Water Source Heat Pump Piping Diagram

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.

Water source heat pump piping diagram. Water source heat pumps can operate in either cooling or heating mode with a common water loop. The best features of both systems. 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. Water source heat pump applications.

Both zones must operate in the same mode e g heating or cooling at the same time. The water supply may be a recirculating closed loop or a once thru system using water from a well a pond or a stream. As the most energy efficient hvac systems on the market water source heat pumps wshps are uniquely simple in design. From one medium to another.

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. They do this by cycling water through a system of pipes that is laid out at the bottom of a body of water. 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. Heat is moved through an interconnected water loop and either rejected through a cooling tower or put to work in other areas.

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. Selection of a water to water heat pump must be based on the source and load temperatures that occur at design load conditions on a particular project.

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 for closed loop heat pumps is usually circulated at 2 25.
