Air conditioning compressor: Just like a bicycle pump, it compresses the low-temperature and low-pressure gaseous refrigerant into high-temperature and high-pressure gas. The gas is then cooled and liquefied in the condenser, filtered and dehydrated in the dryer, throttled into low-temperature mist through the expansion valve, and absorbs the heat inside the vehicle in the evaporator to achieve cooling. Finally, the refrigerant is sucked back into the compressor to complete the cycle.
- Compressor of compaction garbage truck: Driven by a hydraulic system, it compresses garbage into a smaller volume to improve the loading efficiency of the garbage truck. The wastewater generated during the compression process is collected in a sewage tank to prevent secondary pollution.
