Heat Exchanger, Performance Directly Determines The Energy Consumption of Air Conditioning

In the advocacy of national energy saving policy, with the implementation of air conditioner energy efficiency standards, air- conditioning plant even more attention to the level of energy efficiency equipment. Heat exchanger as one of the core components of the air-conditioning, performance directly determines the energy consumption of air conditioning. According to experts, water-cooled heat exchanger efficiency is higher than air-cooled heat exchanger, such as shell and tube heat exchangers heat transfer rate can reach 75%, due to fluid-cooling, the cooling efficiency of plate heat exchanger can reach 95%. In air-cooled heat exchanger, micro-channel, parallel flow condenser in the low-carbon energy saving achieved a major breakthrough. It is understood that the micro-channel heat exchanger has a slightly different with fin condenser, but the structure is completely different, the basic structure of the microchannel heat exchanger for multi-channel aluminum ribbon flat tube, corrugated fins (to open a number of blinds), the overall welding and general multi-tube process. Microchannel heat exchanger is more expensive than ordinary products, but the resulting value is certainly far greater than the money to buy new products. Micro-channel heat exchanger has low wind resistance, high heat transfer coefficient, large effective heat transfer area, compact structure and small size, under the same heat exchange, its volume reduction of more than 35% and the weight reduce of more than 25%. At the same time, the product is lightweight, aluminum design, compact, small size, a significant reduction in system cost, aluminum recycling and reuse is very simple. Coupled with the heat exchanger volume is small, the average lower refrigerant charge of 30%, effectively reducing the environmental damage, and micro-channel design pressure higher, which will help R410A applications.
