6.Air conditioning system
(1)Working principle: forced circulation internal circulation, balanced temperature regulation and humidity adjustment method:
That is, the central control system performs amplification, analog/digital conversion, nonlinear correction, and comparison with the set value (target value) of the temperature (wetness) according to the collected temperature (wet) signal inside the box, and the deviation is obtained. The signal is calculated by PID, and the output adjustment signal automatically controls the output power of the heater/humidifier, so that the heating (wet) and heat (wet) in the test chamber are lost to a dynamic balance, and finally reach the constant temperature (wet) purpose.
(2)Air circulation device: long shaft centrifugal fan, long shaft external motor drive;
(3)Air heating mode: Nichrome resistive electric heater with special spiral heat dissipation area; PID+SSR drive control;
(4)air cooling mode: high efficiency diaphragm air heat exchanger;
(5)air humidification: stainless steel steam humidification; equipped with pure water, connected to tap water can achieve automatic water supply.
(6)Dehumidification mode: Surface dehumidification of the cooling light pipe.
7.Refrigeration/dehumidification system
(1)Workmanship and low temperature process
The low temperature connecting pipeline adopts high quality oxygen-free copper pipe, nitrogen-filled welding and high pressure-preserving anti-leakage process to ensure the welding quality. The length, inclination, slope and direction of the pipeline must be strictly calculated to achieve the best cooling effect.
(2)The main refrigeration accessories
a. Refrigeration compressor: the original imported low-noise vortex multi-layer mechanical refrigeration system. This type of compressor should be able to achieve large cooling capacity, low noise, low energy consumption and high efficiency. This equipment uses the German blog refrigeration compressor unit and should be able to operate in a long-term, stable and reliable manner.
b. Refrigeration evaporator: The fin-type evaporator has a heat exchange efficiency of 30% higher than that of the general evaporator, and has the advantages of beautiful appearance, small size, and quick cooling.
c. Oil separator and refrigeration oil
Whether the refrigeration compressor has enough reasonable high-quality refrigerating machine oil will directly affect its life. If the refrigerating machine oil enters the refrigeration system, especially entering each heat exchanger, its performance will be greatly reduced. To this end, the system needs to be equipped with an oil separator, which uses the best performance of the imported oil separator and freezer, and its oil performance and viscosity are the most stable.
d. High efficiency condensing evaporator
Adopting the world's advanced brazed plate heat exchanger, the heat exchanger is composed of several pieces of corrosion-resistant stainless steel sheets which are pressed with adult-shaped corrugations. The adjacent pair of stainless steel sheets have opposite corrugations, and the corrugated back lines intersect each other. A large number of contact solder joints, due to the complex contact cross-network channel, cause turbulence on both sides of the fluid, which improves the heat exchange intensity, while the strong turbulence and smooth stainless steel surface make the inner surface of the brazed plate heat exchange flow path difficult to scale. After using this heat exchanger, not only the system resistance is also reduced, but also the shortcomings of large size, poor heat exchange and low efficiency of the domestic large-scale low-temperature test box can be overcome.
e.Cooling method: air-cooled / water-cooled
f. Refrigerant: R404A meets the requirements of international environmental protection conventions.
