Refrigeration process
Refrigeration compressor - French Taikang fully enclosed compressor
Working method - compressor cooling
Evaporator – High efficiency components with slope evaporator (AC&R compound spoiler type aluminum fins)
Condenser - using water cooling system to facilitate equipment movement, etc
Heat exchanger - ultra-high-efficiency SWEP plate type cold coal cold heat exchange design, which is more efficient than the traditional internal spiral type
Installation process
1. Nitrogen flushing welding process is adopted, high-quality oxygen-free copper pipe is used for low-temperature connection pipeline, and 48-hour high pressure holding and leakage prevention process to ensure welding quality.
2. The pipeline installation adopts the bending process of the pipe bender, and the turning part is not allowed to use elbow welding.
3. The low-temperature pipeline is equipped with shock-absorbing process pipes, and the refrigeration unit adopts shock-absorbing springs and foot pads for shock absorption and noise reduction.
4. The drying filter absorbs residual moisture, particles, impurities, and acidic substances in the refrigeration system.
5. The selection of solenoid valves is mainly based on well-known brands, and solenoid valve welding takes necessary spool cooling protection measures to prevent damage or reduce life.
Refrigerant - original American DuPont environmental protection refrigerant R404a, R23
Safe use conditions of equipment
Venue requirements:
The ground is flat, well ventilated, and free of flammable, explosive, corrosive gases and dust
There are no sources of strong electromagnetic radiation nearby
Equipped with a drain and floor drain near the equipment (within 2 meters of the refrigeration unit)
Ground load-bearing capacity of the site: not less than 500kg/m2,
Leave proper maintenance space around the equipment
A: Not less than 30cm
B: Not less than 50cm
C: Not less than 70cm
D: Not less than 90cm
The device requires a power supply
Voltage allowable fluctuation range: AC (1±5%) 380V/220V
Frequency allowable fluctuation range: (1±1%) 50Hz
The ground resistance of the protective ground wire is less than 4Ω
The user is required to configure the equipment with a comparable capacity air or power switch at the installation site, and this switch must be independent and exclusively for the use of the equipment
The length of the power cord of the equipment is 1.5 meters
Requirements for storage environment
When the equipment is not working, the temperature of the environment should be kept within 0~+35°C (no freezing).
When the ambient temperature is below 0°C, the water remaining in the equipment should be discharged clean to prevent the water in the pipeline from freezing and damaging the pipe
Water quality requirements
Distilled water, pure water, and deionized water are acceptable (resistivity greater than 500Ω·m) (provided by users)
other
Opening the door of the chamber during the test will cause temperature or humidity fluctuations in the chamber
If the door is opened multiple times or left open for a long time during the test, or if the test sample emits moisture, it may cause the refrigeration system heat exchanger to freeze and not work properly
