HOW TO REPAIR REFRIGERATION

Before sealed system work can be preformed a refrigerant recovery EPA and LOCALLY approved certification is required, additionally, EPA and LOCALLY approved refrigerant recovery equipment is required.

SEALED SYSTEM REPAIR

Sealed system repairs should be properly diagnosed before entering into a repair of the system. It is important to follow proper procedures when doing a system repair for safety reasons and that the repair will result in a restoration of the system to proper factory standards.

SAFETY REMINDERS

1) Do not heat any system component with an open flame for any reason.

2) Do not solder until you are sure that all refrigerant has been removed from the system.

3) Do not heat the charging cylinder with an open flame. Use warm water only and do not exceed 125˚F(not too hot to keep your hand in.)

4) Do not over fill any charging cylinders, as they could explode when over filled.

5) Use proper wrenches.

6) Use safety goggles when working with refrigerants.

7) Keep a fire extinguisher within easy reach.

8) Watch flame direction when soldering so as not to burn clothing, wiring or other components.

9) Solder in a well ventilated area. If a high concentration of freon is present, an open flame will create phosgene gas which can be harmful.

GOOD FIT

PROPER JOINT FIT CLEARANCE

0.01" TO 0.03"

PROPER SOLDERING

Joint clearances should be maintained so that the brazing alloy will flow between the closely mated surfaces rather than forming large fillets. This films make the strongest joints, capillary attraction also work best with close tolerance. The best clearance is between 0.01" to 0.03" , the amount of lap will be approximately 3/8" depending on the swaging tool used. (Figure 1.)

CLEANING TUBING

To make a sound, leak tight joint, the brazing alloy when raised to brazing temperature, must wet and flow freely over the entire surface of the tubing in the joint area. To assure this, the tubing surfaces must be free of all dirt, grease, oil and oxides otherwise the alloy will not wet and flow properly over any surface with these elements present. Cleaning can be done with an abrasive cloth or steel wool. Never blow into the tubing because this will introduce a lot of moisture into the system. Open tubing joints should be covered if exposed for long periods of time.

PROPER FLUXING

Flux is necessary when using silver solder; it is not required when using silfos on copper to copper joints. To do a good job the flux should cover the tube surface completely. Be careful not to introduce any flux inside the tubing. Fluxing should be done after the tubing is mated together and just before brazing is done. Do not allow it to dry out. When brazing, the flux should become entirely liquid and clear, like water. The temperature will be at 1100˚F and only a little more heat will allow the alloy to flow freely into the joint.

Composition of Torch Flame.

HEATING THE TUBING

Direct the torch flame so that the larger tube receives most of the heat. Silver solder flows at 1200˚F and silfos flows at 1300˚F. Heat all around the tubing. The flame is composed of two cones, a smaller inner cone (pale blue) in calor and a much larger outer cone. The hottest part of the flame is at the tip of the inner cone. The flame should be directed at the joint with the tip of the cone just touching the surface of the tubing. Figure 3 and 4.

DEHYDRATING SEALED SYSTEM

Many servicers feel that since air conditioners run with evaporator temperatures above 33˚F, moisture will not present a problem. Nothing is further from the truth. Oxygen in moisture plus the heat produced during compression will react with the refrigerant oil to produce harmful acids in the system which will break down motor winding insulation, create sludge and pit component parts, reducing efficiency of the air conditioner and shortening the life of compressors. There it becomes mandatory that good dehydrating practices be adhered to at all times. Proper hook up procedures as shown in Figure 5 must be used in order to pull and good vacuum from the system. The use of a good vacuum pump is very important so that the boiling point of any water in the system will be lowered to a point where it will vaporize and be expelled from the system in the form of vapour.

Type of evacuation methods

1. Piston Type Compressor No good.

System parts must be above 110˚F.

2. Rotary Vacuum Pump Disavantages. Low CFMC. 4 oil gets dirty.

3. Single State Vacuum Pump will not clean oil. Oil must be changed often.

4. Two Stage Vacuum Pump will reach 50 microns. First stage is below atmospheric pressure.

HIGH VACUUM PUMPHook up for Evacuation and charging

Figure 5

It becomes clear that good equipment and maintained properly must be used in order to remove air and moisture from the system. When a vacuum of 1,000 to 500 microns is reached, block off the vacuum pump from the system. This is done by closing the value between the pump and system. If the micron gauge does not increase above 1,000, the system is free of moisture and no leak exists. If the micron gauge increases to higher levels moisture or a leak exists.

RUNNING CAPACITOR

FAN CAPACITOR

LEAKS

Several methods are used to detect leaks in systems.

Electronic Leak Detectors are very sensitive and are able to detect leaks down to 1/2 ounce per year. A good electronic leak detector is generally far better in locating very small leaks. Halide Torch be sure the room is free from refrigerant vapours. Watch the flame for the slightest change in calor. A very faint green indicates a small leak. The flame will be unmistakably changed to green or purple when large leaks are encountered. To simplify leak detection pressurize the system to approximately 75 lbs. Some leaks can be located by a visual inspection of the system components and solder joints and if oil is found at any given location it generally is a sign that a leak exists at that point due to the fact that flame does carry oil with it travels through the system.

Soap Bubbles

Liquid detergents can sometimes assist in finding small leaks by brushing detergent on the suspect area and watching for bubbles. Before applying detergent be sure that the system is pressurized.

Tap line devices are permissible for diagnosis only they are not suitable when evacuating the system. After the diagnosis has been made they must be removed so that the system will be restored to a hermeticly sealed condition.

COOLING LOAD ESTIMATE FORM

INSTRUCTIONS FOR USING COOLING LOAD ESTIMATE FORM FOR ROOM AIR CONDITIONERS

(AHAM PUB. NO. RAC-1)

A. This cooling load estimate form is suitable for estimating the cooling load for comfort air conditioning installations

which do not require specific conditions of inside temperature and humidity.

B. The form is based on an outside design temperature of 95˚F dry bulb and 75˚F wet bulb. It can be used for areas in

the continental United States having other outside design temperature by applying a correction factor for the particular locality as determined from the map.

C. The form includes "day" factors for calculating cooling loads in rooms where daytime comfort (such as living rooms,

offices, etc.).

D. The numbers of the following paragraphs refer to the correspondingly numbered item on the form:

1. Multiply the square feet of window area for each exposure by the applicable factor. The window area is the area of the wall opening in which the window is installed. For windows shaded by inside shades or venetian blinds, use the factor for "Inside Shades". For windows shades by outside awnings or by both outside awnings and inside shades (or venetian blinds), use the factor for "Outside Awnings". "Single Glass" includes all types of single thickness windows, and "Double Glass" includes sealed air space types, storm windows, and glass block. Only one number should be entered in the right-hand column for item 1, and this number should represent only the exposure with the largest load.

2. Multiply the total square feet of all windows in the room by the applicable factor.

3a. Multiply the total length (linear feet) of all walls exposed to the outside by the applicable factor. Doors should be

considered as being part of the wall. Outside walls facing due north should be calculated separately from outside walls facing other directions. Walls which are permanently shaded by adjacent structures should be considered as being "North Exposure". Do not consider trees and shrubbery as providing permanent shading. An insulated frame wall or a masonry wall 8 inches or less in thickness is considered "Light Construction". An insulated frame wall or a masonry wall over 8 inches in thickness is considered "Heavy Construction".

3b. Multiply the total length (linear feet) of all inside walls between the space to be conditioned and any unconditioned

spaces by the given factor. Do not include inside walls which separate other air conditioned rooms.

4. Multiply the total square feet of roof or ceiling area by the factor given for the type of construction most nearly describing the particular application. (Use one line only.)

5. Multiply the total square feet of floor area by the factor given. Disregard this item if the floor is directly on the ground or over a basement.

6. Multiply the number of people who normally occupy the space to be air conditioned by the factory given. Use a minimum of 2 people.

7. Determine the total number of watts for lights and electrical equipment, except the air conditioner itself, that will be in use when the room air conditioning is operating. Multiply the total wattage by the factor given.

8. Multiply the total width (linear feet) of any doors or arches which are continually open to an unconditioned space by the applicable factor. NOTE: Where the width of the doors or arches is more than 5 feet, the actual load may exceed the calculated

value. In such cases, both adjoining rooms should be considered as a single large room, and the room air conditioner unit or units should be selected according to a calculation made on this new basis.

9. Total the loads estimated for the foregoing 8 items.

10. Multiply the sub total obtained in item 9 by the proper correction factor, selected from the map, for the particular locality. The result is the total estimated design cooling load in BTU per hour.

E. For best results a room air conditioner unit or units having a cooling capacity rating (determined in accordance with

the NEMA Standards Publication for Room Air Conditioners, CN 1-1960) as close as possible to the estimated load should be selected. In general, a greatly oversized unit which would operate intermittently will be much less satisfactory than one which is slightly undersized and which would operate more nearly continuously.

F. Intermittent loads such as kitchen and laundry equipment are not included in this form.
