The suction pressure is the most significant pressure reading. If a unit is suspected of having a low refrigerant charge, the unit should be recharged using the suction pressure as a guide.

  • Page 44: Evaporator Superheat

    To measure superheat at the evaporator, a suction pressure reading at the outlet of the evaporator would be desirable. Since most residential cooling systems (including Thermo Pride evaporators) do not provide a test port (sometimes referred to as a Schraeder port) at the evaporator, the suction pressure must be read at the suction inlet to the compressor.

  • Page 45: Definition Of Subcooling

    It is preferable to measure pressure of the liquid line at the evaporator, but most manufacturers, including Thermo Pride, do not include test ports (or Schraeder valves) at the evaporator. Typically, it would be necessary to compensate for the pressure drop through the line connecting the condenser and the expansion valve.

  • Page 46: Recommendations For Operation At Low Temperatures

    Refer to Example 4, in Appendix B: Calculations of this manual, for a sample calculation of how to figure the degree of subcooling for the condenser. In general, Thermo Pride recommends the evaporator operate with a subcooling of between 5° and 15°F.
