Introduction to structural design
● This high and low temperature humidity and heat test equipment is made of high-quality materials and processed with advanced processing equipment. The surface of the molded shell is spray-coated to make it beautiful and smooth. The colors are coordinated and the lines are smooth and natural. The inner tank is designed as a closed space and is made of high-quality stainless steel plates.
&#;The equipment shell is made of high-quality steel plate CNC machine tool processing and molding. The surface of the shell is spray-painted to make it smoother and more beautiful;
&#;The inner tank is made of high-quality stainless steel plate;
&#;Insulation Material: High-density fiberglass cotton ensures thermal insulation performance and maintains a balanced and stable indoor temperature;
&#; The observation window is made of multi-layer hollow tempered glass with a glued sheet-type conductive film on the inside, which is transparent, heat-insulating, and not prone to steam frosting, etc. Advantages;
&#;The stirring system uses a long-axis fan motor and a stainless steel multi-wing impeller that is resistant to high and low temperatures to achieve strong convection and vertical diffusion circulation to make the temperature and humidity in the laboratory uniform and stable
&#; Double-layer high-temperature-resistant high-tensile sealing strips are used between the door and the box of the equipment to ensure the sealing of the test area. The inner panel of the door is made of stainless steel and adopts a non-reaction door
The handle is easier to operate
&#;The box is equipped with a sample display rack for customers to place test items
&#;The test hole (left side of the machine) can be connected to an external test power cord or a silicone rubber sealing layer test hole
Use the number line (the hole diameter or number of holes can be according to the customer's instructions);
&#; The refrigeration system is installed at the bottom. The compressor adopts Taikang brand imported from France to ensure refrigeration effect and reliability
● High-quality fixed movable wheels are installed at the bottom of the machine to easily move the machine to the designated position and finally move it
Casters are fixed
&#;The control part of the equipment is designed on the right side of the equipment, with temperature controllers, control switches, etc., which are easy to operate, simple and easy to maintain;
● The humidification system is designed at the rear of the box to ensure humidification Effect reliability.
Control system
&#;The temperature and humidity controller adopts digital display R instrument imported from South Korea
Direct digital display of temperature and humidity values and easy key input operation;
Accuracy: .℃ (display range ); Resolution: &;.℃;
&#;Temperature sensor: platinum resistance temperature and humidity sensor;
&#;Control method: thermal balance temperature and humidity control method;
& #;Temperature and humidity control adopts .＋..R system co-channel coordinated control instrument
&#;It has an automatic calculation function that can immediately correct the temperature and humidity changing conditions to make the temperature and humidity control more accurate and stable;
&#;The return air outlet of this test chamber has an automatic defrosting device (so that the water vapor generated during the test will not accumulate on the refrigeration evaporator and cause ice blockage).
Heating and humidification system
● The heater adopts porcelain frame nickel-chromium wire electric heater. This heater has small thermal inertia
and long life. The controllable pulse duty cycle signal output by the instrument is controlled through the solid state relay to achieve smooth and reliable control.
● High temperature completely independent system does not affect low temperature, damp heat test porcelain frame nickel chromium wire electric heater
● Steam boiler electric heating and humidification method armored electric heating tube control method uses non-contact periodic pulse width modulation R (Solid state relay) control is equipped with a water level control device and a heater anti-drying device
&#;Temperature and humidity control adopts . Microcomputer calculation to achieve high-precision and high-efficiency electricity efficiency.
&#;In order to ensure the safe operation of the system, high-voltage control, overpressure, overload and other protection systems need to be installed in the system. At the same time, in order to monitor the operation of the system, a high-voltage meter must be installed at the high-voltage end to monitor the operation of the system.
Refrigeration system
&#;Compressor: fully enclosed French Taikang refrigeration compressor;
&#;Refrigeration method: mechanical refrigeration
&#;Condensation method: forced air cooling< br/> &#;Refrigerant: R (environmentally friendly)
&#;The entire system pipeline is subjected to ventilation and pressure leak detection tests. French Taikang refrigeration compressor
&#;Heating and cooling system Completely independent
&#;Inner spiral refrigerant copper tube;
&#;Slope evaporator;
●Other refrigeration components are made from the United States, Switzerland, Denmark, and Italy
/>, Japan's Saginomiya and other original imported brand-name products.
Protection system
