The Hvac/R Professional's Field Guide to Alternative Refrigerants

The HVAC/R Professional's Field Guide to Alternative Refrigerants This 1,000 page plus unique field guide discusses both the procedures and problems contractors and service technicians face when retrofitting a system with an alternative refrigerant. Renowned author Richard Jazwin sorts through the confusion and misinformation regarding the alternative refrigerants and provides the facts every service technicians must know to successfully perform service.
Alternative Refrigerants is divided into two parts. Part One details the new alternative from creation to retrofit, and provides needed information on blends / mixtures, oils, retrofit, safety, and much more. Part Two contains information on alternative refrigerants from the manufactures Copeland Corporation, Dupont Fluoroporducts, ICI Klea, Elf Autochem NA, and Honeywell (Allied Signal Gentron).

Plantain Harvest

Plantain Harvest

Plantain is edible and medicinal, the young leaves are edible raw in salad or cooked as a pot herb, they are very rich in vitamin B1 and riboflavin. The herb has a long history of use as an alternative medicine dating back to ancient times. Being used as a panacea (medicinal for everything) in some cultures, one American Indian name for the plant translates to "life medicine." And recent research indicates that this name may not be far from true! The chemical analysis of Plantgo Major reveals the remarkable glycoside Aucubin. Acubin has been reported in the Journal Of Toxicology as a powerful anti-toxin.

There are many more highly effective constituents in this plant including Ascorbic-acid, Apigenin, Baicalein, Benzoic-acid, Chlorogenic-acid, Citric-acid, Ferulic-acid, Oleanolic-acid, Salicylic-acid, and Ursolic-acid.

The leaves and the seed are medicinal used as an antibacterial, antidote, astringent, antiinflammatory, antiseptic, antitussive, cardiac, demulcent, diuretic, expectorant, haemostatic, laxative, ophthalmic, poultice, refrigerant, and vermifuge. Medical evidence exists to confirm uses as an alternative medicine for asthma, emphysema, bladder problems, bronchitis, fever, hypertension, rheumatism and blood sugar control. A decoction of the roots is used in the treatment of a wide range of complaints including diarrhoea, dysentery, gastritis, peptic ulcers, irritable bowel syndrome, haemorrhage, haemorrhoids, cystitis, bronchitis, catarrh, sinusitis, coughs, asthma and hay fever. It also causes a natural aversion to tobacco and is currently being used in stop smoking preparations. Extracts of the plant have antibacterial activity, it is a safe and effective treatment for bleeding, it quickly stops blood flow and encourages the repair of damaged tissue. The heated leaves are used as a wet dressing for wounds, skin inflammations, malignant ulcers, cuts, stings and swellings and said to promote healing without scars. Poultice of hot leaves is bound onto cuts and wounds to draw out thorns, splinters and inflammation. The root is said to be used as an anti-venom for rattlesnakes bites. Plantain seeds contain up to 30% mucilage which swells in the gut, acting as a bulk laxative and soothing irritated membranes. The seeds are used in the treatment of parasitic worms. A distilled water made from the plant makes an excellent eye lotion.

Plantain Recipes

"Medicinal" herb tea: For colds and flu use 1 tbls. dry or fresh whole Plantain (seed, root, and leaves) to 1 cup boiling water, steep 10 min. strain, sweeten. Drink through the day.

Healing salve: In large non-metallic pan place 1lb. of entire Plantain plant chopped, and 1 cup lard, cover, cook down on low heat till all is mushy and green. Strain while hot, cool and use for burns, insect bites, rashes, and all sores. Note: used as night cream for wrinkles.

I harvested the common plantain pictured here, to make an infused oil, which is slated to become a salve for itches and other skin issues, and a tincture to try during allergy season.

Sumac on a Rainy Fall Day

Sumac on a Rainy Fall Day

Sumac (Rhus glabra)
Other Names: Dwarf Sumac, Mountain Sumac, Scarlet Sumac, Smooth Sumac, Upland Sumac, White Shoemake, Vinegar-tree, Red sumac

Sumac was used extensively by Native Americans for food and medicine. Young shoots and roots are peeled and eaten raw. The fruit is also eaten raw, cooked or made into a lemonade-like drink. The active constituents in Sumac are being studied for use in many diseases some possible applications are in the treatment of TB, diabetes, and some cancers. The plant contains Calcium malate, Dihydrofisetin, Fisetin, Iodine, Gallic-acid-methylester, tannic and gallic acids, Selenium, Tartaric-acid, and many beneficial minerals. An infusion of the bark or roots is alterative, antiseptic, astringent, diuretic, galactogogue, haemostatic, rubefacient and tonic. It is used in alternative medicine for the treatment of colds, diarrhea, fevers, general debility, to increase the flow of breast milk, sore mouths and throats, rectal bleeding, inflammation of the bladder and painful urination, retention of urine and dysentery and is applied externally to treat excessive vaginal discharge, burns and skin eruptions.

The powdered bark is made into a good antiseptic salve. An infusion of the leaves is used for asthma, diarrhea and stomatosis. A poultice of the leaves used to treat skin rashes. The leaves also chewed for sore gums and rubbed on sore lips. An infusion of the berries is diuretic, emetic, emmenagogue, purgative and refrigerant. It is used in the treatment of late-onset diabetes, constipated bowel complaints, febrile diseases, dysmenorrhoea (painful or difficult menstruation). The berries have been chewed as a remedy for bed-wetting. An infusion of the blossoms used as an eye wash for sore eyes. The milky latex from the plant is used as a salve on sores. When broken or cut the plant produces a milky substance which forms a solid gum-like body or gall, containing large quantities of tannic and gallic acid. These galls are used in tanning leather. A medicinal wine can also be prepared from them. An oil extracted from the seeds is used in making candles. Brown, red, and black dye are obtained from the berries, said to be excellent for wool.

Believed by some Native American tribes to foretell the weather and the changing of the seasons, for this reason it was held as a sacred plant.

Cooling Drink: To a handful of berries add 2 cups cold water, let site overnight in cool place, do not heat or liquid will become bitter and astringent. Strain and sweeten to taste.

Alternative Refrigerant Blends & Oils

Ozone depletion, direct and indirect effects of global warming, radiation, and the Federal Clean Air Act have created the necessity for the development of new refrigerants and oils.
Covered in this module are alternative refrigerants to CFCs and HCFCs, the Montreal Protocol, legislation and regulation, regulatory requirements, equipment certification, refrigerant leaks, mandatory technician certification, refrigerant sales restriction, reclaimer certification, safe disposal requirements, record keeping, hazardous waste disposal, and planning for the future. Important definitions that must be known in order to comply with EPAs rules and regulations are also in this chapter.
Also included in this module are;
Refrigerant chemistry for CFC, HCFC, and HFC
Refrigerants and refrigerant blends
Temperature glide
Alternative refrigerants
Oils and their properties
Oil flushing procedures
Oil additives
Oil guidelines
Pressure control settings
This module provides field technicians with a solid understanding of alternative refrigerants, refrigerant blends, oils, and their proper application.
