GB/T5170.5-2008 Constant Temperature Humidity Test Chamber Internal 70x90x80

GB/T5170.5-2008 Constant Temperature & Humidity Test Chamber, Internal: 70x90x80

Constant temperature and humidity test box is also known as constant temperature and humidity testing machine, constant temperature and humidity test box, programmable alternating humidity and humidity test box, thermostat or constant temperature and humidity box, used to test the performance of materials in various environments of equipment and test the heat resistance, cold resistance, dry resistance, humidity resistance of various materials. Suitable for electronic, electrical, mobile phone, communication, instrument, vehicle, plastic products, metal, food, chemical, building materials, medical, aerospace and other products testing quality. Conform to the standard: GB/T5170.5-2008, GB/T10586-2006, GB/T2423.1-2008 test A, GB/T2423.2-2008 test B, GB/T2423.3-2006 test Ca, GB/T2423.4-2008 test Db.

product feature:

The constant temperature and humidity test chamber is composed of two parts: temperature regulation (heating, cooling) and humidification. Through the rotating fan installed in the top of the box, the air is discharged into the box to achieve gas circulation and balance the temperature and humidity inside the box. The data collected by the built-in temperature and humidity sensor of the box is transmitted to the temperature and humidity controller (micro information processor) for editing and processing, and the temperature and humidity control instructions are issued. Through the air heating unit, condensing pipe and the tank heating and evaporation unit.

Constant temperature and humidity box temperature regulation is through the box built-in temperature sensor, data collection, temperature controller (micro information processor) adjustment, connected to the air heating unit to increase the temperature or adjust the refrigeration solenoid valve to reduce the temperature in the box, in order to achieve the required temperature control. Constant temperature and humidity box humidity regulation is through the body set humidity sensor, data collection, humidity controller (micro information processor) adjustment, connected to the tank heating element, through the evaporation of water in the tank to increase the humidity in the box or adjust the refrigeration solenoid valve to achieve dehumidification, in order to control the required humidity.

operation:

Through three interconnected systems: refrigerant circulation system, air circulation system, electrical automatic control system.

1. Refrigerant circulation system of constant temperature and humidity test chamber: The liquid refrigerant in the evaporator absorbs the heat of the air (the air is cooled and dehumidified) and begins to evaporate. Finally, a certain temperature difference is formed between the refrigerant and the air. The liquid refrigerant also completely evaporates into the gas phase, and is then inhaled and compressed by the compressor (pressure and temperature increase). After being throttled through the expansion valve (or capillary), low temperature and low pressure refrigerant enters the evaporator to complete the refrigerant circulation process.

2. Air ring system of constant temperature and humidity test chamber: the fan is responsible for inhaling the air from the return air outlet, and the air is sent to the space required by the user through the air supply outlet after passing through the evaporator (cooling and dehumidification), humidifier and electric heater (heating). The sent air mixes with the air in the space and returns to the return air outlet.
