    • A method and apparatus of controlling an air conditioner. The discharge temperature of a compressor and the indoor heat exchanger temperature are steadily controlled to set temperatures as close as possible, suppressing hunting of the frequency of an inverter. A temperature sensor is provided for detecting the temperature of the indoor heat exchanger or the discharge temperature of the compressor. A control unit is further provided, and judges as to in which temperature zone among at least preset four temperature zones the detected temperature is. Then, the control unit outputs frequency control signals to the inverter to perform the following operations: when the detected temperature is in the lowest temperature zone, the output frequency of the inverter is increased at a predetermined speed; in a lower intermediate temperature zone the frequency is slowly increased; in an upper intermediate temperature zone below a set temperature the current frequency is maintained; and in a temperature zone above the set temperature the frequency is decreased at a predetermined speed.

    • Provided is a catalyst for adding a glycidyl ether to an active hydrogen-containing organic compound, comprising a complex oxide of magnesium and at least one element other than magnesium selected from the group consisting of the elements in the third period and the fourth period in the periodic table. Also provided is a process for producing a glycidyl ether adduct, which comprises subjecting an active hydrogen-containing organic compound and a glycidyl ether to an addition reaction in the presence of the above-mentioned catalyst. In the addition reaction between the active hydrogen-containing organic compound and the glycidyl ether, use of the catalyst of the present invention enables inhibition of an excess addition reaction of the glycidyl ether which is a successive reaction, and a mono- or di-(alkyl, alkenyl or phenyl) ether product in which one or two glycidyl ethers are added is selectively produced by adjusting the mole ratio of the active hydrogen-containing organic compound to the glycidyl ether to a specific range. Accordingly, the mono- or di-(alkyl, alkenyl or phenyl) ether product can be obtained at a high productivity with a high purity.
