Screw Compressor parts Working principle: In a screw compressor one of the shafts is driving shaft and the other is driven shaft. working principle A large amount of air discharged from the air compressor flows through the compressed air inlet pipe and enters the running tower in the two towers through the valve, where the moisture is absorbed by the adsorbent and dried. Liquid refrigerant in the evaporator absorbs the heat in the water and began to evaporate, eventually formed certain temperature difference between refrigerant and water, after the liquid refrigerant also completely evaporate into a gas compressor suction and compression (pressure and temperature increase), gaseous refrigerant absorbs heat through the condenser (air/water), condenses into liquid, through the thermal expansion valve or capillary throttle into low temperature low pressure refrigerant entering the evaporator, after completing the process of refrigerant cycle. This is all about centrifugal compressor principle, working, construction, types, advantages, disadvantages with its application. Sleeve bearings are used as shaft seals within the compressor. Must prevent moisture and dirt in the refrigeration cycle (such as oil, iron, copper scrap) to enter, main sources of water is the newly added refrigerant and lubricating oil contain trace moisture, or because the maintenance system of air into the water. How a Scroll Compressor Works Unlike reciprocating technology with many moving parts, the Copeland scroll compressor has one scroll or spiral orbiting in path defined by a matching fixed scroll. It also discusses scroll compressor … In the process of refrigeration, the condenser ACTS as an output heat and condenses the refrigerant. 100% Oil-free (TUV Certification ) Quiet, really very quiet! The vane geometry may be involute, archimedean spiral, or hybrid curves. 8~12 Bar. s.parentNode.insertBefore(hm, s); In order to ensure that the evaporation process can be carried out in a stable and lasting way, the evaporative gas must be pumped out continuously by the refrigeration compressor to maintain certain evaporation pressure. })(); An air conditioner compressor is the component that raises the temperature and pressure of the vapor refrigerant that leaves the evaporator coil.
