Three controls on a heat pump
To have safe, efficient and durable heat pumps, you need to have routines. An important routine is to keep track of the phases in a heat pump. Another routine that is good to have is to measure different temperatures on a heat pump.
- Measuring the phases of a heat pump compressor should be done at regular intervals to keep track of the condition of the compressor. There should be no more than 10-12 % between the highest and lowest phases. If it is higher between the phases, it may be an indication that the windings on the compressor have something wrong, which in turn can lead to a compressor failure.
- Is the heating curve set correctly? If the curve is set incorrectly or is set at the factory, the worst-case scenario is that you are burning for the crows.
- To know that a heat pump is getting rid of heat correctly, measure the Delta-T of the hot gas and condenser temperature. If the heat pump cannot get rid of the heat, it has to work too hard and this shortens the life of the compressor in the heat pump. The Delta-T of a heat pump should not exceed 25 degrees!
