What is the defrosting frequency of the thermal shock test chamber?

What is the defrosting frequency of the thermal shock test chamber? This is a problem that some customers will be concerned about, because the cold row in the cold tank of the thermal shock test chamber will be frosted due to the exchange of cold and heat, so the equipment must have a defrosting function to ensure long-term us.
