| An oil-flooded screw compressor drives a pair of rotors at a rotational speed which is low enough not to increase torque for a short amount of time after start-up and accelerates the pair of rotors up to a normal-operation rotational speed after oil discharge. Alternatively, the oil-flooded screw compressor rotates the pair of rotors for a short amount of time after the remaining compressed gas is discharged after a halt, thereby allowing the oil accumulated inside the working chambers to be discharged and ensuring smooth start-up after the halt. | ||||||

| 46 | System and method for performing cooling | US836656 | 1997-05-16 | US5732560A | 1998-03-31 | Erik Thuresson; Henrik Ohman |
| The invention relates to a refrigeration system of the air cycle cooling system type, also called reversed Brayton cycle in which the air flow through compressor means (12, 16), heat exchanger means (24) for withdrawal of heat from the compressed air and finally expander means (22) from where it is delivered to perform cooling. According to the invention the system includes heat load means (41) having a large flow resistance, creating a considerable over-pressure at the expander outlet (23). A rotary screw machine is included in the expander (22) and also in the compressor means (12, 16), which latter screw rotor machine (12) is driven solely by the screw rotor machine (22) of said expander means. A screw rotor machine (16) connected in parallel with the screw rotor machine (12) of said compressor means is driven separately, preferably by a drive engine (19), the rotational speed of which si controlled by pressure sensing means (36) in a conduit between the expander outlet (23) and an inlet to the heat load means (41), and thereby--via said expander means--also drive the velocity of the screw rotor machine (12) of said compressor means. The system is particularly intended for cooling the electronic equipment in air-craft when being on the ground. | ||||||

| PURPOSE: To protect a compressor by preventing the temperature increase at the bearing due to lubrication oil deficiency by detecting the rotational speed and bearing temperature of the compressor as well as the room temperature to determine the presence or lack of the bearing seizure of the compressor so as to control the frequency of the compressor. CONSTITUTION: The bearing temperature is detected by a bearing temperature detecting means 10 of a compressor, and the room temperature is detected by a room temperature detecting means 12. These detected values are inputted to a compressor control device 11 to convert the power source to a desired frequency to drive the compressor 2. After determining whether or not the compressor operating frequency is disregarded, and its frequency is modulated to the safer side if the temperature is outside the safety tolerance, that is, if it was operating at too high a speed, the frequency is reduced to the lower speed side by a certain decrement. In this manner, the bearing temperature is prevented from rising. COPYRIGHT: (C)1987,JPO&Japio | ||||||

| <P>PROBLEM TO BE SOLVED: To solve problems wherein, when starting an oil-cooled screw compressor after a long time stop in cold environment, starting torque is increased by a rise in viscosity of oil accumulated in a working chamber and a driving means with a capacity larger than required in normal operation is required. <P>SOLUTION: The oil-cooled screw compressor is provided with a casing, a pair or rotors housed in the casing and having a threaded tooth groove, an electric motor for rotating and driving the rotors, a control device for controlling the electric motor, an oil supply mechanism for supplying the oil to the working chamber surrounded by the rotor and the casing by meshing the tooth grooves of the pair of the rotors, and an oil separating mechanism for separating the oil from compressed gas delivered from the working chamber. Only in a short time just after starting, driving is performed in a low speed not enlarging torque and the oil is delivered, and then, the speed is increased to the ordinary operation speed. Alternatively, the residual pressure is released after stopping, and then, the rotor is rotated for a short time, and thereby, the oil accumulated in the working chamber is delivered, and the next starting is lightened. <P>COPYRIGHT: (C)2010,JPO&INPIT | ||||||
