Abstract

The invention discloses a temperature rise and humidification control system for a constant temperature and humidity test chamber and a control method thereof. A heater, a humidity sensor, a temperature sensor and an evaporator of the test chamber. A water temperature heater and a water temperature sensor are provided inside the humidification water tank. The interior of the humidification water tank is connected with the interior of the constant temperature and humidity test chamber through a steam pipe. The invention can solve the problems of hysteresis of humidification response, large deviation of humidity overshoot at the initial stage of humidification, and unstable humidity control at low temperature humidity stage, thereby ensuring the reliability of test data.

Description

technical field [0001] The invention relates to the technical field of test chamber equipment, more specifically, to a temperature rise and humidification control system and a control method for a constant temperature and humidity test chamber. Background technique [0002] The constant temperature and humidity test chamber is a kind of equipment that tests the performance of the product under a certain constant temperature and humidity state to test whether the performance of the product meets the requirements of the relevant standards. [0003] During the test, in order to achieve the preset temperature and humidity, the constant temperature and humidity test chamber needs to be equipped with corresponding temperature adjustment devices and humidity adjustment devices to adjust the temperature and humidity. However, the existing constant temperature and humidity test chambers have the following deficiencies: 1. When the humidification operation starts suddenly when rising ...
