Abstract: PURPOSE: A control method of an expansion valve is provided to obtain the optimum cooling efficiency by adjusting expansion valves exactly with precision depending on set temperatures of each indoor space. CONSTITUTION: A control unit detects temperatures of the central area and the lower area of a bypass heat transfer pipe under PID(Proportional Integral Differential) control. The overheating degree of refrigerant is calculated based on the detected temperatures. The overheating degree of refrigerant has a relatively large value for the bypass heat transfer pipe has large pipe resistance. A large amount of refrigerant is evaporated when the refrigerant flows through the bypass heat transfer pipe. Thereby, temperature difference between the central area and the lower area of the bypass heat transfer pipe is increased, and the overheating degree of refrigerant rises up. The control unit adjusts the opening of expansion valves depending on the calculated value. The expansion valves are controlled exactly with fineness by obtaining a relatively large opening degree.

Abstract: PURPOSE: An electromotive control valve is provided to minimize the difference of the position of a rotor at a state of which a rotary coil is moved to the bottom of a circular screw and reference position without regard to the position of a screw thread. CONSTITUTION: A rotary coil(166) is placed at the bottom of a circular screw(162) by rotating the rotary coil when assembling a rotor(130) to a valve body(110). A core shaft(132) of the rotor is combined to a guide. The rotor is rotated until a needle(140) closes an orifice(116) completely. Then the rotor is rotated once more. Thereafter, a compressed coil spring(152) is compressed so that one pitch, 0.5mm of gap between a hanging sill(133) of the core shaft and another hanging sill(142) of the needle is formed on a guide(118). Thereby the closing force about the orifice of the needle is improved.
