Water Loop Heat Pump System Design Guide

A continuously operating pump is clearly wasteful.

Water loop heat pump system design guide.

Creating the loop is fairly easy. Open loop systems can present particular challenges and will require the services of a specialist. A hot water loop uses a small pump to circulate hot water between a water heater and a distant bathroom or kitchen. Water for closed loop heat pumps is usually circulated at 2 25.

This educational presentation provides an introduction to the design of heat pump water heaters and their applications. Guide to energy efficient commercial equipment aceee 1997 water loop heat pump system design guide epri 1992. A water to water heat pump is the most flexible of any geothermal heat pump since it can be applied for space heating. Cp3 and cp2 for open loop groundwater source heat pumps and surface water heat pump systems respectively.

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 source heat pump extracts heat from the water when in the heating mode and rejects heat to the water when in the cooling mode. Of the ground loop or well water system the source water portion of the water to water heat pump. Section 5 covers the hydronic design the load water portion of the water to water heat pump.

From one medium to another. Ashrae self directed learning course fundamentals of hvac control systems. 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 heat source evaporator load for the perimeter zone heat pumps.
