In today's world, energy is the material basis for economic development, but also economic and social science, sustainable development constraints. In accordance with the requirements of energy-saving emission reduction, combined with the energy waste in modern, air-conditioning applications in thousands of households, higher than the outdoor air temperature from the air, air-conditioning in order to discharge the waste heat of hot air be used, and the combination of water, such as family life all aspects of the consideration of a heat exchanger can be designed to take advantage of this part of the heat, so as to achieve energy savings at the same time in the hot water can be used (in general day-to-day household wash water), and ultimately to achieve the purpose of energy conservation.
Heat exchanger is to achieve transmission of heat exchange equipment indispensable in the process of chemical production. The design of a heat exchanger from the structure and the utilization of energy and so on to consider different materials heat exchanger design to compare, select and reasonable heat exchanger; from the heat exchanger heat exchanger installation convenience and reasonable cost (economic rationality) is to consider the design of heat exchangers. To design a system and consider the different seasons and areas such as reservoir capacity of design, comparing the different options of heat exchanger reasonable. Designing heat exchanger and water circulation system and this must analysis in heat exchanger system and the feasibility and economic analysis and so on.
Through different comparisons between the programs selected for the serpentine tube heat exchanger heat exchanger system, the heat exchanger serpentine tube heat exchangers more efficient, simple structure, the advantages of lower cost. Through the summer, the temperature of hot water requirements and heat exchanger materials comparison between the economic; aluminum alloy heat exchanger to meet the requirements, because of its light weight, relatively low cost, easy to install. Hot summer weather, air-conditioning always design an air-conditioning - Water Heater cogeneration system, according to one ton of household water use in January, the system can be a month to about 40 degrees can save electricity, the country with a large population of our country, that the energy savings and emission reduction can imagine the heat on.
Key words: heat exchanger design, utilization of waste heat, snake-like tube, the system design.
