Fully enclosed design, stepper motor drive 2. From full off to full on in a very short time 3. High accuracy, extremely long life 4. Flow rate change is linear, wide range of cold capacity 5. Continuous cooling capacity adjustment, no liquid hammer phenomenon in the refrigeration circuit 6. Motor and valve integrated, high reliability, ceramic valve plate and valve parts wear resistance 4) Main advantages 1. Realize the active control of the refrigeration system, instead of the fixed proportion adjustment of the original thermal expansion valve. The output can be adjusted in advance and optimally for different modes and conditions. 2. Because the closed-loop control feedback front end of the electronic expansion valve is directly controlled by temperature and pressure dual sensors with high response, the optimal evaporator liquid supply can be provided, so that the refrigeration system can achieve excellent cooling capacity output in a wider working range. 3. Energy saving: Electronic expansion valve full range of self-adjustment + active adaptation to adjust the cooling capacity output, making the system more energy saving |
