Ozone Tester - Ozone Chamber Temperature Humidity System

Heating:

High-quality explosion-proof nickel-chromium alloy heating wire (high resistivity, small temperature coefficient of resistance, small deformation at high temperature and not easy to embrittlement, self-heating temperature up to 1000-1500 °C, long service life) rapid heat exchange, no hysteresis

Heating wire control:

The solid state relay is used as a heating actuator, and there is no large current fluctuation and impact phenomenon, and the operation is stable.

Heating wire protection:

The heating wire is provided with anti-dry protection to prevent the heater from continuously burning after the circulation fan stops for some reason, causing the heater itself to burn out or other accidents.

Humidification mode:

Steam humidification method: using electronic parallel mode micro-motion humidification system

Humidifying heating pipe:

All stainless steel embedded humidification tube with anti-dry explosion protection protector

Humidification system advantage:

Humidification is rapid, saves water, saves electricity, and allows test products to heat up. The humidification and dehumidification system are completely independent, no need for extra drainage, faster than traditional surface humidification (water tray), high control precision, no scale pollution such as scale and scale, good low humidity performance, water level observation window, and easy cleaning

External water supply:

Distilled water, pure water, deionized water (resistivity greater than 500 Ω·m) (provided by the user, manually added water)

Water storage device:

Drawer-type water tank, located in front of the machine, under the door

Water storage tank capacity:

Use two 15L water tanks + standard automatic water inlet system

Ozone Chamber Refrigeration system

Compressor:

Using French Tecumseh, Germany Bitzer, German bock compressor unit

Evaporator:

High-efficiency components uses a slope type evaporator (AC&R compound spoiler aluminum fins)

Condenser:

Air-cooled system for equipment easy movement, etc.

Heat exchanger

SWEP plate type refrigerant cold and heat exchange design, making higher efficiency compared with traditional internal spiral

Energy-saving device:

Utilizing an electronic expansion valve with throttle control:

1. This system enables active control of the refrigeration system, providing adjustable and optimized output for various modes and operating conditions. In contrast, the original thermal expansion valve had fixed proportional adjustment, limiting its controllability.
2. The electronic expansion valve features cyclic control feedback, with a high-response direct control front end equipped with both temperature and pressure sensors. This setup ensures optimal liquid supply to the evaporator, resulting in excellent cooling capacity across a broader working range for the refrigeration system.
3. Energy savings are achieved through the electronic expansion valve's self-adjustment capabilities and its active adaptation to control cooling capacity output throughout the entire range. This results in a more energy-efficient system.
4. The system's energy-saving design leverages the PID + PWM principles of VRF (Variable Refrigerant Flow) technology to enable energy-efficient operation at low temperatures. In this low-temperature working state, the heater remains inactive. Instead, PID + PWM regulates refrigerant flow rate and direction, controlling the three-way flow of the refrigerant pipe, cold bypass pipe, and hot bypass pipe to automatically maintain a constant temperature in the working chamber. This approach reduces energy consumption by 30% under low-temperature conditions. The technology is based on Danish Danfoss' ETS series of electronic expansion valves, which offer smooth adjustment of cooling capacity to meet varying cooling rate requirements by adjusting compressor cooling capacity accordingly.
