These oil traps help to get any accumulated oil to move upwards, as shown in Figure 2.1. The design of the traps will forcibly cause the gaseous refriger- ant to pass through the oil thus, carrying it upwards back to the compressor.

  • Page 19: Pipe Insulation

    6.8: Pipe Insulation It is only necessary to insulate the cold suction pipe. Do not insulate the hot liquid pipe. If the expan- siondevice is located in the outdoor unit, the liquid pipe must also be insulated. However, for heat pump units, it is important for both pipes to be insulated. This is because of the coldambient temperatures when the unit is running in heat mode.
  • Page 20 a. Pipe Material However, working with R-410A refrigerant will require a stronger pipe material to withstand the higher working pressure. Burst strength of at least 2400 psig will be required. In view of this, do not use the softer refrigeration tubing and Type M pipes. It is recommended that Type L be used for R-410A. Joining of two pipes can be done easily by brazing with a copper ller rod.
  • Page 21 Another method of running these pipes is by using electrical cable trays. These pre- fabricated trays are mounted onto the wall by using saddle brackets. The copper pipes are then clamped onto the trays. The main advan- tage of using these trays is a very neat, organ- ized, and clean installation.
  • Page 22 In some instances, the pipes are required to go through a brackets core hole oor slab by coring method) to accommodate all the pipes going through. Suitable brackets may then be fabricated to hold the pipes together. Figure 5.16: Pipe run through slab 6.11 Pipe Bends Copper pipes MUST NOT be bent with bare hands.

WARNING DO NOT USE OXYGEN TO PURGE LINES OR PRESSURIZE SYSTEM FOR LEAK TEST. OXYGEN REACTS VIOLENTLY WITH OIL, WHICH CAN CAUSE AN EXPLOSION RESULTING IN SEVERE PERSONAL INJURY OR DEATH.
