Humidity testing Powerful Air Circulator Smooth Airflow Temperature Chamber

Temperature and humidity chamber.pdf

1. Performance

Humidity testing Powerful air circulator smooth airflow Temperature Chamber can simulate both temperature and humidity. Controlled humidity from 10% RH to 95% RH can be maintained within the dry-bulb temperature range of +10°C to +85°C, limited by a 6°C dew point. For lower dew point conditions (low RH or relative humidity at low dry-bulb temperatures), you will need dry air purge or GN2 (gaseous nitrogen) purge. See the humidity range chart on the specification page of each temperature-humidity chamber for humidity range limits.

Cooling System

To ensure the chamber of cooling rate and minimum temperature requirements, the chamber of the refrigeration system cascade refrigeration system consisting of imported compressor, the refrigeration system has a reasonable match, high reliability and easy maintenance.
Refrigeration works: a 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 refrigerant through the condenser isothermally 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.
