CHINA low temperature and humidity box, programmable constant temperature and humidity tester -20 ℃/100L

Introduction

The function of the test chamber is to provide a test environment such as constant high and low temperature humidity and alternating high and low temperature humidity; Including refrigeration system, heating system, humidification/water system, air duct system, control system, system protection device, etc.

Constant temperature and humidity testing machine, also known as environmental testing machine, can accurately simulate low temperature, high temperature, high temperature and high humidity, low temperature and low humidity and other complex natural environments, suitable for electronics, electrical appliances, batteries, plastics, food, paper products, vehicles, metals, chemicals, building materials, research institutes, inspection and quarantine bureaus, universities and other industry units for quality control testing.

Test chamber body

1. Structural form

The integral structure, that is, the test chamber, the refrigeration system, the heating/humidification system, the air conditioning system, the electrical control cabinet, and the refrigeration unit are a whole, the refrigeration unit is located at the bottom of the box, and the electrical control part is placed on the side of the test chamber for easy operation.

2. a box

a) In the air duct mezzanine at one end of the studio, heat/humidifier, refrigeration evaporator, blower motor, fan blade and other devices are distributed; b) The test chamber workshop is made of 1mm thick SUS304 stainless steel plate, and the box shell is made of 1mm thick stainless steel.

Meet the criteria

GB11158、GB10589-89、GB10592-89、GB/T10586-89、GB/T2423.1-2001、GB/T2423.2-2001、GB/T2423.3-93、GB/T2423.4-93、GB/T2423.22-2001、IEC60068-2-1.1990、IEC60068-2-2.1974、GJB150.3、GJB150.4、GJB150.9etc.

Test chamber refrigeration system

Refrigeration principle

The refrigeration part is the main part of the cold source generated by the equipment, which provides the required cooling capacity for the cooling, low temperature and constant temperature of the equipment, and the refrigeration system is automatically turned on according to the different test states of the equipment to provide cooling capacity for the corresponding test process, so as to achieve the purpose of the performance indicators of the equipment.

Refrigeration system components

1. Compressor:The refrigeration system is mainly a compressor, this scheme we use the French Taikang fully enclosed compressor, 2.2, oil separator: whether the compressor has refrigeration oil, will directly affect its life

3. Condensing evaporator:Adopting the Swedish "Alfa Laval" currently in the world

4. Vibration reduction:Compressor spring vibration reduction is adopted, and the overall secondary vibration reduction of the refrigeration system is adopted;

5. Refrigeration evaporator:The evaporator is located in the air duct interlayer at one end of the test chamber and is forced to ventilate by a blower motor

Touch controllers

1. LCD touch panel, screen intercom input data, temperature and humidity can be programmed at the same time

2. It can display the curve, display the set value curve, and the actual running curve;

3. Programmable, program group up to 120 groups;

4. The interface between Chinese and English can be converted;

5. It has the function of date and time adjustment, scheduled start, shutdown and screen lock.
