Control the cold end solenoid valve and bypass the solenoid valve of the refrigeration system, adjust the refrigerant flow, achieve temperature balance, reduce cold and hot offset, and achieve energy-saving effects. At the same time, make temperature and humidity control more accurate, increase and decrease temperature quickly, accurately control the process, and achieve small overshoot, achieving linear temperature control. The display is clear and intuitive, with a strong three-dimensional sense. The programmable control system is flexible and convenient to operate, with stable performance, more efficient work, and flexible installation methods. It can be installed externally or embedded.
