Supply and return water temperature by 3.1.1 low temperature hot water floor radiant heating system is calculated, the water temperature should not exceed 60 DEG C. The water temperature of civil buildings is 35 to 50 DEG C, the temperature difference between supply and return is not greater than 10 DEG C. The calculated value should be consistent with the provisions of table 3.1.2 the average surface temperature of 3.1.2. Table 3.1.2 the average surface temperature (c) regional characteristics of people often stay in personnel short stay residence area 35 ~ 404228 unmanned area range from 24 to 26 to 3032 for the highest limit of 28 3.1.3 low temperature hot water floor radiant heating system working pressure should be less than 0.8MPa; when the building height of more than 50m, should set the vertical partition. 3.1.4 regardless of the heat, pressure and other parameters with low temperature hot water floor radiant heating medium temperature, flow rate and capital should be matched with the heating system; heating system should be set up corresponding control device. The content and depth of 3.1.5 ground radiation heating engineering construction drawings and design documents, shall meet the following requirements: 1 construction drawings and design documents should be based on the construction drawings, including drawings, catalog design specifications, heating pipes or heating cable layout, temperature control device layout and water separator, a water collector, ground structure diagram etc.. Two Design specification shall describe the calculation of temperature, indoor and outdoor heating heat source and heat medium parameters, distribution scheme and power load, heating pipes or heating cable specifications and technical data; identify the specific
