Note:

The following equipment may be pur- chased through the nearest Trane dis- tributor.

!Water Regulating Valve Assembly: The water regulating valve assembly consists of a direct acting valve and a reverse acting valve. The direct acting valve opens in response to an increase in discharge pressure during the cooling cycle. The reverse acting valve opens in response to a decrease in suction pressure during the heating cycle. Water regulating valves should be used where low flow, and low or high fluid temperature conditions could occur.This option is beneficial with open loop systems, but not necessary.

!Motorized Water Valve for open loop systems: The motorized water valve is installed on the return line of the system between the loop

and the loop pump module. This isolation device is a much less expensive and very effective alternative. When the compressor begins running, the valve will open, allowing water to flow through the unit. As the compressor shuts down, the valve slowly closes off. The main purpose of the automatic device is to prevent water hammer, by keeping the pressure raised in the loop system during off cycles.

!Electric Strip Heaters: If the ETL listed strip heaters are used, they can be installed directly inside the TWE air handler. These heaters are rated at 230 volts and provide electric heat for both supplemental and emergency heat requirements. There are a number of heater capacities available.

!Pump Module: The pump module and the hose kit make a complete self-contained pumping package for the earth-coupled heat pump system. These kits contain all the

necessary components for the installation, operation and maintenance of the water circuit of a closed loop geothermal application. Standard pump module features include insulated Grundfos pumps, insulated cabinet, optional cast iron or bronze pumps, 3-way brass valves and the choice of a one or two pump module.

!Hose Kits: The hose kits include two brass, 1-inch male pipe thread (MPT) by barb-fittings, two brass 90 degree 1-inch, MPT by barb- elbows with pressure/temperature ports and 10 feet of rubber hose with 4 hose clamps.

!Sand Filter/Separator: A sand filter/separator helps ensure clean water for the water-to-refrigerant heat exchanger. The recommended strainer is 60 mesh or greater. The strainer keeps particles and debris from entering the system.

GSSD specifications

The Trane GSSD (Ground Source, Self-Contained Direct) is an advanced geothermal heat pump system designed to provide efficient heating and cooling solutions for residential and commercial applications. Leveraging innovative technology, the GSSD utilizes the earth's natural energy to deliver optimal indoor comfort while maintaining a low environmental footprint.

One of the main features of the Trane GSSD is its integrated design, which combines multiple components into a self-contained unit. This simplifies installation and reduces the complexity typically associated with traditional heating and cooling systems. The GSSD is available in various sizes and configurations, making it suitable for a wide range of applications, from single-family homes to large commercial buildings.

The GSSD employs a closed-loop geothermal system that circulates a fluid through underground pipes to exchange heat with the earth. This method allows the unit to draw heat from the ground in the winter and dissipate heat back into the earth during the summer months. The system operates using a heat pump, which efficiently transfers thermal energy, providing consistent indoor temperatures throughout the year.

Key technologies incorporated into the Trane GSSD include variable speed compressors, which enable the unit to adjust its output based on the heating or cooling demand of the space. This leads to improved energy efficiency and reduced operational costs. Additionally, the system employs advanced controls and smart technology that enable remote monitoring and adjustments, ensuring optimal performance at all times.

Another significant characteristic of the GSSD is its environmentally friendly operation. By utilizing renewable energy from the ground, the system significantly reduces greenhouse gas emissions compared to conventional fossil fuel systems. Furthermore, the GSSD is designed for quiet operation, minimizing noise pollution and enhancing occupant comfort.

In summary, the Trane GSSD represents a cutting-edge solution in the realm of geothermal heating and cooling systems. Its self-contained design, advanced technologies, and commitment to sustainability make it an ideal choice for those seeking energy-efficient climate control options. With its unique combination of features and capabilities, the GSSD meets the demands of modern applications while contributing to a greener future.
