Thermostatic Radiator Valve is referred to as TRV or temperature control valve. It consists of a valve head and a valve body. Its core component is the sensor unit inside the valve head, commonly known as "temperature bulb". At present, radiator constant temperature control valve has been widely used in urban heating systems in China, it is installed on heating radiators of residential and public buildings, through the temperature control of the room, can not only maximize energy saving, but also provide users with the most comfortable indoor temperature. But do you know the following about temperature control valves?
How does a temperature control valve work?
The temperature bulb is the core of the temperature control valve because it is the "brain" that realizes temperature regulation. The temperature bulb can sense the change of the surrounding ambient temperature and produce a volume change, drive the valve core to produce displacement, and then adjust the amount of water in the radiator to change the heat dissipation of the radiator. The set temperature of the temperature control valve can be artificially adjusted, and the self-acting action is generated by sensing the ambient temperature through the temperature bulb, and the hot water flow flow through the radiator can be adjusted without external power to achieve constant temperature.
What are the types of temperature control valves?
The temperature control valve body is usually manual and automatic. Automatic temperature control valve is composed of self-operated actuator of temperature sensor and special supporting temperature control valve body, automatic temperature control valve is also called constant temperature valve, also referred to as constant temperature valve, temperature control valve body structure is common straight and angular two; Manual temperature control valves usually use a spiral lifting spool, and the rotation of the handle changes from the spiral to the linear displacement of the spool.
The temperature control valve head can be divided into solid, liquid and gas according to the internal filling medium of the temperature sensor, and the appearance of the three media temperature bulbs is not much different, but the performance of the gas temperature bulb is better than the other two energy-saving effects. Danfoss' unique gas bulb technology saves up to 36% of energy, while ordinary liquid bulb saves only about 25%. In addition, Danfoss has introduced electronic temperature bulbs, which use electronic sensors to sense changes in room temperature and realize room temperature control.
What does a temperature control valve do?
The radiator thermostatic control valve is correctly installed in the heating system, and the user can adjust and set the temperature according to the requirements for room temperature. This ensures a constant room temperature in each room, avoiding imbalances in riser water volume and uneven room temperatures between the upper and lower floors of a single pipe system. At the same time, through constant temperature control, free heat, economic operation and other functions, it can not only improve the comfort of indoor thermal environment, but also achieve energy saving.
Constant temperature control
The output is dynamically adjusted with load changes, and the room temperature is controlled constantly, which not only improves the comfort of indoor thermal environment, but also realizes energy saving.
Heat such as sunlight incidence, human activity, cooking, electrical appliances, etc. is called heating free heat, and this part of the heat is not fully considered in the design operation due to uncertainty, and is only considered as a safety factor. After achieving room temperature control, this part of the energy can replace part of the heat dissipation, and at the same time, the temperature difference between the rooms with different orientations can also be eliminated, which not only improves the comfort of the urban thermal environment, but also saves energy.
Office buildings and public buildings do not need to be heated at full capacity at night and on rest days. Residential users also try to make no heat cut off as much as possible to save energy and heat costs. Even different temperature control modes can be implemented in different rooms: when people are concentrated in the living room, the bedroom temperature can be lowered and the living room temperature can be increased; During the sleep break, the bedroom temperature can be increased to the setting, the living room temperature can be lowered to the setting, and so on. These measures can be achieved through the radiator thermostatic control valve, which has achieved the purpose of energy saving.
