Description

Air Conditioning Equipment {AIR CONDITIONER}

The present invention relates to an air conditioner that maintains indoor air in a comfortable state by adjusting a certain space to a temperature, humidity, and airflow distribution suitable for human activity.

In general, an air conditioner is a cooling / heating system that cools a room by a repetitive action of inhaling hot air in a room, exchanging heat with a low-temperature refrigerant, and then discharging it into the room. Compressor-condenser-expansion valve-evaporator which forms a series of cycles.

In addition, the air conditioner of recent years has been dehumidified after performing a dehumidification process while circulating the humid air and the air purifying function to suck and filter the polluted air in the room in addition to the heating and cooling of the air conditioning space and re-supplied into the air conditioning space. It also has various additional functions such as a dehumidification function that supplies air back to the air conditioning space.

The air conditioner may be classified into a separate type air conditioner in which the outdoor unit and the indoor unit are separately installed, and an integrated air conditioner in which the outdoor unit and the indoor unit are integrally provided.

In addition, recently, a multi-type air conditioner for sharing an outdoor unit by connecting a plurality of indoor units to one outdoor unit has been used. Such a multi air conditioner can obtain the effect of installing a plurality of conventional separate air conditioner, it is also possible to add an indoor unit according to the needs of the user.

The outdoor unit constituting the air conditioner includes an outdoor heat exchanger and a compressor for exchanging heat and refrigerant outside the air conditioning space in which the outdoor unit is installed. Therefore, the refrigerant circulated in each indoor unit is collected in the same outdoor unit, and the process of distributing the indoor unit through the compression process and the condensation process (at the time of indoor cooling) is repeated.

Such a distribution process of the refrigerant may be performed through a distribution unit fixed to the outdoor unit for separate refrigerant collection and distribution, rather than having a distribution pipe branched according to the number of indoor units of the compressor or outdoor heat exchanger.

Such a distribution unit connects the indoor unit and the outdoor unit, collects the refrigerant with a compressor or an outdoor heat exchanger inside the outdoor unit, and distributes the refrigerant to the indoor unit having respective cooling conditions. Therefore, each indoor unit and the distribution unit must be connected by a pipe to which the refrigerant is supplied and a pipe to be recovered.

In addition, the outdoor unit includes a blower fan to exchange heat between the outdoor air and the refrigerant to condense or evaporate the refrigerant by the air sucked using the air outside the outdoor unit. Therefore, the outdoor unit may be installed to have a certain direction in consideration of the blowing direction of the blowing fan. That is, the outdoor unit may be installed so that the direction of the wind discharged from the outdoor unit faces a certain direction.

As described above, the outdoor unit is installed in consideration of the discharge direction of air. When the direction in which the distribution unit is provided in the outdoor unit does not match the direction in which the indoor unit is installed, the refrigerant pipe connecting the distribution unit and the indoor unit should be installed bypassing the outdoor unit. do.

As such, when the distribution unit is fixed to the outdoor unit and the refrigerant pipe connected to the distribution unit is installed bypassing the outdoor unit, the refrigerant pipe is bent a plurality of times to generate a flow resistance of the refrigerant, thereby increasing the energy efficiency of the air conditioner. There is a problem that is reduced.

In addition, while there are two refrigerant pipes connecting the outdoor unit and the distribution unit, the refrigerant pipe connected to the plurality of indoor units in the distribution unit uses at least two pipes per one indoor unit. Therefore, when the distribution unit is fixed to the outdoor unit, there is a problem that the refrigerant pipe branched from the outdoor unit and connected to the plurality of indoor units is complicated and long, which is not good in appearance.

An object of the present invention is to provide an air conditioner having a distribution unit that can be installed to face the installation direction of the indoor unit irrespective of the installation direction of the outdoor unit.

Another object of the present invention is to provide an air conditioner having a distribution unit detachable from an outdoor unit.
