  • Discharge Superheat - HVAC-Talk
    Sometimes referred to as compressor superheat, total superheat consists of evaporator superheat plus suction line superheat A technician can measure total superheat by placing a thermistor or thermocouple at the compressor's inlet and taking the temperature
  • Setting superheat on TXVs - HVAC-Talk
    So when im adusting the TXV (Sporlan adjustable valve body) turning the valve stem CCW (if looking at the bottom of the valve body or facing the valve stem directly) will open it more to feed more liquid thus decreasing superheat correct? I understand the concept of superheat but just want to be sure which way to turn it
  • R-407c. pages - HVAC-Talk
    Checking superheat or sub-cooling or figuring coil temperature on R-407c is different and can be confusing with the many chart styles and big a temperature glide Look at the three charts below at 40*f The 1st chart shows shows two corresponding pressures at 40*f Vapor pressure and liquid pressure
  • Discharge Superheat - HVAC-Talk
    discharge superheat is one of my favorite topics and checks it is the sum accumulation of the entire refrigeration system but, at the end of the day, it isn't a directly adjustable measurement no valve no knob nothing to adjust
  • What is normal R22 superheat? - HVAC-Talk
    The correct answer is that there is no "normal" superheat Even if the system is TXV metered, the superheat could be vastly different from one system to the next If it is a txv metered system, you only want to check superheat to tell if the txv is operating properly, never to charge
  • TXV and 0 degrees superheat? - HVAC-Talk
    The superheat will also be affected by: what stage the unit is in (high, or low) and if its running in dehumidification mode ( a very low airflow, around 275 cfm per ton) Also, the Infinity system has various system airflow settings- efficiency, high, max, that can affect superheat
  • best way to check superheat - HVAC-Talk
    Evaporator Superheat Check Your Superheat After the box temperature has reached or is close to reaching the desired temperature, the evaporator superheat should be checked and adjustments made if necessary Generally, systems with a design TD of 10¢ªF should have a superheat value of 6¢ª to 10¢ªF for maximum efficiency For systems
  • Discharg Super heat - HVAC-Talk
    Discharge superheat is the temperature of the superheated gas leaving the compressor just clamp your thermometer in the discharge line, 6" away from the compressor The operating discharge temp should be 160F to 212F, a reading over 212F is an indicator of trouble, an old rule of thumb to figure the DS temp is: out side air temp plus 100 F= discharge super heat depending on the type of
  • Superheat - HVAC-Talk
    By definition, the most accurate method of superheat measurement is to obtain an accurate reading of the temperature and pressure of the refrigerant and calculate it using a PT chart The two-temperature method doesn't take into account either the pressure drop through the evaporator or (if it's a refrigerant blend) the glide factor
  • Superheat and subcooling questions - HVAC-Talk
    Required superheat varies depending on the outdoor temp and indoor wetbulb temp If the system has a txv, charge by subcooling (check superheat) in accordance with the manufacturer's instructions I know about finding target superheat just 17 degrees seems high It depends on the operating conditions
