The aluminum air cooling condenser uses air as the cooling medium, and the temperature rise of the air takes away the heat of condensation.In the refrigeration system, the evaporator, the condenser, the compressor and the throttle valve are the four essential parts in the refrigeration system. The general refrigeration principle of the condenser is to suck the compressor into the lower pressure from the evaporator. Working medium steam, and then compress the steam with lower pressure of the compressor into steam with higher pressure, so that the volume of the steam is reduced and the pressure is increased, so that the pressure is increased and then sent to the condenser, where it is condensed into The liquid with higher pressure, after being throttled by the throttle valve, becomes liquid with lower pressure, and then sent to the evaporator, where it absorbs heat and evaporates to become steam with lower pressure, so as to achieve the purpose of refrigeration cycle
The aluminum air cooling condenser is part of the refrigeration system and is also a type of heat exchanger. It can turn gas into liquid and quickly transfer the heat inside the pipe to the air near the pipe. The working principle of the condenser: After the refrigerant enters the evaporator, the pressure decreases, changing from high-pressure gas to low-pressure gas. This process requires heat absorption, so the surface temperature of the evaporator is very low, and then the cold air can be blown out by the fan. The condenser cools the high pressure and high temperature refrigerant from the compressor to a high pressure and low temperature. It is then evaporated through a capillary, in an evaporator.
1. Save. Energy saving is an important indicator of today's air conditioners. It is difficult for conventional heat exchangers to manufacture products with energy efficiency standards such as high energy efficiency grades, and microchannel heat exchangers will be the best choice to solve this problem.
2. Excellent heat transfer performance. As far as household air conditioners are concerned, when the size of the flow channel is less than 3mm, the law of gas-liquid two-phase flow and phase change heat transfer will be different from the conventional larger size. The smaller the channel, the more obvious the size effect. When the pipe diameter is as small as ? 0.5～1mm, the convective heat transfer coefficient can be increased by 50%～100%. This enhanced heat transfer technology is aimed at air-conditioning heat exchangers. Appropriate changes to the heat exchanger structure, process and heat transfer enhancement measures on the air side are expected to effectively improve the energy level of air-conditioning heat exchangers.
3. Enhance potential. Microchannel heat exchanger technology and the potential to promote the manufacture of air-energy water heaters and air conditioners can greatly enhance the competitiveness and sustainable development of enterprise products.
Compared with traditional heat exchangers, microchannel heat exchangers are not only small in size, high in heat transfer efficiency, meet higher energy efficiency standards, but also have excellent pressure resistance, can be cooled by CO2 as a working fluid, and meet environmental protection requirements. Widespread attention from academia and industry. At present, the key technology of micro-channel heat exchangers - the production of micro-channel parallel flow tubes has matured in China, making it possible for the large-scale application of micro-channel heat exchangers.
