    20. 20. Why switch to R- 410A now? Montreal protocol and the US Clean Air Act says it can be: We can not make R-22 units after January 1, 2010 R-22 can be used for new equipment until 2010. R-22 can be used for service until 2020. Production caps will make the availability of R-22 uncertain. R-22 compressors will become less available. R-22 replacement parts and refrigerant costs will increase. High repair costs will force units to be replaced. FHP is committed to offering all of our product lines with R-410A.

    37. 37. The Formula
    38. 38. Credit 4 Ozone Depletion The strategy for the consulting engineer is to select equipment with reduced refrigerant charge and increased equipment life. Maintain equipment life to prevent leakage of refrigerant to the atmosphere. HOW? The non-R410A and pro-R123 boys (Trane) must have cried to the Green Bldg Council. It says this, to get the 1 Point, fill out a sheet that calculates the weighted average of the sum of LCGWP and LCODP for all equipment above ½ lb. refrigerant – that applies to all water source hp’s. We have included such a spreadsheet!

    53. 53. The ECM line is a brushless-DC motor with built-in speed and torque controls. The ECM has all the efficiency and speed control advantages of a DC motor plus programming options that can optimize system performance. The ECM uses 1-phase AC input power and converts it into 3-phase operation. 3-phase motors have superior efficiency and reduced noise to single phase motors. The ECM uses GE patented back EMF (electromotive force) sensing to determine rotor position and perform the commutation function. The motor utilizes a permanent magnet rotor resulting in near zero rotor losses. The rotor is connected to the shaft though resilient rings to absorb high frequency torque ripple. ECM Motor Option
    54. 54. Better Control with ES 2-Stage Unit Because the unit does not shut off at reduced loads and continues to run, good dehumidification control – part load High Efficiency at both full and part load Good for imbalanced heat and cool loads Now comes in 3 phase, 460 and 208-230 Commercial market Stage 1 cooling is about 72% of full load Stage 1 has EER improvement of 14% Heating is 74% and 18% more efficient Stage 1 has 33% less CFM due to ECM motor Lower S/T ratio, higher latent cooling

Phase Loss and Phase Reversal <ul><li>3-Phase Monitor Protects Against: </li></ul><ul><li>Phase loss </li></ul><ul><li>Phase reversal </li></ul><ul><li>Phase unbalance </li></ul><ul><li>Reverse rotation on 3-phase scrolls </li></ul>How it works: 3-phase power is connected to the bottom 3 terminals, 208, 230, 460 or 575 volts. If the phases are out of sequence, or if one drops out, a set of normally open contacts, Y/Y-OUT, will never close, dis-arming our 24 volt control circuit. If a phase is lost, reversed, or imbalanced while energized, the contacts will open and remain open until the error is corrected. A “green” LED indicates the output is energized and a “red” LED indicates a fault. It is auto reset.
    69. 69. Extra Quiet Sound Packages Different Packages for Different Units Depends on the compressor type. Compressor Blanket Covers the compressor with ½” thick closed cell foam. Not available on rotary type - sizes 007, 009, 010, 012. Not on scroll type, GT, GS, EV, ES & EM/EC 060, 070. Insulated Compressor Base Pan Covers the base pan with ½” thick closed cell foam. Almost all units.

    77. 77. Why Hot Gas Reheat ? <ul><li>It is a dehumidification cycle to control humidity </li></ul><ul><li>Hot Gas Reheat </li></ul><ul><li>Cools the entering air with the evap coil. </li></ul><ul><li>Reheats the air with the hot gas reheat coil. </li></ul><ul><li>Allows the occupant to set his/her desired humidity and temperature levels . </li></ul><ul><li>Reduces the humidity in the space without having to cool the space down to a low temp. </li></ul>5. We deliver neutral temp air to the space.
    78. 78. Wallstat Control – combo stat/humid Wall Thermostats Programmable – night setback Cooling setpoint – by time of day Heating setpoint – by time of day Humidity setpoint – dehumidification Includes a “dehumidification” terminal to energize full cooling, both compressors, and both reheat valves. Allows an extra “comfort” parameter for the occupant.

    80. 80. Staged Hot Gas Reheat Here’s How it Works: Humidistat calls for reduced humidity – starts compressor and reheat. Reheat drops out if the space temp is not satisfied = “cooling dominant”. 77°F
    81. 81. Staged Hot Gas Reheat Rule of Thumb: The leaving air off the reheat coil is 2°F lower than the EAT to DX coil. Btu/hr reheat = .90 x sensible cooling Btu/hr. It is a slight cooling process. 77°F
    82. 82. Why consider Hot Gas Reheat? It controls humidity. The “reheat” is free. It is heat that is normally rejected to the water loop. Does not require extra input energy. Good for larger spaces. Great for hotel lobbies, locker rooms and conference rooms.
    83. 83. 100% Outdoor Air Series Evap Unit Delivers neutral air: Cool to 55 F and reheat to neutral air, 70-80 F. Designed for 160-200 CFM/ton – single fan Dual compressors 6 row cooling coil Hot gas by-pass Hot gas reheat with modulating control
    84. 84. Modulating Hot Gas Reheat How it works: Cooling comes on and the hot gas reheat valve modulates to maintain discharge air temp. Application is 100% Outdoor Air Neutral air is delivered to the return path of the other heat pump units.
    85. 85. Series Evaporator for 100% OA Now we are introducing 6,000 CFM thru 2 evap coils Take a 30 ton unit at 6,000 CFM = 200 CFM/ton
    86. 86. Series Evap – How it works? Cooling: Heating: Stage 1 or 2 calls for cooling: Hot gas reheat modulates to hold discharge air temperature.
    87. 87. Series Evap – Psychrometrics
    88. 88. Typical (100% OA) Series Evap Unit The unit will have: Dual compressors Hot Gas By-pass – both circuits Modulating hot gas reheat Dual evap coils arranged in series – 6 rows Two compressors operate in cooling One compressor has hot gas reheat One compressor has compressor heating Special fan – convert to a single fan
    89. 89. Heating Mode We need to preheat the air to about 40 - 45°F in order to energize the compressor for the heating mode.
    90. 90. Heat Mode - Preheat Loop Water Coil We can add a 3-4 row preheat water coil, factory-mounted, to run 60°F loop water thru and get about 48°F leaving air temp of the coil.
    91. 91. Reduce Operating Costs Pre-cools the entering air with water from the loop via a 3-4 row coil. First stage is cooling. If the water is cold enough – open the 3-way diverting valve to the econo coil. Then compressor. Water always flows thru coax. Rule of Thumb: Econo coil produces ½ of the cooling at 50°F ent. water. Waterside Economizer – Free Cooling It is being applied to geothermal jobs.
    92. 92. Model WW R410A Water-to-water Units – 2 to 35 tons Makes warm water, 120°F and cold water, 45°F. Our fastest growing product. There are many different applications. No brazed plate heat exchangers – coax only

Allows a different GPM in the water-to-water load side versus the terminal units. Size to obtain a total piping volume of 10 gallons/ton; WW420 needs 300 gallons of water volume.
