The heatpump compressor has a single phase 2kW compressormotor.
A heatpump always has a part that gives us the heat and a part to extract the heat from "warm" air.
To control everything, there are 4 temperature sensors. 2 for air in and air out (by fan).
The other 2 NTC temperature sensors are mounted to the water heat exchanger input and output to measure hot and cold water.
In the front the water-heat-exchanger.
On the output ports the wires of the NTC's are visible.
On the background, the compressor.
In the cooling gas circuit there are 2 pressostats.
One for Low Pressure (LP) and one for High Pressure protection (HP)
The object pictured is an SHF-4-10L3 4-way reversing valve coil, commonly used in air conditioning systems and heat pumps. This coil is designed for 4-way reversing valves in heat pump systems, such as central air conditioners, to switch between cooling and heating mode. The coil operates on AC220-240V and has a power consumption of 4.5/3.5W. It is a separate component and does not require new piping when replacing in an air conditioner. The SHF brand is known for its durability and reliability.
Then I bought and installed a good 2nd-hand fan to blow the energy into our system.
