How to select the thermal expansion valve？

1. The role and classification of expansion valves<br></br> Expansion valve is an important part of refrigeration system, generally installed between liquid storage cylinder and evaporator. The expansion valve causes the medium temperature and high pressure liquid refrigerant to become low temperature and low pressure wet vapor through its throttling, and then the refrigerant absorbs heat in the evaporator to achieve the cooling effect.

Performance comparison between servo motor and stepping motor

As an open-loop control system, stepping motor has essential connection with modern digital control technology. In the current domestic digital control system, stepping motor is widely used. With the emergence of all digital AC servo system, AC servo motor is more and more used in digital control system. In order to adapt to the development trend of digital control, stepping motor or full digital AC servo motor is mostly used as the executive motor in motion control system. Although they are similar in control mode (pulse train and direction signal), they are quite different in performance and application. This paper compares the performance of the two.

The role of condensing pressure regulating valve

Condensing pressure regulating valve 　　 When the refrigeration device is running, if the condensing pressure is high, the compressor discharge temperature will rise; the compression ratio will increase; the cooling capacity will decrease; The higher the condensing pressure, the greater the above adverse effects. The high condensation pressure is mainly seen in summer. <img src="{{media url=&quot;The_role_of_condensing_pressure_regulating_valve.jpg&quot;}}" alt="" />
