　　Walk in constant temperature aging room/Main technical indicators

1. Main technical parameters:

1.1 Temperature range: normal temperature~(70) 85 ℃; (Adjustable)

1.2 Temperature fluctuation: ± 0.5 ℃;

1.3 Temperature deviation: ± 3 ℃; (Under no-load conditions)

1.4 Effective Capacity: Customer Requirement

1.5 Room Size: Customer Requirement

1.6 Operation mode: digital constant operation

1.7 Heating power: Depending on the volume

1.8 Installation of power supply: 380V; 50 Hz;

2. Control system and safety protection measures:

2.1 The electrical control design shall refer to the "Code for Design of Low Voltage Distribution" GB50054-95, "Code for Design of Power Supply and Distribution" GB5002S2-95, and "Code for Construction and Acceptance of Grounding Devices in Electrical Equipment Installation Engineering" GB50169-92, in order to standardize the electrical control design.

2.2 Control system integration aging function design. Design a functional control cabinet, where the aging time, temperature, and various operation switches can be operated on one control cabinet; The panel design of the electrical cabinet is aesthetically pleasing and easy to operate.

2.3 The aging process can be fully controlled automatically, with some abnormal self handling functions, making the operation automated and simplified.

a. Cut off the power supply of circulating fans, electric heaters, etc; The aging room will cool down on its own and continue aging. When the total aging time is up, the yellow warning light will light up to indicate that aging is complete.

b. Product over temperature protection control. When the temperature exceeds the aging temperature of the product, the power supply to the product will be automatically cut off to protect it from overheating and aging, which may affect its performance; At the same time, the buzzer will sound an alarm and the red warning light will light up. Normal temperature automatically restores power supply.

c. Heater PID control. It is used in conjunction with SSR, and after the temperature reaches the set temperature, the power of the heater is automatically and infinitely adjusted as needed. The device has no mechanical loss and high indoor temperature stability.

2.4 It has multiple protection functions and is safe and reliable.

a. Electric heating prevents dry burning. When the fan fails or the temperature inside the air duct is too high, the entire power supply will be automatically cut off, and the alarm will sound.

b. The design of electric heating and fan linkage means that the heater cannot be started separately when the fan fails to start.

c. Heater anti MC adhesion design. SSR contactless shutdown, no mechanical action or loss, eliminating accidents.

d. The heater connection uses high-temperature resistant wire.

e. Install explosion-proof lighting indoors to extend the lifespan of light bulbs and prevent them from being damaged by external forces.

f. The warehouse body adopts flame-retardant insulation materials with good insulation performance and high safety factor.

g. Overtemperature sound and light alarm function: In case of overheating during the aging process, the red light will turn on and the buzzer will sound.

3. Room structure and material specifications:

The box material adopts EPS sandwich panel, and the combustion performance of the product meets the requirements of B2 level in the "Classification of Combustion Performance of Building Materials".

3.1 Wall Material: The five sides of the warehouse body are assembled with double-sided color steel insulation panels (EPS computer color), fixed support aluminum beams, and aluminum profile panels with edges; The ground is not treated, and sealed glass glue is applied at the joints to effectively ensure the sealing of the room. Aging products are placed indoors.

Among them, the exterior wall material: wall panel: 0.5mm thick color steel plate;

Ceiling: 0.5mm thick color steel plate;

Door panel: 0.5mm thick color steel plate;

Among them, the interior wall material: wall panel: 0.5mm thick color steel plate;

Ceiling: 0.5mm thick color steel plate;

Door panel: 0.5mm thick color steel plate;

3.2 Door opening setting: W 800 × H 1900mm (single/double door);

3.3 Observation window: 400 × 600mm, tempered glass, installed on the front door, allowing for real-time observation of indoor working conditions during the aging process.

3.4 The heater is placed in the circulating air duct on the aging roof, surrounded by fire-resistant insulation materials. Adopting PID temperature module control, after the temperature reaches the required temperature of the product, the power of the heater is automatically adjusted according to the fluctuation of indoor temperature, and the insulation performance of the insulation board is matched to ensure that the indoor temperature is accurately and stably at the set temperature value.

4. Air conditioning system

The wind duct system complies with the "Code for Acceptance of Construction Quality of Ventilation and Air Conditioning Engineering" GB50243-2002 standard.

4.1 The hot air circulation system adopts the concept of downward supply and upward circulation, with large capacity fans forcing air circulation.

4.2 Wind power is divided into exhaust system and circulating air system. Two systems work independently.

4.3 The exhaust system discharges excess indoor heat to the outside when the indoor temperature exceeds the required temperature of the product

4.4 The exhaust system adopts the design concept of combining air ducts and fans, and the circulating fan continuously circulates the air in the room through convection; Ensure indoor temperature uniformity.
