Definitions

  • the present invention relates to an air conditioner and a control method thereof.
  • Air conditioners are cooling/heating systems that cool an indoor space by repeatedly performing a series of operations, including suctioning indoor air, performing heat-exchange between a low-temperature refrigerant and the suctioned indoor air, and discharging the heat-exchanged air into the indoor space, or heats the indoor space by repeatedly performing the above operations for cooling in reverse.
  • Such an air conditioner has a series of cycles constituted by a compressor, a condenser, an expansion valve, and an evaporator.
  • Air conditioners may be largely classified into separation type air conditioners in which indoor and outdoor units are separately installed and integrated air conditioners in which the indoor and outdoor units are integrated. In recent years, the separation type air conditioners are preferred in consideration of an installation space and noise.
  • An indoor unit of such an air conditioner includes an indoor heat exchanger in which a refrigerant circulated into the air conditioner with indoor air are heat-exchanged with each other.
  • the indoor air absorbs or dissipates heat through the heat-exchange with the refrigerant.
  • WO 2012/014345 A1 relates to a heat pump comprising a first bypass pipe and a second bypass pipe.
  • One end of the first bypass pipe is connected to a main pipe connecting a compressor to an indoor heat exchanger, and the other end of the first bypass pipe is branched and connected to the main pipe on the inlet side of each outdoor heat exchanger.
  • One end of the second bypass pipe is connected to an injection port which is in communication with a compression chamber being compressed in the compressor, and the other end of the second bypass pipe is branched and connected to the main pipe on the outlet side of each outdoor heat exchanger.
  • Fig. 1 is a graph illustrating air speed distribution in upper and lower positions of an indoor heat exchanger. Referring to Fig. 1 , a speed of air passing through the indoor heat exchanger varies according to vertical positions of the indoor heat exchangers.
  • an object of the present invention is to improve the heat-exchange efficiency. This object is achieved with the features of the claims.
  • the invention provides an air conditioner and a control method thereof.
  • Fig. 2 is a perspective view illustrating an indoor unit of an air conditioner according to an embodiment of the invention. Although a ceiling type indoor unit is provided in Fig. 2 , the present invention is not limited to the ceiling type indoor unit.
  • an indoor unit 100 of an air conditioner includes a front panel 120 defining an edge portion of an outer appearance of a bottom surface thereof, a suction grill 130 disposed in a central portion of the front panel 120 to introduce indoor air into the indoor unit 100, a cabinet 140 defining an upper outer appearance of the indoor unit 100 and including a plurality of components therein, and a base 150 covering a top surface of the cabinet 140 and configured to mount the indoor unit 100 on a ceiling.
  • An overall outer appearance of the indoor unit 100 is defined by the front panel 120, the suction grill 130, the cabinet 140, and the base 150.
  • the front panel 120 is punched in a square shape so that the suction grill 130 is mounted therein. Also, discharge holes 160 having a rectangular shape are defined in a bottom surface of the front panel 120. The discharge holes 160 discharge air heat-exchanged within the indoor unit 100 again into an indoor space. Front, rear, left, and right portions of the front panel 120 are punched in the same shape to define the discharge holes, respectively.
  • a louver 170 configured to force a flow direction of the air discharged into the indoor space through each of the discharge holes 160 is disposed in the discharge hole 160.
  • the louver 170 has a square plate shape corresponding to a shape and size of the discharge hole 160.
  • the louver 170 is connected to a motor (not shown) for generating rotation force to rotate, thereby forcing a flow direction of air.
  • the suction grill 130 having an approximately square shape is mounted in a central portion of the front panel 120. As described above, the suction grill 130 suctions indoor air into the indoor unit 100. Thus, a plurality of suction holes 180 that are longitudinally cut in a horizontal direction and vertically penetrated are defined in a central portion of the suction grill 130.
  • a blower unit (not shown) for forcibly introducing the indoor air into the indoor unit 100 and a heat exchanger 200 in which the air introduced into the indoor unit 100 is heat-exchanged with the refrigerant are disposed above the suction grill 130, i.e., within the cabinet 140.

  • the plurality of heat exchangers may be independently provided, or one heat exchanger may be distinguished according to a portion of a refrigerant tube.
  • the plurality of heat exchangers 200a, 200b, and 200c may be successively referred to as a first heat exchanger 200a, a second heat exchanger 200b, and a third heat exchanger 200c when defined from a heat exchanger close to the front panel 120. That is to say, the plurality of heat exchangers 200a, 200b, and 200c may be successively referred to as a third heat exchanger 200c, a second heat exchanger 200b, and a first heat exchanger 200a when defined from a heat exchanger close to the base 110.
