Distributed Pumping System

A distributed pumping system contains either a single or dual pump module, specifically sized for each water-source heat pump, then connected directly to the units supply and return lines.

The distributed system’s supply and return lines should be sized to handle the required flow with a minimum pres- sure drop.

1. Hose kits are used to connect the

water supply and return line to the

water inlets and outlets. Trane offers

various hose kit combinations to

sized to handle the required flow with a minimum pressure drop.

Note: Pipe will sweat if low tempera- ture water is below the dew point of the surrounding space. Trane recommends that these lines be insulated to prevent damage from condensation when con- denser loop is designed to be below 60 F/ 16 C. Equipment installed in attic/crawl space temperatures below

40 F/ 4 C may require antifreeze in the water loop.

7.For acoustically sensitive areas, a six- inch deep fiberglass insulation is recommended to be field installed below the horizontal unit. This field supplied insulation should be approximately twice the footprint size of the unit. It provides sound damping of the unit while in operation.

ing. These flexible hoses also aid in

the reduction of vibration between

the unit and the rigid central piping

system.

2.The unit’s (item 2) 3/4-inch high

3.voltage and (item 3) 1/2-inch low voltage connections are located on the left chamfered corner of the unit. They are designed to accept conduit.

4.A field supplied line voltage disconnect should be installed for branch circuit protection. Check local codes for requirements.

5.Trane’s self-contained pump module and hose kit make a complete pump- ing package for distributed pumping systems. The module is designed for circulating commercial loops that require a maximum flow rate of

20 gpm (76 lpm). Each pump module is fully assembled for connection to water and electrical points. The kit contains all of the necessary components for the installation, operation and maintenance of a closed loop application.
