Smart accumulator to scrub inlet fluid

Abstract

The Smart Accumulator Fluid Scrubbing System includes a drying mechanism and filtration system with liquid level control all in one housing to protect compressors or compressor systems from moisture, contaminants, and liquid ingestion. The Smart Accumulator is connected to the compressor or compressor systems inlet. The Smart Accumulator only allow dry, clean gas to enter the compressor and compressor system. The switch in conjunction with the heating elements and compressor circuits prevents the compressor from running, while heating elements boil off excess liquid. The Pressure equalizing port prevent compressor to start at high delta pressure and or reduces extremely high-pressure compressor or system operation that may be detrimental to mechanical failure.

Claims

Description

BRIEF DESCRIPTION OF THE DRAWINGS

(1) For a more complete understanding of the present invention and for further illustration of the design and advantages thereof, refer to the drawing in FIG. 1.

DETAILED DESCRIPTION

(2) Various components of the present invention will now be described more fully with reference to the accompanied drawings. The invention may, however, be embodied in many different forms and should not be constrained to the embodiment set forth herein.

(3) FIG. 1 illustrates a Smart Accumulator 200. In a typical system, the Smart Accumulator will be attached directly to the compressor housing by means of tubing or can be placed in the suction line.

(4) The Smart Accumulator 200 uses a heat conductive Housing 208 that is exposed to the ambient heat to assist evaporation of any refrigerant or volatile liquid.

(5) The Smart Accumulator uses heating Elements 210 attached to Housing 208. A Switch 209 is attached to the Housing 208. The Switch 209 triggers ON when the liquid level inside the Housing 208 increases above the set limit. The heating Elements 209 heats the liquid to evaporate.

(6) The inside of the Housing 208 has Brackets 207 which holds the Holder 221 of the Filter Assembly 218.

(7) The Housing 208 connects to port 214 to connect to high pressure chamber to Equalization or release high pressure when needed. The Pressure Equalizing port 214 can be connected with some valving to fluidly exchange flow from high to low pressure when needed, for compressors that cannot start at High to Low delta pressure or to lower compressor or system very high discharge pressure.

(8) The Housing 208 connects to an Intake Tube 213 with inlet port in close proximity to the top of the Top Cover 202 to ensure that only clean gas can enter the compressor and compressor system.

(9) The Intake Tube 213 is attached to a Valve 212 to prevent back flow in the event of compressor failure or during servicing the Smart Accumulator 200.

(10) The Intake Tube 213 provides a small Oil Hole 211 for oil to return to the compressor and compressor housing.

(11) The Inlet Tube 201 has Safety Flap 204, which opens only on positive set pressure by design. The Safety Flap 204 opens only when the Filter Assembly 218 is clogged which increases the positive pressure.

(12) The Filter Assembly 218 consists of Desiccant 216 which resides between the Perforated Partition 219 and 222 to remove moisture from the gas entering to Inlet Tube 201.

(13) The Filter Assembly 218 consists of filter material 215 which resides between the Perforated Partition 222 and 223 to remove contaminants from the gas entering from the Desiccant 216 assembly.

(14) The Filter Assembly 218 consists of Strainer Mesh 217 which further removes particles from the gas entering from the filter material 215 assembly. The Strainer Mesh 217 size depends on the minimum size of contaminants that are required to be filtered.

(15) The Sealing Plate 220 seals against the bracket 207 of the Filter Assembly 218.

(16) The Top Cover 202 is welded and screwed to housing 208 and to the Inlet Tube 201.

(17) The inlet Tube 201 is welded to top cover 202.

(18) The Funnel (205) is in operative connection with the filter.
