Dehumidification system

Abstract

A dehumidification system according to an exemplary embodiment of the inventive concept performs dehumidification of indoor air without power waste and condensation heat by transferring water molecules of indoor air to the outdoor air through a porous separation membrane filter, thereby minimizing energy consumption. Also, the dehumidification system may perform dehumidification without outdoor air flow into the indoor space, which prevents indoor air temperature change due to outdoor air and inflow of pollutants like fine dust included in outdoor air.

What is claimed is: 
     
         1 . A dehumidification system comprising:
 an indoor air circulation path entering indoor air and then discharge the same to the indoor space to circulate;   an outdoor air circulation path entering outdoor air and then discharge the same to the outdoor space to circulate;   a porous separation membrane filter installed between the indoor air circulation path and the outdoor air circulation path and passes water molecules included in the indoor air passing through the indoor circulation path to the outdoor air circulation path.   
     
     
         2 . The dehumidification system of  claim 1 , wherein the system further includes an indoor air circulation fan installed near the outlet of indoor air exhausting the indoor air to the indoor space in the indoor air circulation path and an outdoor air circulation fan installed near the outlet of outdoor air exhausting the outdoor air to the outdoor space in the outdoor air circulation path. 
     
     
         3 . The dehumidification system of  claim 2 , wherein the speed of spinning of the outdoor air circulation fan is set to be faster than the one of the indoor air circulation fan. 
     
     
         4 . The dehumidification system of  claim 1 , wherein the system further includes an indoor air damper installed in the indoor air circulation path and controlling the amount of air flow passing through the indoor air circulation path. 
     
     
         5 . The dehumidification system of  claim 4 , wherein the system further includes an outdoor air damper installed in the air circulation path and controlling the amount of air flow passing through the outdoor air circulation path. 
     
     
         6 . The dehumidification system of  claim 2 , wherein the system further includes a sensor measuring the humidity of indoor air and a control unit operating the indoor air circulation fan and the outdoor air circulation fan when the humidity measured in the sensor is higher than the premeasured reference humidity. 
     
     
         7 . The dehumidification system of  claim 6 , wherein the control unit stops the operation of the indoor air circulation fan and the outdoor air circulation fan when the humidity measured by the sensor is lower than the premeasured reference humidity. 
     
     
         8 . The dehumidification system of  claim 1 , wherein the porous separation membrane filter includes a plurality of holes whose sizes are smaller than the sizes of nitrogen (N2), oxygen (O2), and carbon dioxide (CO2) molecules included in the indoor air and larger than the size of the water molecule. 
     
     
         9 . The dehumidification system of  claim 1 , wherein the indoor air circulation path and the outdoor air circulation path are divided by the porous separation membrane filter. 
     
     
         10 . A dehumidification system comprising:
 an indoor air circulation path entering indoor air and then discharge the same to the indoor space to circulate;   an outdoor air circulation path entering outdoor air and then discharge the same to the outdoor space to circulate;   a porous separation membrane filter installed between the indoor air circulation path and the outdoor air circulation path and passes water molecules included in the indoor air passing through the indoor circulation path to the outdoor air circulation path;   an indoor air circulation fan installed near the outlet of indoor air exhausting the indoor air to the indoor space in the indoor air circulation path;   an outdoor air circulation fan installed near the outlet of outdoor air exhausting the outdoor air to the outdoor space in the outdoor air circulation path;   an indoor air damper installed in the indoor air circulation path and controlling the amount of air flow passing through the indoor air circulation path; and   an outdoor air damper installed in the outdoor air circulation path and controlling the amount of air flow passing through the outdoor air circulation path.   
     
     
         11 . A dehumidification system comprising:
 an indoor air circulation path entering indoor air and then discharge the same to the indoor space to circulate;   an outdoor air circulation path entering outdoor air and then discharge the same to the outdoor space to circulate;   a porous separation membrane filter installed between the indoor air circulation path and the outdoor air circulation path and passes water molecules included in the indoor air passing through the indoor circulation path to the outdoor air circulation path;   an indoor air circulation fan installed near the outlet of indoor air exhausting the indoor air to the indoor space in the indoor air circulation path;   an outdoor air circulation fan installed near the outlet of outdoor air exhausting the outdoor air to the outdoor space in the outdoor air circulation path;   an indoor air damper installed in the indoor air circulation path and controlling the amount of air flow passing through the indoor air circulation path;   an outdoor air damper installed in the outdoor air circulation path and controlling the amount of air flow passing through the outdoor air circulation path;   a sensor measuring the humidity of indoor air; and   a control unit controlling the degree of openness of the indoor air damper and the outdoor air damper according to the humidity measured by the sensor and the speed of spinning of the outdoor air circulation fan to be faster than the one of the indoor air circulation fan.
