Problems solved by technology

In addition, the higher carbon number alkenes described in the Smutny patent can also be objectionable in some applications due to the potential level of toxicity of these compounds that can enhance the insecticide activity noted in the Smutny patent
At the same time, the boiling points of these compounds are too high to make their effective use as refrigerants in some applications

Embodiment 1

[0159] The coefficient of performance (COP) is a generally accepted measure of refrigerant performance used, inter alia, to represent the relative thermodynamic efficiency of a refrigerant in terms of specific heat or cooling period, including evaporation or condensation of the refrigerant. In refrigeration engineering, the term expresses the ratio of effective refrigeration to the energy expended in compressing water vapor by a compressor. The capacity of the refrigerant represents the cooling or heating value that provides and provides some measure of the capacity of the compressor to pump the heat required to pump a set volume flow of refrigerant. In other words, a higher capacity refrigerant will deliver more cooling or heating capacity for a specific compressor setting. One way to estimate the COP of a refrigerant under specific conditions of use is from the thermodynamic properties of the refrigerant using standard refrigeration cycle analysis techniques (see, eg, R.C. D...

Embodiment 2

[0164] The compatibility of various refrigeration lubricants with HFO-1225ye and HFO-1234ze was tested. Lubricants tested were mineral oil (C3), alkylbenzene (Zerol 150), ester oil (Mobil EAL 22 cc and Gel 120), polyglycol (PAG) oil (Goodwrench Refrigeration Oil for 134a systems) and poly(α-olefin) oil (CP-6005-100). For each refrigerant / oil combination, three compositions were tested, namely 5, 20 and 50% by weight of lubricant, with the remainder of each being the compound of the invention to be tested.

[0165] The lubricant composition was placed in a thick-walled glass tube. The tube is emptied, the refrigerant compound according to the invention is added and the tube is closed. The tubes were then placed in an air bath environmental chamber where the temperature varied from -50°C to 70°C. The presence of one or more liquid phases was determined by visual inspection of the tube contents at approximately 10°C intervals. When more than one liquid phase was observed, the...

Embodiment 3

[0168] The compatibility of the refrigerant compounds and compositions of the present invention with PAG lubricating oils, when in contact with metals tested for refrigeration and air conditioning systems at 350°C, exhibited better performance than in many refrigeration and air conditioning systems. The conditions found in air conditioning applications are more severe.

[0169] Aluminum, copper and steel sampling tubes are added to thick-walled glass tubes. Two grams of oil were added to the tube. The tube was then emptied and one gram of cryogen was added. Place the tube in an oven at 350°F for one week for visual inspection. The tube was removed at the end of the exposure period.

[0170] Such procedures were used to accomplish the following oil and compound compositions of the invention:

[0171] a) HFC-1234ze and GM Goodwrench PAG oil

[0172] b) HFC-1243zf and GM Goodwrench oil PAG oil

[0173] c) HFC-1234ze and MOPAR-56PAG oils

[0174] d) HFC-1243zf and MOPAR-56P...

Abstract

Various uses of tetrafluoropropenes, particularly (HFO-1234) in a variety of applications, including refrigeration equipment, are disclosed. These materials are generally useful as refrigerants for heating and cooling, as blowing agents, as aerosol propellants, as solvent composition, and as fire extinguishing and suppressing agents.

Description

field of invention [0001] The present invention relates to compositions, methods and systems which are beneficial in a number of applications, particularly compositions involving heat transfer systems such as refrigeration systems. In a preferred aspect, the present invention provides compositions comprising at least one polyfluorinated olefin refrigerant of the present invention. Background technique [0002] Fluorocarbon-based fluids have found widespread use in many commercial and industrial applications, including as working fluids in air conditioning, heat pump, and refrigeration systems, as aerosol propellants, blowing agents, heat transfer media, and gaseous dielectrics. Because of the questionable environmental concerns associated with the use of some of these fluids, including the relatively high global warming potential, it is increasingly more difficult to use fluids with low or even zero ozone depletion potential, such as hydrofluorocarbons ("HFCs") ideal. It i...
