CFM = 1420 Area = 5.1 ft2 Rated Velocity = 500 fpm Initial Resistance = 0.43 in.w.c. Measured ESP without filter = CFM 5.1 ft2 = 278 fpm fpm 500 fpm = x 0.43 in.w.c. = 0.24 in.w.c. = Filter Pressure Drop 4. Total ESP is = 0.6 in.w.c. which is less than the 1.1 in.w.c. Max ESP To calculate filter pressure drop: Applying Filter Pressure Drop to Determine Total ESP To determine the Total ESP of a unit with the filter in place, follow the steps below: 1. Select the filter type and determine Rated Velocity and Initial Resistance 2. For the model being considered determine Max ESP, CFM and Return Area 3. Determine Filter pressure drop (ΔPs) using the equation above 4. Measure (or calculate) the ESP without filter in place 5. Calculate Total ESP = Measured ESP + Filter Pressure Drop 6. Total ESP should be less than or equal to Max ESP Example: For an YT060 at an air flow of 1960 CFM calculate the filter pressure drop with a 2 MERV 11 filter and determine Total ESP and compare to Max ESP. CFM = 1960 Area = 5.8 ft2 Rated Velocity = 500 fpm Initial Resistance = 0.24 in.w.c.

32 Water Flow Selection: Proper flow rate is crucial for reliable operation of geothermal heat pumps. The performance data shows three flow rates for each entering water temperature (EWT column). The general rule of thumb when selecting flow rates is the following: Top flow rate: Open loop systems (1.5 to 2.0 gpm per ton) Middle flow rate: Minimum closed loop system flow rate (2.25 to 2.50 gpm/ton) Bottom flow rate: Nominal (optimum) closed loop system flow rate (3.0 gpm/ton) Although the industry standard is adequate in most areas of North America, it is important to consider the application type before applying this rule of thumb. Antifreeze is generally required for all closed loop (geothermal) applications. Extreme Southern U.S. locations are the only exception. Open loop (well water) systems cannot use antifreeze, and must have enough flow rate in order to avoid freezing conditions at the Leaving Source Water Temperature (LWT) connection. Calculations must be made for all systems without antifreeze to determine if the top flow rate is adequate to prevent LWT at or near freezing conditions. The following steps should be taken in making this calculation: Determine minimum EWT based upon your geographical area. Go to the performance data table for the heat pump model selected and look up the Heat of Extraction (HE) at the rule of thumb water flow rate (GPM) and at the design Entering Air Temperature (EAT). Calculate the temperature difference (TD) based upon the HE and GPM of the model. TD = HE / (GPM x 485). Calculate the LWT. LWT = EWT - TD. If the LWT is below F, there is potential for freezing conditions if the flow rate or water temperature is less than ideal conditions, and the flow rate must be increased. Example 1: EWT = 50 of Model YT036, full load. Flow rate = 4.5 GPM. Air Flow = 1380 CFM. HE = 29,400 Btuh. TD = 29,400 / (4.5 x 485) = 13.5 of LWT = = 36.5 of Water flow rate is acceptable. Performance Data Tables and Notes: 1. Capacity data is based on 15% (by mass) methanol antifreeze solution (multiplier: 485). 2. Heating data is based on 70 F EAT. Cooling data is based on 80/67 F EAT. Any condition outside performance table(s) requires correction factor(s). 3. Performance data accurate within ±15%. 4. Unit performance test is run without hot water generation. 5. Desuperheater capacity is based upon 2.0 GPM water flow at 70 of entering water temperature. 6. Capacity data includes fan power but not pump power and it does not reflect fan or pump power correction for AHRI/ISO conditions. 7. Performance data is based upon the lower voltage of dual voltage rated units. 8. Interpolation of unit performance data is permissible; extrapolation is not. 9. Performance data is a result of lab testing and is not related to warranty. 10. Due to variations in installation, actual unit performance may vary from the tabulated data. 11. See Flow Rate Selection above for proper application. 12. Continuous research and development may result in a change to the current product design and specifications without notice. Example 2: EWT = 40 of Model YT036, full load. Flow rate = 4.5 GPM. Air Flow = 1380 CFM. HE = 25,300 Btuh. TD = 25,300 / (4.5 x 485) = 11.6 of LWT = = 28.4 of Water flow rate must be increased to avoid freezing. 32
