21 Reduction in capital costs With a low temperature water loop connected to a heat pump chiller on the roof or in the plant rooms, plus a Daikin Altherma 3 WS unit in each apartment linked to Daikin heat pump convectors or fan coil units, the total system will deliver lower carbon emissions compared with a typical heating system. This could reduce a developer‘s carbon offset payments, so delivering a low carbon heating and cooling system makes both excellent environmental and economic sense. Heat pump technology reduces carbon emissions compared with any traditional fossil fuel heating system. But the Daikin Altherma 3 WS goes further to reduce the Global Warming Potential (GWP) of system, as it features Daikin’s Bluevolution technology which uses R-32 refrigerant. R-32 has a lower GWP than other refrigerants typically used in heat pump systems - and less refrigerant is required too - so it‘s more environmentally friendly overall. 1 Based on a block of 277 apartments with a Combined Heat & Power (CHP) system and Heat Interface Units (HIU) with CHP thermal efficiency of 48% and electrical efficiency of 32%, 60% CHP / 40% boiler, compared with a Heat Pump with a SCOP of 3.7 based on SAP2012 Communal air-sourced heat pump Modular system Daikin Altherma 3 WS In-apartment unit with integrated DHW tank (180 l) Compatible with any type of emitter Potential for heat recovery From opposing loads connected to a common water loop Commercial water-sourced heat pump (W/C VRV) Connected to the same water loop Ambient temperature distribution To minimise heat loss and risk of overheating
