A small valve on the radiator, you can make the winter the temperature of the room is always automatically maintained at you think the most comfortable level; When a day of outdoor temperatures, the boiler room can also automatically adjust the water temperature, to avoid unnecessary thermal waste; central heating in the same cell between the different floor, and some households will not be hot windows, and some room temperature would not be enough. The reporter learned from China Academy of Building Research Institute learned that the air-conditioning, which has been popular in Europe than 30 years of energy-saving technologies and products, the current application in China is also very limited, many of whom are still lack of understanding. In the Ministry of Construction recently issued a "Ministry of Construction on the implementation of measures to promote the views of heating", the radiator thermostatic valve, climate compensation, water balance, regulation and control devices are clearly required heating systems and buildings to be installed to use.
Thermostatic radiator valves: to maintain a constant temperature
Thermostatic radiator valve is installed in front of a radiator valve, from packages and body temperature of two parts. Winn package is the temperature control components, which felt warm medium, when the indoor temperature rises, media expansion, promoting stem reduced aperture, thereby reducing the radiator hot water supply; room temperature falls, the media shrink, increasing the valve opening, radiator hot water supply increased, thereby maintaining a constant temperature, so that not only can improve indoor comfort and energy efficiency. Users can also set according to need its own temperature, the thermostatic valve will be required to set automatic control and regulation of the supply of hot water radiator, so that the user to set at room temperature a constant level. A large number of European practice shows that the use of Thermostatic Valve average energy savings of 30%.
National HVAC air-conditioning and Purification Equipment Standardization Technical Committee Secretary-General Huang told reporters that Guoneishoubu radiator thermostatic valve on the industry standard for the approval process has been completed, and soon will announce the implementation of the standard is expected to regulate and promote the production of our country's Thermostatic Valve industry.
Climate Compensator: dynamically adjust heat to contribute to
With the thermostatic valve installed on each radiator in different climate compensator is mounted in the boiler room or a heat transfer station, it can contribute to heat under the outdoor temperature and the heating system return water temperature changes in dynamic adjustment to achieve heating according to demand . Cities, as urban heat islands, outdoor temperature is often higher than the temperature of weather, if not immediately adjust their heat source under室内外温度contribute, will inevitably result in a waste heat. Climate compensator is to address this point, according to the backwater temperature and outdoor temperature, time control of water temperature, simple, accurate dynamic adjustment; most important thing is, it can according to user need to set different time periods at room temperature. For example, for offices, Mondays through Fridays 8:00 to 6:00 p.m. need to room temperature 18 ℃, the other time just freezing temperature of 6 ℃, weather compensator at room temperature setpoint will automatically adjust the heating and the outdoor temperature contribute to standards, and achieve temperature regulation.
Li Xiaopeng of China Ministry of Danfoss introduced the residential heating, climate compensate for energy-saving effect is very prominent, and investment recovery period is typically less than a year. Currently, Beijing heating season the average consumption of 11 to 15 cubic meters per square meter of natural gas, and if compensation technique using the climate system, most can be consumed per square meter to achieve 7 to 8 cubic meters of gas. It is reported that in 2002, the National Defense University Flower 2 million for climate compensation for technical transformation, when natural gas fuel saved 1.2 million yuan.
Hydraulic Valves: regulating water flow balance
With a plot that some users would often fail to reflect the temperature heating standards, while some users are due to room temperature is too high, had to open the window cooling, which is to bring users the most intuitive hydraulic imbalance feelings.
Hydraulic balancing valve is a front of the installation of measuring flow control valve, hydraulic imbalance in our country a very serious situation, the balance valve has a great energy-saving effect and popularization. As the building heating system, there are theoretical design and actual construction of the gap, the result is a system of hydraulic imbalance, thereby affecting the quality of some end-users of the heating. A hydraulic system be connected to each other network, in the heat out of the total volume remains unchanged, a number of user terminals of the heating temperature exceeds the heating standards will affect the other user terminals of the water flow, thereby affecting the supply of these users thermal mass. Hydraulic Valves that regulate water flow can be a device in order to achieve a balanced flow of hydraulic systems. The floor, large water flow, and on the off small point, that floor, flow rate, and on the open big points so that the floor of the flow balance. Ding Jian China Office Kamulupu company introduced water balance valve is a very economical energy-saving products and investments were less than 0.5 yuan per square meter, but it brings 15% of the energy-saving effect but people can not be belittled.
