Air-conditioning apparatus

Abstract

An air-conditioning apparatus includes: a housing; a first heat exchanger; a second heat exchanger; a first fan; a second fan; a control valve; and a controller that controls the control valve and the first and second fans. The housing includes a first air outlet and a second air outlet. The controller sets in the air-conditioning target space, a first area associated with the first air outlet and a second area associated with the second area, detects whether a person or persons are present or no person is present in each of the first and second areas, and controls the control valve and the first and second fans such that air conditioning is performed in the first area and an air-blowing operation is performed in the second area, when detecting that the person or persons are present in the first area and no person is present in the second area.

1 . An air-conditioning apparatus comprising:
 a housing;   a first heat exchanger provided in the housing;   a second heat exchanger provided in the housing;   a first fan provided in the housing and configured to send air to the first heat exchanger;   a second fan provided in the housing and configured to send air to the second heat exchanger;   a control valve configured to control a flow of refrigerant to the first heat exchanger and the second heat exchanger; and   a controller configured to control the control valve, the first fan, and the second fan,   wherein the housing includes   a first air inlet formed in one side surface of the housing and configured to allow air to flow to the first heat exchanger through the first air inlet,   a second air inlet formed in an other side surface of the housing that is located opposite to the one side surface, and configured to allow air to flow to the second heat exchanger through the second air inlet,   a first air outlet formed in a lower surface of the housing and configured to allow air subjected heat exchange at the first heat exchanger to be blown out, and   a second air outlet formed in the lower surface of the housing and configured to allow air subjected to heat exchange at the second heat exchanger to be blown out, and   wherein the controller is configured to set in the air-conditioning target space, a first area associated with the first air outlet and a second area associated with the second area, detect whether a person or persons are present or no person is present in each of the first area and the second area, and control the control valve, the first fan, and the second fan such that air conditioning is performed in the first area and an air-blowing operation in which air is blown is performed in the second area, when detecting that the person or persons are present in the first area and no person is present in the second area.   
     
     
         2 . The air-conditioning apparatus of  claim 1 , wherein the controller is configured to control the control valve to cause refrigerant to flow through the first heat exchanger, drive the first fan, control the control valve to stop a flow of the refrigerant to the second heat exchanger, and drive the second fan, when detecting that the person or persons are present in the first area and no person is present in the second area. 
     
     
         3 . The air-conditioning apparatus of  claim 1 , wherein the housing includes
 a first air passage in which the first fan is provided,   a second air passage in which the second fan is provided,   a partition provided between the first air passage and the second air passage.   
     
     
         4 . (canceled) 
     
     
         5 . The air-conditioning apparatus of  claim 1 , further comprising:
 first deflectors configured to adjust a flow direction of air that is blown from the first air outlet; and   second deflectors configured to adjust a flow direction of air that is blown from the second air outlet,   wherein the controller is configured to control the second deflectors to cause the air that is blown from the second air outlet to flow in a direction away from the first area, when detecting that the person or persons are present in the first area and no person is present in the second area.   
     
     
         6 . The air-conditioning apparatus of  claim 1 , further comprising an infrared sensor configured to detect infrared rays in the air-conditioning target space,
 wherein the controller is configured to detect, using the infrared sensor, whether the person or persons are present or no person is present in each of the first area and the second area.   
     
     
         7 . The air-conditioning apparatus of  claim 1 , further comprising a temperature detector configured to detect a temperature in the air-conditioning target space,
 wherein the controller is configured to control the control valve, the first fan, and the second fan such that a temperature of the first area and a temperature of the second area reach respective target temperatures.
