Heat exchange unit and air-conditioning apparatus

Abstract

A heat exchange unit includes a heat exchanger and a drain pan detachable to the heat exchanger, the drain pan including a first drain pan having a flat shape installed on a first imaginary plane, and a second drain pan having a flat shape and installed on a second imaginary plane having a different angle with respect to the first imaginary plane, wherein the first drain pan is provided below the heat exchanger.

1 . A heat exchange unit comprising:
 a heat exchanger; and   a drain pan detachable to the heat exchanger,   the drain pan including
 a first drain pan being a member having a rectangular flat shape and installed on a first imaginary plane, and 
 a second drain pan having a flat shape and installed on a second imaginary plane extending at an angle with respect to the first imaginary plane, 
 the first drain pan
 being provided below the heat exchanger, and 
 having inwardly depressed recesses at adjacent two corners of the first drain pan, 
 
 the second drain pan being provided with protrusions for engaging with the recesses. 
   
     
     
         2 . The heat exchange unit of  claim 1 , wherein the first imaginary plane is substantially perpendicular to the second imaginary plane. 
     
     
         3 . The heat exchange unit of  claim 1 , wherein at least one of the first drain pan and the second drain pan includes an opening for flowing air. 
     
     
         4 . The heat exchange unit of  claim 1 , wherein the first drain pan and the second drain pan are connected to each other at respective one ends, and the second drain pan is provided with a projection for positioning the first drain pan. 
     
     
         5 . (canceled) 
     
     
         6 . The heat exchange unit of  claim 1 , wherein the first drain pan is symmetrically shaped relative to at least either of
 an imaginary reference line extending in a longitudinal direction of the first drain pan and passing through a lateral center of the first drain pan, and   an imaginary reference line extending in a lateral direction of the first drain pan and passing through a longitudinal center of the first drain pan.   
     
     
         7 . The heat exchange unit of  claim 1 , wherein the second drain pan is symmetrically shaped relative to at least either of
 an imaginary reference line extending in a longitudinal direction of the second drain pan and passing through a lateral center of the second drain pan, and   an imaginary reference line extending in a lateral direction of the second drain pan and passing through a longitudinal center of the second drain pan.   
     
     
         8 . An air-conditioning apparatus comprising:
 the heat exchange unit of  claim 1 ,   an air blower unit, and   a body housing the heat exchange unit and the air blower unit.   
     
     
         9 . The air-conditioning apparatus of  claim 8 , wherein
 at least one of the first drain pan and the second drain pan includes an opening for flowing air, one of opposite surfaces of the body is provided with a first vent and an other of the opposite surfaces of the body is provided with a second vent, and the heat exchange unit is provided such that the opening is opposed to an opening of the first vent and an opening of the second vent.   
     
     
         10 . The air-conditioning apparatus of  claim 8 , wherein an outer surface of a receiving portion of the second drain pan is provided to be opposed to one of side surfaces of the body. 
     
     
         11 . The air-conditioning apparatus of  claim 10 , wherein at least one surface of the side surfaces of the body not opposing the outer surface of the receiving portion of the second drain pan is configured as a detachable side surface panel. 
     
     
         12 . The air-conditioning apparatus of  claim 8 , further comprising a fixing unit for fixing the drain pan to the body.
