Water Source Heat Pump Loop Design

Open or closed loop the actual heat pump device utilized is a water to water w w heat pump designed to operate at temperatures appropriate to the source temperatures.

Water source heat pump loop design.

Water source heat pump applications utilize low system return temperatures and most boiler designs such as cast iron and smooth tube cannot operate with system temperatures below 140 f without condensing. Water source heat pump systems are one of the most efficient environmentally friendly systems available for heating and cooling buildings. Water for closed loop heat pumps is usually circulated at 2 25. From one medium to another.

Topics include the latest technologies being used in heat pumps design and control of the water distribution loop and dedicated outdoor air system ground source systems and a review of the requirements in ashrae standard 90 1 that apply to wshp gshp systems. Heat is moved through an interconnected water loop and either rejected through a cooling tower or put to work in other areas. 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. When a non condensing boiler condenses soot is formed which builds up on the heat exchanger and burners and reduces its thermal efficiency.

Water source heat pump wshp and ground source heat pump gshp systems. The heated mixture is then piped to the heat pump and heat exchanged with the refrigerant. 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. 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.

The phrase brine is still widely used to refer to the thermal transfer fluid within a closed loop system due to the fact that salts used to be dissolved. Reversible chillers water to water heat pumps 3 to 40 tons. Conveniently located in eau claire wisconsin water source is in step with the times and with the future. Small to large capacity units deliver chilled or hot water for a fan coil air handler used to pretreat outside air radiant floor heating snow ice melt industrial process control domestic water heating and many other hydronic heating or cooling applications.

Closed loop systems pipe a mixture of water and anti freeze to a water source such as a lake where it flows through coils or heat exchange panels in the water to exchange heat with it. As the most energy efficient hvac systems on the market water source heat pumps wshps are uniquely simple in design. The water supply may be a recirculating closed loop or a once thru system using water from a well a pond or a stream.
