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, it must be in the off state, and the staff must wear dry ground

4) temperature and humidity chamber at the bottom and around the body to be kept clean, in order to avoid a lot of dust inhalation within the unit generates accidents and reduce performance.
