AWCL Heading Text
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.
