The air source heat pump heating system mainly uses air source heat pump as the heating source, and completes the heating of the room by combining with the heating terminal. The principle of air source heat pump is to use the reverse Carnot principle to absorb a large amount of low-temperature heat energy in the air with very little electric energy, and convert it into high-temperature heat energy through the compression of the compressor. It is an energy-saving and efficient heat pump technology.
The above introduces the principle of air source heat pump heating system, so let's talk about the advantages and disadvantages of air source heat pump heating system.
Advantages of air source heat pump heating system
1. Comfort
The heat of air source heat pump heating rises from the feet, making the temperature of the entire indoor space evenly distributed, without the feeling of hot wind, which is beneficial for the body to retain moisture, and has a positive therapeutic effect on rheumatism and asthma;
2. Energy saving
Air source heat pump underfloor heating uses 35-50℃ (convection radiator requires 85℃), and the heat is concentrated within the beneficial height of the human body (below 2 meters), which saves 75% energy compared with traditional electric heating methods;
3. Save space (inside room space)
Air source heat pump underfloor heating lays water pipes under the floor, saving space and can be matched with different decoration styles;
4. Long service life
The pipes used in air source heat pump underfloor heating are buried underground, without scaling, corrosion, and human damage, and the service life is synchronized with the building. Compared with traditional central air conditioning and radiator heating, it saves maintenance and replacement costs.
5. Safety
The rooms with heating in winter are well sealed. If gas heating products are used, there will be a risk of carbon monoxide poisoning, but there is no need to worry about such problems with air source heat pump heating.
6. Cost comparison
Natural gas combustion and air source heat pump The price of natural gas is rising day by day. The price of natural gas a year ago is incomparable to the current price. However, the price of natural gas will be more expensive in the future, and the trend is only increasing. Faced with the current situation of rising natural gas prices and mandatory requirements for building energy conservation, and because air source heat pumps save more than 30% energy than traditional natural gas heating, they are becoming more and more popular for heating.
Disadvantages of air source heat pump heating system
1. It is easily affected by the surrounding air environment. When the weather is cold and the ambient temperature is low, the amount of hot water produced will be slightly reduced. Especially at -10℃, it is easy to frost, and below -20℃, the unit stops working. The problem of defrosting is a difficult problem that needs to be solved urgently.
2. The air source heat pump is relatively large in size and requires installation on the ground or roof, which has higher requirements for the home environment.
3. The compressor is easy to burn out. At present, the air source heat pumps on the market generally use a circulating heating system. When operating under high temperature and high pressure, it is easy to age and carbonize the compressor. If the system lubrication effect is not good, it is easy to cause the compressor to burn out.
4. The heat exchanger and the shell and tube heat exchanger are easy to scale and break, because the outlet water temperature of the air source heat pump can reach 50-60℃. Water is most likely to scale in this temperature range. If the heat exchanger is not cleaned regularly, the plate heat exchanger will swell and burst, and the inner tube of the shell and tube heat exchanger will rupture, causing the entire unit to lose its function.
Final summary
When used in winter, the power consumption of the air source heat pump is similar to that of the air conditioner, and in summer, it is more energy-saving than the air conditioner. In terms of health, it is the best choice, especially for families with elderly people and children. However, the air source heat pump is different from radiators and wall-mounted boilers after all, and has decades of technical accumulation.
