Description

[0001] The present invention relates to an outdoor unit having a fire extinguishing system,

The present invention relates to an outdoor unit equipped with a fire extinguishing facility, and more particularly to an outdoor unit provided with a fire extinguishing facility capable of quickly extinguishing a fire in an outdoor unit fire.

Generally, an air conditioner uses a cooling cycle to liquefy a refrigerant gas compressed at a high temperature and a high pressure in a compressor by a condenser, change a liquid refrigerant from an expansion valve to a low temperature and a low pressure, So as to maintain the temperature suitable for the activity by supplying cold air to an enclosed indoor space such as an office, a room, or a building in a hot summer in summer.

Such air conditioners are widely used not only for the above-mentioned buildings but also for residential areas where mariners of ships and offshore structures live.

1, the air conditioner is divided into an outdoor unit 1 including a compressor and a condenser, and an indoor unit (not shown) including an expansion valve and an evaporator.

In this case, the condenser disposed in the outdoor unit 1 serves as a heat exchanger for evaporating the heat in the evaporator and releasing the heat of the room, which has been absorbed, to the outside while being liquefied.

Therefore, the condenser disposed in the outdoor unit 1 is air-cooled by a cooling fan so that heat exchange can be effectively performed.

Here, the outdoor unit 1 will be described in more detail with reference to FIG.

The outdoor unit 1 includes a compressor 4 installed in the outdoor unit case 2 for compressing the refrigerant introduced through the refrigerant pipeline 3, a condenser 5 for condensing the refrigerant compressed in the compressor 4, And a cooling fan 7 axially coupled to the motor 6 for exchanging heat generated in the condenser 5.

The outdoor unit case 2 is provided with an inlet 8 through which air is sucked by the rotation of the cooling fan 7 and an outlet 9 through which the heat exchanged through the condenser 5 is discharged.

On the other hand, as the cooling / heating capacity increases, the outdoor units 1 are installed mainly outside the building. Thus, the outdoor units 1 installed outside the building should be designed to be robust against the external environment such as rain or snow.

In particular, when the indoor unit is exposed to an outdoor environment having a high temperature in summer, a fire may occur in the outdoor unit (1).

This is because if the operation of the motor 6 can not be normally performed due to accumulation of dust inside the motor 6 in the outdoor unit case 2, the cooling operation of the cooling fan 7 can not be performed smoothly, The internal construction may overheat and fire may occur.

At this time, since the fire in the outdoor unit (1) is difficult to grasp at an early stage, there is a problem that the fire can not be suppressed at the initial stage,

Therefore, there is a demand for a fire extinguishing facility in the outdoor unit itself.

Hereinafter, an outdoor unit (hereinafter referred to as an "outdoor unit") having a fire extinguishing system according to a preferred embodiment of the present invention will be described with reference to FIGS. 3 and 4 attached hereto.

The outdoor unit has a technical feature that a fire extinguishing facility is installed in the case so that the fire can be quickly suppressed in the early stage in case of fire due to overheating of the motor.

The outdoor unit includes a case 100, a cooling fan 200, and a fire extinguishing facility 300.

The case 100 constitutes an appearance of the outdoor unit and serves to protect each component from the outside.

Next, the cooling fan 200 supplies the wind to the condenser 5 to cool the heat generated during the condensation of the refrigerant.

At this time, the cooling fan 200 includes a fan 210 and a motor 220.

That is, the fan 210 axially coupled to the motor 220 is rotated by the power of the motor 220.

Next, the fire extinguishing system 300 suppresses the fire when a fire occurs in the case 100, and is installed in the case 100.

The fire extinguishing system includes an extinguishing agent container 310, a connection pipe 320, a support 330, and a spray nozzle 340.

The extinguishing agent container 310 is a container for storing a medicine for digestion, and is installed on one side of the case 100.

There are various kinds of fire extinguishing agents depending on the fire extinguishing mechanism, and examples of the fire extinguishing agents include foam, powder, halon, and carbon dioxide.

Double powders are the most commonly used extinguishing agents for fire extinguishers. They are used in a way that they are sealed in powder form in a container and sprayed at high pressure through a pressure relieving method.

At this time, the fire extinguishing agent generates carbon dioxide gas by pyrolysis, and the fire is extinguished by suffocation and cooling.

The fire extinguishing agent stored in the fire extinguishing agent container 310 according to the present invention is preferably a powder fire extinguishing agent, but is not limited thereto.

Meanwhile, the extinguishing agent is stored in the extinguishing agent container 310 at a high pressure.
