Page 7: Cooling mode, Heating/cooling simultaneously

Commercial heating and cooling systems can be designed so the water/ground source heat pumps work with boilers,
chillers or other technologies to manage load requirements.
•
The W and WLB units simultaneously heat and cool water.
OVERVIEW
Gas absorption heat pumps require
approximately 40% reduced size
well field compared to an electric
heat pump system of similar capacity.
This provides substantial savings
in the up front capital investment
associated with this infrastructure.

Example: Provide space heat for a
building in the winter, simultaneously
provide space cooling for a small
load, such as an IT server room.
Example: Provide space cooling for
areas on the south side of a building;
provide space heating for areas on
the north side of a building.
HEATING/COOLING SIMULTANEOUSLY
•
Instead of using the well field, it is possible to use both the hot and cold water for simultaneous applications.
