Serial #
2. Flow Rate in gpm
WATER IN Pressure:
WATER OUT Pressure:
Pressure Drop: a - b
Look up flow rate in table:
3. Temp. Rise/Drop Across Coaxial Heat Exchanger
WATER IN Pressure:
WATER OUT Pressure:
Temperature Difference:
4. Temp. Rise/Drop Across Air Coil
SUPPLY AIR Temperature:
RETURN AIR Temperature:
Temperature Difference:
5. Heat of Rejection (HR)/Heat of Extraction (HE)
Brine Factor
2
:
HR/HE = d x g x k
STEPS 6-9 NEED ONLY BE COMPLETED IF A PROBLEM IS SUSPECTED.
6. Watts
Volts:
Total Amps (Comp. + Blower)
:
3
Watts = m x n x 0.85:
7. Capacity
Cooling Capacity = l - (o x 3.413):
Heating Capacity = l + (o x 3.413):
8. Efficiency
Cooling EER = p / o:
Heating COP = p / (o x 3.413):
9. Superheat (S.H.)/Subcooling (S.C.)
Suction Pressure:
Suction Saturation Temperature:
Suction Line Temperature:
S.H. = t - s
Head Pressure:
High Pressure Saturation Temp:
Liquid Line Temperature
:
4
S.C. = w - x
NOTES:
1
Steps 3-9 should be conducted with the hot water generator disconnected.
Use 500 for pure water, 485 for methanol or Environol™. (This constant is derived by multiplying the weight of one gallon of water (8.34) times the minutes
2
in one hour (60) times the specific heat of the fluid. Water has a specific heat of 1.0.
3
If there is only one source of power for the compressor and blower, amp draw can be measured at the source wiring connection.
Liquid line is between the coax and the expansion device in the cooling mode; between the air coil and the expansion device in the heating mode.
