(Pump option requires extended cabinet). The Series (HRC) console unit provides a high efficiency WSHP “ductless” solution for spaces where individual, quiet control of the heating and cooling system is important. HRC units are especially ideal where ceiling height and space are limited, or when preserving the integrity of an existing structure. The HRC Series exceeds ASHRAE 90.1 efficiencies, yet maintains small cabinet dimensions. Using HFC-410A refrigerant, the console not only protects the environment, it does so while delivering unprecedented comfort, efficiency, and reliability. Available in sizes 3/4 ton (2.64 kW) through 1-1/2 tons (5.3 kW) with numerous cabinet, water piping and control choices, the HRC Series offers a wide range of units for most any installation. The HRC has an extended range refrigerant circuit, capable of ground loop (geothermal) applications as well as water loop (boiler-tower) applications. Standard features are many. Microprocessor controls, galvanized steel cabinet, polyester powder coat paint and TXV refrigerant metering device are just some of the features of the flexible HRC series. Compressors are mounted on specially engineered sound-tested EPDM grommets for quiet operation. Options such as coated air coil, DDC controls, internal pump and factory-installed water solenoid valves allow customized design solutions. The HRC Series console water-source heat pumps are designed to meet the challenges of today’s HVAC demands with a low cost/high value “ductless” solution.

Design Guide HRC Series Heat Controller Selection Procedure Step 1 Determine the actual heating and cooling loads at the desired dry bulb and wet bulb conditions. Example Equipment Selection For Cooling Step 2 Obtain the following design parameters: Entering water temperature, water flow rate in GPM, air flow in CFM, water flow pressure drop and design wet and dry bulb temperatures. Air flow CFM should be between 300 and 450 CFM per ton. Unit water pressure drop should be kept as close as possible to each other to make water balancing easier. Go to the appropriate tables and find the proper indicated water flow and water temperature. Assume we have determined that the appropriate cooling load at the desired dry bulb 80 F and wet bulb 65 F conditions is as follows: Step 3 Select a unit based on total and sensible cooling conditions. Select a unit which is closest to, but no larger than, the actual cooling load. Step 2 Design Conditions: Step 1 Load Determination: Total Cooling.10,200 BTUH Sensible Cooling.8,350 BTUH Entering Air Temp.80 F Dry Bulb/65 F Wet Bulb Similarly, we have also obtained the following design parameters: Step 4 Enter tables at the design water flow and water temperature. Read the total and sensible cooling capacities (Note: interpolation is permissible, extrapolation is not). Entering Water Temp.90 F Water Flow (Based upon 12 F rise in temp.).2.3 GPM Air Flow.350 CFM Step 5 Read the heating capacity. If it exceeds the design criteria it is acceptable. It is quite normal for WaterSource Heat Pumps to be selected on cooling capacity only since the heating output is usually greater than the cooling capacity. Step 3, 4 & 5 HP Selection: After making our preliminary selection (HRC12), we enter the tables at design water flow and water temperature and read Total Cooling, Sens. Cooling and Heat of Rej. capacities: Step 6 Determine the correction factors associated with the variable factors of dry bulb and wet bulb. Total Cooling.10,800 BTUH Sensible Cooling.9,200 BTUH Corrected Total Cooling tabulated total cooling x wet bulb correction. Heat of Rejection.13,900 BTUH Step 6 & 7 Entering Air and Airflow Corrections: Corrected Sensible Cooling tabulated sensible cooling x wet/dry bulb correction. Next, we determine our correction factors. Step 7 Compare the corrected capacities to the load requirements. Normally if the capacities are within 10% of the loads, the equipment is acceptable. It is better to undersize than oversize, as undersizing improves humidity control, reduces sound levels and extends the life of the equipment. Table Ent Air Air Flow Corrected Corrected Total Cooling 10,800 x 0.976 x 0.954 10,056 Corrected Sens Cooling 9,200 x 1.071 x 0.927 9,134 Corrected Heat of Reject 13,900 x 0.979 x 0.958 13,037 Step 8 Water Temperature Rise Calculation & Assessment: Step 8 When completed, calculate water temperature rise and assess the selection. If the units selected are not within 10% of the load calculations, then review what effect changing the GPM, water temperature and/or air flow and air temperature would have on the corrected capacities. If the desired capacity cannot be achieved, select the next larger or smaller unit and repeat the procedure. Remember, when in doubt, undersize slightly for best performance. Actual Temperature Rise.11.3 F When we compare the Corrected Total Cooling and Corrected Sensible Cooling figures with our load requirements stated in Step 1, we discover that our selection is within /- 10% of our sensible load requirement. Furthermore, we see that our Corrected Total Cooling figure is slightly undersized as recommended, when compared to the actual indicated load. 6

The empirical study suggests that the modern management approach not so much substitutes but complements the more traditional approach. It comprises an addition to traditional management, with internal motivation and intrinsic rewards have a strong, positive effect on performance, and short term focus exhibiting a negative effect on performance. These findings contribute to the current .
