Embodiment Construction

[0015] According to various embodiments described herein, a refrigerant recovery system is provided to facilitate servicing of refrigeration systems. As used herein, the term "service" refers to any suitable process performed on a refrigeration system, such as recovering refrigerant, testing refrigerant, leak testing of a refrigeration system, recharging a refrigeration system, purging refrigeration agent to remove impurities, recycle lubricating oil, change lubricating oil, or similar processes. In one embodiment, the refrigerant recovery system disclosed herein can be used to recover contaminated refrigerant. In this or other embodiments, the refrigerant recovery systems described herein can recover such contaminated refrigerant without intermixing the contaminated refrigerant with clean refrigerant. In this or other embodiments, the refrigerant recovery systems described herein can recover such contaminated refrigerant without exposing the contaminated refrigerant to poten...

Abstract

A refrigerant recovery system includes a recovery apparatus and a refrigerant recovery unit. The recovery apparatus includes a heat sink, a capture tank, and a hose. The capture tank is in thermal contact with the heat sink. The capture tank is configured to capture a first refrigerant from a refrigeration system. The hose is to fluidly connect the capture tank to the refrigerant system. The refrigerant recovery unit includes a refrigerant storage unit, a refrigerant circuit, a processor and a memory. The refrigerant storage unit is configured to store a second refrigerant. The refrigerant circuit is in fluid connection with the heat sink. The refrigerant circuit is configured to circulate the second refrigerant through the heat sink, a compressor, and a condenser. The processor is configured to control the refrigerant recovery unit. The memory is to store diagnostic software and operating software to operate the refrigerant recovery unit.

Description

technical field [0001] The present invention generally relates to a refrigerant recovery unit. More particularly, it relates to an improved refrigerant recovery unit that collects a higher percentage of refrigerant from a refrigeration system than conventional refrigerant recovery units. Background technique [0002] Portable refrigerant recovery units or recovery vehicles are used in connection with the repair and maintenance of refrigeration systems, such as the air conditioning system of a vehicle. The refrigerant recovery unit is connected to the vehicle's air conditioning system to recover refrigerant from the system, separate oil and impurities from the refrigerant to recirculate the refrigerant, and recharge the system with additional refrigerant. [0003] Vehicle data such as vehicle make, make and model is manually entered into the refrigerant recovery unit to properly service the vehicle. Spending time entering vehicle information is inefficient and information c...
