Working Principle of Constant Temperature and Humidity Equipment

Constant Temperature and Humidity Machines: Intelligent Controllers for Precision Environments

In semiconductor wafer manufacturing, a ±0.5°C temperature fluctuation can cause lithography deviations; during biological sample storage, a ±2%RH humidity drift may compromise viability. Our constant temperature and humidity machines, built on industrial-grade standards, integrate "precision control" and "scenario adaptation" technologies to construct stable micro-environments for high-end manufacturing, scientific research, and special storage scenarios.

I. Core Technical Features: Precise Temperature-Humidity Control for Harsh Requirements

✦ Dual-dimensional Precision Control: Utilizing German Schneider temperature control components and imported humidity sensors, it typically achieves ±1°C temperature control (18-30°C range) and ±5%RH humidity adjustment. Customized models can reach ±0.5°C/±2%RH high precision (e.g., for laboratory-specific applications). Real-time dynamic monitoring of environmental parameters initiates adjustment within 10 seconds of exceeding thresholds, ensuring stability in semiconductor chip workshops and lithium battery pole piece drying.

✦ Full Operating Condition Adaptability: Supports wide-temperature operation from -10°C to 45°C, paired with R-32 (German TÜV certified)/R410A refrigerants to maintain energy efficiency in regions with significant temperature variations. For example, in northern winter laboratories, the equipment automatically activates electric heating compensation to maintain 23°C±1°C constant temperature.

II. Industrial-Grade Energy Efficiency and Durable Design

✦ 20% Energy Saving System Optimization: Equipped with rotary/fully enclosed scroll compressors (Danfoss/Hitachi brands), combined with 0.1mm hydrophilic aluminum fin coils and internally threaded copper tube heat exchange systems, energy consumption is reduced by 15%-20% compared to traditional equipment. In a 300㎡ warehouse, annual power consumption can be reduced by 12,000 kWh, while supporting waste heat recovery technology to further lower operational costs.

✦ All-metal Anti-environment Structure:The body uses electrostatically sprayed sheet metal casing, passing a 48-hour salt spray test, and can operate continuously for 3 years without failure in humid pharmaceutical warehouses or dusty workshops. Wide voltage design adapts to 220V/380V power grids to meet installation requirements in different regions.

III. Intelligent Control and Integrated Management

✦ PLC Intelligent Touch Control System: Standard with a color touchscreen, supporting free setting of temperature and humidity, real-time data display, and fault code alarm (e.g., compressor overload, sensor abnormality). The RS485 communication interface can be connected to the factory MES system for cluster monitoring of multiple units, suitable for central control needs in large electronic factories.

✦ Fully Automatic Operation Logic:After presetting parameters, it starts and stops automatically, goes into standby when target values are reached, and restarts when temperature/humidity exceeds thresholds, requiring no manual intervention. For example, in a vaccine cold storage, the equipment continuously maintains 2-8°C/RH35%-65% while uploading data to a cloud monitoring platform.

IV. Scenario-based Solutions

✦ High-end Manufacturing:Provides ultra-dry environments with dew points < -50°C for semiconductor packaging workshops to prevent chip welding moisture; maintains 25°C±0.5°C/RH45%±2% in precision optical component processing to ensure coating process accuracy.

✦ Medical and Warehousing: GSP-certified pharmaceutical warehouse models precisely control 15-25°C/RH35%-65% through electrode humidifiers and dual-cooling source designs; wine cellar applications combine explosion-proof designs to maintain 12-18°C/RH60%±5% for protecting wine aging quality.

✦ Cultural and Scientific Research: Museum heritage storage uses full stainless steel body models with HEPA filtration systems to control 20°C±1°C/RH50%±3% and prevent calligraphy/painting mildew; plant tissue culture laboratories achieve temperature/humidity fluctuations within ±0.8°C/±2%RH through customized solutions, increasing seedling survival rates to 92%.

V. Certifications and Service Guarantee

Products pass multiple certifications including 3C, CQC, CE, GS, and ISO9001, with core components (compressors, sensors) guaranteed for 1 years. The German team supports 48-hour response, providing full-chain services from "temperature-humidity simulation-energy consumption calculation-after-sales operation" for scheme design and installation.

Constant temperature and humidity equipment is a device that maintains environmental stability through integrated control of temperature and humidity. Its core principle relies on the coordinated operation of four major systems: refrigeration, heating, humidification, and dehumidification, combined with high-precision sensors and intelligent control systems to achieve precise regulation. The specific process is as follows:

● The compressor drives the refrigerant cycle, absorbing heat from the air via the evaporator to lower the temperature.

● When the ambient temperature falls below the set value, the system automatically switches to heating mode (electric heating or heat pump).

2. Dehumidification System

● During refrigeration, the evaporator surface temperature drops below the air's dew point, causing water vapor to condense and drain out, achieving dehumidification.

● Some high-end models use rotary desiccant dehumidification, suitable for low-temperature and low-humidity environments.

3. Humidification System

● When humidity is insufficient, an electrode/ultrasonic/steam humidifier activates to inject moisture into the air.

● Humidification output is dynamically adjusted via PID algorithms to prevent overshooting.

4. Intelligent Control

● Temperature and humidity sensors monitor real-time environmental data and feed it back to the controller.

● The controller coordinates all four systems using PID algorithms, achieving precision of ±0.5°C / ±2% RH.
