Households with central air-conditioning of the basic types and applications


Put the air conditioning arrangement of housing construction in the early in the planning, so that treatment can solve story problems. However, if this implementation, speaking for the average home buyers, buy a house costs from the market point of view has been quite high, and many are implementing a mortgage payment, if also install central air conditioning, then it will take over the family capacity. For most refrigeration and air conditioning phases 1, 2004 average residential user, because the system requirements on the story, making the loss of this type of air conditioning may be selected. Therefore, the current system is not widely used in China. It is more suitable for high-paying family villa. The VRV system has obvious performance advantages, it is technologically advanced, energy efficient heating and cooling fast, wide range of application, comfort, reliable performance, less maintenance, are high-tech innovative products, and now this model has a large R & D space, we can say, VRV air conditioning technology of the future direction of technology development. However, due to the reasons for the price of this system is currently very difficult to promote, market share occupied by low. Presumably in the last 2-3 years time, it is household proportion of central air conditioning will not be a leap of change. However, with the air conditioning industry, technology development, product price reduction, the improvement of people's income, I believe this system will have an enormous market. For wind cold / hot water unit, the air cooled type small home central air conditioners use a host with multiple terminal devices (fan coil), to meet the requirements of multi-room residential air conditioning,[link widoczny dla zalogowanych], refrigerant charge small amount to reduce the possible leakage of refrigerant to the environment caused by pollution and maintenance costs resulting from,[link widoczny dla zalogowanych], the unit can be used microcomputer automatic control, simple operation, independent control of each room, but also centralized control, convenient and practical, easy to Section electricity. Most end users of central air-conditioning equipment, fan coil units is preferred, because the coil forms, according to owner preferences, functionality, interior decoration to choose, and Security (Continued from page 5 air-conditioning system must be taken to DC-style, not the return air and ventilation to maintain a reasonable number and is similar to \In this way can solve the pollution problems of formaldehyde. 5, Conclusion of formaldehyde on human anatomy is very serious air pollution in the classroom a long time, jeopardizing the health of teachers and students. Anatomy of the classroom air quality is a matter of anatomical techniques,[link widoczny dla zalogowanych], autopsy facilities,[link widoczny dla zalogowanych], ventilation and air conditioning, environmental monitoring, building, structure, complex issues such as professional, so far, lack of multi-disciplinary systems, in-depth study, more of such ventilation and air conditioning Engineering or ineffective, easy to install, reliable, and can be integrated with the interior decoration as a whole. The system's outdoor unit located in the balcony, the noise barrier on the outside. And not subject to the restrictions storey, while the price acceptable to most people, maintenance and operation costs are lower. Based on the above factors,[link widoczny dla zalogowanych], the current account with the central air-conditioning in our wide range of market applications. Of course, since each system has its own characteristics, in the construction, the specific circumstances of each project should be carried out economic, technical and other aspects of analysis and comparison, and finally determine the air-conditioning for engineering programs, remember to follow blindly.
