TECHNICAL FIELD

[0001] The utility model relates to the technical field of integrated system, concretely relates to a water temperature control system of radiant air conditioning system. BACKGROUND

[0002] Constant temperature and constant humidity radiant air conditioning system is one of the important technologies for realizing efficient and comfortable environment in modern buildings, which realizes accurate temperature and humidity regulation through radiant pipe system. The development of this kind of system is constantly optimized along with the evolution of building energy saving and environmental control technology. At present, the widely used technical scheme in the market usually includes the combination of mixing valve and proportional integral regulating valve, which realizes accurate control of target water temperature through complex software algorithm calculation. In terms of high precision and flexibility, this kind of scheme has strong adaptability, which meets the temperature and humidity regulation demand in various scenes. However, since the radiant air conditioning system involves the dynamic balance of water temperature and indoor temperature and humidity, its stability and safety are always the core challenges in system design and operation.

[0003] Although the prior art has made certain progress, it still has some deficiencies. On the one hand, under low temperature operating condition, due to the limited waterproof level of system components, damage caused by condensate water is easy to occur, which leads to shortening of component life and decline of system reliability, and it is difficult to fully meet the requirements of users for stability and service life. On the other hand, the current control system usually has a low control range of lower limit of water temperature (usually 5-7℃), and if the system fails, it is easy to cause dewing on the radiant surface, thereby causing irreversible loss to the equipment and building environment. In addition, the existing system relies on the complex algorithm adjustment of electronic equipment, which is greatly affected by software failure or external interference, and it is difficult to provide reliable performance guarantee under extreme conditions. Therefore, how to develop a technical scheme which can improve the water temperature control precision while avoiding the risk of dewing, and significantly improve the stability and applicability of the system, is a problem to be solved at present.
