Product Catalog Water Source Heat Pump Axiom™ High Efficiency Vertical Stack — GET ¾–3Tons—60 Hz November 2013 WSHP-PRC020D-EN
Introduction Water-Source Vertical High-Rise The 3/4-ton through 3-ton vertical high-rise water-source heat pump is a floor mounted, “furredin” unit, designed to be hidden from view behind drywall to blend with the room’s natural decor. In multi-story buildings, the units may be stacked one on top of the other to minimize piping and electrical costs. Supply, return and condensate riser piping may be factory mounted to simplify job site installation of the equipment.

Features and Benefits Unit Description The vertical high-rise water-source heat pump is a floor mounted configuration available in a ¾ ton, 1 ton, 1¼ ton, 1½ ton, 2 ton and 3 ton sizes. The unit cabinet may be ordered for early shipment to aid in early installation of drywall, plumbing and electrical. See “Model Number Descriptions,” p. 14.The cabinet design is available in either an 88-inch height (free discharge) or 80-inch height (ducted) configuration.
Features and Benefits Thermostat selections are provided in the “Thermostats and Zone Sensors,” p. 55 section of the catalog.They are available in manual or automatic changeover options. The deluxe controller includes relays for: anti-short cycle compressor protection, random start delay, brown-out protection low pressure time delay, compressor delay on start and night setback control.These extended control features offer greater system performance to extend the equipment’s life. Figure 2.
Features and Benefits is no cross leakage between the water tube and the refrigerant gas (steel tube) coil.The ½” (009/ 012/015/018) and ¾”(024/036) threaded water connections to the water-coil are available on the exterior chassis top. A flexible hose connection with shut-off is typically used between the riser and water-coil in/out connections on the chassis to reduce water vibration. The refrigerant flow metering is made through a thermal expansion valve (TXV).
Application Considerations Advantages of Geothermal The advantages of a geothermal heat pump system can literally decrease heating and cooling operating costs by 30%-40%.The units are durable, and typically last longer than conventional systems.They are protected from harsh outdoor weather conditions, because the unit is installed indoors and the loop underground. According to ASHRAE, the estimated service life for a commercial water-to-air heat pump is 19 years.
Application Considerations Figure 4. Installation illustration Equipment Installation The vertical high-rise unit is versatile in design to fit numerous applications. It is typically applied to dorm rooms, hotels and motels where multiple supply air configurations may be required for individual tenant heating and cooling.The equipment requires little space, and is tucked away from sight, and rough handling.The vertical stack design is economical to install, requiring no ductwork for air supply.
Application Considerations Equipment Risers The riser provides an easy way to facilitate the water flow through a multi-story building and the high-rise heat pump.The high-rise heat pump is best applied to a building with identical zones on each floor, and zones that are typically small. An example building might include a hotel, dorm, condominium or assisted living facility. With these types of buildings, the riser column (external to the unit cabinet) can be stacked one on top of the other.
Application Considerations Table 1. Riser characteristics (continued) Type M (standard) Riser Size (in.) I.D. (in.) O.D. (in.) Copper Wall Thickness (in.) 1½ 1.527 1.625 0.049 2 2.009 2.125 0.058 2½ 2.495 2.625 0.065 3 2.981 3.125 0.072 Note: Pressure ratings for risers are typically greater than the maximum pressure rating of the coaxial water-to-refrigerant heat exchangers.This is true with exception ofType M copper in a 3" diameter.
Application Considerations Riser Size Example Assume a six story building is served by a high-rise water-source heat pump. When referencing the catalog, determine each highrise heat pump uses 3 gallons per minute to meet the required capacity of the 1-ton unit. What is the minimum riser diameter that can be used on each floor? With this arrangement, determine the volume of water used at each floor is 3 GPM.The top floor riser therefore only needs to be sized for 3 GPM. Referring to Table 2, p.
Application Considerations Heat Rejection through a Closed Circuit Cooling Tower Cooling towers serve to reject heat from the condenser water loop to the atmosphere.Two types of cooling towers are used with water-source heat pump systems: open or closed-circuit.The towers themselves are different, but when an open tower is used in conjunction with a water-towater heat exchanger, the control of the two tower types is essentially the same.
Selection Procedures Model Number Two model number designators have been defined for the cabinet configuration, and the chassis configuration. Both model numbers require input for the order to be complete and built to specification. Typically the vertical stack equipment ships in two sections.

Controls Deluxe 24V Electronic Controls The 24V deluxe design is a microprocessor-based control board conveniently located in the control box.The board is unique toTrane water-source products and is designed to control the unit as well as provide outputs for unit status and fault detection. The board is factory wired to a terminal strip to provide all necessary terminals for field connections.
Controls In a high pressure situation, the compressor contactor is de-energized, which suspends compressor operation.The control will go into soft lockout mode initializing a three minute time delay and a random start of 3 to 10 second time delays. Once these delays have expired, the unit will be allowed to run. If a high pressure situation occurs within one hour of the first situation, the control will be placed into a manual lockout mode, halting compressor operation, and initiating the general alarm.
Controls and filter status, reversing valve coil, two-speed fan motor and water isolation valve support (for variable speed pumping). Note: Optional: condensate overflow Tracer ZN510 functions include: Building Control Advantages TheTracer ZN510 controller has the ability to share information with one or several units on the same communication link.This sharing of information is made possible via a twisted pair of wire and a building automation system or throughTrane's Rover™ service tool.
Controls High and Low Pressure Safety Controls TheTracer ZN510 controller detects the state of the high pressure or low pressure switches. When a fault is sensed by one of these switches, the corresponding message is sent to the controller to be logged into the fault log. When the circuit returns to normal, the high pressure control and low pressure control automatically reset. If a second fault is detected within a thirty-minute time span, the unit must be manually reset.

Accessories System balancing hose kit For automatic system balancing of a water source heat pump, the Mesurflo® self-balancing hose kit provides a constant flow rate over the pressure differential rage of 2 to 80 psid. As system pressure changes (through further addition of heat pumps, for example) each individual flow control valve will automatically adjust to the new system conditions.
Mechanical Specifications General Equipment is factory assembled, piped, internally wired, fully charged with R-410A refrigerant and oil. Units are tested at the factory. Products are certified in accordance with AHRIWater to Air and Brine to Air Heat Pump Certification Program which is based ISO Standard 13256-1: 1998. All units have an ETL label that meets USA (UL std) and Canadian (CSA std). Casing The cabinet assembly is constructed of heavy-gauge galvanized steel.
Mechanical Specifications Drain Pan The condensate pan is constructed of corrosive resistant material.The bottom of the drain pan is sloped in two planes to pitch the condensate towards the drain connection. Condensate is piped to a lower base pan through condensate hose for ease of chassis removal. A clear drain hose is factory clamped onto the drain connection for field hook-up.
Mechanical Specifications Deluxe Controls (option) The deluxe control package provides a 75VA transformer with circuit breaker.The Micro-processor based controller is designed to include a lockout relay, anti-short cycle compressor protection, random start delay, brown-out protection, low pressure time delay, compressor delay on start and an open relay for night setback or pump request. Optional wiring from the factory for condensate overflow and compressor enable are also supplied.
