Abstract
Description
- The present application claims the benefit under Section 119(e) of the provisional application filed on Dec. 21, 2008 and assigned application No. 60/871,267.
- The present invention relates generally to air conditioning systems and specifically to an applicator for injecting an air conditioning system treatment into the system's coolant path.
- An air conditioning system provides a cooing effect according to a closed thermal refrigeration cycle. As illustrated in
FIG. 1 , anair conditioning system 10 comprises three primary components, acompressor 14, acondenser 18 and anevaporator 22 interconnected bypipes 26 carrying a refrigerant. The refrigerant alternates between a liquid state and a gas state as it circulates through a high-pressure section and a low-pressure section of thesystem 10. - A pressurized liquid refrigerant, such as Freon, enters the
evaporator 22 via anexpansion valve 32 that lowers the liquid pressure, allowing the refrigerant to vaporize (boil) at a lower temperature, thus ensuring that the refrigerant absorbs a maximum quantity of heat as it passes through the evaporator coif. As the reduced-pressure, liquid absorbs heat from the air (the cold refrigerated space) surrounding theevaporator 22 the refrigerant temperature reaches its boiling point and evaporates to a gas. - From the
evaporator 22, the low-pressure gas flows to thecompressor 14 where the gas is compressed to a high-pressure state. The higher pressure permits the gas to give up more heat (than a lower pressure gas), ensuring that the gas condenses to a liquid state during the next stage (condenser) of the refrigerate cycle. From thecompressor 14, the pressurised gas enters thecondenser 18 where the gas condenses to a high-pressure liquid, giving up heat to the warm environment surrounding thecondenser 18. The refrigerant then returns to theevaporator 22 via theexpansion valve 32 as a low pressure liquid. - An electric motor or an internal combustion engine (not shown) supplies fee mechanical rotational energy required to operate the
compressor 14 to compress the vapor and circulate the refrigerant Power consumed by theair conditioning system 10 is directly related to the energy required to operate thecompressor 14 and in turn related to compressor Motional forces that must be overcome by the electric motor or the internal combustion engine. Higher frictional forces raise the power consumption of thecompressor 14. Generally, a lubricating oil is added to the system to circulate with the refrigerant to reduce these frictional forces. - The present invention can be more easily understood and the advantages and uses thereof more readily apparent when the following detailed description of the present invention is read in conjunction with the figures wherein:
-
FIG. 1 illustrates a prior art air conditioning system. -
FIG. 2 illustrates an applicator of the present invention for loading an air conditioning system treatment into the air conditioning system ofFIG. 1 . -
FIG. 3 illustrates elements associated with a process for loading the treatment into an air conditioning system. -
FIG. 4 illustrates elements associated with a process for loading the treatment into the applicator of the present invention. -
FIGS. 5 and 6 illustrate another embodiment of an end cap for use with the applicator ofFIG. 2 . - In accordance with common practice, the various described device features are not drawn to scale, but are drawn to emphasize specific features relevant to the invention. Like reference characters denote like elements throughout the figures and text.
- Before describing in detail the exemplary methods and apparatuses related to an air conditioning system treatment applicator, it should be observed that the present invention resides primarily in a novel and non-obvious combination of elements and process steps. So as not to obscure the disclosure with details that will be readily apparent to those skilled in the art, certain conventional elements and steps have been presented with lesser detail, while the drawings and the specification describe in greater detail other elements and steps pertinent to understanding the invention.
- The following embodiments are not intended to define limits as to the structure or method of the invention, but only to provide exemplary constructions. The embodiments are permissive rather than mandatory and illustrative rather than exhaustive.
- An air conditioning system treatment is described in a co-pending and co-owned patent application entitled Air Conditioning System Treatment filed on Nov. 16, 2006 and assigned application Ser. No. 11/560,506. which is hereby incorporated by reference.
- The system treatment described in the patent application is loaded into an air conditioning system, such as the prior art
air conditioning system 10 ofFIG. 1 , using anapplicator 100 as illustrated inFIG. 2 . Theapplicator 100 comprises a hollowelongated reservoir 104, such as a tubular member, carrying the air conditioning system treatment. In one embodiment the reservoir holds about 6.5 ounces of treatment. The process of loading the treatment into thereservoir 100 is described below. Each end of thereservoir 104 is dosed by anend cap end cap 108/110 further comprises afitting 112 for connecting theapplicator 100 to an existing air conditioning system for adding the treatment within thereservoir 104 to the system's refrigerant path. Afitting cap 114 is removably affixed to eachfitting 112. -
FIG. 3 illustrates the elements associated with dispensing the air conditioning treatment from theapplicator 100 to an air conditioning system, such as theair conditioning system 10 ofFIG. 1 . Each fitting 112 (not visible inFIG. 3 ) removably receives a first end of ahose hose 126A is connected to a normally-closedSchrader valve 122A (referred to as an air conditioning system service port) at the high pressure outlet of thecompressor 14. Typically the high-side pressure is about 155 psi. A second end of thehose 126B is connected to a normally-closed Schrader valve 1228 at the low pressure inlet (or low side having a pressure of about 65 psi) of thecompressor 14. Thus as can be seen, thereservoir 104 is connected across the compressor inlet and outlet ports. Eachhose valve 130 for controlling the low of fluid therethrough. Only onevalve 130 is required according to the present invention. - The operation of connecting each
hose 126A/126B to itsrespective valve 122A/122B actuates a condition-controlling pin that opens thevalve 122A/122B. The technician then purges the hoses 126 of air according to techniques known in the art. The technician opens the shut-offvalves 130, permitting the air conditioning refrigerant to flow from thevalve 122A (the high pressure side) through thereservoir 104 and back into the air conditioning system 120 at thevalve 122B (the low pressure side), in a direction illustrated byarrowheads 140. As the refrigerant flows through thereservoir 104 the high-side pressure overcomes the pressure within thereservoir 104 and forces the air conditioning treatment fluid from thereservoir 104 into the air conditioning system. Generally, the process of loading the treatment into the air conditioning system takes less than about 20 seconds. Thereservoir 104 may comprise a clear material permitting the technician to determine when all the treatment has been removed from thereservoir 100. The technician then closes thevalves 130 to isolate theapplicator 100 from the air conditioning system. The hoses 126 are removed, causing thevalves - In one embodiment an agitating element 116 (see
FIG. 2 ) is disposed within thereservoir 104 for agitating the treatment to promote mixing of the treatment and the refrigerant during the removal process. - According to another (optional) embodiment for injecting the treatment into the refrigerant system, the treatment is mixed with a pressurized canister of refrigerant. When connected to the valve 1228, the pressure within the canister forces the refrigerant and the treatment from the canister into the air conditioning system. Such a
canister 200 is illustrated in phantom inFIG. 3 connected to the valve 1228 via ahose 202. Disadvantageously, this injection method introduces some refrigerant into the air conditioning system, along with the treatment, and therefore may not be desired. - Because air in the
refrigerant path 124 is not desired, to avoid injecting air into the refrigerant path, it is preferred to purge all air from thereservoir 104 during or after filling thereservoir 104 with the air conditioning treatment. To accomplish this purging according to one embodiment, theapplicator 100 is oriented in a vertical position during the treatment filling process. The upper andlower fitting caps 114 are removed from the respective upper andlower fittings 112 and treatment is pumped into thereservoir 104 from the bottom through a lower hose 150 (seeFIG. 4 ) connected to thelower fitting 112. The fluid flows vertically upwardly through thereservoir 104 eventually reaching theupper fitting 112. Anupper hose 152 connected to theupper fitting 112 carries air from thereservoir 104 as the air conditioning treatment fluid enters. Preferably theupper hose 152 comprises a transparent material permitting visual detection of the air or the treatment within theupper hose 152. The loading process is terminated when the treatment is detected within theupper hose 152. - The
upper hose 152 is then removed and the upper fitting cap 114 (seeFIG. 2 ) is removably affixed to theupper fitting 112. Thelower hose 150 is removed from thelower fitting 112 and the lowerfitting cap 114 is removably affixed to thelower fitting 112. Note that it is not necessary to invert theapplicator 100 prior to removing thelower hose 150 as the pressure differential between the upper and lower ends of thereservoir 104 retains the treatment within thereservoir 104. Theapplicator 100 is now ready for use as described above; thereservoir 104 is filled with the air conditioning treatment and air has been evacuated from thereservoir 104. - In one embodiment each fitting 112 is formed integral with its
respective end cap 108/110. In another embodiment eachcap 108/110 comprises a polyvinyl chloride cap into which the fitting 112 is adhesively inserted. The end caps 112 are further adhesively affixed to thereservoir 104 according to known techniques, including use of an adhesive. - In another embodiment, an end cap 170 (particularly for use as the
upper end cap 108 when oriented as illustrated inFIG. 4 ) comprises fins orfingers 180 extending inwardly into the reservoir 104 (from an inside surface of anupper region 170A). Theend cap 170 further comprises wall surfaces 107B (extending along an exterior surface of the reservoir 104). SeeFIG. 5 illustrating a view into an interior of theend cap 170 andFIG. 6 illustrating a side view of theend cap 170. In the latter view it is assumed that theend cap 170 comprises a transparent material and thus thefingers 180 are visible. - After completing the process of filling the
reservoir 104 with the treatment, as described above, theend cap 170 may be affixed to thereservoir 104 in lieu of theend cap 108. Thefingers 180 extending into the interior region of thereservoir 104 ensure that substantially all the air is evacuated therefrom by forcing and remaining air through theupper fitting 112. - While the present invention has been described with reference to preferred embodiments, it will be understood by those skilled in the art that various changes may be made and equivalent elements may be substituted for the elements thereof without departing from the scope of the invention. The scope of the present invention further includes any combination of elements from the various embodiments set forth herein. In addition, modifications may be made to adapt a particular situation to the teachings of the present invention without departing from its essential scope. Therefore, it is intended that the invention not be limited to the particular embodiments disclosed, but that the invention will include alt embodiments falling within the scope of the appended claims.
