Dissolution and crystallization in walk-in cooler

Dissolution and crystallization in walk-in cooler Dissolution and crystallization in walk-in cooler When a solid solute (such as lithium bromide) is placed in a solvent (such as water), the molecules (or ions) on the surface of the solute ) Due to its own vibration and the attraction of solvent molecules, it separates from the surface of the solute and diffuses uniformly into the solvent to...

Supermarket refrigerated showcase ammonia absorption refrigerator

supermarket refrigerated showcase ammonia absorption refrigerator supermarket refrigerated showcase Both absorption refrigerators and vapor compression refrigerators use the heat of vaporization of refrigerants to produce cold energy. The main difference between the two is The former relies on the consumption of heat energy as compensation to achieve refrigeration, while the latter uses the...

The display cooler's air barrier and moisture barrier

The display cooler's air barrier and moisture barrier display cooler Due to the large temperature difference between the inside and outside air, a water vapor partial pressure difference corresponding to the temperature difference is inevitably formed, and the water vapor is formed from the high temperature side with the higher partial pressure. It penetrates into the display cooler with lower p...

display cooler single-stage ammonia absorption chiller cycle process

display cooler single-stage ammonia absorption chiller cycle process The pressure and temperature absorption refrigeration system in the display cooler system is divided into two parts, a high-pressure side and a low-pressure side. The evaporator and absorber belong to the low pressure side. The evaporation pressure is determined by the evaporation temperature. The temperature must be sligh...

display cases Distillation principle

display cases Distillation principle Actually, the rectification process of display cases is carried out in a rectification tower. The area where heat and mass exchange occurs below the inlet of the rectification tower is called the stripping section, and the area where heat and mass exchange occurs above the inlet is called the rectification section. The rectification tower also has a gene...

display cases Distillation principle (two)

display cases Distillation principle In display cases, the refrigerant solution passes through the stripping section to the generator, and exchanges heat and mass with the ammonia vapor generated in the generator along the way. The first is eliminated. Cold, so that the concentrated solution reaches saturation 1, and then is heated in the generator. As the temperature increases, the solutio...

Supermarket refrigerated showcase distillation principle (3)

supermarket refrigerated showcase distillation principle supermarket refrigerated showcase If the refrigerant is in the absorber, if the pressure loss between the evaporator and the absorber is neglected, the absorption process is carried out under the Po equal pressure condition, and the saturated dilute solution of state 3 absorbs the vapor from the evaporator (point 8) It gradually thick...
