Electronic expansion valve managed by software, can allow the refrigerant circuit to work very e ciently and reducing the power consumption. When the heating load changes suddenly, a traditional expansion valve experiences a 2-3 minute hunting period before achieving a state of equilibrium. On the contrary we have an immediate action of an electronic expansion valve.

When a compressor starts or stops:

• –  The electronic driver pre-positions the valve at a point that is very close to the nal equilibrium point
• –  The state of equilibrium is quickly achieved with minor adjustments.
• –  The expansion valve becomes an active part within the system instead of just a passive part.
• –  Hunting lasts hardly any time at all.
