 or less to prevent a water hammer occurring when the fire extinguishing circulation pumps 120 and 130 and the air conditioning circulation pump 220 are driven, have.

The expansion tank 210 is a facility similar to the pressure tank 140 of the fire extinguishing system. The expansion tank 210 is connected to the cold / hot water pipe 240 As shown in Fig.

The air conditioning circulation pump 220 is circulated by, for example, a flow rate of 3 liters or more per minute to supply and return air-conditioning water to each room.

The cold / hot water pipe 240 is a material for supplying cold / hot water supplied from the cold / hot water supply unit 230 to each room. The cold / hot water pipe 240, (KS D 5301) in order to improve the heat exchange performance at the heat exchanger inlet of each room.

The water hammer prevention device 250 is installed to prevent the water hammer occurring when the circulation pumps 120 and 130 for fire extinguishing and the circulation pump 220 for air conditioning are operated.

A common piping (260) for air conditioning and extinguishing is installed commonly in front of the sprinkler (170) and the chilled beam (270).

The chilled beam 270 is installed on the ceiling of the room, and receives fresh outside air and cold / hot water. For example, the chilled beam 270 supplies the fresh outside air required for the indoor air quality (IAQ) to the pressure chamber of the chilled beam through the OA duct, and supplies the cold / hot water required for the treatment of the cooling / And supplied to the cold / hot water coil of the chilled beam.

In order to improve the heat exchange performance at the inlet of the heat exchanger in each room, D 5301). For example, it is preferable to use a pipe made of a copper alloy (KS D 5301) having a diameter of 1/2 inch (15A) as the cold / hot water pipe 240 of the above-mentioned chilled-beam air-

In addition, the sprinkler facility is mainly constructed with a fire extinguishing pipe 150 made of carbon steel pipe (KS D 3507) in order to meet the performance standard of maintaining a maximum head pressure of 12 kg / cm 2 for 20 minutes or more in an emergency. At this time, when the sprinkler facility is a wet sprinkler facility, it is possible to use a seamless copper pipe as shown in the fire safety standard (NFSC103). For example, the fire extinguishing pipe 150 of the sprinkler facility is preferably a pipe made of a carbon steel pipe (KS D 3507) having a diameter of 1 inch (25A) or more.

이상 유량을 확보하고, 또한, 상기 스프링클러 설비의 순환펌프는 12㎏/㎠ 수두 이하의 펌프로서 80

이상의 유량을 확보해야 하므로, 이러한 펌프 설비를 칠드빔 공조설비와 스프링클러 설비에 동시에 사용하는 것은 곤란할 것으로 판단된다. Referring to FIG. 7, in the integrated system of the chill lamp and the fire extinguishing system according to the embodiment of the present invention, the circulation pump 220 for air conditioning of the chill lamp control system is circulated at a flow rate of 3 liters or more per minute, In the case of the circulation pump for fire extinguishing of the sprinkler facility, for example, the fire main pump 120 and the fire extinguishing auxiliary pump 130, in case of emergency, 80 liters per minute shall be met. In addition, a circulation pump for the fire extinguishment of a larger capacity than that of the air circulation pump 220 should be designed based on a criterion that the water supply pressure of 12 kg / cm 2 or more should be maintained for 20 minutes or more. Specifically, the circulation pump of the chilled-beam air-conditioning system is a pump having a head of 3 kg / cm < 2 &

And the circulation pump of the sprinkler facility is a pump of not more than 12 kg / cm < 2 >

The pressure tank 140 of the fire extinguishing system generates an initial flow rate simultaneously with the opening of the sprinkler head in the event of a fire so as to operate the circulation pumps for fire extinguishment 120 and 130 and cause the alarm valve 160 to generate an alarm. For example, the pressure tank 140 of the fire extinguishing system may be a pressure tank having an internal volume of 100 L between 1 kg / cm 2 and 15 kg / cm 2.

Also, in the case of the above-mentioned chilled-beam air-conditioning system, an expansion tank 210 is used as a facility similar to the pressure tank 140.
