1) Danfoss electronic expansion valve. Servo control of refrigerant
flow (that is, cooling without heating, heating Uncooled "static balance" technology) 2) As a new type of control element, the electronic expansion valve
has already broken through the throttle mechanism Concept, it is an important part of the intelligence of the
refrigeration system, and it is also the optimization of the
refrigeration system. Important means and guarantees for real realization. 3) Product features: 1. Fully enclosed design, stepper motor drive 2. From very close to fully open in a very short time 3. High accuracy and extremely long life 4. The flow rate changes linearly with a wide cooling capacity
range 5. Continuous cooling adjustment, no liquid hammer in the
refrigeration circuit 6. The motor is integrated with the valve, with high reliability,
and the ceramic valve plate and valve port parts are wear-resistant damage )main advantage 1. Realize the active control of the refrigeration system, not the
fixed proportional adjustment of the original thermal expansion
valve. control. The output can be adjusted in advance and optimized for
different modes and operating conditions. 2. Due to the closed-loop control feedback front end of the
electronic expansion valve is the temperature and pressure dual
sensor high Responsive direct control, which can provide the best evaporator
liquid supply, so that the refrigeration system The wider working range achieves excellent cooling capacity output. 3. Energy saving: full-range self-adaptation of the electronic
expansion valve + active adaptation to adjust the cooling capacity Out, making the system more energy efficient. |
