Heat Pump CoP

[warren 1981]

If I had a theoretical heat source of 35°C (95°F) what CoP’s would I expect from aelectrically driven vapour compression cycle heat pump to raise the temperature for hot water generation of 55°C (130°F)?

Is there an easy way to actually calculate this?

Are there any associated problems with having a heat source this high?

Also if i had a insulated water tank 1 meter high x 2 W x 2 L say 4000 litres of water @ 35°C (95°F) would I use the Newtons Law to calculate the reduction time of the drop in temperature.

If anybody could help on this it would be much appreciated.

Check if your compressor supplier has a performance table. You can then extract much of the information from there, if you know what to look for.
