Hermetic Refrigerating and Heating Circulators
Summary:
Heating the liquid circulating closed refrigeration cycle apparatus of the system is a closed system with expansion vessel, the expansion vessel and the liquid circulation system is adiabatic and does not participate in the liquid circulation, only mechanical connection, regardless of how the temperature of the circulating liquid, the expansion vessel the media is always kept at room temperature.
Feature:
- No inner loop groove, a small volume of the inner loop (most circulated only within the apparatus volume 6-10L), effective power density (W / L), the rate of warming and cooling quickly, oil demand also smaller.
- Device uses wavy plate heat exchangers, heat exchange area, heat exchange speed.
- A closed liquid circulation throughout: no mist at high temperature volatile, oil is not oxidized or browning; does not absorb moisture in the air at a low temperature, extending the life of the heat-conducting oil, the use of low cost.
