COOLING SYSTEM
This equipment is mechanically cooled by a monopolar system. It is realized by an advanced hermetic compressor.
Refrigeration method: single-stage mechanical compressor
It adopts the cold end PID adjustment technology, which can achieve the effect of temperature control through the accurate output of the compressor cooling capacity. The whole process of cooling and maintaining the temperature below normal temperature does not require the participation of the heater, which is completely different from the balance temperature control method of cold and heat, which means the energy saving more than 30%.
This equipment uses the environmentally friendly refrigerant R404A (CFC free) not prohibited by the Montreal Convention or the London Amendments and new US EPA laws. Cooling method: air cooling
Refrigeration auxiliary parts: The main refrigeration parts are imported, such as thermal expansion valve and pressure controller from Danfoss Company in Denmark; filter and oil separator from EMERSON Company in the United States; solenoid valve from Castel in Italy.
Refrigeration Control Checklist
AIR ADJUSTABLE SYSTEM
Air circulation device: built-in air conditioning room, circulating air duct and long axis fan. By improving the blast airflow of the air, the air flow, heating and cooling capacity are increased, and the temperature uniformity of the test chamber is greatly improved.
Air cooling method: multi-stage membrane air heat exchanger
Heating method: high-quality nickel-chromium alloy wire electric heater. (Using non-contact solid state relay control)
CONSTRUCTIVE MAIN FEATURES
Configuration:
Components of the gas handling unit:
Control System
Project | Content |
Controller | 7-inch LCD touch programmable controller |
Touch high-definition screen | The fixed conditions and program conditions can be set arbitrarily, the Chinese screen can be set, and the curing test name and serial number can be set. |
Settable time range | 0—999H59min. |
Programmable mode
|
At the same time, 120 groups of programs with different conditions can be set. In any group of programs, the work can be divided into 1200 segments, and the number of segments can be arbitrarily intercepted to execute the cycle, or the periodic cycle of any segment or group can be performed. |
In each group of programs, up to 1200 different temperature and time sections can be set (each section can be set up to 999h59min). 120 groups of programs can be connected in series at will, and the maximum number of sections can be cycled up to 999 times. | |
Safety | With a power-off memory device, the remaining programs can continue to be executed when the power is restored, and the machine can be reserved to execute the start-up and machine running time. |
Control | Rising and cooling can be used for slope control and curve control, and has the function of self-correcting temperature and humidity reference points. It has the function of PID automatic calculation, which can reduce the convenience brought by manual setting. |
Set up | Touch setting, direct display of position, all conditions are completely automatically locked by microcomputer |
Warning | If there is an error in the setting or operation, a warning signal will be provided |
Output | The controller has a recording signal port output, which can be connected to a temperature and humidity recorder and output a recording curve |
Interface | With standard RS-232 communication interface, long transmission distance, can be connected to PC for control and recording. |
