Problems solved by technology

[0013] A disadvantage of the conventional air conditioner is that, as a method of controlling the cooling capacity of the air conditioner according to the cooling load, the refrigerant discharged from the compressor 2 is divided to adjust the flow rate of the refrigerant
However, there is a limit to changing the flow rate of the diverted refrigerant according to the external load
Also, since the power consumption required to drive the compressor is constant, conventional air conditioners have excessive power consumption and are therefore energy inefficient

Embodiment Construction

[0032] Embodiments of the present invention will be described below with reference to the drawings.

[0033] image 3 is a simplified structural view schematically showing an air conditioner according to an embodiment of the present invention. Figure 4 is a simplified structural diagram schematically showing the inside of a heat exchanger provided in an air conditioner according to an embodiment of the present invention.

[0034] like image 3 As shown, the air conditioner according to the present invention includes: a compressor 50 to compress the low-temperature and low-pressure gaseous refrigerant into a high-temperature and high-pressure state; 54) to condense the refrigerant discharged from the compressor 50 into a liquid refrigerant by radiating heat to the surroundings; the expansion element 56 is to expand the liquid refrigerant condensed by the condenser into a low-temperature and low-pressure gas / liquid two-phase refrigeration agent; and an evaporator (ie, the in...

Abstract

The present invention discloses a heat exchanger used in an air conditioner, which has a path conversion unit in a tube forming a refrigerant path. The path switching unit is used to switch the flow path of the refrigerant passing through the tube according to the cooling or heating load, thereby adjusting the flow rate of the refrigerant. Using the path conversion unit has the effect of realizing effective control of its cooling or heating capacity according to the external load.

Description

technical field [0001] The present invention relates to an air conditioner, and more particularly, to a heat exchanger including a path switching element for switching a refrigerant flow path, thereby realizing an ability to easily control cooling or heating according to an external load, It also relates to an air conditioner using the heat exchanger. Background technique [0002] Generally, an air conditioner is a device for cooling or heating a room to create a more comfortable room environment. Air conditioners draw in room air to heat or cool the air, and discharge the heated or cooled air into the room. [0003] figure 1 is a diagram schematically showing the structure of a conventional air conditioner. figure 2 is a diagram schematically showing the inside of a conventional heat exchanger. [0004] like figure 1 As shown, the conventional air conditioner includes: compressor 2, which compresses the gaseous refrigerant at low temperature and low pressure into a hi...
