Benefits of technology

The patent text describes certain aspects of the invention in a brief way. This helps to explain the invention to people who are not familiar with it. The technical effects of the invention are not explained in detail here, but further information can be found by reading the claims of the patent.

Problems solved by technology

Unfortunately, this compression uses a significant amount of energy and relatively powerful motors that may be large and heavy may be used in order to compress the refrigerant quickly.
However, particularly in a portable refrigerant recovery unit, a heavy motor can negatively impact the portability, ease of use, and / or ease of storage.

Embodiment Construction

[0017]According to various embodiments described herein, an isolated piston compressor is provided that exhibits improved efficiency as compared to conventional compressors. For the purposes of this disclosure, the term, “isolated pistons” refers to pistons that have case chambers in fluid isolation from one another. The term, “case chamber” as used herein refers to a chamber disposed below the piston head. The isolated piston compressor is particularly suitable for use with a refrigerant recovery unit to service a refrigeration system. As used herein, the term, “servicing” refers to any suitable procedure performed on a refrigeration or air conditioning system such as, for example, recovering refrigerant, recharging refrigerant into the refrigeration system, testing refrigerant, leak testing the refrigeration system, recovering the lubricant, replacing the lubricant, and the like. An embodiment of the isolated piston compressor disclosed herein may be used to improve compressor per...

Abstract

A compressor includes a first piston, a second piston, and a crank. A first case chamber is defined by a lower surface of a first piston head, a portion of a first cylinder surface disposed below the lower surface of the first piston head, and a first case surface. A second case chamber is defined by a lower surface of a second piston head, a portion of a second cylinder surface disposed below the lower surface of the second piston head, and a second case surface. The first case chamber and the second case chamber are fluidly isolated from one another. The crank is to reciprocate the first piston head and the second piston head up and down.

Description

FIELD OF THE INVENTION[0001]The disclosure generally relates to a refrigerant recovery unit. More particularly, the disclosure relates to an improved compressor and method of utilizing the improved compressor in the refrigerant recovery unit.BACKGROUND OF THE INVENTION[0002]Portable refrigerant recovery units or carts are used in connection with the service and maintenance of refrigeration systems, such as a vehicle's air conditioning system. The refrigerant recovery unit connects to the air conditioning system of the vehicle to recover refrigerant out of the system, separate out oil and contaminants from the refrigerant in order to recycle the refrigerant, and recharge the system with additional refrigerant.[0003]During refrigerant recovery, the refrigerant recovery unit draws the refrigerant out of the air conditioning system or other such refrigeration system. The refrigerant is generally drawn out in vapor phase and is typically compressed by the refrigerant recovery unit and th...
