Oceanair installs Sanyo’s carbon-dioxide heat pump

Published:  09 January, 2009

Using carbon dioxide as the refrigerant in this Sanyo heat pump installed by Oceanair enables hot water to be delivered at 65°C.

Sanyo’s Eco carbon-dioxide based heat-pump heating system at the Bristol premises of Oceanair Distribution is the first in the UK. Using carbon-dioxide as the refrigerant in the self-contained outdoor unit enables hot water to be produced at up to 65°C without the need for an electric booster heater.

The 2-stage rotary compressor has an inverter-controlled DC motor and can achieve a COP of up to 3.75.

The outdoor unit supplies heated water to an indoor unit containing a heat exchanger and hot-water tank, which can supply domestic hot water and be directly connected to radiators or an underfloor heating system.

Water can be delivered at different temperatures for DHW, radiators and underfloor heating. Weather-compensation control is standard.

The outdoor unit is precharged with refrigerant and requires only water and electrical connections. The system is compatible with existing radiators and underfloor systems and can be using as a direct replacement for a boiler.
