Installation
　　Equipment installation: Install the main equipment of the air conditioning and ventilation system, such as: chillers, compression condensing units, air conditioners, integral cabinets, split air conditioners, mechanical fan dehumidifiers, defrost heaters, cold storage coolers and other equipment.
Installation of terminal equipment and air duct valve accessories: install the terminal equipment of the air-conditioning system, such as bacteria-type vents, gooseneck vents, shutters, filters, drip separators, air outlet grilles, air distributors, diffusers, The installation of the suction head, etc.; the installation of air pipe valve accessories, such as the installation of fire dampers, shut-off dampers, damper doors, silencers, etc.
　　 duct installation: install air ducts for air-conditioning and ventilation systems, such as return air static pressure box, spiral duct, rectangular duct, thick skin duct, venting parts, etc.
Installation of copper pipes of compression condensing unit: Welding and installation of copper pipes of fluorine system of compression condensing unit, including angle valve brazing and brazing, can also install control valve accessories on copper pipes such as expansion valve, solenoid valve, angle Valves, safety valves, filling valves, etc., and can also be used for thermal insulation of copper pipes.
　　The installation of cold storage board: It can carry out on-site splicing installation of cold storage board and bonding and waterproofing, and assemble and fix shelves in the warehouse.

Test
　　 Air pipe leak detection test: According to the requirements of ship inspection or the ship owner, sample the air leakage rate of some air pipe pipes, and discover and reduce the air leakage of the air pipe in the process to meet the requirements of ship inspection or ship owner.
　　 Pressure test of freon system: pressure, hold and vacuum test the unit and freon pipeline to find out whether the system is intact.
　　 Noise test: Run the unit equipment system and test the noise, check whether the noise value meets the requirements and make improvements.
　　 Air volume test: Use anemometer and other equipment to detect whether the air volume of each system and tuyere meets the design requirements and make improvements.

Commissioning and system startup
　　System inspection: Check whether the relevant cable wiring of each system and unit equipment is correct, whether the relevant water piping system and air piping system are complete and meet the requirements of commissioning; check and verify the current, voltage, resistance and phase balance on the equipment Wait whether it meets the requirements of the equipment manual.
　　 Debugging and pre-start preparation: before starting the equipment, charge the refrigerant and observe the system pressure, the water system recycles and adjusts the water system balance, the air volume balance of the air duct system, etc., and finally the unit system is powered on.
　　 Unit equipment system start-up operation: start and run the unit equipment system and check whether the various operating indicators are normal. After a period of observation, the system is normal and finally the system is delivered.
