1.mobile food cart structure
mobile food cart has the characteristics of compact structure, convenient installation, strong cooling capacity and good dynamic vibration resistance. Air is used as a cooling condenser, two evaporators, and a set of circuit control system. One horizontal refrigerator and one vertical refrigerator are combined as the medium, and the refrigerant evaporation method is adopted for cooling. The mobile food cart part is divided into two systems, the main components are two compressors, two wind and a set of fresh-keeping and mobile food cart equipment suitable for dining car refrigerators.
2.mobile food cart Working principle
mobile food cart has The R134a refrigerant that has absorbed heat in the evaporator becomes a low-temperature and low-pressure gas, which is sucked by the compressor.Compressed into high temperature and high pressure gas, it enters the condenser to be cooled into liquid, and then throttling through capillary tube to become low temperature and low pressure,The refrigerant coexisting with gas and liquid is sent to the evaporator. When it evaporates, it absorbs the heat Items cool down. The evaporated refrigerant becomes vapor, which is sucked and compressed by the compressor again, and the mobile food cart of the whole process repeats itself.
3.mobile food cart parts
mobile food cart compressor, condenser, throttling capillary tube, and evaporator are the main components. A filter drier is installed in the system to avoid The water in the system freezes in the capillary tube, causing ice blockage: The gas-liquid separator prevents the compressor from being hit by the liquid: the one-way valve is positive.
It prevents high-temperature gas from flowing back to the evaporator from the compressor side when the compressor is stopped, and extends the heat preservation time of the mobile food cart.
4.mobile food cart types of refrigerators
mobile food cart is a direct cooling type, the air in the box is natural convection, and the air sinks to the bottom of the box after being cooled by the evaporator.The air in the upper part rises to the evaporator to cool, and finally reaches the relative balance of the low temperature air temperature in the box. Because it is naturally cooled,
Can greatly reduce the dry consumption of food.
