How to control the temperature inside the high and low temperature damp heat test chamber?

The high and low temperature damp heat test chamber provides a simulated environment for user inspection and testing.
repeat) provide * conditions
.

The product has simple operation performance and reliable equipment performance, advanced and convenient operation measuring device, high degree of structural integration, scientific air circulation design, uniform indoor temperature and humidity, avoiding any dead angle; complete safety protection device to avoid Avoid any potential safety hazards and ensure the long-term reliability of the equipment.
Next, Dongguan Aipei Testing Equipment Co.
, Ltd.
, which specializes in the production of high and low temperature humidity and heat test boxes, will explain to you one by one about the temperature inside the high and low temperature humidity and heat test boxes.
controlling? There are two main methods, see the following for details: (1) Heating control 1.
The high and low temperature damp heat test chamber is mainly heated by the heating device
.

2.
Heating device: 1.
The electrical appliance relies on the input voltage of the controller, and the input voltage is about 3-12 volts; 2.
The AC end of the wire is connected; 3.
The voltage at both ends of the heater makes the suction contactor heat; 4.
High and low temperature The damp heat test box is driven by a circulating fan to bring heat into the box to heat up
.

 　　3.
When the temperature is about to reach the set value, the controller will adjust the on-off by adding the solid state relay 
.

 　　4.
Adjust the calorific value: 1.
The temperature control above 89 degrees mainly depends on the high and low temperature damp heat test box to see the heating output on the screen to adjust the calorific value; 2.
The temperature control below 89 degrees: ① How much heating output is through the solid state relay on one side; ②Dynamic equilibrium is achieved by cooling the compressor refrigeration cycle, and the temperature is constant
.

 　　(2) Cooling control 1.
The judgment of the performance of the high and low temperature damp heat test chamber is mainly based on the cooling capacity; 2.
The high and low temperature damp heat test chamber consists of four components: compressor, condenser, throttling device and evaporator; 3.
Compression The machine inhales low-temperature and low-pressure gas, and turns it into high-temperature and high-pressure gas, which is the main component of the refrigeration system; 4.
The heat is released by condensing into liquid, and the fan takes away the heat, resulting in hot air under the high and low temperature humid heat test box, and then throttling to low pressure liquid, Secondly, it becomes low-temperature and low-pressure gas through the evaporator, and then returns to the compressor; 5.
The refrigerant absorbs heat in the evaporator to complete the gasification process and absorb heat to achieve the purpose of refrigeration, and complete the cooling process of the high and low temperature humid heat test chamber
