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...

Supermarket refrigerated showcase single-stage vapor compression refrigeration cycle (2)

supermarket refrigerated showcase single-stage vapor compression refrigeration cycle actual supermarket refrigerated showcase The theoretical cycle of the refrigerator cycle ignores some of the existence of subcooling, overheating, regenerative heat exchange and resistance Practical factors are therefore practically impossible. After considering the actual factors, the actual pH diagram of ...

The method of saving the power consumption of commercial refrigeration

The method of saving the power consumption of commercial refrigeration: First of all, commercial refrigeration cannot be bought too much, because the larger the commercial refrigeration, the more power it consumes. Under normal circumstances, it is enough for a family of 5 to buy a commercial refrigeration with a volume of 300 to 400 cubic decimeters. Second, the placement of commercial refriger...

display cases Two-stage compression refrigeration cycle and cascade refrigeration cycle (2)

display cases Two-stage compression refrigeration cycle with incomplete intercooling with one-stage throttling The difference between this cycle and other cycles in the display cases is that the refrigerant is the mainstream After being subcooled by the coil-type intercooler, it is further subcooled by the return heat exchanger; the refrigerant vapor from the evaporator is superheated by th...

Supermarket display cases New analysis of industry technology

Supermarket display cases Compressor is the heart of the refrigeration system. It sucks in low-temperature and low-pressure refrigerant gas from the suction pipe. The motor drives the piston to compress it and discharges high-temperature and high-pressure to the exhaust pipe. The refrigerant gas provides power for the refrigeration cycle, thereby achieving compression condensation expa...
