Water for closed loop heat pumps is usually circulated at 2 25.
Water source heat pump piping diagram.
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.
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.
As the most energy efficient hvac systems on the market water source heat pumps wshps are uniquely simple in design.
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.
As the water cycles through it gathers heat from the lake or.
Water source heat pump systems are one of the most efficient environmentally friendly systems available for heating and cooling buildings.
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.
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.
Raypak pool spa residential and commercial hydronic products.
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.
Heat is moved through an interconnected water loop and either rejected through a cooling tower or put to work in other areas.
The water supply may be a recirculating closed loop or a once thru system using water from a well a pond or a stream.
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.
