Benefits of technology

This patent describes a rotary compressor with a built-in control unit that regulates the speed at which refrigerant is injected into the compressor. This control is achieved by using an electromagnetic coil that is installed on the compressor and works by alternating between suction and compression of the refrigerant. The purpose of this invention is to improve the performance of air conditioning systems by controlling the circulation of refrigerant, preventing rotary compressor restarts which can save energy and improve maintenance.

Problems solved by technology

However, such inverter compressor uses an electrical frequency method, which is technologically complicated, expensive, and difficult to repair.

first embodiment

[0034]According to FIG. 5, the installation of the electromagnetic coil 10 onto the rotary compressor in the first embodiment to control the opening and closing of the vane 4 is further described as follows:

[0035]The rotary compressor (as shown in FIG. 1) is bored horizontally to make a hole that is at the same level of and perpendicular to the vane 4. This hole passes through a shield 17 and the cylinder block 3 of the rotary compressor until it reaches the slot 5 where the vane 4 is installed. The size of the hole is small enough for the armature core 15 to move back and forth fitly. Then, the vane 4 is pressed into the slot 5 entirely and an area where the bored hole intersects with the vane 4 is to be observed. A mortise is then formed on this particular area of the vane 4 (as shown in FIG. 7). Then, the electromagnetic coil 10 (as shown in FIG. 3) is installed at the bored hole and welded firmly at the joint of a flange 19 (Shape may differ according to the surface of the piece...

second embodiment

[0039]According to FIG. 9, the electromagnetic coil, which has the same structure and function as shown in FIG. 3 and FIG. 4, but the armature core 15 of which is shorter, and the shape of the flange 19 of which differs depending on the surface of the piece on which it is to be installed, is used for installation on the rotary compressor in the second embodiment to control the opening and closing of the vane 4.

[0040]According to FIG. 10 and FIG. 11, a conventional rotary compressor is connected to a connection arm 20 from the vane 4. The size of the arm 20 must be at the right size to allow insertion through the spring 21 and past the shield 17 of the rotary compressor and it should be long enough to enable installation of the electromagnetic. A tube 22 is then used to cover the arm 20 inside of which a bushing 23 supports the arm 20 to provide stability and to ensure that the arm 20 is not detached from a bushing 23 at all times even when the vane 4 slides into the piston chamber 9...

Abstract

This rotary compressor with an installed circulation control unit utilizes a method to control a rotary compressor to start or stop injecting refrigerant at a predetermined velocity by means of an electromagnetic coil that is installed onto the rotary compressor. The end of the electromagnetic coil is tenon-shaped and enters into a mortise that is formed on a vane or an arm of the rotary compressor so that the operation alternates between suction and compression at a predetermined period, enabling control of the rate of refrigerant circulation. In addition, the rotary compressor does not restart during its operation, which enhances the performance of the air-conditioning system, saves costs and energy, and enables the air-conditioning system to be easily maintained and repaired.

Description

FIELD OF INVENTION[0001]The present invention relates to a rotary compressor and more particularly to a rotary compressor with an installed circulation control unit.BACKGROUND OF THE INVENTION[0002]An inverter air conditioning system is an air conditioning system the capacity of which is controlled by the volume of refrigerant circulation resulting from controlling the cycle speed of its compressor. However, such inverter compressor uses an electrical frequency method, which is technologically complicated, expensive, and difficult to repair.[0003]Therefore, this rotary compressor with an installed circulation control unit disclosed under this patent application is developed to solve the above problems with its system being less complicated, economical, and easy to repair.SUMMARY OF THE INVENTION[0004]This rotary compressor with an installed circulation control unit utilizes a method to control a rotary compressor to start or stop injecting refrigerant at a designated velocity by mea...
