Abstract: Since the reform and opening up, with the rapid development of China's construction, the new high-rise buildings to gradually increase. To not be optimistic about our current forms of energy, reduce building energy consumption is to implement the scientific concept of development sustainable development of major strategic initiatives. To of a residential building in Harbin, respectively, using a continuous heating and intermittent heating in two different ways of heating a comparative study of human comfort and Environmental Protection from both revealed the superiority of continuous heating.

1 Status of heating
After the reforms, the rapid development of China's construction, in particular the reform of housing system in recent years has greatly promoted the development of domestic industry and national economy. At present each child 17-18 million square meters of new housing. With lots of new construction, building energy consumption of a building using the energy consumption, including heating, air conditioning, hot water, cooking, household appliances and other aspects of energy consumption, including heating, adjusting energy consumption accounts for 60% -70%. according to the 1998 estimated data, the Chinese construction energy consumption of commodities in goods accounted for 27.6% of total energy consumption, close to 30% -40% in developed countries. China's energy situation is serious. China's coal, oil, gas, water resources per capita is about the world average of 1 / 2, 1 / 9, 1/23.1/4. 1t per capita energy consumption for the standard coal, the world's per capita energy consumption is only less than half of 2.4t of standard coal, thereby reducing the buildings energy consumption can be achieved sustainable development, is to save energy path. in fact change the traditional way of heating energy saving way out. as the office building, auditorium, laboratory and teaching buildings, student dormitories, heating demand is not the same, no 24h constant temperature heating, the system should be used intermittently in order to achieve harmony with the heat and heating. For in the larger central heating systems, but also sharing the building can be sub-heating method, because the buildings do not have the same time to heating, heat scale and operating load greatly reduced, thereby reducing heat investment and long-term goal to achieve on-demand heating.

2 new environmentally friendly energy saving heating heating system
Heating heating methods are many different ways, hot water, electric, geothermal, and so in different ways, in recent years a new type of environmentally friendly energy saving heating heating system, recently passed the China Energy Research Organization experts. Experts that the system for domestic initiative, the international advanced level. This changed the traditional heating system heating heating methods, it is not with the heat transfer medium of water, but by the complex chemical media '`ZGM''for the heat conduction Gong quality, to break the traditional water as the working fluid heat transfer model. This complex chemical media "ZGM''non-toxic, tasteless, non-corrosive, non-volatile, not burning, plumbing, does not scale. the use of the heating medium system, long back fast, uniform temperature, good thermal stability, and structural appearance, flexible installation, to solve the domestic existing single-tube system can not solve the problem. The system can save 40% -50% of energy. because they do not water, they are able to greatly reduce water consumption. The system consists of high-tech development Co., Ltd. Beijing New World to manufacture, is the best way of heating in winter, appropriate institutions, agencies winter heating use.

Three institutions, authority to use the winter heating
Institutions, agencies with multiple types of buildings, multi-purpose features. Include: office buildings, teaching buildings, student dormitories, faculty family wings, laboratories, auditorium, gymnasium, school-run factories. Institutions heating has two characteristics : First, for intermittent heating, various types of buildings is not the same heating time, the auditorium and gymnasium, its use of time are extremely rare, heating duty can be set at other times, so it's heating Intermittent strong: for student dormitory, during school hours (including night classes) may set the duty heating, while the early, middle and late time to ensure the heating breaks: For the office building, the heating duty can be set working hours , time to go to work to ensure that heating; and for laboratories, faculty family wings, etc., in the heating time should be controlled according to specific circumstances. Second, there is another feature of the school winter vacation. In the winter period (35 days) the institutions most of the buildings can only guarantee duty heating. Based on the above characteristics, the ways and means for heating, heating energy savings institutions will be very significant. reposted elsewhere in the Research Papers Download http://www . hi138.com 4 Comparison of human comfort
The traditional way of using a continuous heating, when the outdoor temperature is -2690, heat medium parameter is 95/70 ��, the heat dispersion without interruption to the space to complement the external structure of the heat loss, physical fitness indoor temperature fluctuations in the range of design parameters inside. When the outdoor temperature is higher than 26 ��, thermal coal, used to change parameters of a qualitative approach to mediation, the system is still continuous operation, you can guarantee the stability of the indoor design temperature to meet the requirements of the human body comfort. intermittent heating is non-combustible a day at room temperature a larger range within 24h, if the heating time to ensure that the room temperature will be lower than the interval of time at room temperature design temperature. Conversely, if the interval of time to ensure that the design temperature of the heating time and indoor temperature be higher than the design temperature. intermittent heating temperature difference a day when about 10 ��, indoor temperature fluctuated, the body feels hot and cold, susceptible to cold. But if the use of new environmentally friendly energy saving heating system can heat change this situation, the new environmentally friendly energy saving heating heating system is change the status quo, the new environmentally friendly energy saving heating heating system heating up fast, long holding time, at a temperature under a temperature of 20 ��, 45min to room temperature, including can reach 18 ��.

5 Comparison of Environmental Protection
In China, Environmental Protection more and more aroused great attention. Now our country is to promote Environmental Protection. When the continuous heating, due to the uninterrupted operation of the boiler, furnace and always maintain high temperatures in coal combustion of the volatile combustible gases, reducing The chemical furnace incomplete combustion losses, reducing the boiler exhaust. intermittent pressure fire heating 2-3 times a day, each time the fire when the pressure increased as a vote of coal, the furnace blower to stop the gas, the furnace temperature decreased rapidly, incomplete combustion chamber loss of the chemical was increased, the furnace did not reach the ignition of flammable gases the phenomenon of black smoke appeared in serious pollution of the atmospheric environment, but new environmentally friendly non-polluting energy-saving heating system heating run.

Conclusion
Some can be concluded from the above, continuous heating and intermittent heating compared to their own merits. Generally is not used intermittent heating. But if we adopt the new environmentally friendly energy saving heating system, it will show intermittent heating big advantage, therefore, the human body from the comfort of energy saving point of view, we should vigorously promote the adoption of Environmental Protection of intermittent heating with new energy-saving heating heating system.
