microchannel heat exchanger is coming!
It is reported that for the refrigeration and air conditioning industry, how to provide a stable, reliable, high energy efficiency products is an important proposition in the field. Simply rely on improving the performance of components in the system (such as the use of high efficiency compressor, high efficiency fan) or increase the area of heat exchanger to improve the energy efficiency ratio of products, is bound to increase the cost of equipment, resulting in a large number of non-renewable resources waste, but also increase the cost of consumer purchase.
The microchannel heat exchanger solves the above problems with its efficient heat transfer performance, compact structure and cost advantages.
At present, microchannel heat exchanger is gradually applied to commercial and household refrigeration and air conditioning industry, and its related research has been paid more and more attention by the industry, and has become a research hotspot in the related field.
According to the introduction of industry experts, the basic structure of micro-channel heat exchanger used for air conditioners is multi-channel aluminum ribbon tube, corrugated fin (open slit), overall welding and general multi-pipe. It has a significant effect in low-carbon energy saving, and has advantages in reducing the manufacturing cost of air conditioning and improving the market competitiveness of products.
Specifically, its advantages are as follows: good thermal conductivity, which can effectively reduce the power of the fan; It is helpful to reduce the amount of refrigerant filling and is very important to the use of combustible natural working medium; Save materials and reduce manufacturing costs; Good corrosion resistance.
However, air conditioning refrigeration market experts also pointed out that there are also key technical difficulties in the research process of micro channel heat exchanger, that is, how to solve the problem of uniform distribution of refrigerant two-phase fluid in the sub-channel when the evaporator is used, the problem of switching operation between the cooling and heating conditions, and the removal of defrosting water.
At present, many domestic air conditioning industry giants are also committed to the research of micro-channel heat exchanger for air conditioners, and has been used in small batch air conditioners, for customer test. In this regard, we are working hard on research and development, the new product will be online soon.
