Title: Oil discharge protector for scroll compressor
Inventor: MA YEONG CHAN
IPC: F04C29/02
Filed: 1999-07-28
Abstract: PURPOSE: A device of a scroll compressor is provided to prevent excessive discharge oil via an outlet pipe by installing an oil gate making oil flow reversely at a specific height of a baffle when an oil pressure of an outlet pipe is over a specific level. CONSTITUTION: A baffle(53) has an upper hole(53a) for passing refrigerant gas and a lower hole(53b) for passing oil. An oil gate(57) opened and closed in one way is connected to the baffle by a hinge(58). A scroll compressor is operated by the rotation of a rotor whereto a rotary shaft is fitted by the electromagnetic force with a stator. According to the rotation of the rotary shaft, a slewing scroll slews around a fixed scroll and the refrigerant gas sucked via a suction pipe is compressed in a compressing chamber formed between the slewing scroll and the fixed scroll. The compressed air is discharged via an outlet formed in the fixed scroll and then discharged out of the compressor via an outlet pipe. If compression is performed excessively due to excessive rotation of the rotary shaft, oil gathers to the right of the baffle and the surface of the oil rises rapidly. If a height difference(hmax) is formed due to rapid elevation of the oil surface, the oil gate rotates by centering on the hinge and the oil gate is opened. The oil at the right of the baffle flows to the left through the oil gate thus the discharge of the oil out of the compressor is prevented.

Abstract: PURPOSE: A method for processing a soft handoff in a CDMA(Code Division Multiple Access) mobile communication system is provided to decide a type of a handoff call according to a progressing direction of a mobile station, when the mobile station exists in a present handoff area, and to process the handoff call according to the decided type, so as to suppress an unnecessary handoff call processing. CONSTITUTION: If a call is generated(S11), a CDMA mobile communication system retrieves whether the call is a handoff call(S12). If the call is a new call, the system retrieves the number of usable channels(S13). If usable channels do not exist, the system allocates a traffic channel to the call(S14). If the call is the handoff call, the system confirms a channel occupation state(S16). If an occupation rate of the traffic channel is below 90 percent, the system processes the call(S17). If the occupation rate is over 90 percent, the system searches a position of an MS(Mobile Station)(S18). The system checks the position(S19). If the MS is far from a target base station, the system decides the handoff call as a spurious handoff call(S23), and removes the handoff call(S24). If the call is decided as a real handoff call(S20), the system retrieves the number of usable channels(S21). If the usable channels do not exist, the system removes the handoff call(S24). If the usable channels exist, the system stands by the handoff call(S22).

Abstract: PURPOSE: A tube structure for evaporative heat exchanger is provided to achieve an enhanced heat transfer performance and phase change result by decreasing the dead region formed in the tube. CONSTITUTION: A tube(122) penetrating each fin(121) of an evaporative heat exchanger(120) is shaped as an ellipsoid having a larger diameter in the air and water flow direction. The tube has a longer side the diameter of which is 1.5 to 3 times larger than that of a shorter side. Upon start of the air conditioner, refrigerant flows through the tube of the evaporative heat exchanger. Then, the fan mounted onto the outdoor unit rotates, to thereby allow the air to flow from the lower portion toward the upper portion of the evaporative heat exchanger. The water is pumped from the water tank, and ejected from the upper portion toward the lower portion of the evaporative heat exchanger. The air and vapor passing through the heat exchanger collide against the tube of the heat exchanger. Since the tube is shaped as an ellipsoid having a larger diameter in the air and water flow direction, the resistance caused by the collision of the air and vapor against the tube is decreased.
