Introduction to control system of constant temperature and humidity test chamber

Constant temperature and humidity test chamber by air-conditioning ( Heating, cooling) And part of humidification. According to turn the cooling fan installed at the top of the box body, will complete the steam circulation system, air into shell equilibrium box body temperature, environment humidity, embedded by the shell temperature, temperature sensor to collect data and information, to the temperature and humidity controller ( Small information content CPU) To write solve, tempering desiccant-wheel based orders, according to the air heating module, the condenser pipe and stainless steel water trough in heating volatilization module to cooperate with each other. Constant temperature and humidity test chamber of the control system can be said to be the heart of the whole equipment, in the refrigeration, the warm, wet, circulatory system, such as control power. In refrigeration compressor is choose German brand compressor. Composition part by part of high temperature and cryogenic refrigeration system, each part is a relative single refrigeration system. High temperature part of knowing the volatile digestion and absorption in the medium is derived from the part of cryogenic refrigerant of calorific value and the gasification; Part of ultra-low temperature evaporation of refrigerant from the refrigeration target ( The air in the tester) Endothermic reaction for refrigerating capacity. High temperature part and cryogenic part is to use a volatile middle cooler contact, it is part of the high temperature cooler, is also part of the cryogenic cooler. Heating system with completely separate nickel chrome type electric heaters, resistance is big, the resistor temperature coefficient is small, small deformation under high temperature and ageing, itself the heating temperature of 1000 ~ 1500 ℃, long lifespan. Humidifying is constant temperature and humidity test chamber is different from the key part of high and low temperature test chamber, constant temperature and humidity test chamber choose external isolation type, all stainless steel type heating furnace play a volatile type air humidifier. Dehumidification methods choose mechanical equipment refrigeration dehumidification, evaporative cooling to the moisture content of the following, make over saturation moisture content of vapor coagulation dissolution, as environmental humidity is reduced. Central air circulation system consists of high temperature resistant low noise KongDiaoXing motor, leafy type suction filter of the impeller. It presented the tester in air circulation systems. Control system is the key of the comprehensive test chamber, which the decision-making of the tester temperature speed, precision and so on key parameter values. Most of the control panel tester chooses PID control, is also a small number of select PID controller design and phase composition of the control method. Because most of the control system belongs to the scope of the mobile phone software and the part in the application process, generally not prone to problems. The interpretation of the above is the control system of constant temperature and humidity test chamber, hope can help you, if you want to learn more about information of constant temperature and humidity test chamber, welcome to the online consulting service or call the company service hotline ( Website top right corner) For consultation, we will wholeheartedly provide high quality service for you!

What Are the ISTA Standard Tests and ISTA Testing Equipment?
ISTA (International Safe Transit Association) standard tests are globally recognized transportation packaging test procedures designed to evaluate the safety and reliability of products and their packaging throughout the logistics chain. By simulating real-world transportation conditions such as drops, vibration, impact, stacking, and compression, ISTA testing helps identify potential packaging weaknesses before products enter large-scale distribution. ISTA testing equipment—including drop testers, vibration testers, incline impact machines, and compression testers—plays a critical role in accurately reproducing these conditions under laboratory settings. Proper selection and use of ISTA-compliant equipment enable manufacturers to reduce transportation damage, lower return costs, enhance packaging design, and improve customer confidence in product quality and logistics safety.
