Description

A constant temperature and humidity test chamber

technical field

The utility model relates to a constant temperature and humidity test chamber, which belongs to the technical field of experimental equipment.

Background technique

When the constant temperature and humidity test chamber is used for high-temperature and high-humidity tests, because the temperature inside the test chamber is higher than the ambient temperature, the water vapor close to the observation window will condense into water droplets and cover the observation window. When doing low-temperature tests Frost will form on the observation window. At this time, the condition of the samples inside cannot be seen through the observation window. When the test temperature drops, condensation water droplets are easy to adhere to the chamber. To prevent condensation on the top of the test chamber when simulating high humidity conditions Water droplets, the existing constant temperature and humidity test chambers are often equipped with a heating device on the top of the chamber. This heating device can eliminate the existence of condensation water droplets to a certain extent, but it increases the cost and easily leads to inaccurate temperature control.

Contents of the invention

The purpose of this utility model is to provide a constant temperature and humidity test chamber capable of eliminating the influence of condensed water droplets, so as to solve the problems raised in the above-mentioned background technology.

In order to achieve the above purpose, the utility model provides the following technical solutions: a constant temperature and humidity test box, including a box body, the upper part of the box body is fixed with a controller, the lower part of the box body is equipped with a refrigeration mechanism and a water supply device, and the upper end of the refrigeration mechanism is connected to a test Cabinet, the refrigeration mechanism includes a compressor and a condensing system, a cabinet door is provided between the cabinet and the test cabinet, a transparent window is provided on the cabinet door, a water tank is fixed on the outer bottom of the test cabinet, and a humidity chamber is embedded on the inner side of the test cabinet Sensor and temperature sensor, humidification device and evaporation device are connected to the side of the test cabinet, electric heating device is installed above the evaporation device, air circulation device is installed directly above the electric heating device, dew is installed on the cabinet door, inside and top of the test cabinet A scraper, the dew removal scraper is connected to the motor through a telescopic rod, and the motor, refrigeration mechanism, humidity sensor, temperature sensor, humidifier, evaporation device, electric heating device, and air circulation device are all electrically connected to the controller.

Preferably, a heat preservation board is provided on the periphery of the test cabinet.

Preferably, the transparent window is a vacuum double-glazed structure.

Compared with the prior art, the beneficial effect of the utility model is: remove the water droplets condensed on the test cabinet and the cabinet door wall through the dew scraper, and ensure that the situation in the test cabinet can be observed normally through the transparent window. In the process of reducing the humidity, the response speed of reaching the target humidity can be faster, and the temperature control condition can be stabilized, which is beneficial to energy saving, and has low cost and is easy to popularize.
