❑

This valve allows very precise and smooth control of the amount of refrigerant flow in the
system. Since the valve is operated by a step motor, the control circuits can open or
close it in very exact amounts, so the degree of heating or cooling  can be changed by
just a little, or changed very quickly or slowly.

(Completely close …… 0 step)

(Full open ................ 480 step)

Fuzzy Control
Fuzzy Control is a controlling system to control electronic refrigerant control valve using
fuzzy logic. It regulates the functions of heating and cooling, as well as some of the
processes inside the unit, by taking account of many different conditions of temperature,
fan speed, etc.  These control circuits work automatically to send just the right amount of
refrigerant through the Electronic Refrigerant Control Valve.
