Some reasons on a leak in compressor
if there is a leak for the compressor, what will happen to the climatic chamber?


A leak in the compressor of a climatic chamber can have several consequences, depending on the severity of the leak and the specific type of chamber:


Inability to Maintain Temperature and Humidity: The compressor is responsible for circulating the refrigerant that either cools or heats the chamber. A leak can lead to a loss of refrigerant, reducing its ability to maintain the desired temperature and humidity levels. This can render the chamber unusable for testing purposes.



Fluctuating Temperatures: Even if the chamber can still maintain some temperature control, a leak can cause significant fluctuations in temperature and humidity, making it difficult to achieve and maintain stable conditions. This inconsistency can compromise the accuracy of test results.


Reduced Efficiency and Increased Energy Consumption: A leak can force the compressor to work harder to maintain the set temperature and humidity, leading to reduced efficiency and increased energy consumption.



Contamination of the Chamber Environment: Depending on the type of refrigerant used, a leak can release harmful substances into the chamber environment. This can contaminate the test samples or pose a safety hazard to personnel.



Damage to the Compressor and Other Components: A significant leak can cause damage to the compressor itself, as well as other components of the refrigeration system, leading to costly repairs or replacements.




Environmental Impact: Refrigerants can be harmful to the environment if released into the atmosphere. A leak can contribute to ozone depletion or global warming.



To prevent these issues, it is important to regularly inspect and maintain the compressor and refrigeration system of a climatic chamber. If a leak is detected, it should be repaired promptly by a qualified technician.

Some tips for water cooling system and air cooling system

Last week we have a short talk with some predecessor of cooling experts for our testing chamber products, there are some tips for choosing cooling system when we design our products. In face of the tense competition, we have to double and double check our cost when we do quotation for customer. Cost is the primary element for every supplier to win a project. Materials, techniques( design+engineering),deficiency would be the main elements for cost. Taking consideration of these factors, techniques maybe is the major distinction for every supplier.
Techniques sometimes can settle the score for some enterprises when you compete a contract. Therefore how to get a bid successfully on techniques, that is very important. For climatic testing equipment industry, VA and VE projects is very important for tendering. How to choose water cooling system or air cooling system in customized design is critical important. Here Danble climate engineer manager will give you some tips for choosing cooling system.

First let’s check some refrigerants that restricted by international conventions:
R12: It has a great destructive effect on the ozone layer and has been eliminated by the international community. It cannot be used for any purpose such as export heat dissipation.

R22: Although it is still used in some old equipment, it is destructive to the ozone layer. According to the provisions of international conventions such as the Montreal Protocol, its production and use are gradually reduced, and its export is also strictly restricted. In many developed countries, the import of refrigeration equipment containing R22 has been banned.

Restricted by regulations of specific countries:
R134a: The US Environmental Protection Agency stipulates that after the signing of the final rule on October 5, 2023, the use of hydrofluorocarbons (HFCs) with high global warming potential (GWP) in aerosols, foams, and refrigeration, air conditioning and heat pump products and equipment will be restricted. R134a has a high GWP value. Within the scope of the restriction, the sale, distribution or export of related products and equipment will be prohibited three years after the date of manufacture or import restrictions.

Safety hazards
R290 (propane): It has high flammability and explosion risk, and its safety level is A3. It has great safety hazards during export, transportation and use. Many countries have strict restrictions and regulatory requirements on its use and import, and it cannot be used for heat dissipation outlets at will.
R32: It is less flammable than R290, but it is still a flammable refrigerant. Once it leaks and mixes with oxygen in the air to a certain concentration range, it will burn rapidly or even explode when it encounters open flames, electric sparks or other ignition sources. Its export is also subject to certain restrictions.

Among the exported radiators, the frequency of use of air cooling and water cooling cannot be generalized and will be affected by many factors:
Application scenarios
In the field of consumer electronics: For example, computer CPU radiators, air cooling is used more frequently. Because for most ordinary consumers, such as daily office and light entertainment, air-cooled radiators can basically meet the heat dissipation needs, and they have the advantages of low cost, easy installation, and no need for additional complex water cooling circulation system construction and maintenance. Therefore, the radiators for ordinary desktop computers and laptops exported in large quantities are mostly air-cooled.
In the field of industrial and high-performance computing: In data center servers, high-end industrial control computers and other equipment with extremely high heat dissipation requirements, water-cooled radiators are used more frequently. Since these devices run at high load for a long time and generate huge heat, water-cooled heat dissipation can better maintain the stable operation of the equipment with its efficient heat dissipation performance, and ensure that the computing performance does not decrease due to overheating. Although its cost is high and the structure is relatively complex, it is widely used in such scenarios with strict requirements on performance and stability. Water-cooled radiators are often equipped in related high-performance equipment exported.

In terms of regional differences in the market
Consumer markets in developed countries in Europe and the United States: In ordinary home computers and other products, air-cooled radiators are more accepted and used more frequently. This is mainly because there are many DIY computer enthusiasts in Europe and the United States. Air-cooled radiators are easy to install and replace by themselves, and the local labor costs are high. In case of leakage and other faults, the repair costs of water-cooled radiators are relatively more troublesome and expensive. However, in the fields of high-end e-sports and professional graphics processing equipment, the application of water-cooled heat dissipation is also increasing.
Emerging market countries in Asia: With the rapid development of the e-sports industry, the demand for water-cooled radiators in the export of mid-to-high-end computer systems and related high-performance equipment has grown rapidly, and the frequency of use has a clear upward trend. Consumers are more pursuing the ultimate heat dissipation effect to ensure that the performance of the equipment is fully utilized. However, from the overall perspective of the proportion of quantity, air-cooled radiators still occupy a large share in the export of ordinary consumer-grade products due to factors such as affordable prices.
Transportation and cost factors
Transportation convenience: The structure of air-cooled radiators is relatively simple and compact, and it is not easy to be damaged by bumps, collisions, etc. during export transportation. Therefore, it has more advantages in some large-scale, long-distance export trades that have high requirements for transportation costs and product integrity. From this perspective, the frequency of use is relatively high. However, water-cooled radiators require more proper packaging and protection during transportation due to the presence of water pipes, water tanks and other components, otherwise it is easy to cause component damage and leakage.
Cost factors: The overall manufacturing cost and after-sales maintenance cost of air-cooled radiators are lower. For some price-sensitive export markets, such as low-end computers and small appliances in developing countries, air-cooled radiators are more commonly used, which makes them higher than water-cooled radiators in terms of export quantity and frequency of use.
In general, among the exported radiators, air-cooled radiators are more frequently used in some low-end and ordinary application scenarios, but the proportion of water-cooled radiators in high-end, high-performance and demanding heat dissipation fields is also gradually increasing.
Is the refrigerant used in air cooling or water cooling?
Refrigerant is mainly used in water cooling, but it may also be involved in some special air cooling scenarios. The following is a detailed introduction:
Application in water cooling
In the water cooling system, the refrigerant plays a key role in transferring heat. Water cooling is usually composed of components such as water cooling head, water pipe, water pump, water tank and heat sink. Its working principle is to make the water cooling head in close contact with the heat source (such as computer CPU, server chip, etc.), absorb heat and increase the temperature of the internal refrigerant (common such as deionized water, ethylene glycol aqueous solution, etc.). The heated refrigerant flows in the entire water cooling circulation pipeline driven by the water pump and flows to the heat sink. The heat is dissipated to the surrounding air by using the heat dissipation fins and fans on the heat sink. After the refrigerant releases heat here, the temperature drops, and then it flows back to the water cooling head to continue circulating, constantly taking away the heat generated by the heat source. Therefore, the refrigerant is an indispensable part of the normal operation of the water cooling system and achieving efficient heat dissipation.
Special applications in air cooling
In conventional air cooling radiators, such as the downward pressure or tower air cooling radiators commonly seen on computers, the heat is mainly removed by natural or forced convection of air through cooling fins and fans, and refrigerant is not required. However, in some special air cooling application scenarios, such as the air-cooled condenser part of large industrial refrigeration equipment, the internal refrigeration cycle is actually similar to the principle of the water cooling system, but the final heat dissipation is through air cooling, that is, the fan blows air through the cooling fins of the condenser to remove the heat carried by the refrigerant (common refrigerants such as Freon and ammonia, which circulate in the refrigeration system to achieve heat transfer and exchange). Here, the refrigerant plays a core role in heat transfer in the entire refrigeration and heat dissipation system, but this situation is relatively less intuitive and widely used than in the water cooling system.
In general, refrigerant is a basic and conventional component in water cooling, and it is only used in complex systems involving specific refrigeration and heat dissipation in air cooling.

Be capable and be confident
Write to those people who is struggling for job. According to the employment survey data. there is still 16% people cannot get a job. This includes those young people who have just graduated from college. Graduation means losing jobs, that is the status quo for the Z generation.
Why this occurs in China? Danble cliamte thinks there are a few reasons if we get into the deep investigation. First one is the economic structure level. The industrial structure adjustment has changed. With economic development, the demand for young labor in traditional labor-intensive industries has decreased. Although emerging industries have developed rapidly, their scale and employment absorption capacity are limited, and they have high requirements for talent skills. It takes time and training for young people to adapt to their jobs, resulting in structural contradictions in employment.
Constraints of economic growth model: China's economic growth has long relied on investment and exports, and the employment opportunities created are concentrated in related industries. With the changes in the global economic situation and the intensification of international trade frictions, jobs in the export industry have been affected. At the same time, the inactive consumer market has restricted the development of the tertiary industry such as the service industry, which is the main area for absorbing young people's employment.
Education system level:Education is out of touch with the employment market: The professional settings of colleges and universities lag behind market demand. Popular majors have good employment prospects when they enter school, but may be saturated when they graduate. School education focuses on theory and neglects practice, resulting in insufficient practical ability and problem-solving ability of graduates, making it difficult to meet the employment needs of enterprises.
The phenomenon of academic depreciation has intensified: The popularization of higher education has increased the number of college graduates, academic qualifications have depreciated, and corporate recruitment requirements have increased. Not only academic qualifications but also work experience and professional skills are required. Young college students have insufficient work experience and skills when their academic qualifications have weakened, making it more difficult to find employment.
Youth groups themselves:Biased employment concepts: Some young people are too eager for high-income, good welfare, and stable jobs, focusing on large enterprises, state-owned enterprises, and institutions, and lack interest in small and medium-sized enterprises, private enterprises, and grassroots positions. They have too high expectations for career development and are unwilling to start from the grassroots, and their employment choices are narrow.
Insufficient vocational skills: Schools do not pay enough attention to vocational skills training, and young people themselves lack awareness and motivation to actively improve themselves, and do not actively participate in training and practical activities, resulting in insufficient competitiveness in the employment market.
Lack of entrepreneurial awareness and ability: Influenced by traditional employment concepts, many young people tend to have stable employment, have fear and concerns about starting a business, and lack the funds, technology, management and other capabilities and resources required for starting a business, and lack entrepreneurial experience.
Though there are subjective and objective reasons for the negative employment situation, the neutral advice for personal is to be capable and confident. For enterprise, danblec limate thinks all the enterprises should set no barriers for gentle and ages, people who will sparkle if he is the talent. In danble climate, we hire employees for different positions from age 22-55. Though We are one of climatic testing equipment suppliers in China Asia, people may think this kind of equipments supplier, they should hire more male workers, actually danble climate offer an equal chance to all the people who is suitable for the work, no matter about the age and gentle.
Danble climate takes his social responsibility to contribute for the world. In this aspect, we do much better than some other enterprises in local market. The society set up an intangible wall for all people who trap in the employment more or less, according to some young people and elder employees’ experience. The social state ques has discarded them ruthlessly, whether they believe it or not. Be capable and be confident, and never stop learning something new. ‪@danbleclimate‬ @climatic testing equipments
