Basic requirements for refrigerants
Basic requirements for refrigerants
1. Moderate refrigerant pressure: low pressure not lower than atmospheric pressure; The high pressure is not too high;
2. Large refrigeration capacity per unit volume, resulting in small unit size;
3. High critical temperature and low solidification temperature;
4. Low viscosity and density, reducing flow resistance;
5. High thermal conductivity. Improve heat transfer efficiency and reduce heat transfer area;
6. No corrosion to materials and no chemical interaction with lubricating oil;
7. Harmless to the human body, without explosion or combustion.
