Description
Air-to-water
heat pumps with CO2 gas refrigerant can be used in a variety of sanitary hot
water supply applications. It is the world's first two-stage compressor
(combining rotary and scroll technology). It maintains high efficiency and
significantly improves performance in cold outdoor temperatures.
Heat
pumps take "free" heat from the outdoor air and amplify it to produce
hot water quickly and efficiently. It can generate hot water up to 90°C without
the need for additional immersion electric heaters.
A CO2
heat pump uses a cold refrigerant coil that absorbs "free" heat from
the outside air and a 2-stage compressor that puts the refrigerant under high
pressure to raise its temperature. The onboard heat exchanger uses the heat
from the refrigerant to produce sanitary hot water. It can produce hot water
during off-peak electricity prices and then store it in tanks for use during
the day. CO2 heat pumps efficiently produce large amounts of hot water using
only ambient air heat and a small amount of electricity. A CO2 heat pump is
often used for direct boiler replacement because it controls water supply and
storage temperature and output capacity.
