FAQ
Q: What is the advantages of Air Source Heat Pump?
A: 1. High energy saving efficiency
Direct heating by electric energy is relatively inefficient, and one kilowatt-hour of electricity can only produce one share of heat energy, which is one of the reasons for the high electricity bill when electric heating is used in winter. The working principle of the air source heat pump is slightly different. The compressor is driven by low power to absorb the low-grade heat energy in the air and convert it into high-grade heat energy, which is then used for indoor heating. Consuming 1 degree of electricity can get more than 3 parts of heat energy. Therefore, the electric energy consumed by the air source heat pump to produce the same heat is very low, and it is a very efficient energy-saving heating equipment.
2. High environmental protection and safety
When the air source heat pump is working, it only consumes electric energy and does not rely on natural gas, coal, oil and other non-renewable resources. Therefore, there will be no open flames, no pollutant emissions, and no pollution to the environment. It is highly environmentally friendly. At the same time, the power system of the air source heat pump is concentrated in the outdoor unit, and the heat is transmitted to the room through water, so that water and electricity can be separated, and the room will not be exposed to the power supply, which has good safety. Compared with other heating equipment, it can avoid fire and explosion. , poisoning, electric shock and other risks. Even if the fan coil unit is used for heating in winter, it will not bring danger indoors. The indoor pipes are full of water. If there is leakage, it will only wet the ceiling, and there will be no leakage of refrigerant from the fluorine air conditioner, which will reduce the fluoride content in the room. If it is too high, it will affect your health.
3. Low cost of use
The air source heat pump uses 1 kilowatt-hour of electricity to generate 3 parts of heat energy. Compared with air conditioning and electric heating, it can save 2/3 of the cost of use, and can save 1/2 of the cost of gas wall-hung boiler heating. Compared with central heating, it can also About 30% cheaper. If the heating area is 100 square meters, using air conditioners and electric heaters, the cost of day and night operation is at least 3,000 yuan, and the use of gas wall-hung boilers for heating is also day and night operation, and the cost is about 1,500 yuan. 500 yuan is enough. Of course, the cost cannot be compared with coal-fired heating, but it is higher than coal-fired heating in terms of energy cleanliness, cleanliness, convenience, and sanitation.
4. High heating comfort
The air source heat pump mainly uses the water system to work, and the heating end can be carried out through fan coils, floor heating and radiators. In terms of comfort, floor heating is well-deserved first. The indoor coils are evenly laid, and the temperature is evenly dissipated. High transmission, heat the feet first and then the body, so that the temperature feeling of warming the feet and cooling the roof is the most comfortable heating solution at present.
Not only that, the air source heat pump is also very comfortable when cooling in summer. Chilled water is generated by the heat pump host and circulated to the indoor fan coil for heat exchange. The indoor temperature is very constant (the inertia of water), and the outlet air temperature of the water system air conditioner is only 12°C-15°C, compared with fluoride air conditioners At a low temperature of 7°C-10°C, the air outlet is softer, the air outlet temperature is higher, the temperature fluctuation is smaller and the impact on humidity is smaller.
5. Wide range of use
Air source heat pumps use low electric energy to absorb heat in the air, and can be used as long as there is electricity, water, and air (the temperature is above -25°C), and are not affected by light and energy, and are less affected by the environment . The application of the air source heat pump to the air injection enthalpy increase technology makes the ability to adapt to the ambient temperature stronger, and it can be heated at -35°C-48°C, which can meet the use in most regions of the world.
6. Good stability
All the refrigerants used by air conditioners are fluorides, while the refrigerants used by air source heat pumps include fluorides and water. Fluorides are used in the main unit and water is used in the indoor part. In contrast, water is more inert and can last longer. The heat absorbed by the air energy heat pump can be stored in the water for a longer period of time, making the indoor temperature more constant, and reducing the frequent operation of equipment, so that it can be more energy-saving while maintaining stability.
7. Strong intelligent ability
The air source heat pump host is controlled by a microcomputer. When debugging, set the required parameter configuration, and the host will automatically adjust the amount of water replenishment, heating, power-off protection, water tank insulation and Heating and other work do not require complex operation control panels, and the air source heat pump can be connected to the smart 485 interface, and the air source heat pump system is compatible with the intelligent equipment of the whole house to realize remote intelligent control.
8. Long service life
The service life of gas water heaters is about 8 years, and the service life of gas wall-hung boilers can reach 15 years, but the gas quality and water quality must be good, otherwise the service life of the equipment will be scrapped after a few years of use. However, the design life of the core components of the air source heat pump is more than 15 years, which can cope with the impact of power aging and scale problems. Of course, regular maintenance can also increase the service life of the equipment.
9. Simple installation conditions
Although the air source heat pump is relatively large in size, it has certain installation space requirements. However, the installation of air source heat pumps is not limited by geology, pipelines and energy supply. The normal operation of the main engine can be realized in places with air circulation, and there is no excessive demand for power equipment, which is equivalent to the power distribution of ordinary air conditioners. Don't worry The troubles caused by insufficient power at home and capacity expansion can be used in large and small houses.
