    DUCT SIZES FOR HOMES Velocity Approximately 800 Feet Per Minute THE INDOOR EVAPORATOR COIL 1. EVAPORATOR COIL is a finned coil through which air in the home is circulated. Heat from the air is transferred to the liquid refrigerant inside the evaporator coil. The coils for use in AH air handlers are in an A-shaped configuration (A Models).

  • Page 19 TUBING INSTALLATION The compressor oil is constantly pumped through the refrigerant lines in normal operation of an air conditioning system. To ensure proper lubrication of the compressor by avoiding oil accumulation at undesirable points in the system, follow the guidelines listed below: 1.
  • Page 20 NOTE: Multiple suction line traps are recommended for longer or multiple suction lines. See Figure J. An inverted trap should be installed on the horizontal suction line near the evaporator coil to prevent liquid flood back to the compressor (See Figure K.) if the indoor evaporator coil is located 10’ or more above the condensing unit.

  • Page 21: How To Measure Liquid Sub-Cooling

    HOW TO MEASURE LIQUID SUB-COOLING (NOTE: A good electronic thermometer and accurate liquid pressure gauge with a check valve in the Schraeder fitting are necessary). : Failure to use a liquid side hose fitting with a built in check valve may result in personal injury and significant refrigerant loss.

  • Page 22: Measuring Temperature Drop Across The "A" Coil

    A liquid sub-cooling of about 10 o F leaving the condenser is good over a wide range of operating conditions for a system with a TXV in the evaporator like the AH2436A/BE1 & AH4260A/BE1. MEASURING TEMPERATURE DROP ACROSS THE “A” COIL: The temperature drop across the coil should be around 18 o F to 23 o F difference between inlet and outlet air.
