Constant temperature and humidity system

Abstract

The invention discloses a constant temperature and humidity system which comprises a constant temperature and humidity chamber, a controller, temperature sensors, humidity sensors, a heating device, a cooling device and an air flow mixing device, wherein the temperature sensors and the humidity sensors are arranged on all side walls of the constant temperature and humidity chamber; the temperature sensors and the humidity sensors detect information of the temperature and humidity in the temperature and humidity chamber in a real-time manner, and sending the detected information to the controller; the controller processes the information sent from the temperature sensors and the humidity sensors, and controls the running of the heating device, the cooling device and the air flow mixing device according to the processing result. The constant temperature and humidity system has the advantages that the air flow mixing device is added, and the controller can regulate the running of the heating device and the cooling device according the internal information detected by the temperature sensors and the humidity sensors. Therefore, when detecting non-uniform temperature or humidity, the controller can effectively controls the running of the air flow mixing device, so as to ensure uniform temperature and humidity in the constant temperature and humidity chamber as soon as possible.

Description

technical field [0001] The invention discloses a constant temperature and humidity system, in particular to a constant temperature and humidity chamber used for performance testing in electronics workshops, belonging to the field of electronic equipment. Background technique [0002] The constant temperature and humidity test chamber is used to test the performance of materials in various environments and to test the heat resistance, cold resistance, dry resistance and humidity resistance of various materials. [0003] The constant temperature and humidity test chamber consists of two parts: temperature adjustment (heating, cooling) and humidification. Through the rotating fan installed on the top of the box, the air is discharged into the box to realize gas circulation and balance the temperature and humidity in the box. The data collected by the temperature and humidity sensors built in the box are transmitted to the temperature and humidity controller (micro information ...
