Simple pretreatment room

Abstract

The invention discloses a simple pretreatment room which comprises a cabin body. An air inlet used for inletting clean air of preset humidity and flow and an air outlet used for exhausting air are arranged in the cabin body. At least one semiconductor refrigeration plate capable of refrigeration and/or heating is arranged on the outer wall of the cabin body. A temperature and humidity sensor is arranged inside the cabin body. The semiconductor refrigeration plate and the temperature and humidity sensor are electrically connected with a controller respectively. A filter device is arranged inside the cabin body. According to the invention, the simple pretreatment room has the advantages of simple structure and low cost, and can provide a constant temperature and/or constant humidity clean cabin body with controllable temperature, relative humidity and background concentration; a stable standard test environment is provided for testing; the influence of environmental factors or other uncertainties on the pretreatment effect can be avoided; and pre-set constant temperature, humidity, background, wind speed, pressure and other pretreatment-required environment requirements can be met.

Description

technical field [0001] The invention relates to the technical field of testing equipment, and more specifically, relates to a simple pretreatment chamber. Background technique [0002] Existing furniture, building materials, toys, automotive supplies and other materials and parts will contain volatile harmful gases such as formaldehyde and volatile organic compounds (VOC). When the concentration of volatile harmful gases exceeds a certain range, it will be harmful to the human body cause harm. [0003] At present, there are many equipments on the market for pretreatment of volatile and harmful gases such as formaldehyde and VOC, but the existing pretreatment equipments have the following deficiencies: 1. Complex structure and high cost; 2. The temperature and humidity of the surrounding environment Environmental factors such as air composition and air composition are easy to affect the pretreatment effect, and cannot meet the preset constant temperature, humidity, backgroun...
