Air to water heat pump is common for room heating these days.
But did you heat pump working well till -10 deg c or even -25deg c?
As far as known, air source heat pump has a rated outdoor operating temperature, which is the minimum temperature that the compressor will operate safely at.
When it gets colder outside, the heat pump can extract less heat from the ambient air, heating time take long long long to reach the desired temp. or Even worse, it nerve reach the set point to offer enough warm in the room.
Now OSB EVI heat pump air to water model, this problem will never bother you any more.
You will have warm home even at -25 deg c.
What’s is OSB EVI heat pump air to water?
It is air to water heat pump, but with EVI compressor.
EVI stands for enhance vapor injection, which can be be achieved which are especially useful for heat pumps. By injecting the refrigerant directly into the SCROLL compressor head, the conditions in the refrigerant circuit of the system change. As a result, the osb evi heat pump outlet temperature reaches a flow temperature of up to 60° C even at low outside temperatures. Another advantage is the lower heat loss and the efficiency with decreasing source temperature.
At higher source temperatures, the EVI circuit can be disconnected and thus the heat and heat Cooling capacity of the heat pump reduced by approx. 10% to 25%.
Our OSB evi heat pump air to water range from 10kw, 17kw and 34kw, with R410a EVI compressor, offer maximum 60 deg c hot water anytime any where. What’s more,
Remote control with your room thermostat, weather set point, auto defrosting and so on in bulit.
