1,430 and 2,088, respectively. Maximum efficiency is achieved
because the Aegis heat pump water heaters simply absorb
and move heat from the surrounding area, eliminating the
need to generate supplemental heat. Depending on the
model, air or water is pulled into the pump and its heat is
absorbed by the CO2; cool air or water is then exhausted.
The refrigerant is pumped through a compressor, increasing
its temperature. At the same time, cool water from the tank
is circulated to the top and draws heat from the heated CO2
inside the condenser coil.
New heat pump technology using CO2 makes it possible to
use electric heat pumps in below-zero temperatures while
providing a comparable total cost of ownership versus natural
gas (even at historically low natural gas prices). Aegis
produces hot water up to 185° with outdoor air temperatures
as low as -4°F with Aegis A (air source) or source water
temperatures as low as +14°F with Aegis W (water source)
with no need for supplemental heat. This makes these heat
pump water heaters highly efficient for optimal energy
savings and lower operating costs in a variety of new and
retrofit commercial facilities.
In fact, Aegis uses about half the electricity compared to a
resistive electrical water heater. It has a high Coefficient of
Performance (COP) of 3.0 – 5.0 on average year-round. A cool
recovery option with the Aegis A, air source heat pump, is
available to simultaneously produce cold and hot water to
further increase COP.
Available in air and water source models, the new Aegis Heat Pumps by
Lync can derive energy from renewable sources, and are engineered for
those facilities that have converted to renewable, sustainably sourced
electricity.
An advanced defrost cycle with electric coil is available with
the Aegis A air source model. This feature eliminates the
need for reverse operation to defrost. Aegis W, the water
source heat pump water heater, can utilize source water
from a cooling plant, resulting in further increased performance
of both domestic and cooling systems.
Additionally, remote operation is possible through a building
automation system (BAS). Facility managers and other authorized
personnel can monitor unit status in real time, record
operational data, check for faults, and change set point and
operating modes through BAS.
