Water Loop Heat Pump System Design Guide

The design and installation of ground source systems should be undertaken with care and attention.

Water loop heat pump system design guide.

Open loop systems can present particular challenges and will require the services of a specialist. Guide to energy efficient commercial equipment aceee 1997 water loop heat pump system design guide epri 1992. 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. Creating the loop is fairly easy.

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 continuously operating pump is clearly wasteful. However doing so in a way that doesn t waste a lot of energy is a little trickier. Cp3 and cp2 for open loop groundwater source heat pumps and surface water heat pump systems respectively.

From one medium to another. Of the ground loop or well water system the source water portion of the water to water heat pump. This educational presentation provides an introduction to the design of heat pump water heaters and their applications. 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.

Heat pump technology is the most innovative efficient solution to meet the ever challenging goals of reducing energy usage and emissions. Ashrae self directed learning course fundamentals of hvac control systems. Csu design guides on commissioning and controls. A hot water loop uses a small pump to circulate hot water between a water heater and a distant bathroom or kitchen.
