Device for saving power consumption of heating and air conditioning system

Abstract

A device for saving power consumption of heating and air conditioning system is provided. The energy saving device is adapted to automatically stop an air conditioner when outdoor temperature is lower than a set temperature or automatically stop a heater when outdoor temperature is higher than a set temperature. The energy saving device is provided with an outdoor temperature sensor and converter for measuring an outdoor temperature and converting the measured temperature into a first voltage value, a conversion circuit for converting a set temperature of stopping the air conditioner/heater into a second voltage value, a control circuit for controlling the air conditioner/heater, and a comparison circuit for comparing the first voltage value with the second voltage value and transmitting the result to the control circuit.

1 . An energy saving device for a heating and air conditioning system comprising at least:
 an air conditioner;   an outdoor temperature sensor and converter for measuring an outdoor temperature and converting the measured temperature into a first voltage value;   a conversion circuit for converting a set temperature of stopping the air conditioner into a second voltage value;   a control circuit for controlling the air conditioner;   a comparison circuit for comparing the first voltage value with the second voltage value and transmitting the result to the control circuit;   wherein the control circuit will control the air conditioner to continue its operation if the outdoor temperature is higher than the set temperature of stopping the air conditioner in response to the comparison resulted transmitted from the comparison circuit and the control circuit will stop the air conditioner if the outdoor temperature is equal to or lower than the set temperature of stopping the air conditioner in response to the comparison result transmitted from the comparison circuit.   
   
   
       2 . An energy saving device of  claim 1 , further comprising one or more fan, wherein the one or more fan is disabled while the air conditioner is continuously actuated, and actuated by the control circuit while the air conditioner is stopped to operate so as to maintain the room temperature at the set temperature of the air conditioner in response to stop of the air conditioner. 
   
   
       3 . An energy saving device of  claim 1 , further comprising one or more electric window, wherein the one or more electric window is closed while the air conditioner is continuously actuated, and opened by the control circuit for ventilation in response to the air conditioner being stopped. 
   
   
       4 . An energy saving device of  claim 1 , further comprising one or more fan and one or more electric window, wherein the one or more fan is disabled and the one or more electric window is closed while the air conditioner is continuously actuated, and the one or more fan is actuated and the one or more electric window is opened by the control circuit for ventilation while the air conditioner is stopped to operate so as to maintain the room temperature at the set temperature of the air conditioner in response to the air conditioner being stopped. 
   
   
       5 . An energy saving device for a heating and air conditioning system comprising at least:
 a heater;   an outdoor temperature sensor and converter for measuring an outdoor temperature and converting the measured temperature into a first voltage value;   a conversion circuit for converting a set temperature of stopping the heater into a second voltage value;   a control circuit for controlling the heater;   a comparison circuit for comparing the first voltage value with the second voltage value and transmitting the result to the control circuit;   wherein the control circuit will control the heater to continue its operation if the outdoor temperature is lower than the set temperature of stopping the heater in response to the comparison resulted transmitted from the comparison circuit and the control circuit will stop the heater if the outdoor temperature is equal to or higher than the set temperature of stopping the heater in response to the comparison result transmitted from the comparison circuit.   
   
   
       6 . An energy saving device of  claim 5 , further comprising one or more electric window, wherein the one or more electric window is closed while the heater is continuously actuated, and opened by the control circuit for ventilation in response to the air conditioner being stopped.
