With the global HVAC industry accelerating its transformation towards energy conservation, environmental protection and high efficiency, heat pump systems, as the core equipment for energy-saving heating, have been widely applied in various scenarios such as residential, commercial and industrial fields (this article focuses on the application in heat pump floor heating systems). As a key supporting component in the hydraulic circulation system of heat pump units, the manifold directly determines the stability, operating efficiency and service life of the entire heat pump system. Among them, the GTGLOBE 1 1/4” inlet and return water stainless steel manifold, with its precise caliber design, excellent material performance and perfect adaptability, has become the preferred supporting component for GTGLOBE heat pump systems and many similar heat pump systems. It effectively solves the pain points existing in the application of traditional manifolds, such as uneven water distribution, poor corrosion resistance and low system efficiency, and has become a core link to improve the comprehensive performance of heat pump systems, demonstrating GTGLOBE's R&D strength in the field of HVAC supporting components.

As a professional HVAC manufacturer with 22 years of technical accumulation, GTGLOBE has always focused on the R&D and production of high-quality supporting components for heat pump systems. The independently developed 1 1/4” (32mm) inlet and return water stainless steel manifold is tailor-made for heat pump floor heating systems. It integrates the advantages of reasonable caliber adaptation, superior material performance and convenient installation. It can be closely matched with the full range of GTGLOBE heat pump products without additional adaptation and commissioning, building a stable and efficient hydraulic circulation system for users and further improving the product matrix of GTGLOBE heat pump floor heating systems.

Core Design: 1 1/4” Caliber, Precisely Matching the Needs of Heat Pump Systems

The 1 1/4” (DN32) inlet and return water caliber is not randomly set, but scientifically designed by GTGLOBE based on in-depth research on the hydraulic characteristics of heat pump floor heating systems and combined with the actual operating parameters of its own full-specification heat pump units (6KW to 260KW). It can perfectly match the water flow needs of GTGLOBE heat pump systems and similar mainstream heat pump systems, achieve precise balance of water supply and return, and lay a foundation for the efficient operation of the system.

Compared with the traditional 1” (25mm) caliber manifold, the GTGLOBE 1 1/4” stainless steel manifold has a larger flow area. Its designed flow rate is 7L, which is much higher than the 5L of standard products. It can reduce the water flow resistance in the pipeline by 20%-30%, effectively avoiding the problem of insufficient water supply caused by small caliber and insufficient flow in high-power heat pump systems. It ensures that the heat exchange medium (water) circulates efficiently between the heat pump unit and the floor heating pipes, gives full play to the heat exchange efficiency of the heat pump unit, and further reduces energy loss. At the same time, the precise caliber design can realize uniform distribution of water flow in each branch, avoiding uneven heat exchange and abnormal operation of floor heating pipes caused by excessive or insufficient water flow in local branches, and comprehensively ensuring the stable and efficient operation of the entire heat pump floor heating system.

Material Advantages: Stainless Steel, Building a Durable Foundation for Heat Pump Systems

The GTGLOBE 1 1/4” inlet and return water stainless steel manifold is made of 304 food-grade stainless steel, processed by GTGLOBE's precision forging technology and special anti-corrosion treatment. Compared with traditional copper and plastic manifolds, it has irreplaceable material advantages, perfectly adapts to the long-term operating environment of heat pump floor heating systems, and is highly consistent with the high-quality positioning of GTGLOBE heat pump units.

On the one hand, stainless steel has extremely strong corrosion resistance and anti-aging performance, which can effectively resist corrosion caused by water impurities and heat exchange medium residues in the heat pump system, avoid scaling and rusting on the inner wall of the GTGLOBE manifold, and extend its service life to more than 15 years, far exceeding that of traditional plastic manifolds (5-8 years) and ordinary copper manifolds (8-10 years), greatly reducing the user's later replacement and maintenance costs. On the other hand, stainless steel has stable thermal conductivity, and will not experience material deformation, brittle fracture and other problems due to temperature changes during the operation of the heat pump system (the water temperature range is usually 5℃-55℃). It can perfectly adapt to the winter low-temperature heating operating conditions of the heat pump system (adapting to the needs of floor heating), ensure the tightness and stability of the hydraulic circulation system, and eliminate the hidden dangers of water leakage and seepage from the source. In addition, 304 stainless steel is environmentally friendly and non-toxic, without the release of any harmful substances. It not only conforms to the "dual carbon" policy and the demand for environmentally friendly heating, but also can be adapted to scenarios with high requirements for water quality and environmental protection such as residences, hospitals and schools, taking into account both practicality and environmental protection.
