Gas cooler regulation valve (HPV)

The high-pressure regulation valve is installed between the gas cooler and the liquid receiver. It
regulates the high pressure for optimum COP in transcritical operation.
The driver for the stepper motor valve is installed in the electrical cabinet.
The driver for the HPV is an XEV20D. It gets a signal from the unit controller – see section 2.9 "CO2
