What is the Temperature Range of a Water Source Heat Pump?

The temperature range for the loop water in a water source heat pump system is typically maintained between 65°F and 95°F (18.3°C and 35°C).

Understanding the Water Loop Temperature

Water source heat pump systems utilize a closed or open loop of water to transfer heat. The system's efficiency and proper operation rely on maintaining the temperature of this water loop within a specific range.

According to the reference provided, a supplemental central heat source and heat rejecter equipment are used to keep the loop water temperature stable throughout the year.

• Lower End (65°F / 18.3°C): A supplemental heat source adds heat to the loop if the temperature drops too low, typically during heating season when heat is being extracted from the loop.
• Higher End (95°F / 35°C): Heat rejecter equipment, such as a cooling tower or fluid cooler, removes heat from the loop if the temperature rises too high, typically during cooling season when heat is being added to the loop.

This maintenance ensures the heat pumps connected to the loop can operate efficiently, whether they are extracting heat for heating a space or rejecting heat from a space during cooling.

Temperature Range Summary

Here is a quick look at the typical loop water temperature range:

This specific temperature range is crucial for the effective and efficient operation of the water source heat pump units connected to the loop system.
