 Specifications of Stability Humidity and Temperature Control Test Apparatus:

Range – 70 to 150°C 

working principle

Temperature and humidity chamber by a thermostat (heating, cooling) and humidification of two parts. At the top of the cabinets by installing a rotary fan, air is discharged into the tank to achieve gas circulation, balance cabinets temperature and humidity, the built-in cabinet temperature and humidity sensor data acquisition, spread of temperature and humidity controller (Micro information processor) editing process, temperature and humidity control instructions issued by The air heating unit inside the condenser and heat sink together to complete evaporation unit.

Heating system

Far-infrared heating using nickel-chromium alloy heating wire heating speed;
High temperature, low temperature completely independent systems;
Temperature control P · I · D + S · S · R system with channel coordination control;
Temperature control the output power by the microcomputer calculus, to achieve high accuracy and high efficiency power efficiency.

Cooling System

Refrigeration cycle are used against the card if the cycle, which consists of two isothermal and two adiabatic processes, whose process is as follows: a refrigerant through the compressor adiabatic compression to a higher pressure, the power consumption of the exhaust gas temperature, after the temperature of the refrigerant through the condenser and other places in and around medium heat exchange medium heat to four weeks. After the refrigerant flows through the shutoff valve adiabatic expansion work, when the refrigerant temperature decreases. Finally, the refrigerant passes through the evaporator isothermal heat from high temperature object, the object to be cooled so that the temperature is lowered. This loop again and again to achieve the purpose of cooling.
       Design and Application of refrigeration system energy regulation technology, an effective treatment can guarantee but also on energy and cooling capacity refrigeration systems can be adjusted in the case of the normal operation of the refrigeration unit, so that operating costs of the refrigeration system down to a more state of the economy.

energy-saving design

In addition to fully consider the safety of refrigeration units, efficient use of all sectors, but while taking multiple energy saving measures: such as: adjusting the cooling capacity of the refrigeration system, liquid-gas bypass regulation, evaporation temperature regulation, low temperature at any point when the thermostat without heat balance, operating power can be reduced to half, so that operating costs and failure rates of the refrigeration system down to a more state of the economy.
Intelligent automatic transfer system expansion, the load automatically adjust the refrigerant flow + intelligent electric power data value (%) to match heating and cooling (load) Analog output data automatically according to the output value. This design than the traditional design saving more than 30%.

The daily maintenance

1) temperature and humidity chamber refrigeration system is the core of the chamber, please at least once a year to check all of the pipe there is no leakage, etc. in the various joints and welding mouth, if oil leakage should be promptly treated.

2) wet and dry bulb and wet cloth should always check, when the test surface is not clean cloth or harden, or more than 85 ℃ high temperature control, the temperature and humidity control to continue to do before. The accuracy of inspection, if non-absorbent, please replace it related to measuring humidity, the test cloth is generally a replacement in March, when we use a clean cloth to replace the body temperature, should be replaced with a new test cloth and then wash your hands sink clean.

3) When the time arrives to take the test product after product, must be in the off state, and the staff must wear dry, anti-power, moisture gloves handling products.

4) ground temperature and humidity chamber at the bottom and around the body to be kept clean, so as not to produce a lot of dust suction unit accidents and reduce performance.
