Both air-cooled heat pump units and air source heat pump units are heat pump systems that can convert low-temperature heat energy in the environment into high-temperature heat energy, achieving heating or cooling. Although they all use air as a heat source, their working principles, application scenarios, and advantages are different.

Working principle: There are differences in the working principles between air-cooled heat pump units and air source heat pump units.

The air-cooled heat pump unit adopts an air-cooled refrigeration cycle system. The compressor compresses and heats up the low-temperature and low-pressure refrigerant to reach a high-temperature and high-pressure state. Then, the condenser releases heat from the high-temperature and high-pressure refrigerant, turning it into a high-temperature and high-pressure liquid. The expansion valve reduces its pressure and turns it into a low-temperature and low-pressure liquid. Then, the evaporator absorbs the low-temperature heat energy in the air, Turn the low-temperature and low-pressure refrigerant into a low-temperature and low-pressure gas state to complete the cycle.

The air source heat pump unit adopts an air source heat pump cycle system, which absorbs low-temperature heat energy from the air through the evaporator, causing the refrigerant to become a low-temperature and low-pressure gas state. Then, the compressor compresses and heats the refrigerant to reach a high-temperature and high-pressure state. Then, the condenser releases heat from the high-temperature and high-pressure refrigerant, making it a high-temperature and high-pressure liquid state. The expansion valve reduces its pressure, Transforming into a low-temperature and low-pressure liquid, and then absorbing low-temperature heat energy from the air through the evaporator, the low-temperature and low-pressure refrigerant is transformed into a low-temperature and low-pressure gaseous state, completing the cycle.

Application scenario: Air cooled heat pump units are mainly used in air conditioning, cooling water, and heating systems, suitable for environments with relatively low temperature requirements, and typically used in small commercial and residential buildings. Air source heat pump units are widely used in fields such as homes, commerce, industry, and public buildings, both for heating and cooling. They are suitable for temperature conditions in most regions, especially in moderate temperature climates, and their performance is even better.

Both air-cooled heat pump units and air source heat pump units have their own advantages.

The advantages of air-cooled heat pump units include:

Easy installation, no need for civil engineering, saving installation costs and time costs.

Energy conservation and environmental protection, capable of recycling and utilizing waste heat, reducing energy consumption and pollution emissions.

Stable operation, long service life, and relatively low maintenance costs.

The advantages of air source heat pump units include:

It has a wide range of applications and can adapt to most climatic conditions and temperature requirements.

Capable of simultaneously completing heating and cooling functions, with high comprehensive performance.

Stable operation, long service life, and relatively low maintenance costs.

In summary, there are differences between air-cooled heat pump units and air source heat pump units in terms of working principles, application scenarios, advantages and disadvantages. When choosing which type of heat pump unit to use, it is necessary to comprehensively consider the actual situation and choose a heat pump unit that is suitable for one's own needs.
