The heat pipe calculator provides heat pipe carrying capacity (Qmax), thermal conductivity, and thermal resistance based on heat pipe length, diameter, orientation & condenser / evaporator sizes. Additionally, users can select between standard or performance sintered wick materials. Calculations are based on established theoretical thermal equations tempered with correction factors learned from decades of real-world heat pipe testing. All calculations are based on copper / water heat pipes using a copper sintered wick.

As with any model, we strive to be as accurate as possible. Yet, it’s just a model. CLICK here for a guide on how to use this calculator.

MANY TIMES WE GET THE QUESTIONS, 'HOW DO YOU SIZE THE CONDENSER WITH YOUR EVAPORATOR?'.

HERE ARE SOME HELPFUL GUIDELINES WHEN SIZING.

• SELECT CONDENSING UNIT WITH A LOWER CAPACITY THAN THE EVAPORATOR ( 90% to 100% OF EVAPORATOR )
• DESIGN POINT - 38° SST (USE 40°F FOR SIZING PURPOSES) IF RUNNING ROOM AT 55°
• GOLDILOCKS TYPE OF CONDITIONS
  • USE A GOOD AVERAGE TEMPERATURE NOT WORST CASE SCENARIO
  • ON HOT DAYS JUST LET THE SYSTEM RUN A LITTLE LONGER FOR THE OUT OF BOUNDS CONDITIONS
    • ROOMS ARE SIZED FOR 16 HOUR RUN DAY
  • LOAD ON EVAPORATOR IS CONSTANT- ITS THE CONDENSING UNIT THAT NEEDS TO RUN A LITTLE LONGER
  • SIZE TO A REASONABLE AMBIENT TEMPERATURE
    • IS IT INSIDE?
    • IS IT OUTSIDE?
    • EXAMPLES
      • SAN DIEGO- SIZE FOR 80° NOT 110°
      • PALM SPRINGS- SIZE FOR 100° OR SO AND LET IT RUN LONGER ON THE HOTTEST TIMES OF THE YEAR
  • PUT A FAN CYCLING SWITCH ON THE CU TO KEEP THE HEAD PRESSURE UP TO 80° OR BETTER AMBIENT CONDITIONS TO PROTECT DURING LOW AMBIENT TIMES.
  • CONDENSING UNIT SHOULD HAVE A SUCTION ACCUMULATOR

SO TO SUM IT ALL UP: SIZE AT A SLIGHTLY LOWER LOAD THAN WHAT THE ROOM IS, AT A PLUS 40° SST, AT A REASONABLE AMBIENT TEMPERATURE.

Condenser Capacity Calculation

This HVAC Load Calculator quickly estimates the size of your heating and cooling system in BTU's. The heat load estimate is based on your climate region, total square footage, number of rooms or zones you want, ceiling height, insulation type, number of windows and doors. Calculation; we can ignore this in our calculations since we consider the overall air-side resistance to be constant for all of our calculations). The resistance of the heat exchanger tube is a function of the thickness of the tube s, the conductivity of the tube k, and the mean cross 2. Calculation; we can ignore this in our calculations since we consider the overall air-side resistance to be constant for all of our calculations). The resistance of the heat exchanger tube is a.
