Ushering in a New Era of Green Heating and Hot Water Supply

Against the global backdrop of actively promoting energy conservation, emission reduction, and striving to achieve carbon neutrality goals, the heating and hot water supply sector is in urgent need of innovative green solutions. As a cutting-edge technological product, CO₂ heat pumps, with their unique advantages, are gradually becoming the focus of the industry, providing efficient and environmentally friendly thermal energy services to various fields.

Working Principle: Efficient Cycle Utilizing CO₂ Properties

The operation of CO₂ heat pumps is based on their sophisticated working cycle, which fully utilizes the special properties of CO₂ as a refrigerant. In the system, the compressor first draws in low-temperature, low-pressure gaseous CO₂ and compresses it into a high-temperature, high-pressure supercritical fluid. This supercritical CO₂ then enters the gas cooler, where it transfers a large amount of heat to the flowing water. Through this heat exchange process, the water is heated to the required temperature, up to 90°C for hot water supply or 75°C for heating needs. After releasing heat, the CO₂ is throttled and depressurized through the expansion valve and enters the evaporator. In the evaporator, even at an ambient temperature as low as -35°C, CO₂ can still absorb heat from the outside air or other low-temperature heat sources, re-vaporize into a gaseous state, and then enter the compressor again to start a new cycle. This design utilizes the phase change and heat transfer characteristics of CO₂ under different pressures and temperatures, ensuring that the heat pump can operate stably and efficiently under various complex environmental conditions, achieving continuous heat supply.

Core Advantages: A Perfect Combination of Environmental Protection, Efficiency, and Stability

Excellent Environmental Performance

The CO₂ (R744) refrigerant used in CO₂ heat pumps has unparalleled environmental advantages. Its Ozone Depletion Potential (ODP) is 0, meaning it does not cause any damage to the Earth's ozone layer; its Global Warming Potential (GWP) is only 1, which greatly reduces the risk of greenhouse gas emissions compared to synthetic refrigerants used in traditional heat pumps. At the same time, CO₂ itself is non-toxic and non-flammable, and does not harm the environment or human health. It fully meets the strict requirements of the world today for green and sustainable development, contributing significantly to building an ecologically friendly society.

Excellent High-Temperature Heating Capacity

In terms of heating performance, CO₂ heat pumps are extremely outstanding. They can easily generate hot water up to 90°C. In heating applications, they can achieve a stable water temperature output of 65°C/45°C . This high-temperature hot water supply capacity not only meets the high standards of hot water needs for ordinary residents' daily lives but is also more suitable for scenarios with higher water temperature requirements such as radiator heating. At the same time, in many industrial production processes, it can also provide reliable guarantees for process links that require high-temperature thermal energy.

Strong Low-Temperature Adaptability

Low-temperature environments have always been a challenge for traditional heat pumps, but CO₂ heat pumps can shine in such harsh conditions. It can operate stably at an ambient temperature as low as -35°C, and even at -30°C, its Coefficient of Performance (COP) can still reach 1.8. This characteristic makes it have broad application prospects in severe cold regions such as northern China, ensuring that the interior of buildings remains warm and comfortable during the long and cold winter, and industrial production processes will not be interrupted in heating due to low temperatures.

Wide Applications: A New Green Thermal Energy Choice for Multiple Fields

Civil and Commercial Hot Water Supply

In the hotel industry, a large number of guest rooms require stable and sufficient hot water supply. CO ₂ heat pumps, with their efficient hot water production capacity and stable operating performance, can easily meet the 24-hour uninterrupted hot water demand of hotels, and compared to traditional hot water supply equipment, can significantly reduce energy consumption costs. In school and dormitory settings, the concentrated use of water by students poses a significant challenge to the supply of hot water. The CO ₂ heat pump can intelligently adjust the hot water production according to the water usage pattern, ensuring that sufficient hot water can be provided during peak usage periods to meet the daily needs of students. For example, after the introduction of CO ₂ heat pumps in a university dormitory, 20 tons of 60 ° C hot water were stably supplied daily, meeting the needs of thousands of students, while reducing energy consumption costs by 30% compared to before.
