– a refrigeration tool with two jaws for holding works. Most of the time we need a vise to hold the copper tube so that we can braze the joints correctly. Or we must clamp the machine bolt so that we can remove the hex nut. Or simply clamp a piece of steel bar so that we can cut it into the size we need.

It is a refrigeration tool that is use in soldering the joints of two copper tubes together 800 degrees Fahrenheit is required to solder copper tubing. Map gas is generally used in these application, although oxygen-acetylene is also popular except they are bulky and heavy. It can reach a temperature of 3600 degrees Fahrenheit. When brazing copper tube joints, do it in a well ventilated area. Prolong inhalation can cause cancer.

. Any device used to detect leaks in a pressurized system.

- detects leaks by the color of the flame

- listen to the sound of leaks

The tubing that carries the refrigerant to various components is considered to be a vital part of the refrigeration system. Copper tubing is the most common materials in the refrigeration piping circuit.

It is used to connect the major parts of the refrigeration system such as evaporator coil, the compressor, the condenser coil and the expansion valve, most copper tubing is available from 1/8 inch to ¾ inch of a diameter.

The end are capped or plugged to keep the inside of the tubing clean and dry. It is also available in soft and hard types.

This is used in domestic and some commercial refrigeration and air conditioning work, because it is easy to bend and flare. Being bendable, this tubing must be supported by suitable brackets or clamp in installation, so soft copper tubing is often used with flared and soft soldering fittings.

This is used in commercial refrigeration and air conditioning applications. Being hard and stiff, it needs few clamps to support it in installation. Hard drawn copper tubing should not be bent so use straight lengths and fitting to form the necessary tube connection. Hard- drawn refrigeration tubing joints should be silver brazed to eliminate leaks.

This is a thin wall tubing used in refrigeration and air conditioning work, Its

size is practically the same as that of copper tubing, hence connections may be made on

steel tubing by using either flare joints or silver brazed joints.

This is a strong type of tubing that is very resistant to corrosion. It is also easily connected to fitting by either flaring or brazing because of this qualities, stainless steel is often required in food processing, ice cream manufacture, milk handling system, and similar works.

. It is usually used for evaporating units in air conditioning for home and auto-mobile. Commonly, it is used for evaporator (freezer) of the domestic refrigerators. Special type of treatment for soldering or brazing is needed.

This is commonly used tubing in suction lines in many refrigeration system and in commercial air conditioning application. This type serves to prevent vibration in the mechanism. Air conditioning equipment for a motor vehicle

requires the use of flexible tubing since the vehicle is always moving. Flexible tubing hose is made from a variety of special materials. Such materials do not age and remain flexible. These naterials do not allow fluid to leak through the hose wall. They are easy to attach to fittings.

This type of tubing with polyethylene is one of the most common substances used in the manufacture of plastic tubing. The usual safe temperature is from 100 degrees centigrade (oC) to +175 degrees centigrade (oC) you should never use this tubing where fluid temperature goes beyond this limit. Polyethylene tubing is not used in refrigerating mechanism but in cold water lines in water cooled condensers.

In general, polyethylene tubing is not used in the refrigeratlng cycle mechanisms.It is used for cold waterlines, water-cooled condensers,and the like. Polyvinyl chloride (PVC) pipe is used mainly in high pressure applications at low temperaiures for water and gas.

Fitting:

A fitting is a device used to connect tubes of different widths and lengths.

This is used in flared type connection to attach fittings in copper tubing.

There are many different fittings which are hexagonal in shape for wrench attachment.

These threaded fittings must be carefully handled to prevent damage. All fittings used are

based on the tubing size.

- This includes assorted nylon fittings suitable to refrigerant hoses.

This type is used in most tubing and fitting connections

that are either by soldering or silver brazing. Soldered joints are used for water pipes and

drains. Silver brazed joints are used for refrigerant pipes and fittings.

A threaded connector used in a flare assembly for tubing

- a type of refrigerant filter that includes a desiccant material that has an attraction for moisture. The filter drier will remove particles and moisture from refrigerant and oil.

The filter drier is a device that removes foreign matter from the refrigerant. This foreign matter can be dirt, flux from soldering, solder beads, filings, moisture, parts, and acid caused by moisture. Filter driers can remove construction dirt , moisture, and acid. Some sources of moisture in refrigeration systems include poor service practices, air trapped from improper evacuation techniques, leaky systems, and improper handling of polyolester lubricants. The device has a fine screen at the outlet to catch any small particles that may be moving in the system.

A small electromagnetic device to control a switch, motor, or valve .

Potential Relay- are used with single-phase capacitor-start, capacitor-run motors that need relatively high starting torque. Their main function is to assist in starting the motor. These relays are sometimes referred to as voltage relays or potential magnetic relays (PMRs

are used on single-phase, fractional horsepower motors requiring low starting torque. Their main function is to assist in starting the motor. Current relays, also referred to as current magnetic relays, or CMRs, are often seen when capillary tubes or fixed orifices are used as metering devices, because systems employing capillary tubes or fixed-orifice metering devices equalize pressure during their off cycles.

-A system or device that will shut down a system if an overcurrent condition exists.

A device that controls the thermostat which controls the temperature change and changes some dimension or condition within to control an operating device.
