Standard configuration of test box

1 power cord (2 meters) (can also be adjusted according to the user's on-site situation)

1 over temperature protector

1 cable hole (Φ 50) (placed on the left side of the equipment for measurement, equipped with a stainless steel cover)

There is a tempered glass door inside the double-layer outer box door, which is convenient for personnel to operate.

bearing

The load-bearing capacity of the sample rack shall not be less than 20KG/layer

Observation window

One heating wire placed on the door, which automatically opens during wet heat and low temperature tests to prevent condensation and frosting, ensuring that the equipment can observe the test situation inside the box through the observation window even when it is in the open state

light

The box door is equipped with one moisture-proof lighting lamp for easy observation of the test samples inside the box. The lighting fixtures are controlled by switches on the control panel outside the box

Control operation interface

Touch control screen, main power switch, buttons, over temperature protector, timer, etc

machine room

Refrigeration unit, power distribution control cabinet, exhaust fan, etc

Distribution control cabinet

Cooling fan

Distribution board

balance device

The box is equipped with a pressure balancing device to ensure that the pressure inside the box remains basically the same as the outside during heating, cooling, and constant testing, preventing damage to the laboratory body caused by excessive or insufficient pressure inside the box

3、 Air circulation section

fan

The power source for mixing air inside the box is the fan, which mixes the air heated by the heater inside the box and then sends it out of the channel to circulate the air inside the box

Air duct

Including air vents and return vents with air guidance, to achieve efficient heat exchange for the equipment

heater

The main heat source of the equipment provides the necessary heat for heating and maintaining a constant temperature, with a reasonable surface heat load configuration, no open flames, and a long service life

4、 Refrigeration section

The refrigeration section is the main part of the equipment that generates a cold source, providing the required cooling capacity for equipment cooling, low temperature, constant temperature, and humid heat. Depending on the testing status of the equipment, the refrigeration system automatically starts to provide cooling capacity for the corresponding testing process, thereby achieving the goal of meeting the performance indicators of the equipment

compressor

The imported air-cooled compressor is used as the power source for the refrigeration system, and the refrigeration system of this equipment adopts a cascade refrigeration system

heat exchanger

Using finned heat exchangers to provide cooling for the refrigeration system and a place for cold and hot exchange of refrigerant

evaporator

The main cold source inside the box is the main component that exchanges energy between the cooling capacity of the refrigeration unit and the hot air inside the box

throttling device

The combination of expansion valve and capillary tube is used for combined control as the throttling device of this equipment, allowing the state of the refrigerant to be changed after passing through this device

refrigerant

Using green and environmentally friendly refrigerant R404A as the refrigerant medium for this refrigeration system

Humidification section

The humidification part is the main component that generates wet steam in the equipment

It mainly consists of the following parts:

Armored heater

The water level switch

It is the main heat source for generating water vapor, which is heated according to the needs of the equipment to vaporize water and produce the steam required by the equipment

Adopting a float switch with high reliability, it provides signals for controlling the reliable addition of water to the humidifier and preventing dry burning alarms

6、 Safety protection device

The equipment has multiple alarm protection functions such as overheating, fan overheating, overcurrent, compressor overpressure, and overheating. The fault self diagnosis function of the controller ensures that once the equipment malfunctions, the power supply to the main components will be cut off and an alarm signal will be issued, including:

(1) Air switch (to prevent overcurrent and short circuit);

(2) Fan overheating protection (protects the supply fan to prevent excessive fan temperature);

(3) Compressor overpressure, overheating, and overcurrent protection (protecting the compressor from excessive pressure, temperature, and current);

(4) Overtemperature protection (to prevent excessive temperature in the laboratory and protect the test sample);

(5) Local temperature protection in the air conditioning room (to prevent excessive temperature around the heating part and protect the laboratory shell);

(6) Temperature fuse dry burning protector (to prevent boiler from burning due to water shortage);

(7) Water level protection (to prevent water shortage in boilers and water supply tanks);

(8) Fuses (to prevent short circuits in control circuits and lighting circuits);

(9) Cooling water shortage alarm (to prevent cooling water shortage);

(10) Box pressure protection (to prevent damage to the laboratory body caused by excessive pressure inside the box)
