Water Source Heat Pump Piping Diagram

Water source heat pump systems are one of the most efficient environmentally friendly systems available for heating and cooling buildings.

Water source heat pump piping diagram.

Water for closed loop heat pumps is usually circulated at 2 25. The water supply may be a recirculating closed loop or a once thru system using water from a well a pond or a stream. They do this by cycling water through a system of pipes that is laid out at the bottom of a body of water. Water source heat pumps on the other hand work on basically the same principle as air source heat pumps but they extract heat from a body of water rather than the air.

Water source heat pumps can operate in either cooling or heating mode with a common water loop. A water to water heat pump with a given heating capacity under favorable water temperatures can have less than half this capacity under more demanding conditions. 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. 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 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. As the most energy efficient hvac systems on the market water source heat pumps wshps are uniquely simple in design.

If a system uses water source heat pumps instead of fan coils it can offer the advantages of a four pipe system while relying on a single hydronic piping circuit. As the water cycles through it gathers heat from the lake or. Water source heat pump applications. Figure 1 shows a piping schematic for an air to water heat pump system that provides zoned heating using radiant panels and zoned cooling dehumidification using small air handlers.

Heat is moved through an interconnected water loop and either rejected through a cooling tower or put to work in other areas.
