Refrigeration system: using French Taikang fully enclosed refrigeration compressor unit (or American Gulun compressor)

Refrigeration compressor: In order to ensure the cooling rate and achieve extremely low temperature requirements of the test chamber, the test chamber adopts a stacked refrigeration method

The design of refrigeration systems should incorporate energy regulation technology, which is an effective way to ensure that the energy consumption and cooling capacity of the refrigeration system can be effectively adjusted while the refrigeration unit is operating normally, reducing the operating costs and failure rates of the refrigeration system to a more economical state.

Refrigeration auxiliary components: air-cooled coil condenser, finned multi-stage evaporator. The main refrigeration accessories and control components are imported, such as the American "Aigo" drying filter, the Italian "Castello" solenoid valve, etc;

Refrigerant: R404A is used

Cooling method: air cooling

Installation method: Split outdoor

Heater: finned heat dissipation tube type nickel chromium alloy electric heating method

Humidification system: External humidifier, water addition can be done automatically or manually

The constant temperature and humidity laboratory adopts multi-faceted power consumption and temperature protection measures, with overcurrent protection, switch power overvoltage protection, overheating maintenance, and shrinkage maintenance designed at every key point of the laboratory work. And the actual operation is simplified, the functions are complete, the cost-effectiveness is high, and customers can apply with peace of mind.

Protection devices: no fuse switch, compressor high and low pressure protection switch, compressor overheating, overload, overcurrent protection, refrigerant high pressure protection switch, fault warning system, electronic alarm, leakage protector, fan overheating protection, phase sequence protection, overtemperature protection, exhaust valve, compressed air regulating switch, fuse.

Room structure:

The chamber adopts a combined storage plate structure, which can be easily assembled on the buyer's site

The indoor wall material of the laboratory is SUS304 stainless steel plate, and the outer wall material is high-quality cold-rolled steel plate. The outer surface is electrostatically painted with a light gray white color; 100mm polyurethane foam and high-density aluminum silicate insulation layer in the middle

The workshop floor is made of anti slip patterned steel plate, and the anti slip slope should ensure that the trolley can easily enter and exit the workshop

The laboratory adopts a double door structure, equipped with internal and external handles

Install moisture-proof lighting on the top of the workspace, with one cable lead out hole on each side (which can be sealed when not in use)

The structure of the laboratory should be designed reasonably, manufactured with excellent technology, aesthetically pleasing both inside and outside surfaces, and the stainless steel plates and electrostatic spraying surfaces should be smooth and free of defects such as bumps and scratches.

Studio size: customized according to requirements, with volumes ranging from 1m ³ to 100 cubic meters

Walk in constant temperature and humidity test cabinetPurpose: This laboratory is suitable for adaptability testing of large components of aerospace, automotive, electrical appliances, hardware and other products under high temperature, humidity, and temperature humidity testing environments, as well as screening methods for product analysis and evaluation. It can be used to test large components, assemblies, and complete products, from computers and copiers to vehicles and machines, and can also be used as a testing environment to test the storage life of food and drugs. Technical specifications and parameters:

The walk-in constant temperature and humidity laboratory is designed to meet users' requirements for large volume testing spaces. It can be divided into integral welding and assembly types structurally. Among them, there are over thirty sizes and sixteen types of refrigeration units that can be matched with each other in the assembled type alone.

The walk-in constant temperature and humidity laboratory can be used to test large components, assemblies, and complete products, from computers and copiers to vehicles and machines. It can also serve as a testing environment to test the storage life of food and drugs.
