Hvac development follows the principle is: energy saving, environmental protection, sustainable development, guarantee the health and safety of building environment, to adapt to the national energy structure adjustment strategy, carry out the policy of hot and cold metering, creating different regional characteristics of hvac development technology. Therefore, in the hvac design will focus on "building energy saving" link.
Hvac energy conservation and environmental protection
Hvac air-conditioning to follow the principle of development, in summary: energy saving, environmental protection, sustainable development, guarantee the health and safety of building environment, to adapt to the national energy structure adjustment strategy, carry out the policy of hot and cold measurement, to create different regional characteristics of hvac development technologies, their specific in 12 aspects can be summarized as the following:
1. The heating technology. The implementation of the household heat metering. The heating system; Low temperature floor radiation heating; The application and development of new type radiator. District heating and cooling, cold and hot electric installations, technology; Distributed cold hot electric installations, technology.
2. Ventilation technology. Hot summer and cold winter region residential ventilation; The infectious disease hospital ward ventilation; Biological clean air conditioning of the air conditioning clean technology such as operating room; Shopping malls, subway and other public space ventilation; Industrial ventilation.
3. The quality of indoor environment. Thermal comfort environment; Indoor air quality (indoor building decoration materials, equipment, emission law research, evaluation method, etc.); Ventilation and air conditioning air distribution and indoor air quality.
4. The gas air conditioning. Gas heat pump; Cold and hot electricity trigeneration using gas; Gas steam combined cycle.
5. Energy storage technology. Ice storage cold air conditioning; Low temperature air supply technology; Water cool storage technology; Regenerative heating.

10. Simulation and analysis technology, intelligent control. Hvac energy consumption simulation and energy analysis; Building automation technology; Hvac and intelligent building.
11. The construction of the installation and operation management. Construction installation technology; Turn over to the authorities and debugging; Operation energy saving; Air conditioning ventilation system cleaning, filter, sterilization, etc.
12. Refrigeration technology. Air conditioning refrigeration technology related research progress; New type refrigeration, natural refrigerants, CFCS refrigerant substitutes; The new refrigeration cycle.
Due to hvac technology development and changes, especially in the construction market competition is intense, the needs of the business is becoming more and more modernization, diversification, attaches importance to the transplantation of foreign technology and the introduction. And the effect of energy saving, environmental protection, green concept and adjustment of energy structure in our country, more and more severe challenges for hvac design, therefore, when in hvac design will focus on "building energy saving" link. Construction of cold, heat and lighting energy consumption reduction is important content of the total building energy consumption were reduced.
