Embodiment Construction

[0023] The installation sequence of the ceiling radiant cooling (warming) system is as follows:

[0024] 1. Use expansion bolts to fix the wooden square keel on the ceiling at intervals of 30cm, and level it.

[0025] 2. Fasten the prefabricated unit on the wooden keel with special self-tapping nail tube clips. The distance between the pipe staples is about 30cm.

[0026] 3. In the maintenance groove reserved on both sides of the ceiling of the room, connect the connecting pipe fittings with each prefabricated unit, and conduct a hydraulic test.

[0027] The test pressure is the working pressure at the top of the system + 0.2MPa, and the test pressure at the top of the system is not less than 0.4MPa.

[0028] 4. After passing the hydrostatic test, the pressure in the system continues to be in the water-filled state of 0.4MPa. Use cement mortar mixed with 107 glue for construction for the first plastering, and the thickness should be controlled at about 1 / 3 of the total thic...

Abstract

The present invention provides a structural heating ventilation field, providing a ''pre-cast maintainable low-temperature radiation cold supply and heating system, capable of resolving the problem of non-maintenance of the floor heating system once leakage. The system overcomes faults of cockamamie site operation, long days for construction. The system provides ideal end system to comfort heat supplying in winter and cooling in summer to floor source heatpump. The invention creates split pre-cast process and reversed collecting flexibly parallel mounting process, simplifying construction process. The system particular makes convenience to mounting of top cold supplying system, also creating wide market prospect of mass production of the floor heating system. The BMB dampproof insulating process makes dampproof thermal and energy saving effect more excellence. The creative maintenance groove structure conveniently and exactly clears fault, quickly recovers heating supply. Figure 4 is the installation schematic diagram of the floor heating system. 1 is a maintenance groove, 2 is a pre-casting pipe coil, 3 is a flexible pipe coil, 4 is a direct insertion movable joint. 5 is a direct insertion three-way.

Description

Technical field: [0001] The invention relates to the HVAC technical field of low-temperature radiation cooling and radiation heating using the inner surface of a building structure as a cold (heat) radiation surface. [0002] Radiant heating and cooling is hygienic, energy-saving, environmentally friendly, and comfortable, and is conducive to the development and utilization of various energy sources. It can also save indoor area, and can realize many advantages such as "metering by household and temperature adjustment by room". Background technique: [0003] In recent years, the geothermal heating method with energy saving and environmental protection has risen rapidly in our country, and the market prospect is very broad. But so far these heating systems are only used for heating in winter, and the same heating system is rarely used for radiant cooling in summer. In the past, due to the limitation of lack of cold source, this beautiful vision was difficult to realize. ...
