A humidor heat exchanger system and method for using thereof to control temperature and relative humidity are disclosed. The humidor heat exchanger system comprises two or more processors coupled to one or more memories, one or more communication interfaces, one or more thermoelectric modules, one or more compressors, one or more heaters, two or more LEDs, one or more fans, one or more sensors, one or more displays, one or more water collectors, one or more doors, one or more water reservoirs, and one or more evaporators. The two or more processors are communicatively connected to the one or more thermoelectric modules, one or more compressors, one or more heaters, two or more LEDs, one or more fans, one or more sensors, one or more displays, one or more water collectors, one or more doors, and one or more water reservoirs, and one or more evaporators. The two or more processors of the humidor heat exchanger system are configured to control temperature and relative humidity of a humidor by: detecting temperature in the one or more thermoelectric modules; detecting temperature in the one or more evaporators; checking temperature difference between the one or more thermoelectric modules and the one or more evaporators; calculating average temperature value in the one or more thermoelectric modules as to not force the one or more compressors to operate outside a safety region and not be powered on before the necessary period of time to balance cooling circuit pressure; activating the one or more compressors depending on the temperature difference between the one or more thermoelectric modules and the one or more evaporators; dynamically adjusting temperature control parameters as a function of adjusted temperature variation conditions; initiating relative humidity control; checking output of the one or more thermoelectric modules; adjusting power output of the one or more thermoelectric modules to attain desired relative humidity value; and stabilizing relative humidity exactly to the value adjustment made without oscillating about 1%.
