- Condenser: Air-cooled finned condenser, shell-and-tube water-cooled condenser
- Evaporator: Evaporator coils, unit coolers, plate evaporator
- Throttling Device: Thermostatic expansion valve, electronic expansion valve, capillary tube
2. Valve Parts
Refrigeration stop valve, solenoid valve, check valve, four-way reversing valve, high-pressure safety valve, needle valve, ball valve
3. Filter, Liquid Receiver, and Oil Separation Parts
Filter drier, suction filter, liquid receiver, oil separator, sight glass (for refrigerant moisture observation)
4. Protection & Piping Auxiliaries
High-low pressure protection switch, oil pressure differential controller, vibration absorber hose, copper tube, copper nut, insulation cotton, refrigeration oil, various refrigerants (R22/R404A/R410A/R507)
III. Application Scenarios
- Steam Boilers: Food steaming/cooking, chemical heating, heating supply, soybean product processing
- Refrigeration Parts: Cold storage, chiller units, central air conditioning, quick-freezing equipment, industrial ice water machines
Would you like me to prepare a spare parts list based on boiler tonnage (1t/2t/4t) or cold storage capacity (HP)?
