Types of Hose Connections

Installation

(3)A circuit setter provides a means of manually balancing the water flow to the heat pump. This manual in-line balancing method is accurate up to ±20%. In order to determine flow rate, the user must record both handle posi- tion, and differential pressure drop. Then, the user must consult a chart containing both pieces of information and make the necessary adjustments to the circuit setter.

(4)For self balancing flow control, a Option 3: Flexible hoses with ball valves and circuit setter

Hays Measurflo® balancing hose kit provides a constant flow rate over the pressure differential range of 2 to 80 psid. As system pressures change (through the addition of heat pumps, for example) each individual flow con- trol valve will automatically adjust to the new system conditions.

Additional accessories, such as a strainer are recommended for use to eliminate contaminants from entering the co-axial water-to-refrigerant heat exchanger.

Option 4: Flexible hoses with automatic balancing flow control

Cleaning and Flushing

the Water Loop

After the piping system is complete, the flexible hose connectors should be doubled back to complete the water circuit external to the unit (avoiding trash settle-out in the condenser). An extra pipe may be necessary to con- nect the hose kits.

(1)Water circulation system should be filled with clean water using the water make up connections. Note: Air vents should be open during filling.

(2)With the air vents closed, start the circulating pump and then crack the air vents to bleed off the trapped air, as- suring circulation through all compo- nents of the system.

Note: Make up water must be available to the system to replace the volume formerly occupied by the air that is bled off.

(3)With the air vented and the water circulating, the entire system should be checked for leaks with repairs made as required.

(4)Operate the supplementary heat system (boiler) making checks per manufacturer’s instructions. During this operation, visual checks should be made for leaks that may have occurred due to increased heat. Repair as re- quired.

(5)Open the system at the lowest point for the initial blow down (making sure the make up water is equal to the water being dumped). Continue blow down until the water leaving the drain runs clear, but not less than 2 hours.

(6)Shut down pumps and supplemen- tary heat system. Reconnect the hoses placing the water-to-refrigerant heat exchanger in the water circulating sys- tem.

Note: Vents should be open when the pumps and supplementary heat sys- tem are shut down.

GEV, GEH specifications

Trane has long been a leader in the HVAC industry, and their GEH and GEV series of heat pumps are a testament to their commitment to innovation and efficiency. These models are designed to provide substantial energy savings while maintaining exceptional performance, making them ideal choices for both residential and commercial applications.

The Trane GEH and GEV heat pumps feature advanced variable-speed technology, which allows them to adjust their output to match the current heating or cooling demand. This adaptability not only enhances comfort by maintaining a consistent indoor temperature but also leads to significant energy savings by reducing unnecessary energy consumption during partial-load conditions. By running more efficiently at lower speeds, these units reduce wear and tear on components, extending the lifespan of the system.

One of the defining characteristics of the GEH and GEV models is their high SEER (Seasonal Energy Efficiency Ratio) and HSPF (Heating Seasonal Performance Factor) ratings. These ratings demonstrate the units' ability to provide efficient heating and cooling throughout the year, contributing to lower energy bills. The use of R-410A refrigerant is another key feature, as it is both environmentally friendly and efficient, ensuring that these systems meet stringent regulatory standards while delivering reliable performance.

Installation flexibility is another highlight of the Trane GEH and GEV series. These units are designed to work seamlessly with existing HVAC systems, making retrofitting straightforward. Their compact design allows for easy placement, even in tight spaces, without compromising performance. Additionally, Trane's commitment to quality is evident in the construction of these heat pumps, as they are built to withstand harsh weather conditions and provide reliable service year after year.

Moreover, both the GEH and GEV models are equipped with integrated smart controls that simplify operation and maintenance. These controls allow homeowners and facility managers to monitor energy usage, adjusting settings remotely and scheduling maintenance checks to maximize efficiency. This technology not only enhances user experience but also promotes energy conservation through intelligent management.

In summary, Trane's GEH and GEV heat pumps stand out for their variable-speed technology, high efficiency ratings, installation flexibility, and smart controls. These features make them an ideal solution for those seeking a reliable, energy-efficient heating and cooling option, reflecting Trane's dedication to performance and sustainability.
