the air conditioner control module stores the ambient temperature, the heating set temperature and the lowest heating temperature of the air conditioner and compares the ambient temperature, the heating set temperature and the lowest heating temperature of the air conditioner; if the environment temperature is lower than the lowest heating temperature of the air conditioner and the heating set temperature is not lower than the lowest heating temperature of the air conditioner, the air conditioner control module sets the temperature of the air conditioner to be consistent with the heating set temperature, and the air conditioner controls the starting and stopping of heating by a program of the air conditioner; if the ambient temperature is lower than the lowest heating temperature of the air conditioner, and the heating setting temperature is between the lowest heating temperature of the air conditioner and the current ambient temperature, the air conditioner control module controls the air conditioner to start heating, and when the ambient temperature is increased to be consistent with the heating setting temperature, the air conditioner control module controls the air conditioner to stop heating.
6. The control device for expanding the temperature adjustment range of an air conditioner according to claim 5, wherein the heating installation temperature is a temperature range fluctuating up and down.
7. The control device for expanding the temperature adjustment range of the air conditioner as claimed in claim 5, wherein the air conditioner control module is connected with the air conditioner through wired communication or wireless communication.
8. A control method for expanding the temperature adjusting range of an air conditioner is characterized by comprising the following steps:
acquiring the ambient temperature and the highest refrigerating temperature of an air conditioner;
setting a refrigeration set temperature;
if the environment temperature is higher than the highest refrigeration temperature of the air conditioner and the refrigeration set temperature is not higher than the highest refrigeration temperature of the air conditioner, setting the temperature of the air conditioner to be consistent with the refrigeration set temperature, and controlling the start and stop of refrigeration by the program of the air conditioner;
and if the ambient temperature is higher than the highest refrigeration temperature of the air conditioner, and the refrigeration set temperature is between the highest refrigeration temperature of the air conditioner and the current ambient temperature, controlling the air conditioner to start refrigeration, and when the ambient temperature is reduced to be consistent with the refrigeration set temperature, controlling the air conditioner to stop refrigeration.
9. The method for expanding the temperature adjustment range of an air conditioner according to claim 8, wherein the control method further comprises:
acquiring the lowest heating temperature of the air conditioner;
setting a heating set temperature;
if the environment temperature is lower than the lowest heating temperature of the air conditioner and the heating set temperature is not lower than the lowest heating temperature of the air conditioner, setting the temperature of the air conditioner to be consistent with the heating set temperature, and controlling the starting and stopping of heating by a program of the air conditioner;
and if the ambient temperature is lower than the lowest heating temperature of the air conditioner and the heating set temperature is between the lowest heating temperature of the air conditioner and the current ambient temperature, controlling the air conditioner to start heating, and when the ambient temperature is increased to be consistent with the heating set temperature, controlling the air conditioner to stop heating.
10. A control method for expanding the temperature adjusting range of an air conditioner is characterized by comprising the following steps:
acquiring an ambient temperature and the lowest heating temperature of an air conditioner;
setting a heating set temperature;
if the environment temperature is lower than the lowest heating temperature of the air conditioner and the heating set temperature is not lower than the lowest heating temperature of the air conditioner, setting the temperature of the air conditioner to be consistent with the heating set temperature, and controlling the starting and stopping of heating by a program of the air conditioner;
and if the ambient temperature is lower than the lowest heating temperature of the air conditioner and the heating set temperature is between the lowest heating temperature of the air conditioner and the current ambient temperature, controlling the air conditioner to start heating, and when the ambient temperature is increased to be consistent with the heating set temperature, controlling the air conditioner to stop heating.
