Description

Integrated air conditioner with ventilation structure {package type air-conditioner with ventilating structure}

The present invention relates to an integrated air conditioner having a ventilation structure, and more particularly, to an exhaust duct for exhausting air from the room to the outside through a condenser and a compressor at a lower end of a cabinet located in the room, and the air sucked from the room at the upper end. To form an indoor circulation duct that circulates back to the room through an evaporator, and an air supply duct for providing air supplied from the outside into the indoor circulation duct at the stop portion to integrate the air conditioner and to form an indoor ventilation structure. The present invention relates to an integrated air conditioner having a ventilation structure that can eliminate the outdoor unit installed in the room and provide a comfortable environment indoors by indoor ventilation.

In general, an air conditioner (air conditioner) refers to a device that maintains a comfortable state by automatically adjusting the indoor air temperature, humidity, etc. by a mechanical device. It is divided into separate type air conditioner which is composed of separate type.

As shown in FIG. 1, the separate type air conditioner is provided with a compressor 110 for compressing a refrigerant at high temperature and high pressure, and receives a gas refrigerant compressed at high temperature and high pressure. A condenser 120 for liquefying with a coolant is disposed, and an expansion mechanism 130 for depressurizing the high pressure and room temperature liquid refrigerant liquefied in the condenser 120 is provided.

In addition, an evaporator 140 is disposed to receive a low-temperature, low-pressure liquid refrigerant depressurized by the expansion mechanism 130 to take heat from the surroundings, and to phase change into a low-temperature, low-pressure gas refrigerant. A blowing fan 145 for blowing air is disposed, and a cooling fan 125 for sucking air and blowing air to the condenser 120 is disposed.

In the figure, the part divided by a dashed line at the point where the compressor 110, the condenser 120, and the cooling fan 125 are located is an outdoor unit 101, and the expansion mechanism 130, the evaporator 140, and the blower air. The part partitioned by the dotted line at the point where the fan 145 is located shows the indoor unit 102.

As shown in FIG. 2, typically, the indoor unit 102 is installed indoors, and the outdoor unit 101 is configured to be installed outdoors. The outdoor unit 101 and one side of the indoor unit 102 guide the flow of the refrigerant. Two refrigerant pipes 121 and 141 are connected to each other through the wall surface. The refrigerant pipes 121 and 141 are liquid refrigerant pipes 121 for connecting and supplying the liquid refrigerant from the condenser 120 of the outdoor unit 101 to the expansion mechanism 130 and the evaporator 110 of the indoor unit 102. In addition, the gas refrigerant from the evaporator 140 of the indoor unit 102 is divided into a gas refrigerant pipe 141 for connecting and supplying the compressor 110 of the outdoor unit 101.

When the air conditioner is configured as described above, when the power is applied, the compressor 110 of the outdoor unit 101 operates to compress the refrigerant at a high temperature and high pressure, and the refrigerant compressed at the high temperature and high pressure flows into the condenser 120 to supply a high pressure and a normal temperature. Phase change with liquid refrigerant.

Thus, the high pressure and room temperature liquid refrigerant passing through the condenser 120 is depressurized while passing through the expansion mechanism 130 of the indoor unit 102 through the liquid refrigerant pipe 121, and then flows into the evaporator 140 to reduce the low pressure and low pressure. The refrigerant cycle is evaporated, and the refrigerant cycle flowing into the compressor 101 of the outdoor unit 101 through the gas refrigerant pipe 141 is repeatedly performed.

In this process, while the compressor 110 is operated and the blower fan 145 and the cooling fan 125 are operated, the indoor and outdoor air is sucked and blown to the evaporator 140 and the condenser 120.

At this time, the indoor air sucked by the rotation of the blower fan 145 is blown to the evaporator 140, and the heat exchanger is cooled with cold cold air while the evaporator 140 takes away heat from the surroundings and evaporates, and is sucked by the cooling fan 125. The outdoor air is blown to the condenser 120 to cool the condenser 120 while the refrigerant in the condenser 120 is liquefied, and then discharged to the outside as hot air.

However, the detachable air conditioner as described above has not been provided with any means for ventilating the room, and it has been recognized that the installation of the ventilation device is impossible due to the characteristics of the structure. As a result, when used for a long time due to the continuous circulation of air in an enclosed room, the air is contaminated and thus there is a problem of harming the user's health such as a cooling bottle.

Accordingly, the operation of the air conditioner has to be opened and ventilated periodically during operation of the air conditioner, which is not only inconvenient to use but also causes a large temperature loss.

In addition, the detachable air conditioner as described above requires a mounting space because the outdoor unit is installed on the outside, so when there is no suitable mounting space such as a rooftop, there is a problem that it must be mounted to protrude out of the window. There is a problem that management is required according to the outdoor environment.

Accordingly, the present invention has been made in view of the above-mentioned problems, and integrated into a single cabinet without any distinction between the outdoor unit and the indoor unit by integrating the equipment for the refrigeration cycle and cold air circulation and having an indoor ventilation structure separately to the outdoor The purpose of the present invention is to provide an integrated air conditioner having a ventilation structure to solve the problems caused by the installation of the outdoor unit as well as the outdoor unit to be installed, as well as to achieve a comfortable environment indoors by the indoor ventilation action.
