Water Cooled Heat Pump Operation

The chiller condenser water heat is recovered instead of being rejected to the outside and used as a heat source for a water source heat pump system serving the perimeter spaces.

Water cooled heat pump operation. We cover air to air h. Water cooled chillers are typically intended for indoor installation and operation and are cooled by a separate condenser water loop and connected to outdoor cooling towers to expel heat to the atmosphere. The water supply may be a. Both heat pumps were assumed to supply heat to an energy efficient house in a cold upstate ny climate of 6720 heat degree days.

Water source heat pump systems are one of the most efficient environmentally friendly systems available for heating and cooling buildings. High efficiency self contained units are available in a variety of sizes and configurations and can be placed in virtually any location within a building. The unit s compact footprint allows for easy installation where space is a concern. A geothermal heat pump with an assumed seasonal average cop of 4 0 and a cold climate air to water heat pump with a seasonal average cop of 2 5.

A water source heat pump extracts heat from the water when in the heating mode and rejects heat to the water when in the cooling mode. A heat pump extracts heat from a source and transfers it to a sink at a higher temperature in engineering the term heat pump is generally reserved for equipment that heats for beneficial purposes rather than that which removes heat for cooling only 3 capacity is determined. Definition of a heat pump ashrae handbook 2008. The industry s only water source heat pump with automatic 3 speed fan control provides greater and more versatile comfort control than its 2 speed counterparts an economical approach for comfort conditioning requirements in both traditional and geothermal replacement renovation and new construction applications.

The closed water loop provides condenser water to the interior zone cooling units picking up the heat normally rejected to a cooling tower and transferring it as. The 50pch indoor water cooled heat pump unit with puron refrigerant is designed for horizontal installation with a variety of airflow configurations. Evaporatively cooled chillers offer higher efficiencies than air cooled chillers but lower than water cooled chillers.
