CO2 Heat Pump Domestic Hot Water
The CO2 heat pump domestic hot water system is an energy-saving,
environmentally friendly and efficient solution for home heating, cooling and
domestic hot water (DHW).
Carbon dioxide is a natural refrigerant. R744 is non-toxic and
non-flammable, the ozone depletion potential (ODP) is zero, and the global
warming potential (GWP) is as low as 1. Safe, non-toxic, and highly efficient
make it the best refrigerant.
The average COP of a CO2 heat pump system is 5, which means
that for 1 kW of electricity input, it will produce approximately 5 kW of heat
output. Compared with the traditional electric element hot water system, this
reduces the use cost by about 80%.
The heat pump hot water system produces a stream
temperature of 90 °C when the outdoor temperature is as low as -25 °C and the
hot water COP is as high as 3.88.
As an environmentally advanced product, the CO2 heat pump system is an economical and environmentally friendly system. It is
eligible for government awards which will save you a lot of costs.
