Plumbing is one of the radiant floor heating, and it is also the most popular heating method. It is quite advantageous compared to electric heating. Plumbing is through the ground coil, there is circulating hot water in the pipe, through the heat medium in the floor radiant layer, the entire ground is evenly heated, and the ground's own heat storage and heat radiation are conducted from bottom to top. heating purpose. Since the temperature gradient gradually decreases from the sole of the foot to the head is formed indoors, it gives people a comfortable feeling of warm feet and cool head. Floor radiant heating conforms to the fitness theory of "warm feet and cool tops" in traditional Chinese medicine. It is the most comfortable heating method and a symbol of modern life quality. 1. Water floor heating is the overall heating of the ground, the heating is uniform, and the comfort is better; 2. The heat dissipation of the radiator terminal drives the room temperature, the indoor temperature is uneven, and the comfort is worse; 3. The water and floor are warm and the ground is hot, which is warm enough and cool at the top, which is more suitable for Chinese medicine health care. 4. Water floor heating takes up more floor height. Water floor heating ground structure: thermal insulation layer, heating layer, heat storage layer. The thermal insulation layer is often referred to as the thermal insulation board, the heating layer is the heating pipe, and the thermal storage layer is the cement layer. Aside from the floor or floor tile height, the floor heating part occupies a floor height of about 5.5 cm. 5. The radiator water supply pipes are generally buried under the ground. However, the pipes are directly buried in the concrete and do not directly occupy the floor height. 6. The radiator heats up faster. When the water floor heating starts to heat, it is necessary to first heat the cement layer above the hot water pipe, then heat the floor, and then the floor heats the air. It takes a long time from opening to reaching the expected temperature; while the radiator terminal dissipates heat, the cement layer does not need to be heated. And the floor, the indoor temperature rises faster for the first time. (Therefore, the use of water floor heating and radiators is very different. Generally, water floor heating is not completely closed. When no one is at home, it is also in operation and not completely closed.) Water tank, water pump, water meter, solar water heater , return blockers, filters, water purifiers, boilers, hardware materials, radiators, plumbing fittings, sanitary ware Water heating boilers, thermostats. 1. The construction of the floor radiant heating system should avoid cross-construction operations with other types of work, resulting in difficulties in coordination or unclear responsibilities, delaying the construction period, and difficult to guarantee the quality. Users need to let us communicate with the decoration company in advance to coordinate the work cooperation process; 2. The water and electricity transformation should be completed before the construction of the floor heating system. Before installing the floor heating system, it should be ensured that the construction of the water and electricity pipelines at the construction site is completed, the closed water test of the kitchen and toilet should be completed and accepted, and the ground in the construction area is flat and clean, and there are no exposed steel bars, water and electricity pipelines and any equipment that affects the construction. materials, sundries, etc.; 3. Looking for a decoration company to do the backfilling of bean stone concrete is the same as asking us to do it. We recommend that the decoration company do this project, and the decoration company does the backfilling. It can also be paid attention to to minimize the possibility of damage to the floor heating during construction; 4. The owner should assist us in coordinating the relationship with the property company and neighbors to create conditions for the normal construction, including handling the corresponding personnel and equipment pass, start-up and acceptance approval procedures at the property and other relevant departments. Construction attention 1. The construction of the concrete filling layer shall be completed within 48 hours after the installation of the floor heating heating pipe and the qualified hydraulic test; 2. The construction of the concrete filling layer should be undertaken by a qualified civil construction party, and our unit will cooperate closely; 3. During the construction of the concrete filling layer, the water pressure in the heating pipe should not be lower than 0.6MPa, and during the curing process of the filling layer, the system water pressure should not be lower than 0.4MPa; 4. The filling layer is a structural layer used to protect the plastic pipe and make the ground temperature uniform. It is generally bean stone concrete, the particle size of the stone should not be greater than 10mm, the volume ratio of cement mortar should not be less than 1:3, and the concrete strength grade should not be less than C15. The thickness of the filling layer should meet the design requirements, and the flatness should not be greater than 3mm; 5. The floor heating system needs to lay expansion joints at the vertical junctions of walls, columns, doors, etc. with the ground. The width of the expansion joints should not be less than 10mm. When the ground area exceeds 30 square meters or the side length exceeds 6m, expansion joints and expansion joints should be installed. The width should not be less than 8mm; the above expansion joints have been laid before the construction of the concrete filling layer, and attention should be paid to protect the expansion joints from being damaged during the construction of the concrete filling layer; 6. During the construction of the concrete filling layer, it is strictly forbidden to use mechanical vibrating equipment; construction personnel should wear soft-soled shoes and use flat-headed shovels. Debug Note 1. The low-temperature hot water ground radiant heating system is strictly prohibited to operate without debugging. 2. The commissioning and operation of the low-temperature hot water ground radiant heating system should be carried out under the conditions of normal heating and power supply. 3. The initial heating (operation and debugging) must be carried out after the curing cycle of the concrete filling layer is completed and the filling layer is completely dry naturally. 4. The commissioning of the low-temperature hot water ground radiant heating system should be carried out by the construction unit with the cooperation of the construction unit. 5. When heating for the first time, the temperature of the hot water should be gentle, and the temperature of the water supply should be controlled at about 10?C higher than the ambient temperature at that time, and should not be higher than 32?C. At this water temperature, it should run continuously for 48 hours; after that, the water temperature will increase by 3?C every 24 hours until it reaches the design water supply temperature. At this temperature, each component and the heating pipe connected to the water collector should be adjusted one by one until it runs normally. 6. The heating effect of the low-temperature hot water ground radiant heating system should be based on the temperature indicated by the black ball thermometer at the center of the room 1.5m above the ground as the basis for evaluation and assessment.
