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.

Credit 4 Ozone Depletion 1 Point for passing the Atmospheric Impact calculation “ Select refrigerants and equipment that minimize or eliminate the emission of compounds that contribute to ozone depletion and global warming”. “ The base building HVAC&R equipment shall comply with the following formula, which sets a maximum threshold for the combined contributions to ODP and GWP.” Result: R-22 and R123 equipment may be acceptable. R-410A equipment always meets the requirements
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. 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

Allows an extra “comfort” parameter for the occupant.
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. 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. 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. 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. 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. 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. Series Evap – How it works? Cooling: Heating: Stage 1 or 2 calls for cooling: Hot gas reheat modulates to hold discharge air temperature.
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. Heating Mode We need to preheat the air to about 40 - 45°F in order to energize the compressor for the heating mode.
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. 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.
