1. The working principle of air energy floor heating heat pump system

The air energy floor heating heat pump system extracts low-grade heat energy from outdoor air through the principle of "reverse Carnot cycle", which is converted into high-grade heat energy for heating after the compressor works. The work process can be divided into four key stages:

1. Evaporative endothermic: The refrigerant absorbs heat from the air in the evaporator

2. Compression and heating: The compressor compresses low-temperature and low-pressure gases into high-temperature and high-pressure gases

3. Condensation and heat release: High-temperature refrigerants release heat in floor heating pipes

4. Throttle and pressure reduction: The expansion valve reduces the refrigerant pressure and completes the cycle

2. The five core advantages of air energy floor heating

 1. Excellent energy-saving and environmental performance

• Energy efficiency ratio (COP) up to 3.5-4.0

• Compared with traditional electric heating, it saves more than 60% energy

• Zero carbon emissions, no combustion pollution

• Comply with national green building standards

2. Unparalleled comfort

• Radiant heating on the ground, evenly distributed temperature

• The room temperature gradient conforms to the ergonomics of "warm feet and cool head"

• No wind, no noise, no drying

• Maintain indoor humidity in the optimal range of 40-60%

3. Flexible space utilization

• The main unit only needs 1-2 square meters of installation space

• No indoor unit required, no wall occupancy

• Concealed installation, does not affect the decoration style

• It can be perfectly combined with solar energy systems

4. Intelligent control system

• Mobile APP remote control

• Divided rooms with time-sharing temperature control

• Automatically memorize user habits

• Real-time monitoring and analysis of energy consumption

5. Long service life

• The design life of the main unit is 15-20 years

• The life of floor heating pipes is more than 50 years

• Simple maintenance and low failure rate

• The long-term cost advantage is obvious

 3. Four usage restrictions that need to be considered

1. The initial investment is high

• The equipment + installation cost is about 300-500 yuan/㎡

• higher than gas wall-hung furnace

•  It takes 5-7 years to recover the cost difference

2. Environmental adaptability limitations

• The efficiency below -25°C decreases significantly

• The northern region needs to be equipped with auxiliary heat sources

• Frost may form when the humidity > 85%

3. Strict installation requirements

• Professional design of hydraulic systems is required

• The building insulation requirements are high

• Power configuration needs to meet demand

 4. Operational precautions

• Avoid frequent start-ups and downs

• Freeze protection is required in winter

• Regular cleaning and maintenance

4. Analysis of typical application scenarios

1. Best applicable scenarios

• Winter heating in the Yangtze River Basin

• New energy-saving housing

• A place with high comfort requirements

• Areas without gas supply

2. Scenarios that need to be carefully chosen

• extreme low temperature areas

• Places for intermittent use

• Renovation of old buildings

• Areas with unstable electricity

 5. Comparison with other heating methods

6. Purchase suggestions

1. Brand Selection: Give preference to professional heat pump brands

2. Model matching: select the appropriate capacity according to the heating area

3. System design: Find a professional HVAC company to design

4. Installation and construction: Choose a qualified installation team

5. After-sales service: confirm the perfect after-sales system

Air energy floor heating heat pump systems are becoming the preferred solution for modern home heating due to their excellent energy saving, comfort and environmental friendliness. Although the initial investment is high, the long-term cost advantage is obvious, making it a wise choice for families pursuing quality life.
