Water Loop Heat Pump System Design Guide

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.

Water loop heat pump system design guide.

Creating the loop is fairly easy. Heat pump technology is the most innovative efficient solution to meet the ever challenging goals of reducing energy usage and emissions. Guide to energy efficient commercial equipment aceee 1997 water loop heat pump system design guide epri 1992. A continuously operating pump is clearly wasteful.

Section 5 covers the hydronic design the load water portion of the water to water heat pump. Csu design guides on commissioning and controls. Water for closed loop heat pumps is usually circulated at 2 25. From one medium to another.

Of the ground loop or well water system the source water portion of the water to water heat pump. The design and installation of ground source systems should be undertaken with care and attention. The water supply may be a recirculating closed loop or a once thru system using water from a well a pond or a stream. Ashrae self directed learning course fundamentals of hvac control systems.

A water to water heat pump is the most flexible of any geothermal heat pump since it can be applied for space heating. Open loop systems can present particular challenges and will require the services of a specialist. This educational presentation provides an introduction to the design of heat pump water heaters and their applications. A hot water loop uses a small pump to circulate hot water between a water heater and a distant bathroom or kitchen.
