Minimal Waste Refrigerant Delivery Device

Abstract

A minimal waste refrigerant delivery device for delivering refrigerant to a vehicle's air conditioning system. The minimal waste refrigerant delivery device has a first end adapted to attach to a cannister of refrigerant and a second end adapted to be releasably coupled directly to the vehicle's air conditioning system charging port. A pressure measuring gauge is provided for measuring the pressure of the vehicle's air conditioning system when connected to the vehicle's charging port. The minimal waste refrigerant delivery device is specifically adapted to be coupled directly to the vehicle's servicing port thereby eliminating the need for a hose and minimizing the amount of refrigerant that is wasted when disconnecting the device from the vehicle's charging port. A valve actuator is provided to selectively allow or inhibit flow of refrigerant from the pressurized refrigerant container through the minimal waste refrigerant delivery device to the vehicle's charging system.

Description

CROSS-REFERENCE TO RELATED APPLICATIONS[0001]This application claims the benefit of U.S. Provisional Patent Application No. 62 / 772,832, filed on Nov. 29, 2018, which is incorporated herein in its entirety by reference.STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT[0002]Not ApplicableBACKGROUND OF THE INVENTION1. Field of Invention[0003]The invention relates to a device for delivering a refrigerant into an air conditioning system. More particularly, it relates to a device for delivering a refrigerant into the air conditioning system of a vehicle and that is adapted to be used without a hose so as to reduce the amount of refrigerant that is vented to the atmosphere during the steps of connecting and disconnecting the device.2. Description of the Related Art[0004]In the field of vehicles, such as, but not limited to automobiles, cars, trucks, and other types of motorized vehicles, it is known that that an air conditioning system removes humidity from, and cools, ambien...

AI Technical Summary

Benefits of technology

The present invention is a device that delivers refrigerant to a vehicle's air conditioning system without using a hose. The device has a pressure gauge to measure the pressure of the air conditioning system when connected to the vehicle's charging port. The device also has a valve actuator to control the flow of refrigerant from the refrigerant container to the vehicle's air conditioning system. This invention minimizes the amount of refrigerant that is wasted when disconnecting the device from the vehicle's charging port.

Problems solved by technology

It is known in the art that R-1234yf is flammable; and while the toxicity of R-1234yf is being debated, it is known that various of the gases formed by combustion of R-1234yf are toxic.

Further, other refrigerants, such as various mixtures of propane and butane have been formulated to replace refrigerants such as R-12 and R-134A due to the harmful effects of these refrigerants on the atmosphere.

Not only is this wasteful, it also has a detrimental impact on the atmosphere.

And, in the case of refrigerants such as R-1234yf, waste has an economic impact as R-1234yf is known to be significantly more expensive than refrigerants such as R-134A.
