As an end - of - line heat exchange equipment in central air - conditioning systems, fan coil units (FCUs) are widely used in various civil and commercial buildings such as office buildings, hotels, hospitals, residences and shopping malls, relying on their advantages of compact structure, low energy consumption and flexible adjustment. They are one of the core equipment to achieve precise control of indoor temperature and ensure a comfortable environment. This article will systematically explain the product knowledge of fan coil units, including working principles, core structures, classification methods and key technical points. Combined with industry application scenarios and GTGLOBE product advantages, it will comprehensively present the product characteristics and application value of fan coil units.

Entering 2026, the global HVAC industry is at a critical juncture intertwined with multiple changes — the continuous upgrading of the EU F-GAS Regulation is driving refrigerant iteration, the deepening of China's "dual carbon" policy is forcing the upgrading of energy-saving technologies, while market involution intensifies and channel competition becomes increasingly fierce, and terminal demand is accelerating its transformation from "single product procurement" to "integrated solutions". Against this backdrop, enterprises with a full industrial chain layout and improved product matrix have become the core force to resist industry fluctuations and seize market opportunities. GTGLOBE has been deeply engaged in the HVAC field for more than 20 years, with products covering over 60 countries worldwide. With a full-series product layout of "heat pumps + fan coil units + pump sets + manifolds + floor heating pipes", it accurately conforms to the industry development trend, providing one-stop HVAC solutions for global distributors, contractors and terminal customers, and demonstrating unique advantages in the industry changes.

Driven by the global "dual carbon" goals and EU environmental regulations, R290 (propane) has become the core technical path in Europe's refrigerant replacement process, thanks to its extreme environmental protection properties (GWP of only 0.02, based on AR6 standards) and high energy efficiency advantages. Particularly noteworthy is that the new EU F-GAS Regulation has clearly defined a phase-out timetable for HFC refrigerants. As a widely used transitional refrigerant in the current heat pump field, R32 will soon be prohibited from being used in new products. This policy orientation will reshape the European heat pump industry pattern from multiple dimensions including policy, market, and technology, further accelerating the market penetration of R290. Based on market research data from multiple regions in Europe and industry practices, the GTGLOBE brand has accumulated a large-scale customer base in the European R290 heat pump market with its precise localized adaptation and stable product performance, and its customer coverage and market penetration are showing a steady growth trend. Its market development path not only has important reference value for industry development, but also conforms to the industry transformation needs under the background of R32 phase-out.

Against the backdrop of the EU's "dual carbon" goals and the continuous upgrading of environmental regulations, R32 heat pumps in Europe are in a "transitional decline period". Their market position, service life, and post-maintenance are all subject to clear policy constraints and market trend impacts. As a brand that simultaneously deploys both R32 and R290 dual-refrigerant heat pumps, GTGLOBE has formed a differentiated competitive advantage during the industry transformation period through its precise European market layout and technological innovation. In particular, the photovoltaic direct-drive technology of its R32 heat pumps has further enhanced its competitiveness in the stock market.

As a core piece of equipment in the global energy-saving and low-carbon transformation, heat pumps have attracted widespread attention and been widely applied in the HVAC industry due to their efficient energy utilization characteristics. Entering 2026, against the backdrop of the continuous implementation of global environmental protection policies, accelerated refrigerant iteration, and in-depth advancement of the "dual carbon" goal, heat pumps have become a key force driving the high-quality development of the HVAC industry. This article will systematically interpret heat pump product knowledge, including their working principles, core classifications, and key technical points, and combine GTGLOBE's development layout to analyze the practical application value and future development trends of heat pumps in the global market.

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.
