A heat pump is a high-efficiency energy-saving energy conversion equipment operating based on the thermodynamic reverse cycle principle, serving as a core general thermal energy device in the current green and low-carbon industrial system. Different from traditional boilers and electric heating equipment that directly consume primary energy to generate heat, a heat pump consumes a small amount of high-grade electric energy to collect and upgrade low-grade thermal energy widely existing in air, water bodies, soil and industrial waste heat, converting it into usable high-grade thermal energy and realizing the cross-medium and cross-temperature transfer and reuse of heat energy.
As key energy-saving equipment promoted under the national “Dual Carbon” strategy, heat pumps feature high energy efficiency and power saving, zero clean emissions, dual heating and cooling functions, wide working condition adaptability, stable operation and intelligent controllability. They are widely applied in civil buildings, industrial production, commercial supporting facilities, new energy supporting systems, agriculture and animal husbandry breeding, and public facilities. Acting as a core mainstream equipment to replace traditional coal-fired, gas-fired and oil-fired heating equipment, heat pumps drive energy conservation, carbon reduction, clean heating and waste heat recovery across all industries.
With the comprehensive implementation of green transformation in domestic manufacturing, upgraded building energy efficiency standards, ultra-low emission renovation in industries and clean energy substitution policies, the extensive high-energy-consumption and high-emission heating and cooling modes are gradually phased out of the market. Featuring ultra-high energy utilization efficiency, zero combustion pollution and all-weather stable operation, heat pump technology has become a core approach for new and old energy substitution, industrial waste heat recycling and building energy-saving renovation.
This paper systematically analyzes the technical value, application value and industrial development trends of the heat pump industry from seven dimensions: industrial development pattern, core definition and working principle, core functions, full-scenario industrial application, core equipment selection logic, in-depth technical advantages of Jiangsu Minnuo Group, and future industrial upgrading paths, fully demonstrating the technical iteration and high-quality development of domestic heat pump equipment.
I. Industrial Development Pattern: Carbon Neutrality-Driven Energy-Saving Substitution and Rapid Expansion of Heat Pump Industry
The domestic heat pump industry is currently in a golden cycle of large-scale popularization, technical iteration and accelerated domestic substitution. Guided by national policies such as the Dual Carbon goals, heat pumps are designated as core equipment for energy conservation, carbon reduction, clean heating and waste heat utilization, leading to explosive market demand and two major core development characteristics of the industrial pattern.
On the one hand, clean energy substitution and energy-saving renovation have been fully implemented. Traditional coal-fired boilers, gas-fired boilers and electric heating equipment suffer from high energy consumption, high carbon emissions, high operation and maintenance costs, and heavy environmental compliance pressure, failing to meet the requirements of green production and low-carbon buildings in the new era. Heat pumps realize multiplied energy utilization through heat transfer, with energy efficiency ratio far exceeding that of traditional heating equipment and a comprehensive energy-saving rate of 30%–60%. With no exhaust gas, waste residue or wastewater discharge, they perfectly adapt to energy-saving renovation of industries, clean heating in northern regions and commercial heating and cooling supporting projects, becoming the preferred equipment for energy cost reduction and compliant operation across various industries.
On the other hand, domestic substitution in the field of high-end industrial heat pumps continues to deepen. The market for high-end industrial heat pumps, special working condition heat pumps and high-precision temperature control heat pumps has long been monopolized by foreign brands, which are plagued by high equipment costs, long delivery cycles, slow localized service response, expensive operation and maintenance costs and poor working condition adaptability.
As a leading domestic equipment enterprise, Jiangsu Minnuo Group has been deeply engaged in the field of HVAC compression and thermal energy conversion equipment for many years.

II. Core Definition and Working Principle of Heat Pumps
A heat pump, fully named thermal cycle heat transfer equipment, is a high-efficiency energy conversion device designed based on the second law of thermodynamics and the reverse Carnot cycle principle. Different from traditional heat-generating equipment, it is a typical heat-transfer device. Simply put, a water pump transports water from low altitude to high altitude, while a heat pump upgrades low-grade thermal energy to high-temperature usable thermal energy, realizing the upgrading and reuse of low-grade heat energy driven by a small amount of electric power.
A complete heat pump unit consists of six core modules: evaporator, compressor, condenser, throttling device, intelligent electronic control system and heat exchange pipeline system. During operation, the evaporator absorbs low-temperature waste heat from air, water bodies, soil or industrial waste gas and wastewater. The compressor works to compress and raise the temperature of the refrigerant, converting low-grade thermal energy into high-grade thermal energy. The condenser then releases heat to realize heating, hot water supply, drying and process heating functions. In cooling mode, the system operates in reverse to achieve ambient cooling, realizing dual functions of heating and cooling with one single device.
Compared with traditional heating equipment, heat pumps require no fuel combustion, produce no open flame or emissions, and have no explosion risks, with far higher energy utilization efficiency. Their COP (Coefficient of Performance) reaches 3.0–6.0, meaning consuming 1 kWh of electricity can transfer 3–6 times the thermal energy of electric power, delivering prominent energy-saving and green environmental advantages.
According to heat sources, heat pumps are divided into four mainstream categories: air-source heat pumps, water-source heat pumps, ground-source heat pumps and industrial waste heat heat pumps, adapting to the temperature, humidity, environmental and energy consumption requirements of different scenarios.
III. Core Functions and Industrial Roles of Heat Pumps
As a highly versatile thermal energy equipment, heat pumps are no longer limited to traditional civil heating scenarios, but are deeply applied in core fields such as industrial production, urban supporting facilities, new energy industries and environmental governance.
