What is a dual-source heat pump?

What is a dual-source heat pump?
A dual-source heat pump refers to a heat pump system that utilizes two different heat sources (such as air and soil, air and water bodies, etc.). 

The system can automatically select the most suitable heat source based on external environmental temperature, load requirements, etc., 

or achieve coordinated operation of multiple heat sources, thereby improving the overall operational efficiency.

Compared with single-source heat pumps, dual-source heat pumps have more obvious advantages in extreme climate conditions. 

For example, in winter environments with low temperatures, they can avoid the problem of air source efficiency decline, ensuring the stability of heating; 

during transitional seasons, they prioritize the use of air heat sources, reducing operating costs. 

1. Application fields:

(1) Central air conditioning industry

1.Comfortable central air conditioning: It must be used in various engineering buildings for cooling and heating, 

such as business hotels, hotel restaurants, office buildings, hospitals, schools, residential communities, shopping malls, complexes, logistics parks, industrial park factories, and production workshops.

2. Air purification: For areas that require constant temperature and humidity control, such as hospitals and clean workshops.

3. Processing technology for central air conditioning: The processing technology of the factory involves temperature reduction and cooling.

(2)Heating, Environmental Sanitation and Hot Water Industry

1.Large-scale centralized heating, residential communities, hospitals, educational institutions, office buildings, hotels and guesthouses, single-family villas, rural houses, factory workshops.

2. Production process flow: Heating and hot water, such as electric heating for pipeline transportation, heating of oil, heating of acid washing, passivation, 

and electroplating tanks, heating of various necessary hot water and clean production workshops, and bathrooms.

(3) Crop cultivation, livestock rearing and drying processing industry

1.Heating (cooling) equipment for greenhouse facilities for potted flowers, vegetables and fruits, and fresh fruit cultivation, with constant temperature and humidity.

2. Various equipment for cultivating fungi with constant temperature and humidity, and control of carbon dioxide content.

3. The chicken, duck, goose and pig pens maintain a suitable temperature through natural ventilation.

4. Heating and temperature control are applied to the water surface in marine aquaculture.

5. Various agricultural and sideline products, industrial supplies, and materials such as sludge that require drying treatment.

(4) Refrigerated Cabinet Cold Chain Transportation Industry

Various types of air conditioning systems for high-temperature rapid freezing cold storage facilities and cold chain transportation offices in commercial buildings.
(5)Environmental protection and energy conservation industry renovation and upgrading, energy contract management

1.Energy-saving buildings, various engineering buildings' energy-saving projects for cooling, heating, environmental sanitation and hot water supply.

2. Industrial environmental protection: For companies that have waste heat recovery systems in operations, 

such as those in mining, oil and gas fields, power plants, steel mills, smelters, chemical plants, paper industries, dyeing and printing industries, and data centers, 

we will provide the most optimal control power energy conservation solutions and machinery equipment.

3. Investments in energy conservation and environmental protection projects with a duration of no more than three years, 

or in supply and heating projects for public buildings, hospitals, and educational institutions with a duration of no more than four years, 

for investment and operation management purposes.
