A Hybrid Heat Pump works like a regular heat pump. It can be used in a wide range of industries, for example dairies, abattoirs, process industries, fish feed, biogas production, breweries and textile industries.
The first Hybrid Heat Pump was commissioned in 2004. Since then, Hybrid Heat Pumps have over 500.000 hours of sound operation, with exceptional COPs and very high uptime.
The COP of a Hybrid Heat Pump, like all other heat pumps, benefits from a small temperature lift. However, a Hybrid Heat Pump differs from a standard ammonia heat pump in that its COP also benefits from large Δt’s, both on hot and cold side.
We can adjust the concentration of water and ammonia, and in theory we could use a solution with very little ammonia that condenses above 200C at 20 bar. However, there are practical considerations, and for the time being we guarantee delivery of 120C.
No. The working circuit is both oxygen free and pressurized, and we have never experienced corroision issues in a Hybrid Heat Pump.
No. Water and ammonia mixture is actually used as an anti-freeze.
