What is Remote Air Conditioning Unit ?

August 01,2023

When it comes to Remote Air Conditioning Unit, you may be curious; what is it used for? Remote Air Conditioning Unit is used to test and determine the parameters and performance of electronic components such as electrical, electronic and other products and materials under high temperature, low temperature, humidity heat or constant temperature environment changes. It is a kind of test chamber that controls temperature, humidity or other factors within a certain range and maintains that temperature for a certain period of time and it can be used in all kinds of areas. You can use this type of test to measure the useful life of a product or to test its stability in a specific environment over time. The Remote Air Conditioning Unit can test the adaptability of products under different environmental conditions such as high temperature and high humidity/high temperature and low humidity/high temperature/low temperature. Widely used in product testing in industries such as electronics, food, automobiles, rubber and plastics, metals, chemicals, and building materials.

LIB Remote Air Conditioning Unit is divided into two parts, the working room is out separately, the air conditioning provides temperature, humidity, and air circulation. The two parts are connected by pipes. You can either buy the Remote Air Conditioning Unit or buy a air conditioning only, which you can connect to your own test chamber. If your lab space is very small, or you want to put the chamber in a corner for the layout of the laboratory, you can choose LIB Remote Air Conditioning Unit to meet your testing needs

The Principle and Structure of LIB Remote Air Conditioning Unit

The working principle of Remote Air Conditioning Unit can be mainly explained by the two physical parameters of temperature and humidity.


The chamber consists of two parts:

1.Working room

Remote Air Conditioning Unit’s working room is separated from the Air Conditioning. The internal material of the working room is 304 stainless steel with a mirror surface, which can resist high and low temperatures, and can also resist moisture and corrosion; it is durable and has a long service life. On the working room there are also Viewing Window and Sample Shelf. The viewing window is 8cm thick double-layer insulating glass, which is made of toughened glass. There is a conductive film on the inner glass of the viewing window to prevent frosting on the viewing window, and the built-in LED light illuminates the working room for clear observation of specimens. The light control button is located under the controller for easy operation. The test chamber has two SUS304 stainless steel punched sample holders; the standard load of each sample holder is 50KGS; the height of the sample holder is adjustable, and it can also be disassembled directly, which is convenient for testing samples of various sizes and is also conducive to air circulation.

2.Remote Air Conditioning: temperature regulation (heating and cooling) and humidification. Through a rotating fan installed on the top of the chamber, air is discharged into the chamber, which circulates the gas and balances the temperature and humidity in the working room. The data collected by the built-in temperature and humidity sensor of the chamber is transmitted to the controller for editing and processing to achieve the purpose of adjusting temperature and humidity.

① Temperature control

To control the temperature, the test chamber must be able to perform two functions: heating and cooling. In addition, it must be possible to regulate the temperature inside the chamber evenly. Specific air distribution technology in the environmental test chamber guarantees a high temperature uniformity throughout the test chamber, ensuring that all components and surfaces are at the same temperature. The mechanical cooling system of the environmental test chamber is composed of a closed circuit system, and the main components are: compressor, condenser, expansion valve, evaporator.

② Humidity control

In order to control humidity, the test chamber must be able to perform both humidification and dehumidification tasks, and must also be able to achieve an even distribution of humidity in the chamber. Direct humidification is achieved with an electric humidifier, which injects steam through the airflow holes behind the air recirculation fan. The humidifier is controlled by a dedicated algorithm for increased reliability. The test chamber is dehumidified by a mechanical system based on the principle of condensation, using the same mechanical system as cooling. According to this principle, when a cooler object is exposed to a warmer environment, moisture in the air condenses on the surface of the cooler object. The evaporator is the coldest element in the test room, so it will be used with a dedicated section to reduce the humidity level in the test room.

The Advantages and Application of Remote Air Conditioning Unit

The remote air conditioning unit, as the name suggests, is a split-type temperature and humidity test chamber inspired by air conditioning. Its working principle is that the built-in microcomputer receives the data of the temperature and humidity sensor, and sends out instructions to adjust the temperature and humidity, so that the heating unit, the condensation pipe work with the heating evaporation unit to realize the two main functions of regulating temperature (heating or cooling) and increasing humidity.

The remote air-conditioning unit is a solution developed by LIB for small or special-shaped experimental spaces. If your laboratory has a limited space and the space for placing a working room is very small, you can consider using this model. You can also consider this model if your test site is located in a corner and a complete temperature and humidity test chamber cannot be placed in the corner. We specially separate the working room and the control system of the temperature and humidity test chamber, so that the working room can be embedded in a limited space, while the rest of the components can be placed in a relatively loose space, and the two parts are connected by conduits. The size and shape of the working room can be customized according to the wishes of the client.


The test chamber is suitable for reliability testing of national defense, aerospace, industrial automation parts, auto parts, electronic and electrical components, chemical and pharmaceutical industry, food industry and related products under different temperature and humidity conditions. The constant temperature and humidity test chamber is used to test and determine the parameters and performance of electronic products and other materials after high temperature, low temperature, alternating humidity, or constant test temperature environment changes. The chamber has a wide range of uses, and in many industrial products temperature and humidity tests are required, especially for electronic components, home appliances, automobiles, aviation, and even schools for scientific research tests. The chamber judges the quality of the product by detecting the two indicators of temperature and humidity. Its function is to simulate the actual use environment of the sample and test the performance of the sample in such an environment.
