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.

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. A continuously operating pump is clearly wasteful. This educational presentation provides an introduction to the design of heat pump water heaters and their applications. Open loop systems can present particular challenges and will require the services of a specialist.

The water supply may be a recirculating closed loop or a once thru system using water from a well a pond or a stream. From one medium to another. Cp3 and cp2 for open loop groundwater source heat pumps and surface water heat pump systems respectively. A water to water heat pump is the most flexible of any geothermal heat pump since it can be applied for space heating.

Creating the loop is fairly easy. However doing so in a way that doesn t waste a lot of energy is a little trickier. 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. 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. Section 5 covers the hydronic design the load water portion of the water to water heat pump. Of the ground loop or well water system the source water portion of the water to water heat pump. Ashrae self directed learning course fundamentals of hvac control systems.
