Heating reform control valve market to welcome business opportunities

A small valve on the radiator can automatically keep the temperature in the room in winter at the level you think most comfortable; When the outdoor temperature rises on a certain day, the boiler room can also automatically adjust the water temperature, to avoid unnecessary waste of heat; Centrally heated in the same neighborhood between different buildings will not appear some residents too hot to open the window, some room temperature is not enough. The reporter learned from the air conditioning research institute of China building science research institute that these energy-saving technologies and products that have been popularized for more than 30 years in Europe are still very limited in China, and many people still lack understanding of this. In the Ministry of Construction issued recently "the Ministry of Construction on the implementation of heating metering opinions", radiator thermostatic valve, climate compensation, hydraulic balance and other control devices are clearly required to be installed and used in the heating system and buildings.

Radiator thermostatic valve: keep room temperature constant

Radiator thermostatic valve is installed in the front of the radiator of a valve, by the temperature package and valve body two parts. The temperature packet is a temperature control element, which has a temperature sensing medium. When the indoor temperature rises, the medium expands and pushes the valve stem to reduce the opening, thus reducing the hot water supply to the radiator. When the room temperature drops, the medium shrinks, the valve increases the opening degree, and the hot water supply of the radiator increases, so as to keep the room temperature constant, which can not only improve the indoor comfort, but also save energy. Users can also set the temperature according to their own needs, thermostatic valve will automatically control and adjust the hot water supply of the radiator according to the set requirements, so that the room temperature is constant at the level set by users. A large number of European practices show that the use of thermostatic valves can save energy by 30% on average.

Huang Wei, secretary general of the National Technical Committee for Standardization of HVAC and Purification Equipment, told reporters that the first domestic industry standard on radiator thermostatic valves has completed the approval process and will soon be published and implemented. The standard is expected to standardize and promote the thermostatic valve production industry in China.

Climate compensator: dynamic regulation of heat source output

Different from the thermostatic valve installed on each radiator, the climate compensator is installed in the boiler room or heat exchange station, it can make the heat source output according to the outdoor temperature and the heating system back water temperature change dynamic regulation, to achieve heating according to demand. In the city, due to the urban heat island effect, the outdoor temperature is often higher than the weather forecast temperature, if you can not adjust the heat source output according to the indoor and outdoor temperature in real time, it will inevitably cause heat waste. The climate compensator can aim at this point, according to the backwater temperature and outdoor temperature, at any time to control the outlet water temperature, simple and accurate dynamic regulation; Most importantly, it can set the room temperature at different times according to the user's needs. For example, the office building needs room temperature of 18℃ from 8:00 to 18:00 from Monday to Friday, and the antifreeze temperature of 6℃ is only needed in other time periods. The climate compensator will automatically adjust the output level of heating according to the room temperature set value and the outdoor temperature to achieve temperature regulation.
