Heat exchanger and ventilator

Abstract

A heat exchanger according to an embodiment includes an air supply path through which supply air supplied to a target space from the outside of the target space passes; an exhaust path through which exhaust air discharged from the target space to the outside of the target space passes; a partition member that divides the air supply path and the exhaust path and performs heat exchange between the supply air and the exhaust air; a separation member that adsorbs moisture in the air or discharges the adsorbed moisture to the air; and a decompression path that is provided at the air supply path side, is divided from the air supply path by the separation member, and is connected to a decompression pump.

1 . A heat exchanger comprising:
 an air supply path through which supply air supplied to a target space from outside of the target space passes;   an exhaust path through which exhaust air discharged from the target space to the outside of the target space passes;   a partition member that divides the air supply path and the exhaust path and performs heat exchange between the supply air and the exhaust air;   a separation member arranged at an air supply path side that adsorbs moisture in air or discharges adsorbed moisture to the air; and   a decompression path provided at the air supply path side, divided from the air supply path by the separation member, and connected to a decompression pump.   
     
     
         2 . The heat exchanger according to  claim 1 , wherein the separation member is provided as a spacer that maintains a space between the partition member and one of the air supply path and the exhaust path. 
     
     
         3 . The heat exchanger according to  claim 1 , wherein the separation member includes,
 a material having deliquescence, and   a porous member or a porous membrane.   
     
     
         4 . The heat exchanger according to  claim 1 , wherein the separation member have a convex part, and the decompression path is formed between the separation member and the partition member. 
     
     
         5 . The heat exchanger according to  claim 1 , wherein the separation member is of a cylindrical shape, and the decompression path is formed within the separation member. 
     
     
         6 . A heat exchanger comprising:
 an air supply path through which supply air supplied to a target space from outside of the target space passes;   an exhaust path through which exhaust air discharged from the target space to the outside of the target space passes;   a partition member that divides the air supply path and the exhaust path and performs heat exchange between the supply air and the exhaust air;   a separation member arranged at an exhaust path side that adsorbs moisture in air or discharges adsorbed moisture to the air; and   a decompression path provided at the exhaust path side, divided from the exhaust path by the separation member, and connected to a decompression pump.   
     
     
         7 . The heat exchanger according to  claim 6 , wherein the separation member is provided as a spacer that maintains a space between the partition member and one of the air supply path and the exhaust path. 
     
     
         8 . The heat exchanger according to  claim 6 , wherein the separation member includes,
 a material having deliquescence, and   a porous member or a porous membrane.   
     
     
         9 . The heat exchanger according to  claim 6 , wherein the separation member have a convex part, and the decompression path is formed between the separation member and the partition member. 
     
     
         10 . The heat exchanger according to  claim 6 , wherein the separation member is of a cylindrical shape, and the decompression path is formed within the separation member. 
     
     
         11 . The heat exchanger according to  claim 6 , further comprising a humidifier that mixes moisture discharged to the decompression path with air flowing through the air supply path and supplies the moisture to the target space. 
     
     
         12 . A heat exchanger comprising:
 an air supply path through which supply air supplied to a target space from outside of the target space passes;   an exhaust path through which exhaust air discharged from the target space to the outside of the target space passes;   a partition member that divides the air supply path and the exhaust path and performs heat exchange between the supply air and the exhaust air;   a separation member arranged at an air supply path side that adsorbs moisture in air or discharges adsorbed moisture to the air; and   a decompression path provided between the partition member and the separation member, divided from the air supply path by the separation member, and connected to a decompression pump,   wherein the air supply path, the exhaust path, and the decompression path each have a different air flow-in surface and air exhaust surface.   
     
     
         13 . A ventilator comprising the heat exchanger according to  claim 1 .
