Embodiment Construction
[0034] The present invention will now be described with reference to the accompanying drawings. refer to figure 1 , the HVAC terminal integrated pipeline system of the present invention includes a multi-pipeline pressure balance filter device 1 and a plurality of fan coil units 2, and the water outlet and water inlet of the multi-pipeline pressure balance filter device 1 pass through flexible pipes 3 and multiple The water inlet and water outlet of each fan coil unit 2 are directly connected to form a plurality of water supply and return loops a...f. Wherein, the outside of the flexible pipe 3 is wrapped with thermal insulation cotton, and the flexible pipe 3 is preferably a PEX pipe, optionally a PERT pipe, a PE pipe or other soft pipes. As a result, PEX pipes with self-insulation are formed. PEX pipes with self-insulation are adopted. Due to the advantages of PEX pipes, they have good low-temperature toughness and good stress crack resistance. The inner wall roughness of th...

The invention provides an integrated pipeline system at the tail end of heating, ventilation and air conditioning. The integrated pipeline system at the tail end of heating, ventilation and air conditioning comprises multiple pipeline pressure balancing filtering devices and multiple blower coils. The integrated pipeline system at the tail end of heating, ventilation and air conditioning is characterized in that water outlets and water inlets of the pipeline pressure balancing filtering devices are directly communicated with water inlets and water outlets of the blower coils through soft pipelines respectively, and multiple backwater supply circuits are formed, so that the installing procedures are simplified, and partial resistance of the pipeline system is reduced.
Description
technical field [0001] The invention relates to the field of installation of central air-conditioning and hot water supply system terminal pipelines, and more specifically relates to a HVAC terminal integrated pipeline system. Background technique [0002] According to the design plan of the design institute for the existing central air-conditioning and heating systems, the fan coils of the water system are all made of steel pipes from the main pipe to the branch pipes. [0003] When the pipeline adopts galvanized steel pipe, the connection method of the steel pipe is threaded connection. Zinc direct, galvanized elbow, galvanized tee, etc.) for connection. This kind of system has high requirements on the quality of the installers, who need to be proficient in sheet metal, welding, painting, heat preservation, and debugging, and the construction personnel need to be familiar with the drawings. Only by understanding the design concept and having many times of construction ex...
