Abstract:
The present invention relates to a reception antenna structure of a tire pressure monitoring system. The reception antenna is implemented using a cable-type antenna connected to a receiver of the tire pressure monitoring system. The cable-type antenna enables a mounting position of the antenna to be freely changed and improves a reception rate for measured data about temperature and pressure of a tire, that is modulated into data in the UHF band and transmitted to the outside of the tire in a wireless manner by a transmitter. According to the present invention, the reception antenna of a tire pressure monitoring system is implemented using a radiating leakage coaxial cable so as to enable the position of the antenna to be freely changed, so that, when tire pressure data is measured by a temperature and pressure sensor included in the transmitter within the tire and then transmitted through a tire pressure monitoring transmitter in a wireless manner, the reception sensitivity for the measured data is improved, thus increasing the reliability of the data measured at the tire, and guaranteeing the stability of the tire on the basis of the reliability of the reception sensitivity for the measured data.

A method for controlling an operation of an air conditioner having an inverter compressor and a regular velocity compressor includes: setting an upper limit threshold and a lower limit threshold based on a desired temperature set by a user, measuring a room temperature and comparing the measured room temperature and the set upper or lower limit threshold; and resetting the upper and lower limit thresholds based on a body adaptation time according to the comparison result, varying an operation frequency of a compressor and operating the compressor in the varied operation frequency for a predetermined time.
Abstract:
Disclosed is a method for controlling an air conditioner having a multi-compressor capable of improving an ability that corresponds to a room cooling load or a room heating load and capable of reducing an energy loss of the air conditioner. To this end, a compressing capacity of compressors by a temperature difference between a previous room temperature and a desired temperature predetermined by a user is pre-stored. Then, the pre-stored compressing capacity is varied on the basis of a temperature difference between a present room temperature and the desired temperature.
