6. Easy maintenance   

Self-diagnosis: The control system has a self-diagnosis function, when there is overtemperature, compressor overpressure, overload, fan overload and other faults, the controller displays the cause of the fault in Chinese and gives a detailed solution;

Maintenance: The water channel filter is installed in front of the condenser, which is convenient for regular cleaning and prevents the condenser from being dirty and blocked, resulting in a decrease in the cooling rate or even overpressure protection shutdown;

History: Temperature history and alarm records can be viewed on both the touch screen and the optional PC display.

Second, the relevant standards

3. Box structure

The Test Chamber is composed of four parts: insulated box, refrigeration unit, air supply device, control and safety protection system, which adopts an integral design, and can be used after being installed in place and connected to the power supply on site.

1.1 Cabinet

The cabinet adopts an overall upper and lower structure, with the studio in the upper part and the lower part for the unit system.

The side wall of the Incubator equipment from the inside to the outside is: stainless steel inner wall - external stiffener - insulation material layer - decorative shell

1.2 Shell

High-grade hot and cold plate nano baking paint

1.3 Insulation layer

PU (polyurethane) foaming + ultra-fine centrifugal glass wool composite insulation layer with suitable high temperature resistance and thermal insulation effect, with a thickness of 100mm.

1.4 Inner wall

The inner wall of the box is made of 1.0mm SUS304/2B stainless steel plate, and all seams are continuously welded with TIG to ensure that there is no leakage after long-term testing.

The outer wall of the inner box is welded, and the main position is reinforced.

The inner wall bottom plate is designed with drainage holes to discharge the condensate in the box to the outside of the box.

1.5 box bottom

The channel steel at the bottom of the box is welded and formed, and the load-bearing ≥ is 100kg/m².

Cabinet layout

The upper part of the Test Chamber is directly in front of the box gate, and the rear of the box is the air conditioning air supply system.

Air conditioning and ventilation

Side air supply: The air conditioning box is at the back of the studio, and the circulating fan, heater, copper tube aluminum fin evaporator, humidifier, etc. are installed inside.

One set of 0.1HP stainless steel long shaft motor is installed on the top of the box, and the impeller of the stainless steel centrifugal fan is installed on the top of the air conditioning box, and the air is evenly supplied through the air outlet deflector fixed inside the volute to meet the requirements of temperature uniformity.

gate

Single-opening hinged anti-collision door (left hinge, right handle), door opening size 1000W×1000H mm, rotary hinge to ensure that the door opening angle is not less than 120°;

The door hinges are equipped with reinforced hinges to ensure that they can be opened and closed freely.

An anti-frost electric heating belt is installed on the inner edge of the door, and the control system automatically turns on the heating and defrosting according to the temperature of the studio.

Observation window

A set of multi-layer laminated glass observation windows with a viewing area of 300×400 square meters are installed on the door, and the controller automatically turns on the observation window defogging function when the studio temperature is lower than the ambient temperature.
