Particularly: refrigerator is connected respectively successively with the compressor, condenser and the evaporimeter that are installed between test cabinet left side wall and casing left side wall, and this refrigerator, compressor, condenser, evaporimeter are connected to control device; Heater is connected with the drive motors being installed between test cabinet right side wall and casing right side wall, and this drive motors is connected to control device; Humidifier is connected with the water tank being installed between test cabinet right side wall and casing right side wall, and this humidifier is connected to control device.
Blower fan and control device join, and the quantity of blower fan is two, and two blower fans are arranged on respectively the arranged on left and right sides at test cabinet top.
Rack is latticed, and rack is provided with the humidity sensor and the temperature sensor that are connected with control device.
On water pipe, offer some osculums, the end of water pipe connects to water tank through filter; Casing arranges a transparent water-level gauge in the lower right corner, this water-level gauge parallels with the position of water tank.
Further step is: chamber door center position offers an observation window.
By such design, the utility model beneficial effect is: humidifier and water tank are for regulating the damp condition of chamber, lavatory, refrigerator and heater are for regulating the temperature conditions of test cabinet, design science, compact conformation, can set the predetermined value of test environment completely by control device, restart all parts and carry out work, automaticity is high, and Temperature and Humidity Control is accurate, system is used stable, has good experimental condition.
After condensing into water, the air in test cabinet can converge to water pipe by osculum, water pipe also filters flowing to before water tank, water-level gauge can clearly show the situation of current water tank, prevent the situation that causes complete machine to break down because of anhydrous, simultaneously, the water condensing is also recycled, and recycles energy-conserving and environment-protective.
