Compressor |
“Tecumseh “ made in Germany |
Refrigeration principle |
Steam compress type refrigeration Its principle is to use freon in the latent heat of evaporation of a liquid from cooling objects, such as heat and refrigeration. The expansion valve into the evaporator liquid, absorbing latent heat of evaporation and evaporation from the surrounding objects, evaporate into low temperature and low pressure gas refrigeration compressor suction, compressed by compressor into a high temperature and high pressure gas into the water cooled or air cooled condenser, which cools into a high-pressure liquid, then through the expansion valve into the evaporator. Repeat cycle, heat from the low temperature refrigeration and heat released from the high temperature. |

Refrigerating fluid |
R404A(Ozone depletion index is 0 ) |
Equipment Description:
Walk-in constant temperature and humidity test room is specially suitable for whole machine and large parts to do low temperature
test, high temperature test, high and low temperature change test, constant temperature and humidity test, high temperature and
low temperature test with humidity change test and so on.To provide a large temperature and humidity test room for testing big
size parts,semi-finished product and finished product,at the same time,also be applied in testing large quantity or big size equipment,
such as computer terminal, auto parts,etc.The test room is mainly consist of control panel, distributor, moisturizing base plate blower,
heater, humidifier, refrigerating unit.We also can custom the size chamber size and function, according to customers’ standard and
requirement.Block type appearance,beautiful shape,scientific design,can meet customers’ different requirement.
