Description
Technical field
The invention belongs to the building materials instrument field, relate to a kind of constant temperature humidity chamber, be applicable to the test specimens such as insulation material, coiled material and coating and do temperature, humid test.
Background technology
The control system that constant temperature humidity chamber of the prior art all contains heating system, refrigeration system, humidification system, dehumidification system and makes these system coordination work.Wherein except heating system was comparatively simple, its system was all comparatively complicated, and refrigeration system and dehumidification system generally need to adopt two to overlap independently compressor refrigeration system, and casing also needs preferably thermal and insulating performance, so price is also comparatively expensive.In addition, existing climatic chamber is because its principle limits, and its operating cost is high, power consumption is large, maintenance cost is high; Be the raising control accuracy, the necessary frequent starting of compressor, this will reduce the serviceable life of compressor cooling or dehumidification system.
Summary of the invention
The object of the present invention is to provide a kind of simple in structure, cheap, low and the constant temperature humidity chamber with higher temperatures humidity control accuracy of operating cost.
For achieving the above object, technical scheme of the present invention is as follows: a kind of constant temperature humidity chamber comprises casing, operating room, cooling assembly, heating component, humidification assembly and electric component; Described operating room, cooling assembly, heating component, humidification assembly and electric component all are arranged on the inside of described casing; Also comprise wind circulating system, this wind circulating system is arranged on the top of casing; And be provided with air outlet at the top of casing; Described operating room is located in the casing, is provided with test-piece stand in the operating room; Described test-piece stand is a plurality of HORIZONTAL PLAID screens, from top to bottom separation setting in the operating room; The both sides of described flase floor test-piece stand form air delivery duct and air-return duct; Described heating component is arranged on the air outlet side at casing top.
Related content in the technique scheme is explained as follows:
1, in the such scheme, the front portion of described casing is provided with the chamber door of observation window, and the bottom is provided with feet.
2, in the such scheme, described cooling assembly is located at the bottom in the casing.
3, in the such scheme, also be provided with temperature sensor and humidity sensor on the both sides of corresponding operating room in the described casing.
Principle of work of the present invention: test specimen to be measured is positioned on the test-piece stand in the workpiece chamber of casing, and cooling assembly, heating component, humidification assembly and electric component begin to start; Operating personnel are by observing the test specimen situation in the workpiece chamber with the chamber door of observation window; The both sides of corresponding operating room are provided with temperature sensor and humidity sensor in the casing, have guaranteed that test specimen is under the condition of desired constant temperature and humidity.
Because the utilization of the technical program, the present invention compared with prior art has following advantages:
The present invention is simple in structure, makes assembling easily, and cheap, operating cost is low in the use, and long service life has higher control of temperature and humidity precision.Be applied in the test occasion of insulation material, coiled material, coating and the strict control of other needs temperature and humidity.When temperature was controlled at 10 ~ 35 ℃, humidity was controlled at 45% ~ 80%; When temperature was controlled at 35 ~ 45 ℃, humidity was controlled at 40% ~ 85%.
