Chilled Water
Reset
Chilled Water Reset — Chilled water
reset is often a practical means of
reducing energy consumption during
periods of the year when heating loads
are high but cooling loads are reduced.
Resetting the chilled water temperature
increases the evaporator refrigerant
pressure. This increased evaporator
pressure reduces the pressure
differential the compressor must
generate while in the heat recovery
mode. A secondary benefit of chilled
water reset is that it enables the chiller to
produce higher heating water
temperature than would normally be
possible.
