CHINA Programmable Humidity Chamber -20~150 ℃/50L

Introduction

The function of the Test Chamber is to provide a test environment such as constant high-low temperature and humidity, alternating high-low temperature and humidity; including refrigeration system, heating system, humidification/waterway 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 complex natural environments such as low temperature, high temperature, high temperature and high humidity, low temperature and low humidity, and is suitable for electronics, electrical appliances, batteries, plastics, food, paper products, vehicles, metals, chemical, building materials, research institutes, inspection and quarantine bureaus, universities and other industry units for quality control testing.

Test box

1. Structural form

Integral structure, that is, the test box, refrigeration system, heating/humidification system, air conditioning system, electrical control cabinet, and refrigeration unit are integrated. The refrigeration unit is located at the bottom of the box, and the electrical control part is placed on the side of the test box. Easy to operate.

2. Box

A) In the interlayer of the air duct at one end of the studio, heating/humidifier, refrigeration evaporator, blast motor, fan blade and other devices are distributed; b) The Test Chamber studio is made of 1mm thick SUS304 stainless steel plate, and enclosure is made of 1mm thick stainless steel.

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. According to the different test states of the equipment, the refrigeration system is automatically turned on to provide cooling capacity for the corresponding test process, so as to achieve the purpose of equipment performance indicators.

Refrigeration system components

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

3. Condensing evaporator: using the current Swedish "Alfa Laval" in the world

4. Vibration reduction: The compressor spring is used to reduce vibration, and the overall secondary vibration reduction of the refrigeration system;

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

touch controller

1.LCD touch panel, screen conversation 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 operation curve;

3. Programmable, the program group can reach 120 groups;

4. Chinese and English interface can be switched;

5. With date, time adjustment, scheduled start, shutdown function and screen lock (LOCK) function.
