First understand the working principle of this hot air blower:
Like the air source heat pump, the hot air blower is also a high-efficiency thermal energy lifting and transferring device based on the reverse Carnot cycle. It uses a small amount of electric energy as power to transfer the low-temperature heat in the outdoor air to the indoor air through the refrigerant to achieve indoors. Heating. Compared with heat pump heating, the hot air blower heats up the indoor temperature by heat exchange between the high temperature refrigerant and the indoor air. The air source heat pump hot water machine heats the water through the heat exchange between the refrigerant and the water, and then circulates through the hot water at the end. To increase the indoor temperature.
Execution standard: air source heat pump heating unit implements national standard GB/T 25127.2-2010, nominal heating condition is dry bulb temperature/wet bulb temperature -12°C/-14°C (use side outlet temperature 41°C), nominal condition The heating coefficient of performance (COP) is not less than 2.1, and the heating IPLV (H) is not lower than 2.4; while the heat pump hot air blower does not currently have the relevant national standard, and the nominal heating condition is the outdoor dry/wet bulb temperature -12 °C/- 13.5 ° C; ultra-low temperature heating conditions are outdoor dry bulb temperature -20 ° C, the applicable range is -25 ~ 43 ° C.
This product can not only operate stably in the extreme low temperature environment in the north, but also provide energy-saving heating demand for the family, and it is easy to install and has the advantages. It has become the "eye-catching tool" of the China Heat Pump Exhibition, and its popularity is very popular.
Advantage 1: Cost is appropriate, low investment is low
1. Compared with other heating methods, equipment costs are lower;
2. Compared with other installation methods, the installation is simple and the cost is low;
3. It is especially suitable for coal-to-electricity projects with less government investment.
Advantage 2: make up for the lack of air conditioning heating and other high heating equipment cost
1. The traditional air conditioner has basically no heating capacity below 0 °C, and the hot air blower can operate normally at -30 °C;
2. The hot air blower only needs copper pipe to connect the internal and external machines, and the construction and transformation are convenient.
Advantage three: DC frequency conversion, extreme speed heating
1. Heating DC variable frequency drive, fast operation under low ambient temperature, rapid heating, two minutes warm room;
2. Under higher ambient temperature, the system automatically sets the frequency operation, and quickly heats up to achieve energy saving purposes;
3, variable frequency drive, to deal with the problem of grid voltage instability.
Advantage 4: Adopt high efficiency double rotor compressor
The high-efficiency double-rotor compressor is used to effectively reduce the vibration during start-up and operation of the compressor, and make the compressor run more smoothly and quietly. The 180° sine wave drive technology makes the motor run more smoothly, and the PFC precision drive technology greatly improves the operation efficiency and reduces the noise. The minimum speed is up to 20rps and the performance is better under partial load.
Advantage 5: Adopt R401A environmentally friendly refrigerant, in line with the bidding requirements
R410A's new environmentally friendly refrigerant is non-toxic, stable and will not destroy the ozone layer. The pressure loss is about 60% of the ordinary R22 air conditioner, and the refrigeration (warm) efficiency is higher. It is recognized as a substitute for future refrigerants.
Advantage 6: Use a scroll fan for more comfortable use
The vortex fan is equipped with multi-speed motor, silent mode, strong mode free choice; winter heating is comfortable.
“This is a black technology that has broken through the technology of air source heat pump industry. When the air source heat pump was promoted, because of the high price, it can only sell energy-saving advantages and sell appearance advantages, but the appearance of hot air blower products is not only more energy-saving, but also has a small appearance. It also has the advantages of more convenient installation, forced heat at low temperature, and more powerful functions.
Through the above introduction, do you think that this hot air blower is an artifact for winter heating?
