Hetro dehumidifier

Abstract

The present invention relates to hetro dehumidifier for controlling the humidity in a room. The hetro dehumidifier controls the humidity by using combination of heaters and air conditioner. The dehumidifier of the present invention includes heaters, air conditioner, air circulation fans, humidity sensors, temperature sensors, air filters, digital display & front panel keys, microcontroller and IR Remote control.

1 . A dehumidifier for controlling the humidity in a room, the dehumidifier comprising:
 a) at least one heater for heating the air in the room;   b) at least one air conditioner for cooling the air in the room;   c) at least one air circulation fan for circulating the air in the room;   d) at least one temperature sensor for sensing the temperature in the room;   e) at least one humidity sensor for sensing the humidity in the room;   f) at least one control circuit for controlling the heater based on temperature and humidity sensor readings;   wherein the humidity of the room is controlled by air circulation from the combined action of the heater and air conditioner.   
     
     
         2 . The dehumidifier as claimed in  claim 1 , wherein the heaters will turn ON when the room humidity is more than the set humidity of the room. 
     
     
         3 . The dehumidifier as claimed in  claim 1 , wherein when the room temperature is increased beyond the set temperature of the room the air conditioner turns ON and cools the room. 
     
     
         4 . The dehumidifier as claimed in  claim 1 , wherein the heater and the air conditioner act in combination to achieve the set humidity in the room. 
     
     
         5 . The dehumidifier as claimed in  claim 1 , wherein the Air handling unit (AHU) and Air conditioner unit function in connection to maintain the desired set temperature and set humidity in the room. 
     
     
         6 . The dehumidifier as claimed in  claim 1 , wherein the heater acts in combination with the humidity sensor to control the humidity in the room. 
     
     
         7 . The dehumidifier as claimed in  claim 1 , wherein the dehumidifier further comprises
 a) Digital display;   b) Front panel with keys;   c) Microcontroller;   d) EEPROM;   e) IR remote control;   f) Pre air filters;   g) Provision for connections to duct;   h) Provision for wall mounting;   
     
     
         8 . A method of controlling the humidity in a room, the method comprising the combined action of the heater and air conditioner to achieve the set humidity in the room. 
     
     
         9 . The method as claimed in  claim 8 , wherein when the room humidity is more than the set humidity, the heater turns ON and increases the temperature of the room. 
     
     
         10 . The method as claimed in  claim 8 , wherein the air conditioner turns ON when the room temperature is more than the set temperature of the room.
