ABSTRACT Because of the development of Hydro FluoroCarbon (HFC), it is speculated that there will be some difficulties in

lubrication at the sliding parts in compressors, especially at thevanes tip in rotary compressors and that a precise lubrication analysis and an exploit of materials for the sliding parts of compressors will be needed.

In this paper, evaluations of lubricating effects at the vane tip and ratio of metal contact area, an examination of an optimum design of a vane, and an exploitation of materials for a vane were discussed respectively.

First, a friction experiment under dry condition was operated to investigate a lubricating effects from the refrigerants. By this experiment, it was discovered that HFC owned somewhat of lubricating effect from fluoride, although it was smaller than that of Chloro Flu oro Carbon(CFC) and Hydro Chloro Fluoro Carbon (HCFC) from chloride. Therefore, one could say that a lubricating effect would be certainly reduced by using HFC as an alternative refrigerant.

The next experiment conducted was to evaluate the ratio of metal contact area at the vane tip by measuring the electric contact resistance between the vane and the roller, and an optimum design for a vane was attempted to be made. As a result of the experiment, it was discovered that a reduction of the ratio of metal contact area was possible, however, it was awfully difficult to gain complete hydrodynamic lubrication.

Therefore, an exploitation of materials for vanes was progressed by using adhesive energy on the materials, and improvements of scuffing and wear resistances were attempted by using composites of hard particles and ceramic coatings.

INTRODUCTION The usage of Chloro Flu oro Carbon (CFC) and Hydro Chloro Flu oro Carbon (HCFC) for refrigerants are regulated

by law in order to prevent the depletion of Ozone Layer, and exploitations of alternative refrigerants and machinery for those refrigerants are in progress. One of the most important tasks for these exploitations is keeping the reliability of compressors, and Fig. 1 summarizes a problem statement and measures to solve it. This paper discusses lubricating effects at the vane tip using HFC, an evaluation of lubricating condition at the vane tip, and also -methods to improve this condition. The compressor used for these experiments is a rotary compressor that requires very severe lubricating conditions.

LUBRICATION EFFECTS IN HFC REFRIGEAANTS

1. EXPERIMENT

A dry friction test was conducted by using Shell Four Ball Test

Method. Rolling bearings of steel were used as samples for testing. ~

CFC12, HCFC22, HFC32, HFC134a, HFC125, and nitrozen, that were .:::,

set at the room temperature, were used as ambient gases.

After the dry friction test, the surface of the samples was analyzed

by X-ray Photoelectron Spectroscopy (XPS). 1)

2. RESULT and DISSCUSION

The result of the mesurement of seizure load was shown

on Fig. 2 (a). They were categorized in three groups, and they

were CFC HCFC Group that contained Cl in their molecules (CFC12,

HCFC22), HFC Group that did not contain Cl in their molecules

(HFC134a, HFC32, and HFC125), and Inert Gas Group (nitrogen).

CFC HCFC Group that contained Cl had the heaviest seizure load,

and this fact could be representing the effect of Extreme Pressure

(EP).

HFC Group that did not contain Cl had the next heaviest seizure

load, and remarkable difference was observed between the seizure

load in HFC Group and in Inert Gas Group (nitrogen). This result

proved that some sort of EP was affected, and then, elements on the

friction surface were analyzed. Fig. 3 showed the result of it. From

this result, F was appearently detected on the friction surface and it

was speculated that a fluoridized tunic was formed on the friction

surface. This fluoridized tunic could be assumed as fluoride iron by

the chemical shift on XPS peak.

From the result discussed above, one could say that in HFC, the

seizure load was heavier than that in inert gases by the effect of EP

that could be possibly caused by fluoride, and was less than that in

CFC and HCFC that contained Cl. Also, Fig.2 (b) and (c) showed

that the same type of trend as the case of seizure load could be seen

in wear and friction coefficient.

ANEVALUATION OF LUBRICATING CONDITION AT THE VANE TIP

I. EXPERIMENT

The vane was designed for the purpose of measuring the ratio of metal contact area. The schematic of the vane was shown on Fig. 4. Tool steel used as an electrode was inserted into the ceramic vane.

This vane was mounted in a compressor. The circuit shown in Fig. 5 was giving very small amount of voltage between the vane and the rolling piston, and the electric potential on a contact area was measured at the same time of measuring the rotation angle of the crank shaft.

In this experiment, the value of the impressed voltage was a very important factor. This value was determined as 0.2 volt as a result of optimizing the circuit. Also, it was assumed that the electric potential on a contact area was 0.04 volt from the fact that it did not record under this value when the compressor is and is not running. 2)

2. RESULT and DISCUSSION

The trend of electric potential on a contact surface was shown on Fig. 6. This data was recorded by varying the pressure difference between inlet and outlet. From this diagram, it was noticed that as the pressure difference increased, the electric potential on a contact area decreased, which meant that the ratio of metal contact area was increasing. One of the reason for this phenomenon was that the load on top of the vane was increased since the pressure difference increased. The other reason was that the viscosity of the oil decreased since outlet pressure increased and the temperature of outlet gas rose up.

By observing the crank's one rotation, the highest ratio of metal contact area was recorded around the rotation angles of 90 deg. and 270 deg.. This was because the sliding velocity between the vane and the roller was the smallest at these two angles.

Next, Fig. 7 showed the trend of the electric potential on a contact area with the operating frequency varied from 40 Hz to 90 Hz. Ibis diagram indicated that the ratio of metal contact area was decreased because the rotational speed increased as the operating frequency increased.

From all the result above, the ratio of metal contact area between the vane and the roller could be evaluated. Also, the trend of the ratio of metal contact area in respect to the pressure difference and the operating frequency could be observed carefully. The lubricating condition between the vane tip and the roller was mixed lubrication that was to happen in any state of metal contact when running a compressor.

AN IMPROVEMENT OF LUBRICATING CONDITION AT THE VANE TIP

1. OPTIMUM DESIGN OF A VANE

An improvement of lubricating condition was attempted by optimum design of a vane. The mixed lubrication analysis was presented by Tanaka3), and this analysis was verified by our evaluation of the lubricating condition in this paper. Taking Tanak&·~ analysis as a guideline, an experiment was conducted to record the ratio of metal contact area with thickness of a vane and radius of curvature at the vane tip varied. These data points were plotted on Fig. 8. It showed that smaller the thickness of a vane was, smaller the ratio of metal contact area became, and that larger the radius of curvature was, smaller the ratio of metal contact area became. From these trends, it was possible to improve the lubricating condition by reducing thickness and by enlarging radius of curvature, however, it was very difficult to gain complete hydrodynamic lubrication.

Since it was very difficult to gain complete hydrodynamic lubrication by optimum design, exploiting materials for a vane was essential in order to do so. To improve scuffing resistence and wear resistence, currently exploiting materials such as steel with surface

treatment, composite materialswith additive of hard particles, and composite materialswith additive of solid lubricant are in progress. Finding effective parameters was a very significant step of exploiting materials efficiently. It was hYPothesized that adhesion energy and plastic index ratio were two of those important parameters. Figure. 9 (a) showed a

relationship of adhesion energy with seizure load and Fig. 9 (b) showed a relationship of plastic index ratio with the seizure load. Both of adhesion energy and plastic index ratio were correlated with seizure load. It became evident that the seizure load could be maximized by minimizing these parameters.

CONCLUSION

1. Lubrication effects in HFC refrigerants

. HFC refrigerants forms fluoride on the material surface, and that was capable to improve lubricity. However, the

lubrication effect in HFC refrigerants was smaller than that in CFC and HCFC refrigerants.

2. An evaluation of lubrication characteristics at the vane tip

Metal contact conditon between the vane tip and a rolling piston could be evaluated by measuring the electric

contact resistance. A ceramic vane, which a steel electrode was installed on, was used for this measurement. The

lubricating condition at the vane tip was mixed lubrication that was to happen in any state of metal contact when

running a compressor.

3. Improvement of the lubricating condition at the vane tip

The ratio of metal contact area could be reduced by varying the thickness and a radius of the curvature at the vane

tip. Although, it was very difficult to gain complete hydrodynamic lubrication.

In order to improve the lubricating condition by means of exploiting materials for vanes, an effective method

would be reducing adhesion energy and plastic index.

Preface

The 1996 International Compressor Engineering Conference at Purdue (1996 ICECP) is the thirteenth biennial conference of this series, which started in 1972 under the name of Purdue Compressor Technology Conference. The name change reflected the nature of the conference more accurately and occurred in 1986. The conference will be run in parallel with the 1996 International Refrigeration Conference. The two conferences are available to attendees with registration at either one, conferring attendance and proceedings privileges to both. Proceedings of the individual conferences are available as individual publications.

The goals of the compressor conference remain the same as for the previous conferences:

• to present research and design results in positive displacement compressors,

• to review the state-of-the-art of compressor development and application,

• to educate engineers starting in the compressor field, and • to provide an easily accessible reference for compressor engineers.

At the time of writing this preface, there are 133 papers in the 1996 proceedings, bound in two volumes. As always, there is considerable international participation.

The proceedings are organized by session, except that sessions may not be complete. The final program distributed at registration should be consulted. Papers that arrived too late for printing are held back and will be printed in the 1998 proceedings. Appendix A contains papers from the 1994 conference which, for one reason or another, did not make it into the 1994 proceedings.

It is the policy of this conference not to distinguish between invited and contributed papers. In the same spirit, the published page limit of six pages was uniformly enforced to a reasonable degree. This means that papers coming in with seven pages were still accepted.

As in past proceedings, it will be necessary for the reader to scan all papers in all sessions for information in a particular interest area, since most papers could have appeared in more than one session. To help the reader somewhat, a keyword index is again provided. Since in time individuals become known in their area of compressor activity, an author index can also be quite helpful when searching for information and has therefore been assembled.

On behalf of the organizing committee, I like to thank the members of the advisory committee, the cooperating professional societies and their representatives, all authors and session chairmen, and all industrial and academic organizations that have given such generous assistance in many ways. I also like to thank Cynthia Quillen, our conference secretary, and Barbara Meyer, conference coordinator, for their valuable

XV

help. Donna Miller, Sara Crutchfield, and Jean Brant provided important services, singling them out from a number of other people who were essential to putting together these proceedings. Last but not least, Phyllis Hurst, the 1994 conference secretary, and now editorial assistant of the Journal of Sound and Vibration, was a valuable resource.

Also, I would like to acknowledge the efforts of John J. Jacobs, who organized the two sessions on turbo compressors. In the past, we occasionally had papers on turbo compressors, but this year's strong showing is a first for us.

The next conference, the 1998 International Compressor Engineering Conference at Purdue, is planned tentatively for July 14-17, 1998.

Dr. Werner Soedel Professor of Mechanical Engineering and Conference Chairman

Policy for Publishing Conference Papers in Archival Journals

The organizing committee recommends to all authors who have papers that satisfy the criteria for archival journal articles to submit them to such journals for publication. Because of the relatively small number of copies, publication in the proceedings of the International Compressor Engineering Conference at Purdue does not constitute prior publication as far as many journal editors are concerned. If in doubt, an inquiry should be made. In most cases, the limit of six pages will require the creation of an expanded journal article version, which would qualify as a new publication anyway.

The criteria for archival papers are that they should contain original, quantitative, detailed scientific materials that are placed in proper perspective relative to prior work and are supported by references to the appropriate literature. Thus, not all conference papers are suitable. Some describe present practice; or report on procedures that were applied first by someone else; or report design features which, although important to conference participants, have relatively short temporal interest.

The organizing committee requests that authors who choose to submit their papers to archival journals acknowledge that those papers were presented at the 1996 conference and send a copy of each submitted manuscript to the conference chairman.

Purdue University sponsors this conference to provide a forum for the free exchange of ideas on the engineering state-of-the-art in the compressor field. The ideas expressed are those of the author(s) and do not necessarily represent the opinions or policies of the University or the cooperating organizations. The papers are not subject to the formal review procedures of the separate cooperating organizations as they would be if they were to be published by the cooperating societies. Instead, they are subject to the review procedures of the organizing committee.
