Function, to guarantee the continuous operation of system.And low temperature (< 0 DEG C) climate box refrigeration system is generally equipped with defrosting system, but system
The big ups and downs in the temperature inside the box and humidity short time are often led to during defrosting.
In addition, climate box currently on the market does not have low CO generally2Concentration of analog function is unable to satisfy low CO2Concentration examination
Test demand.
Simultaneously as space is smaller in case, it is unable to satisfy the installation of certain examination measuring instruments, and existing climate box is logical
Frequently with insulating plate structure, even if being furnished with observation window, but visibility is not able to satisfy experimental observation testing requirement still.
Therefore, need to develop a kind of multifunctional accurate climate box, fully consider climate box economy and various environment moulds
The coupling of quasi- parameter is controlled to meet wide scope environmental simulation demand, while improving climate box visibility.
