Patent ID: 8285511

Claim:
A method for estimating a temperature of a test point in a space with air conditioning, the method comprising: deploying a first sensor device and a second sensor device in the space, wherein the second sensor device is deployed at the test point; calculating a plurality of state parameters and establishing a plurality of temperature transformation formulas according to a plurality of temperatures detected by the first and the second sensor devices and states of an air conditioner during a predetermined time period, wherein the temperature transformation formulas respectively corresponds to one of said states of the air conditioner; removing the second sensor device; determining a current state of the air conditioner according to a plurality of reference temperatures newly detected by the first sensor device and the state parameters, wherein the current state is one of said states of the air conditioner; selecting a temperature transformation formula corresponding to the current state from the temperature transformation formulas; and estimating a current temperature of the test point by using the selected temperature transformation formula and the reference temperatures.
