Abstract
Environmental test equipment for the cooperative control of salt spray concentration and relative humidity, comprising: a dry salt spray generation system, an air conditioning system, a mixing chamber, a test chamber and an electric control cabinet; in accordance with the principle of conserving salt content and moisture content before and after mixing, the environmental test equipment obtains a salt spray concentration relationship formula and a relative humidity relationship formula between: environmental parameters in the test chamber, dry salt spray environmental parameters in the dry salt spray generation system, and air conditioning environmental parameters in the air conditioning system; after determining environmental test parameters required in the test chamber, the salt spray concentration relationship formula and the relative humidity relationship formula are used to obtain: temperature parameters and relative humidity parameters required to be set in the dry salt spray generation system, and temperature parameters and relative humidity parameters required to be set in the air conditioning system.
