Adopting throttle electronic expansion valve
1. The active control of the refrigeration system is realized, and the fixed proportional adjustment of the original thermal expansion valve is not controllable. The output can be adjusted in advance and optimized for different modes and operating conditions.
2. Due to the cyclic control feedback of the electronic expansion valve, the front end is a temperature-plus-pressure dual-sensor high-response direct control, which can provide the best evaporator liquid supply, so that the refrigeration system can achieve excellent cooling capacity in a wider working range. Output.
