Description

Portable air conditioner for both air conditioning and heating

The present invention relates to an air conditioner, and more particularly, to a portable air conditioner (portable air-conditioner) that can also serve as heating and cooling.

In general, an air conditioner cools a room by vaporization heat absorbed by liquefying refrigerant compressed in a compressor in a condenser and then vaporizing it in an evaporator through an expansion valve. , It is a device that can be heated by installing a heater inside.

This air conditioner is gradually expanding its use area, and is divided into a fixed type and a movable type that are installed at a predetermined place.

In particular, the portable air conditioner among the movable air conditioners is free to move, so that the user can appropriately cool the air at a desired position.

This conventional portable air conditioner is shown in FIG.

A barrier film 14 for dividing the internal space into the first and second chambers 12 and 13 is formed in a horizontal direction in a case 11 forming an exterior, and a caster is provided at a lower end of the case 11. 15) is installed and can be moved.

In the first chamber 12, a compressor 16 for compressing a refrigerant is installed, and a condenser 17 is connected to the compressor 16 to condense the compressed high-pressure steam refrigerant into a high-pressure liquid refrigerant. An expansion valve 18 for connecting the condensed high pressure liquid refrigerant to the low pressure liquid refrigerant to the condenser 17 is connected.

In addition, a blower 19 for blowing warm air discharged to the outside of the condenser 17 to the outside is installed in the first chamber 12, and an air discharge port 20 corresponding to the air discharge port is formed. A flexible duct 21 is provided at 20.

On the other hand, the second chamber 12 is provided with an evaporator 22 for vaporizing a low pressure liquid refrigerant, which has been pressure-falled by the expansion valve 18, into a low pressure steam refrigerant. The low pressure vapor refrigerant evaporated in the evaporator 22 flows into the compressor 16 and is compressed again.

In addition, a grille 23 through which air can be discharged is formed in a part of the case 11 of the second chamber 12, and a blowing fan 24 is installed at an adjacent position of the evaporator 22 to vaporize the refrigerant. Cold air formed is discharged into the room through the grill (23).

However, such a conventional portable air conditioner was used only when cooling the room using cold air generated from the evaporator 22. Therefore, it is useless in cold season or cold place.

The present invention is to solve such a conventional problem, it is an object of the present invention to provide a portable air conditioner that can also serve as heating and cooling.
